The embodiment of the present application also provides a control method of an air conditioner, which is applied to control the above-mentioned air conditioner

Referring to FIG. 4 , an embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, the control method of the air conditioner includes:

Step S10, obtaining the characteristic parameters of the pipe diameter of the fresh air pipe installed in the air conditioner;

The pipe diameter characteristic parameter is a characteristic parameter specifically representing the pipe diameter of the fresh air pipe. In this embodiment, the pipe diameter refers to the outer diameter of the new air pipe (that is, the size that matches the wall hole on the wall); in other embodiments, the pipe diameter can also refer to the inner diameter of the new air pipe (that is, The size of the fresh air circulation channel in the fresh air pipe).

In this embodiment, the diameter characteristic parameter includes the pipe diameter type. Specifically, the pipe diameter type may specifically include a first type and a second type, and the diameter of the fresh air pipe corresponding to the first type is larger than the pipe diameter of the fresh air pipe corresponding to the second type. The pipe diameter of the fresh air pipe corresponding to each type may be a fixed pipe diameter value or within a certain pipe diameter range. In addition, in other embodiments, more types of pipe diameter can be set according to the actual situation, such as the first type, the second type, and the third type, etc., and the pipe diameters of the fresh air pipes corresponding to each type decrease in turn.

In addition, in other embodiments, the pipe diameter characteristic parameter may also include a pipe diameter value of the new air pipe.

The characteristic parameters of the pipe diameter here can be obtained by obtaining the parameters input by the user. For example, when the user inputs that the installation mode of the new air duct is the reaming mode, it can be determined that the pipe diameter type is the first type, and the user enters whether the installation mode of the new air duct is not In the reaming mode, it can be determined that the pipe diameter type is the second type. In addition, the characteristic parameters of the pipe diameter can also be obtained by detecting the installation state of the installed fresh air pipe through the detection module installed on the air conditioner, for example, by obtaining the signal output by the above-mentioned travel switch or by obtaining the installation hole of the fresh air pipe through the camera. images etc.

Step S20, determining the speed control parameters of the fresh air fan of the air conditioner according to the pipe diameter characteristic parameters; different pipe diameter characteristic parameters correspond to different speed control parameters;

The type of the speed control parameter here may include an adjustment parameter of the speed of the fresh air fan (such as increasing or decreasing the speed, an adjustment value of the speed, etc.) or a target speed value of the fresh air fan to be operated.

The speed control parameters corresponding to different pipe diameter characteristic parameters have different values. The speed of the fresh air fan corresponding to the speed control parameter decreases with the increase of the pipe diameter of the fresh air pipe corresponding to the pipe diameter characteristic parameter; The diameter of the air duct decreases and shows an increasing trend.

Specifically, the corresponding relationship between the pipe diameter characteristic parameter and the rotational speed control parameter may be preset, and the corresponding relationship may be a calculation formula, a mapping relationship, and the like. Based on this correspondence, the target speed value of the fresh air fan can be calculated through the characteristic parameters of the pipe diameter as the speed control parameter; the mapping table can also be queried through the characteristic parameters of the pipe diameter, and the matched speed adjustment parameter or target speed value can be used as the speed control parameter. parameter.

Wherein, the corresponding relationship between the pipe diameter characteristic parameter and the rotational speed control parameter can be preset as a fixed one, or more than one can be preset. When there is more than one corresponding relationship between the pipe diameter characteristic parameter and the rotational speed control parameter, the current operating parameters of the air conditioner (such as the air outlet angle, the temperature of the fresh air heat exchanger, etc.) or the indoor environment parameters (such as Indoor air pressure, etc.) determine one of the more than one correspondences as the target correspondence, and determine the speed control parameter corresponding to the current pipe diameter characteristic parameter based on the target correspondence.

Step S30, controlling the operation of the fresh air fan according to the rotational speed control parameter.

When the speed control parameter is the target speed value of the fresh air fan, the fresh air fan is controlled to run at the target speed value; when the speed control parameter is the speed adjustment parameter of the fresh air fan, the speed of the fresh air fan is increased or decreased according to the speed adjustment parameter.

An air conditioner control method proposed in the embodiment of the present application, the method is adapted to adjust the speed of the fresh air fan by the diameter characteristic parameters of the fresh air pipe of the air conditioner, and control the speed of the fresh air fan corresponding to different pipe diameter characteristic parameters The parameters are different, so that the running speed of the fresh air fan can no longer run according to the preset fixed speed, but can adapt to the change of the diameter of the fresh air pipe, which can avoid the fan no matter how the installation scene of the fresh air pipe changes. Excessive operating speed leads to excessive operating noise while avoiding insufficient fresh air volume due to too low fan operating speed, so that the air conditioner can increase the fresh air volume for users while creating a low-noise environment and improve indoor user comfort.

Further, another embodiment of the air conditioner control method of the present application is proposed based on the above embodiments. In this embodiment, the characteristic parameters of the pipe diameter include the pipe diameter type. Referring to FIG. 5, the step S20 includes:

Step S21, when the pipe diameter type is the first type, determine the first target speed as the speed control parameter;

Step S22, when the pipe diameter type is the second type, determine a second target speed as the speed control parameter;

Specifically, in this embodiment, the fresh air blower has multiple operating wind speeds, and the fresh air blower has different operating wind speeds, so the first target speed and the second target speed are different. Both the first target speed and the second target speed show an increasing trend with the increase of the operating wind gear; conversely, both the first target speed and the second target speed show a decreasing trend with the decrease of the running wind gear. Based on this, the current operating wind gear of the fresh air fan can be determined, and the first target speed corresponding to the current first type of fresh air pipe or the second target speed corresponding to the current second type of fresh air pipe can be determined based on the current operating wind of the fresh air fan .

Further, the rotational speed difference between the first target rotational speed and the second target rotational speed tends to increase as the operating gear of the fresh air fan increases; conversely, the first target rotational speed and the second target rotational speed The speed difference between them shows a decreasing trend as the operating wind gear of the fresh air fan decreases. In this embodiment, the rotational speed difference is specifically the absolute value of the difference between the first target rotational speed and the second target rotational speed. In other embodiments, the rotational speed difference may be the difference between the first target rotational speed and the second target rotational speed. Based on this, it can ensure that the fresh air fan can accurately reach the user's comfort state when it runs at the target speed corresponding to the current pipe diameter type.

In this embodiment, a specific application is used to describe the first target speed corresponding to the first type of fresh air pipe, the second target speed corresponding to the second type of fresh air pipe, and the first The numerical relationship between the target speed and the speed difference between the second target speed is as follows:

运行风档 run windshield	第二目标转速 Second target speed	第一目标转速 first target speed	转速差 speed difference
静音档 silent file	1000 1000	900 900	100 100
中风档 stroke gear	1200 1200	1100 1100	100 100
高风档 high wind speed	1600 1600	1450 1450	150 150
强劲档 strong file	2000 2000	1800 1800	200 200

Among them, the wind power of the silent gear, the middle wind gear, the high wind gear and the strong gear increases in turn.

In this embodiment, when the fresh air duct used by the air conditioner is a large-diameter type, the fresh air fan adopts a smaller operating speed; when the fresh air duct used by the air conditioner is a small-diameter type, the fresh air fan adopts a larger The operating speed of the air conditioner can ensure that the air conditioner has a relatively low operating noise and a large fresh air volume, so as to ensure that the comfort of indoor users can be effectively improved when the air conditioner introduces fresh air.

Further, based on any of the above embodiments, another embodiment of the control method for the air conditioner of the present application is proposed. In this embodiment, referring to FIG. 6, step S10 includes:

Step S11, detecting the installation depth of the new air duct in the installation channel of the air conditioner;

Specifically, the detection data of the detection modules arranged in the installation channel are acquired, and the installation depth here is determined based on the detection data. The type of the detection module can be set according to actual needs. In this embodiment, the detection module is a travel switch; in other embodiments, the detection module can also be a pressure sensor or the like.

The installation depth here can be a specific value or a range of values.

Step S12, determining the diameter characteristic parameters of the new air duct according to the installation depth; wherein, the installation depths of the new air ducts with different pipe diameter characteristic parameters in the installation channel are different.

Different installation depths correspond to different pipe diameter characteristic parameters. Specifically, based on the structure of the installation part of the fresh air pipe with different characteristic parameters or the installation method on the fresh air module is different, the corresponding relationship such as the calculation formula and the mapping relationship between the installation depth and the characteristic parameter of the pipe diameter can be preset. Based on the corresponding relationship, the characteristic parameter of the pipe diameter corresponding to the current installation depth can be determined. For example, when the installation depth is the depth value, the diameter value of the new air duct can be calculated through the depth value as the pipe diameter characteristic parameter; for another example, based on the mapping relationship, the pipe diameter type or pipe diameter value mapped by the installation depth can be used as Pipe diameter characteristic parameters, etc.

In this embodiment, the pipe diameter characteristic parameter includes a pipe diameter type, and the step of determining the pipe diameter characteristic parameter of the new air duct according to the installation depth includes: when the installation depth is greater than a set depth, Determine the first type as the pipe diameter type; when the installation depth is less than the set depth, determine the second type as the pipe diameter type; the pipe diameter of the new air pipe corresponding to the first type is larger than the set depth The diameter of the fresh air pipe corresponding to the second type.

In this embodiment, the characteristic parameters of the pipe diameter of the new air duct are characterized by detecting the installation depth of the installation pipe, so that the air conditioner can automatically recognize the characteristic parameters of the pipe diameter when the new air duct is installed, and adapt to the The characteristic parameter of the pipe diameter regulates the running speed of the fresh air fan without user operation, so that the air conditioner can intelligently realize the operation noise is small and there is a large fresh air volume.

Further, in this embodiment, the installation passage has an installation opening for the fresh air pipe to be inserted into, and a travel switch is provided in the installation passage, and fresh air pipes of different pipe diameters allow different lengths to be inserted into the installation opening. , to trigger the travel switch to output different position signals, the step of obtaining the installation depth of the new air duct in the installation channel of the air conditioner includes: obtaining the position signal output by the travel switch; according to the position signal to determine the installation depth.

The position signal is specifically the closing signal or opening signal of the travel switch. Different position signals correspond to different installation depths.

Specifically, in this embodiment, when the position signal is the first position signal, it is determined that the installation depth is greater than the set depth; when the position signal is the second position signal, the installation depth is determined less than the set depth. Based on this, when the position signal is the first position signal, it is determined that the air conditioner is currently installed with the first type of fresh air duct; when the position signal is the second position signal, it is determined that the air conditioner is currently installed with the second type new air duct.

In addition, in other embodiments, when the installation depth is greater than the set depth, the second type is determined to be the pipe diameter type; when the installation depth is less than the set depth, the first type is determined to be the pipe diameter type . Based on this, when the position signal is the second position signal, it is determined that the air conditioner is currently installed with the first type of fresh air duct; when the position signal is the first position signal, it is determined that the air conditioner is currently installed with the second type new air duct.

In this embodiment, by setting a limit switch in the installation channel of the air conditioner, based on the position signal output by the limit switch, the automatic identification of the diameter characteristics of the fresh air pipe installed in the air conditioner is realized, and the intelligence of the fresh air control of the air conditioner is improved. degree.

Further, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, referring to FIG. 7, step S10 includes:

Step S101, controlling the fresh air fan to operate at a target wind speed and detecting the operating power of the fresh air fan;

In this embodiment, the target wind gear may be the operating gear of the fresh air fan set by the user, may also be a fixed gear set by default for the air conditioner, or may be a gear determined by the air conditioner based on indoor environment monitoring parameters. Wherein, the fresh air blower can have one windshield or more than one windshield.

The operating power of the fresh air fan here specifically refers to the real-time power currently output by the motor shaft of the fresh air fan. When the fresh air fan maintains the operation of the target windshield, the real-time detected power of the motor shaft is used as the operating power here.

Step S102, determining the characteristic parameters of the pipe diameter according to the operating power; different operating powers correspond to different characteristic parameters of the pipe diameter.

When the fresh air fan operates at a fixed operating wind speed, the operating power of the fresh air fan will be different if the characteristic parameters of the diameter of the fresh air pipe installed in the air conditioner are different. Specifically, the diameter of the fresh air duct corresponding to the characteristic parameter of the pipe diameter increases with the increase of the operating power; conversely, the diameter of the fresh air duct corresponding to the characteristic parameter of the pipe diameter decreases with the increase of the operating power showing a decreasing trend. Based on this, the corresponding relationship between the operating power and the characteristic parameters of the pipe diameter can be established in advance, and based on the corresponding relationship, the characteristic parameters of the pipe diameter here can be obtained by calculating the operating power or querying the mapping relationship. Wherein, the corresponding relationship here can be obtained based on the target wind gear, and there are different corresponding relationships between the operating power and the pipe diameter characteristic parameters under different target wind gears.

In this embodiment, the characteristic parameter of the diameter of the fresh air pipe installed in the air conditioner is obtained through the operating power of the fresh air blower when it operates at the target wind speed, so that the air conditioner can realize the detection of the fresh air pipe without setting up an additional detection module. Automatic identification of pipe diameter characteristics, so that without user operation, the air conditioner can intelligently achieve low operating noise and large fresh air volume.

Further, in this embodiment, the pipe diameter characteristic parameter includes pipe diameter type, and the step of determining the pipe diameter characteristic parameter according to the operating power includes: determining the deviation between the operating power and the target power; The target power is the set power corresponding to the first type of new air duct; when the deviation is less than or equal to the set power deviation value, it is determined that the first type is the pipe diameter type; when the deviation When the amount is greater than the set power deviation value, it is determined that the second type is the pipe diameter type; the pipe diameter of the fresh air pipe corresponding to the first type is different from the fresh air pipe diameter corresponding to the second type The diameter of the pipe, the diameter of the fresh air pipe corresponding to the first type is different from the diameter of the fresh air pipe corresponding to the second type, and the operating parameters of the fresh air fan when operating at the target wind speed is the parameter corresponding to the first type.

In this embodiment, the deviation is specifically the absolute value of the difference between the operating power and the target power. In other embodiments, the deviation can also be the difference between the operating power and the target power.

The set power deviation value can be set according to the actual situation. In this embodiment, the set power deviation value is 0.5W; in other embodiments, the set power deviation value can also be 1W, 0.8W, 0.3W, etc.

Here, the operating parameters of the fresh air fan when operating at the target wind speed include the operating parameters and operating power of the motor.

In this embodiment, the diameter of the fresh air pipe corresponding to the first type is larger than the diameter of the fresh air pipe corresponding to the second type. Specifically, the first type with a larger pipe diameter is set as the preset pipe diameter type, and the set power corresponding to the first type of fresh air pipe under the current operating wind gear of the fresh air fan is taken as the target power here. Based on this, when the deviation between the actual operating power of the fresh air fan and the target power is small, it can be considered that the diameter type of the fresh air pipe installed in the air conditioner is the first type with a larger pipe diameter corresponding to the target power; When the deviation between the actual operating power and the target power is large, it can be considered that the diameter type of the fresh air pipe installed on the air conditioner is not the first type with the largest pipe diameter corresponding to the target power, and it can be determined that the air conditioner installed The pipe diameter type of the fresh air pipe is a second type different from the first type.

For example, the operating parameters and power of the motor are first set to the parameters under the expansion mode (that is, the fresh air pipe with a larger diameter is installed), and it is judged whether the current fresh air ventilation is turned on. If it is turned on, the current operating power is recorded to determine the current fresh air power and The difference of the target power, if the difference is greater than 0 and less than 0.5W, it is determined that it is in the reaming mode, and the fresh air fan operates according to the operating parameters corresponding to the reaming mode, if the difference is greater than 0.5W, that is, the fresh air installation mode is no reaming mode (that is, installing a fresh air pipe with a smaller diameter), the fresh air fan operates according to the operating parameters corresponding to the non-reaming mode.

Specifically, in this embodiment, the fresh air fan has different operating wind gears, before the step of determining the deviation between the operating power and the target power, it also includes: determining the target power according to the target wind gear; Wherein, different target wind gears correspond to different target powers. Specifically, the target power tends to increase as the target wind gear increases; conversely, the target power tends to decrease as the target wind gear decreases.

In this embodiment, a specific application is used to illustrate the target power corresponding to fresh air ducts of different diameters and types under different target windshields, as shown in the following table:

目标风档 target windshield	目标功率A（W） Target power A (W)	目标功率B（W） Target power B (W)
静音档 silent file	6.5（1000rpm） 6.5 (1000rpm)	7.5（900rpm） 7.5 (900rpm)
中风档 stroke gear	8（1200rpm） 8 (1200rpm)	9（1100rpm） 9 (1100rpm)
高风档 high wind speed	10.5（1600rpm） 10.5 (1600rpm)	12（1450rpm） 12 (1450rpm)
强劲档 strong file	13（2000rpm） 13 (2000rpm)	15（1800rpm） 15 (1800rpm)

Wherein, the silent gear, the medium wind gear, the high wind gear and the strong wind gear are the wind gears which increase in sequence.

The above target power A is the corresponding target power of the first type and the second type corresponding to the smaller diameter type of the fresh air duct (that is, the installation mode of the fresh air duct is the non-reaming mode); the target power B is the target power corresponding to the larger diameter type of the fresh air duct corresponding to the first type and the second type (that is, the installation mode of the fresh air duct is the expansion mode). In this embodiment, the diameter of the fresh air pipe corresponding to the first type is greater than the diameter of the fresh air pipe corresponding to the second type, then the corresponding power B can be determined as the target power based on the target wind speed, for example, the target wind speed The target power is 15W when it is strong, and the target power is 9W when the target wind is medium.

In this embodiment, when the types of fresh air ducts include the first type and the second type, the fresh air fans are first operated with the set parameters corresponding to one of the preset diameter types of fresh air ducts, based on the Detect the relationship between the deviation between the operating power of the fresh air fan and the target power corresponding to the preset pipe diameter type and the set power deviation value, and check whether the type of fresh air pipe currently installed on the air conditioner is the same as the preset pipe diameter type Characterize, so as to accurately determine the diameter type of the fresh air pipe installed in the current air conditioner based on the size relationship, and realize that the air conditioner can adapt to the pipe diameter type of the fresh air pipe to achieve precise control of the speed of the fresh air fan, thereby further ensuring the air conditioner There is a large amount of fresh air while the operating noise of the device is low. Among them, different target wind gears correspond to different target powers, so that the fresh air fan can accurately identify the diameter type of the fresh air pipe currently installed on the air conditioner regardless of the wind speed when the fresh air fan is running, so as to realize the speed control of the fresh air fan. precise control to improve indoor user comfort.

In other embodiments, the second type with a smaller pipe diameter can also be set as the preset pipe diameter type, and the set power corresponding to the second type of fresh air pipe under the current operating wind gear of the fresh air fan is used as the target power. Based on this, determine the deviation between the operating power and the target power; the target power is the preset parameter corresponding to the second type of fresh air duct; when the deviation is less than or equal to the set power deviation value, determine The second type is the pipe diameter type; when the deviation amount is greater than the set power deviation value, it is determined that the first type is the pipe diameter type.

Based on the above two embodiments, define the acquisition method of the pipe diameter characteristic parameters corresponding to the relevant embodiments in steps S11 to S12 as the first acquisition method, and define the acquisition method of the pipe diameter characteristic parameters corresponding to the relevant embodiments in steps S101 to S102 as In the second acquisition mode, one of the first acquisition mode and the second acquisition mode may be determined based on preset rules to obtain the characteristic parameters of the pipe diameter. For example, the user setting parameters can be obtained, and one of the first and second acquisition methods can be determined based on the user setting parameters to obtain the characteristic parameters of the pipe diameter; as another example, the detection of the installation depth of the fresh air pipe in the fresh air module can be detected The installation state of the module (specifically, it can be identified through the control device to detect whether there is a detection signal input by the detection module). If the installation state is that the detection module for detecting the installation depth of the fresh air duct has been installed, follow steps S11 and S12 and their detailed plans Obtain the characteristic parameters of the pipe diameter; if the installation state is that the detection module for detecting the installation depth of the fresh air pipe is not installed, obtain the characteristic parameters of the pipe diameter according to steps S101 and S102 and their refinement schemes.

In addition, when there is a travel switch, when the installation depth is determined to be greater than the set depth according to step S11, the use time of the air conditioner can be obtained (specifically, it will be counted from the first time it is activated after leaving the factory). If the use time is greater than the set time, you can According to step S101 and step S102 and its refinement scheme, obtain the characteristic parameters of pipe diameter; if the use time is less than or equal to the set duration, obtain the characteristic parameters of pipe diameter according to step S12 and its refinement scheme. Based on this, it can effectively avoid the failure of the characterization of the characteristic parameters of the pipe diameter due to long-term pressure fatigue damage of the travel switch, thereby effectively improving the accuracy of the obtained characteristic parameters of the pipe diameter, so as to achieve precise control of the fresh air fan, and to improve indoor User comfort.
