Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a control method, device and air conditioner for an air conditioner. Background Technology

[0002] In modern life, air conditioners are an essential piece of equipment in indoor spaces. By controlling the indoor ambient temperature, air conditioners can provide users with a comfortable living or working environment.

[0003] Typically, air conditioners operate in the following modes: cooling mode, heating mode, fan mode, defrost mode, and self-cleaning mode. The airflow distance of an air conditioner refers to the farthest distance that the cool air, hot air, or natural wind it blows out can reach during operation.

[0004] In existing technologies, air conditioners typically rely on built-in centrifugal or cross-flow fans for airflow. Centrifugal fans have higher air pressure, allowing for a longer airflow distance, but resulting in a stronger draft and less comfortable user experience. Cross-flow fans, on the other hand, have lower air pressure, providing a weaker draft, but with a shorter airflow distance. Furthermore, traditional air conditioners usually deliver air at a fixed speed, which is insufficient for optimal temperature control in real-world scenarios, leading to low efficiency in regulating indoor temperature. Therefore, achieving a longer airflow distance with a weaker draft, while simultaneously providing more efficient indoor temperature control, is a pressing technical challenge in this field. Summary of the Invention

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0054] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] Figure 1 This is a flowchart illustrating the control method for an air conditioner provided by the present invention. The following is a summary of the process. Figure 1 The control method of the air conditioner of the present invention is described. For example... Figure 1 As shown, the method includes: step 101, when the air conditioner is started, obtaining the operating mode of the air conditioner and the frequency of the compressor in the air conditioner.

[0056] It should be noted that the execution subject of this embodiment of the invention is the control device of an air conditioner.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] In this embodiment of the invention, when the air conditioner is started, the operating mode and the frequency of the compressor in 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; the frequency of the compressor can also be obtained by using the air conditioner's controller.

[0061] 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.

[0062] It is understandable that the frequency of the compressor in an air conditioner can change dynamically over time.

[0063] Step 102: Control the air supply device in the air conditioner based on the operating mode and frequency.

[0064] The air conditioner includes a first number of air outlets; the air supply device includes a cross-flow fan and a first number of supplementary air fans; the first number is not less than 2; the supplementary air fans and the air outlets have a one-to-one correspondence; the supplementary air fans can rotate around the inner diameter of the air outlets.

[0065] It should be noted that, because cross-flow fans have the characteristics of long airflow distance but small airflow range, resulting in a weaker airflow sensation for users, the air supply device in the air conditioner of this embodiment includes a cross-flow fan and multiple rotatable supplementary air fans. Compared to air conditioners using centrifugal fans, cross-flow fans can increase the airflow distance of the air conditioner. At the same time, by utilizing multiple rotatable supplementary air fans, the airflow range of the air conditioner can be increased. Thus, it is possible to increase the airflow range and airflow distance of the air conditioner without increasing the user's airflow sensation.

[0066] Figure 2 This is one of the perspective views of the air conditioner in the air conditioner control method provided by the present invention. Figure 3 This is a front view of the air conditioner in the air conditioner control method provided by the present invention. Figure 4 This is a cross-sectional view of the air conditioner in the air conditioner control method provided by the present invention. Figure 2 , Figure 3 and Figure 4 As shown, the air supply device in the air conditioner includes a cross-flow fan 401 and a first number of supplementary air fans 201.

[0067] The surface of the air conditioner housing 203 is provided with a first number of air outlets 204. The first number is not less than 2; in this embodiment of the invention, a value of 2 is used as an example for explanation.

[0068] Each air outlet 204 is provided with an air supply fan 201, which can rotate clockwise or counterclockwise around the inner diameter of the air outlet 204.

[0069] It should be noted that the structures of each air outlet 204 are identical. In this embodiment of the invention, an air outlet 204 and the air supply fan 201 disposed at the air outlet 204 are used as examples to describe the air conditioner and the control method of the air conditioner provided by the present invention. The air outlet 204 and the air supply fan 201 mentioned in the following description can refer to any air outlet 204 in the air conditioner and the air supply fan 201 disposed at the air outlet 204.

[0070] The supplementary air fan 201 is rotatably connected to the support structure. In this embodiment of the invention, the central axis of the support structure perpendicular to the plane where the air outlet 204 is located can be used as the first axis of rotation, and the horizontal plane where the first axis of rotation is located can be used as the reference horizontal plane. The supplementary air fan 201 can rotate relative to the first axis of rotation. By controlling the rotation angle of the supplementary air fan 201 relative to the first axis of rotation, the direction of the air blown out or drawn in by the supplementary air fan 201 can be controlled.

[0071] Optionally, the aforementioned support structure can be a support frame, a support shaft, or a support plate. The embodiments of the present invention do not limit the specific structure of the aforementioned support structure.

[0072] Optionally, the supplementary air fan 201 may include an integrated filter, fan blades, and a rotary motor. The rotary motor can drive the fan blades to rotate clockwise or counterclockwise. The filter is located on the outer side of the fan blades and can be used to filter the air blown out or drawn in by the supplementary air fan 201. The outer side of the fan blades refers to the side closest to the indoor space.

[0073] Optionally, a ring gear mechanism 301 can be provided within the housing 203 along the inner diameter of the air outlet 204. The diameter of the ring gear mechanism 301 is slightly larger than the diameter of the air outlet 204, and the difference between the diameter of the ring gear mechanism 301 and the diameter of the air outlet 204 is less than a preset value. This difference ensures that the diameter of the ring gear mechanism 301 is not excessively large. The preset value can be determined based on prior knowledge, and the specific value of the preset value is not limited in this embodiment of the invention.

[0074] Accordingly, the supplementary air fan 201 can be fixedly connected to any point on the ring gear mechanism 301 through the support structure, and the ring gear mechanism 301 can be driven to rotate by the first stepper motor 207. In turn, the ring gear mechanism 301 can drive the supplementary air fan 201 connected to the support structure to rotate along the inner diameter of the air outlet 204.

[0075] Optionally, when the support structure is a support frame, the bottom of the support frame can be fixedly connected to any point on the ring gear mechanism 301, and the top of the support frame can be equipped with an air supply fan 201; or, when the support structure is a support shaft, one end of the support shaft can be fixedly connected to any point on the ring gear mechanism 301, and the other end of the support shaft can be equipped with an air supply fan 201; or, when the support structure is a support plate, one end of the support plate can be fixedly connected to any point on the ring gear mechanism 301, and the other end of the support plate can be equipped with an air supply fan 201.

[0076] It is understandable that as the air supply fan 201 rotates along 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 supply fan 201.

[0077] A cross-flow fan 401 is located below the evaporator 402. The blades of the cross-flow fan 401 can rotate clockwise or counterclockwise.

[0078] 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.

[0079] The movable baffle 206 can be driven by a second stepper motor 208 located near the air inlet 205.

[0080] 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.

[0081] 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.

[0082] This invention controls the air supply device in the air conditioner based on the air conditioner's operating mode and the frequency of the compressor. The air supply device includes a cross-flow fan and multiple supplementary air fans. The air conditioner includes multiple air outlets, and the supplementary air fans can rotate around the inner diameter of the corresponding air outlets. This increases the air outlet range and airflow distance of the air conditioner without increasing the user's feeling of being blown by the air, thereby improving the heat exchange efficiency of the air conditioner, improving the air conditioner's efficiency in regulating indoor temperature, and enhancing the user's perception.

[0083] Based on the above embodiments, the air supply device in the air conditioner is controlled based on the operating mode and frequency, including: when the air conditioner is in cooling mode, determining a first target speed and a second target speed based on the frequency.

[0084] Specifically, after obtaining the operating mode of the air conditioner, if the operating mode of the air conditioner is cooling mode, the first target speed H1 and the second target speed H2 can be determined by numerical calculation based on the frequency H of the compressor in the air conditioner.

[0085] Optionally, the first target speed H1 can be the product of the compressor frequency H and the first preset value x1, i.e., H1 = H × x1. The first preset value x1 can be between 5 and 7, for example, the first preset value x1 can be 5, 6 or 7.

[0086] Preferably, the first preset value x1 can be 6, that is, H1 = H × 6.

[0087] Alternatively, the compressor frequency H can be used as the second target speed H2, i.e., H2 = H.

[0088] The blades of the cross-flow fan 401 and the air supply fan 201 are controlled to rotate clockwise. The angle between the direction of the air blown out by the air supply fan 201 and the vertical upward direction is controlled to be less than 90°. The speed of the air supply fan 201 blades is controlled to achieve the first target speed. The speed of the air supply fan 201 rotating around the inner diameter of the corresponding air outlet 204 is controlled to achieve the second target speed.

[0089] Specifically, in order to improve the air delivery effect of the air conditioner in cooling mode and reduce the noise of the air conditioner, 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. The speed of the blades of the cross-flow fan 401 is controlled to execute a first preset speed, the speed of the blades of the air supply fan 201 is controlled to execute a first target speed H1, and the speed of the air supply fan 201 rotating around the inner diameter of the corresponding air outlet 204 is controlled to execute a second target speed H2. This allows the air supply effect of the air conditioner to be improved when the compressor frequency is increased.

[0090] It should be noted that the first preset rotational speed can be predetermined based on prior knowledge or set by the user. The specific value of the first preset rotational speed is not limited in this embodiment of the invention.

[0091] 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.

[0092] In this embodiment of the invention, when the supplementary air fan 210 blows out gas, the angle between the projection of the direction of the gas blown out by the supplementary air fan 201 onto the plane where the air outlet 204 is located and the clockwise direction of the vertical upward direction in the plane where the air outlet 204 is located can be used as the blowing angle of the supplementary air fan 201; when the supplementary air fan 210 draws in gas, the angle between the projection of the direction of the gas drawn in by the supplementary air fan 201 onto the plane where the air outlet 204 is located and the clockwise direction of the vertical upward direction in the plane where the air outlet 204 is located can be used as the angle of the gas drawn in by the supplementary air fan 201.

[0093] 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° (360°), or when the blowing angle of the air supply fan 201 is 0° (360°), the perspective view of the air conditioner is as follows. Figure 5 As shown.

[0094] Figure 6 This is the third 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 90°, or when the blowing angle of the air supply fan 201 is 90°, the perspective view of the air conditioner is as follows. Figure 6 As shown.

[0095] 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. When the rotation angle of the air supply fan 201 relative to the first rotation axis is 180°, or when the blowing angle of the air supply fan 201 is 180°, the perspective view of the air conditioner is as follows. Figure 7 As shown.

[0096] 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. When the rotation angle of the air supply fan 201 relative to the first rotation axis is 270°, or when the blowing angle of the air supply fan 201 is 270°, the perspective view of the air conditioner is as follows. Figure 8 As shown.

[0097] 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.

[0098] To prevent the cold air blown directly onto users during cooling mode, thus improving user comfort, the rotation angle of the air supply fan 201 relative to the first rotation axis can be controlled within [0°, 90°] and [270°, 360°] when the air conditioner is in cooling mode. This means the angle between the direction of the air supply fan 201 blowing air and the vertically upward direction is less than 90°. This allows the air conditioner to blow cold air upwards towards the reference horizontal plane during cooling mode, preventing direct airflow onto users and allowing denser cold air to naturally flow downwards, thus improving the air conditioner's cooling effect.

[0099] Accordingly, when the air conditioner is in cooling mode, the blowing angle of the air supply fan 201 is between 0° and 90° and between 270° and 360°.

[0100] This invention, when the air conditioner is in cooling mode, determines a first target speed and a second target speed based on the compressor frequency, and controls the blades of the cross-flow fan and the supplementary air fan to rotate clockwise. The angle between the direction of the air blown out by the supplementary air fan and the vertically upward direction is controlled to be less than 90°. The blade speed of the supplementary air fan is controlled to achieve the first target speed, and the rotation speed of the supplementary air fan 201 around the inner diameter of the corresponding air outlet is controlled to achieve the second target speed. This improves the air delivery effect of the air conditioner in cooling mode by increasing the compressor frequency, reduces air conditioner noise, and prevents the air conditioner from blowing cold air directly onto the user by controlling the air conditioner to blow cold air upwards in cooling mode. It also allows denser cold air to flow naturally downwards, thereby improving the cooling effect and enhancing the user experience.

[0101] Based on the above embodiments, the air supply device in the air conditioner is controlled based on the operating mode and frequency, including: when the air conditioner is in heating mode, determining a third target speed and a fourth target speed based on the frequency.

[0102] Specifically, after obtaining the operating mode of the air conditioner, if the operating mode of the air conditioner is heating mode, the third target speed H3 and the fourth target speed H4 can be determined by numerical calculation based on the frequency H of the compressor in the air conditioner.

[0103] Optionally, the third target speed H3 can be the product of the compressor frequency H and the second preset value x2, i.e., H3 = H × x2. The second preset value x2 can be between 4 and 6, for example, the second preset value x2 can be 4, 5 or 6.

[0104] Preferably, the second preset value x2 can be 5, i.e., H3 = H × 5.

[0105] Alternatively, the compressor frequency H can be used as the fourth target speed H4, i.e., H4 = H.

[0106] It should be noted that the fourth target speed H4 and the second target speed H2 can be the same or different.

[0107] Control the blades of the cross-flow fan 401 and the air supply fan 201 to rotate clockwise, control the angle between the direction of the air blown out by the air supply fan 201 and the vertical downward direction to be less than 90°, control the speed of the air supply fan 201 to execute the third target speed, and control the speed of the air supply fan 201 to rotate around the inner diameter of the corresponding air outlet to execute the fourth target speed.

[0108] The third target rotational speed is less than the first target rotational speed.

[0109] Specifically, in order to improve the air delivery effect of the air conditioner in heating mode and reduce the noise of the air conditioner, 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. The blade speed of the cross-flow fan 401 is controlled to execute the second preset speed, the blade speed of the air supply fan 201 is controlled to execute the third target speed H3, and the rotation speed of the air supply fan 201 around the inner diameter of the corresponding air outlet 204 is controlled to execute the fourth target speed H4. In this way, the higher the frequency of the compressor, the faster the blade speed of the air supply fan 201 and the faster the rotation speed of the air supply fan 201 around the inner diameter of the corresponding air outlet 204, so as to improve the heat exchange effect of the air conditioner when the compressor frequency is increased.

[0110] It should be noted that the second preset rotational speed is predetermined based on prior knowledge. The specific value of the second preset rotational speed is not limited in this embodiment of the invention. The second preset rotational speed may be the same as or different from the first preset rotational speed.

[0111] 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 blowing distance. This results in users feeling that the air conditioner is blowing cool air when the blowing distance is relatively far, leading to a poor user comfort experience. Therefore, in this embodiment of the invention, when the air conditioner is in heating mode, the rotation angle of the supplementary air fan 201 relative to the first rotation axis can be controlled within (90°, 270°). Specifically, the angle between the direction of the air blown out by the supplementary air fan 201 and the vertically downward direction can be controlled to be less than 90°, and the third target speed H3 is less than the first target speed H1. This allows the air conditioner to blow hot air downwards towards the reference horizontal plane in heating mode. By controlling the fan blade speed of the supplementary air fan 201 to achieve the third target speed H3 (the third target speed H3 is less than the first target speed H1), the blowing distance of the air conditioner is shortened. This avoids users feeling that the air conditioner is blowing cool air and also allows the less dense hot air to naturally flow upwards, improving the heating effect of the air conditioner.

[0112] like Figures 5 to 8 As shown, when the air conditioner is in heating mode, the blowing angle of the air supply fan 201 is between 90° and 270°.

[0113] This invention, when the air conditioner is in heating mode, determines a third and fourth target speed based on the compressor frequency, and controls the blades of the cross-flow fan and the supplementary air fan to rotate clockwise. The angle between the direction of the air blown out by the supplementary air fan and the vertically downward direction is controlled to be less than 90°. The speed of the supplementary air fan blades is controlled to achieve the third target speed, and the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet is controlled to achieve the fourth target speed. The third target speed is less than the first target speed. This improves the air delivery effect of the air conditioner in heating mode while increasing the compressor frequency, reduces the noise of the air conditioner, and prevents users from feeling that the air conditioner is blowing cool air by controlling the downward blowing of hot air and shortening the blowing distance in heating mode. It also allows the less dense hot air to naturally flow upward, thereby improving the heating effect of the air conditioner and enhancing user perception.

[0114] Based on the above embodiments, the air supply device in the air conditioner is controlled based on the operating mode and frequency, including: when the air conditioner is in the air supply mode, determining the fifth target speed and the sixth target speed based on the frequency.

[0115] Specifically, after obtaining the operating mode of the air conditioner, if the operating mode of the air conditioner is the air supply mode, the fifth target speed H5 and the sixth target speed H6 can be determined by numerical calculation based on the frequency H of the compressor in the air conditioner.

[0116] Optionally, the fifth target speed H5 can be the product of the compressor frequency H and the third preset value x3, i.e., H5 = H × x3. The value of the third preset value x3 can be between 6 and 8, for example, the third preset value x3 can be 6, 7 or 8.

[0117] Preferably, the third preset value x3 can be 7, that is, H5 = H × 7.

[0118] Alternatively, the compressor frequency H can be used as the sixth target speed H6, i.e., H6 = H.

[0119] Control the blades of the cross-flow fan 401 and the air supply fan 201 to rotate clockwise, control the angle between the direction of the air blown out by the air supply fan 201 and the vertical upward and downward direction to be less than 90°, control the speed of the air supply fan 201 to execute the fifth target speed, and control the speed of the air supply fan 201 to rotate around the inner diameter of the corresponding air outlet 204 to execute the sixth target speed.

[0120] The fifth target rotational speed is greater than the first target rotational speed.

[0121] Specifically, in order to improve the air supply effect of the air conditioner in the air supply mode and reduce the noise of the air conditioner, 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. The speed of the blades of the cross-flow fan 401 is controlled to the third preset speed, the speed of the blades of the air supply fan 201 is controlled to the fifth target speed H5, and the speed of the air supply fan 201 rotating around the inner diameter of the corresponding air outlet 204 is controlled to the sixth target speed H6. In this way, the higher the frequency of the compressor, the faster the speed of the blades of the air supply fan 201 and the faster the speed of the air supply fan 201 rotating around the inner diameter of the corresponding air outlet 204, so as to improve the air supply effect of the air conditioner when the frequency of the compressor is increased.

[0122] It should be noted that the third preset rotational speed is predetermined based on prior knowledge. The specific value of the third preset rotational speed is not limited in the embodiments of the present invention. The third preset rotational speed may be the same as or different from the second preset rotational speed and / or the first preset rotational speed.

[0123] It should be noted that, in order to improve the long-distance air delivery capability of the air conditioner in the air delivery mode, in this embodiment of the invention, when the air conditioner is in the air delivery mode, the rotation angle of the supplementary air 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 supplementary air fan 201 and the vertical downward direction is controlled to be less than 90°, and the fifth target speed H5 is greater than the first target speed H1. This allows the air conditioner to blow natural wind downwards from the reference horizontal plane in the air delivery mode, and by controlling the fan blade speed of the supplementary air fan 201 to execute the fifth target speed H5 (the fifth target speed H5 is greater than the first target speed H1), the air delivery distance of the air conditioner is increased.

[0124] like Figures 5 to 8 As shown, when the air conditioner is in the air supply mode, the blowing angle of the air supply fan 201 is between 90° and 270°.

[0125] This invention, when the air conditioner is in ventilation mode, determines a fifth and sixth target speed based on the compressor frequency, and controls the blades of the cross-flow fan and the supplementary air fan to rotate clockwise. The angle between the direction of the air blown out by the supplementary air fan and the vertically downward direction is controlled to be less than 90°. The blade speed of the supplementary air fan is controlled to achieve the fifth target speed, and the rotation speed of the supplementary air fan 201 around the inner diameter of the corresponding air outlet is controlled to achieve the sixth target speed. The fifth target speed is greater than the first target speed. This improves the air delivery effect of the air conditioner in ventilation mode by increasing the compressor frequency, reduces the noise of the air conditioner, and further increases indoor air circulation by controlling the air conditioner to blow natural air downwards and increasing the air blowing distance in ventilation mode, thus improving user experience.

[0126] Based on the above embodiments, the air supply device in the air conditioner is controlled based on the operating mode and frequency, including: when the operating mode of the air conditioner is the target mode, determining the seventh target speed and the eighth target speed based on the frequency; wherein, the target mode includes: defrosting mode or self-cleaning mode.

[0127] Specifically, after obtaining the operating mode of the air conditioner, if the operating mode of the air conditioner is defrosting mode or self-cleaning mode, the seventh target speed H7 and the eighth target speed H8 can be determined by numerical calculation based on the frequency H of the compressor in the air conditioner.

[0128] Optionally, the seventh target speed H7 can be the product of the compressor frequency H and the fourth preset value x4, i.e., H7 = H × x4. The value of the fourth preset value x4 can be between 4 and 6, for example, the fourth preset value x4 can be 4, 5 or 6.

[0129] Preferably, the fourth preset value x4 can be 5, i.e., H7 = H × 5.

[0130] Alternatively, the compressor frequency H can be used as the eighth target speed H8, i.e., H8 = H.

[0131] Control the blades of the cross-flow fan 401 and the air supply fan 201 to rotate counterclockwise, control the angle between the direction of the air intake of the air supply fan 201 and the vertical upward direction to be less than 90°, control the speed of the air supply fan 201 to execute the seventh target speed, and control the speed of the air supply fan 201 to rotate around the inner diameter of the corresponding air outlet 204 to execute the eighth target speed.

[0132] 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, the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate counterclockwise. The speed of the blades of the cross-flow fan 401 is controlled to the fourth preset speed, the speed of the blades of the air supply fan 201 is controlled to the seventh target speed H7, and the speed of the air supply fan 201 rotating around the inner diameter of the corresponding air outlet 204 is controlled to the eighth target speed H8. This allows the higher the frequency of the compressor, the faster the speed of the blades of the air supply fan 201 and the faster the speed of the air supply fan 201 rotating around the inner diameter of the corresponding air outlet 204. Thus, the defrosting or self-cleaning effect of the air conditioner can be improved when the compressor frequency is increased.

[0133] It should be noted that the fourth preset speed is predetermined based on prior knowledge. The specific value of the fourth preset speed is not limited in the embodiments of the present invention. The third preset speed can be the same as at least one of the first, second, and third preset speeds. Alternatively, the third preset speed can be different from all three preset speeds.

[0134] 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 cross-flow fan 401 and the air supply fan 201 inhaling the gas and the vertical upward direction is controlled to be less than 90°, so that the air conditioner can inhale gas from above the reference horizontal plane in the target mode.

[0135] like Figures 5 to 8 As shown, when the air conditioner is in target mode, the angle at which the supplementary air fan 201 draws in air is between 0° and 90° and between 270° and 360°.

[0136] This invention, when the air conditioner is in target mode, determines a seventh and eighth target speed based on the compressor frequency, and controls the blades of the cross-flow fan and the supplementary air fan to rotate counterclockwise. It also controls the angle between the direction of the supplementary air fan's intake gas and the vertically upward direction to be less than 90°, controls the speed of the supplementary air fan blades to achieve the seventh target speed, and controls the speed of the supplementary air fan rotating around the inner diameter of the corresponding air outlet to achieve the eighth target speed. This allows for control of the amount of gas the air conditioner draws in during target mode based on the compressor frequency. Furthermore, by controlling the air conditioner to draw in gas from above a reference horizontal plane, it avoids affecting the air conditioner's performance during target mode and reduces air conditioner noise.

[0137] Based on the above embodiments, the rotation of each supplementary air fan 201 around the inner diameter of each air outlet 204 is synchronized.

[0138] In this embodiment of the invention, the air supply fans rotate synchronously, which can further increase the air outlet range and air blowing distance of the air conditioner without increasing the feeling of air blowing on the human body, thereby improving the heat exchange efficiency of the air conditioner and enhancing the user experience.
