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 often insufficient for optimal temperature control in real-world scenarios, leading to low efficiency in regulating indoor temperature. Therefore, achieving a longer airflow distance with a weaker draft, while simultaneously providing more efficient indoor temperature control, is a pressing technical challenge in this field. Summary of the Invention

[0005] This invention provides a control method, device, and air conditioner for an air conditioner, which solves the shortcomings of existing technologies such as difficulty in achieving a long air blowing distance and weak air blowing sensation for users, as well as low efficiency in regulating indoor ambient temperature. The invention achieves a long air blowing distance and weak air blowing sensation for users, and more efficient regulation of indoor ambient temperature.

[0010] According to a control method for an air conditioner provided by the present invention, the step of controlling the air supply device in the air conditioner based on the operating mode, the temperature difference, and the frequency or preset speed includes:

[0018] When the temperature difference is within the first preset range, the fan blade speed of the air supply fan is controlled to execute the first target speed, and the rotation speed of the air supply fan around the inner diameter of the corresponding air outlet is controlled to execute the second target speed.

[0046] 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.

[0047] 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.

[0048] 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 temperature difference between the indoor and outdoor ambient temperatures, and the frequency of the compressor in the air conditioner.

[0049] The air supply device includes a cross-flow fan and multiple air supply fans; the air conditioner includes multiple air outlets, and each air outlet is equipped with an air supply fan, which can rotate around the inner diameter of the corresponding air outlet.

[0050] It should be noted that the execution subject of this embodiment of the invention is the control device of an air conditioner.

[0051] It should be noted that the air conditioner in this embodiment of the invention can be used to regulate the indoor ambient temperature.

[0052] Outdoor ambient temperature refers to the ambient temperature outside the room within a preset distance from the room. For example, the outdoor ambient temperature can be the ambient temperature outside the room 10 meters away from the room.

[0053] It should be noted that the air conditioner control method provided by this invention is applied to air conditioners with multiple air outlets. The air supply device in the air conditioner includes a cross-flow fan and multiple supplementary air fans. Each air outlet is provided with a supplementary air fan, which can rotate around the inner diameter of the corresponding air outlet, and can also rotate relative to a 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.

[0054] 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.

[0055] 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.

[0056] Figure 2 This is one of the perspective views of the air conditioner in the air conditioner control method provided by the present invention. Figure 3 This is a front view of the air conditioner in the air conditioner control method provided by the present invention. Figure 4 This is a cross-sectional view of the air conditioner in the air conditioner control method provided by the present invention. Figure 2 , Figure 3 and Figure 4 As shown, the air supply device in the air conditioner includes a cross-flow fan 401 and a first number of supplementary air fans 201.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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 away from the housing 203.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] A cross-flow fan 401 is located below the evaporator 402. The blades of the cross-flow fan 401 can rotate clockwise or counterclockwise.

[0068] 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.

[0069] The movable baffle 206 can be driven by a second stepper motor 208 located near the air inlet 205.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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; the frequency of the compressor can also be obtained based on the controller of the air conditioner.

[0076] 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.

[0077] In this embodiment of the invention, when the air conditioner is turned on, the temperature difference between the indoor and outdoor environments can be obtained in various ways. For example, a temperature difference sensor can be used to obtain the indoor and outdoor temperatures respectively, and the temperature difference between the indoor and outdoor environments can be obtained through numerical calculation.

[0078] It is understandable that indoor and outdoor ambient temperatures are dynamic, and correspondingly, the temperature difference between indoor and outdoor ambient temperatures is also dynamic.

[0079] Step 102: Based on the operating mode and temperature difference, as well as the frequency or preset speed, control the air supply device in the air conditioner.

[0080] Specifically, after obtaining the operating mode of the air conditioner and the temperature difference between the indoor and outdoor environments, a condition judgment can be made based on the operating mode of the air conditioner and the aforementioned temperature difference. Based on the result of the condition judgment and the frequency or preset speed of the compressor, one or more of the following can be controlled: the fan speed of the supplementary air fan 201 in the aforementioned air supply device; the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204; the fan blade rotation mode of the cross-flow fan 401 and the supplementary air fan 201; and the direction of the gas blown out or drawn in by the supplementary air fan.

[0081] 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.

[0082] It is understandable that by controlling the direction of the air blowing out or drawing in by the air supply fan 201, the air outlet 204 can independently blow out or draw in air in all directions, up, down, left, and right.

[0083] 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.

[0084] 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.

[0085] This invention controls the air supply device in the air conditioner based on the air conditioner's operating mode, the temperature difference between indoor and outdoor environments, and the compressor's frequency and preset speed. 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. It allows for more flexible control of the air supply device in the air conditioner according to actual conditions, thereby improving the air conditioner's heat exchange efficiency and capacity, enhancing user experience, and reducing the air conditioner's energy consumption.

[0086] Based on the above embodiments, based on the operating mode and temperature difference, as well as frequency or preset speed, the air supply device in the air conditioner is controlled, including: when the operating mode of the air conditioner is cooling mode or heating mode, controlling the blades of the cross-flow fan 401 and the blades of the supplementary air fan 201 to rotate clockwise, controlling the speed of the blades of the cross-flow fan 401 to execute a preset speed, and determining the preset range of the temperature difference.

[0087] Among them, the first preset interval, the second preset interval, and the third preset interval are connected and increase sequentially; the first target speed, the third target speed, and the fifth target speed are determined based on the preset speed, and the first target speed, the third target speed, and the fifth target speed decrease sequentially; the second target speed, the fourth target speed, and the sixth target speed are determined based on the frequency, and the second target speed, the fourth target speed, and the sixth target speed decrease sequentially.

[0088] Specifically, when the air conditioner is in cooling mode, the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate clockwise, thereby controlling the cross-flow fan 401 and the air supply fan 201 to blow out gas.

[0089] When the air conditioner is in cooling or heating mode, the cross-flow fan 401 can also be controlled to execute a preset speed H0.

[0090] It should be noted that, in the embodiments of the present invention, the first target speed H1, the third target speed H3 and the third target speed H5 can be determined by numerical calculation based on a preset speed H0, and the second target speed H2, the fourth target speed H4 and the sixth target speed H6 can be determined by numerical calculation based on the compressor frequency H.

[0091] 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.

[0092] Preferably, the first preset value x1 can be 1 / 2, that is, H1 = H0 × 1 / 2.

[0093] 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.

[0094] Preferably, the third preset value x3 can be 1 / 3, that is, H3 = H0 × 1 / 3.

[0095] 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.

[0096] Preferably, the fifth preset value x5 can be 1 / 4, that is, H5 = H0 × 1 / 4.

[0097] 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.

[0098] Preferably, the second preset value x2 can be 2, that is, H2 = H × 2.

[0099] 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.

[0100] Preferably, the fourth preset value x4 can be 1, that is, H4 = H.

[0101] 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.

[0102] Preferably, the sixth preset value x6 can be 2, i.e., H2 = H × 1 / 2.

[0103] When the temperature difference is within the first preset range, the fan speed of the supplementary air fan 201 is controlled to achieve the first 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 achieve the second target speed.

[0104] Specifically, based on the preset range of the temperature difference between the outdoor and indoor environments, it can be determined whether the temperature difference is large, moderate, or small. A large temperature difference indicates that the indoor temperature has met the user's needs, and the user's temperature adjustment requirements for the air conditioner are low. A moderate temperature difference indicates that the indoor temperature is close to the user's needs, and the user's temperature adjustment requirements for the air conditioner are moderate. A small temperature difference indicates that the indoor temperature is far from meeting the user's needs, and the user's temperature adjustment requirements for the air conditioner are high.

[0105] It should be noted that the first preset interval, the second preset interval, and the third preset interval can be determined based on prior knowledge. In this embodiment of the invention, the first preset interval, the second preset interval, and the third preset interval are not specifically limited.

[0106] Optionally, the first preset interval can be (-∞, 5], the second preset interval can be (5, 15], and the third preset interval can be (15, +∞).

[0107] When the air conditioner is in cooling mode and ΔT∈[0,5], it means that the temperature difference between the outdoor and indoor environments is small. The fan speed of the supplementary air fan 201 can be controlled to achieve the first target speed H1, so that the air conditioner delivers cold air at a higher wind speed. The speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can be controlled to achieve the second target speed H2, so that the indoor air flow speed is faster. Thus, when the temperature difference is in the first preset range, the cooling capacity of the air conditioner can be maximized, and the indoor temperature can be cooled down the fastest.

[0108] When the air conditioner is in heating mode and ΔT∈[0,5], it indicates that the temperature difference between the outdoor and indoor environments is small. The fan speed of the supplementary air fan 201 can be controlled to achieve the first target speed H1, so that the air conditioner delivers hot air at a higher wind speed. The speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can also be controlled to achieve the second target speed H2, so that the indoor air flow speed is faster. Thus, when the temperature difference is within the first preset range, the heating capacity of the air conditioner can be maximized, and the indoor temperature can be raised at the fastest rate.

[0109] When the temperature difference is in the second preset 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.

[0110] Specifically, when the air conditioner is in cooling mode and ΔT∈(5,15], it indicates that the temperature difference between the outdoor and indoor environments is moderate. The fan speed of the supplementary air fan 201 can be controlled to achieve the third target speed H3, so that the air conditioner delivers cold air at a moderate wind speed. The speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can also be controlled to achieve the fourth target speed H4, so that the indoor air flow speed is moderate. Thus, when the temperature difference is in the second preset range, the cooling capacity of the air conditioner can be controlled to be moderate, and the cooling rate of the indoor environment can be moderate.

[0111] When the air conditioner is in heating mode and ΔT∈(5,15], it indicates that the temperature difference between the outdoor and indoor environments is moderate. The fan speed of the supplementary air fan 201 can be controlled to achieve the third target speed H3, so that the air conditioner delivers hot air at a moderate wind speed. The speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can also be controlled to achieve the fourth target speed H4, so that the indoor air flow speed is moderate. Thus, when the temperature difference is in the second preset range, the heating capacity of the air conditioner can be controlled to be moderate, and the rate of temperature rise in the indoor environment can be moderate.

[0112] When the temperature difference is within the third preset 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.

[0113] Specifically, when the air conditioner is in cooling mode and ΔT∈(15,+∞), it indicates that the temperature difference between the outdoor and indoor environments is large. The fan speed of the supplementary air fan 201 can be controlled to achieve the fifth target speed H5, so that the air conditioner delivers cold air at a lower speed. The speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can also be controlled to achieve the sixth target speed H6, so that the indoor air flow speed is slower. Thus, when the temperature difference is within the second preset range, the cooling capacity of the air conditioner can be minimized to maintain the indoor environment temperature.

[0114] When the air conditioner is in heating mode and ΔT∈(15,+∞), it indicates that the temperature difference between the outdoor and indoor environments is large. The fan speed of the supplementary air fan 201 can be controlled to achieve the fifth target speed H5, so that the air conditioner delivers hot air at a lower speed. The speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can also be controlled to achieve the sixth target speed H6, so that the indoor air flow speed is slower. Thus, when the temperature difference is within the second preset range, the heating capacity of the air conditioner can be minimized, thereby maintaining the indoor ambient temperature.

[0115] This invention, when the air conditioner is in cooling or heating mode, controls the blades of the cross-flow fan and the air supply fan to rotate clockwise. The rotation speed of the cross-flow fan blades is controlled to a preset speed. Based on a preset range of temperature difference between indoor and outdoor environments, and a preset speed or compressor frequency, the air supply fan blade speed and the rotation speed of the air supply fan around the inner diameter of the corresponding air outlet are more flexibly controlled. This allows for more flexible control of the airflow speed in cooling or heating mode based on actual conditions, improving the air conditioner's heat exchange efficiency and capacity, and reducing its energy consumption.

[0116] Based on the above embodiments, based on the operating mode and temperature difference, and frequency or preset speed, the air supply device in the air conditioner is controlled, including: when the air conditioner is in the air supply mode, controlling the blades of the cross-flow fan 401 and the air supply fan 201 to rotate clockwise, controlling the speed of the blades of the cross-flow fan 401 to execute a preset speed, controlling the angle between the direction of the air blown out by the air supply fan 201 and the vertical downward direction to be less than 90°, and determining the preset range of the temperature difference.

[0117] Specifically, when the air conditioner is in the air supply mode, the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate clockwise, thereby controlling the cross-flow fan 401 and the air supply fan 201 to blow out air.

[0118] When the air conditioner is in the air supply mode, the cross-flow fan 401 can also be controlled to execute the preset speed H0.

[0119] It should be noted that, in this embodiment of the invention, the angle between the central axis of the projection of the supplementary air fan 201 onto the plane where the air outlet 204 is located and the central axis of the air outlet 204 in the vertically upward direction, in the clockwise direction, can be taken as the rotation angle of the supplementary air fan 201 relative to the first rotation axis. The central axis of the projection of the supplementary air fan 201 onto the plane where the air outlet 204 is located passes through the center point of the air outlet 204.

[0120] Figure 5 This is the second perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. When the rotation angle of the air supply fan 201 relative to the first rotation axis is 0° or 360°, the perspective view of the air conditioner is as follows. Figure 5 As shown.

[0121] 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. With the air supply fan 201 rotating at a 90° angle relative to the first rotation axis, the perspective view of the air conditioner is as follows. Figure 6 As shown.

[0122] Figure 7 This is the fourth perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating at an angle of 180° relative to the first rotation axis, the perspective view of the air conditioner is as follows. Figure 7 As shown.

[0123] Figure 8 This is the fifth perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating at an angle of 270° relative to the first rotation axis, the perspective view of the air conditioner is as follows. Figure 8 As shown.

[0124] like Figures 5 to 8As 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.

[0125] In order to improve the long-distance air delivery capability of the air conditioner in the air supply mode, when the air conditioner is in the cooling mode, the rotation angle of the air supply fan 201 relative to the first rotation axis can be controlled within (90°, 270°). That is, the angle between the direction of the air supply fan 201 blowing out gas and the vertical downward direction can be controlled to be less than 90°. This allows the air conditioner to deliver air downward to the reference horizontal plane in the air supply mode, which can increase the air blowing distance of the air conditioner in the air supply mode, thereby further increasing the airflow of the indoor air.

[0126] When the temperature difference is within the first preset range, the fan speed of the supplementary air fan 201 is controlled to achieve the first 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 achieve the second target speed.

[0127] Specifically, when ΔT∈[0,5], it indicates that the temperature difference between the outdoor and indoor environments is small. The fan speed of the supplementary air fan 201 can be controlled to achieve the first target speed H1, and the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can be controlled to achieve the second target speed H2, so that the air conditioner delivers air at a higher wind speed to the lower part of the reference horizontal plane, and the indoor air flow speed is faster.

[0128] When the temperature difference is in the second or third preset range, the fan speed of the air supply fan 201 is controlled to execute the first target speed, and the speed at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet is controlled to execute the fourth target speed.

[0129] Specifically, when ΔT∈(5,+∞), it indicates that the temperature difference between the outdoor and indoor environments is moderate or large. The fan speed of the supplementary air fan 201 can be controlled to achieve the first target speed H1, and the speed at which the supplementary air fan 201 rotates around the inner diameter of the corresponding air outlet 204 can be controlled to achieve the fourth target speed H4, so that the air conditioner delivers air at a higher wind speed to the lower part of the reference horizontal plane, and the indoor air flow speed is moderate.

[0130] This invention, when the air conditioner is in ventilation mode, controls the blades of the cross-flow fan and the air supply fan to rotate clockwise, controls 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°, controls the speed of the cross-flow fan blades to execute a preset speed, and, based on a preset range of temperature difference between the indoor and outdoor environments, provides more flexible control over the speed of the air supply fan blades and the speed at which they rotate around the inner diameter of the corresponding air outlet. This allows for more flexible control over the airflow speed of the air conditioner in ventilation mode based on actual conditions, increasing the airflow distance in ventilation mode, thereby further increasing indoor air circulation and reducing the energy consumption of the air conditioner.

[0131] Based on the above embodiments, based on the operating mode and temperature difference, as well as frequency or preset speed, the air supply device in the air conditioner is controlled, including: when the operating mode of the air conditioner is cooling mode or heating mode, and the temperature difference is within a fourth preset range, the air supply fan 201 is controlled to rotate clockwise around the inner diameter of the corresponding air outlet 204.

[0132] It should be noted that the fourth preset interval can be determined based on prior knowledge. In this embodiment of the invention, the fourth preset interval is not specifically limited.

[0133] Optionally, the fourth preset interval can be (10, +∞).

[0134] Specifically, when the air conditioner is in cooling or heating mode and ΔT∈(10,+∞), it indicates that the indoor ambient temperature has not yet met the user's needs. In order to improve the temperature regulation effect of the air conditioner, the air supply fan 201 can be controlled to rotate clockwise around the inner diameter of the corresponding air outlet 204.

[0135] This invention, when the air conditioner is in cooling or heating mode and the temperature difference between the indoor and outdoor environments is within a fourth preset range, controls the air supply fan to rotate clockwise around the inner diameter of the corresponding air outlet. This allows for more flexible control of the air supply fan's rotation around the inner diameter of the corresponding air outlet, thereby improving the air conditioner's heat exchange efficiency and capacity, and reducing its energy consumption.

[0136] Based on the above embodiments, and based on the operating mode, temperature difference, frequency, or preset speed, the air supply device in the air conditioner is controlled, including: when the air conditioner is in the target operating mode, controlling the blades of the cross-flow fan 401 and the air supply fan 201 to rotate counterclockwise, controlling the speed of the blades of the cross-flow fan 401 to execute a preset speed, controlling the angle between the direction of the air supply fan 201 drawing in gas and the vertical upward direction to be less than 90°, and controlling the speed of the blades of the air supply fan 201 to execute a third target speed.

[0137] The target modes include: defrosting mode or self-cleaning mode.

[0138] Specifically, in order not to affect the performance of the air conditioner in the target mode and to reduce the noise of the air conditioner, when the air conditioner is in the target mode and the temperature difference is arbitrary, the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled to rotate counterclockwise. This allows the cross-flow fan 401 and the air supply fan 201 to draw in air. The blade speed of the cross-flow fan 401 can be controlled to execute a preset speed, and the blade speed of the air supply fan 201 can be controlled to execute a third target speed. This allows the air conditioner to draw in air from above the reference horizontal plane at a medium fan speed.

[0139] 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 angle between the direction of the gas drawn in by the cross-flow fan 401 and the vertical upward direction can be controlled to be less than 90°, and the rotation angle of the supplementary air 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 gas drawn in by the supplementary air fan 201 and the vertical upward direction can be controlled to be less than 90°, so that the air conditioner can draw in gas from above the reference horizontal plane in the target mode.

[0140] It should be noted that when the air conditioner is in target mode, the speed at which the air supply fan 201 rotates around the inner diameter of the corresponding air outlet 204 is zero.

[0141] In this embodiment of the invention, when the air conditioner is in the target operating mode, the blades of the cross-flow fan and the air supply fan are controlled to rotate counterclockwise, the angle between the direction of the air supply fan drawing in the gas and the vertical upward direction is controlled to be less than 90°, the speed of the air supply fan blades is controlled to execute the third target speed, and the speed of the cross-flow fan blades is controlled to execute the preset speed. This allows the air conditioner to draw in gas from above the reference horizontal plane, avoiding affecting the performance of the air conditioner in the target mode and reducing the noise of the air conditioner.

[0142] Based on the above embodiments, the rotation of each supplementary air fan 201 around the inner diameter of each air outlet 204 is synchronized.

[0143] Optionally, in this embodiment of the invention, the rotation of each supplementary air fan 201 relative to each first rotation axis can be synchronized.

[0144] In this embodiment of the invention, each supplementary air fan rotates synchronously around the inner diameter of each air outlet, which can avoid the air supply area of ​​the air conditioner being dispersed or concentrated. Without increasing the feeling of being blown by the air, it can further increase the air outlet range and the air blowing distance of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the user experience.

The speed of the movement is set to the fourth target speed; when the temperature difference is within the third preset range, the speed of the air supply fan blades is set to the fifth target speed, and the speed of the air supply fan rotating around the inner diameter of the corresponding air outlet is set to the sixth target speed; wherein, the first preset range, the second preset range, and the third preset range are connected and increase sequentially; the first target speed, the third target speed, and the fifth target speed are determined based on the preset speed, and the first target speed, the third target speed, and the fifth target speed decrease sequentially; the second target speed, the fourth target speed, and the sixth target speed are determined based on the frequency, and the second target speed, the fourth target speed, and the sixth target speed decrease sequentially.
