Description

Technical Field

[0001] This invention relates to the field of home appliances, and in particular to a control method for an air conditioner and an air conditioner. Background Technology

[0002] In household air conditioners, the automatic oscillation function of the air outlet deflector is a very common feature. In summer, users often choose to turn on the automatic oscillation function of the air conditioner deflector if they want to increase the air supply coverage area so that multiple users in different parts of the room can enjoy the comfortable cool air from the air conditioner, or if they want to cool the room evenly.

[0003] In existing air conditioner control methods, the air deflector is typically set to oscillate at a constant speed, and generally operates by continuously oscillating up and down or left and right. This allows the air conditioner to distribute the airflow carrying cooling or heating energy evenly throughout the room. Current technology considers this oscillation method of the air deflector to be the optimal one, maximizing the uniformity of room temperature. Summary of the Invention

[0004] Based on the above background, one objective of the present invention is to provide a control method for an air conditioner with better uniform temperature regulation.

[0005] Another objective of the present invention is to provide an air conditioner that solves the above-mentioned problems.

[0006] In particular, according to a first aspect of the present invention, the present invention provides a control method for an air conditioner, wherein a first air guide assembly is provided at the indoor air outlet of the air conditioner, the first air guide assembly is used to adjust the longitudinal air outlet direction of the indoor air outlet, and has multiple preset working positions.

[0007] The control method for the air conditioner includes: acquiring the air supply mode and operating mode of the air conditioner; determining whether the air supply mode is a preset reciprocating air supply mode; if so, determining the preset dwell time of the first air guide component at each working position according to the operating mode; controlling the first air guide component to oscillate back and forth, and to stay at each working position for the corresponding preset dwell time.

[0008] Optionally, a second air guide component is also provided at the indoor air outlet, which is used to adjust the lateral air outlet direction.

[0009] The control method for the air conditioner also includes: controlling the second air guide component to swing back and forth once within each preset dwell time of the first air guide component; and the time for the second air guide component to swing back and forth once is equal to the preset dwell time.

[0010] Optionally, the step of controlling the second air guide assembly to oscillate once is configured to: control the second air guide assembly to oscillate at a constant speed during the oscillation process.

[0011] Optionally, the air conditioner's operating modes include cooling mode and heating mode.

[0012] The steps for determining the preset residence time of the first air guide component at each working position, based on the operating mode, include:

[0013] When the operating mode is cooling mode, the preset dwell time is set as follows: the higher the air outlet height corresponding to the working position, the longer the corresponding preset dwell time.

[0014] When the operating mode is heating mode, the preset dwell time is set as follows: the lower the air outlet height corresponding to the working position, the longer the preset dwell time.

[0015] Optionally, when the operating mode is cooling mode, the step of determining the preset dwell time of the first air guide component at each working position includes: obtaining the preset dwell time of the first air guide component at the working position with the lowest air outlet height; and obtaining the preset dwell time of the first air guide component at other working positions based on the number of working positions between other working positions and the working position with the lowest air outlet height and the preset dwell time of the first air guide component at the working position with the lowest air outlet height.

[0016] Optionally, when the operating mode is heating mode, the step of determining the preset dwell time of the first air guide component at each working position includes: obtaining the preset dwell time of the first air guide component at the working position with the highest air outlet height; and obtaining the preset dwell time of the first air guide component at other working positions based on the number of working positions between other working positions and the working position with the highest air outlet height and the preset dwell time of the first air guide component at the working position with the highest air outlet height.

[0017] Optionally, the first air guide assembly has the same swing angle between any two adjacent working positions.

[0018] Optionally, the air conditioner also includes a compressor.

[0019] When the air supply mode is a preset reciprocating air supply mode, the control method of the air conditioner also includes: adjusting the operating frequency of the compressor according to the preset dwell time of the first air guide component in the working position.

[0020] Optionally, the operating frequency can be set to increase as the preset dwell time increases.

[0021] According to another aspect of the present invention, an air conditioner is provided, comprising a first air guide assembly and a control device. The first air guide assembly is disposed at the indoor air outlet of the air conditioner. The control device includes a processor and a memory, wherein the memory stores a control program, and the control program, when executed by the processor, is used to implement the control method of any of the above-described air conditioners.

[0022] The first air guide component of the air conditioner of the present invention is disposed at the indoor air outlet for adjusting the longitudinal air outlet direction and has multiple preset working positions. According to the air conditioner control method of the present invention, the air conditioner can adjust the preset dwell time of the first air guide component at each working position according to the operating mode during reciprocating air supply. This allows the air conditioner to selectively keep the first air guide component at a specific position for a longer time under different operating modes, thereby increasing the air volume at that position and improving the uniform temperature regulation effect of the air conditioner throughout the room.

[0023] Furthermore, the air conditioner also has a second air guide assembly that can oscillate in coordination with the first air guide assembly. In addition, when operating in cooling mode, by controlling the first air guide assembly, the air conditioner can deliver more cooling energy to relatively higher areas of the room and areas farther from the air outlet; when operating in heating mode, by controlling the first air guide assembly, the air conditioner can deliver more heat to relatively lower areas of the room, resulting in better uniform temperature control throughout the room.

[0036] Figure 1 This is a schematic cross-sectional view of an air conditioner 10 according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the first air guide assembly 12 of the air conditioner 10 shown.

[0037] refer to Figure 1As shown, in this embodiment, the air conditioner 10 has a first air guide assembly 12 at its indoor air outlet. The first air guide assembly 12 is used to adjust the longitudinal air outlet direction and has multiple preset working positions. For example, in some optional embodiments, such as... Figure 2 As shown by the dotted lines, the first air guide assembly 12 has a total of 6 working positions, including H0 to H5, so that the air outlet can have 6 corresponding longitudinal air outlet directions with different air outlet heights when it is open. When the first air guide assembly 12 swings to the working position H0, the longitudinal air outlet direction tends to be downward and the air outlet height is the lowest; when the first air guide assembly 12 swings to the working position H5, the longitudinal air outlet direction tends to be upward and the air outlet height is the highest.

[0038] In some optional embodiments, the swing angle between any two adjacent working positions of the first air guide assembly 12 is equal, that is, the rotation angle required for the first air guide assembly 12 to swing from one working position to the next is equal each time. For example, in Figure 2 In the embodiment shown, the swing angle is set to 15°, so that the first air guide assembly 12 needs to swing 5 times and rotate 75° from the working position H0 to H5.

[0039] It should be noted that the number of working positions of the first air guide assembly 12, as well as the swing angle between any two adjacent working positions of the first air guide assembly 12, can be adjusted accordingly based on the air outlet of the air conditioner 10. Meanwhile, although... Figure 1 In the embodiment shown, the first air guide assembly 12 of the air conditioner 10 includes only one air guide plate as shown in the figure. However, it is understood that in other embodiments, the first air guide assembly 12 may also include two or more air guide plates, which is not limited here.

[0040] Figure 3 This is a flowchart illustrating a control method for an air conditioner 10 according to an embodiment of the present invention.

[0041] refer to Figure 3 As shown, the control method of the air conditioner 10 generally includes:

[0042] Step S302: Obtain the air supply mode and operating mode of the air conditioner 10;

[0043] Step S304: Determine whether the air supply mode is the preset reciprocating air supply mode;

[0044] Step S306: If yes, determine the preset dwell time of the first air guide component 12 at each working position according to the operating mode;

[0045] Step S308: Control the first air guide component 12 to swing back and forth, and stay at each working position for a corresponding preset dwell time.

[0046] The air conditioner 10 can be preset with multiple air supply modes, including a reciprocating air supply mode in which the first air guide component 12 oscillates back and forth between its working positions. In some optional embodiments, a second air guide component 14 is also provided at the indoor air outlet. The second air guide component 14 is used to adjust the lateral air outlet direction of the indoor air outlet. In this case, the reciprocating air supply mode also includes the reciprocating oscillation of the second air guide component 14.

[0047] The air conditioner 10 has two operating modes: cooling mode and heating mode. In cooling mode, the air conditioner 10 blows cooling air into the room from the air outlet to cool the room. In heating mode, the air conditioner 10 blows heating air into the room from the air outlet to raise the room temperature.

[0048] Based on the control method of the air conditioner 10 in the above embodiment, the first air guide component 12 will stay at each working position for a corresponding preset dwell time during the reciprocating swing process. That is to say, the preset dwell time of the first air guide component 12 is different according to the different air outlet height, so that the air conditioner 10 can fully deliver air to the room at a specific air outlet height. Specifically, for the two working modes of the air conditioner 10, namely cooling mode and heating mode, the swing mode of the first air guide component 12 is adjusted in a targeted manner for each working mode.

[0049] In existing air conditioner control methods, the air deflector is typically set to oscillate at a constant speed, and generally operates by continuously reciprocating up and down or left and right. This allows the air conditioner to distribute the airflow carrying cooling or heating energy evenly throughout the room. Current technology considers this uniform, continuous reciprocating oscillation of the air deflector to be the optimal oscillation method, maximizing the uniform temperature control within the room.

[0050] However, the present invention creatively overcomes this technical bias by setting the first air guide component 12 to stay at a predetermined dwell time for each swing to a working position. In this way, the predetermined dwell time of the first air guide component 12 at a specific working position is extended or shortened in a targeted manner according to the operating mode of the air conditioner 10. As a result, the indoor air outlet of the air conditioner 10 no longer blows the airflow into the room in a uniform manner, but instead increases or decreases the airflow at a specific air outlet height in a targeted manner.

[0051] Generally, when an air conditioner is running in cooling mode, it indicates that the room temperature is relatively high, so the user needs the air conditioner to cool the room. The opposite is true when the air conditioner is running in heating mode. Due to the difference in density between cold and hot air, when cold and hot air meet, the cold air sinks and the hot air rises. For air conditioners with a uniformly oscillating air deflector, when running in cooling mode, although the airflow carrying cold air appears to be evenly distributed from the vents, most of the cold air sinks and accumulates near the vents in the overall room. This is one of the reasons why, even when the airflow is in vertical swing mode, the temperature near the vents is much lower than the temperature further away.

[0052] When this type of air conditioner is running in heating mode, although the airflow carrying heat is evenly blown outwards from the vents, the overall cool air in the room remains concentrated at a lower altitude, while the heat continues to rise. The airflow from the air conditioner cannot effectively disperse or heat the cool air at a lower altitude. Furthermore, since users often sit or lie in a lower position in the room, the intermittent flow of hot air and the cool air pushed back after the hot air passes create alternating hot and cold convection currents. Before the air is fully heated, the user experience may actually be worse than if the heating mode were not turned on.

[0053] Recognizing that while existing technologies can theoretically achieve uniform room temperature regulation, the actual effect is not ideal, this embodiment creatively departs from the traditional method of controlling the first air guide component 12 through continuous reciprocating oscillation. Instead, it sets the first air guide component 12 to pause for a preset duration at each working position after oscillation. Furthermore, depending on the different environments encountered in cooling and heating modes, the preset dwell time of the first air guide component 12 at specific working positions is extended or shortened accordingly. This allows the airflow at the indoor air outlet of the air conditioner 10 to be increased or decreased at specific outlet heights. Because this embodiment controls the first air guide component 12 according to different operating modes, regardless of whether the operating mode is cooling or heating, the air conditioner 10 can deliver air more effectively at specific outlet heights, resulting in better uniform temperature regulation across different areas of the room at varying distances from the air conditioner 10.

[0054] Figure 1 The diagram also illustrates the second air guide component 14. The second air guide component 14 can swing left and right within a preset range, thereby adjusting the lateral airflow direction of the air outlet. It can be understood that... Figure 1 Although only a portion of the second air guide assembly 14, namely one of its blades, can be shown, in Figure 1In the embodiment shown, multiple second air guide components 14 can be arranged side by side along the length of the air outlet. Figure 1 The oscillating blades are shown, and the horizontal airflow direction of the air outlet is adjusted accordingly.

[0055] When the air supply method is determined to be reciprocating air supply, the air conditioner 10 determines the preset dwell time of the first air guide component 12 at each working position according to the operating mode. During the reciprocating air supply, the first air guide component 12 will continuously oscillate up and down, for example, in... Figure 2 In the illustrated embodiment, the airflow gradually swings from working position H0 to H5, then from working position H5 back to H0, and this cycle repeats. When the first air guide component 12 swings from the previous working position to the current working position, it will remain at the current working position for a preset duration. Depending on the operating mode of the air conditioner 10, the preset duration of the first air guide component 12 at the same working position is usually different, and also, under the same operating mode, the preset duration of the first air guide component 12 at different working positions is usually different.

[0056] In embodiments where a second air guide assembly 14 is also provided at the indoor air outlet, the second air guide assembly 14 will also swing in coordination with the first air guide assembly 12, as shown in the reference. Figure 4 As shown, the control method of the air conditioner 10 at this time includes:

[0057] Step S402: Obtain the air supply mode and operating mode of the air conditioner 10;

[0058] Step S404: Determine whether the air supply mode is the preset reciprocating air supply mode;

[0059] Step S406: If yes, determine the preset dwell time of the first air guide assembly 12 at each working position according to the operating mode;

[0060] Step S408: Control the first air guide component 12 to swing back and forth, and stay at each working position for a corresponding preset dwell time.

[0061] In step S410, within each preset dwell time of the first air guide component 12, the second air guide component 14 is controlled to swing back and forth once; and the time for the second air guide component 14 to swing back and forth once is equal to the preset dwell time.

[0062] The first air guide component 12 oscillates back and forth between working positions. Simply put, it oscillates from one working position to the next, then stays at that position for a preset duration, during which time the air conditioner 10 maintains this air outlet height and continues to blow air. After the preset duration ends, the first air guide component 12 oscillates to the next working position and repeats this process (the air conditioner 10 continues to blow air during the oscillation of the first air guide component 12). In the above embodiment, when the first air guide component 12 oscillates to a working position and stays there, the second air guide component 14 begins to oscillate and oscillates back and forth once. Specifically, the first air guide component 12 and the second air guide component 14 do not oscillate simultaneously; that is, the second air guide component 14 begins to oscillate at the same time the first air guide component 12 oscillates to a working position. Since the time it takes for the second air guide component 14 to oscillate once is equal to the preset duration corresponding to the current working position to which the first air guide component 12 oscillates, the first air guide component 12 begins to oscillate to the next working position as the second air guide component 14 ends its oscillation.

[0063] Because the preset dwell time of the first air guide component 12 varies at different working positions, the time for the second air guide component 14 to complete one reciprocating swing also varies. However, regardless of the preset dwell time, the second air guide component 14 preferably swings at a uniform speed during the reciprocating swing process. That is, during the same reciprocating swing process, the angle of the second air guide component 14 swinging within the same duration is equal. Specifically, in some optional embodiments, the second air guide component 14 is driven by a motor capable of bidirectional rotation. When the second air guide component 14 swings to its leftmost or rightmost end, the motor needs to stop and switch its rotation direction. The uniform speed swing of the second air guide component 14 during the reciprocating swing process means that, excluding this special case, the process of the second air guide component 14 swinging from one end to the other preferably swings at a uniform speed.

[0064] The second air guide assembly 14 typically has a preset initial position. Each time, the second air guide assembly 14 swings from this initial position and returns to its initial position after one complete swing. In some optional embodiments, the initial position of the second air guide assembly 14 is a position perpendicular to the air outlet, or a position that directs the airflow directly in front of the air outlet of the air conditioner 10. This initial position is usually located in the middle of the left-right swing range of the second air guide assembly 14. One complete swing of the second air guide assembly 14 means that the second air guide assembly 14 swings from its initial position to one end of the swing range, then to the other end, and finally back to its initial position.

[0065] In a further embodiment with the second air guide assembly 14, the second air guide assembly 14 oscillates back and forth once while the first air guide assembly 12 is in the working position, causing the air conditioner 10 to sweep air left and right once, effectively increasing the lateral air supply area of ​​the air conditioner 10 and further improving the uniform temperature regulation effect of the air conditioner 10 throughout the room. Since the second air guide assembly 14 oscillates back and forth once when the first air guide assembly 12 is in each working position, the air conditioner 10 can sweep air left and right once at each air outlet height, eliminating situations where the air conditioner 10 fails to sweep air left and right at a certain air outlet height or fails to sweep air to one side, thus avoiding dead zones in the room.

[0066] The air conditioner 10 has two operating modes: cooling mode and heating mode. Depending on the operating mode, the preset dwell time of the first air guide component 12 at the working position also varies. Specifically:

[0067] When the operating mode is cooling mode, the preset dwell time is set as follows: the higher the air outlet height corresponding to the working position, the longer the preset dwell time.

[0068] When the operating mode is heating mode, the preset dwell time is set as follows: the lower the air outlet height corresponding to the working position, the longer the preset dwell time.

[0069] When an air conditioner is running in cooling mode, the temperature of the cooling air blown out from the air conditioner's vent is often lower than the temperature inside the room. Since cold air is heavier than hot air, the amount of cold air carried by the cooling air will accumulate more in the lower part of the room near the air conditioner's vent, resulting in poor cooling effect in areas far from the air conditioner. At the same time, higher areas in the room cannot be cooled down well.

[0070] To overcome this problem, in some optional embodiments, the preset dwell time is set such that the higher the air outlet height corresponding to the working position, the longer the preset dwell time. Thus, during one complete reciprocating swing of the first air guide assembly 12, the first air guide assembly 12 can remain at the working position at a higher air outlet height for a longer period. During this time, the air conditioner 10 can blow more cooling airflow to higher and farther locations in the room, ensuring that the higher areas of the room where hot air accumulates and the farther areas of the room where sufficient cooling is difficult to receive are adequately cooled, thereby achieving uniform cooling throughout the room. Furthermore, because the preset dwell time of the first air guide assembly 12 at the working position at a lower air outlet height is shorter, it will not cause excessive accumulation of cold air near the air outlet area of ​​the air conditioner 10, thus preventing excessive temperature differences throughout the room.

[0071] With the operating mode set to cooling mode, the preset dwell time of the first air guide component 12 at each working position can be determined in the following way:

[0072] Obtain the preset dwell time of the first air guide component 12 at the working position with the lowest air outlet height; based on the number of working positions between other working positions and the working position with the lowest air outlet height and the preset dwell time of the first air guide component 12 at the working position with the lowest air outlet height, obtain the preset dwell time of the first air guide component 12 at other working positions.

[0073] In other words, the preset dwell time of the first air guide component 12 at the working position with the lowest air outlet height can be used as the base value, and the preset dwell time of other working positions can be determined by adding a certain value based on the number of working positions between other working positions and the working position with the lowest air outlet height.

[0074] For example, in some optional implementations, the preset dwell time at each work location can be calculated in the following manner:

[0075] Obtain the preset dwell time T0 of the first air guide component 12 at the working position H0 with the lowest air outlet height; calculate the dwell time T0 of the first air guide component 12 at other working positions H n Preset dwell time T n T n =T0+nT s .

[0076] In the formula, n represents the swing from the lowest working position H0 at the air outlet height to the current working position H. n The required number of oscillations, for example, H1 indicates that one oscillation is required to move from working position H0 to working position H1 (only for unidirectional oscillations from the working position with the lowest air outlet height to the working position with the highest air outlet height), t s This is the preset delay time.

[0077] The preset delay time causes the preset dwell time of the first air guide component 12 at the working position to gradually increase as the air outlet height increases. The preset delay time can also be set and adjusted accordingly based on the number of preset working positions of the air conditioner 10. For example, when there are 6 preset working positions, the preset delay time can be set to 0.5 seconds, 1 second, 1.5 seconds, or 2 seconds, etc., so that the preset dwell time of the first air guide component 12 at the working position with the highest air outlet height can be extended by 2.5 to 10 seconds compared to the preset dwell time at the working position with the lowest air outlet height. In some optional embodiments, the preset dwell time of the first air guide component 12 at the working position H0 with the lowest air outlet height can be set to 5 seconds. Therefore, when there are 6 preset working positions and the preset delay time is set to 1 second, the preset dwell time of the first air guide component 12 at the working position H5 with the highest air outlet height is 10 seconds.

[0078] In some other alternative implementations, the preset dwell time at each work location can also be calculated in other ways, for example, at other work locations H n Preset dwell time T n Set to n+1 times the preset dwell time T0 at the lowest working position H0 at the air outlet height (T n =(n+1)T0), etc.

[0079] In addition, the preset dwell time of the first air guide assembly 12 at the working position with the highest air outlet height can be significantly longer than the preset dwell time at the working position with the lowest air outlet height, while the preset dwell time at the working position in between can be slightly longer than the preset dwell time at the working position with the lowest air outlet height (T). n-1 =T0+(n-1)T s T n =T0+T q T q Much greater than (n-1)T s ).

[0080] The above-described calculation method for calculating the preset dwell time at each working position is only one embodiment of the present invention and does not include a specific limitation on the calculation method for the preset dwell time. Furthermore, defining the working position with the lowest air outlet height of the first air guide assembly 12 as H0 and obtaining the preset dwell time T0 as the benchmark for calculating the preset dwell time at each working position is one of the optional implementation methods and should not be construed as including a limitation on the present invention. For example, those skilled in the art can also define the working position with the highest air outlet height of the first air guide assembly 12 as H0 and obtain the preset dwell time T0, and simply make corresponding adjustments to the calculation method to obtain the same effect as the above calculation formula.

[0081] When an air conditioner is running in heating mode, the temperature of the heated airflow blown out of the air conditioner's vent is often higher than the temperature inside the room. Since hot air is lighter than cold air, the heat carried by the heated airflow will accumulate more in the higher parts of the room, causing users sitting or lying in lower positions to be surrounded by cold air. At the same time, the convection caused by the intermittent blowing of the heated airflow will also cause users to experience alternating periods of hot and cold, resulting in a poor experience.

[0082] To overcome this problem, in some optional embodiments, the preset dwell time is set such that the lower the air outlet height corresponding to the working position, the longer the preset dwell time. Thus, during one complete reciprocating oscillation of the first air guide assembly 12, the first air guide assembly 12 can remain at the working position with a lower air outlet height for a longer period. During this time, the air conditioner 10 can better deliver heating airflow to the lower part of the room where the user is located, not only dispersing the cold air around the user but also heating the air at the lower part of the room more quickly, causing the overall temperature in the room to rise faster.

[0083] With the operating mode set to heating mode, the preset dwell time of the first air guide assembly 12 at each working position can be determined in the following way:

[0084] Obtain the preset dwell time of the first air guide component 12 at the working position with the highest air outlet height; based on the number of working positions between other working positions and the working position with the highest air outlet height and the preset dwell time of the first air guide component 12 at the working position with the highest air outlet height, obtain the preset dwell time of the first air guide component 12 at other working positions.

[0085] In other words, the preset dwell time of the first air guide component 12 at the working position with the highest air outlet height can be used as the base value, and the preset dwell time of other working positions can be determined by adding a certain value based on the number of working positions between other working positions and the working position with the highest air outlet height.

[0086] The calculation method for the preset dwell time of each working position in heating mode is similar to that in cooling mode. The main difference lies in the different benchmarks used to calculate the preset dwell time of each working position, so it will not be elaborated here. It is also understood that using the preset dwell time of the first air guide assembly 12 at the working position with the highest air outlet height as the benchmark for calculating the preset dwell time of each working position is one of the optional implementation methods and should not be construed as limiting the present invention.

[0087] In addition to the above-described embodiments that control the first air guide assembly 12 and the second air guide assembly 14, in some alternative embodiments, the uniform temperature regulation effect of the air conditioner 10 can be further improved by combining the control of the compressor 16 of the air conditioner 10, while reducing the energy consumption of the air conditioner 10.

[0088] Specifically, the operating frequency of the compressor 16 is adjusted according to the preset dwell time of the first air guide assembly 12 in the working position, and the operating frequency of the compressor 16 increases as the preset dwell time of the first air guide assembly 12 increases. In other words, when the first air guide assembly 12 swings from one working position to the next working position with a longer preset dwell time, the operating frequency of the compressor 16 increases accordingly. It can be understood that when the first air guide assembly 12 swings from one working position to the next working position with a shorter preset dwell time, the operating frequency of the compressor 16 will decrease accordingly, even though the operating frequency of the compressor 16 still decreases as the preset dwell time of the first air guide assembly 12 decreases.

[0089] When the first air guide assembly 12 is in a working position with a relatively longer preset dwell time, it indicates that the indoor air outlet of the air conditioner 10 is at an air outlet height that requires more cooling or heating. Therefore, the operating frequency of the compressor 16 is increased simultaneously to meet the cooling or heating needs of the air conditioner 10. Conversely, when the first air guide assembly 12 is in a working position with a relatively shorter preset dwell time, it indicates that the indoor air outlet of the air conditioner 10 is at an air outlet height that requires less cooling or heating. Therefore, the operating frequency of the compressor 16 can be reduced accordingly to lower the energy consumption of the air conditioner 10.
