[0002] In modern life, an air conditioner is an essential device for indoor places, and the air conditioner can provide a comfortable living or working environment for users by controlling the indoor ambient temperature.

[0003] Generally, the operation modes of the air conditioner mainly include a cooling mode, a heating mode, a blowing mode, a defrosting mode and a self-cleaning mode. The blowing distance of the air conditioner can refer to the farthest distance reached by the cold wind, hot wind or natural wind blown by the air conditioner when the air conditioner is running.

[0004] In the prior art, the air conditioner usually blows air based on a built-in centrifugal fan or a cross-flow fan. The centrifugal fan has a large air pressure, and when the air conditioner blows air based on the built-in centrifugal fan, the blowing distance is relatively far, but the user's blowing feeling is strong, and the user's comfort experience is poor. The cross-flow fan has a small air pressure, and the user's blowing feeling is weak, but the blowing distance is relatively close. Moreover, the air speed of the traditional air conditioner blowing is usually fixed, and in actual scenarios, the fixed air speed blowing is usually difficult to achieve the best temperature regulation effect, and the regulation efficiency of the indoor ambient temperature is low.

[0051] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0052] In the description of the invention, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0053] Figure 1 is a flowchart of the control method of the air conditioner provided by the present application. The control method of the air conditioner provided by the present application will be described below in combination with Figure 1 The control method of the air conditioner provided by the present application will be described below in combination with Figure 1 As shown in the figure, the method comprises the following steps: in step 101, the running mode of the air conditioner and the temperature difference between the indoor environment temperature and the outdoor environment temperature are obtained in the case that the air conditioner is started.

[0054] The air conditioner comprises a plurality of blowing ports, and one air supplementing fan is arranged at each blowing port, and the air supplementing fan can rotate around the inner diameter of the corresponding blowing port.

[0055] It should be noted that the execution subject of the embodiment of the present application is the control device of the air conditioner.

[0056] It should be noted that the air conditioner in the embodiment of the present application can be used to regulate the indoor environment temperature.

[0057] The outdoor environment temperature refers to the outdoor environment temperature within a preset distance from the indoor environment, for example, the outdoor environment temperature can be the outdoor environment temperature within 10 meters from the indoor environment.

[0058] It should be noted that the control method of the air conditioner provided by the present application is applied to the air conditioner with a plurality of blowing ports. The air supply device in the air conditioner comprises a cross-flow fan and a plurality of air supplementing fans. One air supplementing fan is arranged at each blowing port, and the air supplementing fan can rotate around the inner diameter of the corresponding blowing port, and the air supplementing fan can also rotate relative to the first rotation axis. The first rotation axis is the central axis of the supporting structure in which the air supplementing fan is arranged, and the central axis is perpendicular to the plane in which the blowing port is located.

[0059] It should be noted that the conventional air conditioner usually blows air based on the built-in centrifugal fan or cross-flow fan. The centrifugal fan has large air pressure, and when the air conditioner blows air based on the built-in centrifugal fan, the blowing distance is relatively far, but the user's blowing feeling is strong, and the user's comfort experience is poor. The cross-flow fan has small air pressure, and the user's blowing feeling is weak, but the blowing distance is relatively close.

[0060] Since the cross-flow fan has the characteristics of long blowing distance but small air outlet range and weak blowing feeling of the user, the air supply device in the air conditioner in the embodiment of the present application comprises a cross-flow fan and a plurality of rotatable air supplement fans. Compared with the air conditioner adopting the centrifugal fan, the cross-flow fan can increase the blowing distance of the air conditioner, and meanwhile, the plurality of rotatable air supplement fans can increase the air outlet range of the air conditioner, so that the air outlet range of the air conditioner and the blowing distance of the air conditioner can be increased without increasing the blowing feeling of the human body.

[0061] Figure 2 is one of the perspective views of the air conditioner in the control method of the air conditioner provided by the present application. Figure 3 is the front view of the air conditioner in the control method of the air conditioner provided by the present application. Figure 4 is the sectional view of the air conditioner in the control method of the air conditioner provided by the present application. As shown in Figure 2 、 Figure 3 and Figure 4 , the air supply device in the air conditioner comprises a cross-flow fan 401 and a first number of air supplement fans 201.

[0062] The surface of the shell 203 of the air conditioner is provided with a first number of air outlets 204. The first number is not less than 2, and the embodiment of the present application takes the value of the first number as 2 as an example.

[0063] Each air outlet 204 is provided with an air supplement fan 201, and the air supplement fan 201 can rotate clockwise or counterclockwise around the inner diameter of the corresponding air outlet 204.

[0064] It should be noted that the structures of the air outlets 204 are the same, and the embodiment of the present application takes one air outlet 204 and the air supplement fan 201 arranged at the air outlet 204 as an object to describe the air conditioner and the control method of the air conditioner provided by the present application. The air outlet 204 and the air supplement fan 201 appearing in the following description can generally refer to any air outlet 204 in the air conditioner and the air supplement fan 201 arranged at the air outlet 204.

[0065] The air supplement fan 201 is rotationally connected with a support structure. In the embodiment of the present application, the central axis of the support structure perpendicular to the plane of the air outlet 204 can be taken as a first rotation axis, and the horizontal plane where the first rotation axis is located can be taken as a reference horizontal plane. The air supplement fan 201 can rotate relative to the first rotation axis. By controlling the rotation angle of the air supplement fan 201 relative to the first rotation axis, the direction of the air blown out or sucked in by the air supplement fan 201 can be controlled.

[0066] Optionally, the support structure can be a support frame, a support shaft or a support plate. The specific structure of the support structure is not limited in the embodiment of the present application.

[0067] Optionally, the air supplement fan 201 can comprise a filter screen, a fan blade and a rotating motor in an integrated design. The rotating motor can drive the fan blade to rotate in a clockwise direction or in an anticlockwise direction. The filter screen is arranged on the outer side of the fan blade and can be used to filter the air blown out or sucked in by the air supplement fan 201. The outer side of the fan blade refers to the side away from the shell 203.

[0068] Optionally, an annular gear mechanism 301 can be arranged in the shell 203 along the inner diameter of the air outlet 204. The diameter of the annular gear mechanism 301 is slightly larger than the diameter of the air outlet 204, and the difference between the diameter of the annular gear mechanism 301 and the diameter of the air outlet 204 is less than a preset value. The difference between the diameter of the annular gear mechanism 301 and the diameter of the air outlet 204 being less than the preset value can ensure that the diameter of the annular gear mechanism 301 is not too large. The specific value of the preset value can be determined based on prior knowledge, and the specific value of the preset value is not limited in the embodiment of the present application.

[0069] Correspondingly, the air supplement fan 201 can be fixedly connected to any point on the annular gear mechanism 301 through the support structure. The annular gear mechanism 301 is driven to rotate by the first stepping motor 207, and the annular gear mechanism 301 can further drive the support structure and the air supplement fan 201 connected to the support structure to rotate along the inner diameter of the air outlet 204.

[0070] Optionally, in the case where the support structure is a support frame, the bottom of the support frame can be fixedly connected to any point on the annular gear mechanism 301, and the air supplement fan 201 can be arranged on the top of the support frame. Alternatively, in the case where the support structure is a support shaft, one end of the support shaft can be fixedly connected to any point on the annular gear mechanism 301, and the air supplement fan 201 can be arranged on the other end of the support shaft. Alternatively, in the case where the support structure is a support plate, one end of the support plate can be fixedly connected to any point on the annular gear mechanism 301, and the air supplement fan 201 can be arranged on the other end of the support plate.

[0071] It can be understood that during the rotation of the air supplement fan 201 around the inner diameter of the air outlet 204, the first rotation axis and the reference horizontal plane also move up and down with the rotation of the air supplement fan 201.

[0072] The cross-flow fan 401 is arranged below the evaporator 402. The fan blade of the cross-flow fan 401 can rotate in a clockwise direction or in an anticlockwise direction.

[0073] Optionally, the air conditioner also includes a movable baffle 206. The movable baffle 206 can be extended when the air conditioner is turned on to allow air to be drawn into the air conditioner through the air inlet 205. The movable baffle 206 can also be pushed in when the air conditioner is turned off to cover the air inlet 205.

[0074] The movable baffle 206 can be driven by a second stepper motor 208 located near the air inlet 205.

[0075] It should be noted that in this embodiment of the invention, each supplementary air fan 201 can rotate synchronously around the inner diameter of each air outlet 204; each supplementary air fan 201 can also rotate independently around the inner diameter of the corresponding air outlet 204 according to a preset rule. The specific manner in which each supplementary air fan 201 rotates around each air outlet 204 is not limited in this embodiment of the invention.

[0076] It should be noted that in this embodiment of the invention, each air supply fan 201 can rotate synchronously relative to each first rotation axis; each air supply fan 201 can also rotate independently relative to its corresponding first rotation axis according to a preset rule. The specific manner in which each air supply fan 201 rotates relative to each first rotation axis is not limited in this embodiment of the invention.

[0077] Typically, users can control the air conditioner's compressor to start, its operating mode to control, or its shutdown to control its operation, according to their actual needs. User control can be based on user-inputted commands. For example, the air conditioner's controller can receive a first user-inputted command and, in response, start the compressor for cooling; or, the controller can receive a second user-inputted command and, in response, operate the air conditioner in fan mode; or, the controller can receive a third user-inputted command and, in response, shut down the air conditioner.

[0078] It should be noted that user input can take the form of touch input on the target interface, including but not limited to click, swipe, and press input. User input can also be expressed as physical button input or voice input. The target interface can be the user terminal's display interface or the air conditioner's control interface. The physical buttons can be located on the air conditioner itself or on the air conditioner's external controller.

[0079] It is understood that the inputs listed above are merely exemplary examples, meaning that the embodiments of this application include, but are not limited to, the inputs listed above. In actual implementation, user input may include any other possible inputs, which can be specifically determined according to actual usage needs, and the embodiments of this application do not impose any limitations.

[0080] In this embodiment of the invention, when the air conditioner is started, the operating mode of the air conditioner can be obtained in a variety of ways. For example, the operating mode of the air conditioner can be obtained by detecting the control commands received by the air conditioner's controller; or, the operating mode of the air conditioner can be obtained based on the working status of the air conditioner's compressor.

[0081] The operating modes of an air conditioner may include, but are not limited to: cooling mode, heating mode, fan mode, defrost mode, and self-cleaning mode. In cooling mode, the air conditioner blows out cold air to lower the indoor temperature; in heating mode, it blows out hot air to raise the indoor temperature; in fan mode, it blows out natural air to increase indoor air circulation; in defrost mode, it automatically defrosts; and in self-cleaning mode, it performs self-cleaning.

[0082] In this embodiment of the invention, when the air conditioner is turned on, the temperature difference between the indoor and outdoor environments can be obtained in various ways. For example, a temperature difference sensor can be used to obtain the indoor and outdoor temperatures respectively, and the temperature difference between the indoor and outdoor environments can be obtained through numerical calculation.

[0083] It is understandable that indoor and outdoor ambient temperatures are dynamic, and correspondingly, the temperature difference between indoor and outdoor ambient temperatures is also dynamic.

[0084] Step 102: Control the air supply device in the air conditioner based on the operating mode and temperature difference.

[0085] Specifically, after obtaining the operating mode of the air conditioner and the temperature difference between the indoor and outdoor environments, a condition judgment can be made based on the operating mode of the air conditioner and the aforementioned temperature difference. Based on the result of the condition judgment, one or more of the following can be controlled: the fan speed setting and inner diameter speed setting of the air supply fan 201, the fan blade rotation mode of the cross-flow fan 401 and the air supply fan 201, and the direction of the air blown out or drawn in by the air supply fan.

[0086] It should be noted that when the blades of the cross-flow fan 401 and the air supply fan 201 rotate clockwise, the cross-flow fan 401 and the air supply fan 201 can blow out gas; when the blades of the cross-flow fan 401 and the air supply fan 201 rotate counterclockwise, the cross-flow fan 401 and the air supply fan 201 can draw in gas.

[0087] It should be noted that the supplementary air fan 201 in this embodiment of the invention may include three fan blade speed settings: a first fan blade speed setting, a second fan blade speed setting, and a third fan blade speed setting. When the supplementary air fan 201 operates at the first, second, and third fan blade speed settings, the fan blade rotation speed decreases sequentially. In this embodiment of the invention, the airflow speed corresponding to the first fan blade speed setting can be referred to as the high-speed wind speed, the airflow speed corresponding to the second fan blade speed setting as the medium-speed wind speed, and the airflow speed corresponding to the third fan blade speed setting as the low-speed wind speed.

[0088] The air supply fan 201 in this embodiment of the invention may include three inner diameter speed settings: a first inner diameter speed setting, a second inner diameter speed setting, and a third inner diameter speed setting. When the air supply fan 201 operates at the first, second, and third inner diameter speed settings, the rotation speed around the inner diameter of the corresponding air outlet 204 decreases sequentially. In this embodiment of the invention, the speed corresponding to the first inner diameter speed setting can be referred to as the high speed setting, the speed corresponding to the second inner diameter speed setting as the medium speed setting, and the speed corresponding to the third inner diameter speed setting as the low speed setting.

[0089] This invention controls the air supply device in the air conditioner based on the air conditioner's operating mode and the temperature difference between indoor and outdoor environments. The air supply device includes a cross-flow fan and multiple supplementary air fans. The air conditioner includes multiple air outlets, and each supplementary air fan can rotate around the inner diameter of its corresponding air outlet. This increases the air outlet range and airflow distance of the air conditioner without increasing the user's feeling of being blown by the airflow. It allows for more flexible control of the air supply device in the air conditioner according to actual conditions, thereby improving the air conditioner's heat exchange efficiency and capacity, enhancing its efficiency in regulating indoor ambient temperature, improving user experience, and reducing the air conditioner's energy consumption.

[0090] Based on the above embodiments, based on the operating mode and temperature difference, the air supply device in the air conditioner is controlled, including: when the operating mode of the air conditioner is cooling mode, controlling the blades of the cross-flow fan 401 and the blades of the supplementary air fan 201 to rotate clockwise, and determining the preset range of the temperature difference.

[0091] Among them, the first preset interval, the second preset interval and the third preset interval are connected and increase sequentially; the fan blade rotation speed of the air supply fan 201 decreases sequentially when it executes the first fan blade speed setting, the second fan blade speed setting and the third fan blade speed setting; the speed at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet decreases sequentially when it executes the first inner diameter speed setting, the second inner diameter speed setting and the third inner diameter speed setting.

[0092] Specifically, when the air conditioner is in cooling mode, the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate clockwise, thereby controlling the cross-flow fan 401 and the air supply fan 201 to blow out gas.

[0093] When the air conditioner is in cooling mode, the cross-flow fan 401 can also be controlled to execute a preset speed H0.

[0094] It should be noted that the preset speed can be determined based on prior knowledge or the speed of the compressor in the air conditioner. The specific value of the preset speed is not limited in this embodiment of the invention.

[0095] Optionally, the preset speed can be between 800 and 1300 r / min, for example, the preset speed can be 800 r / min, 1000 r / min, 1100 r / min, 1200 r / min or 1300 r / min.

[0096] When the temperature difference is within the first preset range, the air supply fan 201 is controlled to execute the first blade speed setting and the first inner diameter speed setting.

[0097] Specifically, based on the preset range of the temperature difference between the outdoor and indoor environments, it can be determined whether the temperature difference is large, moderate, or small. A large temperature difference indicates that the indoor temperature has met the user's needs, and the user's temperature adjustment requirements for the air conditioner are low. A moderate temperature difference indicates that the indoor temperature is close to the user's needs, and the user's temperature adjustment requirements for the air conditioner are moderate. A small temperature difference indicates that the indoor temperature is far from meeting the user's needs, and the user's temperature adjustment requirements for the air conditioner are high. In this embodiment of the invention, ΔT can be used to represent the temperature difference between the outdoor and indoor environments.

[0098] It should be noted that the first preset interval, the second preset interval, and the third preset interval can be determined based on prior knowledge. In this embodiment of the invention, the first preset interval, the second preset interval, and the third preset interval are not specifically limited.

[0099] Optionally, the first preset interval can be [0,5], the second preset interval can be (5,15], and the third preset interval can be (15,+∞).

[0100] When ΔT∈[0,5], it indicates that the temperature difference between the outdoor and indoor environments is small. The air supply fan 201 can be controlled to execute the first blade speed setting and the first inner diameter speed setting, so that the air conditioner delivers cold air at a high speed and the indoor air flow speed is the fastest. Thus, when the temperature difference is in the first preset range, the cooling capacity of the air conditioner can be maximized, and the indoor temperature can be cooled down the fastest.

[0101] When the temperature difference is within the second preset range, the air supply fan 201 is controlled to execute the second blade speed setting and the second inner diameter speed setting.

[0102] When ΔT∈(5,15], it indicates that the temperature difference between the outdoor and indoor environments is moderate. The air supply fan 201 can be controlled to execute the second blade speed setting and the second inner diameter speed setting, so that the air conditioner delivers cold air at a medium speed and the indoor air flow speed is moderate. Thus, when the temperature difference is within the second preset range, the cooling capacity of the air conditioner can be controlled to be moderate, and the cooling rate of the indoor environment can be moderate.

[0103] When the temperature difference is within the third preset range, the supplementary air fan 201 is controlled to execute the third blade speed setting and the third inner diameter speed setting, and the angle between the direction of the air blown out by the supplementary air fan 201 and the vertical upward direction is controlled to be less than 90°.

[0104] When ΔT∈(15,+∞), it indicates that the temperature difference between the outdoor and indoor environments is large. The air supply fan 201 can be controlled to execute the third blade speed setting and the third inner diameter speed setting, so that the air conditioner delivers cold air at a low speed and the indoor air flow speed is the slowest. Thus, when the temperature difference is within the third preset range, the cooling capacity of the air conditioner can be minimized to maintain the indoor environment temperature.

[0105] It should be noted that, in this embodiment of the invention, the angle between the central axis of the projection of the supplementary air fan 201 onto the plane where the air outlet 204 is located and the central axis of the air outlet 204 in the vertically upward direction, in the clockwise direction, can be taken as the rotation angle of the supplementary air fan 201 relative to the first rotation axis. The central axis of the projection of the supplementary air fan 201 onto the plane where the air outlet 204 is located passes through the center point of the air outlet 204.

[0106] Figure 5 This is the second perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. When the rotation angle of the air supply fan 201 relative to the first rotation axis is 0° or 360°, the perspective view of the air conditioner is as follows. Figure 5 As shown.

[0107] Figure 6This is the third perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating at a 90° angle relative to the first rotation axis, the perspective view of the air conditioner is as follows. Figure 6 As shown.

[0108] Figure 7 This is the fourth perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating at an angle of 180° relative to the first rotation axis, the perspective view of the air conditioner is as follows. Figure 7 As shown.

[0109] Figure 8 This is the fifth perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating at an angle of 270° relative to the first rotation axis, the perspective view of the air conditioner is as follows. Figure 8 As shown.

[0110] like Figures 5 to 8 As shown, when the rotation angle of the supplementary air fan 201 relative to the first rotation axis is within [0°, 90°] and within [270°, 360°], the angle between the direction of the gas blown by the supplementary air fan 201 and the vertically upward direction is less than 90°, that is, the supplementary air fan 201 blows gas above the reference horizontal plane; when the rotation angle of the supplementary air fan 201 relative to the first rotation axis is within (90°, 270°), the angle between the direction of the gas blown by the supplementary air fan 201 and the vertically downward direction is less than 90°, that is, the supplementary air fan 201 blows gas below the reference horizontal plane.

[0111] When the air conditioner is in cooling mode and the temperature difference is within the third preset range, it indicates that the indoor ambient temperature has met the user's requirements. In order to avoid the cold air blown out by the air conditioner directly blowing on the user and causing poor user comfort, the rotation angle of the air supply fan 201 relative to the first rotation axis can be controlled within [0°, 90°] and within [270°, 360°]. That is, the angle between the direction of the air supply fan 201 blowing out gas and the vertical upward direction can be controlled to be less than 90°. This allows the air conditioner to blow cold air upwards towards the reference horizontal plane, avoiding the cold air blowing directly on the user. It also allows the denser cold air to flow downwards naturally, improving the cooling effect of the air conditioner.

[0112] This invention, when the air conditioner is in cooling mode, controls the blades of the cross-flow fan and the air supply fan to rotate clockwise. Based on a preset range of temperature difference between the indoor and outdoor environments, it provides more flexible control over the fan speed, inner diameter speed, and direction of the air blown out by the air supply fan. This allows for more flexible control over the airflow speed in cooling mode, improving the heat exchange efficiency and capacity of the air conditioner and reducing its energy consumption.

[0113] Based on the above embodiments, based on the operating mode and temperature difference, the air supply device in the air conditioner is controlled, including: when the operating mode of the air conditioner is heating mode, controlling the blades of the cross-flow fan 401 and the blades of the supplementary air fan 201 to rotate clockwise, and determining the preset range of the temperature difference.

[0114] Specifically, when the air conditioner is in heating mode, the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate clockwise, thereby controlling the cross-flow fan 401 and the air supply fan 201 to blow out gas.

[0115] When the air conditioner is in heating mode, the cross-flow fan 401 can also be controlled to execute a preset speed H0.

[0116] When the temperature difference is within the first preset range, the air supply fan 201 is controlled to execute the first blade speed setting and the first inner diameter speed setting.

[0117] Specifically, when ΔT∈[0,5], it indicates that the temperature difference between the outdoor and indoor environments is small. The air supply fan 201 can be controlled to execute the first blade speed setting and the first inner diameter speed setting, so that the air conditioner delivers hot air at a high speed and the indoor air flow speed is the fastest. Thus, when the temperature difference is in the first preset range, the heating capacity of the air conditioner can be maximized, and the indoor temperature can be raised the fastest.

[0118] When the temperature difference is within the second preset range, the air supply fan 201 is controlled to execute the second blade speed setting and the second inner diameter speed setting.

[0119] Specifically, when ΔT∈(5,15], it indicates that the temperature difference between the outdoor and indoor environments is moderate. The air supply fan 201 can be controlled to execute the second blade speed setting and the second inner diameter speed setting, so that the air conditioner delivers hot air at a medium speed and the indoor air flow speed is moderate. Thus, when the temperature difference is in the second preset range, the heating capacity of the air conditioner can be controlled to be moderate, and the indoor temperature rise rate can be moderate.

[0120] When the temperature difference is within the third preset range, the supplementary air fan 201 is controlled to execute the third blade speed setting and the third inner diameter speed setting, and the angle between the direction of the air blown out by the supplementary air fan 201 and the vertical downward direction is controlled to be less than 90°.

[0121] Specifically, when ΔT∈(15,+∞), it indicates that the temperature difference between the outdoor and indoor environments is large. The air supply fan 201 can be controlled to execute the third blade speed setting and the third inner diameter speed setting, so that the air conditioner delivers hot air at a low speed and the indoor air flow speed is the slowest. Thus, when the temperature difference is within the third preset range, the heating capacity of the air conditioner can be minimized, thereby maintaining the indoor ambient temperature.

[0122] It should be noted that the temperature of the hot air blown out by the air conditioner in heating mode decreases continuously with the increase of the airflow distance. This means that when the airflow distance is relatively far, the user may feel that the air conditioner is blowing cool air, resulting in a poor user comfort experience. When the air conditioner is in heating mode and the aforementioned temperature difference is within the third preset range, it indicates that the indoor ambient temperature has reached the user's desired temperature. In this case, to prevent the user from feeling that the air conditioner is blowing cool air, the rotation angle of the air supply fan 201 relative to the first rotation axis can be controlled within (90°, 270°). That is, the angle between the direction of the air supply fan 201 blowing air and the vertical downward direction can be controlled to be less than 90°. This allows the air conditioner to blow hot air downwards towards the reference horizontal plane, preventing the user from feeling that the air conditioner is blowing cool air. It also allows the less dense hot air to naturally rise, improving the heating effect of the air conditioner.

[0123] This invention, when the air conditioner is in heating mode, controls the blades of the cross-flow fan and the air supply fan to rotate clockwise. Based on a preset range of temperature difference between the indoor and outdoor environments, it provides more flexible control over the fan speed, inner diameter speed, and direction of the air blown out by the air supply fan. This allows for more flexible control over the airflow speed in cooling mode, improving the heat exchange efficiency and capacity of the air conditioner and reducing its energy consumption.

[0124] Based on the above embodiments, based on the operating mode and temperature difference, the air supply device in the air conditioner is controlled, including: when the air conditioner is in the air supply mode, controlling the blades of the cross-flow fan 401 and the blades of the supplementary air fan 201 to rotate clockwise, controlling the angle between the direction of the air blown out by the supplementary air fan 201 and the vertical downward direction to be less than 90°, and determining the preset range of the temperature difference.

[0125] Specifically, when the air conditioner is in the air supply mode, the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate clockwise, thereby controlling the cross-flow fan 401 and the air supply fan 201 to blow out air.

[0126] When the air conditioner is in the air supply mode, the cross-flow fan 401 can also be controlled to execute the preset speed H0.

[0127] To improve the long-distance air delivery capability of the air conditioner in air supply mode, when the air conditioner is in cooling mode, the rotation angle of the air supply fan 201 relative to the first rotation axis can be controlled within (90°, 270°). That is, the angle between the direction of the air blown out by the air supply fan 201 and the vertical downward direction can be controlled to be less than 90°. This allows the air conditioner to deliver air downward to the reference horizontal plane in air supply mode, which can increase the air blowing distance of the air conditioner in air supply mode, thereby further increasing the air circulation in the room.

[0128] When the temperature difference is within the first preset range, the air supply fan 201 is controlled to execute the second blade speed setting and the second inner diameter speed setting.

[0129] Specifically, when ΔT∈[0,5], it indicates that the temperature difference between the outdoor and indoor environments is small, and the air supply fan 201 can be controlled to execute the second blade speed setting and the second inner diameter speed setting, so that the air conditioner delivers air at a medium speed to the lower part of the reference horizontal plane, and the indoor air flow speed is moderate.

[0130] When the temperature difference is in the second or third preset range, control the speed of the first blade and the speed of the second inner diameter of the air supply fan 201.

[0131] Specifically, when ΔT∈(5,+∞), it indicates that the temperature difference between the outdoor and indoor environments is moderate or large, and the air supply fan 201 can be controlled to execute the first blade speed setting and the second inner diameter speed setting, so that the air conditioner delivers air at a high speed to the area below the reference horizontal plane, and the indoor air flow speed is moderate.

[0132] This invention, when the air conditioner is in ventilation mode, controls the blades of the cross-flow fan and the air supply fan to rotate clockwise, ensuring the angle between the direction of the air blown out by the air supply fan and the vertical downward direction is less than 90°. Based on a preset range of temperature difference between indoor and outdoor environments, the invention provides more flexible control over the fan blade speed and inner diameter speed. This allows for more flexible control of the airflow speed in ventilation mode, increasing the airflow distance and further enhancing indoor air circulation, thereby reducing the air conditioner's energy consumption.

[0133] Based on the above embodiments, based on the operating mode and temperature difference, the air supply device in the air conditioner is controlled to rotate clockwise around the inner diameter of the corresponding air outlet 204 when the operating mode of the air conditioner is cooling mode or heating mode and the temperature difference is within the fourth preset range.

[0134] It should be noted that the fourth preset interval can be determined based on prior knowledge. In this embodiment of the invention, the fourth preset interval is not specifically limited.

[0135] Optionally, the fourth preset interval can be (10, +∞).

[0136] Specifically, when the air conditioner is in cooling or heating mode and ΔT∈(10,+∞), it indicates that the indoor ambient temperature has not yet met the user's needs. In order to improve the temperature regulation effect of the air conditioner, the air supply fan 201 can be controlled to rotate clockwise around the inner diameter of the corresponding air outlet 204.

[0137] This invention, when the air conditioner is in cooling or heating mode and the temperature difference between the indoor and outdoor environments is within a fourth preset range, controls the air supply fan to rotate clockwise around the inner diameter of the corresponding air outlet. This allows for more flexible control of the air supply fan's rotation around the inner diameter of the corresponding air outlet, thereby improving the air conditioner's heat exchange efficiency and capacity, and reducing its energy consumption.

[0138] Based on the above embodiments, and based on the operating mode and temperature difference, the air supply device in the air conditioner is controlled, including: when the operating mode of the air conditioner is the target mode, controlling the blades of the cross-flow fan 401 and the blades of the supplementary air fan 201 to rotate counterclockwise, controlling the angle between the direction of the supplementary air fan 201 drawing in gas and the vertical upward direction to be less than 90°, and controlling the supplementary air fan 201 to execute the second blade speed setting.

[0139] The target modes include: defrosting mode or self-cleaning mode.

[0140] Specifically, in order not to affect the performance of the air conditioner in the target mode and to reduce the noise of the air conditioner, when the air conditioner is in the target mode and the temperature difference is arbitrary, the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate counterclockwise. This allows the cross-flow fan 401 and the air supply fan 201 to draw in air. The air supply fan 201 can also be controlled to execute the second blade speed setting, so that the air conditioner can draw in air from above the reference horizontal plane at a medium fan speed.

[0141] It should be noted that, in order to avoid affecting the performance of the air conditioner, in this embodiment of the invention, when the air conditioner is in the target mode, the rotation angle of the air supply fan 201 relative to the first rotation axis can be controlled within [0°, 90°] and within [270°, 360°]. That is, the angle between the direction of the air supply fan 201 drawing in the gas and the vertical upward direction is controlled to be less than 90°, so that the air conditioner can draw in gas from above the reference horizontal plane in the target mode.

[0142] It should be noted that when the air conditioner is in target mode, the speed at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet 204 is zero.

[0143] In this embodiment of the invention, when the air conditioner is in the target operating mode, the blades of the cross-flow fan and the air supply fan are controlled to rotate counterclockwise, the angle between the direction of the air supply fan drawing in the gas and the vertical upward direction is controlled to be less than 90°, and the speed of the air supply fan blades is controlled to execute the third target speed. This can control the air conditioner to draw in gas from above the horizontal plane, avoid affecting the performance of the air conditioner in the target mode, and reduce the noise of the air conditioner.

[0144] Based on the above embodiments, the rotation of each supplementary air fan 201 around the inner diameter of each air outlet 204 is synchronized.

[0145] In this embodiment of the invention, each supplementary air fan rotates synchronously around the inner diameter of each air outlet, which can avoid the air supply area of ​​the air conditioner being dispersed or concentrated. Without increasing the feeling of being blown by the air, it can further increase the air outlet range and the air blowing distance of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the user experience.
