Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a control method and device for an air conditioner, an air conditioner, and a storage medium. Background Art

[0002] At present, the air outlet mode of the indoor unit of the air conditioner basically adopts a single air outlet position, which can only be upward or downward. With this air outlet mode, the air outlet direction is generally the same whether in cooling or heating mode. If the conventional downward air outlet mode is used, the cold air will blow directly at people at a certain angle. In addition, theoretically, the density of cold air is greater than that of hot air, so it is more suitable for the upward air outlet mode; and when the temperature of the feet is higher than that of the head, the comfort of the person is better, so hot air is more suitable for the downward air outlet mode.

[0003] In order to improve the comfort of air supply, the related art discloses an indoor air conditioner, which includes an air conditioner body and an air supply mixing assembly. The air conditioner body also includes an air guide plate, which is installed at the main air supply port, and the horizontal plane of the air guide plate is perpendicular to the plane where the main air supply port is located. The flow direction of the air sent from the main air supply port to the room is parallel to the horizontal plane of the air guide plate, so that at least part of the air sent from the main air supply port can enter the mixed flow through flow assembly, and the air after heat exchange is mixed with the indoor air that has not been heat exchanged and then sent to the room again.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, strong cooling or heating air is formed at the main air outlet, and comfortable cooling or heating air is formed at the mixed flow outlet of the air supply mixing component, forming a layered air supply mode. Therefore, the degree of mixing of the cooling or heating air blown out of the main air outlet with the indoor air is low, and the comfort still cannot meet the requirements.

[0064] Combination Figure 2 The processor 200 of the air conditioner is used to receive and send information and instructions.

[0065] In order to improve the comfort of air supply, the air conditioner includes a heat exchange housing, which is provided with a heat exchange outlet; a wind uniforming arm, which is provided with a wind uniforming component facing the heat exchange outlet, and the wind uniforming component is used to introduce the indoor wind into the heat exchange outlet, and mix it with the wind at the heat exchange outlet before blowing it out. This solution is applied to the air conditioner with the above-mentioned wind uniforming arm, and the structure is used to improve the comfort of air supply. The driving device 210 and the wind uniforming component 220 of the wind uniforming arm are respectively connected to the processor 200.

[0066] Furthermore, in order to realize the air conditioning function of the air conditioner, some air conditioners are also equipped with a temperature sensor for obtaining the indoor ambient temperature.

This solution is applied to the above-mentioned air conditioner equipped with a temperature sensor, and the indoor ambient temperature is determined by using it.

[0067] The processor 200 is used to receive data information sent by the cloud server, and output control signals to the driving device 210 and the wind uniforming component 220 of the wind uniforming arm according to the detection results of the temperature sensor.

[0068] Figure 3 , 4 It is an overall schematic diagram of the air conditioner provided by the embodiment of the present disclosure.

[0069] Combination Figure 3 , 4 As shown, an embodiment of the present disclosure provides an air conditioner, which includes an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected by a connecting pipe to realize the circulation of refrigerant between the indoor unit and the outdoor unit.

[0070] The indoor unit includes a heat exchange body 1 and an air uniforming arm 2.

[0071] The heat exchange body 1 includes a heat exchange shell 11 and a heat exchanger 15 disposed in the heat exchange shell 11. The heat exchange shell 11 is provided with a heat exchange air outlet 12 for blowing out heat exchange air. Specifically, the heat exchange body 1 also includes a fan, and the heat exchange shell 11 is also provided with a heat exchange air inlet. Driven by the fan, air enters from the heat exchange air inlet, and forms heat exchange air after heat exchange with the heat exchanger 15. The heat exchange air is blown out from the heat exchange air outlet 12.

[0072] The wind uniforming arm 2 is arranged on the outside of the heat exchange shell 11 and is located at the heat exchange air outlet 12. Here, it can be understood that the wind uniforming arm 2 is arranged near the heat exchange air outlet 12 and is at a small distance from the heat exchange air outlet 12. The wind uniforming arm 2 includes a wind uniforming shell 21 and a wind uniforming component 22 arranged in the wind uniforming shell 21. The wind uniforming shell 21 is provided with a wind uniforming inlet 213 and a wind uniforming outlet 214. The wind uniforming component 22 is used to introduce indoor air into the heat exchange air outlet 12, and mix it with the wind at the heat exchange air outlet 12 and then blow it out.

[0073] Alternatively, if Figure 3 As shown, the heat exchange housing 11 includes an upper air outlet edge 121 and a lower air outlet edge 122 forming a heat exchange air outlet 12 .

[0074] The wind uniforming arm 2 is disposed at the upper portion of the upper wind outlet edge 121 ; or, the wind uniforming arm 2 is disposed at the lower portion of the lower wind outlet edge 122 .

[0075] Driven by the wind uniforming member 22, the indoor induced air is mixed with the heat exchange air blown out of the heat exchange air outlet 12, thereby improving the air supply comfort of the indoor unit. In the heating mode, a comfortable wind is formed, which is warm but not dry. In particular, in the cooling mode, a comfortable and soft wind is formed, which is cool but not cold, and the landing time of the cold air blown out of the heat exchange air outlet 12 can be delayed to prevent the cold wind from blowing directly.

[0076] Optionally, the heat exchange shell 11 includes a heat exchange bottom shell 13 , and the heat exchange air outlet 12 is located at the front side of the heat exchange bottom shell 13 ; wherein the air uniforming arm 2 is disposed on the heat exchange bottom shell 13 .

[0077] In this solution, the uniform wind arm 2 is arranged at the rear side of the heat exchange outlet 12, so that the indoor induced air blown out by the uniform wind outlet 214 blows forward toward the heat exchange outlet 12, thereby driving the heat exchange air to blow forward as a whole without affecting the wind direction of the indoor unit's forward air outlet.

[0078] Optionally, the wind uniforming arm 2 is disposed at a lower portion of the heat exchange air outlet 12 , that is, the wind uniforming arm 2 is lower than the heat exchange air outlet 12 .

[0079] The uniform air outlet 214 faces the heat exchange air outlet 12, and the indoor induced air blown out by the uniform air outlet 214 blows upward toward the heat exchange air outlet 12, thereby delaying the time for cold air to fall to the ground in the cooling mode and preventing cold air from blowing directly, while increasing the cold air supply distance to achieve uniform indoor temperature.

[0080] like Figure 3 As shown, the wind uniforming arm 2 is arranged below the heat exchange bottom shell 13.

[0081] In this solution, the indoor induced air blown out from the uniform air outlet 214 is blown upward to the heat exchange air outlet 12, thereby delaying the time for the cold air to fall to the ground.

[0082] Optionally, the air conditioner indoor unit further includes a connecting arm, which connects the wind uniforming arm 2 and the heat exchange shell 11 to achieve connection between the wind uniforming arm 2 and the heat exchange shell 11.

[0083] In some embodiments, the heat exchange shell 11 includes a heat exchange bottom shell 13, and a passive air induced distance is set between the air outlet top of the uniform air outlet 214 and the heat exchange bottom shell 13, so that the indoor air at the rear of the uniform air arm 2 is mixed with the heat exchange air through the passive air induced distance.

[0084] Specifically, an air guide plate is provided at the heat exchange air outlet 12 of the air conditioner indoor unit. When the air conditioner indoor unit is in operation, when the angle between the air guide plate and the horizontal plane is 30°, the air volume of the heat exchange air is 693m 3 / h, at this time the active uniform air volume is 87m 3 / h, passive uniform air volume is 5.4m 3 / h, and the heat exchange air flow, active uniform air flow and passive uniform air flow are relatively stable and mixed evenly. When the angle between the air guide plate and the horizontal plane is 10°, the air volume of the heat exchange air is 486m 3 / h, at this time the active uniform air volume is 88m 3 / h, and the passive uniform air volume is 5.3m3 / h. By comparing the airflows under different angles between the air guide plate and the horizontal plane, it can be seen that the different angles between the air guide plate and the horizontal plane will affect the air volume of the heat exchange air, but will not affect the air volume of the active and passive uniform air. Furthermore, the active and passive uniform air can reduce the backflow vortex under the air guide plate.

[0085] Alternatively, if Figure 4 In the initial position, the angle A between the wind uniforming upper surface 211 of the wind uniforming housing 21 and the horizontal plane is greater than or equal to 10°.

[0086] By setting the angle between the uniform wind upper surface 211 and the horizontal plane to be greater than or equal to 10°, the uniform wind outlet 214 can be directed toward the heat exchange outlet 12, thereby allowing the wind blown out from the uniform wind outlet 214 to be more effectively mixed with the heat exchange air.

[0087] Optionally, the wind uniforming member 22 comprises an axial flow fan, wherein the wind outlet direction of the axial flow fan is perpendicular to the wind uniforming upper surface 211 of the wind uniforming housing 21 .

[0088] With such a configuration, when the axial flow fan rotates forward in the first mode, indoor air can be introduced from the uniform wind lower surface 212 and blown out from the uniform wind upper surface 211. At this time, the actual air outlet of the uniform wind arm is the uniform wind outlet 214, which can make the indoor induced air blown out from the actual air outlet of the uniform wind arm blow toward the heat exchange outlet 12 to achieve mixing with the heat exchange air. When the axial flow fan rotates in the second mode in the reverse direction, the air at the heat exchange outlet can be sucked in from the uniform wind upper surface 211 of the uniform wind arm and sent out from the uniform wind lower surface 212 of the uniform wind arm. At this time, the actual air outlet of the uniform wind arm is the uniform wind inlet 213. The air supply distance can be increased.

[0089] Optionally, the uniform air outlet 214 of the uniform air arm 2 is tilted toward the heat exchange outlet 12 .

[0090] Such an arrangement allows the indoor induced air blown out from the uniform air outlet 214 of the uniform air arm 2 to flow directly to the heat exchange air outlet 12 to mix with the heat exchange air, thereby reducing the wind resistance caused when the indoor induced air passes through the uniform air outlet 214, increasing the degree of mixing of the indoor induced air and the heat exchange air, and achieving a better uniform air effect.

[0091] Optionally, the wind uniforming housing 21 includes a wind uniforming upper surface 211 and a wind uniforming lower surface 212 that are arranged opposite to each other, the wind uniforming inlet 213 is arranged on the wind uniforming lower surface 212, and the wind uniforming outlet 214 is arranged on the wind uniforming upper surface 211.

[0092] Optionally, the wind uniforming member 22 includes a plurality of axial flow fans. In other embodiments, it may also include one or more of a centrifugal fan, a cross-flow fan, etc.

[0093] Optionally, the uniform wind upper surface 211 is tilted downward from the back to the front, so that the uniform wind outlet 214 arranged on the uniform wind upper surface 211 is tilted toward the heat exchange outlet 12 .

[0094] Optionally, the angle between the uniform wind upper surface 211 and the horizontal plane ranges from 5° to 45°.

[0095] When the angle between the uniform wind upper surface 211 and the horizontal plane is less than 5°, the inclination of the uniform wind upper surface 211 is low, and the contact area between the indoor induced air blown out from the uniform wind outlet 214 and the heat exchange air is small, which affects the degree of mixing between the two; when the angle between the uniform wind upper surface 211 and the horizontal plane is greater than 45°, when the wind speed of the indoor induced air is constant, the upward component of the wind speed of the indoor induced air blown out from the uniform wind outlet 214 is small, and the lifting effect on the heat exchange air will be reduced.

[0096] The control method thereof will be described below in conjunction with the above-mentioned air conditioner.

[0097] Figure 5This is a flow chart of a control method for an air conditioner provided in an embodiment of the present disclosure, which is applied to the above-mentioned air conditioner with a uniform wind arm. The control method for an air conditioner can be executed by a processor of the air conditioner, or in a server, such as a cloud server communicating with the air conditioner; or in a terminal device, such as a smart phone, a control terminal of a smart home appliance, etc. In the embodiment of the present disclosure, the processor of the air conditioner is used as the execution subject to illustrate the scheme.

[0098] The control method for air conditioning comprises:

[0099] Step S501: the processor detects the indoor ambient temperature and obtains the temperature difference between the indoor ambient temperature and the set temperature.

[0100] Step S502: The processor determines the operation strategy of the uniform air arm according to the interval in which the temperature difference exists.

[0101] Step S503: the processor controls the air uniforming components of the air uniforming arm according to the operation strategy to achieve different air supply modes.

[0102] The temperature difference between the indoor environment temperature and the set temperature is used to reflect the current air conditioning intensity of regulating the indoor environment. The larger the value of the temperature difference, the stronger the air conditioning intensity of regulating the indoor environment.

[0103] The operation strategy of the wind uniforming arm refers to adjusting the intensity of the indoor wind introduced to the heat exchange outlet by controlling the operation parameters of the wind uniforming arm. Optionally, it includes adjusting one or more of the wind volume, wind speed and wind direction.

[0104] The air supply mode refers to the way in which the indoor air introduced to the heat exchange outlet is mixed with the air at the heat exchange outlet and then delivered. In this way, by controlling the air distribution component of the air distribution arm to operate according to the operation strategy, an air supply mode adapted to the temperature difference can be achieved.

[0105] The disclosed embodiment is based on an air conditioning structure in which a uniform wind arm is arranged at the heat exchange air outlet of the air conditioner, so as to guide the indoor wind to the air outlet, and then blow it out after mixing with the wind at the air outlet. In addition, the operation strategy of the uniform wind arm is adjusted according to the temperature difference between the indoor ambient temperature and the set temperature, so that the position of the uniform wind arm and the operation parameters of the uniform wind component in the uniform wind arm can be adapted to the current indoor temperature difference, so as to adjust the air supply direction and air supply distance of the mixed air at the air outlet of the air conditioner, thereby improving the uniformity of the indoor temperature and the comfort of air supply.

[0106] Optionally, according to the interval in which the temperature difference is located, an operation strategy of the uniform air arm is determined, including:

[0107] Obtain the corresponding relationship between the difference interval and the operation strategy of the uniform wind arm;

[0108] The corresponding operation strategy is determined according to the difference interval in which the temperature difference lies; the operation strategy includes the position information of the wind uniformity arm and / or the operation information of the wind uniformity component.

[0109] The correspondence between the difference interval and the operation strategy of the uniform wind arm can be in the form of a one-to-one correspondence data table. In this case, the correspondence between the difference interval and the operation strategy of the uniform wind arm can be stored in a database in advance. After obtaining the current temperature difference, the operation strategy of the uniform wind arm corresponding to the difference interval where the current temperature difference is located can be obtained by querying the database.

[0110] The position information of the air uniforming arm includes the position information of the air uniforming arm relative to the heat exchange outlet of the air conditioner.

[0111] The operation information of the wind uniforming component refers to the parameter information of the wind uniforming component, including the rotation speed and direction of the wind uniforming component, which corresponds to the wind volume and wind direction introduced into the room.

[0112] Here, by determining the operation strategy related to the position information of the wind uniforming arm and / or the operation information of the wind uniforming component, an air supply mode adapted to the temperature difference can be achieved.

[0113] Further, in the case where the operation strategy includes the position information of the wind uniformity arm, the determination of the operation strategy includes:

[0114] When the temperature difference is greater than or equal to the first threshold, the target operating position of the wind uniformity arm is the first position;

[0115] When the temperature difference is less than the first threshold, the target operating position of the wind uniformity arm is the second position;

[0116] The regulation intensity of the wind at the heat exchange outlet at the first position is lower than the regulation intensity of the wind at the heat exchange outlet at the second position.

[0117] The intensity of regulating the wind at the heat exchange outlet refers to the degree of change of the wind at the heat exchange outlet through the wind uniformity arm. For example, under the same air volume, the regulation intensity of increasing the air supply distance is higher than that of not increasing the air supply distance; under the same air supply distance, the regulation intensity of increasing the air volume (such as increasing the mixed air volume through the wind uniformity arm) is higher than that of not increasing the air volume.

[0118] Figure 6a , 6b Schematic diagrams showing two positions of the wind uniforming arm.

[0119] in, Figure 6a The position of the wind uniformity arm shown is the first position. When the wind uniformity arm is in the first position, the wind uniformity volume can be increased, so that the overall air supply of the air conditioner is comfortable and soft, cool but not cold; and the cold wind is delayed from falling to the ground to prevent the cold wind from blowing on people.

[0120] Figure 6b The position of the uniform wind arm shown is the second position. When the uniform wind arm is in the second position, the air supply distance can be increased while the uniform wind volume is increased, thereby accelerating the uniformity of indoor temperature.

[0121] Under the same air volume condition, the air supply distance when the wind uniforming arm is in the first position is smaller than the air supply distance when the wind uniforming arm is in the second position. Therefore, the regulation intensity of the wind at the heat exchange outlet in the first position is lower than the regulation intensity of the wind at the heat exchange outlet in the second position.

[0122] Optionally, the angle between the upper surface of the uniform wind arm and the plane where the lower air outlet edge of the heat exchange outlet of the air conditioner is located in the first position is in the range of [10°, 55°]. It can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°. In the embodiment of the present disclosure, the angle is set to 35°. Moreover, when the uniform wind arm is in the first position, the distance between its upper surface and the lower air outlet edge of the heat exchange outlet of the air conditioner is less than the distance between its upper surface and the upper air outlet edge of the heat exchange outlet of the air conditioner.

[0123] Optionally, the second position is that the angle between the upper surface of the wind uniforming arm and the plane where the lower air outlet edge of the heat exchange outlet of the air conditioner is located is in the range of [-10°, -60°], wherein the direction of the angle formed by rotating clockwise along the plane where the lower air outlet edge is located is set to the positive direction, and the direction of the angle formed by rotating counterclockwise along the plane where the lower air outlet edge is located is set to the negative direction. It can be -15°, -20°, -25°, -30°, -35°, -40°, -45°, -50°, -55°. In the embodiment of the present disclosure, the angle is set to -30°. Moreover, when the wind uniforming arm is in the second position, the distance between its upper surface and the lower air outlet edge of the heat exchange outlet of the air conditioner is greater than the distance between its upper surface and the upper air outlet edge of the heat exchange outlet of the air conditioner.

[0124] When the temperature difference is greater than or equal to the first threshold, the air conditioning temperature adjustment demand is large, and the temperature difference between the air delivered from the indoor unit and the indoor ambient temperature is large. By setting the target operating position of the uniform air arm to the first position, the uniform air volume can be increased while making the overall air supply of the air conditioner comfortable and soft.

[0125] When the temperature difference is less than the first threshold, the demand for air conditioning temperature adjustment is relatively reduced, and the temperature difference between the air delivered from the indoor unit and the indoor environment is relatively reduced. By setting the target operating position of the air uniforming arm to the second position, the air supply distance can be increased, thereby assisting in achieving long-distance air supply.

[0126] Optionally, the first threshold is 2°C.

[0127] Furthermore, when the air conditioner operates in cooling mode, the determination of the operation strategy also includes:

[0128] When the temperature difference is greater than or equal to the first threshold value and less than or equal to the second threshold value, the air uniformity component operates in the first mode, sucking in indoor air from the air uniformity lower surface of the air uniformity arm and blowing it to the heat exchange outlet from the air uniformity upper surface of the air uniformity arm;

[0129] When the temperature difference is greater than the second threshold, the wind uniformity component is closed;

[0130] When the temperature difference is less than the first threshold, the wind uniforming component operates in the second mode, sucking air at the heat exchange outlet from the wind uniforming upper surface of the wind uniforming arm and sending it out from the wind uniforming lower surface of the wind uniforming arm.

[0131] Here, the wind direction of the introduced wind is adjusted by controlling the operating information of the wind uniforming component.

[0132] As can be seen from the above description of the wind uniforming component, the wind uniforming component includes an axial flow fan. When the axial flow fan rotates in the first mode in the forward direction, its air outlet direction is perpendicular to the wind uniforming upper surface of the wind uniforming arm; it is possible to introduce indoor air from the wind uniforming lower surface and blow it out from the wind uniforming upper surface. At this time, the actual air outlet of the wind uniforming arm is the wind uniforming outlet. When the axial flow fan rotates in the second mode in the reverse direction, its air outlet direction is perpendicular to the wind uniforming lower surface of the wind uniforming arm; it is possible to inhale the wind at the heat exchange outlet from the wind uniforming upper surface of the wind uniforming arm and send it out from the wind uniforming lower surface of the wind uniforming arm. At this time, the actual air outlet of the wind uniforming arm is the wind uniforming inlet.

[0133] In this way, when the temperature difference is greater than or equal to the first threshold and less than or equal to the second threshold, the air conditioner operates in the comfort air supply mode, controls the wind uniforming arm to be in the first position, and the wind uniforming component operates in the first mode to introduce the indoor air into the heat exchange outlet and mix it with the air at the heat exchange outlet before blowing it out.

[0134] When the temperature difference is greater than the second threshold, the air conditioner runs in the extreme cooling and heating mode, controls the wind uniformity arm to remain in the first position, and closes the wind uniformity component and does not operate, thereby achieving rapid adjustment of the indoor air temperature.

[0135] When the temperature difference is less than the first threshold, the air conditioner operates in the cooling mode, controls the air uniformity arm to remain in the second position, located in front of the heat exchange outlet, and makes the air uniformity component operate in the second mode, sucking in the air from the heat exchanger outlet and sending it out from the lower surface of the air uniformity arm, thereby assisting in long-distance air supply. In this way, the air supply distance can be increased, avoiding direct cold air blowing while accelerating the uniformity of indoor temperature.

[0136] Specifically, the first threshold is 2°C, and the second threshold is 5°C.

[0137] The disclosed embodiment is based on an air conditioning structure in which a uniform wind arm is arranged at the heat exchange air outlet of the air conditioner, so as to guide the indoor wind to the air outlet, and then blow it out after mixing with the wind at the air outlet. In addition, the operation strategy of the uniform wind arm is adjusted according to the temperature difference between the indoor ambient temperature and the set temperature, so that the position of the uniform wind arm and the operation parameters of the uniform wind component in the uniform wind arm can be adapted to the current indoor temperature difference, so as to adjust the air supply direction and air supply distance of the mixed air at the air outlet of the air conditioner, thereby improving the uniformity of the indoor temperature and the comfort of air supply.

[0138] Figure 7 It is a flow chart of another control method for an air conditioner provided in an embodiment of the present disclosure, which is applied to the above-mentioned air conditioner with a uniform wind arm.

[0139] The control method for air conditioning comprises:

[0140] Step S701: the processor detects the current indoor ambient temperature and obtains the temperature difference between the indoor ambient temperature and the set temperature.

[0141] Step S702: The processor determines the operation strategy of the uniform air arm according to the interval in which the temperature difference value is located.

[0142] Step S703: the processor controls the air uniforming arm according to the operation strategy to achieve different air supply modes.

[0143] Step S704: The processor determines the operation information of the air conditioner fan according to the interval where the temperature difference value is located.

[0144] Step S705: the processor controls the air conditioner fan according to the operation information to adjust the air volume at the heat exchange outlet.

[0145] The operation information of the air conditioner fan is used to adjust the air supply information from the air conditioner indoor unit to the heat exchange outlet.

[0146] In this way, by combining the air conditioning fan operation information corresponding to the different temperature difference intervals, the air volume at the heat exchange outlet is adjusted, so that the adjusted air volume is combined with the operation strategy of the wind uniformity arm to achieve different indoor temperature adjustment methods. It can improve the uniformity of indoor temperature and improve the comfort of air supply.

[0147] Furthermore, according to the interval where the temperature difference value is located, the operation information of the air conditioner fan is determined, including:

[0148] Obtaining a corresponding relationship between the difference interval and the operation information of the air-conditioning fan;

[0149] The corresponding operation information is determined according to the difference interval in which the temperature difference lies; the operation strategy includes the speed and / or air volume of the air conditioner fan.

[0150] The correspondence between the difference interval and the operation information of the air conditioner fan can be in the form of a one-to-one correspondence data table. In this case, the correspondence between the difference interval and the operation information can be stored in a database in advance. After obtaining the current temperature difference, the difference interval in which it is located is determined, and the operation information of the air conditioner fan corresponding to the current temperature difference can be obtained by querying the database.

[0151] The correspondence between the difference interval and the operating information of the air-conditioning fan can also be in the form of a formula, wherein the independent variable of the formula is determined according to the difference interval (for example, the median value of the interval is used as the independent variable of the formula), and the operating information of the air-conditioning fan is determined as the dependent variable of the formula. In this case, the formula of the difference interval and the speed and / or air volume of the air-conditioning fan can be stored in advance. After obtaining the current temperature difference, the current temperature difference, or the median value of the difference interval in which the current temperature difference is located, is used as an independent variable in the pre-stored formula, and the calculation result of the formula (speed and / or air volume) is the operating parameter of the air-conditioning fan corresponding to the current temperature difference.

[0152] Specifically, according to the interval where the temperature difference is located, the operation information of the air conditioner fan is determined, including:

[0153] When the temperature difference is greater than or equal to the first threshold, the operation information of the air conditioner fan is the first preset air volume;

[0154] When the temperature difference is less than the first threshold, the operation information of the air conditioner fan is the second preset air volume;

[0155] The first preset air volume is greater than the second preset air volume.

[0156] Here, when the temperature difference is greater than or equal to the first threshold, the air conditioning temperature adjustment demand is large, and the temperature difference between the air delivered from the indoor unit and the indoor environment temperature is large. By running a higher first preset air volume, the indoor temperature adjustment efficiency is improved.

[0157] When the temperature difference is less than the first threshold, the demand for air conditioning temperature adjustment is relatively reduced, and the temperature difference between the air delivered from the indoor unit and the indoor environment is relatively reduced. By running at a lower second preset air volume, the comfort and temperature uniformity of the whole house are improved.

[0158] In the embodiment of the present disclosure, the first preset air volume is 900m 3 / h, the second preset air volume is 700m 3 / h.

[0159] The disclosed embodiment is based on an air conditioning structure in which a uniform wind arm is provided at the heat exchange air outlet of the air conditioner, so as to guide the indoor wind to the air outlet, and then blow it out after mixing with the wind at the air outlet. In addition, the operation strategy of the uniform wind arm is adjusted by the temperature difference between the indoor ambient temperature and the set temperature, so that the position of the uniform wind arm and the operation parameters of the uniform wind component in the uniform wind arm can be adapted to the current indoor temperature difference, so as to adjust the air supply direction and air supply distance of the mixed air at the air outlet of the air conditioner, improve the uniformity of the indoor temperature, and improve the comfort of air supply. At the same time, the operation information of the air conditioner fan is further determined by the temperature difference between the indoor ambient temperature and the set temperature, and the air volume at the heat exchange air outlet is adjusted by combining the operation information of the air conditioner fan corresponding to the intervals where different temperature differences are located, so that the adjusted air volume cooperates with the operation strategy of the uniform wind arm to achieve different indoor temperature adjustment methods.

[0160] Figure 8 It is a flow chart of another control method for an air conditioner provided in an embodiment of the present disclosure, which is applied to the above-mentioned air conditioner with a uniform wind arm.

[0161] The control method for air conditioning comprises:

[0162] Step S801: The air conditioner obtains the indoor ambient temperature T1.

[0163] Step S802, the air conditioner determines the temperature difference ΔT between T1 and the set temperature Ts.

[0164] Step S803, when ΔT≥2°C, the air conditioner sets the operating information of the air conditioner fan to the first preset air volume, and the target operating position of the air uniforming arm is the first position.

[0165] Step S804: When the temperature is 2°C≤△T≤5°C, the air conditioner operates in the comfortable air supply mode and controls the air distribution component to operate in the first mode. In the first mode, the air distribution component inhales indoor air from the lower air distribution surface of the air distribution arm and blows it to the heat exchange outlet from the upper air distribution surface of the air distribution arm. Optionally, the operation information of the air distribution component is 22m 3 The wind uniformity component may be an axial flow fan, a centrifugal fan, or a cross-flow fan.

[0166] Step S805, when ΔT>5°C, the air conditioner operates in the extreme cooling and heating mode, and controls the wind uniformity component to be closed.

[0167] Step S806, when 0℃≤△T<2℃, the air conditioner operates in the cool air supply mode, the operation information of the air conditioner fan is set to the second preset air volume, the target operation position of the wind uniformity arm is the second position, and the wind uniformity component operates in the second mode. In the second mode, the wind uniformity component inhales the air at the heat exchange outlet from the wind uniformity upper surface of the wind uniformity arm and sends it out from the wind uniformity lower surface of the wind uniformity arm. The second preset air volume is smaller than the first preset air volume, the second position is located in front of the heat exchange outlet, and the first position is located at the rear of the heat exchange outlet. Optionally, the operation information of the wind uniformity component is 22m 3 The wind uniformity component may be an axial flow fan, a centrifugal fan, or a cross-flow fan.

[0168] Step S807: When the air uniformity component is turned off, the air conditioner determines whether there is a user in the air conditioner setting area. The setting area is an area formed by the projection edge of the air conditioner on the ground radiating outwards by 2 meters.

[0169] Step S808: When there is a user, the air conditioner controls the air guide plate of the air exchange outlet of the air conditioner to rise.

[0170] Step S809: In the absence of a user, the air conditioner controls the air guide plate of the air exchange outlet of the air conditioner to operate according to the setting of the extreme cooling and heating mode. Here, the air guide plate can be raised or rotated to swing the wind according to the user setting.

[0171] Step S810, the air conditioner obtains multiple indoor ambient temperatures after the first set time. Here, the multiple indoor ambient temperatures can be obtained through multiple temperature sensors set in the room, or through a temperature sensor with a long-distance temperature measurement function set on the air conditioner. It can also be obtained through sensors set on other smart home appliances that communicate with the air conditioner in the current space.

[0172] Step S811: When the difference between the average indoor ambient temperature and the set temperature is less than the third threshold, the air conditioner obtains the average variance of the indoor ambient temperature. The uniformity of the current indoor ambient temperature is determined by the average variance of the indoor ambient temperature. The third threshold can be [0°C, 0.5°C], for example, 0.1°C, 0.2°C, 0.3°C, 0.4°C. In this embodiment, the third threshold is 0°C.

[0173] Step S812: When the difference between the average indoor temperature and the set temperature is greater than or equal to the third threshold, the air conditioner uses the average indoor temperature as T1 and returns to step S801.

[0174] Step S813, when the average variance of the current indoor ambient temperature is less than the fourth threshold, the air conditioner is turned off, and the wind-uniforming arm is controlled to reciprocate between the first position and the second position within the second set time. Otherwise, return to step S801. The fourth threshold is used to indicate that the uniformity of the current ambient temperature is good. At this time, by controlling the wind-uniforming arm to reciprocate between the first position and the second position, the airflow near the air conditioner can be disturbed to further improve the uniformity of the indoor ambient temperature. In this embodiment, the fourth threshold is 1.5.

[0175] Step S814: After reaching the second set time, the air conditioner stops the operation of the wind uniforming arm and returns to step S801.
