Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. Background Art

[0002] With the continuous improvement of people's living standards, air conditioners are more and more widely used, and the functions of air conditioners are also more and more diversified. At present, most air conditioners have a fresh air function, which generally has a fresh air pipe passing through a wall hole and is connected to the outside through the fresh air pipe to introduce fresh outdoor air into the room through the fresh air pipe. Among them, there are two installation modes for the fresh air pipe, one is the reaming mode, and the other is the non-reaming mode. The fresh air pipe diameter in the reaming mode is larger, while the fresh air pipe diameter in the non-reaming mode is smaller.

[0003] However, before leaving the factory, the operating speed of the fresh air fan is generally fixedly set according to one of the reaming mode and the non-reaming mode. When the subsequent installation mode is inconsistent with the preset mode before leaving the factory, if the preset speed of the fresh air fan is too large, it will cause excessive noise in the fresh air air conditioner; if the preset speed of the fresh air fan is too small, it will cause insufficient fresh air volume in the fresh air air conditioner, affecting the comfort of indoor users. Summary of the Invention

The step of obtaining the installation depth of the fresh air duct in the installation channel of the air conditioner includes:

[0023] Obtain the position signal output by the travel switch;

[0024] Determine the installation depth according to the position signal.

[0025] Optionally, determining the installation depth according to the position signal includes:

[0026] When the position signal is the first position signal, determine that the installation depth is greater than the set depth;

[0027] When the position signal is the second position signal, determine that the installation depth is less than the set depth.

[0028] Optionally, the step of obtaining the pipe diameter characteristic parameters of the fresh air duct for air conditioner installation includes:

The rotation speed control parameters of the fresh air fan corresponding to different pipe diameter characteristic parameters are different. It can be realized that the operating rotation speed of the fresh air fan no longer operates at a preset fixed rotation speed, but can adapt to the change of the pipe diameter of the fresh air pipe. It can be realized that no matter how the installation scenario of the fresh air pipe changes, it is possible to avoid the excessive operating rotation speed of the fan resulting in excessive operating noise and at the same time avoid the too small operating rotation speed of the fan resulting in insufficient fresh air volume. Thus, while the air conditioner provides a large amount of fresh air for users, it creates a low-noise environment and improves the comfort of indoor users. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The realization of the object of the present invention, functional features and advantages will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0054] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0055] The main solution of the embodiment of the present invention is: obtaining the pipe diameter characteristic parameters of the fresh air duct installed in the air conditioner; 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; controlling the operation of the fresh air fan according to the speed control parameters.

[0056] In the prior art, generally, the operating speed of the fresh air fan is fixedly set in one of the reaming mode and the non-reaming mode before the fresh air fan leaves the factory. This results in that when the subsequent installation mode is inconsistent with the preset mode before leaving the factory, if the preset speed of the fresh air fan is too large, the noise of the fresh air conditioner will be too loud, and if the preset speed of the fresh air fan is too small, the fresh air volume of the fresh air conditioner will be insufficient, affecting the comfort of indoor users.

[0057] The present invention provides the above solution, aiming to achieve a large fresh air volume for users while creating a low-noise environment and improving the comfort of indoor users.

[0058] An embodiment of the present invention provides an air conditioner. In this embodiment, the air conditioner is a wall-mounted air conditioner. In other embodiments, the air conditioner can also be a cabinet air conditioner, a mobile air conditioner, etc.

[0059] In the embodiment of the present invention, referring to Figure 1 and Figure 2 , the air conditioner includes a fresh air module 1 and a control device. The fresh air module 1 is provided with a fresh air duct. A fresh air fan 11 is arranged in the fresh air duct. The fresh air fan 11 is used to drive outdoor fresh air to flow through the fresh air duct and enter the indoor environment. The fresh air fan 11 is connected to the control device, and the control device can be used to control the operation of the fresh air fan 11.

[0060] The fresh air module 1 is provided with an installation channel for installing the fresh air duct 2. The installation channel has an installation opening for the fresh air duct 2 to be inserted, so that the fresh air duct 2 can be detachably installed on the fresh air module 1. Specifically, the fresh air duct 2 is provided with an installation part, and the installation part includes a clamping part and a plugging part adapted to the installation channel. When the fresh air duct 2 is installed on the fresh air module 1, the plugging part is inserted into the installation channel, and the clamping part is clamped at the installation opening to limit the installation depth of the plugging part in the installation channel.

[0061] As Figure 2As shown in the figure, a travel switch 12 and a triggering component 13 for triggering the travel switch 12 are provided in the installation channel. The distance between the triggering component 13 and the installation port is a set depth. When fresh air ducts 2 of different pipe diameter types are installed in the installation channel, their positions relative to the triggering component 13 are different, so the triggering component 13 triggers the travel switch 12 to output different position signals. The travel switch 12 is connected to the control device, and the control device can obtain the signal output by the travel switch 12 to obtain the pipe diameter type of the fresh air duct 2 installed in the air conditioner.

[0062] Among them, as Figure 2 (a) shows, when the triggering component 13 is in the first position, pressing the travel switch 12 causes the travel switch 12 to output a first position signal; as Figure 2 (b) shows, when the triggering component 13 is in the second position, it does not touch the travel switch 12, causing the travel switch 12 to output a second position signal. The distance between the first position and the installation port is greater than the set depth, and the distance between the second position and the installation port is less than the set depth. Based on this, fresh air ducts 2 of different pipe diameter types can be set with different allowable insertion lengths into the fresh air duct (i.e., the length of the above-mentioned insertion part), so as to realize the travel switch 12 outputting signals to characterize fresh air ducts 2 of different pipe diameter types.

[0063] Among them, the type of the fresh air duct 2 installed on the fresh air module 1 can be selected according to the actual needs of the user. Specifically, when the user selects the reaming mode as the installation mode of the fresh air duct 2, a fresh air duct 2 with a larger pipe diameter (the first type) can be installed on the fresh air module 1; when the user selects the non-reaming mode as the installation mode of the fresh air duct 2, a fresh air duct 2 with a smaller pipe diameter (the second type) can be installed on the fresh air module 1.

[0064] In this embodiment, as Figure 1 (a) and Figure 2 (a) show, when the fresh air duct 2 of the first type is installed in the installation channel, the triggering component 13 moves to the first position to trigger the travel switch 12 to output a first position signal; as Figure 1 (b) and Figure 2 (b) show, when the fresh air duct 2 of the second type is installed in the installation channel, it is located at the second position with the triggering component 13 to trigger the travel switch 12 to output a second position signal; the pipe diameter of the fresh air duct 2 corresponding to the first type is larger than the pipe diameter of the fresh air duct 2 corresponding to the second type. Specifically, define the set depth between the triggering component 13 and the installation port as H1, the length of the insertion part of the fresh air duct 2 of the first type (i.e., the installation depth in the installation channel) as H2, and the length of the insertion part of the fresh air duct 2 of the second type (i.e., the installation depth in the installation channel) as H3, then H2 > H1, H3 < H1.

[0065] In other embodiments, when the fresh air duct 2 of the first type is installed in the installation channel, the triggering component 13 moves to the second position to trigger the travel switch 12 to output a second position signal; when the fresh air duct 2 of the second type is installed in the installation channel, the triggering component 13 is located at the first position to trigger the travel switch 12 to output a first position signal; the diameter of the fresh air duct 2 corresponding to the first type is greater than the diameter of the fresh air duct 2 corresponding to the second type. Specifically, the set depth between the triggering component 13 and the installation opening is defined as H1, the length of the insertion part of the fresh air duct 2 of the first type (i.e., the installation depth in the installation channel) is H2, and the length of the insertion part of the fresh air duct 2 of the second type (i.e., the installation depth in the installation channel) is H3, then H2 < H1, H3 > H1.

[0066] Specifically, in the embodiments of the present invention, referring to Figure 3 , the above-mentioned fresh air fan 11 and travel switch 12 are both connected to the control device of the air conditioner. The control device includes: a processor 1001 (such as a CPU), a memory 1002, etc. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0067] Those skilled in the art can understand that Figure 3 the device structure shown in

[0068] does not constitute a limitation to the device, and may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements. Figure 3 As shown in Figure 3 , the memory 1002, as a computer-readable storage medium, may include a control program for the air conditioner. In the device shown in

[0069] , the processor 1001 can be used to call the control program for the air conditioner stored in the memory 1002 and execute the relevant step operations of the control method for the air conditioner in the following embodiments.

[0070] The embodiments of the present invention further provide a control method for an air conditioner, which is applied to control the above-mentioned air conditioner Figure 4 . Referring to

[0071] , an embodiment of the control method for the air conditioner of the present application is proposed. In this embodiment, the control method for the air conditioner includes:

[0072] The pipe diameter characteristic parameter specifically characterizes the characteristic parameter of the pipe diameter of the fresh air duct. In this embodiment, the pipe diameter refers to the outer diameter of the fresh air duct (i.e., the dimension that fits the wall hole on the wall); in other embodiments, the pipe diameter may also refer to the inner diameter of the fresh air duct (i.e., the dimension of the fresh air flow passage inside the fresh air duct).

[0073] In this embodiment, the pipe 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 pipe diameter of the fresh air duct corresponding to the first type is larger than that of the fresh air duct corresponding to the second type. The pipe diameter of the fresh air duct corresponding to each type may be a fixed pipe diameter value or within a certain pipe diameter range. In addition, in other embodiments, the pipe diameter type may also be set to more types according to actual situations, such as the first type, the second type, and the third type, etc., and the pipe diameters of the fresh air ducts corresponding to each type decrease in sequence.

[0074] In addition, in other embodiments, the pipe diameter characteristic parameter may also include the pipe diameter value of the fresh air duct.

[0075] The pipe diameter characteristic parameter here can be obtained by obtaining the parameter input by the user. For example, when the user inputs that the installation mode of the fresh air duct is the reaming mode, it can be determined that the pipe diameter type is the first type, and when the user inputs that the installation mode of the fresh air duct is the non-reaming mode, it can be determined that the pipe diameter type is the second type. In addition, the pipe diameter characteristic parameter can also be obtained by the detection module set on the air conditioner to detect the installation state of the installed fresh air duct, such as by obtaining the signal output by the above-mentioned travel switch or by obtaining the image of the installation hole of the fresh air duct through a camera, etc.

[0076] Step S20, determine the speed control parameter of the fresh air fan of the air conditioner according to the pipe diameter characteristic parameter; different pipe diameter characteristic parameters correspond to different speed control parameters;

[0077] The type of the speed control parameter here may include the adjustment parameter of the fresh air fan speed (such as increasing the speed or decreasing the speed, the speed adjustment value, etc.) or the target speed value required for the operation of the fresh air fan, etc.

[0078] 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 as the pipe diameter of the fresh air duct corresponding to the pipe diameter characteristic parameter increases; conversely, the speed of the fresh air fan corresponding to the speed control parameter increases as the pipe diameter of the fresh air duct corresponding to the pipe diameter characteristic parameter decreases.

[0079] Specifically, the corresponding relationship between the pipe diameter characteristic parameter and the rotational speed control parameter can be preset. The corresponding relationship can be a calculation formula, a mapping relationship, etc. Based on this corresponding relationship, the target rotational speed value of the fresh air fan operation can be calculated through the pipe diameter characteristic parameter as the rotational speed control parameter; or the mapping table can be queried through the pipe diameter characteristic parameter, and the matched rotational speed adjustment parameter or target rotational speed value can be used as the rotational speed control parameter.

[0080] Among them, the corresponding relationship between the pipe diameter characteristic parameter and the rotational speed control parameter can be preset to be one, or more than one can be preset. When there are more than one corresponding relationships 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 the indoor air pressure, etc.) can be used to determine one of them as the target corresponding relationship from the more than one corresponding relationships, and the rotational speed control parameter corresponding to the current pipe diameter characteristic parameter can be determined based on the target corresponding relationship.

[0081] Step S30, control the operation of the fresh air fan according to the rotational speed control parameter.

[0082] When the rotational speed control parameter is the target rotational speed value of the fresh air fan, control the fresh air fan to operate at the target rotational speed value; when the rotational speed control parameter is the rotational speed adjustment parameter of the fresh air fan, increase or decrease the rotational speed of the fresh air fan according to the rotational speed adjustment parameter.

[0083] A control method of an air conditioner proposed in an embodiment of the present invention is adapted to regulate the rotational speed of a fresh air fan according to the pipe diameter characteristic parameter of the fresh air pipe of the air conditioner. Different pipe diameter characteristic parameters correspond to different rotational speed control parameters of the fresh air fan, and it can be realized that the operating rotational speed of the fresh air fan no longer operates at a preset fixed rotational speed, but can adapt to the change of the pipe diameter of the fresh air pipe. It can be realized that no matter how the installation scenario of the fresh air pipe changes, it is possible to avoid the excessive operating rotational speed of the fan resulting in excessive operating noise and at the same time avoid the too small operating rotational speed of the fan resulting in insufficient fresh air volume, so as to realize that the air conditioner provides a large fresh air volume for users while creating a low-noise environment and improving the comfort of indoor users.

[0084] Further, based on the above embodiment, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, the pipe diameter characteristic parameter includes the pipe diameter type. Referring to Figure 5 , the step S20 includes:

[0085] Step S21, when the pipe diameter type is the first type, determine the first target rotational speed as the rotational speed control parameter;

[0086] Step S22, when the pipe diameter type is the second type, determine the second target rotational speed as the rotational speed control parameter;

[0087] The pipe diameter of the fresh air duct corresponding to the first type is larger than that of the fresh air duct corresponding to the second type, and the first target speed is less than the second target speed.

[0088] Specifically, in this embodiment, the fresh air fan has multiple operating wind speeds. When the operating wind speeds of the fresh air fan are different, 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 as the operating wind speed increases; conversely, both the first target speed and the second target speed show a decreasing trend as the operating wind speed decreases. Based on this, the current operating wind speed of the fresh air fan can be determined, and based on the current operating wind of the fresh air fan, the first target speed corresponding to the current first type of fresh air duct or the second target speed corresponding to the current second type of fresh air duct can be determined.

[0089] Furthermore, the speed difference between the first target speed and the second target speed shows an increasing trend as the operating wind speed of the fresh air fan increases; conversely, the speed difference between the first target speed and the second target speed shows a decreasing trend as the operating wind speed of the fresh air fan decreases. In this embodiment, the speed difference is specifically the absolute value of the difference between the first target speed and the second target speed. In other embodiments, the speed difference can be the difference between the first target speed and the second target speed. Based on this, it can be ensured that when the fresh air fan operates at the target speed corresponding to the current pipe diameter type, it can accurately reach the comfortable state of the user.

[0090] In this embodiment, taking a specific application as an example, the numerical relationships among the first target speed corresponding to the first type of fresh air duct, the second target speed corresponding to the second type of fresh air duct, and the speed difference between the first target speed and the second target speed under different operating wind speeds of the fresh air fan are as follows in the table:

[0091] Operating windshield Second target speed First target speed Speed difference Silent gear 1000 900 100 Medium wind gear 1200 1100 100 High wind gear 1600 1450 150 Powerful gear 2000 1800 200

[0092] Among them, the wind forces of the silent gear, medium wind gear, high wind gear, and strong wind gear increase in sequence.

[0093] In this embodiment, when the fresh air duct used by the air conditioner is of the large pipe diameter type, the fresh air fan adopts a relatively low operating speed. When the fresh air duct used by the air conditioner is of the small pipe diameter type, the fresh air fan adopts a relatively high operating speed, which can ensure that the operating noise of the air conditioner is relatively small while having a large fresh air volume, so as to effectively improve the comfort of indoor users when the air conditioner introduces fresh air.

[0094] Furthermore, 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 Figure 6 , step S10 includes:

[0095] Step S11, detecting the installation depth of the fresh air duct in the installation channel of the air conditioner;

[0096] Specifically, the detection data of the detection module set in the installation channel is obtained, 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, etc.

[0097] The installation depth here can be a specific value or a value range.

[0098] Step S12, determining the pipe diameter characteristic parameters of the fresh air duct according to the installation depth; wherein the fresh air ducts with different pipe diameter characteristic parameters have different installation depths in the installation channel.

[0099] Different installation depths correspond to different pipe diameter characteristic parameters. Specifically, based on the different structures of the installation parts of the fresh air ducts with different characteristic parameters or the different installation methods on the fresh air module, the calculation formulas, mapping relationships and other corresponding relationships between the installation depth and the pipe diameter characteristic parameters can be pre-set, and the pipe diameter characteristic parameters corresponding to the current installation depth can be determined based on the corresponding relationship. For example, when the installation depth is a depth value, the pipe diameter value of the fresh air duct can be calculated by 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 the pipe diameter characteristic parameter, and so on.

[0100] In this embodiment, the pipe diameter characteristic parameters include pipe diameter types, and the step of determining the pipe diameter characteristic parameters of the fresh air duct according to the installation depth includes: when the installation depth is greater than the set depth, determining the first type as the pipe diameter type; when the installation depth is less than the set depth, determining the second type as the pipe diameter type; the pipe diameter of the fresh air duct corresponding to the first type is greater than the pipe diameter of the fresh air duct corresponding to the second type.

[0101] In this embodiment, the diameter characteristic parameters of the fresh air duct are characterized by detecting the installation depth of the installation pipe, so that the air conditioner can automatically identify the diameter characteristic parameters of the fresh air duct when the fresh air duct is installed, and adjust the operating speed of the fresh air fan according to the diameter characteristic parameters without the need for user operation, so that the air conditioner can intelligently achieve lower operating noise and larger fresh air volume.

[0102] Further, in this embodiment, the installation channel has an installation opening for inserting the fresh air duct. A travel switch is provided in the installation channel. The lengths of fresh air ducts of different pipe diameter types allowed to be inserted into the installation opening are different, so as to trigger the travel switch to output different position signals. The step of obtaining the installation depth of the fresh air duct in the installation channel of the air conditioner includes: obtaining the position signal output by the travel switch; determining the installation depth according to the position signal.

[0103] The position signal is specifically the closing signal or the opening signal of the travel switch. Different position signals correspond to different installation depths.

[0104] 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, it is determined that the installation depth is less than the set depth. Based on this, when the position signal is the first position signal, it is determined that the first type of fresh air duct is currently installed in the air conditioner; when the position signal is the second position signal, it is determined that the second type of fresh air duct is currently installed in the air conditioner.

[0105] In addition, in other embodiments, when the installation depth is greater than the set depth, it is determined that the second type is the pipe diameter type; when the installation depth is less than the set depth, it is determined that the first type is the pipe diameter type. Based on this, when the position signal is the second position signal, it is determined that the first type of fresh air duct is currently installed in the air conditioner; when the position signal is the first position signal, it is determined that the second type of fresh air duct is currently installed in the air conditioner.

[0106] In this embodiment, by providing a travel switch in the installation channel of the air conditioner, automatic recognition of the pipe diameter characteristics of the fresh air duct installed in the air conditioner is realized based on the position signal output by the travel switch, improving the intelligent level of the fresh air control of the air conditioner.

[0107] 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 Figure 7 , step S10 includes:

[0108] Step S101, controlling the fresh air fan to operate at a target air volume and detecting the operating power of the fresh air fan;

[0109] In this embodiment, the target air volume can be the operating air volume of the fresh air fan set by the user, or a fixed air volume set by the air conditioner by default, or an air volume determined by the air conditioner based on the indoor environment monitoring parameters. Among them, the fresh air fan can have one air volume or more than one air volume.

[0110] The operating power of the fresh air fan here is specifically the real-time power currently output by the motor shaft of the fresh air fan. During the process of the fresh air fan maintaining the target wind speed setting, the power of the motor shaft detected in real time is used as the operating power here.

[0111] Step S102, determining the pipe diameter characteristic parameter according to the operating power; different operating powers correspond to different pipe diameter characteristic parameters.

[0112] When the fresh air fan operates at a fixed wind speed setting, if the pipe diameter characteristic parameters of the fresh air pipe installed in the air conditioner are different, the operating power of the fresh air fan is different. Specifically, the pipe diameter of the fresh air pipe corresponding to the pipe diameter characteristic parameter increases as the operating power increases; conversely, the pipe diameter of the fresh air pipe corresponding to the pipe diameter characteristic parameter decreases as the operating power decreases. Based on this, a corresponding relationship between the operating power and the pipe diameter characteristic parameter can be established in advance, and based on this corresponding relationship, the pipe diameter characteristic parameter here can be calculated or obtained by querying the mapping relationship through the operating power. Among them, the corresponding relationship here can be obtained based on the target wind speed setting, and there are different corresponding relationships between the operating power and the pipe diameter characteristic parameter under different target wind speed settings.

[0113] In this embodiment, by obtaining the pipe diameter characteristic parameter of the fresh air pipe installed in the air conditioner through the operating power when the fresh air fan operates at the target wind speed setting, the air conditioner can automatically identify the pipe diameter characteristics of the fresh air pipe without setting an additional detection module, so that the air conditioner can intelligently achieve a relatively low operating noise and a large fresh air volume without user operation.

[0114] Further, in this embodiment, the pipe diameter characteristic parameter includes the pipe diameter type, and the step of determining the pipe diameter characteristic parameter according to the operating power includes: determining the deviation amount between the operating power and the target power; the target power is the set power corresponding to the fresh air pipe of the first type; when the deviation amount is less than or equal to the set power deviation value, determining that the first type is the pipe diameter type; when the deviation amount is greater than the set power deviation value, determining 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 pipe diameter of the fresh air pipe corresponding to the second type, and the operating parameters when the fresh air fan operates at the target wind speed setting are the parameters corresponding to the first type.

[0115] In this embodiment, the deviation amount is specifically the absolute value of the difference between the operating power and the target power. In other embodiments, the deviation amount may also be the difference between the operating power and the target power.

[0116] 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.

[0117] When the fresh air fan here operates at the target wind speed, the operating parameters include the motor operating parameters and the operating power.

[0118] In this embodiment, the pipe diameter of the fresh air duct corresponding to the first type is larger than that of the fresh air duct 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 fresh air duct of the first type when the fresh air fan is at the current operating wind speed is used 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 pipe diameter type of the fresh air duct 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 of the fresh air fan and the target power is large, it can be considered that the pipe diameter type of the fresh air duct installed in the air conditioner is not the first type with a larger pipe diameter corresponding to the target power, that is, it can be determined that the pipe diameter type of the fresh air duct installed in the air conditioner is the second type different from the first type.

[0119] For example, the motor operating parameters and power are first set to the parameters in the reaming mode (i.e., installing a fresh air duct with a larger pipe diameter). Determine whether the current fresh air ventilation is turned on. If it is turned on, record the current operating power, and determine the difference between the current fresh air power and the target power. If the difference is greater than 0 and less than 0.5W, it is determined that it is 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 the non-reaming mode (i.e., installing a fresh air duct with a smaller pipe diameter), and the fresh air fan operates according to the operating parameters corresponding to the non-reaming mode.

[0120] Specifically, in this embodiment, the fresh air fan has different operating wind speeds. Before the step of determining the deviation between the operating power and the target power, it further includes: determining the target power according to the target wind speed; wherein, different target wind speeds correspond to different target powers. Specifically, the target power increases as the target wind speed increases; conversely, the target power decreases as the target wind speed decreases.

[0121] In this embodiment, a specific application is used to illustrate the target power corresponding to the fresh air ducts of different pipe diameter types under different target wind speeds, as shown in the following table:

[0122] Target wind gear Target power A (W) Target power B (W) Silent gear 6.5 (1000 rpm) 7.5 (900 rpm) Medium wind gear 8 (1200 rpm) 9 (1100 rpm) High wind gear 10.5 (1600 rpm) 12 (1450 rpm) Powerful gear 13 (2000 rpm) 15 (1800 rpm)

[0123] Among them, the silent gear, medium gear, high gear, and strong gear are wind speeds that increase in sequence.

[0124] The above target power A is the target power corresponding to the smaller pipe diameter type of the fresh air ducts of the first type and the second type (i.e., 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 pipe diameter type of the fresh air ducts of the first type and the second type (i.e., the installation mode of the fresh air duct is the reaming mode). In this embodiment, the pipe diameter of the fresh air duct corresponding to the first type is larger than that of the fresh air duct corresponding to the second type. Then, based on the target wind speed, the corresponding power B can be determined as the target power. For example, when the target wind speed is the strong wind speed, the target power is 15W, and when the target wind speed is the medium wind speed, the target power is 9W.

[0125] In this embodiment, when the types of fresh air ducts include the first type and the second type, the fresh air fan first operates with the set parameters corresponding to one of the preset pipe diameter types of the fresh air ducts. Based on the magnitude relationship between the deviation amount of the operating power of the fresh air fan detected during the operation and the target power corresponding to the preset pipe diameter type and the set power deviation value, it is characterized whether the type of the fresh air duct currently installed in the air conditioner is the same as the preset pipe diameter type. Thus, based on the magnitude relationship, the pipe diameter type of the fresh air duct currently installed in the air conditioner can be accurately determined, enabling the air conditioner to accurately control the rotation speed of the fresh air fan according to the pipe diameter type of the fresh air duct, thereby further ensuring that the air conditioner has a relatively low operating noise while having a large fresh air volume. Among them, different target wind speeds correspond to different target powers, so that no matter which wind speed the fresh air fan operates at, the pipe diameter type of the fresh air duct currently installed in the air conditioner can be accurately identified, thereby realizing precise control of the rotation speed of the fresh air fan to improve the comfort of indoor users.

[0126] 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 duct at the current operating wind speed of the fresh air fan is used as the target power here. Based on this, the deviation amount between the operating power and the target power is determined; the target powers are all preset parameters corresponding to the second type of fresh air duct; when the deviation amount is less than or equal to the set power deviation value, the second type is determined as the pipe diameter type; when the deviation amount is greater than the set power deviation value, the first type is determined as the pipe diameter type.

[0127] Based on the above two embodiments, the acquisition method of the pipe diameter characteristic parameters corresponding to the related embodiments of steps S11 to S12 is defined as the first acquisition method, and the acquisition method of the pipe diameter characteristic parameters corresponding to the related embodiments of steps S101 to S102 is defined as the second acquisition method. One of the methods can be determined from the first acquisition method and the second acquisition method based on a preset rule to acquire the pipe diameter characteristic parameters. For example, user-set parameters can be obtained, and one of the methods can be determined from the first acquisition method and the second acquisition method based on the user-set parameters; for another example, the installation status of the detection module for detecting the installation depth of the fresh air pipe in the fresh air module can be detected (specifically, it can be identified by the control device detecting whether there is a detection signal input by the detection module). If the installation status is that the detection module for detecting the installation depth of the fresh air pipe has been installed, the pipe diameter characteristic parameters are acquired according to steps S11 and S12 and their refinement schemes; if the installation status is that the detection module for detecting the installation depth of the fresh air pipe has not been installed, the pipe diameter characteristic parameters are acquired according to steps S101 and S102 and their refinement schemes.

[0128] In addition, when a travel switch is provided, when it is determined according to step S11 that the installation depth is greater than the set depth, the usage duration of the air conditioner can be obtained (specifically, it starts counting from the first activation after leaving the factory). If the usage duration is greater than the set duration, the pipe diameter characteristic parameters can be acquired according to steps S101 and S102 and their refinement schemes; if the usage duration is less than or equal to the set duration, the pipe diameter characteristic parameters can be acquired according to step S12 and its refinement schemes. Based on this, it effectively avoids the failure of the characterization of the pipe diameter characteristic parameters caused by reasons such as the long-term compression fatigue damage of the travel switch, thereby effectively improving the accuracy of the acquired pipe diameter characteristic parameters to achieve precise control of the fresh air fan and improve the comfort of indoor users.
