technical field

The present application relates to the technical field of wind deflector design, for example, to a wind deflector assembly, a method for controlling the wind deflector assembly, and a processing system.

Background technique

At present, air conditioners have become an indispensable household appliance in family life. As an important part of the air conditioner, the air deflector is used to control the direction of the air flow and open and close the air outlet. During the working process of the air conditioner, air with a large temperature difference from the current indoor ambient temperature is usually sent out from the air outlet of the air conditioner, and the wind will flow through the inner surface of the air deflector, causing the temperature of the inner surface of the air deflector to change.

For the indoor unit of the wall-mounted air conditioner, the air deflector is generally made of ABS (Acrylonitrile Butadiene Styrene plastic, acrylonitrile-butadiene-styrene plastic) and other plastic materials, which are prone to deformation under the action of temperature. For example, in the cooling state, the air deflector will produce internal stress depression and deformation under the action of cold wind, and the initial closed state of the air deflector when the machine is turned off is shown in Figure 1, and the appearance gap will be uneven; in the heating state, the air deflector Under the action of hot air, there will be internal stress and outward convex deformation. The initial closed state of the air deflector when the machine is turned off is shown in Figure 2, and the apparent gap is not uniform. Due to the variety of structures of the air deflector, different structures of the air deflector will cause various deformations of the air deflector when it is heated or cooled, and various inhomogeneities will also occur in the appearance gap.

In the related art, an air duct assembly is provided, including an air outlet frame provided with an air outlet, an air deflector assembly arranged at the air outlet, and a force applying assembly arranged between the air deflector assembly and the air outlet frame assembly During this period, when the wind deflector assembly is in the closed position, the force applying component exerts an attractive force on the wind deflector assembly, so that the wind deflector assembly is close to the edge of the air outlet, thereby solving the gap between the air deflector assembly at the closed position. The problems of uniformity and excessive gaps have improved the appearance level of the air conditioner.

In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies:

Due to the diversity of the structure of the wind deflector, the degree of deformation at different positions is different. As shown in Figure 3, for the position with large deformation, the fixed suction adjustment through the force application component may not be able to attract. Therefore, the ideal gap adsorption effect cannot be achieved, and the shape recovery adjustment of the air deflector is affected, which affects the appearance level of the air conditioner.

Fig. 7 is a control method for the air deflector assembly provided by this embodiment, which is applied to an air conditioner with the above air deflector assembly. The control method for the air deflector assembly can be executed in the air conditioner, or can be executed in the control terminal of the air conditioner, such as a remote control, an operation panel; it can also be executed in a server, such as a home cloud platform communicating with the air conditioner; Executed in a terminal device, such as a smart phone, a smart home appliance or a control terminal of a smart home system. In the embodiment of the present disclosure, the solution is described by taking the processing system of the wind deflector as the execution subject.

Step S701, the processing system receives the deformation parameters of the wind deflector provided by the detection device to determine the degree of deformation of the position where the detection device is located.

Wherein, the deformation parameter is used to represent the attribute value related to the reason for the deformation of the wind deflector, and/or the attribute value related to the current state. Different detection devices have different working principles, and the detected attribute values used to determine the deformation parameters are different.

For example, the material of the wind deflector is generally ABS plastic, which will be deformed under the influence of the air outlet temperature. That is, the attribute value of the cause of the deformation of the wind deflector may include a temperature attribute. The temperature attribute of the position on the wind deflector can be obtained by detecting the device, so as to obtain the deformation parameter.

For another example, the air deflector is connected to the frame where the air guide is located through a rotating shaft. Therefore, the position where the deformation occurs generally has a certain distance from the connection point of the wind deflector and the rotating shaft, and the farther the distance is, the greater the degree of deformation is. Therefore, the attribute value of the reason for the deformation of the wind deflector may include the attribute of the distance between the detection component and the connection point between the wind deflector and the rotating shaft. The distance attribute between the wind deflector and the above-mentioned connection point can be obtained through the detection device, so as to obtain the deformation parameter.

For another example, after the air deflector is deformed, a gap is formed between its edge and the air guide opening in the closed state, and different gap distances can reflect different degrees of deformation. Therefore, the attribute value related to the current state of the air deflector may include a distance attribute between the detection component and the air deflector. The detection device can be used to obtain its position on the wind deflector plate and the property of the cohesive force between the wind deflector to obtain the deformation parameter.

The degree of deformation is used to indicate the current deformation state of the wind deflector, for example, the deformation direction and/or the deformation amount.

Optionally, determining the degree of deformation at the location of the detection device includes:

Determining the deformation parameters of the air deflector according to the first electrical signal detected by the detection device; wherein the first electrical signal reflects the temperature of the air deflector at the location of the detection device;

According to the deformation parameters of the air deflector, the deformation direction and/or deformation amount of the air deflector are determined.

Here, the temperature of the wind deflector at the location of the detection device is reflected by the first electrical signal, so as to determine the deformation parameter of the wind deflector at the location according to the temperature of the wind deflector, thereby determining the deformation degree of the location. When the first electrical signal reflects the temperature of the wind deflector at the location where the detection device is located, the detection device may include a temperature sensor. The temperature value detected by the temperature sensor at its location is transmitted to the processing system in the form of a first electrical signal, so as to determine the deformation parameter of the wind deflector.

Further, determining the deformation parameter of the wind deflector includes: acquiring a difference between the temperature of the wind deflector reflected by the first electrical signal and a temperature threshold as the deformation parameter of the wind deflector.

That is, the deformation parameter K is obtained as follows:

K＝T ₁ -T _S

Among them, K is the deformation parameter, T ₁ is the temperature of the wind deflector reacted by the first electrical signal, and T _s is the temperature threshold.

Here, the temperature threshold T _s can be determined according to the current indoor ambient temperature, or can be determined according to the ambient temperature obtained in the test when the air deflector is in a non-deformed state, or the ambient temperature when the air deflector automatically returns to a non-deformed state after deformation. It is also possible to obtain a required temperature value as the temperature threshold T _s through big data, artificial intelligence, etc.

Further, according to the deformation parameters of the wind deflector, the deformation direction and/or deformation amount of the wind deflector are determined, including:

Determine the deformation direction of the wind deflector according to the positive and negative information of the deformation parameter; and/or,

Determine the deformation of the wind deflector according to the absolute value of the deformation parameter;

Wherein, when the deformation parameter is positive, the deformation direction of the air deflector is convex toward the direction away from the air guide; when the deformation parameter is negative, the deformation direction of the air deflector is concave toward the direction of the air guide.

In this way, the deformation direction is used to determine the direction in which the electromagnetic chuck applies the attractive force, and the amount of deformation is used to determine the magnitude of the electromagnetic chuck's applied attractive force. In this way, the strength of attraction of the electromagnetic chuck can be adjusted according to the degree of deformation of the wind deflector.

Specifically, determining the deformation amount of the wind deflector according to the absolute value of the deformation parameter may include: determining a plurality of absolute values corresponding to multiple deformation parameters one-to-one according to the correspondence between the absolute value of the deformation parameter and the deformation amount of the wind deflector. The determined deformation of the air deflector is used to determine the strength of attraction of the electromagnetic chuck, so as to reduce the gap between the air deflector and the air guide.

There is a positive correlation between the absolute value of the deformation parameter and the deformation of the wind deflector. That is, the greater the absolute value of the deformation parameter, the higher the degree of shape change of the wind deflector relative to the non-deformed state.

The correspondence between the absolute value of the deformation parameter and the deformation of the wind deflector can be obtained through a limited number of experiments. For example, for the absolute value of a deformation parameter (in this embodiment, the difference between the temperature of the air deflector at the location of the detection device and the temperature threshold), according to the same temperature threshold, when the air deflector is at different temperatures, that is When the difference between the temperature of the air deflector and the temperature threshold is different, the deformation of the air deflector is determined as the deformation corresponding to the difference, and the correspondence between the difference and the deformation is one-to-one way stored in the database. After the absolute value of the deformation parameter is determined according to the difference between the temperature of the air deflector and the temperature threshold, the difference corresponding to the absolute value of the deformation parameter and the corresponding deformation of the air deflector can be obtained by querying the database.

Among them, the deformation of the air deflector can be obtained in the following way: take the length direction of the air deflector in the non-deformed state as the horizontal direction; determine the maximum deformation distance of the deformation position of the air deflector along the vertical direction; according to the maximum deformation distance, Determines the amount of deformation at this deformation location.

In this way, when the air deflector is convexly deformed, the deformation of the position is indicated by the convex distance of the highest point of the convex part in the vertical direction; The inset distance of a point in the vertical direction represents the amount of deformation at that location. In this way, data processing and correspondence are facilitated in the correspondence between deformation variables and other parameters.

In some application scenarios, the degree of deformation of the air deflector can be calculated according to the temperature of the air deflector provided by the detection device and the temperature threshold. Here, the degree of deformation can be determined as follows:

H=a×K+b

Among them, H is the degree of deformation of the air deflector, K is the deformation parameter determined according to the difference between the temperature of the air deflector and the temperature threshold, a is the first adjustment factor related to the use attribute of the air conditioner, and b is the adjustment factor related to the use attribute of the air conditioner Second regulator.

Then, the absolute value of H is used to represent the deformation of the wind deflector at the location of the detection device, and the positive and negative information of H is used to represent the deformation direction of the wind deflector at the location of the detection device.

Further, the first adjustment factor a may be used to reflect the influence of the running time before the air conditioner is shut down on the deformation. There is a positive correlation between the value of the first adjustment factor a and the running time before the air conditioner is turned off. The longer the running time of the air conditioner before it shuts down, the longer it takes for the air sent from the air guide port of the air conditioner to have a large temperature difference with the current indoor ambient temperature to flow through the inner surface of the air guide plate, and the higher the degree of influence on the deformation of the air guide plate, the greater the impact on the air guide plate. The greater the deformation of the wind plate. The second adjustment factor b can also be used to reflect the influence of the running time before the air conditioner is shut down on the deformation.

Further, the second adjustment factor b can also be used to reflect the influence of the operating time of the electromagnetic chuck to exert the attractive force between the air guide plate and the air guide port on the deformation amount after the shutdown. There is a negative correlation between the value of the second adjustment factor b and the operating time during which the electromagnetic chuck exerts an attractive force between the wind deflector and the air deflector. The longer the operation time of the electromagnetic sucker exerting the attractive force between the air guide plate and the air guide port, the deformation of the air guide plate will reduce the deformation caused by the stress of itself under the influence of the electromagnetic sucker, so the guide The deformation of the wind plate is smaller.

Step S702, the processing system adjusts the attractive force of the electromagnetic chuck according to the degree of deformation, so as to reduce the gap between the air guide plate and the air guide port.

Optionally, adjusting the attractive force of the electromagnetic chuck according to the degree of deformation may also include:

According to the degree of deformation, the direction of the current of the electromagnetic chuck is adjusted one by one to a direction suitable for the degree of deformation.

In some application scenarios, according to the deformation parameters of the wind deflector provided by the detection device, the deformation direction of the wind deflector can be determined, so that the direction of attraction of the electromagnetic chuck can be adjusted by adjusting the current direction of the electromagnetic chuck, so that it is consistent with the The deformation direction of the air deflector is adapted so that the electromagnetic sucker applies an attractive force opposite to the deformation direction of the air deflector itself due to stress, so as to reduce the gap between the air deflector and the air guide opening.

For example, when the deformation direction of the air deflector is convex in the direction away from the air guide opening, adjust the current direction of the corresponding electromagnetic chuck to the first direction; when the deformation direction of the air guide plate is concave in the direction close to the air guide , adjust the current direction of the corresponding electromagnetic chuck to the second direction. Wherein, the first direction and the second direction represent opposite current directions.

Optionally, according to the degree of deformation, the attractive force of the electromagnetic chuck is adjusted, including:

According to the degree of deformation, the current intensity of the electromagnetic chuck is adjusted one by one to a size suitable for the degree of deformation.

Here, according to the degree of deformation, the current intensity of the electromagnetic chuck is adjusted one by one to a size suitable for the degree of deformation, including:

According to the corresponding relationship between the deformation amount and the attractive force, determine the required attractive force of the electromagnetic chuck;

The corresponding current intensity is determined according to the corresponding relationship between the attractive force required to be applied by the electromagnetic chuck and the current intensity.

Among them, there is a positive correlation between the deformation amount and the attractive force. That is, the greater the deformation amount of the deformation degree, the greater the attractive force that the electromagnetic chuck needs to apply.

The correspondence between the deformation amount and the attractive force can be obtained by a limited number of trials. For example, under the condition of the same temperature threshold, when the wind deflector has different deformations, obtain the magnitude of the attractive force required to suck it to the non-deformed state, and make the corresponding relationship between the deformation and the attractive force one-to-one stored in the database. After the deformation of the wind deflector is obtained, the attraction force corresponding to the deformation can be obtained by querying the database.

Further, there is a positive correlation between the attractive force required to be applied by the electromagnetic chuck and the current intensity. That is, the greater the attractive force required by the electromagnetic chuck, the greater the current required by the electromagnetic chuck to generate the attractive force.

The attraction of the electromagnetic chuck is the effect of the magnetic field generated by the coil inside it based on the steady current. According to the Biot-Savart law, the magnitude of the magnetic induction dB is determined by the current intensity and the number of turns of the coil. For the electromagnetic chuck, the number of turns of the coil is fixed, so the magnitude of its attractive force is proportional to the magnitude of the current. Therefore, the adjustment of the attraction force of the electromagnetic chuck can be realized by controlling the current intensity.

Optionally, the corresponding relationship between the attraction force of the electromagnetic chuck and the current intensity can be obtained through a limited number of experiments. For example, for an electromagnetic chuck with the same number of coil turns, different attractive forces can be obtained by passing currents of different intensities to it, and the corresponding relationship between the attractive force and the current intensity is stored in the in the database. After obtaining the attraction force required by the electromagnetic chuck, the current intensity corresponding to the magnitude of the attraction force can be obtained by querying the database.

With the wind deflector assembly provided in this embodiment, when the closing command is received, the deformation parameters of the wind deflector are obtained through the detection device to adjust the strength of the attraction force of the electromagnetic chuck, so that the electromagnetic chuck can be adjusted according to different deformation degrees. Attractive forces of different strengths are applied between the air deflector and the air guide to reduce the gap between the air deflector and the air guide. In this way, under the action of the attractive force with adjustable strength, the gap between the air guide plate and the air guide port is reduced, and the strength of the attractive force is adjusted during the process of restoring the shape of the air guide plate to a state without deformation, so as to improve the resistance to different The structure and the shape of the wind deflector under different use environments restore the adjustment effect.

Fig. 8 is a control method for the air deflector assembly provided by this embodiment, which is applied to an air conditioner having the above-mentioned air deflector assembly. The control method for the air deflector assembly can be executed in the air conditioner, or can be executed in the control terminal of the air conditioner, such as a remote control, an operation panel; it can also be executed in a server, such as a home cloud platform communicating with the air conditioner; Executed in a terminal device, such as a smart phone, a smart home appliance or a control terminal of a smart home system. In the embodiment of the present disclosure, the solution is described by taking the processing system of the wind deflector as the execution subject.

In step S801, in response to the shutdown command, the processing system receives the deformation parameters of the wind deflector provided by the detection device.

Step S802, when the deformation parameters of the air deflector meet the deformation conditions, the processing system determines the deformation amount at the location of the detection device according to the deformation parameters, so as to determine the current intensity required for electrification of the electromagnetic chuck corresponding to the detection device, thereby adjusting The magnetic attraction force of the magnetic chuck.

Step S803, when the deformation parameter of the air deflector does not satisfy the deformation condition, the processing system stops the adjustment of the attraction force to the electromagnetic chuck.

In step S804, the processing system proceeds to step S802 if the deformation parameter of the new cycle meets the deformation condition after receiving and detecting the deformation parameters of the wind deflector at preset periodic intervals; otherwise, proceeds to step S803.

Here, the deformation condition is used to indicate that at the moment of shutdown, the position of the air deflector where the detection device is located is deformed, so that the gap between the air deflector and the air deflector becomes larger, and it is necessary to use an electromagnetic chuck to place the air deflector between the air deflector and the air deflector. Apply an attractive force, thereby reducing the gap between the air guide opening and the air deflector. Further, the deformation condition includes: the deformation amount represented by the deformation parameter of the wind deflector is greater than a preset deformation amount.

In this embodiment, the deformation direction of the air deflector may be determined according to the operating mode of the air conditioner before shutdown. For example, if the air conditioner is running in the cooling mode before shutting down, then determine the position where the deflector is deformed, and the deformation direction is inward toward the direction of the air guide opening; position, and its deformation direction is outwardly convex away from the air guide port.

When the air conditioner receives the shutdown command, the air deflector runs closed, and the temperature at its location is obtained through the detection device (in this embodiment, a temperature sensor) arranged on the air deflector, and is transmitted to the processing system. The temperature signal obtains the deformation parameter of the position of the detection device, and according to the corresponding relationship between the deformation parameter and the deformation amount, calculates the degree of deformation of the position of the detection device (in this embodiment at least including the deformation amount), and further according to the deformation According to the corresponding relationship between the variable and the attractive force, the required attractive force of the electromagnetic chuck corresponding to the detection device is calculated; finally, according to the corresponding relationship between the attractive force and the current intensity, the current intensity for electrifying the electromagnetic chuck is calculated. And the electromagnetic chuck is powered according to the current intensity according to the control power supply, so that the control of the attraction force of the electromagnetic chuck is realized by controlling the magnitude of the current.

With the air deflector assembly provided in this embodiment, when the closing command is received, the deformation parameters of the air deflector are obtained through the detection device, and after the deformation of the air deflector is determined, the strength of attraction of the electromagnetic chuck is adjusted to realize the With different degrees of deformation, the electromagnetic chuck exerts attractive forces of different strengths between the air guide plate and the air guide port, so as to reduce the gap between the air guide plate and the air guide port. In this way, under the action of the attractive force with adjustable strength, the gap between the air guide plate and the air guide port is reduced, and the strength of the attractive force is adjusted during the process of restoring the shape of the air guide plate to a state without deformation, so as to improve the resistance to different The structure and the shape of the wind deflector under different use environments restore the adjustment effect.
