[0002] When the embedded air conditioner indoor unit is running, the fan drives the external airflow to be discharged through the fan outlet, and then transmitted to the surface of the heat exchanger through the channel formed by the fan shell wall and the air conditioner shell wall. Since the structural shapes of the fan shell and the air conditioner shell corresponding to different models of indoor units are also different, the air volume transmitted to the heat exchanger is uneven, thus affecting the working efficiency of the heat exchanger and the air volume of the indoor unit.

[0003] In the related art, the indoor unit includes multiple air outlets, each of which is provided with an air guide plate and a motor. The opening angle of the air guide plate is driven by the motor to adjust the opening of each air outlet. At the same time, the air outlet parameters of different air outlets are adjusted in combination with the wind speed of the indoor fan.

[0004] In the publicly available implementation process, there are at least the following problems:

[0005] In the process of adjusting the air outlet parameters of each air outlet by adjusting the wind speed of the indoor fan and the angle of the air guide plate, since multiple air outlets correspond to multiple air outlet parameters, the control logic is complicated. In addition, there is a problem that the air outlet parameters of one or more of the multiple air outlets cannot be balanced due to the wind speed being too low or too high, which affects the user experience.

[0041] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0042] In some embodiments, a control device for an indoor unit is provided, comprising a processor and a memory storing program instructions, wherein the processor is configured to execute a control method for the indoor unit when running the program instructions.

[0043] In some embodiments, in combination Figure 1 As shown, a control method for an indoor unit is provided, the indoor unit includes a shell, and a guide member, a swing blade and an air outlet arranged in the shell, the guide member can move relative to the shell, and the control method includes:

[0044] S101, the processor obtains temperature information of the indoor environment and human body information.

[0045] The temperature information of the indoor environment is detected by the temperature sensor. The human body information of the indoor environment is detected by the infrared sensor.

[0046] S102: The processor determines the swing angle of the swing blade according to the temperature information.

[0047] S103, the processor determines the operating parameters of the guide member according to the temperature information, the human body information and the swing angle of the swing blade.

[0048] S104: The processor adjusts the position of the air guide according to the operating parameters to adjust the air volume of the air outlets located on both sides of the air guide.

[0049] The control method of the indoor unit provided by the embodiment of the present disclosure obtains the temperature information and human body information of the indoor environment. According to the obtained temperature information of the indoor environment, the swing angle of the swing blade is determined. The temperature information, human body information and the swing angle of the swing blade are combined to determine the operating parameters of the air guide, and then the air guide is controlled to move to the target position to adjust the air flow on both sides of the air guide.

[0050] By combining human body information, temperature information and the swing angle of the swing blades, the human body distribution and temperature conditions of the indoor environment where the indoor unit is located can be analyzed. Combined with the swing angle of the swing blades, the relative relationship between the cooling capacity required on both sides of the guide member can be determined, and then the operation of the guide member can be controlled to adjust the air volume on both sides, so as to improve the overall comfort of the indoor environment, improve the balance of the air volume and the heat exchange effect.

[0051] Optionally, the step of acquiring temperature information and human body information of the indoor environment includes: acquiring a first indoor temperature of the first area and a second indoor temperature of the second area, and acquiring the number of first human bodies located in the first area and the number of second human bodies located in the second area.

[0052] In this embodiment, the temperature information of the first area and the second area on both sides of the guide member are obtained respectively, which are the first indoor temperature and the second indoor temperature respectively. And the number of human bodies in the first area and the second area are obtained respectively. By obtaining the temperature information on both sides, the difference between the temperatures on both sides is determined. And the air volume required on both sides is determined in combination with the human body information on both sides. Generally, the number of human bodies will have a certain impact on the ambient temperature. When the number of the first human bodies is greater than the number of the second human bodies, it means that the amount of cold required in the first area is greater than the amount of cold required in the second area. When the number of the first human bodies is less than the number of the second human bodies, it means that the amount of cold required in the second area is greater than the amount of cold required in the first area. The present disclosure obtains the first indoor temperature and the second indoor temperature on both sides of the guide member, as well as the number of the first human bodies and the number of the second human bodies, respectively, and thus can reasonably set the air volume required on both sides, thereby achieving the balance of temperature regulation on both sides, improving the accuracy of the air supply, and thus improving the user experience.

[0053] Optionally, the housing includes a first air supply unit and a second air supply unit located on both sides of the air guide, and the step of determining the swing angle of the swing blade according to the temperature information includes: obtaining a target temperature condition of the indoor environment. Determining the swing angle of the swing blade at the first air supply unit according to the first indoor temperature and the target temperature condition. Determining the swing angle of the swing blade at the second air supply unit according to the second indoor temperature and the target temperature condition.

[0054] In this embodiment, the first air supply unit and the second air supply unit are respectively provided with swing blades. The target temperature condition for the operation of the indoor unit is obtained, and the swing angles of the swing blades of the first air supply unit and the second air supply unit are determined according to the first indoor temperature and the target temperature condition, and the second indoor temperature and the target temperature condition. In this way, the corresponding swing angles of the swing blades on both sides are determined according to the relationship between the actual temperature and the target temperature condition on both sides, so as to meet the different air volume requirements on both sides, and further improve the accuracy of air volume control.

[0055] Optionally, the step of determining the swing angle of the swing blade at the first air supply unit according to the first indoor temperature and the target temperature condition includes: when the first indoor temperature meets the target temperature condition, determining that the swing angle of the swing blade at the first air supply unit maintains a current angle. When the first indoor temperature does not meet the target temperature condition, determining that the swing angle of the swing blade at the first air supply unit increases to a first preset angle.

[0056] In this embodiment, by comparing the first indoor temperature with the target temperature condition, when the first indoor temperature meets the target temperature condition, it means that the current first indoor temperature of the first area can meet the target temperature requirement set by the user, so the swing blade is controlled to maintain the current swing angle. When the first indoor temperature does not meet the target temperature requirement, it means that the current first indoor temperature of the first area does not meet the target temperature requirement set by the user, so the swing angle of the swing blade is controlled to increase to increase the air supply volume of the first area, thereby achieving the effect of rapid temperature adjustment.

[0057] Optionally, the step of determining the swing angle of the swing blade at the second air supply unit according to the second indoor temperature and the target temperature condition includes: when the second indoor temperature meets the target temperature condition, determining that the swing angle of the swing blade at the second air supply unit maintains a current angle. When the second indoor temperature does not meet the target temperature condition, determining that the swing angle of the swing blade at the second air supply unit increases to a second preset angle.

[0058] In this embodiment, by comparing the second indoor temperature with the target temperature condition, when the second indoor temperature meets the target temperature condition, it means that the second indoor temperature of the second area can meet the target temperature requirement set by the user, so the swing blade is controlled to maintain the current swing angle. When the second indoor temperature does not meet the target temperature requirement, it means that the second indoor temperature of the second area does not meet the target temperature requirement set by the user, so the swing angle of the swing blade is controlled to increase to increase the air supply volume of the second area, thereby achieving the effect of rapid temperature adjustment.

[0059] In some embodiments, in combination Figure 2 As shown, a control method for an indoor unit is provided, the indoor unit includes a shell, and a guide member, a swing blade and an air outlet arranged in the shell, the guide member can move relative to the shell, and the control method includes:

[0060] S201, the processor obtains temperature information of the indoor environment and human body information.

[0061] The temperature information of the indoor environment is detected by the temperature sensor. The human body information of the indoor environment is detected by the infrared sensor.

[0062] S202: The processor determines the swing angle of the swing blade according to the temperature information.

[0063] S203: The processor obtains the operation mode and target setting temperature of the indoor unit.

[0064] S204: The processor determines a swing blade factor according to the swing angle of the swing blade.

[0065] S205: The processor determines a preset formula corresponding to the operating mode according to the operating mode.

[0066] S206, the processor determines the operating parameters of the guide member through a preset formula according to the temperature information, human body information, the swing factor and the target set temperature.

[0067] S207: The processor adjusts the position of the air guide according to the operating parameters to adjust the air volume of the air outlets located on both sides of the air guide.

[0068] The control method of the indoor unit provided by the present disclosure combines the temperature information on both sides of the air guide, human body information, the swing leaf factor, and the target setting temperature, and determines the operating parameters of the air guide through a preset formula, thereby improving the accuracy of determining the target position of the air guide, so as to improve the accuracy of cold delivery in the first area and the second area on both sides of the air guide, thereby meeting the user's use needs and improving the user's use experience. Compared with the adjustment method in the related art, the balance of indoor cold capacity is improved.

[0069] Optionally, according to the operation mode, the step of determining a preset formula corresponding to the operation mode includes:

[0070] When the operation mode is heating mode, the preset formula is:

[0071]

[0072] When the operating mode is cooling mode, the preset formula is:

[0073]

[0074] Wherein, ΔL is the operating parameter of the guide member, α is the swing factor, T1 is the first indoor temperature, T2 is the second indoor temperature, T0 is the target setting temperature, N1 is the first number of people, N2 is the second number of people, and L is the width of the air outlet.

[0075] In this embodiment, corresponding preset formulas are set for different operation modes to improve the accuracy of air supply and the air supply effect in different operation modes. In addition, by calculating the proportion of the temperature difference on both sides and the proportion of the difference in the number of people, the parameter information of the dominant factor is determined, and then the moving direction of the guide is determined, thereby improving the accuracy of temperature control and the user experience.

[0076] Specifically, in heating mode: for the influence of temperature factors: the air volume on the side with lower temperature should be increased, and the guide should be moved to the opposite side to make up for the difference in temperature on the side with lower temperature to reach the target set temperature as much as possible. For the influence of the number of people: the side with more people should reach the set temperature first to meet the needs of the majority of people; at the same time, the opening angle of the swing blade also plays a direct role in the influence of the air volume, so it is necessary to combine the swing blade factors on both sides to determine the target position of the guide.

[0077] In cooling mode, for the influence of temperature factors: the air volume on the side with higher temperature should be increased, and the guide should be moved to the opposite side to make up for the difference in temperature between the side with higher temperature and the set temperature as much as possible. For the influence of the number of people: the side with more people should reach the set temperature first to meet the needs of the majority of people; at the same time, the opening angle of the swing blade also has a direct effect on the air volume, so it is necessary to combine the swing blade factors on both sides to determine the target position of the guide.

[0078] Optionally, the step of determining the operating parameters of the guide member by a preset formula includes: calculating ΔL by a preset formula. When ΔL is a negative value, the direction of movement of the guide member is determined to be moving toward the first area, and the moving distance is the absolute value of ΔL. When ΔL is a positive value, the direction of movement of the guide member is determined to be moving toward the second area, and the moving distance is ΔL.

[0079] In this embodiment, the operating parameters of the guide member include the moving direction and the moving distance, and ΔL is calculated by the above preset formula. The positive or negative value of ΔL indicates the moving direction of the guide member, and the absolute value of ΔL indicates the moving distance of the guide member. Further, when ΔL is a negative value, the moving direction of the guide member is determined to be moving toward the first area, and when ΔL is a positive value, the moving direction of the guide member is determined to be moving toward the second area. In this way, the moving parameters of the guide member can be determined by the preset formula, and then the air volume of the first area and the second area can be adjusted by controlling the guide member to run to the target position.

[0080] Example 1: The current operation mode of the indoor unit is cooling mode, and the preset formula is:

[0081] Among them, L is the width of the air outlet, which is a positive number and has no effect on the moving direction. It can be set specifically according to the size of the actual structure. No specific numerical distance is given here. Therefore, no specific value is given in the example.

[0082] Example 1.1: T0 is 26°C, T1 is 29°C, T2 is 28°C, N1 is 30 people, N2 is 25 people, α is 1, and according to the preset formula, ΔL=(1×(29-28) / 26+(30-25) / (30+25))×L=0.13L, that is, the guide member is controlled to move to the second area, and the moving distance is 0.13L.

[0083] Example 2.1: T0 is 26°C, T1 is 29°C, T2 is 28°C, N1 is 25 people, N2 is 30 people, α is 1, and according to the preset formula, ΔL=(1×(29-28) / 26+(25-30) / (30+25))×L=-0.053L, that is, the guide is controlled to move to the first area, and the moving distance is 0.053L.

[0084] Example 2: The current operation mode of the indoor unit is heating mode, and the preset formula is:

[0085] Among them, L is the width of the air outlet, which is a positive number and has no effect on the moving direction. It can be set specifically according to the size of the actual structure. No specific numerical distance is given here. Therefore, no specific value is given in the example.

[0086] Example 2.1: T0 is 27°C, T1 is 24°C, T2 is 25°C, N1 is 27 people, N2 is 30 people, α is 1, and according to the preset formula, ΔL=(1×(-(24-25) / 27)+(27-30) / (27+30))×L=-0.015L, that is, the guide is controlled to move to the first area, and the moving distance is 0.015L.

[0087] Example 2.2: T0 is 27°C, T1 is 24°C, T2 is 26°C, N1 is 27 people, N2 is 28 people, α is 1, and according to the preset formula, ΔL=(1×(-(24-26) / 27)+(27-28) / (27+28))×L=0.056L, that is, the guide member is controlled to move to the second area, and the moving distance is 0.056L.

[0088] Optionally, the step of determining the swing blade factor according to the swing angle of the swing blade includes: obtaining the swing angle of the first swing blade at the first air supply part and the swing angle of the second swing blade at the second air supply part. Determine the first factor β according to the swing angle of the first swing blade. Determine the second factor γ according to the swing angle of the second swing blade. Determine the swing blade factor α according to the first factor β and the second factor γ.

[0089] In this embodiment, considering that the swing angles of the first swing blade and the second swing blade are not necessarily the same, the swing blade factor is determined by the first factor β and the second factor γ corresponding to the first swing blade and the second swing blade to improve the accuracy of the air volume output on both sides.

[0090] Optionally, according to the swing angle of the first swing blade, the step of determining the first factor β includes: comparing the swing angle with a preset angle factor mapping relationship table to determine the first factor β corresponding to the swing angle.

[0091] Optionally, the step of determining the second factor γ according to the swing angle of the second swing blade includes: comparing the swing angle with a preset angle factor mapping relationship table to determine the second factor γ corresponding to the swing angle.

[0092] Optionally, the angle factor mapping relationship table is shown in Table 1, where the angle of each gear can be set according to actual conditions. For example, the first gear angle is 30°, the second gear angle is 40°, the third gear angle is 50°, the fourth gear angle is 60°, the fifth gear angle is 70°, and the sixth gear angle is 80°.

[0093] Table 1

[0094]

[0095]

[0096] Optionally, the step of determining the swing factor α according to the first factor β and the second factor γ includes: α=β×γ.

[0097] Exemplarily, the swing angle of the first swing blade is the second gear angle, then according to Table 1, the first factor β is 1.2; the swing angle of the second swing blade is the third gear angle, then according to Table 1, the second factor γ is determined to be 1.15, then α=1.2×1.15=1.38.

[0098] Optionally, the step of determining the swing angle of the swing blade according to the temperature information includes: determining the absolute value ΔT of the difference between the temperature information and the target setting temperature. According to the preset difference range in which the difference ΔT is located, the corresponding swing angle of the swing blade is determined. In this way, the swing angle of the swing blade is determined according to the difference ΔT between the actual indoor temperature and the target setting temperature, and the cooling capacity matching the difference ΔT is output to improve the indoor temperature regulation effect.

[0099] Optionally, the corresponding relationship between the preset difference range and the swing angle is shown in Table 2, wherein T1<T2<T3<T4<T5.

[0100] Table 2

[0101] Preset difference range Swing angle <![CDATA[T5<ΔT]]> Six angles <![CDATA[T4<ΔT≤T5]]> Five angles <![CDATA[T3<ΔT≤T4]]> Four angles <![CDATA[T2<ΔT≤T3]]> Three angles <![CDATA[T1<ΔT≤T2]]> Second gear angle <![CDATA[0℃≤ΔT≤T1]]> First gear angle

[0102] Among them, the values ​​of T1, T2, T3, T4, and T5 can be specifically set according to actual usage.

[0103] Among them, in the cooling mode, when the target setting temperature is ≥ the second indoor temperature, and the target setting temperature is ≥ the first indoor temperature, the first swing blade and the second swing blade are in a closed state.

[0104] In the heating mode, when the target setting temperature is ≤ the second indoor temperature and the target setting temperature is ≤ the first indoor temperature, the first swing blade and the second swing blade are in a closed state.

[0105] Optionally, the value ranges of T1, T2, T3, T4, and T5 may be: 1.5°C≤T1≤3°C, 3°C≤T2≤4.5°C, 4°C≤T3≤5.5°C, 5°C≤T4≤6.5°C, and 6°C≤T5≤7.5°C, respectively.

[0106] Exemplarily, the corresponding relationship between the preset difference range and the swing angle is as follows:

[0107] When 0℃≤ΔT≤2℃, the swing angle corresponds to the first gear angle;

[0108] When 2℃<ΔT≤3℃, the swing angle corresponds to the second gear angle;

[0109] When 3℃<ΔT≤4℃, the swing angle corresponds to the third gear angle;

[0110] When 4℃<ΔT≤5℃, the swing angle corresponds to the fourth gear angle;

[0111] When 5℃<ΔT≤6℃, the swing angle corresponds to five levels;

[0112] When ΔT>6°C, the swing angle corresponds to the sixth gear angle.

[0113] Example 1: In cooling mode, the target set temperature is 26°C, the first indoor temperature of the first zone is 26°C; and the second indoor temperature of the second zone is 27°C.

[0114] The difference between the first indoor temperature and the target setting temperature is: 0, and the swing angle of the first swing blade corresponds to the first angle; the difference between the second indoor temperature and the target setting temperature is: 1°C, and the swing angle of the second swing blade corresponds to the first angle.

[0115] Example 2: In heating mode, the target set temperature is 26°C, the first indoor temperature of the first zone is 23°C; and the second indoor temperature of the second zone is 24°C.

[0116] The absolute value of the difference between the first indoor temperature and the target setting temperature is 3°C, and the swing angle of the first pendulum corresponds to the second gear angle; the absolute value of the difference between the second indoor temperature and the target setting temperature is 4°C, and the swing angle of the second pendulum corresponds to the third gear angle.

[0117] In order to improve the indoor heat exchange effect, the number of people in the first area and the second area is detected by the infrared sensor at preset intervals. In this way, the air volume can be adjusted in time according to the changes in the number of people, so as to improve the user experience.

[0118] Optionally, the preset period ranges from half an hour to three hours. It can be set specifically according to the actual usage scenario. For example, a classroom can be reasonably set according to the class hours. A residence can be set according to the family life rules. I will not list them one by one here.

[0119] In some embodiments, in combination Figures 1 to 7 As shown, an air-conditioning indoor unit 100 is provided, and the air-conditioning indoor unit 100 is applicable to the control method of the indoor unit described in any of the above embodiments. The air-conditioning indoor unit 100 includes: a housing 110, a fan assembly 120 and a guide assembly 140. The housing 110 includes a cavity 111.
