[0041] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0042] At present, air conditioners have been popular in most areas of China and have gradually become a necessity for people's home. Especially in the south where unified heating is not implemented, people mainly rely on air conditioning heating to keep warm in winter. However, due to the poor heat resistance of the air outlet grille located at the air outlet of the air conditioner, the air outlet grille in the high-temperature hot air environment for a long time is prone to heat stress concentration, distortion and even local fracture. At the same time, the air outlet grille belongs to the appearance part of the air conditioner, which affects the appearance and the initial air supply angle, and brings a bad experience to the user. Based on the above status quo, the embodiments of the present disclosure provide a control method and device for air conditioner, air conditioner and storage medium, which can adjust the air outlet grille that appears thermal deformation in real time and ensure the air supply effect of the air conditioner.

[0043] Figure 1 is a schematic diagram of a use scenario of an air conditioner provided by the embodiments of the present disclosure.

[0044] In combination with Figure 1 As shown in the figure, the use scenario includes an air conditioner 100 and a server 110 for communication with the air conditioner 100.

[0045] The air conditioner 100 can access the home WiFi network and communicate with the control terminal such as a mobile phone and a cloud server. The user can also control the air conditioner 100 to execute the instruction program through the smart phone application.

[0046] The server 110 can communicate with or remotely control the air conditioner 100; the air conditioner 100 can upload the parameters of its own operation to the server 110 after obtaining the parameters.

[0047] In other implementation scenarios of the present solution, a terminal device can also be included for communication with the air conditioner 100 and / or the server 110. Here, the terminal device refers to a smart device in the smart home application scenario, such as a smart phone, a wearable device, a smart mobile device, a virtual display device, etc.

[0048] Figure 2 is a schematic diagram of an air conditioner structure provided by the embodiments of the present disclosure.

[0049] In combination with Figure 2As shown, the air conditioner includes an air outlet grille 103 and a driving device 104. The air outlet grille 103 is arranged at the air outlet 102 of the air conditioner, and the driving device 104 is connected to the air outlet grille 103 and is configured to controllably displace the air outlet grille in a set direction to compensate for the thermal deformation amount of the air outlet grille.

[0050] Since the air outlet grille 103 is located at the air outlet 102 of the air conditioner and has poor heat resistance, in the case that the air outlet 102 of the air conditioner delivers high-temperature hot air for a long time, the air outlet grille 103 is prone to thermal deformation. After deformation, the air supply angle of the air outlet grille 103 deviates, affecting the air supply effect. The embodiment of the present disclosure sets the driving device 104 to displace the air outlet grille 103 in a set direction, thereby compensating for the thermal deformation amount and reducing the influence of the air supply angle deviation on the air supply effect.

[0051] Optionally, the above-mentioned air conditioner includes a framework 105, which is constructed inside the shell 101 of the air conditioner and is connected to the bottom of the air outlet grille 103. The driving device 104 is arranged at the connection between the framework 105 and the air outlet grille 103.

[0052] By controlling the driving device 104 to adjust the air outlet grille 103 in real time, timely discovery and adjustment can be ensured when the air outlet grille 103 deforms, thereby ensuring the air supply effect and guaranteeing the safety and aesthetics of the air conditioner.

[0053] Further, the driving device 104 can be a stepper motor. The stepper motor can be arranged on an intermediate piece at the connection between the framework 105 and the air outlet grille 103. The intermediate piece can be freely moved in a set direction, so that the stepper motor can drive the intermediate piece to move and in turn drive the air outlet grille to displace in a set direction to compensate for the thermal deformation amount.

[0054] In other embodiments, the driving device 104 can also be a servo motor or the like, which can execute program instructions to drive the air outlet grille to displace in a set direction to compensate for the thermal deformation amount.

[0055] Figure 3 The present disclosure provides a control method for an air conditioner, which is applied to the air conditioner shown in Figure 1 or 2. The control method for an air conditioner includes:

[0056] In step S301, the processor detects the first temperature of the air outlet grille and the second temperature after a set time, and obtains the temperature difference between the second temperature and the first temperature.

[0057] The setting time period can be 30 seconds, 1 minute, or other time periods. The temperature difference before and after the setting time period can be used to obtain the temperature change of the air outlet grille in the time period, and thus the running mode of the air conditioner, the heating degree of the air outlet grille, and other information can be determined.

[0058] Here, the first temperature of the air outlet grille is T0, and the second temperature is T1.

[0059] If the temperature difference T1-T0 between the second temperature and the first temperature is less than 0, it indicates that the air outlet temperature of the air conditioner decreases after the setting time period, and the air conditioner can be in a running mode for achieving cooling. At this time, the temperature sensor arranged in the air conditioner continuously monitors the temperature of the air outlet grille until the condition T1-T0>0 is detected, and the processor drives the air conditioner to perform the next action according to the instruction.

[0060] If the temperature difference T1-T0 between the second temperature and the first temperature is greater than 0, it indicates that the air outlet temperature of the air conditioner increases after the setting time period, and the air conditioner can be in a running mode for achieving heating. At this time, step S302 is entered.

[0061] In step S302, the processor determines the thermal deformation amount of the air outlet grille according to the temperature difference.

[0062] The thermal deformation amount is a concrete representation of the deformation degree of the air outlet grille after being heated. The greater the temperature difference, the more obvious the deformation of the air outlet grille after being heated, and the greater the thermal deformation amount.

[0063] In step S303, the processor controls the driving device to make the air outlet grille displace along a set direction to compensate for the thermal deformation amount of the air outlet grille according to the thermal deformation amount of the air outlet grille.

[0064] The thermal deformation of the air outlet grille changes the original gap between the air outlet grille and the skeleton. The driving device is controlled to make the air outlet grille displace along a set direction to compensate for the thermal deformation gap, reduce the influence of the changed gap between the air outlet grille and the skeleton, and thus ensure the air supply effect.

[0065] In this way, the temperature of the air outlet grille of the air conditioner is detected, the temperature difference is obtained to determine the thermal deformation amount of the air outlet grille, and then the driving device is driven to displace the air outlet grille to compensate for the thermal deformation amount according to the thermal deformation amount. Due to the real-time nature of temperature detection, the deformation of the air outlet grille of the air conditioner can be found in time and adjusted to ensure the air supply effect and the safety of the air conditioner equipment.

[0066] The following describes how to determine the thermal deformation amount of the air outlet grille in combination with specific embodiments.

[0067] Figure 4 The control method for the air conditioner provided by the embodiment of the present disclosure is applied to Figure 1Or 2. The control method for the air conditioner comprises:

[0068] In step S401, the processor detects a first temperature of the air outlet grille and a second temperature after a set time, and obtains a temperature difference between the second temperature and the first temperature.

[0069] In step S402, the processor obtains a critical temperature rise variation of the air outlet grille thermal deformation.

[0070] The critical temperature rise variation refers to a calibration temperature rise variation when the air outlet grille is deformed by heat.

[0071] Due to the differences in the manufacturing materials, shapes, sizes, etc. of the air outlet grilles of air conditioners, the critical temperature rise variations of the air outlet grilles are also different. Therefore, the corresponding critical temperature rise variations need to be set for different air conditioners.

[0072] Further, the method for obtaining the critical temperature rise variation is as follows:

[0073] In the heat-sensitive area of the air outlet grille of the air conditioner, temperature points are arranged. When the air outlet grille is deformed under the condition that the indoor heating mode is turned on, the temperature value of the air outlet grille at this moment is recorded, and the temperature difference between the temperature value at this moment and the temperature of the air outlet grille before the set time is obtained. Correspondingly, the temperature difference is recorded as the critical temperature rise variation ΔT of the air outlet grille of the air conditioner. td .

[0074] In step S403, the processor determines whether the temperature difference is greater than the critical temperature rise variation.

[0075] If the temperature difference is greater than the critical temperature rise variation, it indicates that the air outlet grille of the air conditioner is deformed by heat, and then step S404 is entered to execute the next instruction operation; otherwise, step S401 is returned to continue detecting the temperature of the air outlet grille.

[0076] In step S404, the processor determines the thermal deformation amount positively correlated with the temperature difference.

[0077] Since the greater the temperature difference is, the more obvious the deformation of the air outlet grille after being heated is, the corresponding thermal deformation amount is also greater.

[0078] Optionally, the processor determines the thermal deformation amount positively correlated with the temperature difference, including:

[0079] The processor obtains the corresponding relationship between the temperature rise interval segment and the air outlet grille thermal deformation amount.

[0080] The processor determines the corresponding air outlet grille thermal deformation amount according to the temperature rise interval segment where the temperature difference is located.

[0081] Further, the correspondence between the temperature rise interval section and the heat deformation amount of the air outlet grille can be in the form of a one-to-one correspondence data table. In this case, the correspondence between the temperature rise interval section and the heat deformation amount of the air outlet grille can be stored in a database in advance. After obtaining the temperature difference value of the preset time period, the heat deformation amount of the air outlet grille corresponding to the temperature difference value can be obtained by querying the database.

[0082] Further, the method for obtaining the one-to-one correspondence data table of the temperature rise interval section and the heat deformation amount of the air outlet grille is as follows:

[0083] For the air outlet grille model, the finite element method is used to analyze the thermal characteristics by substituting the common temperature rise amount after starting the air conditioner heating mode in winter. The heat deformation amount of the air outlet grille corresponding to different temperature rise interval sections can be obtained.

[0084] For example, Table 1 shows the correspondence between the temperature rise interval section and the heat deformation amount ΔL Y of the air outlet grille.

[0085] Table 1

[0086] ΔT (°C) Delta L Y ]] Delta T td Delta T X1 A < ΔT < B X2 B < ΔT < C X3

[0087] According to the numerical interval of the temperature rise interval section ΔT, the heat deformation amount ΔL Y of the air outlet grille is determined; the larger the value of ΔT, the larger the value of ΔL Y ; X3>X2>X1.

[0088] Alternatively, the correspondence between the temperature rise interval section and the heat deformation amount of the air outlet grille can be in the form of a formula. After obtaining the temperature difference value of the preset time period, the temperature difference value is used as the argument of the formula to calculate the heat deformation amount of the air outlet grille corresponding to the temperature difference value.

[0089] Further, according to the temperature difference value, the heat deformation amount positively correlated with the temperature difference value is calculated, including:

[0090] ΔL Y =A*ΔT, to obtain the heat deformation amount ΔL Y of the air outlet grille; wherein A is a calculation factor related to the air outlet grille, and ΔT is the temperature difference value; A>0.

[0091] Further, the calculation factor A=α*L Y0 , wherein α is the thermal expansion coefficient corresponding to the material of the air outlet grille, and L Y0 is the initial size of the air outlet grille.

[0092] Further, the heat deformation amount ΔL Y of the air outlet grille is positively correlated with the temperature difference ΔT. The larger the temperature difference, the larger the heat deformation amount of the air outlet grille.

[0093] In some cases, different temperature differences for the same air conditioner can result in different thermal deformation amounts.

[0094] For example, the temperature difference after the set time length is acquired by the air conditioner for the first time is ΔT1 (ΔT1> ΔT td ); the temperature difference after the set time length is acquired for the second time is ΔT2 (ΔT2> ΔT td , ΔT1> ΔT2). As can be known from the above description, the greater the temperature difference, the greater the thermal deformation amount of the air outlet grille, and the thermal deformation amount corresponding to ΔT1 is greater than the thermal deformation amount corresponding to ΔT2.

[0095] For another example, the first temperature of the air outlet grille acquired for the first time by the air conditioner is -10℃, and the second temperature after the set time length is acquired is 15℃; the first temperature acquired for the second time is 10℃, and the second temperature is 35℃, and the temperature difference acquired twice is 25℃, assuming that 25℃> ΔT td , according to the formula, the thermal deformation amount ΔL Y1 of the air outlet grille corresponding to the temperature difference acquired twice is A*25℃, ΔL Y2 = A*25℃, ΔL Y1 = ΔL Y2 . As can be known from the above description, the thermal deformation amount generated by the same temperature rise interval segment is not affected by the start and end temperatures of the interval segment.

[0096] Step S405, the processor controls the driving device to make the air outlet grille displace along the set direction according to the thermal deformation amount, so as to compensate for the thermal deformation amount of the air outlet grille.

[0097] In this way, by detecting the temperature of the air outlet grille of the air conditioner, the temperature difference is acquired to determine the thermal deformation amount positively correlated with the temperature difference, and then the corresponding relationship between the temperature rise interval segment and the thermal deformation amount of the air outlet grille is acquired to determine the thermal deformation amount corresponding to the temperature difference, so as to control the driving device to make the air outlet grille displace along the set direction according to the thermal deformation amount, to compensate for the thermal deformation gap in real time and ensure the air supply effect.

[0098] The following describes how to control the driving device to make the air outlet grille displace along the set direction in combination with an embodiment.

[0099] Figure 5 The control method for the air conditioner provided in the embodiment of the present disclosure is applied to the air conditioner shown in FIG. 1 or 2. The control method for the air conditioner comprises the following steps. Figure 1

[0100] Step S501, the processor detects the first temperature of the air outlet grille and the second temperature after the set time length, and obtains the temperature difference between the second temperature and the first temperature.

[0101] ​In step S502, the processor acquires a critical temperature rise variation of the heat deformation of the air outlet grille.

[0102] In step S503, the processor determines whether the temperature difference is greater than the critical temperature rise variation.

[0103] If the temperature difference is greater than the critical temperature rise variation, the process proceeds to step S504; otherwise, the process proceeds to step S501 to continue detecting the temperature of the air outlet grille.

[0104] In step S504, the processor determines a heat deformation amount positively correlated with the temperature difference.

[0105] In step S505, the processor determines the operation parameter of the driving device according to the heat deformation amount.

[0106] Optionally, the processor determines the operation parameter of the driving device according to the heat deformation amount, including:

[0107] The processor determines a displacement distance of the air outlet grille for compensating the heat deformation amount according to the heat deformation amount of the air outlet grille.

[0108] The processor determines the operation parameter of the driving device according to the displacement distance.

[0109] Further, the processor determines the displacement distance of the air outlet grille for compensating the heat deformation amount according to the heat deformation amount of the air outlet grille, including:

[0110] The processor acquires a corresponding relationship between the heat deformation amount and the displacement distance of the air outlet grille for compensating the heat deformation amount, and determines the displacement distance according to the heat deformation amount.

[0111] Specifically, the corresponding relationship between the heat deformation amount and the displacement distance is a 1:1 proportional relationship, that is, after a certain amount of heat deformation is generated, the driving device is controlled to adjust the air outlet grille to generate a displacement distance of the same amount. After the heat deformation amount of the air outlet grille is obtained, the displacement distance corresponding to the heat deformation amount can be obtained.

[0112] Further, the processor determines the operation parameter of the driving device according to the displacement distance, including:

[0113] The processor acquires a corresponding relationship between the displacement distance and the operation parameter of the driving device, and determines the operation parameter of the driving device according to the displacement distance.

[0114] Specifically, the corresponding relationship between the displacement distance and the operation parameter of the driving device can be in the form of a one-to-one correspondence data table. In this case, the corresponding relationship between the displacement distance and the operation parameter can be stored in a database in advance. After the displacement distance of the air outlet grille for compensating the heat deformation amount is obtained, the corresponding operation parameter can be obtained by querying the database.

[0115] Further, in the case that the driving device is a stepper motor, the operation parameter can be the distance moved by the stepper motor. By adding a stepper motor at the position where the air outlet grille is connected below the skeleton, when the program detects that the air outlet grille is deformed by heat, the processor converts the displacement distance of the air outlet grille used for compensating the heat deformation amount into the displacement distance of the stepper motor, and then issues a command to drive the stepper motor to output a corresponding amount of linear displacement, so that the air outlet grille has a corresponding displacement amount in the set direction to offset the compensation heat deformation amount.

[0116] Further, in the case that the driving device includes a stepper motor and a lead screw, the operation parameter can also be the movement stroke value of the lead screw. Here, the lead screw is arranged in the vertical direction, one end of which is connected to the output end of the stepper motor, and the other end is connected to the bottom of the air outlet grille. Through the operation of the stepper motor, the lead screw can be displaced in the vertical direction and drive the air outlet grille to be synchronously displaced. When it is detected that the air outlet grille is deformed by heat, the processor converts the displacement distance of the air outlet grille used for compensating the heat deformation amount into the movement stroke value of the lead screw, and then issues a command to drive the stepper motor to rotate, so that the lead screw moves in the vertical direction according to the movement stroke value, and in turn drives the air outlet grille to have a corresponding displacement amount to offset the compensation heat deformation amount.

[0117] Further, in the embodiment, the displacement direction of the air outlet grille is set to the vertical direction. Since the size of the air outlet grille is the largest in the vertical direction, the contribution to the heat deformation is also the largest, so the displacement direction of the air outlet grille used for compensating the heat deformation amount is set to the vertical direction.

[0118] Step S506, the processor controls the driving device to operate according to the corresponding operation parameter according to the operation parameter, so as to compensate the heat deformation amount of the air outlet grille.

[0119] In this way, by detecting the temperature of the air outlet grille of the air conditioner, obtaining the temperature difference value to determine the heat deformation amount positively correlated with the temperature difference value, determining the operation parameter of the driving device according to the heat deformation amount, and then controlling the driving device according to the operation parameter to make the air outlet grille displace in the set direction, the heat deformation gap is compensated in real time to ensure the accuracy of the air supply effect and the adjustment result.
