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] In existing technologies, traditional air conditioners can quickly regulate the ambient temperature of a localized area near the unit after startup, but their regulation rate for other areas is slower. Therefore, for a period after startup, significant temperature differences can easily occur between different spaces, resulting in poor user comfort. Furthermore, traditional air conditioners typically operate at a fixed fan speed, which, in real-world scenarios, is insufficient for optimal temperature control, leading to low efficiency in temperature regulation. Therefore, how to achieve more flexible control of the air conditioner after startup, enabling more efficient and balanced regulation of indoor temperature, is a pressing technical problem that needs to be solved in this field.

[0057] 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.

[0058] 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.

[0059] It should be noted that the control method for the air conditioner provided by the present invention is applied within a preset time period from the moment the air conditioner is started; the air conditioner includes multiple air outlets; each air outlet is provided with a supplementary air fan, the supplementary air fan can rotate around the inner diameter of the corresponding air outlet, and the supplementary air fan can also rotate relative to the first rotation axis, the first rotation axis is the central axis of the support structure on which the supplementary air fan is installed, and the central axis is perpendicular to the plane where the air outlet is located.

[0060] Specifically, in order to achieve more efficient and balanced regulation of indoor ambient temperature after the air conditioner is turned on, the air conditioner can be specially controlled based on the control method of the present invention within a preset time after the air conditioner is turned on. This can increase the air blowing distance of the air conditioner within the preset time after the air conditioner is turned on, improve the heat exchange efficiency and heat exchange capacity of the air conditioner, and achieve more efficient and balanced regulation of indoor ambient temperature after the air conditioner is turned on.

[0061] It should be noted that the aforementioned preset duration can be determined based on prior knowledge; for example, the preset duration can be 10 minutes, 20 minutes, or 30 minutes. The specific value of the preset duration is not limited in this embodiment of the invention.

[0062] Optionally, the air conditioner control method provided by the present invention can also be used within a preset time period from the moment the air conditioner switches its operating mode, thereby increasing the air blowing distance of the air conditioner within the preset time period after the air conditioner switches its operating mode, improving the heat exchange efficiency and heat exchange capacity of the air conditioner, and realizing more efficient and balanced regulation of the indoor ambient temperature after the air conditioner switches its operating mode.

[0063] Air conditioner operating modes typically include: 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 blown out by the air conditioner can reach during operation.

[0064] It should be noted that traditional air conditioners typically rely on built-in centrifugal or cross-flow fans for airflow. Centrifugal fans have higher air pressure, so when an air conditioner uses a built-in centrifugal fan, the airflow distance is relatively long, but the user experiences a stronger draft and a less comfortable experience. Cross-flow fans have lower air pressure, resulting in a weaker draft for the user, but the airflow distance is relatively short.

[0065] 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 the airflow distance of the air conditioner without increasing the user's airflow sensation.

[0066] Figure 1 This is one of the perspective views of the air conditioner in the air conditioner control method provided by the present invention. Figure 2 This is a front view of the air conditioner in the air conditioner control method provided by the present invention. Figure 3 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 1 , Figure 2 and Figure 3 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 equipped with a supplementary air fan 201, which can rotate clockwise or counterclockwise around the inner diameter of the corresponding air outlet 204. The supplementary air fan 201 is located outside the housing 203.

[0069] It should be noted that the structures of each air outlet 204 are identical. The following description focuses on one air outlet 204 and the air supply fan 201 disposed at that air outlet 204 to illustrate the air conditioner and air conditioner control method provided by the present invention. The air outlet 204 and 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 aforementioned 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. 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 air delivery direction of 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 during the rotation of the air supply fan 201 around the inner diameter of the corresponding 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 along the inner diameter of its respective 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] Figure 4 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 4 The control method of the air conditioner of the present invention is described. For example... Figure 4 As shown, the method includes: step 4001, obtaining the operating mode of the air conditioner and the frequency of the compressor in the air conditioner.

[0083] It should be noted that the execution subject of this embodiment of the invention is the control device of an air conditioner.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] In this embodiment of the invention, when the air conditioner is started, the operating mode of the air conditioner 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 controller of the air conditioner; or, the operating mode of the air conditioner can be obtained according to the working status of the compressor; or the frequency of the compressor can be obtained by using the controller of the air conditioner.

[0088] 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.

[0089] It is understandable that the compressor frequency changes dynamically.

[0090] Step 4002: Based on the operating mode, control the rotation direction of the air supply fan 201 blades and the way the air supply fan 201 rotates relative to the first rotation axis.

[0091] Specifically, after obtaining the operating mode of the air conditioner, the rotation direction of the blades of the cross-flow fan 401 and the rotation direction of the blades of the supplementary air fan 201 can be controlled based on the operating mode of the air conditioner.

[0092] 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.

[0093] After obtaining the operating mode of the air conditioner, the rotation of the air supply fan 201 relative to the first rotating axis can also be controlled based on the operating mode of the air conditioner.

[0094] Step 4003: Based on the operating mode and the air delivery direction of the supplementary air fan 201, as well as the preset speed or frequency, control the fan blade speed of 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.

[0095] The reference horizontal plane is the horizontal plane where the first axis of rotation is located.

[0096] Specifically, since the air supply fan 201 rotates relative to the first rotation axis within a preset time period starting from the start of the air conditioner, the relative position of the air supply fan 201 is different for any two adjacent moments within the preset time period starting from the start of the air conditioner.

[0097] For each moment within a preset time period starting from the start of the air conditioner, condition judgments can be made based on the air conditioner's operating mode and the air delivery direction of the supplementary air fan at each moment. Based on the result of the condition judgment and the preset speed, the fan speed of the supplementary air fan 201 at each moment can be controlled more flexibly. Based on the result of the condition judgment and the frequency of the compressor, the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can be controlled more flexibly.

[0098] 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.

[0099] 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.

[0100] It should be noted that when the air conditioner is running, the cross-flow fan 401 can be controlled to execute a preset speed H0.

[0101] This invention, within a preset time period starting from the moment the air conditioner is started, controls the rotation direction of the air supply fan blades and the way the air supply fan rotates relative to the first rotation axis based on the air conditioner's operating mode. Based on the air conditioner's operating mode, the air supply fan's airflow direction, and a preset speed or the compressor frequency in the air conditioner, the invention controls the air supply fan's blade speed and the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet. This allows for more flexible control of the air conditioner within a preset time period after startup, based on the actual operating conditions. It increases the airflow distance, improves the air conditioner's heat exchange efficiency and capacity, and enables more efficient and balanced regulation of the indoor ambient temperature within a short time after startup. This improves user experience and reduces the air conditioner's energy consumption.

[0102] Based on the above embodiments, and based on the operating mode, controlling the rotation direction of the air supply fan 201 blades and the way the air supply fan 201 rotates relative to the first rotation axis includes: when the air conditioner's operating mode is cooling mode or heating mode, controlling the air supply fan 201 blades to rotate clockwise and controlling the air supply fan 201 to rotate circumferentially relative to the first rotation axis.

[0103] Specifically, within a preset time period from the moment the air conditioner is started, if the air conditioner is in cooling mode or heating mode, the fan blades of the air supply fan 201 can be controlled to rotate clockwise and the air supply fan 201 can be controlled to rotate 360° around the first rotation axis, thereby enabling the air supply fan 201 to rotate 360° to deliver air, improving the heat exchange efficiency and heat exchange capacity of the air conditioner in cooling mode.

[0104] It should be noted that within a preset time period from the moment the air conditioner is started, if the air conditioner is in cooling or heating mode, the blades of the cross-flow fan 401 can be controlled to rotate clockwise.

[0105] When the air conditioner is in the air supply mode, the blades of the air supply fan 201 are controlled to rotate clockwise, and the air supply fan 201 is controlled to reciprocate relative to the first rotation axis below the reference horizontal plane.

[0106] Specifically, within a preset time period from the start of the air conditioner, if the air conditioner is in the air supply mode, the blades of the air supply fan 201 can be controlled to rotate clockwise and the air supply fan 201 can be controlled to reciprocate relative to the first rotation axis below the reference horizontal plane, so that the air supply fan 201 can swing and supply air downwards to the reference horizontal plane, thereby improving the air supply effect of the air conditioner.

[0107] It should be noted that, within a preset time period from the moment the air conditioner is started, if the air conditioner is in the air supply mode, the blades of the cross-flow fan 401 can be controlled to rotate clockwise.

[0108] When the air conditioner is in the target mode, the blades of the air supply fan 201 are controlled to rotate counterclockwise, and the air supply fan 201 is controlled to rotate relative to the first rotation axis to above the reference horizontal plane.

[0109] The target modes include: defrosting mode or self-cleaning mode.

[0110] Specifically, within a preset time period from the moment the air conditioner is started, if the air conditioner is in defrost mode or self-cleaning mode, the fan blades of the air supply fan 201 can be controlled to rotate counterclockwise and the air supply fan 201 can be controlled to rotate above the reference horizontal plane. This allows the air supply fan 201 to swing and draw in air from above the reference horizontal plane, thereby avoiding affecting the air conditioner's performance in the target mode and reducing the noise of the air conditioner.

[0111] It should be noted that if the air conditioner is in defrost mode or self-cleaning mode within a preset time period from the moment the air conditioner is started, the blades of the cross-flow fan 401 can be controlled to rotate counterclockwise.

[0112] This invention, in its embodiments, controls the air supply fan to rotate 360° to deliver air when the air conditioner is in cooling or heating mode; controls the air supply fan to swing downwards towards a reference horizontal plane when the air conditioner is in ventilation mode; and controls the air supply fan to swing upwards from above the reference horizontal plane to draw in air when the air conditioner is in defrost or self-cleaning mode. This allows for more flexible control over the rotation direction of the air supply fan blades and the way they rotate relative to the first rotation axis, thereby improving the heat exchange efficiency, heat exchange capacity, and air delivery effect of the air conditioner in different operating modes. Ultimately, this enables more efficient and balanced regulation of the indoor ambient temperature within a short time after the air conditioner is started.

[0113] Based on the above embodiments, based on the operating mode and the air delivery direction of the supplementary air fan 201, as well as the preset speed or frequency, controlling the fan blade speed of 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 includes: when the air conditioner is in cooling mode and the angle between the air delivery direction of the supplementary air fan 201 and the vertical upward direction is not greater than 90°, controlling the fan blade speed of the supplementary air fan 201 to execute a first target speed, and controlling the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 to execute a second target speed.

[0114] The first and third target speeds are determined based on preset speeds, with the first target speed being greater than the third target speed; the second and fourth target speeds are determined based on frequency, with the second target speed being greater than the fourth target speed.

[0115] It should be noted that after obtaining the air conditioner's operating mode, if the air conditioner's operating mode is cooling mode, the first target speed H1 and the third target speed H3 can be determined by numerical calculation based on the preset speed H0. The second target speed H2 and the fourth target speed H4 can be determined by numerical calculation based on the compressor frequency H.

[0116] Optionally, the first target rotational speed H1 can be the product of a preset rotational speed H0 and a first preset value x1, i.e., H1 = H0 × x1. The first preset value x1 can range from 1 / 3 to 1, for example, the first preset value x1 can be 1 / 3, 1 / 2 or 1.

[0117] Preferably, the first preset value x1 can be 1 / 2, that is, H1 = H0 × 1 / 2.

[0118] Optionally, the third target speed H3 can be the product of the preset speed H0 and the third preset value x3, i.e., H3 = H0 × x3. The value of the third preset value x3 can be between 1 / 4 and 1 / 2, for example, the third preset value x3 can be 1 / 4, 1 / 3 or 1 / 2.

[0119] Preferably, the third preset value x3 can be 1 / 3, that is, H3 = H0 × 1 / 3.

[0120] Optionally, the second target speed H2 can be the product of the compressor frequency H and the second preset value x2, i.e., H2 = H × x2. The value of the second preset value x2 can be between 1 and 3, for example, the second preset value x2 can be 1, 2 or 3.

[0121] Preferably, the second preset value x2 can be 2, that is, H2 = H × 2.

[0122] Optionally, the fourth target speed H4 can be the product of the compressor frequency H and the fourth preset value x4, i.e., H4 = H × x4. The value of the fourth preset value x4 can be between 1 / 2 and 3 / 2, for example, the fourth preset value x4 can be 1 / 2, 1 or 3 / 2.

[0123] Preferably, the fourth preset value x4 can be 1, that is, H4 = H.

[0124] 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.

[0125] In this embodiment of the invention, when the supplementary air fan 210 blows out gas, the angle between the projection of the air supply direction of 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 air supply 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 supplementary air fan 201 drawing in gas 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 supplementary air fan 201 drawing in gas.

[0126] 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 the air supply angle of the air supply fan 201 is 0° (360°), the perspective view of the air conditioner is as follows. Figure 5 As shown.

[0127] 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 air supply angle of the air supply fan 201 is 90°, the perspective view of the air conditioner is as follows. Figure 6 As shown.

[0128] 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 the air supply angle of the air supply fan 201 is 180°, the perspective view of the air conditioner is as follows. Figure 7 As shown.

[0129] Figure 8This 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 the air supply angle of the air supply fan 201 is 270°, the perspective view of the air conditioner is as follows. Figure 8 As shown.

[0130] 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 air supply direction of the supplementary air fan 201 and the vertical upward direction is not greater than 90°, that is, the supplementary air fan 201 blows gas upward to 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 air supply direction of the supplementary air fan 201 and the vertical downward direction is less than 90°, that is, the supplementary air fan 201 blows gas downward to the reference horizontal plane.

[0131] The rotation angle of the air supply fan 201 relative to the first rotation axis can be obtained in various ways, such as by using an angle sensor.

[0132] When the air conditioner is in cooling mode, after obtaining the rotation angle of the air supply fan 201 relative to the first rotation axis, if the rotation angle of the air supply fan 201 relative to the first rotation axis is within [0°, 90°] and [270°, 360°], it means that the angle between the air supply fan 201's air delivery direction and the vertical upward direction is not greater than 90°. The fan speed of the air supply fan 201 can be controlled to achieve the first target speed, so that the air conditioner delivers cold air at a higher wind speed to the upper part of the reference horizontal plane, realizing that the denser cold air flows naturally downward, thereby improving the cooling effect of the air conditioner. The rotation speed of the air supply fan 201 around the inner diameter of the corresponding air outlet 204 can also be controlled to achieve the second target speed, so that the air flow speed above the reference horizontal plane is faster, thereby reducing the indoor ambient temperature in a short time after the air conditioner is turned on.

[0133] When the air conditioner is in cooling mode and the angle between the air supply direction of the air supply fan 201 and the vertical downward direction is less than 90°, the fan speed of the air supply fan 201 is controlled to execute the third target speed, and the speed at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet 204 is controlled to execute the fourth target speed.

[0134] Specifically, when the air conditioner is in cooling mode, after obtaining the rotation angle of the air supply fan 201 relative to the first rotation axis, if the rotation angle of the air supply fan 201 relative to the first rotation axis is within (90°, 270°), it means that the angle between the air supply fan 201's air delivery direction and the vertical downward direction is less than 90°. The third target speed of the air supply fan 201 can be controlled to deliver cool air at a moderate speed to the area below the reference horizontal plane, avoiding excessive air delivery speed from causing discomfort to the user. The fourth target speed can also be controlled to rotate the air supply fan 201 around the inner diameter of the corresponding air outlet 204, so that the air flow speed below the reference horizontal plane is moderate, thereby achieving a short-term reduction in the indoor ambient temperature after the air conditioner is turned on.

[0135] It should be noted that when the air conditioner is in cooling mode, the cross-flow fan 401 can be controlled to execute a preset speed H0.

[0136] This invention, by adjusting the air supply fan's direction and preset speed or compressor frequency when the air conditioner is in cooling mode, allows for more flexible control of the fan blade speed and the speed at which the air supply fan rotates around the corresponding air outlet's inner diameter. This improves the air conditioner's cooling effect, prevents excessive airflow from causing user discomfort, achieves a more balanced and efficient reduction of indoor ambient temperature after the air conditioner is started, and reduces the air conditioner's energy consumption.

[0137] Based on the above embodiments, based on the operating mode and the air delivery direction of the supplementary air fan 201, as well as the preset speed or frequency, the control of the fan blade speed of 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 includes: when the air conditioner is in heating mode and the angle between the air delivery direction of the supplementary air fan 201 and the vertical upward direction is not greater than 90°, controlling the fan blade speed of the supplementary air fan 201 to execute the fifth target speed, and controlling the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 to execute the sixth target speed.

[0138] The fifth target speed is determined based on a preset speed, and the third target speed is greater than the fifth target speed; the sixth target speed is determined based on frequency, and the fourth target speed is greater than the sixth target speed.

[0139] It should be noted that after obtaining the air conditioner's operating mode, if the air conditioner's operating mode is heating mode, the fifth target speed H5 can be determined by numerical calculation based on the preset speed H0, and the sixth target speed H6 can be determined by numerical calculation based on the compressor frequency H.

[0140] Optionally, the fifth target speed H5 can be the product of the preset speed H0 and the fifth preset value x5, i.e., H5 = H0 × x5. The value of the fifth preset value x5 can be between 1 / 5 and 1 / 3, for example, the fifth preset value x5 can be 1 / 5, 1 / 4 or 1 / 3.

[0141] Preferably, the fifth preset value x5 can be 1 / 4, that is, H5 = H0 × 1 / 4.

[0142] Optionally, the sixth target speed H6 can be the product of the compressor frequency H and the sixth preset value x6, i.e., H6 = H × x6. The value of the sixth preset value x6 can be between 1 and 1 / 3, for example, the sixth preset value x6 can be 1, 1 / 2 or 1 / 3.

[0143] Preferably, the sixth preset value x6 can be 2, i.e., H2 = H × 1 / 2.

[0144] Optionally, the fourth target speed H4 can be the product of the compressor frequency H and the fourth preset value x4, i.e., H4 = H × x4. The value of the fourth preset value x4 can be between 1 and 1 / 3, for example, the fourth preset value x4 can be 1, 1 / 2 or 1 / 3.

[0145] Preferably, the fourth preset value x4 can be 1 / 2, that is, H2 = H × 1 / 2.

[0146] Specifically, when the air conditioner is in heating mode, after obtaining the rotation angle of the supplementary air fan 201 relative to the first rotation axis, if the rotation angle of the supplementary air fan 201 relative to the first rotation axis is within [0°, 90°] and [270°, 360°], it means that the angle between the air supply direction of the supplementary air fan 201 and the vertical upward direction is not greater than 90°. The fan speed of the supplementary air fan 201 can be controlled to execute the fifth target speed supplementary air fan, so that the air conditioner delivers hot air at a lower wind speed above the reference horizontal plane. The rotation speed of the supplementary air fan 201 around the inner diameter of the corresponding air outlet 204 can also be controlled to execute the sixth target speed, so that the air flow speed above the reference horizontal plane is slower, thereby achieving a short time increase in indoor ambient temperature after the air conditioner is turned on.

[0147] When the air conditioner is in heating mode and the angle between the air supply fan 201 and the vertical downward direction is less than 90°, the fan blade speed of the air supply fan 201 is controlled to achieve the first target speed, and the rotation speed of the air supply fan 201 around the inner diameter of the corresponding air outlet 204 is controlled to achieve the second target speed.

[0148] When the air conditioner is in heating mode, after obtaining the rotation angle of the air supply fan 201 relative to the first rotation axis, if the rotation angle of the air supply fan 201 relative to the first rotation axis is within (90°, 270°), it means that the angle between the air supply direction of the air supply fan 201 and the vertical downward direction is less than 90°. The fan speed of the air supply fan 201 can be controlled to achieve the first target speed, so that the air conditioner delivers hot air at a higher wind speed to the lower part of the reference horizontal plane, realizing that the less dense hot air flows upward naturally, thereby improving the heating effect of the air conditioner. The rotation speed of the air supply fan 201 around the inner diameter of the corresponding air outlet 204 can also be controlled to achieve the second target speed, so that the air flow speed below the reference horizontal plane is moderate, thereby achieving a short time increase in indoor ambient temperature after the air conditioner is turned on.

[0149] Optionally, after a preset time from the start of the air conditioner, the rotation direction of the air supply fan 201 blades, the way the air supply fan 201 rotates relative to the first rotation axis, the speed of the air supply fan 201 blades, and the speed at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet can be controlled based on user input.

[0150] After a preset time since the air conditioner is started, when the air conditioner is in cooling or heating mode, the fan speed of the air supply fan 201 can be controlled to execute a third target speed, 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 a fourth target speed.

[0151] It should be noted that when the air conditioner is in heating mode, the cross-flow fan 401 can be controlled to execute a preset speed H0.

[0152] In the embodiments of the present invention, when the air conditioner is in heating mode, the fan blade speed and the speed at which the fan rotates around the inner diameter of the corresponding air outlet are more flexibly controlled based on the air delivery direction of the air supply fan and the preset speed or the frequency of the compressor. This can improve the heating effect of the air conditioner, achieve a more balanced and efficient increase in indoor ambient temperature after the air conditioner is started, and reduce the energy consumption of the air conditioner.

[0153] Based on the above embodiments, after controlling the fan blade speed of the air supply fan 201 and the speed at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet 204, based on the operating mode, the air supply direction of the air supply fan 201, and the preset speed or frequency, the method further includes: obtaining the location information of the indoor user.

[0154] Specifically, in this embodiment of the invention, the location information of indoor users can be obtained in a variety of ways. For example, a thermal imaging sensor can be used to locate indoor users, and the location information of indoor users can be further obtained based on the location results; or, machine vision and deep learning technologies can be used to obtain the location information of indoor users.

[0155] It should be noted that, for each moment within a preset time period starting from the moment the air conditioner is turned on, the embodiments of the present invention can obtain the location information of the indoor user at each moment in the above manner.

[0156] Based on the air conditioner's operating mode, location information, and the rotation angle of the supplementary air fan 201 relative to the first rotation axis, as well as the preset speed and frequency, the fan blade speed of 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 are corrected.

[0157] Specifically, for each moment within a preset time period starting from the start of the air conditioner, after obtaining the location information of the indoor user at each moment, condition judgments can be made based on the air conditioner's operating mode, the air delivery direction of the supplementary air fan at each moment, and the location information of the indoor user at each moment. Based on the result of the condition judgment and the preset speed, the fan blade speed of the supplementary air fan 201 at each moment can be corrected. Based on the result of the condition judgment and the frequency of the compressor, the rotation speed of the supplementary air fan 201 around the inner diameter of the corresponding air outlet 204 can be corrected, thereby preventing the air delivery speed of the supplementary air fan 201 from being too high and causing discomfort to the user.

[0158] This invention, by adjusting the fan blade speed and the rotation speed of the air supply fan around the inner diameter of the corresponding air outlet based on the air conditioner's operating mode, the indoor user's location information, and the rotation angle of the air supply fan relative to the first rotation axis, can prevent the air supply fan from blowing too fast and causing discomfort to the user, thus improving the user's perception.

[0159] Based on the above embodiments, based on the air conditioner's operating mode, location information, and the rotation angle of the supplementary air fan 201 relative to the first rotation axis, the fan blade speed of 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 are corrected, including: determining the target angle range based on the location information.

[0160] Specifically, after obtaining the location information of indoor users, the target area and its location information can be determined based on this information. If the air supply area of ​​the air conditioner overlaps with the target area, it indicates that the indoor users can feel the air supply from the air conditioner.

[0161] Optionally, in this embodiment of the invention, the target area and the location information of the target area can be determined based on the location information of the indoor user through numerical calculation or other methods. For example, a circular area can be determined as the target area with the location of the indoor user as the center and a preset value as the radius. The location information of the target area can be determined based on the location information of the indoor user. The preset value can be 1 meter.

[0162] After determining the target area and its location, the target angle range can be determined through numerical calculations. When the rotation angle of the supplementary air fan 201 relative to the first rotation axis falls within the aforementioned target angle range, the air supply area of ​​the air conditioner coincides with the target area, and indoor users can feel the air supply from the air conditioner.

[0163] When the air conditioner is in cooling mode and the rotation angle is within the target angle range, the fan speed of the supplementary air fan 201 is controlled to execute the fifth target speed, and the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 is controlled to execute the sixth target speed.

[0164] Specifically, when the air conditioner is in cooling mode, if the rotation angle of the supplementary air fan 201 relative to the first rotation axis is within the target angle range, the fan speed of the supplementary air fan 201 can be controlled to execute the fifth target speed supplementary air fan, and the rotation speed of the supplementary air fan 201 around the inner diameter of the corresponding air outlet 204 can be controlled to execute the sixth target speed, thereby preventing the air supply speed of the supplementary air fan 201 from being too high and causing discomfort to the user.

[0165] When the air conditioner is in heating mode and the rotation angle is within the target angle range, the fan speed of the supplementary air fan 201 is controlled to execute the third target speed, and the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 is controlled to execute the fourth target speed.

[0166] Specifically, when the air conditioner is in heating mode, if the rotation angle of the supplementary air fan 201 relative to the first rotation axis is within the target angle range, the fan speed of the supplementary air fan 201 can be controlled to execute the third target speed supplementary air fan, and the rotation speed of the supplementary air fan 201 around the inner diameter of the corresponding air outlet 204 can be controlled to execute the fourth target speed, thereby preventing the air supply speed of the supplementary air fan 201 from being too high and causing discomfort to the user.

[0167] It is understandable that cold air is more likely to cause discomfort to the human body. Therefore, when the air supply area of ​​the air conditioner overlaps with the target area mentioned above, the air speed of the air conditioner delivering hot air can be greater than the air speed of the air conditioner delivering cold air.

[0168] This invention, through determining the target angle range based on the location information of indoor users, then corrects the fan blade speed and the rotation speed of the air supply fan around the corresponding air outlet inner diameter based on the air conditioner's operating mode and whether the rotation angle of the air supply fan relative to the first rotation axis is within the target angle range. This can more accurately prevent the air supply fan from causing user discomfort due to excessive airflow speed without affecting the air conditioner's temperature control effect, thus improving user experience.

[0169] Based on the above embodiments, based on the operating mode and the air supply direction of the supplementary air fan 201, as well as the preset speed or frequency, the fan blade speed of 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 are controlled, including: when the air conditioner's operating mode is the air supply mode, controlling the fan blade speed of the supplementary air fan 201 to cyclically execute the first target speed, the third target speed, and the fifth target speed, and controlling the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 to execute the fourth target speed.

[0170] Specifically, if the air conditioner is in the air supply mode and the operating mode is the air supply mode within a preset time period from the moment the air conditioner is started, the air supply fan 201 is controlled to reciprocate relative to the first rotation axis below the reference horizontal plane. Therefore, when the air conditioner is in the air supply mode, the angle between the air supply direction of the air supply fan 201 and the vertical downward direction is always less than 90°.

[0171] Accordingly, when the air conditioner is in the air supply mode, the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can be controlled to execute the fourth target speed. The speed of the fan blades of the supplementary air fan 201 can be controlled to cyclically execute the first target speed, the third target speed, and the fifth target speed according to a preset cycle duration. For example, when the preset cycle duration is 10 seconds, the speed of the fan blades of the supplementary air fan 201 can be controlled first to execute the first target speed for 10 seconds, then the speed of the fan blades of the supplementary air fan 201 can be controlled to execute the second target speed for 10 seconds, and finally the speed of the fan blades of the supplementary air fan 201 can be controlled to execute the third target speed for 10 seconds, and so on.

[0172] It should be noted that when the air conditioner is in fan-only mode, the cross-flow fan 401 can be controlled to execute a preset speed H0.

[0173] In this embodiment of the invention, when the air conditioner is in the air supply mode, the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet is controlled to execute the fourth target speed. The speed of the air supply fan blades is controlled to cyclically execute the first target speed, the third target speed, and the fifth target speed. This can simulate the effect of natural wind, improve user comfort, and avoid overly cold air supply in the air supply mode.

[0174] It should be noted that when the air conditioner is in target mode, the fan speed of the air supply fan 201 is controlled to execute the third target speed.

[0175] Specifically, if the air conditioner is in target mode for a preset period of time from the moment it is started, the air supply fan 201 is controlled to rotate above the reference horizontal plane. Therefore, when the air conditioner is in target mode, the angle between the air supply fan 201 and the vertical upward direction is always less than 90°.

[0176] Accordingly, when the air conditioner is in the target mode, the fan speed of the air supply fan 201 can be controlled to execute the third target speed, and the rotation angle of the air supply fan 201 relative to the first rotation axis can be controlled to 0°, so that the air conditioner draws in air from above the reference horizontal plane at a medium wind speed, which can avoid affecting the use effect of the air conditioner in the target mode and reduce the noise of the air conditioner.

[0177] Based on the above embodiments, the rotation of each supplementary air fan 201 relative to each first rotation axis is synchronous, and the rotation of each supplementary air fan 201 around the inner diameter of each air outlet 204 is synchronous.

[0178] In this embodiment of the invention, each air supply fan rotates synchronously around the inner diameter of each air outlet, and each air supply fan rotates synchronously relative to the first rotation axis. This can prevent the air supply area of ​​the air conditioner from being dispersed or concentrated, further increase the air supply distance of the air conditioner, improve the heat exchange efficiency and heat exchange capacity of the air conditioner, and achieve more efficient and balanced control of the indoor ambient temperature in a short time after the air conditioner is started.

[0179] Figure 9 This is a structural schematic diagram of the control device for the air conditioner provided by the present invention. The following is in conjunction with… Figure 9 The control device for an air conditioner provided by this invention will be described below. The control device described below can be referred to in correspondence with the control method for an air conditioner provided by this invention described above. It should be noted that the control device for an air conditioner provided by this invention is used within a preset time period from the moment the air conditioner is started. The air conditioner includes multiple air outlets. Each air outlet is provided with a supplementary air fan, which can rotate around the inner diameter of the corresponding air outlet. The supplementary air fan can also rotate relative to a first rotation axis, which is the central axis of the support structure on which the supplementary air fan is installed, and the central axis is perpendicular to the plane where the air outlet is located.

[0180] like Figure 9 As shown, the device includes: a pattern acquisition module 901, a first control module 902, and a second control module 903.

[0181] The mode acquisition module 901 is used to acquire the operating mode of the air conditioner and the frequency of the compressor in the air conditioner;

[0182] The first control module 902 is used to control the rotation direction of the air supply fan blades and the way the air supply fan rotates relative to the first rotation axis based on the operating mode.

[0183] The second control module 903 is used to control the fan blade speed and the speed at which the air supply fan rotates around the inner diameter of the corresponding air outlet, based on the operating mode, the air supply direction of the air supply fan, and the preset speed or frequency.
