[0003] Currently, for a variable-frequency air conditioner, the frequency will be automatically reduced to reduce the output of the air conditioner's capacity to meet the user's set requirements. At the same time, the automatic change of the indoor fan speed and the outdoor fan speed is superimposed to reduce the output of the air conditioner's capacity to meet the user's capacity requirements under low load; for the different densities of the air blown in the cooling and heating modes, the control method adopted is to use a large air deflector to improve the air supply effect in the room. Summary of the Invention

[0004] The present disclosure provides a control method and device for an air conditioning device, an electronic device, a chip, and a medium to solve the problem that the air conditioning device cannot continuously reduce the frequency after meeting the user's requirements, resulting in an excessive indoor load of the air conditioner.

[0005] In a first aspect embodiment of the present disclosure, a control method for an air conditioning device is proposed.

[0006] In some embodiments of the present disclosure, the method further includes: determining whether the environmental parameters of the air conditioning device reach the target state. Wherein, determining whether the environmental parameters of the air conditioning device reach the target state includes: real-time detecting the indoor temperature of the air conditioning device in the current mode; when the first difference between the indoor temperature and the target temperature in the current mode meets a preset condition, determining that the environmental parameters of the air conditioning device reach the target state.

[0007] In some embodiments of the present disclosure, when the current mode is the cooling mode, the preset condition is that the first difference within the first time period is less than or equal to the first value; when the current mode is the heating mode, the preset condition is that the first difference within the second time period is less than or equal to the second value, where the first value is an integer and the second value is a negative number.

[0010] In the above embodiments, when the environmental parameters of the air conditioning device reach the target state, by combining the wind speed setting with the air deflector of the air conditioning device, the air outlet effect of the air conditioning device under different wind speed settings is improved, thereby improving indoor comfort; at the same time, the inner tube temperature can be corrected to better achieve the target temperature of the indoor environment set by the user and improve the user's comfort.

[0014] In some embodiments of the present disclosure, the method further includes: when the second difference meets the target range, maintaining the air deflector angle at the third angle or the fourth angle or the fifth angle.

[0015] In the above embodiments, the air deflector angle of the air conditioner device is gradually adjusted according to the change rate of the inner pipe temperature to control the indoor load output of the air conditioner, expand the adjustment ability of the air conditioner under low load, and further improve the comfort of indoor users.

[0038] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure.

[0039] For variable-frequency air conditioners, the current control method is to control the indoor load input by reducing parameters such as the operating frequency of the compressor and the rotational speed of the indoor unit. However, variable-frequency motors are prone to reliability problems such as unstable operation at extremely low frequencies. Since the minimum operating frequency of the motor cannot be infinitely reduced, and the efficiency of the motor is also poor at extremely low operating frequencies, it results in an excessive indoor load of the air conditioner, affecting the user's comfort.

[0040] Regarding the different densities of cold air and hot air blown out in the cooling and heating modes of the air conditioner, there are differences in the indoor air outlet range and indoor temperature change at the same air deflector angle. Although using a large air deflector can improve the indoor air supply effect and send the air outlet to the corresponding position better, there is no corresponding control strategy for improving the temperature uniformity in different wind speed and angle conditions.

[0041] Therefore, the present disclosure proposes a control method for an air conditioning device. When the environmental parameters of the air conditioning device reach the target state, by detecting the inner pipe temperature or the wind speed, the air deflector angle is adjusted according to different inner pipe temperatures or wind speeds, so that the recovered air volume of the air conditioning device reaches the target value, thereby improving the air supply effect and the user's comfort experience on the premise of meeting the user's needs.

[0042] The control method of the present disclosure can combine the large air deflector with the air conditioning equipment.

[0043] In some embodiments, the control method of the present disclosure can be applied to an air conditioning equipment with an upper air outlet and a lower air return structure. The air outlet is arranged at the upper part of the side surface of the air conditioning equipment or the upper surface of the air conditioning equipment, and the air return port is arranged at the lower surface of the air conditioning equipment. By way of example, as Figure 1 shown in (1) below, the air deflector of the air conditioning equipment forms a certain angle with the panel body of the air conditioning equipment, so that the air outlet direction of the air outlet of the air conditioning equipment is consistent with the angle. A air return port is arranged below the air conditioning equipment. When the air outlet angle meets certain conditions, the air outlet of the air conditioner will be recycled to the indoor unit of the air conditioning equipment through the air return port, thus forming an air volume cycle of upper air outlet and lower air return.

[0044] In some embodiments, the control method of the present disclosure can be applied to an air conditioning equipment with a lower air outlet and an upper air return structure. The air outlet is arranged at the lower part of the side surface of the air conditioning equipment or the lower surface of the air conditioning equipment, and the air return port is arranged at the upper part of the side surface of the air conditioning equipment or the upper surface of the air conditioning equipment. By way of example, as Figure 1 shown in (2) below, the air deflector of the air conditioning equipment is arranged on the lower surface of the air conditioning equipment. By adjusting the downward inclination angle of the air deflector, the air outlet direction is controlled to reach the target angle, and part of the air volume is recycled through the air return port arranged at the upper part of the side surface, forming an air volume cycle of lower air outlet and upper air return.

[0045] In the above embodiments, for the air conditioning equipment with a lower air outlet and an upper air return structure, the width of the air deflector of the air conditioning equipment is greater than one-third of the height of the panel of the air conditioning equipment. Wherein, the width of the air deflector is the width perpendicular to the panel. Specifically, since it is the air deflector of the lower air outlet, the air deflector is located on the lower surface of the air conditioning equipment or the lower part of the side surface of the air conditioning equipment. Therefore, in order to enable the air outlet to be recycled through the air return port arranged above, the width of the air deflector needs to be greater than one-third of the panel height to achieve the effect of sending the air outlet upward, so that the air return port can recycle the air volume and achieve the purpose of air volume cycle.

[0046] Next, the control method and control device of the air conditioning equipment proposed in the present application will be introduced in detail with reference to the accompanying drawings.

[0047] Figure 2 The method flow chart of a control method of an air conditioning equipment proposed in an embodiment of the present disclosure is as Figure 2 shown. The method includes the following steps:

[0048] Step 201, in response to the environmental parameters of the air conditioning equipment reaching the target state, determine the current internal pipe temperature and / or the current wind speed of the air conditioning equipment.

[0049] In some embodiments, the environmental parameters of the air conditioning equipment can be the indoor temperature, indoor humidity, etc. of the air conditioning equipment.

[0050] In some embodiments, the control method further includes: determining whether the environmental parameters of the air conditioning equipment reach the target state.

[0051] In some embodiments, determining whether the environmental parameters of the air conditioning equipment reach the target state includes: detecting the indoor temperature of the air conditioning equipment in the current mode in real time; determining that the environmental parameters of the air conditioning equipment reach the target state when the first difference between the indoor temperature and the target temperature in the current mode meets a preset condition.

[0052] In some embodiments, the target state may be a temperature-reached state, and the temperature-reached state may have different judgment criteria in different current modes. Among them, the current mode may be a cooling mode or a heating mode.

[0053] In some embodiments, the indoor temperature in the current mode may be measured by a temperature sensor arranged outside the air conditioning equipment.

[0054] In some embodiments, by detecting the indoor temperature of the air conditioning equipment in the current mode in real time, temperature values of the indoor temperature in different modes can be obtained.

[0055] In some embodiments, the target temperature in the current mode may be the temperature value of the target temperature set by the user for the current mode, and different temperature values may be set in different modes. For example, in the cooling mode, the user may set the target temperature to 10 degrees Celsius or 5 degrees Celsius, etc., and in the heating mode, the user may set the target temperature to 20 degrees Celsius to 30 degrees Celsius, etc. The specific temperature value can be custom-set by the user, and the present disclosure does not limit this.

[0056] In some embodiments, the preset condition may be set according to different air conditioning equipment or working conditions, and the preset condition may be the same or different in different modes, and the present disclosure does not limit this.

[0057] In some embodiments, when the current mode is the cooling mode, the preset condition is that the first difference within the first time period is less than or equal to the first value; when the current mode is the heating mode, the preset condition is that the first difference within the second time period is less than or equal to the second value, where the first value is an integer and the second value is a negative number.

[0058] In some embodiments, when the current mode is the cooling mode, the criterion for determining whether the environmental parameters reach the target state may be that the first difference between the indoor temperature and the target temperature continuously remains less than or equal to the first value within the first time period, where the first time period and the first value can be arbitrarily set values. For example, the first time period can be 5 minutes and the first value can be 2 degrees Celsius. In other words, after the user selects the cooling mode, the air conditioning device continuously detects and determines the difference between the indoor temperature and the target temperature set by the user. When this difference continuously remains less than or equal to 2 degrees Celsius within 5 minutes, the environmental parameters of the air conditioning device reach the target state.

[0059] In some embodiments, when the current mode is the heating mode, the criterion for determining whether the environmental parameters reach the target state may be that the first difference between the indoor temperature and the target temperature continuously remains less than or equal to the second value within the second time period, where the second time period and the second value can be arbitrarily set values. For example, the second time period can be 5 minutes and the second value can be -3 degrees Celsius. In other words, after the user selects the heating mode, the air conditioning device continuously detects and determines the difference between the indoor temperature and the target temperature set by the user. When this difference continuously remains less than or equal to -3 degrees Celsius within 5 minutes, the environmental parameters of the air conditioning device reach the target state.

[0060] In some embodiments, the first time period in the cooling mode and the second time period in the heating mode can be set to different lengths or the same length, and the present disclosure does not limit this.

[0061] Exemplarily, as Figure 5A shown, after starting up and running, it is determined whether the air conditioner enters the temperature-reached and frequency-reduced control. If so, frequency reduction control and low-load control mode are performed.

[0062] Exemplarily, Figure 5C shown, after starting up, the operating mode of the air conditioner is determined. In the cooling mode: (1) Real-time detection of parameters: the air volume gear P of the air conditioner; the indoor temperature T 内环 and T 设定 the difference △T between the temperatures; the louver angle. (2) When it is continuously detected that △T ≤ 2°C for 5 minutes, this function is entered. In the heating mode: (1) Real-time detection of parameters: the air volume gear P of the air conditioner; the indoor temperature T 内环 and T 设定 the difference △T between the temperatures; the louver angle. (2) When it is continuously detected that △T ≤ -3°C for 5 minutes, this function is entered.

[0063] In some embodiments, when the environmental parameters of the air conditioning device reach the target state, the current inner pipe temperature is obtained. Among them, the current inner pipe temperature can be the evaporator pipe temperature of the air conditioning device and can be measured by a sensor arranged on the evaporator.

[0064] In some embodiments, when the environmental parameters of the air conditioning device reach the target state, the current air volume setting is obtained. Here, the current air volume setting is the air volume value set by the user when setting the current mode. In different embodiments, the values of the current air volume setting can be the same or different. For different modes, the user can set different air volume values or the same air volume value; alternatively, in the case where the user does not actively set the air volume value, the system can use the default air volume value, which is set by the technician.

[0065] Step 202: Based on the current inner pipe temperature and / or the current air volume setting, adjust the air deflector angle of the air conditioning device to the target angle so that the recycled air volume of the air conditioning device reaches the target value. In some embodiments, when the air deflector angle of the air conditioning device is adjusted to the target angle, the angle between the air outlet direction of the air conditioning device and the installation surface of the air conditioning device reaches the target angle, and the air outlet of the air conditioning device returns to the interior of the air conditioning device through the air return opening provided at the bottom of the air conditioning device. In other words, by adjusting different target angles, the amount of air recycled through the air return opening can reach different target values, so as to achieve the recycling of hot and cold air for different inner pipe temperatures, or for different air volume settings, send the air volume to the user activity area, reduce air volume loss, and improve indoor comfort under different air volume settings.

[0066] In some embodiments, based on the current inner pipe temperature, adjust the air deflector angle of the air conditioning device to the target angle so that the recycled air volume of the air conditioning device reaches the target value. Among them, according to different inner pipe temperatures, different target angles can be set, and different ranges of target values can be set. For example, the larger the target angle, the smaller the target value of the recycled air volume, so as to send the air outlet of the air conditioning device to the target range and avoid being recycled by the air conditioning device; the smaller the target angle, the larger the target value of the recycled air volume, so that most of the air volume is recycled, reducing the influence on the indoor temperature corresponding to the air conditioning device.

[0067] In some embodiments, when the environmental parameters of the air conditioning device reach the target state, the air conditioning device has achieved the target demand for the indoor temperature. At this time, the operating frequency of the air conditioning device can be reduced, and at the same time, according to the inner pipe temperature, the air deflector angle is adjusted to send the hot and cold air of the air conditioning device back to the air return opening of the air conditioning device, reducing the influence of the air conditioning device on the indoor load, and adjusting the air deflector angle according to the change of the inner pipe temperature to control the input of the indoor load and improve the control range of the air conditioning device for low load.

[0068] In the above embodiments, when controlling the input of the indoor load during the operation of the indoor unit of the air conditioning device, the intelligent control of the air conditioning device's capacity is realized by recycling part of the air outlet, reducing the input of the indoor capacity, expanding the adjustment capacity of the air conditioner under low load, reducing the indoor temperature fluctuation, and improving the comfort of the user's indoor experience.

[0069] In some embodiments, based on the current wind speed setting, the air deflector angle of the air conditioning device is adjusted to a target angle so that the recycled air volume of the air conditioning device reaches a target value. Among them, for different wind speed settings, different target angles can be set, and different target values can be set for different target angles. The present disclosure does not limit this.

[0070] In some embodiments, for different modes, the target angles and target values corresponding to different wind speed settings can be set respectively. For example, in the cooling mode, since cold air is heavier, the greater the wind speed setting, the smaller the target angle, so as to avoid direct blowing of cold air on the human body, send the cold air to the user's activity area, and reduce cold air loss; for the heating mode, since hot air is lighter and the blown hot air will float upward, the greater the wind speed setting, the smaller the set target angle, so as to send the heat to the user's activity area and reduce heat loss.

[0071] In the above embodiments, the wind speed setting of the air conditioning device is combined with the air deflector for control. According to the different characteristics of cold air and hot air, different values are set for the angle of the air deflector to improve the problem of poor indoor comfort under different wind speed settings and enhance the user's comfort.

[0072] In summary, the control method of the air conditioning device proposed by the present disclosure can adjust the air deflector angle based on the change of the inner tube temperature when the environmental parameters reach the target state, so as to realize recycling part of the air output and reducing the impact of the air conditioning device on the indoor load; or adjust the air deflector angle based on different wind speed settings to improve the air supply uniformity under different wind speed settings, thereby enhancing the user's comfort.

[0073] Figure 3 FIG. is a schematic flow chart of adjusting the air deflector angle based on the inner tube temperature proposed by the embodiment of the present disclosure. Based on Figure 2 the embodiments shown, Figure 3 step 202 is further defined as follows. As Figure 3 shown, the method includes the following steps:

[0074] Step 301, lower the operating frequency of the air conditioning device to the target frequency.

[0075] In some embodiments, the target frequency can be the lowest operating frequency of the air conditioning device. For different air conditioning devices, their lowest operating frequencies can be different. For air conditioning devices produced by different manufacturers, their lowest operating frequencies that can be achieved can also be different. The present disclosure does not limit this.

[0076] Exemplarily, after starting up and running, it is judged whether the air conditioner enters the temperature-reached frequency-down control. If so, the frequency-down operation is preferentially executed until the compressor operates at the lowest frequency.

[0077] In the above embodiments, reducing the operating frequency of the air conditioning equipment can enable the air conditioning equipment to operate under low load. Since the current indoor temperature has reached the target state, reducing the operating frequency can reduce the energy consumption of the air conditioning equipment.

[0078] Step 302: In response to the air conditioning equipment operating at the target frequency for a preset duration, adjust the air deflector angle downward to a third angle, and determine the first temperature change rate of the inner pipe temperature of the air conditioning equipment within the first duration.

[0079] In some embodiments, the preset duration and the first duration can be pre-set time lengths, which can be customized according to different working conditions or different air conditioning equipment, and the present disclosure does not limit this.

[0080] In some embodiments, the preset duration can be 1 minute. When the air conditioning equipment starts to operate at the target frequency, the change in its inner pipe temperature is small. Therefore, there is no need to perform low-load control when starting to operate at a low frequency.

[0081] In some embodiments, low-load control includes adjusting the air deflector angle, and also includes controlling the compressor at a low frequency, reducing the rotational speed of the inner fan, adjusting the target inner pipe temperature, etc., and the present disclosure does not limit this. Among them, adjusting the target inner pipe temperature can be to increase the target inner pipe temperature in the cooling mode and decrease the target inner pipe temperature in the heating mode. The target inner pipe temperature is calculated based on different working conditions and the current parameters of the air conditioning equipment, or can also be directly obtained as a calculated value, and the present disclosure does not limit this.

[0082] In some embodiments, after the air conditioning equipment operates at the target frequency for a duration reaching the preset duration, control the air conditioning equipment to enter low-load control, that is, first adjust the air deflector downward to the third angle, and continuously detect the first temperature change rate of the adjusted inner pipe temperature within the first duration.

[0083] In some embodiments, the first temperature change rate can be the temperature change rate of the inner pipe temperature within the first duration, that is, divide the difference between the second inner pipe temperature corresponding to the end time point of the first duration and the first inner pipe temperature corresponding to the start time point of the first duration by the first inner pipe temperature to obtain the first temperature change rate.

[0084] In some embodiments, the first duration can be 30 seconds. In other words, judge the change rate of the inner pipe temperature within 30 seconds to quickly identify the state of the air conditioning equipment and adjust the air deflector angle.

[0085] In some embodiments, the third angle can be within the range of [30°, 45°]. In different embodiments, different angle values can be set for different working conditions or different air conditioning equipment, and the present disclosure does not limit this.

[0086] Exemplarily, after operating at the minimum operating frequency condition of the compressor for 1 minute, enter the low-load control mode. As Figure 5B shown in the schematic diagram of the low-load angle control of the top-air outlet type air conditioner. The air deflector angle automatically operates at the low-load angle 1, and continuously detects the change rate of the temperature of the inner pipe of the air conditioner.

[0087] Step 303, adjust the air deflector angle to the target angle based on the first temperature change rate.

[0088] In some embodiments, when the first temperature change rate satisfies the first condition, the air deflector angle is adjusted downward from the third angle to the fourth angle, and the second temperature change rate of the inner pipe temperature of the air conditioning equipment within the first time period is determined.

[0089] In some embodiments, the first condition may be that the first temperature change rate is less than or equal to 0.3 °C / min. In other words, if the change rate of the inner pipe temperature of the air conditioning equipment is small at the third angle, the air deflector angle needs to be further adjusted to increase the change of the inner pipe temperature, so as to ensure the output of the indoor load and maintain the indoor temperature under low-load operation.

[0090] In some embodiments, the fourth angle may be within the range of [20°, 30°]. In different embodiments, different angle values may be set for different working conditions or different air conditioning equipment, and the present disclosure does not limit this.

[0091] Exemplarily, as Figure 5B shown, when it is detected that the change of the inner pipe temperature of the air conditioner does not exceed 0.3 °C / min within 30 s, continue to adjust the air deflector angle, continue to adjust the low-load angle 2 of the air deflector, and continuously detect the change rate of the inner pipe temperature of the air conditioner.

[0092] In some embodiments, when the second temperature change rate satisfies the second condition, the air deflector angle is adjusted downward from the fourth angle to the fifth angle.

[0093] In some embodiments, the second condition may be less than or equal to 0.5 °C / min. In other words, if the change rate of the inner pipe temperature of the air conditioning equipment is small at the fourth angle, the air deflector angle needs to be further adjusted to increase the change of the inner pipe temperature, so as to ensure the output of the indoor load and maintain the indoor temperature under low-load operation.

[0094] In some embodiments, the fifth angle may be within the range of [10°, 20°]. In different embodiments, different angle values may be set for different working conditions or different air conditioning equipment, and the present disclosure does not limit this.

[0095] In some embodiments, the fifth angle may be 10°. That is, when the angle between the air deflector and the mounting surface is 10°, the air outlet direction of the air conditioning device is 80° horizontally downward, so that the air flow blows towards the air return opening. As a result, most of the air volume is recycled, reducing the load of the air conditioning device, expanding the adjustment ability of the air conditioning device under low load, and improving the comfort of indoor users.

[0096] In some embodiments, the value ranges of the third angle, the fourth angle, and the fifth angle can be defined according to different working conditions or different air conditioning devices. The specific values thereof are not limited in the present disclosure, and the value ranges in the present disclosure are only taken as one embodiment.

[0097] Exemplarily, after adjusting the air deflector to the low load angle 2, continuously detect the change rate of the temperature of the inner pipe of the air conditioner. When it is detected that the temperature of the inner pipe of the air conditioner changes no more than 0.5 °C / min within 30 s, continue to adjust the angle of the air deflector to the low load angle 3.

[0098] In some embodiments, when the first temperature change rate does not meet the first condition, or the second temperature change rate does not meet the second condition, or the angle of the air deflector is the fifth angle, determine the second difference between the indoor temperature corresponding to the air conditioning device and the target temperature within the second time period.

[0099] In some embodiments, when the first temperature change rate does not meet the first condition, that is, at the third angle, the air conditioning device can meet the output of the indoor load, then maintain the third angle and determine the second difference between the indoor temperature corresponding to the air conditioning device and the target temperature within the second time period.

[0100] In some embodiments, the second time period may be 10 minutes. In different embodiments, for different working conditions or different air conditioning devices, the value of the second time period may be the same or different, which is not limited in the present disclosure.

[0101] In some embodiments, determining the second difference between the indoor temperature corresponding to the air conditioning device and the target temperature within the second time period may be calculating the difference between the indoor temperature and the target temperature at a fixed frequency within the second time period, and taking the average or median of the differences calculated within the second time period.

[0102] In some embodiments, the second difference may be the difference between the indoor temperature corresponding to the end time point of the second time period and the target temperature.

[0103] Exemplarily, the air deflector angle automatically operates at the low load angle 1: Continuously detect the change rate of the temperature of the inner pipe of the air conditioner. When it is detected that the temperature of the inner pipe of the air conditioner changes more than 0.3 °C / min within 30 s, it is determined that the control of the low load angle 1 is normal, and the air conditioner operates continuously for 10 min to evaluate the change of the indoor load.

[0104] In some embodiments, when the second temperature change rate does not meet the second condition, that is, at the fourth angle, if the air conditioning device can meet the output of the indoor load, the fourth angle is maintained, and the second difference between the indoor temperature corresponding to the air conditioning device and the target temperature within the second duration is determined.

[0105] Exemplarily, after adjusting the air deflector to the low load angle 2, continuously detect the temperature change rate of the inner pipe of the air conditioner. When it is detected that the temperature of the inner pipe of the air conditioner changes by more than 0.5 °C / min within 30 s, it is determined that the low load angle 2 control is normal, and the air conditioner runs continuously for 10 min to evaluate the change of the indoor load.

[0106] In some embodiments, when the air deflector angle is at the fifth angle, determine the second difference between the indoor temperature corresponding to the air conditioning device and the target temperature within the second duration, that is, the air deflector angle is adjusted to the minimum angle in the low load control, and judge the difference between the indoor temperature and the target temperature of the air conditioning device at the minimum angle.

[0107] Exemplarily, after the air deflector angle is adjusted to the low load angle 3, the air conditioner runs continuously for 10 min to evaluate the change of the indoor load.

[0108] In some embodiments, when the second difference does not meet the target range, determine the third temperature change rate of the inner pipe temperature of the air conditioning device within the first duration; based on the third temperature change rate, adjust the air deflector angle to the target angle.

[0109] In some embodiments, the target range can be a pre-set range of the indoor load under low load control, for example, △t ∈ (-0.5 °C, 0.5 °C), where △t represents the difference between the indoor temperature and the target temperature.

[0110] In some embodiments, if after the air deflector angle is adjusted to the third angle or the fourth angle or the fifth angle, the second difference between the indoor temperature and the target temperature within the second duration does not meet the target range, re-perform low load control on the air deflector angle, that is, determine the third temperature change rate of the current inner pipe temperature within the first duration, so as to adjust the air deflector angle to the target angle according to the third temperature change rate. Among them, the specific manner of adjusting the air deflector angle to the target angle according to the third temperature change rate is as described in the control manners in steps 302 and 303, which will not be elaborated here.

[0111] In some embodiments, when the second difference meets the target range, maintain the air deflector angle at the third angle or the fourth angle or the fifth angle.

[0112] In some embodiments, when the air deflector angle is adjusted to the third angle, the first temperature change rate does not meet the first condition, and the second difference meets the target range, then the third angle remains unchanged.

[0113] In some embodiments, when the air deflector angle is adjusted to the fourth angle, if the second temperature change rate does not meet the second condition and the second difference meets the target range, the fourth angle is kept unchanged.

[0114] In some embodiments, when the air deflector angle is adjusted to the fifth angle and the second difference meets the target range, the fifth angle is kept unchanged.

[0115] Exemplarily, when it is detected that the temperature change rate of the air conditioner's inner pipe meets the temperature change requirements of each stage, the air conditioner operates continuously for 10 minutes to evaluate the change of the indoor load. When △t ∈ (-0.5°C, 0.5°C), the current control parameters are maintained unchanged.

[0116] In some embodiments, when the air conditioner device is shut down, switches the current mode, or stops due to a fault, the above control method is exited. In other words, it can be exiting the low-load control mode to re-judge the environmental parameters of the air conditioner device after the air conditioner device is turned on.

[0117] In summary, the angle of the air deflector of the air conditioner device can be in the range of [10°, 45°].

[0118] In the above embodiments, the air deflector of the upper return air and lower outlet air structure type of the air conditioner indoor unit is gradually adjusted according to the change rate of the inner pipe temperature to control the indoor load output of the air conditioner, expand the adjustment ability of the air conditioner under low load, and further improve the comfort of indoor users.

[0119] Figure 4 It is a schematic flowchart of adjusting the air deflector angle based on the wind gear proposed in the embodiments of the present disclosure. Based on Figure 2 the embodiments shown, Figure 4 step 202 is further defined as, as Figure 4 shown, the method includes at least one of the following steps:

[0120] In the embodiments of the present disclosure, the gear range is divided into a first gear range, a second gear range, a third gear range, or a fourth gear range. In different modes, the adjustment angles of the air deflector angles corresponding to the gear ranges can be the same or different.

[0121] In some embodiments, the gear values in the first gear range, the second gear range, the third gear range, or the fourth gear range increase in sequence; the larger the gear value of the current wind gear, the smaller the adjustment angle of the air deflector angle; the value of the adjustment angle corresponding to the current cooling mode is smaller than the value of the adjustment angle corresponding to the current heating mode.

[0122] In some embodiments, the first gear range is gear 1 or gear 2, the second gear range is gears 3 to 5, and the third gear range or the fourth gear range is gear 6 and above.

[0123] In some embodiments, since the weight of the hot air is less than that of the cold air, in the heating mode, the outgoing air will float upward, while in the cooling mode, the outgoing air will fall downward. Therefore, when the gear value of the current air duct is larger, the adjustment angle corresponding to the heating mode should be greater than the adjustment angle corresponding to the cooling mode, so that the hot air can be blown to the target area, avoiding the direct upward floating of the hot air due to too small an angle adjustment, so that the target area cannot reach the target temperature in a short time.

[0124] The following is an example of the adjustment process of the air deflector angle for the current air duct in different gear ranges. The following steps are executed separately in different situations:

[0125] Step 401, when the current air duct is in the first gear range, adjust the air deflector angle to a preset angle.

[0126] In some embodiments, the first gear range can be greater than or equal to 1 gear and less than or equal to 2 gears.

[0127] In some embodiments, the preset angle can be the angle corresponding to a preset fixed mode. For different air conditioner devices, the value of the preset angle can be set arbitrarily within the range of [30°, 50°]. In particular, it can be 45°.

[0128] In some embodiments, when the preset angle is 50°, the included angle between the air deflector of the air conditioner device and the installation surface is 40 degrees. The air conditioner device blows air through the fan-shaped area between the air deflector and the installation surface, so that the outgoing air can rush towards the ground. Since the outgoing air rushes towards the ground, most of the outgoing air can be recycled by the air outlet, achieving the purpose of air volume recycling and reducing the energy consumption of the air conditioner device.

[0129] In some embodiments, the preset angle can be 45° downward of the air deflector, so that the outgoing air area faces the user activity area to avoid energy loss. It should be noted that for air conditioner devices with different structures, the names of the angles that can achieve the above functions may be different, and the opening angles of the air deflectors may also be different.

[0130] In some embodiments, the definition of the above preset angle is for air conditioner devices with an upper air outlet and lower air return structure, and the air deflector is a large air deflector, that is, the area of the air deflector is larger than the area of the air deflectors configured on most air conditioner devices.

[0131] In some embodiments, when the current air duct is in the first gear range, adjusting the air deflector angle to the preset angle can be in the heating mode or the cooling mode. When the air duct is in gear 1 or gear 2, directly adjust the air deflector angle to 45° downward, so that the outgoing air area of the air conditioner device faces the user activity area and avoids energy loss.

[0132] Exemplarily, in the cooling mode, at wind speeds of 1 to 2, the air deflector is directly adjusted to the carpet air angle; in the heating mode, at wind speeds of 1 to 2, the air deflector is directly adjusted to the carpet air angle.

[0133] In the above embodiments, when the current wind speed is within the first gear range, that is, when the air volume output of the air conditioner is small, the angle of the air deflector is adjusted to a preset angle, which can expand the air supply range. At this time, the target value of the recycled air volume of the air conditioner can be set to zero or a small value. In other words, at the preset angle, cold air or hot air can be directly sent to the user's activity area, thereby achieving cooling or heating of the user's activity area and avoiding being recycled by the air return opening.

[0134] Step 402, when the current wind speed is within the second gear range, the angle of the air deflector is adjusted downward by a first angle and then adjusted from the first angle to the preset angle.

[0135] In some embodiments, the second gear range can be greater than or equal to 3 and less than or equal to 5.

[0136] In some embodiments, the first angle can be set within a first range, where the first range can be set to different values in different modes.

[0137] In some embodiments, in the cooling mode, the first range can be [5, 10] degrees. The first angle can be set to 5 degrees in the cooling mode, or can also be set to 8 degrees, 10 degrees, etc., and can be defined according to different working conditions, different air conditioners or different requirements.

[0138] Specifically, when the first angle is 5 degrees, the air deflector of the air conditioner is adjusted downward by 5°, then the included angle between the air deflector and the installation surface is 85°. Thus, the air conditioner can blow air through the fan-shaped area between the air deflector and the installation surface. Due to the increased air supply range, the air volume can directly reach the area where the user is located, avoiding the air being recycled by the air return opening.

[0139] In some embodiments, in the heating mode, the first range can be [10, 20] degrees. The first angle can be set to 10 degrees in the heating mode, or can also be set to 15 degrees, 20 degrees, etc., and can be defined according to different working conditions, different air conditioners or different requirements.

[0140] In some embodiments, when the current wind speed is within the second gear range, adjusting the angle of the air deflector downward by the first angle can be to first determine whether the current angle of the air deflector is the first angle. If so, there is no need to adjust the angle of the air deflector. Otherwise, the angle of the air deflector is adjusted downward by the first angle. In other words, the body of the air deflector is rotated downward by the first angle along the connection with the air conditioner.

[0141] In some embodiments, when in the refrigeration mode and the current wind speed is in the second gear range, the air deflector angle is adjusted downward by a first angle and adjusted from the first angle to a preset angle. For example, in the refrigeration mode, when the wind speed is in the range of [3, 5], the air deflector is rotated downward by any value within [5, 10] degrees and continues to rotate downward until the included angle with the vertical direction is 45 degrees.

[0142] Exemplarily, in the refrigeration mode, when the wind speed is in the range of 3 - 5, the air deflector is adjusted downward by an angle a until the carpet air angle is reached.

[0143] In some embodiments, when in the heating mode and the current wind speed is in the second gear range, the air deflector angle is adjusted downward by a first angle and adjusted from the first angle to a preset angle. For example, in the heating mode, when the wind speed is in the range of [3, 5], the air deflector is rotated downward by any value within [10, 20] degrees and continues to rotate downward until the included angle with the vertical direction is 45 degrees.

[0144] Exemplarily, in the heating mode, when the wind speed is in the range of 3 - 5, the air deflector is adjusted downward by an angle 2a until the carpet air angle is reached.

[0145] In the above embodiments, in the refrigeration mode and the heating mode, the value of the first angle is different. Specifically, the first angle in the heating mode is greater than that in the refrigeration mode. The main reason is that the weight of cold air is relatively greater than that of hot air, and hot air floats more severely in the heating mode than cold air in the refrigeration mode. Therefore, in order to suppress the air outlet, a larger angle needs to be adjusted downward to ensure that the included angle between the air outlet direction and the installation surface is smaller, so as to meet the requirement of delivering air to the area needed by the user.

[0146] In the above embodiments, in the refrigeration mode, due to the greater weight of cold air, the set first angle is relatively small, and the target value corresponding to the recycled air volume of the air conditioning device is also small. For example, it can be set to zero or a small value, that is, the angle at which the air deflector opens downward is small, and correspondingly, the recycled air volume will also be small; in the heating mode, due to the upward floating of hot air, the set first angle is relatively large, and the target value corresponding to the recycled air volume of the air conditioning device is still small. For example, it can also be set to zero or a small value, that is, the angle at which the air deflector opens downward is large, but due to the upward floating of hot air, the recycled air volume will also be small. In summary, the target value can be custom - set according to the actual working conditions or different air conditioning devices, and can be set to the minimum value in the experimental data, or the minimum value in the actual parameters, etc.

[0147] Step 403, when the current wind speed is in the third gear range, keep the air deflector angle of the air conditioning device at the current angle and maintain the current inner pipe temperature of the air conditioning device unchanged.

[0148] In some embodiments, the third gear range can be greater than or equal to 6 gears.

[0149] In some embodiments, in the cooling mode, when the current wind speed gear is 6 or above, keep the air deflector angle of the air conditioner equipment at the current angle, that is, maintain the original state unchanged, and keep the current inner pipe temperature unchanged.

[0150] Exemplarily, in the cooling mode, when the wind speed gear is 6 or above, the air deflector maintains the original state and the target pipe temperature remains unchanged.

[0151] In the above embodiments, in the cooling mode, if the wind speed gear is relatively high, that is, greater than or equal to 6 or above, the air deflector angle is not adjusted. At this time, due to the high wind speed gear, the frequency is also high, the cooling capacity is large, and the indoor demand for the air conditioner is also large. At this time, in order to quickly reduce the indoor temperature, a large air volume and a large cooling capacity are required. Adjusting the air deflector will affect the air output volume and cause condensation problems. Therefore, the air conditioner equipment operates according to the original plan. Among them, the condensation problem may be due to uneven alternating of heat and cold on the surface of the air deflector, resulting in condensation and affecting the user experience.

[0152] In the above embodiments, in the cooling mode, when the wind speed gear is large, the air deflector angle is not adjusted. On the one hand, it can quickly achieve indoor cooling, and on the other hand, it can avoid the condensation problem caused by adjusting the air deflector. Thus, the target value corresponding to the recycled air volume of the air conditioner equipment can be set to the intermediate value or average value or maximum value, etc. of the experimental data. In other words, in this case, since the wind speed gear is large, the recycled air volume can be not restricted, mainly to achieve quick cooling so that the indoor temperature reaches the target temperature.

[0153] Step 404, when the current wind speed gear is in the fourth gear range, adjust the air deflector angle downward by a second angle and adjust it from the second angle to the preset angle.

[0154] In some embodiments, the fourth gear range may be greater than or equal to 6 gears.

[0155] In some embodiments, the second angle may take any value within a second range, and the second range may be [5, 10] degrees.

[0156] In some embodiments, when the current wind speed gear is in the fourth gear range, determine whether the current air deflector angle is the second angle. If so, continue to adjust from the current air deflector angle to the preset angle; if it is not the second angle, rotate the air deflector downward along the connection by the second angle and continue to adjust from the second angle to the preset angle.

[0157] In some embodiments, in the heating mode, when the current wind speed gear is 6 or above, adjust the air deflector angle downward by a second angle and continuously adjust the air deflector angle until the preset angle. It may be that in the heating mode, when the wind speed gear is 6 or above, adjust the air deflector angle downward by any value within [5, 10] degrees and continue to adjust downward from this angle until the preset angle.

[0158] Exemplarily, in the heating mode, when the wind speed is at gear 6 or above, the air deflector is adjusted downward by an angle a until the carpet air angle is reached.

[0159] In the above embodiment, when the wind speed in the heating mode is relatively high, the adjustment angle of the air deflector can be set to a relatively small angle to prevent the hot air from being recycled, so that the target value corresponding to the recycled air volume of the air conditioning device can be set to zero or a small value.

[0160] Step 405, when the angle of the air deflector is adjusted to the preset angle, or during the process of adjusting the angle of the air deflector towards the preset angle, the current inner pipe temperature of the air conditioning device is adjusted within the preset correction range until the difference between the current indoor temperature and the target temperature reaches zero.

[0161] In some embodiments, in any one of steps 401 to 404, after the angle of the air deflector is adjusted to the preset angle, or during the process of adjusting the angle of the air deflector towards the preset angle, the correction of the target pipe temperature can be combined to make the difference between the indoor temperature of the air conditioning device and the target temperature reach zero.

[0162] In some embodiments, under different modes, the preset correction ranges of the current inner pipe temperature corresponding to different wind speeds are different. Specifically, in the cooling mode, the preset correction range is less than 0 degrees. The lower the wind speed, the smaller the cooling capacity output by the air conditioning device. To meet the indoor load requirements, at the same air volume, the lower the inner pipe temperature, the greater the cooling capacity and the stronger the load adjustment ability, and it can better meet the changes in indoor load; in the heating mode, the preset correction range is greater than 0 degrees. The lower the wind speed, the smaller the heating capacity output by the air conditioning device. To meet the indoor load requirements, at the same air volume, the higher the inner pipe temperature, the greater the heating capacity and the stronger the load adjustment ability, and it can better meet the changes in indoor load.

[0163] In some embodiments, in the cooling mode, when the current wind speed is in the third gear range, the preset correction range is zero; when the current wind speed is in the second gear range, the preset correction range is [-0.5, 0)°C; when the current wind speed is in the first gear range, the preset correction range is [-1, 0)°C.

[0164] Exemplarily, in the cooling mode, when the wind speed is in gears 3 to 5, the air deflector is adjusted downward by an angle a until the carpet air angle is reached, and the target pipe temperature is corrected by -0.5°C; when the wind speed is in gears 1 to 2, the air deflector is directly adjusted to the carpet air angle, and the target pipe temperature is corrected by -1°C.

[0165] In some embodiments, in the heating mode, when the current wind speed gear is in the fourth gear range, the preset correction range is (0, +0.5] °C; when the current wind speed gear is in the second gear range, the preset correction range is (0, +1] °C; when the current wind speed gear is in the first gear range, the preset correction range is (0, +2] °C.

[0166] Exemplarily, in the heating mode, when the wind speed gear is 6 or above, the air deflector is adjusted downward by an angle a until the carpet air angle, and the target pipe temperature is corrected by +0.5 °C; when the wind speed gear is 3-5, the air deflector is adjusted downward by an angle 2a until the carpet air angle, and the target pipe temperature is corrected by +1 °C; when the wind speed gear is 1-2, the air deflector is directly adjusted to the carpet air angle, and the target pipe temperature is corrected by +2 °C.

[0167] In summary, the target angle of the air deflector of the air conditioning device can be in the range of [40°, 85°].

[0168] In the above embodiments, when the environmental parameters of the air conditioning device reach the target state, by combining the wind speed gear with the air deflector of the air conditioning device, the air outlet effect of the air conditioning device in different wind speed gears is improved, thereby improving the indoor comfort; at the same time, the temperature of the inner pipe can be corrected to better achieve the target temperature of the indoor environment set by the user and improve the user's comfort.

[0169] Based on Figure 3 、 Figure 4 the embodiments shown, the adjustment angle of the air deflector is in the range of [10°, 85°].

[0170] In summary, the control method of the air conditioning device proposed by the present disclosure can, when the environmental parameters reach the target state, adjust the angle of the air deflector by detecting the temperature of the inner pipe or the wind speed gear, so that the air volume recovered by the air conditioning device reaches the target value, which can not only meet the user's needs, but also reduce the air conditioning load and improve the user's comfort.

[0171] The following are specific embodiments of the control method of the air conditioning device:

[0172] Embodiment 1: An air deflector control method based on changes in indoor heating and cooling loads.

[0173] As Figure 5A shown, it is a schematic diagram of the control flow. For the air conditioner indoor unit with the structure of lower air return and upper air outlet, the large air deflector control is adopted, which can effectively adjust the up and down angles of the air supply, send the hot and cold air of the air conditioner back to the air return opening of the air conditioner, reduce the influence of the air conditioner on the indoor load, and adjust the angle of the air deflector according to the change of the indoor load, control the input of the indoor load, improve the control range of the air conditioner for low loads, and improve the comfort of the user indoors.

[0174] As Figure 5A shown, it includes the following steps:

[0175] 1. After starting up and running, determine whether the air conditioner enters the temperature-reached and frequency-down control. If so, execute step 2; if not, continuously determine whether to enter the temperature-reached and frequency-down control.

[0176] 2. Give priority to executing the frequency-down action until the compressor runs at the lowest frequency.

[0177] 3. After running for 1 minute when the condition of the lowest operating frequency of the compressor is met, enter the low-load control mode.

[0178] 4. As Figure 5B shown in the schematic diagram of the low-load angle control of the top-air outlet type air conditioner.

[0179] The air deflector angle automatically runs at the low-load angle 1: Continuously detect the change rate of the temperature of the inner pipe of the air conditioner. When it is detected that the temperature of the inner pipe of the air conditioner changes by more than 0.3 °C / min within 30 s, it is determined that the low-load angle 1 control is normal; otherwise, continue to adjust the air deflector angle.

[0180] Continue to adjust the air deflector to the low-load angle 2: Continuously detect the change rate of the temperature of the inner pipe of the air conditioner. When it is detected that the temperature of the inner pipe of the air conditioner changes by more than 0.5 °C / min within 30 s, it is determined that the low-load angle 2 control is normal; otherwise, continue to adjust the air deflector angle until the low-load angle 3.

[0181] When the change rate of the temperature of the inner pipe of the air conditioner meets the temperature change requirements of each stage, the air conditioner runs continuously for 10 min, evaluates the change of the indoor load. When △t ∈ (-0.5 °C, 0.5 °C), keep the current control parameters unchanged.

[0182] 5. When the air conditioner equipment shuts down / switches modes / fails to stop, exit the low-load control function.

[0183] The control method of Embodiment 1 controls the indoor load output of the air conditioner by adjusting the air deflector of the indoor unit of the air conditioner with the upper return air and lower air outlet structure, expands the adjustment ability of the air conditioner under low load, and improves the comfort of indoor users.

[0184] Embodiment 2: A control method for improving the indoor temperature uniformity based on different wind speeds.

[0185] In this solution, the air deflector is linked with the wind speed control. When it is detected that the indoor wind speed decreases, the air deflector angle is adjusted in a timely manner to avoid the deterioration of the indoor temperature uniformity caused by the decrease in air volume. At the same time, combined with the optimized control of the target pipe temperature, the indoor temperature fluctuation at different wind speeds is improved, and the indoor comfort of users is improved.

[0186] The main parameters involved in this solution include: the wind speed P of the indoor unit of the air conditioner, the air deflector angle (skylight wind, carpet wind, surround wind), and the inner ring temperature T 内环, Remote control set temperature T 设定 .

[0187] Figure 5C It is a flow schematic diagram of the second embodiment. As shown in Figure 5C shown, it includes the following steps:

[0188] 1. Turn on the machine and judge the air conditioner operation mode.

[0189] 2. In the cooling mode:

[0190] (1) Real-time detection parameters: the air duct gear P of the air conditioner; the indoor temperature T 内环 and T 设定 the temperature difference △T; the air deflector angle.

[0191] (2) When it is continuously detected that △T ≤ 2°C for 5 minutes, enter this function.

[0192] (3) When the air duct gear is 6th gear or above, the air deflector remains unchanged, and the target pipe temperature remains unchanged;

[0193] When the air duct gear is 3 - 5th gear, the air deflector is adjusted downward by an angle a until the carpet air angle, and the target pipe temperature is corrected by -0.5°C;

[0194] When the air duct gear is 1 - 2nd gear, the air deflector is directly adjusted to the carpet air angle, and the target pipe temperature is corrected by -1°C.

[0195] 3. In the heating mode:

[0196] (1) Real-time detection parameters: the air duct gear P of the air conditioner; the indoor temperature T 内环 and T 设定 the temperature difference △T; the air deflector angle.

[0197] (2) When it is continuously detected that △T ≤ -3°C for 5 minutes, enter this function.

[0198] (3) When the air duct gear is 6th gear or above, the air deflector is adjusted downward by an angle a until the carpet air angle, and the target pipe temperature is corrected by +0.5°C;

[0199] When the air duct gear is 3 - 5th gear, the air deflector is adjusted downward by an angle 2a until the carpet air angle, and the target pipe temperature is corrected by +1°C;

[0200] When the air duct gear is 1 - 2nd gear, the air deflector is directly adjusted to the carpet air angle, and the target pipe temperature is corrected by +2°C.

[0201] In the above scheme, the value range of a can be [5, 10] degrees.

[0202] The control method of the second embodiment improves the problem of poor indoor comfort under different air duct gears by combining the air duct gear with the air deflector of the air conditioner, and improves the user's comfort in use.

[0203] In summary, the control methods of the first embodiment and the second embodiment can both adjust the angle of the air deflector when the environmental parameters of the air conditioner reach the target state, so as to control the recycled air volume of the air conditioner and improve the user's comfort.

[0204] Figure 6 FIG. 600 is a schematic structural diagram of a control device according to an embodiment of the present disclosure. As Figure 6 shown, the device includes:

[0205] A determination module 610, configured to determine the current inner pipe temperature and / or the current wind speed of the air conditioner in response to the environmental parameters of the air conditioner reaching the target state.

[0206] A control module 620, configured to adjust the angle of the air deflector of the air conditioner to a target angle based on the current inner pipe temperature and / or the current wind speed, so that the included angle between the air outlet direction of the air conditioner and the installation surface of the air conditioner reaches the target angle, the air conditioner blows air through the air outlet, and recovers part of the air volume through the air return port, so that the recycled air volume of the air conditioner reaches the target value, and the target angle is in the range of [10°, 85°].

[0207] In some embodiments, the determination module is further configured to: determine whether the environmental parameters of the air conditioner reach the target state. Wherein, determining whether the environmental parameters of the air conditioner reach the target state includes: detecting the indoor temperature of the air conditioner in the current mode in real time; determining that the environmental parameters of the air conditioner reach the target state when the first difference between the indoor temperature and the target temperature in the current mode meets a preset condition.

[0208] In some embodiments, when the current mode is the cooling mode, the preset condition is that the first difference within the first time period is less than or equal to the first value; when the current mode is the heating mode, the preset condition is that the first difference within the second time period is less than or equal to the second value, where the first value is an integer and the second value is a negative number.

[0209] In some embodiments, the control device can be configured in the following two ways:

[0212] In some embodiments of the present disclosure, the gear values in the first gear range, the second gear range, the third gear range or the fourth gear range increase in sequence; the larger the gear value of the current wind gear is, the smaller the adjustment angle of the air guide plate is; the value of the adjustment angle corresponding to the cooling mode when the current mode is smaller than the value of the adjustment angle corresponding to the heating mode when the current mode is.

[0213] In the above embodiment, when the environmental parameters of the air-conditioning equipment reach the target state, the wind gear is combined with the air guide plate of the air-conditioning equipment to improve the air outlet effect of the air-conditioning equipment at different wind gears, thereby improving the indoor comfort; at the same time, the inner tube temperature can be corrected to better achieve the indoor temperature to the user's target temperature, thereby improving the user's comfort.

[0214] Option 2:

[0215] In some embodiments, the control module is also used to: lower the operating frequency of the air-conditioning equipment to a target frequency; in response to the air-conditioning equipment running at the target frequency for a preset period of time, adjust the angle of the air guide plate downward to a third angle, and determine a first temperature change rate of the inner tube temperature of the air-conditioning equipment within the first period of time; based on the first temperature change rate, adjust the angle of the air guide plate to the target angle.

[0216] In some embodiments, the control module is also used to: when the first temperature change rate meets the first condition, adjust the angle of the air guide plate downward from the third angle to the fourth angle, and determine the second temperature change rate of the inner tube temperature of the air-conditioning equipment within the first time length; when the second temperature change rate meets the second condition, adjust the angle of the air guide plate downward from the fourth angle to the fifth angle.

[0217] In some embodiments, the control module is further configured to: determine a second difference between the indoor temperature corresponding to the air-conditioning device and the target temperature within a second duration when the first temperature change rate does not meet the first condition, or the second temperature change rate does not meet the second condition, or the air deflector angle is the fifth angle; when the second difference does not meet the target range, determine a third temperature change rate of the inner pipe temperature of the air-conditioning device within a first duration; and adjust the air deflector angle to the target angle based on the third temperature change rate.

[0218] In some embodiments, the control module is further configured to: maintain the air deflector angle at the third angle, or the fourth angle, or the fifth angle when the second difference meets the target range.

[0219] In some embodiments, the air-conditioning device has an upper-air outlet and lower-air return structure, the air outlet is arranged at the upper part of the side surface of the air-conditioning device or the upper surface of the air-conditioning device, and the air return port is arranged at the lower surface of the air-conditioning device; or the air-conditioning device has a lower-air outlet and upper-air return structure, the air outlet is arranged at the lower surface of the air-conditioning device or the lower part of the side surface of the air-conditioning device, and the air return port is arranged at the upper surface of the air-conditioning device or the upper part of the side surface of the air-conditioning device, wherein the width of the air deflector of the air-conditioning device is greater than one-third of the panel height of the air-conditioning device.

[0220] In the above embodiments, the air deflector angle of the air-conditioning device is gradually adjusted according to the change rate of the inner pipe temperature to control the indoor load output of the air conditioner, expand the adjustment ability of the air conditioner under low load, and further improve the comfort of indoor users.

[0221] In some embodiments, the target angle is in the range of [10°, 45°].

[0222] In some embodiments, the target angle is in the range of [40°, 85°].

[0223] In summary, the control device proposed in the present disclosure controls the air output of the air-conditioning device by associating the inner pipe temperature or the wind gear with the air deflector angle and adjusting the air deflector of the indoor unit of the air conditioner with the upper-air return and lower-air outlet structure, thereby improving the comfort of users.
