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.

[0054] 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.

[0055] 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.

[0056] It should be noted that the air conditioner control method provided by the present invention is applied to an air conditioner having an air supply device and multiple air outlets; the air supply device includes: a cross-flow fan and multiple air supply fans; the air supply fans have a one-to-one correspondence with the air outlets; the air supply fans can rotate around the inner diameter of the corresponding air outlets.

[0057] 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, the frequency of the compressor in the air conditioner, and the fan speed setting of the cross-flow fan.

[0058] It should be noted that the execution subject of this embodiment of the invention is the control device of an air conditioner.

[0059] 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, control the air conditioner to operate in fan-only mode; or, the controller can receive a third user-inputted command and, in response, control the cross-flow fan to operate at a first fan speed setting.

[0060] 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.

[0061] 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.

[0062] In this embodiment of the invention, when the air conditioner is started, the operating mode of the air conditioner, the frequency of the compressor in the air conditioner, and the fan speed of the cross-flow fan 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 controller of the air conditioner; the frequency of the compressor and the fan speed of the cross-flow fan can also be obtained by using the controller of the air conditioner.

[0063] 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.

[0064] It is understandable that the frequency of the compressor in an air conditioner can change dynamically over time.

[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. (See diagram below.) 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 corresponding 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 each air supply fan 201 in the embodiments of the present invention can rotate synchronously relative to each first rotation axis; each air supply fan 201 can also rotate independently around the 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 the embodiments of the present invention.

[0082] It should be noted that the cross-flow fan 401 in this embodiment of the invention includes multiple wind speed settings, and the wind speed blown by the cross-flow fan 401 is different when different wind speed settings are executed. The supplementary air fan 201 in this embodiment of the invention also includes multiple wind speed settings, and the wind speed blown by the supplementary air fan 201 is different when different wind speed settings are executed.

[0083] It should be noted that the fan speed setting of the cross-flow fan 401 in this embodiment of the invention can be set by the user.

[0084] Step 102: Based on the wind speed setting of the cross-flow fan 401, control the wind speed setting of the supplementary air fan 201. Based on the operating mode and frequency, control the rotation direction of the blades of the cross-flow fan 401, the rotation direction of the blades of the supplementary air fan 201, the direction of the air blown out or drawn in by the supplementary air fan 201, and the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204.

[0085] Specifically, conditional judgments can be made based on the fan speed setting of the cross-flow fan, and the fan speed setting of the supplementary air fan 201 can be controlled based on the conditional judgment results; conditional judgments can be made based on the air conditioner's operating mode and the compressor's frequency, and the rotation direction of the cross-flow fan 401 blades, the rotation direction of the supplementary air fan 201 blades, the direction of the air blown out or drawn in by the supplementary air fan 201, and the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can be controlled based on the conditional judgment results.

[0086] This invention controls the air supply device in an air conditioner based on the air conditioner's operating mode, the frequency of the compressor, and the fan speed setting of the cross-flow fan. 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, enhancing the air conditioner's efficiency in regulating indoor temperature, and improving the user's perception.

[0087] Based on the above embodiments, the air supply fan 201 is controlled according to the air speed setting of the cross-flow fan 401, including: when the air speed setting of the cross-flow fan 401 is the fifth air speed setting, controlling the air supply fan 201 to execute the eighth air speed setting; when the air speed setting of the cross-flow fan 401 is the fourth air speed setting or the third air speed setting, controlling the air supply fan 201 to execute the seventh air speed setting; when the air speed setting of the cross-flow fan 401 is the second air speed setting or the first air speed setting, controlling the air supply fan 201 to execute the sixth air speed setting.

[0088] Among them, the cross-flow fan 401 increases the wind speed sequentially when it operates at the first, second, third, fourth and fifth wind speed levels; the air supply fan 201 increases the wind speed sequentially when it operates at the sixth, seventh and eighth wind speed levels.

[0089] Specifically, the cross-flow fan 401 may include five fan speed settings: powerful (fifth fan speed setting), high (fourth fan speed setting), medium (third fan speed setting), low (second fan speed setting), and silent (first fan speed setting). When the cross-flow fan 401 operates in silent (first fan speed setting), low (second fan speed setting), medium (third fan speed setting), high (fourth fan speed setting), and powerful (fifth fan speed setting), the airflow speed of the cross-flow fan 401 increases sequentially.

[0090] The air supply fan 201 can include three fan speed settings: high (eighth fan speed setting), medium (seventh fan speed setting), and low (sixth fan speed setting). When the air supply fan 201 operates at low (sixth fan speed setting), medium (seventh fan speed setting), and high (eighth fan speed setting), the air speed blown by the air supply fan 201 increases sequentially.

[0091] In this embodiment of the invention, when the cross-flow fan 401 is set to the high speed setting (fifth speed setting), the supplementary air fan 201 can be controlled to operate at a high speed setting (eighth speed setting); when the cross-flow fan 401 is set to the high speed setting or the medium speed setting (fourth or third speed setting), the supplementary air fan 201 can be controlled to operate at a medium speed setting (seventh speed setting); when the cross-flow fan 401 is set to the low speed setting or the silent speed setting (second or first speed setting), the supplementary air fan 201 can be controlled to operate at a low speed setting (sixth speed setting).

[0092] The embodiments of the present invention control the speed of the air supply fan in the above-mentioned air supply device based on the speed setting of the cross-flow fan, which can control the speed setting of the air supply fan in the above-mentioned air supply device more flexibly and efficiently.

[0093] Based on the above embodiments, the rotation direction of the cross-flow fan blades, the rotation direction of the supplementary air fan blades, the direction of the air blown out or drawn in by the supplementary air fan, and the speed at which the supplementary air fan rotates around the inner diameter of the corresponding air outlet are controlled based on the operating mode and frequency. This includes: when the air conditioner is in cooling mode, determining a first target speed based on the frequency.

[0094] 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 can be determined by numerical calculation based on the frequency H of the compressor in the air conditioner.

[0095] Alternatively, the compressor frequency H can be used as the first target speed H1, i.e., H1 = H.

[0096] 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 at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet is controlled to achieve the first target speed.

[0097] Specifically, while controlling the fan speed of the air supply fan 201 based on the fan speed setting of the cross-flow fan 401, when the air conditioner is in cooling mode, the fan blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate clockwise, and the air supply fan 201 can be controlled to rotate around the inner diameter of the corresponding air outlet 204 at a first target speed H1. This allows the air supply fan to rotate faster around the inner diameter of the corresponding air outlet 204 as the compressor frequency increases, thereby improving the air delivery effect of the air conditioner when the compressor frequency is increased.

[0098] It should be noted that, in this embodiment of the invention, the angle between the central axis of the projection of the air supply fan 201 onto the plane where the air outlet 204 is located and the central axis of the air outlet 204 in the vertical upward direction in the clockwise direction can be used as the rotation angle of the air supply fan 201 relative to the first rotation axis.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] Accordingly, when the air conditioner is in cooling mode, the blowing angle of the supplementary air fan 201 is between 0° and 90° and between 270° and 0°.

[0107] This invention, in its embodiment, controls the fan speed of the air supply fan based on the fan speed setting of the cross-flow fan. When the air conditioner is in cooling mode, it determines a first target speed based on the compressor frequency and controls the blades of both the cross-flow fan and the air supply fan to rotate clockwise. It also controls the angle between the direction of the air blown out by the air supply fan and the vertical upward direction to be less than 90°, and controls the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet to achieve the first 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.

[0108] Based on the above embodiments, the rotation direction of the blades of the cross-flow fan 401 and the supplementary air fan 201, the direction of the air blown out or drawn in by the supplementary air fan 201, and the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet are controlled based on the operating mode and frequency. This includes: when the air conditioner is in heating mode, determining a second target speed based on the frequency.

[0109] Specifically, after obtaining the operating mode of the air conditioner, if the operating mode of the air conditioner is heating mode, the second target speed H2 can be determined by numerical calculation based on the frequency H of the compressor in the air conditioner.

[0110] Alternatively, the compressor frequency H can be used as the second target speed H2, i.e., H2 = H.

[0111] It should be noted that the first target speed H1 and the second target speed H2 can be the same or different.

[0112] Control the blades of the cross-flow fan and the air supply fan to rotate clockwise, control the angle between the direction of the air blown out by the air supply fan and the vertical downward direction to be less than 90°, and control the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet to achieve the second target speed.

[0113] Specifically, while controlling the fan speed of the air supply fan 201 based on the fan speed setting of the cross-flow fan 401, when the air conditioner is in heating mode, the fan blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate clockwise, and the air supply fan 201 can be controlled to rotate around the inner diameter of the corresponding air outlet 204 at a second target speed H2. This allows the air supply fan to rotate around the inner diameter of the corresponding air outlet 204 faster as the compressor frequency increases, thereby improving the heat exchange effect of the air conditioner when the compressor frequency is increased.

[0114] 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. 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°). That is, 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°. This allows the air conditioner to blow hot air downwards towards the reference horizontal plane in heating mode, thereby 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.

[0115] 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°.

[0116] This invention, in its embodiment, controls the fan speed of the air supply fan based on the fan speed setting of the cross-flow fan. When the air conditioner is in heating mode, it determines a second target speed based on the compressor frequency and controls the blades of both the cross-flow fan and the air supply fan to rotate clockwise. It also controls the angle between the direction of the air blown out by the air supply fan and the vertically downward direction to be less than 90°, and controls the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet to achieve the second target speed. This improves the air delivery effect of the air conditioner in heating mode while increasing the compressor frequency, reduces air conditioner noise, and improves the heating effect by controlling the air conditioner to blow hot air downwards in heating mode, allowing the less dense hot air to naturally flow upwards, thus enhancing user experience.

[0117] Based on the above embodiments, after controlling the air supply fan speed based on the cross-flow fan speed setting, the method further includes: when the air conditioner is in heating mode, correcting the air supply fan speed setting based on frequency.

[0118] Specifically, in this embodiment of the invention, when the air conditioner is in heating mode, after controlling the fan speed of the air supply fan 201 based on the fan speed of the cross-flow fan 401, the fan speed of the air supply fan 201 can be corrected based on the compressor frequency, so that the fan speed of the air supply fan 201 is appropriately reduced. This reduces the air blowing distance of the air conditioner.

[0119] Based on the frequency H of the compressor in the air conditioner, the fifth target speed H5 can be determined through numerical calculation. After controlling the fan speed of the supplementary air fan 201 based on the fan speed setting of the cross-flow fan 401, the fan speed of the supplementary air fan 201 can be controlled to achieve the fifth target speed H5.

[0120] The fifth target speed H5 can be the product of the compressor frequency H and the first preset value x1, i.e., H5 = H × x1. The first preset value x1 can be between 4 and 6, for example, the first preset value x1 can be 4, 5 or 6.

[0121] Preferably, the first preset value x1 can be 5, i.e., H5 = H × 5.

[0122] In this embodiment of the invention, when the air conditioner is in heating mode, after controlling the fan speed of the air supply fan based on the fan speed of the cross-flow fan, the fan speed of the air supply fan is corrected based on the compressor frequency to reduce the fan speed. This can shorten the air blowing distance of the air conditioner in heating mode, preventing the user from feeling that the air conditioner is blowing out cool air and improving the user's perception.

[0123] Based on the above embodiments, the rotation direction of the blades of the cross-flow fan and the supplementary air fan, the direction of the air blown out or drawn in by the supplementary air fan, and the speed at which the supplementary air fan rotates around the inner diameter of the corresponding air outlet are controlled based on the operating mode and frequency. This includes: when the air conditioner is in the air supply mode, determining a third target speed based on the frequency.

[0124] Specifically, after obtaining the operating mode of the air conditioner, if the operating mode of the air conditioner is cooling mode, the third target speed H3 can be determined by numerical calculation based on the frequency H of the compressor in the air conditioner.

[0125] Alternatively, the compressor frequency H can be used as the third target speed H3, i.e., H3 = H.

[0126] It should be noted that the third target speed H3 may be the same as or different from the first target speed H1 and / or the second target speed H2.

[0127] Control the blades of the cross-flow fan and the air supply fan to rotate clockwise, control the angle between the direction of the air blown out by the air supply fan and the vertical downward direction to be less than 90°, and control the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet to achieve the third target speed.

[0128] Specifically, while controlling the fan speed of the air supply fan 201 based on the fan speed setting of the cross-flow fan 401, when the air conditioner is in the air supply mode, the fan blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate clockwise, and the air supply fan 201 can be controlled to rotate around the inner diameter of the corresponding air outlet 204 at a third target speed H3. This allows the air supply fan to rotate faster around the inner diameter of the corresponding air outlet 204 as the compressor frequency increases, thereby improving the air supply effect of the air conditioner when the compressor frequency is increased.

[0129] It should be noted that, in the embodiment of the present invention, when the air conditioner is in the air supply 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 supply fan 201 blowing out gas and the vertical downward direction is controlled to be less than 90°, so that the air conditioner blows natural wind downward to the reference horizontal plane in the air supply mode, thereby further increasing the air circulation in the room.

[0130] 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°.

[0131] This invention, in its embodiment, controls the fan speed of the air supply fan based on the fan speed setting of the cross-flow fan. When the air conditioner is in ventilation mode, it determines a third target speed based on the compressor frequency and controls the blades of both the cross-flow fan and the air supply fan to rotate clockwise. It also controls the angle between the direction of the air blown out by the air supply fan and the vertically downward direction to be less than 90°, and controls the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet to achieve the third target speed. This improves the air supply effect of the air conditioner in ventilation mode by increasing the compressor frequency, reduces air conditioner noise, increases indoor air circulation by controlling the air conditioner to blow natural air downwards, and enhances user experience.

[0132] Based on the above embodiments, after controlling the air supply fan speed based on the cross-flow fan speed setting, the method further includes: when the air conditioner is in the air supply mode, correcting the air supply fan speed setting based on the frequency.

[0133] Specifically, in order to improve the long-distance air delivery capability of the air conditioner in the air supply mode, this embodiment of the invention, when the air conditioner is in the air supply mode, can further control the air speed of the air supply fan 201 based on the fan speed of the cross-flow fan 401, and then correct the fan speed of the air supply fan 201 based on the compressor frequency, so as to appropriately increase the fan speed of the air supply fan 201. This can increase the air blowing distance of the air conditioner by increasing the fan speed of the air supply fan 201.

[0134] Based on the frequency H of the compressor in the air conditioner, the sixth target speed H6 can be determined through numerical calculation. After controlling the fan speed of the supplementary air fan 201 based on the fan speed setting of the cross-flow fan 401, the fan speed of the supplementary air fan 201 can be controlled to achieve the sixth target speed H6.

[0135] The sixth target speed H6 can be the product of the compressor frequency H and the second preset value x2, i.e., H6 = H × x2. The second preset value x2 can be between 6 and 8, for example, the second preset value x2 can be 6, 7 or 8.

[0136] Preferably, the second preset value x2 can be 7, that is, H6 = H × 7.

[0137] In this embodiment of the invention, when the air conditioner is in the air supply mode, after controlling the speed of the air supply fan based on the speed of the cross-flow fan, the air supply fan speed is adjusted based on the compressor frequency to increase the air supply fan speed. This increases the air blowing distance of the air conditioner in the air supply mode, further increases the air circulation in the room, and improves the user experience.

[0138] Based on the above embodiments, the rotation direction of the cross-flow fan blades, the rotation direction of the supplementary air fan blades, the direction of the air blown out or drawn in by the supplementary air fan, and the speed at which the supplementary air fan rotates around the inner diameter of the corresponding air outlet are controlled based on the operating mode and frequency. This includes: when the air conditioner is in the target operating mode, determining a fourth target speed based on the frequency.

[0139] 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 fourth target speed H4 can be determined by numerical calculation based on the frequency H of the compressor in the air conditioner.

[0140] Alternatively, the compressor frequency H can be used as the fourth target speed H4, i.e., H4 = H.

[0141] It should be noted that the fourth target speed H4 can be the same as at least one of the first target speed H1, the second target speed H2 and the third target speed H3, or it can be different from all of the first target speed H1, the second target speed H2 and the third target speed H3.

[0142] Control the blades of the cross-flow fan and the air supply fan to rotate counterclockwise, control the angle between the direction of the air intake fan and the vertical upward direction to be less than 90°, and control the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet to achieve the fourth target speed.

[0143] The target modes include: defrosting mode or self-cleaning mode.

[0144] 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 blades of the air supply fan 201 can be controlled to rotate counterclockwise, and the speed at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet 204 can be controlled to execute the fourth target speed H4. This allows the air supply fan to rotate faster around the inner diameter of the corresponding air outlet 204 as the compressor frequency increases, thereby improving the defrosting or self-cleaning effect of the air conditioner when the compressor frequency is increased.

[0145] 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.

[0146] 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 0°.

[0147] This invention, when the air conditioner is in target mode, determines a fourth 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 speed at which the supplementary air fan rotates around the inner diameter of the corresponding air outlet to achieve the fourth target speed. Furthermore, it controls the angle between the direction of the supplementary air fan's gas intake and the vertically upward direction to be less than 90°. This allows for control of the amount of gas the air conditioner draws in during target mode based on the compressor frequency, improving the air intake effect during target mode. By controlling the air conditioner to draw in gas from above the reference horizontal plane, it avoids affecting the air conditioner's performance during target mode and reduces air conditioner noise.

[0148] Based on the above embodiments, the rotation of each supplementary air fan 201 around the inner diameter of each air outlet 204 is synchronized.

[0149] In this embodiment of the invention, each air supply fan rotates synchronously around the inner diameter of each air outlet, 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.

[0151] The data acquisition module 901 is used to acquire the operating mode of the air conditioner, the frequency of the compressor in the air conditioner, and the fan speed of the cross-flow fan when the air conditioner is started.

[0152] The air supply control module 902 is used to control the air speed of the air supply fan based on the air speed setting of the cross-flow fan. Based on the operating mode and frequency, it controls the rotation direction of the blades of the cross-flow fan and the air supply fan, the direction of the air blown out or drawn in by the air supply fan, and the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet.

[0153] Specifically, the data acquisition module 901 and the air supply control module 902 are electrically connected.
