Description

Technical Field

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

[0002] With the development of society and the continuous improvement of people's living standards, various air conditioners have become one of the indispensable electrical equipment in people's daily lives. Various air conditioners can lower or raise the ambient temperature when the ambient temperature is too high or too low, so that people are in a more comfortable environment. However, in the process of using the air conditioner, since the air blown out by the air conditioner is obtained by heat exchange through the heat exchanger, especially in the cooling mode, the temperature of the air after heat exchange is low. When the cold or hot air after heat exchange blows directly on the user, it will make the user feel uncomfortable and affect the user's experience.

[0003] In the related art, when the difference between the indoor temperature and the set temperature is large, the air volume state of the natural wind is adjusted to zero air volume or small air volume. When the difference between the indoor temperature and the set temperature is small, the air volume state of the natural wind is adjusted to large air volume to adjust the air output of the air conditioner.

[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] During the period when the air conditioner is just turned on, especially when the user just enters the room and turns on the air conditioner, the difference between the indoor temperature and the set temperature is large. In order to achieve rapid cooling, the air conditioner will be selected to output air with a large air volume and a high wind speed. At this time, mixing cannot be achieved in the relevant technology. Air with a large temperature difference from the indoor temperature is blown towards the user, which can easily cause discomfort to the user. For example, when colder air blows towards the user, it is easy for the user to catch a cold, reducing the user's experience.

[0038] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0040] Unless otherwise stated, the term "plurality" means two or more.

[0041] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0042] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0043] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0044] The present disclosure provides an air conditioner, such as Figures 1 to 8 As shown, the air conditioner includes a heat exchange fan 200 and a mixing fan 300. The air outlet of the mixing fan 300 is arranged at the air inlet position of the heat exchange fan 200. The mixing fan 300 can drive the indoor air that has not been heat exchanged to mix with the heat exchange air driven by the heat exchange fan 200.

[0045] In this way, the indoor air that has not been heat exchanged is mixed with the heat exchanged air to reduce the temperature difference between the air outlet temperature of the air conditioner and the indoor temperature, reducing the occurrence of users feeling over-cooled or over-heated air, thereby improving the user experience.

[0046] Optionally, the heat exchange fan 200 includes a crossflow fan, the axial side wall of the crossflow fan is provided with an auxiliary air inlet 210 connected to the interior of the crossflow fan, the air inlet position of the heat exchange fan 200 includes the air inlet position of the auxiliary air inlet 210, and the air outlet of the mixing fan 300 is connected to the auxiliary air inlet 210.

[0047] In this embodiment, the auxiliary air inlet 210 is arranged on the axial side wall of the crossflow fan, and the indoor air driven by the air mixing fan 300 is blown into the inside of the crossflow fan along the axial direction of the crossflow fan through the auxiliary air inlet 210. The heat exchange air passes through the crossflow fan along the radial direction of the crossflow fan, and the flow direction of the heat exchange air and the indoor air is different, so that the mixing effect of the indoor air and the heat exchange air can be improved in the process of mixing. Thereby, the temperature uniformity of the mixed air blown out by the air conditioner is improved, and the user experience is improved.

[0048] Furthermore, during the rotation of the air mixing fan 300, the rotation speed of the air mixing fan 300 is greater than the rotation speed of the cross flow fan, so as to increase the flow length of the indoor air in the radial direction of the cross flow fan inside the cross flow fan, thereby improving the mixing effect of the heat exchange air and the indoor air, and improving the uniformity of the temperature of the mixed air blown out by the air conditioner.

[0049] Furthermore, the air conditioner further includes a first motor 410 and a second motor 420. The crossflow fan is used to drive the heat exchange air to flow, and along the axial direction of the crossflow fan, the side wall of the crossflow fan is provided with an auxiliary air inlet 210 connected to the inside of the crossflow fan. The driving end of the first motor 410 is connected to the crossflow fan. The mixed air fan 300 is used to drive the indoor air that has not been heat exchanged to flow, the air outlet of the mixed air fan 300 is connected to the auxiliary air inlet 210, and the driving end of the second motor 420 is connected to the connecting shaft 310 of the mixed air fan 300.

[0050] With this optional embodiment, the crossflow fan can drive the heat exchange wind to flow, and the axial side wall of the crossflow fan is provided with an auxiliary air inlet 210 connected to the inside of the crossflow fan, and the air outlet of the mixing fan 300 is connected to the auxiliary air inlet 210, and the mixing fan 300 can drive the indoor wind that has not been heat exchanged to flow into the crossflow fan. The indoor wind that has not been heat exchanged can enter the auxiliary air inlet 210 driven by the mixing fan 300 and flow into the inside of the crossflow fan, and mix with the heat exchange wind inside the crossflow fan. In this way, the heat exchange wind and the indoor wind are mixed, so as to adjust the temperature of the wind blown out by the air conditioner. And the air conditioner includes a crossflow fan and a mixing fan 300, so that the air outlet of the air conditioner can be increased to transfer the cold or heat of the heat exchange wind to more air. Thereby increasing or decreasing the temperature of the mixed wind blown out by the air conditioner, reducing the temperature difference between the wind blown out by the air conditioner and the indoor temperature, and improving the comfort of the user.

[0051] In this embodiment, the first motor 410 can rotate synchronously with the second motor 420, so that the rotation speed of the crossflow fan is the same as the rotation speed of the air mixing fan 300. The first motor 410 can also rotate asynchronously with the second motor 420, so that the rotation speed of the crossflow fan is different from the rotation speed of the air mixing fan 300, so as to adjust the ratio of indoor air to heat exchange air during air mixing and the air volume of the air conditioner. Similarly, the first motor 410 can be rotated and the second motor 420 can not be rotated, so that the indoor air that has not been heat exchanged cannot flow into the inside of the crossflow fan, and no air mixing is performed, so that the air conditioner can discharge air normally. In this way, the air conditioner can have a variety of air outlet modes to meet the various air outlet needs of users and improve the user experience.

[0052] Furthermore, if Figures 2 to 3 As shown, the mixed air fan 300 is arranged on the side of the cross-flow fan provided with an auxiliary air inlet 210, and the air conditioner also includes a volute 130, and the cross-flow fan is arranged in the volute 130. The first axial side wall 131 of the volute 130 is arranged opposite to the auxiliary air inlet 210, and the first axial side wall 131 is provided with a mounting assembly 600, and the second motor 420 is connected to the mounting assembly 600.

[0053] With this optional embodiment, the crossflow fan is arranged in the volute 130, so that a vortex can be formed inside the crossflow fan when the crossflow fan rotates, thereby driving the heat exchange air to flow. The mixed air fan 300 is arranged on the side of the crossflow fan provided with the auxiliary air inlet 210, and the first axial side wall 131 of the volute 130 is arranged opposite to the auxiliary air inlet 210, that is, the first axial side wall 131 and the mixed air fan 300 are arranged on the same side of the crossflow fan. The first axial side wall 131 is provided with a mounting assembly 600, and the second motor 420 is connected to the mounting assembly 600, so as to arrange the second motor 420 on the first axial side wall 131, thereby fixing the mixed air fan 300.

[0054] Alternatively, if Figure 3As shown, the indoor air conditioner of the air conditioner also includes a housing 100, the housing 100 is configured with an air inlet duct, an air outlet duct and an auxiliary air inlet duct, the volute 130 is configured with a housing chamber 110, and the crossflow fan is located in the housing chamber 110. The air inlet duct and the air outlet duct are respectively connected to the two ends of the housing chamber 110, and the auxiliary air inlet duct is connected to the auxiliary air inlet 210. A heat exchanger is arranged in the air inlet duct. Along the flow direction of the heat exchange air, the heat exchanger and the crossflow fan are arranged in sequence. The indoor air enters the air inlet duct under the drive of the crossflow fan, and exchanges heat with the heat exchanger in the air inlet duct to form heat exchange air. After flowing along the air inlet duct, the heat exchange air flows into the housing chamber 110 to enter the interior of the crossflow fan. The other indoor air flows into the auxiliary air inlet duct under the drive of the mixing fan 300, and flows into the interior of the crossflow fan through the auxiliary air inlet duct and the auxiliary air inlet 210 to form mixed air after mixing with the heat exchange air inside the crossflow fan. The mixed air flows out of the cross-flow fan, flows into the air outlet duct, and then flows out of the casing 100 to achieve mixed air outlet of the air conditioner.

[0055] In some optional embodiments, such as Figures 4 to 7 As shown, the first axial side wall 131 is provided with an air inlet opening 132, and the air mixing fan 300 drives the indoor air to enter the auxiliary air inlet 210 through the air inlet opening 132. The mounting assembly 600 includes a mounting plate 610 and a mounting protrusion 620. The mounting plate 610 is connected to the inner side wall of the air inlet opening 132, and the mounting plate 610 is provided with a vent 611, and the vent 611 is connected to the air inlet opening 132. The mounting protrusion 620 is connected to the mounting plate 610, and the second motor 420 is connected to the mounting protrusion 620.

[0056] With this optional embodiment, the indoor wind enters the auxiliary air inlet 210 through the air inlet opening 132, so that the indoor wind can pass through the volute 130 and flow into the interior of the crossflow fan along the axial direction of the crossflow fan. The mounting plate 610 is connected to the inner side wall of the air inlet opening 132, and the inner side wall of the air inlet opening 132 can fix the mounting plate 610. The mounting protrusion 620 is connected to the mounting plate 610, and the second motor 420 is disposed on the mounting protrusion 620 to fix the second motor 420.

[0057] The mounting plate 610 is disposed in the air inlet opening 132, and the mounting plate 610 is provided with a vent 611, which is connected to the air inlet opening 132, so that the indoor air flowing to the air inlet opening 132 can flow to the auxiliary air inlet 210 through the vent 611, so that the air inlet opening 132 can not only fix the mounting plate 610, but also ventilate.

[0058] The air inlet opening 132 can be coaxially arranged with the auxiliary air inlet 210, and the mounting plate 610 and the mounting protrusion 620 are arranged in the air inlet opening 132, so that the driving end of the second motor 420 can be coaxially arranged with the cross-flow fan, thereby making the mixing fan 300 coaxially arranged with the cross-flow fan.

[0059] Further, the air inlet opening 132 is connected between the auxiliary air inlet duct and the auxiliary air inlet 210 .

[0060] Furthermore, the second motor 420 is arranged on one side of the mounting plate 610, and the mixing fan 300 is arranged on the other side of the mounting plate 610. The mounting plate 610 is provided with a through hole, and the driving end of the second motor 420 is connected to the connecting shaft 310 through the through hole, or the connecting shaft 310 is connected to the second motor 420 through the through hole.

[0061] With this optional embodiment, the second motor 420 and the mixing air fan 300 are respectively arranged on both sides of the mounting plate 610. When the driving end of the second motor 420 passes through the through hole of the mounting plate 610 and is connected to the connecting shaft 310, the driving end of the second motor 420 is rotatably connected to the through hole. The through hole can radially limit the driving end of the second motor 420, thereby reducing the radial shaking of the driving end of the second motor 420 and the mixing air fan 300 during rotation, thereby improving the working stability and reliability of the air conditioner.

[0062] When the connecting shaft 310 passes through the through hole and is connected to the second motor 420, the connecting shaft 310 is rotatably connected to the through hole, and the through hole can radially limit the connecting shaft 310, thereby reducing the radial shaking of the mixing fan 300 during rotation and improving the working stability and reliability of the air conditioner.

[0063] Optionally, the mounting protrusion 620 is connected to a side wall of the mounting plate 610 facing away from the auxiliary air inlet 210 .

[0064] In this embodiment, the mounting protrusion 620 is connected to the side wall of the mounting plate 610 away from the auxiliary air inlet 210, the second motor 420 is connected to the mounting protrusion 620, and the second motor 420 and the air mixing fan 300 are respectively arranged on two opposite sides of the mounting plate 610. In other words, the air mixing fan 300 is arranged on the side of the mounting plate 610 facing the auxiliary air inlet 210.

[0065] Driven by the mixing fan 300, the indoor air first passes through the second motor 420 into the air inlet opening 132, passes through the air inlet opening 132 and the vent 611, and then flows through the mixing fan 300. Driven by the mixing fan 300, the indoor air flows into the cross-flow fan through the auxiliary air inlet 210 to mix with the heat exchange air inside the cross-flow fan, and then flows out of the cross-flow fan and the air conditioner together.

[0066] For example, Figure 7 and Figure 8As shown, the mounting plate 610 includes a plurality of sub-mounting plates 612 and a fixed shaft 613. Along the radial direction of the air inlet opening 132, the two ends of the sub-mounting plates 612 are respectively connected to the inner side wall of the air inlet opening 132 and the circumferential side wall of the fixed shaft 613. The plurality of sub-mounting plates 612 are arranged at intervals along the circumference of the air inlet opening 132. A vent 611 is defined between two adjacent sub-mounting plates 612. The fixed shaft 613 is provided with a through hole. The air conditioner also includes a sealing member 630, which is rotatably connected to the mounting plate 610 to open or close the vent 611.

[0067] With this optional embodiment, the sub-mounting plate 612 is connected to the inner side wall of the air inlet opening 132, and the sealing member 630 is connected to the mounting plate 610, so that the sealing member 630 is arranged in the air inlet opening 132. The sealing member 630 can move relative to the vent 611 to open or seal the vent 611. In this way, when the sealing member 630 opens the vent 611, the indoor air that has not been heat exchanged can flow through the vent 611 in the air inlet opening 132, that is, the indoor air can enter the cross flow fan for mixing. When the sealing member 630 seals the vent 611, the sealing member 630 blocks the flow of indoor air, that is, the indoor air cannot flow at the air inlet opening 132 to enter the cross flow fan for mixing.

[0068] In this embodiment, the mounting plate 610 can not only mount the second motor 420, but also cooperate with the sealing member 630 to seal or open the air inlet opening 132. This reduces the number of components used to seal the air inlet opening 132 or to mount the second motor 420, thereby improving the utilization rate of the components and reducing the production cost of the air conditioner.

[0069] Optionally, when the air mixing fan 300 rotates, the seal 630 opens the vent 611, and when the air mixing fan 300 stops rotating, the seal 630 seals the vent 611. In this way, when the air conditioner does not mix the air, the pressure difference between the inside of the cross flow fan and the outside of the air conditioner can be reduced when the cross flow fan rotates alone, driving the indoor air without heat exchange to flow into the inside of the cross flow fan through the auxiliary air inlet 210. In the case of normal air discharge, the mixing of indoor air and heat exchange air can be reduced, thereby improving the air discharge effect of the air conditioner.

[0070] Optionally, a fixed shaft 613 is provided in the middle of the mounting plate 610, and the sealing member 630 includes a rotating plate 631 and a sealing plate 632, wherein the rotating plate 631 is arranged in an annular shape, and the rotating plate 631 is sleeved on the outside of the fixed shaft 613, and the rotating plate 631 is rotatably connected to the fixed shaft 613. One end of the sealing plate 632 is connected to the rotating plate 631, and the number of the sealing plates 632 is the same as the number of the vents 611 and corresponds one to one, and the sealing plates 632 can rotate relative to the vents 611 to open or seal the vents 611.

[0071] In this embodiment, the rotating plate 631 is rotatably connected to the fixed shaft 613 , one end of the sealing plate 632 is connected to the rotating plate 631 , and the sealing plate 632 can rotate synchronously with the rotating plate 631 relative to the vent 611 to open or seal the vent 611 .

[0072] Alternatively, if Figure 7 and Figure 8 As shown, an annular rack 6311 is provided at the end of the rotating plate 631, and the air conditioner also includes a first driving assembly and a first gear 640, the first driving assembly is connected to the fixed shaft 613, the first gear 640 is connected to the driving end of the first driving assembly, and the first gear 640 is meshed with the annular rack 6311.

[0073] In this embodiment, the first drive assembly is connected to the fixed shaft 613 to fix the first drive assembly. The driving end of the first drive assembly is connected to the first gear 640, and the first drive assembly drives the first gear 640 to rotate. The first gear 640 is engaged with the annular rack 6311 of the rotating plate 631. The rotation of the first gear 640 drives the annular rack 6311 to rotate, thereby driving the rotating plate 631 to rotate relative to the fixed shaft 613.

[0091] Fig. 9 1 is a flow chart of a control method for an air conditioner provided by an embodiment of the present disclosure. The control method for an air conditioner can be executed in a controller of the air conditioner.

[0092] S011, the controller obtains the wind speed of the heat exchange fan and the air outlet temperature of the air conditioner.

[0093] S012, the controller controls the operation of the mixed air fan according to the wind speed and outlet air temperature of the heat exchange fan.

[0094] In this embodiment, the wind speed of the heat exchange fan and the outlet air temperature of the air conditioner can be obtained to determine the operating state of the air conditioner. And according to the wind speed and outlet air temperature of the heat exchange fan, the operation of the mixing fan is controlled, so as to adjust the mixing effect of the indoor air without heat exchange driven by the mixing fan and the heat exchange air driven by the heat exchange fan, so as to adjust the outlet air temperature of the air conditioner, reduce the discomfort caused by the air conditioner outlet to the user, and improve the user experience.

[0095] Fig.10 1 is a flow chart of another control method for an air conditioner provided by an embodiment of the present disclosure. The control method for an air conditioner can be executed in a controller of the air conditioner.

[0096] S021, the controller obtains the wind speed of the heat exchange fan and the air outlet temperature of the air conditioner.

[0097] S022, the controller determines a first temperature difference between the outlet air temperature and the target temperature.

[0098] S023, when the wind speed of the heat exchange fan is greater than or equal to the preset wind speed and the first temperature difference is greater than or equal to the first preset difference, the controller increases the wind speed of the air mixing fan.

[0099] S024: When the wind speed of the heat exchange fan is greater than or equal to the preset wind speed and the first temperature difference is less than the first preset difference, the controller reduces the wind speed of the air mixing fan.

[0100] With this optional embodiment, when the wind speed of the heat exchange fan is greater than or equal to the preset wind speed, it means that the air outlet wind speed of the air conditioner is relatively high, the air conditioner is just turned on, or the air outlet wind speed of the air conditioner set by the user is relatively high, so as to quickly cool the room. At this time, the mixed air fan is turned on, so that the mixed air fan drives the indoor air to flow into the air conditioner and mix with the heat exchange air driven by the heat exchange fan to achieve mixed air outlet of the air conditioner, reduce the air outlet temperature of the air conditioner, and reduce the large difference between the air outlet temperature of the air conditioner and the indoor temperature, which may cause discomfort to the user.

[0101] Optionally, when the wind speed of the heat exchange fan is less than a preset wind speed, the air mixing fan is controlled to be turned off.

[0102] In this embodiment, the preset wind speed may be less than or equal to the set distance between the user and the air outlet, and the minimum wind speed at the air outlet of the air conditioner can be felt by the user when the air conditioner is exhausted. Optionally, the set distance ranges from 0.5 meters to 5 meters. For example, the specific setting is 0.5 meters, 1 meter, 1.5 meters, 2 meters, 2.5 meters, 3 meters, 3.5 meters, 4 meters, 4.5 meters, 5 meters, etc.

[0103] Optionally, the preset wind speed can be set when the air conditioner is produced, or it can be set by the user according to his or her own situation, or it can be set intelligently by the controller detecting the distance between the user and the air outlet of the air conditioner.

[0104] Exemplarily, the controller obtains the shortest user distance between the user and the air outlet of the air conditioner; the controller determines the preset wind speed according to the user distance and the relationship between the distance and the wind speed. Optionally, the relationship between the distance and the wind speed can be obtained by experiments or calculations by production personnel during the production of the air conditioner and pre-stored in the memory of the air conditioner.

[0105] In this embodiment, when the first temperature difference is greater than or equal to the first preset difference, the outlet air temperature of the air conditioner differs greatly from the target temperature, and when the overcooled air or overheated air blows on the user, it will cause discomfort to the user. At this time, the controller increases the wind speed of the mixing air fan to increase the air volume of the indoor air mixed with the heat exchange air driven by the heat exchange fan, and reduces the difference between the mixed air, that is, the outlet air temperature of the air conditioner and the target temperature, thereby improving the user's experience.

[0106] When the first temperature difference is less than the first preset difference, the air outlet temperature of the air conditioner is slightly different from the target temperature, and the user feels that the air conditioner is in a more comfortable state when it is blowing air. At this time, the wind speed of the mixing fan can be reduced, thereby reducing the energy consumption of the mixing fan and the air conditioner.

[0107] Optionally, the target temperature is the air outlet temperature of the air conditioner corresponding to the user's comfortable body temperature.

[0108] Furthermore, the control method for the air conditioner also includes:

[0109] S0221, the controller obtains indoor environmental parameters and indoor user types.

[0110] S0222, the controller determines the user's comfortable body temperature based on the indoor user type.

[0111] In this embodiment, the controller can determine the user's comfortable body temperature according to the user type, so as to determine different comfortable body temperatures for different users in the room, thereby improving the intelligence of the air outlet temperature of the air conditioner.

[0112] Optionally, the indoor user type includes user age, user gender, user status, etc. Optionally, the indoor user type may also include a specific user, and when the controller determines that the user type is a specific user, the controller determines that the temperature corresponding to the specific user is the comfortable body temperature of the specific user according to the preset body temperature relationship.

[0113] S0223, the controller determines the target temperature based on the comfortable body temperature, indoor humidity and air conditioning wind speed.

[0114] Optionally, the controller determines the target temperature by the following formula:

[0115]

[0116] Among them, T m is the target temperature, T a is the comfortable perceived temperature, E is the temperature adjustment value corresponding to the indoor humidity, k1 is the air conditioning outlet wind speed adjustment coefficient, V is the air conditioning outlet wind speed, k2 is the first adjustment coefficient, and k3 is the second adjustment coefficient.

[0117] This embodiment can determine the user's comfortable perceived temperature according to the user type. Due to the influence of factors such as wind speed, room temperature and humidity, the indoor temperature of the room where the user is located is not the perceived temperature felt by the user. Therefore, if the indoor temperature is adjusted to a comfortable perceived temperature, the temperature felt by the user is not the comfortable perceived temperature corresponding to the user. In the disclosed embodiment, the target temperature, that is, the indoor temperature, is determined based on the comfortable perceived temperature, indoor humidity and air-conditioning outlet wind speed. That is, when the indoor temperature is the target temperature, the perceived temperature felt by the user is a comfortable perceived temperature, thereby improving the user's comfort and user experience.

[0118] Furthermore, k1 is negatively correlated with the distance between the user and the air outlet of the air conditioner. The greater the distance between the user and the air outlet of the air conditioner, the smaller k1 is, and the smaller the distance between the user and the air outlet of the air conditioner, the larger k1 is. Optionally, k1 is less than or equal to 0.65.

[0119] In this embodiment, V is the wind speed of the air conditioner. There is a certain distance between the user and the air outlet of the air conditioner. The farther the user is from the air outlet of the air conditioner, the smaller the wind speed felt by the user; the closer the user is to the air outlet of the air conditioner, the larger the wind speed felt by the user.

[0120] Optionally, the value range of k2 is 2.5 to 3, for example, k2 may be 2.5, 2.6, 2.7, 2.8, 2.9, 3, etc. Preferably, k2 is 2.7.

[0121] Optionally, the value range of k3 is 1.05 to 1.1. For example, k3 may be 1.05, 1.06, 1.07, 1.08, 1.09, etc. Preferably, k3 is 1.07.

[0122] Optionally, E=0.2e, wherein e is the water vapor pressure.

[0123] The controller determines the water vapor pressure e by the following formula:

[0124]

[0125] Among them, RH is the indoor humidity and T is the current actual indoor temperature.

[0126] Fig.11 1 is a flow chart of another control method for an air conditioner provided by an embodiment of the present disclosure. The control method for an air conditioner can be executed in a controller of the air conditioner.

[0127] S031, the controller obtains the wind speed of the heat exchange fan and the air outlet temperature of the air conditioner.

[0128] S032, the controller controls the operation of the mixed air fan according to the wind speed and outlet air temperature of the heat exchange fan.

[0129] S033, the controller determines a second temperature difference between the first indoor temperature and the first preset temperature.

[0130] S034, the controller controls the wind speed of the heat exchange fan and the wind speed of the mixing fan according to the second temperature difference.

[0131] In this embodiment, the controller also controls the wind speed of the heat exchange fan and the wind speed of the mixing fan according to the second temperature difference between the first indoor temperature and the first preset temperature, so as to adjust the air outlet speed and air outlet temperature of the air conditioner according to the first indoor temperature, so that the air outlet speed and the first indoor temperature of the air conditioner meet the user's comfort needs and improve the user's experience.

[0132] Fig.12 1 is a flow chart of another control method for an air conditioner provided by an embodiment of the present disclosure. The control method for an air conditioner can be executed in a controller of the air conditioner.

[0133] S041, the controller obtains the wind speed of the heat exchange fan and the air outlet temperature of the air conditioner.

[0134] S042, the controller controls the operation of the mixing air fan according to the wind speed and outlet air temperature of the heat exchange fan.

[0135] S043, the controller determines a second temperature difference between the first indoor temperature and the first preset temperature.

[0136] S044: When the second temperature difference is greater than or equal to the second preset difference, the controller controls the wind speed of the heat exchange fan to be the set wind speed.

[0137] S045, when the second temperature difference is less than the second preset difference, the controller controls the sum of the wind speed of the heat exchange fan and the wind speed of the mixing fan to be the set wind speed.

[0138] Optionally, the set wind speed is the air outlet wind speed of the air conditioner set by the user.

[0139] In this embodiment, the controller determines the second difference between the first indoor temperature and the first preset temperature. When the second temperature difference is greater than or equal to the second preset difference, it is necessary to quickly cool or heat the room to reduce the difference between the first indoor temperature and the first preset temperature and improve the user's comfort in the room. At this time, the controller controls the wind speed of the heat exchange fan to be the set wind speed, and the wind speed of the mixed air fan is controlled according to the wind speed and outlet air temperature of the heat exchange fan to increase the heat exchange amount of the heat exchange air driven by the heat exchange fan, thereby achieving rapid cooling or heating of the room. In addition, in this embodiment, the mixed air fan works according to the wind speed and outlet air temperature of the heat exchange fan. When the heat exchange amount of the heat exchange air of the heat exchange fan increases, the speed of the mixed air fan also increases accordingly, increasing the air volume of the indoor air mixed with the heat exchange air, so as to reduce the difference between the temperature of the mixed outlet air of the air conditioner and the indoor temperature, and improve the user's experience.

[0140] When the second temperature difference is less than the second preset difference, that is, the temperature difference between the first indoor temperature and the first preset temperature is small, it is not necessary to quickly cool or heat the room. In this way, the controller controls the sum of the wind speed of the heat exchange fan and the wind speed of the mixing fan to be the set wind speed, so as to reduce the air outlet wind speed of the air conditioner and the wind speed of the heat exchange fan, thereby reducing the energy consumption required for the operation of the air conditioner.

[0141] In some optional embodiments, the controller controls the sum of the wind speed of the heat exchange fan and the wind speed of the mixing fan to be the set wind speed, including:

[0142] S0451, the controller determines the absolute value of the temperature difference between the second indoor temperature and the second preset temperature.

[0143] S0452, the controller adjusts the wind speed of the heat exchange fan and the wind speed of the mixing fan according to the second indoor temperature and the absolute value of the temperature difference until the sum of the wind speed of the heat exchange fan and the wind speed of the mixing fan reaches the set wind speed.

[0144] In this embodiment, the controller adjusts the wind speed of the heat exchange fan and the mixed air speed according to the second indoor temperature and the absolute value of the temperature difference, so that the second indoor temperature is further close to the second preset temperature, the absolute value of the temperature difference is reduced, and the air conditioner can also mix the air, thereby reducing the discomfort caused to the user by the mixed air output of the air conditioner and improving the user experience.

[0145] Furthermore, before determining the absolute value of the temperature difference between the second indoor temperature and the second preset temperature, the controller further reduces the wind speed of the heat exchange fan to a target wind speed. Optionally, the target wind speed is less than or equal to half of the set wind speed.

[0146] Optionally, when the set wind speed is greater than or equal to the preset wind speed, the controller controls the mixed air fan to rotate. That is, when the set wind speed is greater than or equal to the preset wind speed and the target wind speed is less than the preset wind speed, the controller still controls the mixed air fan to rotate to achieve mixed air output of the air conditioner.

[0147] Exemplarily, in the case of the air conditioning cooling operation mode, the controller adjusts the wind speed of the heat exchange fan and the wind speed of the mixing fan according to the second indoor temperature and the absolute value of the temperature difference until the sum of the wind speed of the heat exchange fan and the wind speed of the mixing fan is the set wind speed, including:

[0148] When the second indoor temperature is greater than the second preset temperature and the absolute value of the temperature difference is greater than or equal to the third preset difference, the controller increases the wind speed of the heat exchange fan and decreases the wind speed of the air mixing fan.

[0149] In this embodiment, when the second indoor temperature is greater than the second preset temperature, and the absolute value of the temperature difference is greater than or equal to the third preset difference, it means that the indoor temperature is high. At this time, the controller increases the wind speed of the heat exchange fan, that is, increases the proportion of heat exchange air in the mixed air outlet of the air conditioner, so as to increase the heat exchange amount of the heat exchange fan, increase the rate of reducing the indoor temperature, achieve rapid indoor cooling, and improve the user experience. The controller also reduces the wind speed of the mixed air fan, that is, reduces the proportion of heat exchange air in the mixed air outlet of the air conditioner, and maintains the air outlet wind speed of the air conditioner at the set wind speed, so as to reduce the air outlet temperature of the air conditioner, increase the indoor cooling rate, and improve the user experience.

[0150] When the second indoor temperature is lower than the second preset temperature and the absolute value of the temperature difference is greater than or equal to the third preset difference, the controller reduces the wind speed of the heat exchange fan and increases the wind speed of the air mixing fan.

[0151] In this embodiment, when the second indoor temperature is lower than the second preset temperature, and the absolute value of the temperature difference is greater than or equal to the third preset difference, it means that the indoor temperature is relatively low. At this time, the controller reduces the wind speed of the heat exchange fan, that is, reduces the proportion of heat exchange air in the mixed air outlet of the air conditioner, so as to reduce the amount of cold air blown out by the air conditioner, reduce the occurrence of excessively low indoor temperature, and improve the user experience. The controller also increases the wind speed of the mixed air fan, that is, increases the proportion of mixed air in the mixed air outlet of the air conditioner, and maintains the air outlet wind speed of the air conditioner at the set wind speed. The content of indoor air that has not been heat exchanged in the mixed air blown out by the air conditioner increases, so as to reduce the difference between the air outlet temperature of the air conditioner and the indoor temperature, and improve the user experience.

[0152] Further, when the second indoor temperature is equal to the second preset temperature, or when the absolute value of the temperature difference is less than a third preset difference, the controller controls the wind speed of the heat exchange fan to remain unchanged, and the wind speed of the air mixing fan to remain unchanged.

[0153] Optionally, when the second indoor temperature is greater than the second preset temperature and the absolute value of the temperature difference is greater than or equal to a third preset difference, the ratio of the wind speed of the heat exchange fan to the wind speed of the mixing fan is in a range of 5:5 to 7:3.

[0154] When the second indoor temperature is lower than the second preset temperature and the absolute value of the temperature difference is greater than or equal to the third preset difference, the ratio of the wind speed of the heat exchange fan to the wind speed of the mixing fan is in the range of 2:8 to 5:5.

[0155] Further, in the case of the air conditioning heating operation mode, the controller adjusts the wind speed of the heat exchange fan and the wind speed of the mixing fan according to the second indoor temperature and the absolute value of the temperature difference until the sum of the wind speed of the heat exchange fan and the wind speed of the mixing fan reaches the set wind speed, including:

[0156] When the second indoor temperature is greater than the second preset temperature and the absolute value of the temperature difference is greater than or equal to the third preset difference, the controller reduces the wind speed of the heat exchange fan and increases the wind speed of the air mixing fan.

[0157] In this embodiment, when the second indoor temperature is greater than the second preset temperature, and the absolute value of the temperature difference is greater than or equal to the third preset difference, it means that the indoor temperature is high. At this time, the controller reduces the wind speed of the heat exchange fan, that is, reduces the proportion of heat exchange air in the mixed air outlet of the air conditioner, so as to reduce the heat blown out by the air conditioner, reduce the occurrence of excessively high indoor temperature, and improve the user experience. The controller also increases the wind speed of the mixed air fan, that is, increases the proportion of mixed air in the mixed air outlet of the air conditioner, and maintains the air outlet wind speed of the air conditioner at the set wind speed. The content of indoor air that has not been heat exchanged in the mixed air blown out by the air conditioner increases, so as to reduce the difference between the air outlet temperature of the air conditioner and the indoor temperature, and improve the user experience.

[0158] When the second indoor temperature is lower than the second preset temperature and the absolute value of the temperature difference is greater than or equal to the third preset difference, the controller increases the wind speed of the heat exchange fan and decreases the wind speed of the air mixing fan.

[0159] In this embodiment, when the second indoor temperature is less than the second preset temperature, and the absolute value of the temperature difference is greater than or equal to the third preset difference, it means that the indoor temperature is low. At this time, the controller increases the wind speed of the heat exchange fan, that is, increases the proportion of heat exchange air in the mixed air outlet of the air conditioner, so as to increase the heat exchange amount of the heat exchange fan, increase the rate of increasing the indoor temperature, achieve rapid indoor temperature rise, and improve the user experience. The controller also reduces the wind speed of the mixed air fan, that is, reduces the proportion of heat exchange air in the mixed air outlet of the air conditioner, and maintains the air outlet wind speed of the air conditioner at the set wind speed, so as to increase the air outlet temperature of the air conditioner, increase the indoor temperature rise rate, and thus improve the user experience.

[0160] Optionally, when the second indoor temperature is greater than the second preset temperature and the absolute value of the temperature difference is greater than or equal to a third preset difference, the ratio of the wind speed of the heat exchange fan to the wind speed of the mixing fan is in a range of 3:7 to 5:5.

[0161] When the second indoor temperature is lower than the second preset temperature and the absolute value of the temperature difference is greater than or equal to the third preset difference, the ratio of the wind speed of the heat exchange fan to the wind speed of the mixing fan is in the range of 5:5 to 8:2.
