Description

[0002] With the improvement of living standards, household air conditioners have become a must-have household appliance, and the requirements for the quality and health of air conditioners are getting higher and higher. When the air conditioner is running, a large amount of air flows through the indoor heat exchanger for heat exchange. After a period of time, the dust in the air will adhere to the heat exchanger and air duct in the indoor unit. When the air conditioner is cooling, the indoor unit becomes humid due to the generation of condensed water. In a humid environment, the dust attached to the indoor unit is prone to mold growth, thereby generating odor and affecting the user experience.

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] According to an embodiment of the present invention, a method for controlling an air conditioner is provided, wherein a first air guide plate and a second air guide plate are arranged at the air outlet of an indoor unit of the air conditioner; the first air guide plate is used to adjust the air outlet direction of the upper area of ​​the air outlet of the indoor unit; and the second air guide plate is used to adjust the air outlet direction of the lower area of ​​the air outlet of the indoor unit.

[0033] The structure of the indoor unit of the air conditioner is as follows Figure 3 As shown, the indoor unit includes: an evaporator 1, a crossflow fan blade 2, a panel 3, first air guide plates 4-6, second air guide plates 7-8, and a return air grille 9. The first air guide plates 4-6 are the positions of the first air guide plates at three preset air guide angles, and the second air guide plates 7-8 are the positions of the second air guide plates at two preset air guide angles. The first air guide plate is opened around the rotating axis toward the outside of the indoor unit, and the second air guide plate is opened around the rotating axis toward the inside of the indoor unit.

[0034] The three preset wind guide angles of the first wind guide plate include: a preset first angle, a preset second angle, and a preset third angle. Figure 3 In the figure, the first angle is preset to be the angle shown by the first air guide plate 6, the second angle is preset to be the angle shown by the first air guide plate 5, and the third angle is preset to be the angle shown by the first air guide plate 4.

[0035] The angle of the first air guide plate when closed is 0°, and the greater the opening range of the first air guide plate is, the greater the air guide angle is, and therefore the preset first angle>the preset second angle>the preset third angle.

[0036] Optionally, the preset range of the first wind guide angle is 40° to 50°, the preset range of the second wind guide angle is 30° to 40°, and the preset range of the third angle is 20° to 30°.

[0037] The second air guide plate has two preset air guide angles including: a preset fourth angle and a preset fifth angle. Figure 3 In the embodiment, the fourth angle is preset to be the angle shown by the second air guide plate 7, and the fifth angle is preset to be the angle shown by the second air guide plate 8.

[0038] The angle of the second air guide plate when closed is 0°, and the greater the opening amplitude of the second air guide plate is, the greater the air guide angle is, and therefore the preset fourth angle is less than the preset fifth angle.

[0039] Optionally, the fourth angle is preset to 0°, ie, the second air guide plate is closed, and the fifth angle is preset to range from 20° to 30°.

[0040] like Figure 1 The flowchart of an embodiment of the method of the present invention is shown in FIG. The air conditioner control method may include: step S110 and step S120.

[0041] In step S110, after the air conditioner refrigeration is started and after the air conditioner refrigeration is stopped, the pipe temperature of the indoor heat exchanger is obtained.

[0042] The air conditioner will produce odor in heating mode, and after the cooling mode is stopped, the internal fan will not stop running immediately, and the air guide plate will not close immediately. The air conditioner will still blow out residual cold, which will also produce odor. Therefore, odor removal is required during the cooling operation of the air conditioner and after the cooling mode is stopped.

[0043] In step S120, the air guiding angle of the first air guiding plate and the air guiding angle of the second air guiding plate are controlled according to the tube temperature of the indoor heat exchanger.

[0044] This solution controls the angle of the air guide plate when the air conditioner is turned on or off. Without increasing the equipment manufacturing cost, it blows the air toward the ceiling at the pipe temperature when odor may be generated, instead of directly toward the user area, thereby alleviating the impact of odor from the air conditioner indoor unit on the user.

[0045] In some embodiments, in step S120, the specific process of controlling the air guide angle of the first air guide plate and the air guide angle of the second air guide plate according to the tube temperature of the indoor heat exchanger includes: steps S210 to S260.

[0046] Step S210, determining the temperature range of the tube temperature of the indoor heat exchanger, including a first temperature range, a second temperature range, a third temperature range, a fourth temperature range, and a fifth temperature range.

[0047] Step S220: If the tube temperature of the indoor heat exchanger is within a first temperature range, the air guide angle of the first air guide plate is controlled to be a preset first angle, and the air guide angle of the second air guide plate is controlled to be a preset fourth angle.

[0048] Step S230: If the pipe temperature of the indoor heat exchanger is within the second temperature range, the air guide angle of the first air guide plate is controlled to be a preset second angle, and the air guide angle of the second air guide plate is controlled to be a preset fourth angle.

[0049] Step S240: If the tube temperature of the indoor heat exchanger is within a third temperature range, the air guide angle of the first air guide plate is controlled to be a preset third angle, and the air guide angle of the second air guide plate is controlled to be a preset fourth angle.

[0050] Step S250: If the tube temperature of the indoor heat exchanger is within a fourth temperature range, the air guide angle of the first air guide plate is controlled to be a preset second angle, and the air guide angle of the second air guide plate is controlled to be a preset fifth angle.

[0051] Step S260: If the tube temperature of the indoor heat exchanger is within the fifth temperature range, the air guide angle of the first air guide plate is controlled to be a preset first angle, and the air guide angle of the second air guide plate is controlled to be a preset fifth angle.

[0052] Among them, the first temperature range>the second temperature range>the third temperature range>the fourth temperature range>the fifth temperature range, the preset first angle>the preset second angle>the preset third angle, and the preset fourth angle<the preset fifth angle.

[0053] In some embodiments, the third temperature range is 21° C. to 24° C. The preset third angle is the angle at which the first air guide plate directs the air outlet of the indoor unit toward the ceiling; the preset fourth angle is the angle when the second air guide plate is in a closed state.

[0054] When the temperature of the air conditioner's inner pipe is between 21℃ and 24℃, the possibility of the indoor unit producing odor is greatest. Therefore, during the refrigeration process and the process of the inner pipe heating up after the air conditioner is shut down, when the inner pipe temperature is between 21℃ and 24℃, the air outlet of the air conditioner is blown toward the ceiling by controlling the angles of the first air guide plate and the second air guide plate to avoid odor affecting the user.

[0055] The first temperature range is a range greater than 27°C, the second temperature range is 24°C to 27°C, the third temperature range is 21°C to 24°C, the fourth temperature range is 18°C ​​to 21°C, and the fifth temperature range is a range less than 18°C.

[0056] After the air conditioner is turned on for refrigeration, the tube temperature of the indoor heat exchanger gradually decreases. During the process of decreasing the tube temperature, the air guide angles of the first air guide plate and the second air guide plate are controlled according to the temperature range of the tube temperature.

[0057] When the tube temperature of the indoor heat exchanger is T>27℃, the first air guide plate is in Figure 3 The first air guide plate 6 is located at the position of the second air guide plate Figure 3 The second air guide plate 7 is positioned in the middle, and the indoor unit does not produce odor at this time, and the air conditioning air blows toward the area where the user is located.

[0058] When 24℃<T≤27℃, the first air guide plate is in Figure 3 The first air guide plate 5 is located at the position of the second air guide plate Figure 3 The second air guide plate 7 is positioned in the middle, and the indoor unit may produce odor at this time, so the air guide angle of the first air guide plate is reduced to make the air outlet of the air conditioner upward.

[0059] When 21℃<T≤24℃, the first air guide plate is in Figure 3 The first air guide plate 4 is located at the position of the second air guide plate Figure 3 The second air guide plate 7 is positioned in the middle, and the indoor unit is very likely to produce odor at this time, so the air outlet of the air conditioner is blown toward the ceiling to avoid the odor affecting the user.

[0060] When 18℃<T≤21℃, the first air guide plate is in Figure 3 The first air guide plate 5 is located at the position of the second air guide plate Figure 3 The second air guide plate 8 is positioned in the middle. At this time, the indoor unit may produce odor, so the air guide angle of the first air guide plate is reduced to make the air outlet of the air conditioner upward. At the same time, since the pipe temperature is low, for the sake of comfort and cooling effect, as well as anti-condensation considerations, the second air guide plate is opened to reduce the surface temperature difference of the first air guide plate, effectively alleviating the condensation of the first air guide plate.

[0061] When T<18℃, the first air guide plate is in Figure 3 The first air guide plate 6 is located at the position of the second air guide plate Figure 3 The second air guide plate 8 is in the middle position, and the indoor unit does not produce odor at this time, and the air conditioning blows to the area where the user is located. At the same time, since the pipe temperature is low, for the sake of comfort and cooling effect, as well as anti-condensation considerations, the second air guide plate is opened to reduce the surface temperature difference of the first air guide plate, effectively alleviating the condensation of the first air guide plate.

[0062] Other temperature ranges can also be set to correspond to the air guide angles of the air guide plates, as long as the following conditions are met: when 21°C<T≤24°C, the air guide angle of the first air guide plate is smaller, so that the air outlet of the air conditioner blows toward the ceiling; when the inner pipe temperature approaches 21°C~24°C, the air guide angle of the first air guide plate gradually decreases; when the inner pipe temperature is low and condensation may occur on the first air guide plate, condensation is reduced by controlling the air guide angle of the second air guide plate.

[0063] Optionally, after the air conditioner is turned on, if the user sets the air guide angle of the first air guide plate to gradually decrease when the temperature is 21℃ ~ 24℃ and the upper and lower air sweeping is fixed, the air guide angles of the first air guide plate and the second air guide plate are first controlled according to the tube temperature of the indoor heat exchanger, and then the air guide plates are adjusted to the fixed position set by the user.

[0064] In some embodiments, the further comprising: after the air conditioning refrigeration is started and after the air conditioning refrigeration is stopped, after each preset interval, the air guide angle of the first air guide plate and the air guide angle of the second air guide plate are controlled according to the tube temperature of the indoor heat exchanger.

[0065] In order to prevent the position of the air guide plate from changing after the machine is turned on, after the air conditioner is turned on for cooling, the air guide plate will first be moved to the corresponding position according to the inner tube temperature at the time of startup, and then the air guide angle of the air guide plate will be controlled once according to the inner tube temperature at a preset interval, such as 1 minute. For example, when the inner tube temperature is 30°C when the cooling machine is turned on, the air guide angle of the first air guide plate is the preset first angle, and the second air guide plate is closed. After 1 minute, the inner tube temperature is 22°C, and the air guide angle of the first air guide plate is controlled to the preset third angle, and the second air guide plate is closed. During this process, the air guide angle of the first air guide plate will not be moved to the preset second angle. Therefore, by setting the interval time for controlling the air guide angle of the air guide plate, it is prevented that the position of the air guide plate changes back and forth and affects the comfort.

[0066] When the air conditioner is turned on or has been turned on for a period of time, if the inner pipe temperature is less than 21°C and the current inner pipe temperature change rate is greater than 3°C / min, the position of the air guide plate can be changed according to the angle finally set by the user.

[0067] After the air conditioner is turned off, it is also necessary to control the angle of the air guide plate at a preset interval, that is, delay 1 minute after shutdown before controlling the angle of the air guide plate.

[0068] When the air conditioner is turned off, if the inner pipe temperature is greater than 21°C and the current inner pipe temperature change rate is greater than 3°C / min, the air guide plate can be directly closed without any further action.

[0069] In some embodiments, it also includes: after the air conditioning refrigeration is started and after the air conditioning refrigeration is stopped, and in the first preset interval time, if the tube temperature of the indoor heat exchanger is in a third temperature range, the air guide angle of the first air guide plate is controlled to be a preset third angle, and the air guide angle of the second air guide plate is controlled to be a preset fourth angle.

[0070] Since the air conditioner is likely to produce odor in the third temperature range, especially within 1 minute after the air conditioner is turned on, if the indoor heat exchanger tube temperature drops from high temperature to the third temperature range, the odor may be more serious at this time, so even if it is currently in the preset interval time, the air guide angle of the air guide plate must be controlled immediately. For example, after the air conditioner is turned on, the internal tube temperature is 30°C, and the air guide angle of the first air guide plate is the preset first angle. After that, the air guide angle of the first air guide plate should be controlled again after an interval of 1 minute. However, during this 1 minute, the internal tube temperature reaches 24°C. At this time, there is no need to wait for the end of 1 minute, and the air guide angle of the first air guide plate can be immediately controlled to the preset third angle.

[0071] Figure 4 FIG. 1 is a flow chart of a control method for starting the air conditioner refrigeration system of the present invention. Figure 4 As shown, the method includes:

[0072] Step 1: After turning on the air conditioner and turning on the cooling mode, check the pipe temperature of the indoor heat exchanger.

[0073] Step 2, if the inner tube temperature is ≤18℃, the first air guide plate and the second air guide plate are moved to the anti-odor position 1; if 18℃<inner tube temperature≤21℃, the first air guide plate and the second air guide plate are moved to the anti-odor position 2; if 21℃<inner tube temperature≤24℃, the first air guide plate and the second air guide plate are moved to the anti-odor position 3; if 24℃<inner tube temperature≤27℃, the first air guide plate and the second air guide plate are moved to the anti-odor position 4; if the inner tube temperature is>27℃, the first air guide plate and the second air guide plate are moved to the anti-odor position 5.

[0074] like Figure 3 As shown, the anti-odor position 1 is: the first air guide plate is position 6, and the second air guide plate is position 8.

The anti-odor position 4 is: the first air guide plate is position 5, and the second air guide plate is position 7. The anti-odor position 5 is: the first air guide plate is position 6, and the second air guide plate is position 7.

[0075] Figure 5 FIG. 1 is a flow chart of a control method after the air conditioner refrigeration is turned off according to the present invention. Figure 5 As shown, the method includes:

[0076] Step 11: After the air conditioner is turned off in cooling mode, the pipe temperature of the indoor heat exchanger is detected.

[0077] Step 12, if the inner tube temperature is ≤18°C, the first air guide plate and the second air guide plate are moved to the anti-odor position 7; if 18°C<inner tube temperature≤21°C, the first air guide plate and the second air guide plate are moved to the anti-odor position 8; if 21°C<inner tube temperature≤24°C, the first air guide plate and the second air guide plate are moved to the anti-odor position 9; if 24°C<inner tube temperature≤27°C, the first air guide plate and the second air guide plate are moved to the anti-odor position 10; if the inner tube temperature is >27°C, the first air guide plate and the second air guide plate are moved to the anti-odor position 11.

[0078] like Figure 3 As shown, the anti-odor position 7 is: the first air guide plate is at position 6, and the second air guide plate is at position 8. The anti-odor position 8 is: the first air guide plate is at position 5, and the second air guide plate is at position 8. The anti-odor position 9 is: the first air guide plate is at position 4, and the second air guide plate is at position 7. The anti-odor position 10 is: the first air guide plate is at position 5, and the second air guide plate is at position 7. The anti-odor position 11 is: the first air guide plate is at position 6, and the second air guide plate is at position 7.

[0079] By adopting the technical solution of this embodiment, a first air guide plate and a second air guide plate are provided at the air outlet of the indoor unit of the air conditioner; after the air conditioner is turned on and stopped, the air guide angle of the first air guide plate and the air guide angle of the second air guide plate are controlled according to the pipe temperature of the indoor heat exchanger. Thus, by controlling the angle of the air guide plate after the air conditioner is turned on and stopped, the air outlet is blown toward the ceiling at the pipe temperature moment when odor may be generated, thereby avoiding the odor from affecting the user and improving the user experience.

[0080] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided.

The first air guide plate is opened around the rotating axis toward the outside of the indoor unit, and the second air guide plate is opened around the rotating axis toward the inside of the indoor unit.

[0082] The three preset wind guide angles of the first wind guide plate include: a preset first angle, a preset second angle, and a preset third angle. Figure 3 In the figure, the first angle is preset to be the angle shown by the first air guide plate 6, the second angle is preset to be the angle shown by the first air guide plate 5, and the third angle is preset to be the angle shown by the first air guide plate 4.

[0083] The angle of the first air guide plate when closed is 0°, and the greater the opening range of the first air guide plate is, the greater the air guide angle is, and therefore the preset first angle>the preset second angle>the preset third angle.

[0084] Optionally, the preset range of the first wind guide angle is 40° to 50°, the preset range of the second wind guide angle is 30° to 40°, and the preset range of the third angle is 20° to 30°.

[0085] The second air guide plate has two preset air guide angles including: a preset fourth angle and a preset fifth angle. Figure 3 In the embodiment, the fourth angle is preset to be the angle shown by the second air guide plate 7, and the fifth angle is preset to be the angle shown by the second air guide plate 8.

[0086] The angle of the second air guide plate when closed is 0°, and the greater the opening amplitude of the second air guide plate is, the greater the air guide angle is, and therefore the preset fourth angle is less than the preset fifth angle.

[0087] Optionally, the fourth angle is preset to 0°, ie, the second air guide plate is closed, and the fifth angle is preset to range from 20° to 30°.

[0088] See also Figure 2 The schematic diagram of the structure of an embodiment of the device of the present invention is shown. The control device of the air conditioner may include: an acquisition unit 102 and a control power supply 104.

[0089] The acquisition unit 102 is configured to acquire the pipe temperature of the indoor heat exchanger after the air conditioner is turned on and after the air conditioner is turned off. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0090] The air conditioner will produce odor in heating mode, and after the cooling mode is stopped, the internal fan will not stop running immediately, and the air guide plate will not close immediately. The air conditioner will still blow out residual cold, which will also produce odor. Therefore, odor removal is required during the cooling operation of the air conditioner and after the cooling mode is stopped.

[0091] The control unit 104 is configured to control the air guide angle of the first air guide plate and the air guide angle of the second air guide plate according to the tube temperature of the indoor heat exchanger. The specific functions and processing of the control unit 104 refer to step S120.

[0092] This solution controls the angle of the air guide plate when the air conditioner is turned on or off. Without increasing the equipment manufacturing cost, it blows the air toward the ceiling at the pipe temperature when odor may be generated, instead of directly toward the user area, thereby alleviating the impact of odor from the air conditioner indoor unit on the user.

[0093] In some embodiments, the control unit 104 controls the air guide angle of the first air guide plate and the air guide angle of the second air guide plate according to the tube temperature of the indoor heat exchanger, including:

[0094] The control unit 104 is further specifically configured to determine a temperature range in which the tube temperature of the indoor heat exchanger is located, including a first temperature range, a second temperature range, a third temperature range, a fourth temperature range, and a fifth temperature range.

[0095] The control unit 104 is further specifically configured to control the air guide angle of the first air guide plate to be a preset first angle and the air guide angle of the second air guide plate to be a preset fourth angle if the tube temperature of the indoor heat exchanger is within a first temperature range.

[0096] The control unit 104 is further configured to control the air guide angle of the first air guide plate to be a preset second angle and the air guide angle of the second air guide plate to be a preset fourth angle if the tube temperature of the indoor heat exchanger is within the second temperature range.

[0097] The control unit 104 is further specifically configured to control the air guide angle of the first air guide plate to be a preset third angle and the air guide angle of the second air guide plate to be a preset fourth angle if the tube temperature of the indoor heat exchanger is within a third temperature range.

[0098] The control unit 104 is further specifically configured to control the air guide angle of the first air guide plate to be a preset second angle and the air guide angle of the second air guide plate to be a preset fifth angle if the tube temperature of the indoor heat exchanger is within a fourth temperature range.

[0099] The control unit 104 is further specifically configured to control the air guide angle of the first air guide plate to be a preset first angle and the air guide angle of the second air guide plate to be a preset fifth angle if the tube temperature of the indoor heat exchanger is within the fifth temperature range.

[0100] Among them, the first temperature range>the second temperature range>the third temperature range>the fourth temperature range>the fifth temperature range, the preset first angle>the preset second angle>the preset third angle, and the preset fourth angle<the preset fifth angle.

[0101] In some embodiments, the third temperature range is 21° C. to 24° C. The preset third angle is the angle at which the first air guide plate directs the air outlet of the indoor unit toward the ceiling; the preset fourth angle is the angle when the second air guide plate is in a closed state.

[0102] When the temperature of the air conditioner's inner pipe is between 21℃ and 24℃, the possibility of the indoor unit producing odor is greatest. Therefore, during the refrigeration process and the process of the inner pipe heating up after the air conditioner is shut down, when the inner pipe temperature is between 21℃ and 24℃, the air outlet of the air conditioner is blown toward the ceiling by controlling the angles of the first air guide plate and the second air guide plate to avoid odor affecting the user.

[0103] The first temperature range is a range greater than 27°C, the second temperature range is 24°C to 27°C, the third temperature range is 21°C to 24°C, the fourth temperature range is 18°C ​​to 21°C, and the fifth temperature range is a range less than 18°C.

[0104] After the air conditioner is turned on for refrigeration, the tube temperature of the indoor heat exchanger gradually decreases. During the process of decreasing the tube temperature, the air guide angles of the first air guide plate and the second air guide plate are controlled according to the temperature range of the tube temperature.

[0105] When the tube temperature of the indoor heat exchanger is T>27℃, the first air guide plate is in Figure 3 The first air guide plate 6 is located at the position of the second air guide plate Figure 3 The second air guide plate 7 is positioned in the middle, and the indoor unit does not produce odor at this time, and the air conditioning air blows toward the area where the user is located.

[0106] When 24℃<T≤27℃, the first air guide plate is in Figure 3 The first air guide plate 5 is located at the position of the second air guide plate Figure 3 The second air guide plate 7 is positioned in the middle, and the indoor unit may produce odor at this time, so the air guide angle of the first air guide plate is reduced to make the air outlet of the air conditioner upward.

[0107] When 21℃<T≤24℃, the first air guide plate is in Figure 3 The first air guide plate 4 is located at the position of the second air guide plate Figure 3 The second air guide plate 7 is positioned in the middle, and the indoor unit is very likely to produce odor at this time, so the air outlet of the air conditioner is blown toward the ceiling to avoid the odor affecting the user.

[0108] When 18℃<T≤21℃, the first air guide plate is in Figure 3 The first air guide plate 5 is located at the position of the second air guide plate Figure 3The second air guide plate 8 is positioned in the middle. At this time, the indoor unit may produce odor, so the air guide angle of the first air guide plate is reduced to make the air outlet of the air conditioner upward. At the same time, since the pipe temperature is low, for the sake of comfort and cooling effect, as well as anti-condensation considerations, the second air guide plate is opened to reduce the surface temperature difference of the first air guide plate, effectively alleviating the condensation of the first air guide plate.

[0109] When T<18℃, the first air guide plate is in Figure 3 The first air guide plate 6 is located at the position of the second air guide plate Figure 3 The second air guide plate 8 is in the middle position, and the indoor unit does not produce odor at this time, and the air conditioning blows to the area where the user is located. At the same time, since the pipe temperature is low, for the sake of comfort and cooling effect, as well as anti-condensation considerations, the second air guide plate is opened to reduce the surface temperature difference of the first air guide plate, effectively alleviating the condensation of the first air guide plate.

[0110] Other temperature ranges can also be set to correspond to the air guide angles of the air guide plates, as long as the following conditions are met: when 21°C<T≤24°C, the air guide angle of the first air guide plate is smaller, so that the air outlet of the air conditioner blows toward the ceiling; when the inner pipe temperature approaches 21°C~24°C, the air guide angle of the first air guide plate gradually decreases; when the inner pipe temperature is low and condensation may occur on the first air guide plate, condensation is reduced by controlling the air guide angle of the second air guide plate.

[0111] Optionally, after the air conditioner is turned on, if the user sets the air guide angle of the first air guide plate to gradually decrease when the temperature is 21℃ ~ 24℃ and the upper and lower air sweeping is fixed, the air guide angles of the first air guide plate and the second air guide plate are first controlled according to the tube temperature of the indoor heat exchanger, and then the air guide plates are adjusted to the fixed position set by the user.

[0112] In some embodiments, the control unit 104 is further configured to: after the air conditioning refrigeration is started and after the air conditioning refrigeration is stopped, after a preset interval time has passed, control the air guide angle of the first air guide plate and the air guide angle of the second air guide plate according to the tube temperature of the indoor heat exchanger.

[0113] In order to prevent the position of the air guide plate from changing after the machine is turned on, after the air conditioner is turned on for cooling, the air guide plate will first be moved to the corresponding position according to the inner tube temperature at the time of startup, and then the air guide angle of the air guide plate will be controlled once according to the inner tube temperature at a preset interval, such as 1 minute. For example, when the inner tube temperature is 30°C when the cooling machine is turned on, the air guide angle of the first air guide plate is the preset first angle, and the second air guide plate is closed. After 1 minute, the inner tube temperature is 22°C, and the air guide angle of the first air guide plate is controlled to the preset third angle, and the second air guide plate is closed. During this process, the air guide angle of the first air guide plate will not be moved to the preset second angle. Therefore, by setting the interval time for controlling the air guide angle of the air guide plate, it is prevented that the position of the air guide plate changes back and forth and affects the comfort.

[0114] When the air conditioner is turned on or has been turned on for a period of time, if the inner pipe temperature is less than 21°C and the current inner pipe temperature change rate is greater than 3°C / min, the position of the air guide plate can be changed according to the angle finally set by the user.

[0115] After the air conditioner is turned off, the angle of the air guide plate needs to be controlled once at a preset interval, that is, the angle of the air guide plate should be controlled after a delay of 1 minute after shutdown.

[0116] When the air conditioner is turned off, if the inner pipe temperature is greater than 21°C and the current inner pipe temperature change rate is greater than 3°C / min, the air guide plate can be directly closed without any further action.

[0117] In some embodiments, the control unit 104 is further configured to: after the air conditioning refrigeration is started and after the air conditioning refrigeration is stopped, and in the first preset interval time, if the tube temperature of the indoor heat exchanger is in a third temperature range, control the air guide angle of the first air guide plate to be a preset third angle, and control the air guide angle of the second air guide plate to be a preset fourth angle.

[0118] Since the air conditioner is likely to produce odor in the third temperature range, especially within 1 minute after the air conditioner is turned on, if the indoor heat exchanger tube temperature drops from high temperature to the third temperature range, the odor may be more serious at this time, so even if it is currently in the preset interval time, the air guide angle of the air guide plate must be controlled immediately. For example, after the air conditioner is turned on, the internal tube temperature is 30°C, and the air guide angle of the first air guide plate is the preset first angle. After that, the air guide angle of the first air guide plate should be controlled again after an interval of 1 minute. However, during this 1 minute, the internal tube temperature reaches 24°C. At this time, there is no need to wait for the end of 1 minute, and the air guide angle of the first air guide plate can be immediately controlled to the preset third angle.

The anti-odor position 8 is: the first air guide plate is at position 5, and the second air guide plate is at position 8. The anti-odor position 9 is: the first air guide plate is at position 4, and the second air guide plate is at position 7. The anti-odor position 10 is: the first air guide plate is at position 5, and the second air guide plate is at position 7.
