Description
Technical Field

Background
In the related art, when a user approaches the air conditioner during the use of the air conditioner, if the air supply capacity of the fan of the air conditioner is still unchanged, the user can obviously feel that the air blows on the user, and particularly when the air conditioner is in a cooling mode, the user is easy to catch a cold. Therefore, it is necessary to effectively prevent the air conditioner from blowing cold air directly during the use of the user.
In addition, when a user approaches the air conditioner, the air guide mechanism of the air conditioner often has a risk of pinching hands during movement, and if a person, particularly an infant or a child, extends the hands into the air guide mechanism (for example, an air outlet grille), the pinching hands are easy to occur. In the related art, in order to avoid the occurrence of the hand clamping situation, whether the air guide mechanism rotates to the hand clamping position is often detected through modes such as a photoelectric switch or a hall sensor, and when the air guide mechanism is about to rotate to the hand clamping position, the pause is controlled by a program for a set time, and then the air guide mechanism continues to rotate. Therefore, even if fingers of a person stretch into the air guide mechanism, the fingers are in danger of clamping hands or are just clamped into the hands, and the fingers can be separated within a set time length.

Detailed Description
The present application will be described in further detail with reference to the following drawings and examples.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
The embodiment of the application provides a control method of an air conditioner, and the air conditioner is used for adjusting the temperature, the humidity and the like of an environment. The air conditioner can be a single-cooling air conditioner or a cooling and heating dual-purpose air conditioner, and the air conditioner can be in the form of a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner or a ceiling air conditioner, and the like, and the embodiment of the application is not particularly limited to this.
In order to effectively solve the problems of direct blowing users and hand clamping risks of the air conditioner in the related art, in various embodiments of the application, the air conditioner is reasonably controlled to be switched to a non-wind-sensing mode based on the relative distance between the air conditioner and an external object, and the function of preventing hands from being clamped is realized based on the relative distance in the process of switching to the non-wind-sensing mode.
Before describing the control method of the air conditioner in the embodiment of the present application, the air conditioner in the embodiment of the present application will be described. The air conditioner of the embodiment of the application includes: the air conditioner comprises at least one air outlet, an air guide mechanism arranged at the air outlet and a distance detection device used for detecting the relative distance between the air conditioner and an external object.
Here, the number of the outlet ports may be one or more. For example, for a wall-mounted air conditioner, an air outlet may be disposed on a front surface of the wall-mounted air conditioner, and an air guiding mechanism for guiding air is disposed at the air outlet. For a vertical cabinet air conditioner (also called a cabinet air conditioner), at least two air outlets can be formed on a wall body of the vertical cabinet air conditioner to cover different areas, and correspondingly, air guide mechanisms for guiding air can be respectively arranged at the air outlets.
The air conditioner has a wind sweeping mode and a no-wind mode, and the wind guide mechanism is used for controlling the change of the air outlet direction at the air outlet in the wind sweeping mode; in the non-wind mode, the wind guide mechanism is used for preventing the air conditioner from blowing directly to a user. In one application example, the air guide mechanism comprises: the air conditioner operates in a wind sweeping mode by controlling the air guide strips to change postures; the air conditioner can also control the air guide strip to be in the posture of shielding the air outlet, and the air is diffused through the through hole formed in the air guide strip, so that the air conditioner operates in a no-wind-sense mode. In another application example, the air guide mechanism comprises: the first actuating mechanism that rotary drum and drive rotary drum removed, the rotary drum includes: the air conditioner controls the first driving mechanism to drive the rotary drum to reciprocate so as to change the opening angle of the air outlet and operate in a wind sweeping mode; the air conditioner can also control the first driving mechanism to drive the grid plates of the rotary drum to move to a position opposite to the air outlet, and the air conditioner operates in a no-wind-sense mode. Here, because the grid plate is opposite to the air outlet, the wind at the air outlet needs to be dispersed by the grid holes on the grid plate and then discharged, thereby effectively avoiding the direct blowing user.
Here, the distance detection means may be a detector based on infrared detection, laser detection, microwave detection, or radar detection. It is understood that the relative distance between the air conditioner and the external object, i.e., the relative distance between the distance detection device and the external object, is only required to be able to detect the relative distance between the external object (i.e., the user) and the air conditioner. Wherein the detector based on infrared detection includes at least one infrared emitter for emitting infrared rays and at least one infrared receiver for receiving reflected infrared rays and determining the position of the external object based on the received infrared rays. The detector based on laser detection comprises at least one laser emitter for emitting a laser signal and at least one laser receiver for receiving the reflected laser signal and determining the position of the external object based on the received laser signal. The microwave detection based detector comprises at least one microwave emitter for emitting a microwave signal and at least one microwave receiver for receiving the reflected microwave signal and determining the position of the external object based on the received microwave signal. The detector based on radar detection includes a transmitter for transmitting electromagnetic waves and a receiver for receiving the reflected electromagnetic waves, the receiver determining the position of the external object based on the reflected electromagnetic waves.
It can be understood that, if the number of the air outlets is plural, each air outlet may be respectively provided with a distance detection device or at least two air outlets share one distance detection device. It should be noted that, if there is no risk of blowing directly or pinching hands in some of the outlets, the distance detection device may not be needed.
As shown in fig. 1, the method for controlling an air conditioner according to the embodiment of the present application includes:
in step 101, a distance value of a relative distance between an air conditioner and an external object is obtained.
Here, the air conditioner may periodically or non-periodically acquire a distance value of a relative distance to the external object based on the distance detection device during operation of the air conditioner, for example, the air conditioner periodically actively collects the distance value detected by the distance detection device or the air conditioner receives the distance value periodically transmitted by the distance detection device.
And 102, determining that the distance value is smaller than or equal to a first distance threshold value, and controlling the air guide mechanism to move to a set position so as to start the no-wind-sense mode of the air conditioner.
Here, the air conditioner compares the acquired distance value with a first distance threshold value, and if the distance value is determined to be smaller than or equal to the first distance threshold value, it is determined that the distance from the user to the air outlet is short, and it is necessary to control the air guide mechanism to move to a set position to start the no-wind mode of the air conditioner. Here, the set position is a position corresponding to the air guide mechanism when the air conditioner is operated in the no-wind mode. For example, if the air guide mechanism adopts a shutter type air guide bar, the air guide bar is controlled to be in a posture of shielding the air outlet, and air is dispersed through a through hole formed in the air guide bar, so that the air conditioner operates in a no-wind-sense mode; if the wind guide mechanism adopts a rotary drum, the grid plates of the rotary drum are controlled to move to the position opposite to the air outlet, and the wind guide mechanism operates in a non-wind-sensing mode.
It can be understood that, after the air guide mechanism moves to the set position, even if a user is close to the air outlet, the user does not have obvious wind sense because the air quantity at the outlet wind position is scattered. Especially aiming at the refrigeration mode, the direct blowing of cold air can be reduced, and the cold catching of a user is avoided.
For example, the air conditioner may further adjust the frequency of subsequently acquiring the distance value based on the current distance value, for example, if it is determined that the current distance value is greater than the first distance threshold, the distance value is acquired based on the first frequency, that is, the distance value detected by the distance detection device is actively acquired at the first frequency, or the distance value sent by the distance detection device at the first frequency is received. And if the current distance value is determined to be smaller than or equal to the first distance threshold value, acquiring the distance value based on the second frequency. Here, the second frequency is greater than the first frequency, that is, the time interval between two adjacent distance values obtained at the second frequency is less than the time interval between two adjacent distance values obtained at the first frequency, so that when the distance value between the user and the air conditioner is greater than the first distance threshold, the power consumption of the distance detection device can be effectively reduced, and when the distance value between the user and the air conditioner is less than or equal to the first distance threshold, the frequency for obtaining the distance value is increased, and whether the hand clamping risk exists can be determined in time.
It should be noted that, determining that the current distance value is greater than the first distance threshold includes a situation that the distance detection device cannot currently detect the external object, taking an infrared detection-based detector as an example, if the infrared receiver does not receive the reflected infrared rays, it indicates that the external object does not exist in the current detection area, and determining that the current distance value is greater than the first distance threshold.
And 103, in the process of controlling the air guide mechanism to move, determining that the distance value is smaller than or equal to a second distance threshold value, and controlling the air guide mechanism to stop moving before moving to the set position.
Here, the first distance threshold is greater than the second distance threshold. The air conditioner compares the acquired distance value with a second distance threshold value, if the distance value is determined to be smaller than or equal to the second distance threshold value, it is determined that the distance from the user to the air outlet is too short and the hand clamping risk exists, and the air guide mechanism needs to be controlled to stop moving before moving to the set position, namely, stop moving in advance, so as to avoid the hand clamping of the air guide mechanism.
It can be understood that, in the process that the air conditioner controls the air guiding mechanism to move to the set position, a user may pinch his/her hands due to the action of the air guiding mechanism, and at this time, if the user continues to approach the air conditioner and the distance value is smaller than or equal to the second distance threshold value, the air guiding mechanism may be controlled to stop moving before moving to the set position, so as to avoid pinching his/her hands by the air guiding mechanism.
In some embodiments, controlling the air guiding mechanism to stop moving before moving to the set position comprises:
controlling the air guide mechanism to immediately stop moving in response to the distance value being smaller than or equal to the second distance threshold; or,
and controlling the air guide mechanism to move to the anti-pinch limit position and then stop moving in response to the distance value being smaller than or equal to the second distance threshold value.
Here, the limit position may be determined reasonably based on experiments, for example, the limit position may be a position corresponding to a reasonable safety distance between the rotary drum and the side edge of the air outlet. It can be understood that if the air guide mechanism is controlled to move to the limit position for preventing hands from being clamped and stop moving, the air quantity of the direct-blowing human body can be minimized while hands are not clamped.
The air conditioner of the embodiment of the application can start the air conditioner to be switched to the no-wind-sense mode to operate when the user is determined to be close to the air conditioner (namely the distance value is smaller than or equal to the first distance threshold value) based on the detected distance value, so that the air conditioner is prevented from directly blowing the user; and in the process of switching to the no wind sensation mode, if the user is too close to the air conditioner (namely, the distance value is less than or equal to the second distance threshold), the hand clamping prevention function can be automatically realized, so that the unification of preventing the direct blowing user and the hand clamping in the operation process of the air conditioner is realized, the operation safety is improved, and the comfort in the operation process is also improved.
Here, the first distance threshold and the second distance threshold may be reasonably determined based on experiments. The air conditioner may store the first distance threshold and the second distance threshold locally in advance, or acquire the first distance threshold and the second distance threshold from the network side. For example, the air conditioner may further adjust the first distance threshold and/or the second distance threshold within a reasonable interval based on the indication information of the user, for example, the user may adjust the first distance threshold and/or the second distance threshold within a set range according to a personalized requirement, which is not specifically limited in this application.
In some embodiments, the control method in the embodiments of the present application further includes:
and determining that the distance value is greater than the second distance threshold and less than or equal to the first distance threshold, and controlling the air guide mechanism to continue moving until the set position is reached.
After the air guide mechanism is controlled to stop moving in advance (namely, the air guide mechanism stops moving before reaching the set position), if the air conditioner determines that the distance value is larger than the second distance threshold and smaller than or equal to the first distance threshold, the air conditioner determines that the user is separated from the hand clamping risk and still needs to avoid direct blowing, and the air conditioner controls the air guide mechanism to continue moving until reaching the set position, so that the air conditioner operates in a non-wind-sensing mode. Compared with the traditional control strategy that the air guide mechanism pauses based on the set duration, the control method of the embodiment of the application can recover the movement of the air guide mechanism after determining that the user is away from the hand clamping risk, and the safety is higher. Especially for the groups such as infants or children, the hand clamping risk caused by not removing the hands in time can not occur.
For example, if it is determined that the current distance value is less than or equal to the second distance threshold, the air conditioner acquires the distance value based on the third frequency, that is, actively acquires the distance value detected by the distance detection device at the third frequency, or receives the distance value sent by the distance detection device at the third frequency. Here, the third frequency is greater than the second frequency, that is, the time interval between two adjacent distance values obtained at the third frequency is smaller than the time interval between two adjacent distance values obtained at the second frequency, so that the corresponding sampling interval after the air guide mechanism stops moving in advance can be effectively reduced, the air guide mechanism can timely resume moving, and the mode is switched to the non-wind-sensing mode. Therefore, the safety of preventing hands from being clamped is considered, and direct blowing users of the air conditioner can be effectively reduced.
It can be understood that, in the process that the air conditioner determines that the distance value is less than or equal to the first distance threshold value, and the air guide mechanism is controlled to move to the set position, if the distance value is not less than or equal to the second threshold value, the air conditioner can be directly switched to the no-wind-sensation mode and operate in the no-wind-sensation mode until the air conditioner determines that the distance value is greater than the first distance threshold value, the no-wind-sensation mode exits, and the original control mode is restored, that is, the air conditioner is controlled to operate based on the latest user instruction.
In some embodiments, the drum further comprises: set up in the inboard backup pad of grid plate, install the second actuating mechanism of rotating vane and drive rotating vane pivoted in the backup pad, the air conditioner is under no wind-sensing mode, and this application embodiment control method still includes: and controlling the second driving mechanism to drive the rotating blade to rotate.
It can be understood that one side of grid plate towards the user is the outside, and the one side relative with the outside is the inboard, sets up a plurality of commentaries on classics leaves through setting up the backup pad in the inboard, rotates under the drive of second actuating mechanism that the commentaries on classics leaf was in the backup pad, and the inside wind of air outlet can be earlier through the whirl output that commentaries on classics leaf department formed, is broken up the output by the grid hole again, and the rotational speed of commentaries on classics leaf is faster, and the whirl effect is better. Taking the refrigeration mode as an example, the cold output effect in the absence of wind can be further improved.
In some embodiments, the air conditioner is in a no-wind-sensation mode, and the control method in the embodiments of the present application further includes:
acquiring an ambient temperature;
and controlling the rotating speed of a fan and/or the rotating speed of the rotating blade of the air conditioner based on the ambient temperature and the set working temperature.
Here, the air conditioner can acquire the ambient temperature collected by the temperature sensor, compare the ambient temperature with the set working temperature, and control the rotating speed of the fan and/or the rotating speed of the rotating blade in the no-wind-sensation mode based on the temperature difference, so that the rotating speed of the fan in the no-wind-sensation mode can be adjusted to balance the heating or refrigerating effect and avoid the contradiction between the direct blowing users of the air conditioner, and further improve the user experience in the no-wind-sensation mode. Illustratively, taking the cooling mode as an example, if the acquired ambient temperature is T1, the set operating temperature is T0, and assuming that Δ T is T1-T0, if Δ T is less than or equal to a first temperature difference threshold, the fan is controlled to operate at a first rotation speed, and if Δ T is greater than the first temperature difference threshold, the fan is controlled to operate at a second rotation speed, wherein the first rotation speed is less than the second rotation speed. Correspondingly, the rotating speed of the rotating blade can be increased when the fan operates at the first rotating speed, and the rotating speed of the rotating blade is reduced when the fan operates at the second rotating speed. It can be understood that the faster the rotation speed of the rotating blade, the better the cyclone effect, when the fan operates at the first rotation speed, the rotation speed of the rotating blade is increased, the direct blowing human body can be avoided through the cyclone, when the fan operates at the second rotation speed, the rotation speed of the rotating blade can be reduced, and the effect of better avoiding the air quantity to directly blow the human body can be obtained.
In some embodiments, the air conditioner further comprises: a switch door for opening and close air outlet, this application embodiment control method still includes: and in the process of controlling the switch door to close the air outlet, determining that the distance value is smaller than or equal to a second distance threshold value, and controlling the switch door to stop moving before closing the air outlet.
It can be understood that, after receiving a shutdown instruction indicated by a user, the air conditioner may control a compressor, a fan, and other mechanisms of the air conditioner to stop operating, and control the switch to close the air outlet. Here, the opening and closing door can automatically open or close the air outlet under the driving of the motor. In the process that the air conditioner controls the switch door to close the air outlet, because the opening between the switch door and the side edge of the air outlet is smaller and smaller, if the distance between the user and the air conditioner is smaller than or equal to the second distance threshold value at the moment, the hand clamping risk may exist. Based on this, in the in-process of closing the air outlet at the switch door, if the distance value is less than or equal to second distance threshold value, then can control the switch door and stop moving immediately or control the switch door and remove and stop moving after preventing the extreme position of tong, this extreme position can rationally confirm based on the experiment, for example, the extreme position can be for having the position that reasonable safe distance corresponds between switch door and the air outlet side.

and determining that the distance value is greater than a second distance threshold value, and controlling the switch door to move continuously to close the air outlet.
After the switch door is controlled to stop moving, if the air conditioner determines that the distance value is larger than the second distance threshold value, it is determined that the user is away from the hand clamping risk, and the air conditioner controls the switch door to continue moving until the air outlet is closed, so that the shutdown is completed. The control method of the embodiment of the application can restore the movement of opening and closing the door after determining that the user is out of the hand clamping risk, and the safety is higher. Especially for the groups such as infants or children, the hand clamping risk caused by not removing the hands in time can not occur.

The first air outlet 2A is also provided with a first switch door 5A capable of opening and closing the first air outlet 2A, and the second air outlet 2B is also provided with a second switch door 5B capable of opening and closing the second air outlet 2B.

The grating holes 311 may be uniformly opened on the grating plate 31. The inner side of the grid plate 31 is provided with a support plate 32, for example, the support plate 32 can be connected to the inner side of the grid plate 31 in a clamping, inserting and other manners, the rotating blades 33 and the shutters 34 are installed on the support plate 32, the rotating blades 33 and the shutters 34 are arranged in a one-to-one correspondence manner, the rotating blades 33 and the shutters 34 are driven by a second driving mechanism through a connecting rod 35, for example, a stepping motor drives the connecting rod 35 to reciprocate, so that the rotating blades 33 are driven to rotate when the shutters 34 are driven to swing up and down, and the rotating blades 33 realize the function of wind dissipation. Illustratively, the grating plate 31 may be driven by the first driving mechanism at the air outlet to swing left and right at the air outlet, thereby driving the entire drum to swing left and right together.
Exemplarily, as shown in fig. 5, a first distance detection device 4A is disposed at a lower side of the first outlet 2A, and a second distance detection device 4B is disposed at a lower side of the second outlet 2B. Here, the first distance detection device 4A and the second distance detection device 4B may be detectors based on infrared detection, and may also be detectors based on radar detection. Taking the detector based on infrared detection as an example, the left detector based on left red detection and the right detector based on infrared detection on the left side receive infrared rays in the left and right detection ranges respectively, and the detection directions of the left and right detectors based on infrared detection are the same or substantially the same as the air blowing direction of the air conditioner, so that whether a human body approaches in the air blowing direction of the air conditioner can be detected.

It should be noted that, when each rotating drum, the fan, the opening and closing door, etc. move independently, the corresponding first driving mechanism, the second driving mechanism, the fan motor and the door motor also need to be arranged independently. For example, a first fan motor is arranged on the first air outlet 2A side, a second fan motor is arranged on the second air outlet 2B side, the first rotary drum 3A and the second rotary drum 3B are respectively provided with an independent first driving mechanism and an independent second driving mechanism, and the first opening and closing door 5A and the second opening and closing door 5B are respectively provided with an independent door motor.

Here, if the air conditioner determines that the distance L corresponding to the presence of the external object at least one of the first outlet 2A and the second outlet 2B is less than or equal to L1 based on the first detection result and the second detection result, indicating that the corresponding outlet needs to perform the function of preventing the direct blowing of the cold wind, step 604 is executed to control the air guiding mechanism to move so as to start the no-wind-sensation mode. If the first detection result and the second detection result indicate that the distances L corresponding to the external objects are both greater than L1, it indicates that the first outlet 2A and the second outlet 2B do not need to execute the function of preventing the direct blowing of the cold air, and the air conditioner may continue to operate based on the current operation parameters, that is, the air conditioner does not need to change the control strategy, and step 603 is executed.

Here, the set position refers to a position where the rotary drum is opposite to the air outlet, that is, a position where the rotary drum is located in the no-wind mode of the air conditioner.
It can be understood that, if the first outlet 2A and the second outlet 2B are both required to perform the function of preventing the cold wind from blowing directly, the first rotating drum 3A and the second rotating drum 3B are both controlled to start swinging towards the set positions of the outlets. If only one of the first outlet 2A and the second outlet 2B needs to perform the function of preventing the direct blowing of the cool air, the drum that needs to perform the function of preventing the direct blowing of the cool air can be controlled to swing toward the set position of the outlet.
At step 605, it is determined whether the distance L is less than or equal to L2. If yes, executing a step 606, and operating an anti-pinch control strategy; if not, go to step 607.
Here, the drum (which may be the first drum and/or the second drum) corresponding to the air outlet that needs to perform the function of preventing the direct blowing of the cool air is controlled to swing along the position covering the air outlet, and it is determined whether the current distance L is less than or equal to L2 based on the latest distance L, if so, step 606 is performed, and if not, step 607 is performed.
And 606, controlling the air guide mechanism to move to the anti-pinch limit position and then stopping moving.
Here, the air conditioner can stop moving after first actuating mechanism drive rotary drum removes the extreme position that prevents pressing from both sides the hand, and this extreme position can rationally be confirmed based on the experiment, for example, the extreme position can be for having the position that reasonable safe distance corresponds between rotary drum and the air outlet side. The air conditioner also continues to step 607 after determining that the distance L is greater than L2.
And step 607, controlling the air guide mechanism to move to a set position and operating in a no-wind-sense mode.
The air conditioner drives the rotary drum to move to a position opposite to the air outlet at the position through the first driving mechanism, the air conditioner can cover the air outlet, the rotary vanes are controlled to rotate under the driving of the second driving mechanism, air in the air outlet can be output through the rotational flow formed at the rotary vanes firstly, then the air is scattered and output through the grating holes, the higher the rotating speed of the rotary vanes is, the better the rotational flow effect is, and the cold output effect in the absence of wind can be further improved.
As shown in fig. 7, the control method of the air conditioner of the present application example further includes:
and step 701, starting door closing control of the opening and closing door based on the control instruction.
Here, the air conditioner may control a compressor, a fan, and other mechanisms of the air conditioner to stop operation and start door closing control of the opening and closing door after receiving a shutdown instruction instructed by a user.
In step 702, during the door closing process of the opening/closing door, it is determined whether the distance L is less than or equal to L2. If yes, go to step 703; if not, go to step 704.
Here, the air conditioner may obtain the distance L detected by the distance detecting device during the door closing process of the opening and closing door, and determine whether the distance L is less than or equal to L2, if so, it indicates that there is a hand clamping risk, and execute step 703, otherwise, execute step 704.
And 703, controlling the switch door to move to the anti-pinch limit position and then stopping moving.
Here, the door body motor can drive the switch door and move and stop moving after moving to the extreme position of preventing tong, and this extreme position can rationally confirm based on the experiment, for example, the extreme position can be for having the position that reasonable safe distance corresponds between switch door and the air outlet side. The air conditioner also continues to step 704 after determining that distance L is greater than L2, i.e., the user is outside of a reasonable anti-pinch distance.
And controlling a door motor to drive the opening and closing door to move continuously until the air outlet is closed.
