[0002] In household air conditioners, the automatic swing function of the air guide plate at the air outlet is a very common setting. In summer, if users want to increase the air supply coverage area of ​​the air conditioner so that multiple users distributed throughout the room can enjoy the comfortable cool air blown by the air conditioner, or if they want to evenly cool down the room, they will choose to turn on the automatic swing function of the air guide plate of the air conditioner.

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0036] Figure 1 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 is shown.

[0037] refer to Figure 1As shown, the indoor air outlet of the air conditioner 10 of this embodiment is provided with a first air guide component 12, which is used to adjust the longitudinal air outlet direction of the indoor air outlet and has multiple preset working positions. Figure 2 As shown by the dotted lines in , 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 opened. 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 angles between any two adjacent working positions of the first air guide assembly 12 are equal, that is, the rotation angles that the first air guide assembly 12 needs to rotate through each time when it swings from one working position to the next working position are equal. Figure 2 In the illustrated embodiment, 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 and the swing angle between any two adjacent working positions of the first air guide assembly 12 can be adjusted accordingly according to the air outlet of the air conditioner 10. Figure 1 In the illustrated embodiment, the first air guide assembly 12 of the air conditioner 10 includes only one air guide plate as shown in the figure, but it can be 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 1 is a flow chart of a control method of 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, obtaining the air supply mode and operation mode of the air conditioner 10;

[0043] Step S304, determining whether the air supply mode is a preset reciprocating air supply mode;

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

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

[0046] The air conditioner 10 may be preset with a plurality of air supply modes, wherein the reciprocating air supply mode includes an air supply mode in which the first air guide assembly 12 reciprocates between its working positions. In some optional embodiments, a second air guide assembly 14 is further provided at the indoor air outlet, and the second air guide assembly 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 swing of the second air guide assembly 14.

[0047] The operating modes of the air conditioner 10 include a cooling mode and a heating mode. In the cooling mode, the air conditioner 10 will blow cooling air into the room from the air outlet to cool the room. In the heating mode, the air conditioner 10 will blow heating air into the room from the air outlet to increase the temperature in the room.

[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 stay time during the reciprocating swing process, that is, the preset stay time of the first air guide component 12 is different according to the different air outlet heights, so that the air conditioner 10 can fully supply air to the room at a specific air outlet height. Specifically, for the two working modes of the air conditioner 10, the swing mode of the first air guide component 12 in each working mode is adjusted in a targeted manner.

[0049] In the existing control methods of air conditioners, the air guide plates are all set to swing at a uniform speed, and are generally set to swing up and down or left and right continuously, so that the air conditioner blows the outlet airflow carrying cold or heat into the room in a uniformly distributed manner in the up and down directions or left and right directions. The prior art believes that this uniform and continuous reciprocating swing of the air guide plate is the most preferred swinging mode, which can adjust the temperature in the room to the greatest extent.

[0050] However, the present invention creatively overcomes this technical prejudice, and sets the first air guide component 12 to stay at a working position for a corresponding preset stay time each time it swings to a working position. The preset stay time of the first air guide component 12 at a specific working position is thereby specifically extended or shortened according to the operating mode of the air conditioner 10, so that the indoor air outlet of the air conditioner 10 no longer blows the outlet air flow into the room in a uniformly distributed manner, but instead specifically increases or decreases the outlet air flow rate at a specific outlet height.

[0051] Generally speaking, when the air conditioner is running in cooling mode, it often means that the air temperature in the room is high, so the user needs the air conditioner to cool down the room, and the opposite is true when the air conditioner is running in heating mode. Due to the different densities of cold and hot air, when cold and hot air meet, the cold air will sink and the hot air will float up. For air conditioners with air guide plates that continuously swing back and forth at a uniform speed, when they are running in cooling mode, although the outlet airflow carrying cold air is blown out evenly from the air outlet, from the perspective of the whole room, most of the cold air will sink and accumulate in the area near the air outlet. This is one of the reasons why even if the existing air conditioner is turned on the up and down sweeping mode, the temperature of the area near the air outlet is much lower than that of the area far away from the air outlet.

[0052] When this air conditioner is running in heating mode, although the outlet airflow carrying heat is blown out evenly from the air outlet, the cold air in the room is still concentrated at a lower height, and the heat continues to accumulate upwards. The airflow blown out by the air conditioner cannot effectively disperse or heat the cold air at a lower height. At the same time, since users often sit or lie at a lower height in the room, the intermittent hot air flow and the cold air flow squeezed back after the hot air flow blows through will form a cold and hot convection. Before the air is fully heated, the user experience may be worse than not turning on the heating mode.

[0053] Recognizing that the prior art can theoretically evenly adjust the temperature of a room, but the actual even temperature adjustment effect is not ideal, this embodiment creatively no longer controls the first air guide assembly 12 in a traditional uniform continuous reciprocating swinging manner, but sets the first air guide assembly 12 to stay at a corresponding preset stay time each time it swings to a working position, and specifically extends or shortens the preset stay time of the first air guide assembly 12 at a specific working position in response to different environments faced by the cooling mode and the heating mode, so that the indoor air outlet of the air conditioner 10 specifically increases or decreases the air flow rate at a specific air outlet height. Since this embodiment makes the above-mentioned control of the first air guide assembly 12 for different operating modes, regardless of whether the operating mode is in the cooling mode or the heating mode, the air conditioner 10 can specifically deliver air to a specific air outlet height, so that the air conditioner 10 has a better even temperature adjustment effect in various rooms at different distances from the air conditioner 10.

[0054] Figure 1 The second air guide assembly 14 is also shown. The second air guide assembly 14 can swing back and forth within a preset range to adjust the lateral air outlet 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 the swing blades, is shown. Figure 1In the embodiment shown, the second air guide assembly 14 may be provided with a plurality of Figure 1 The swing blades shown are shown, and the lateral air outlet direction of the air outlet is adjusted accordingly.

[0055] When the air supply mode is determined to be the reciprocating air supply mode, the air conditioner 10 will determine the preset stay time of the first air guide component 12 at each working position according to the operation mode. During the reciprocating air supply, the first air guide component 12 will continuously swing up and down, for example, Figure 2 In the embodiment shown, it will gradually swing from the working position H0 to H5, and then gradually swing from the working position H5 to H0, and so on. Among them, when the first air guide component 12 swings from the previous working position to the current working position, it will stay at the current working position for a corresponding preset stay time. According to different operating modes of the air conditioner 10, the preset stay time of the first air guide component 12 at the same working position is usually different, and at the same time, the preset stay time of the first air guide component 12 at different working positions under the same operating mode is usually different.

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

[0057] Step S402, obtaining the air supply mode and operation mode of the air conditioner 10;

[0058] Step S404, determining whether the air supply mode is a preset reciprocating air supply mode;

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

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

[0061] Step S410, within each preset stay 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 stay time.

[0062] The first air guide component 12 will swing back and forth between the working positions. In simple terms, it will first swing from one working position to the next working position, and then stay at this working position for a corresponding preset dwelling time. During this period, the air conditioner 10 will maintain this air outlet height to discharge air. After the preset dwelling time is over, the first air guide component 12 will swing to the next working position and repeat this step (during the swinging of the first air guide component 12, the air conditioner 10 can continue to discharge air). In the above embodiment, when the first air guide component 12 swings to a working position and stays, the second air guide component 14 will start to swing and swing back and forth once. In particular, the first air guide component 12 and the second air guide component 14 do not swing at the same time, that is, when the first air guide component 12 swings to a working position, the second air guide component 14 starts to swing. Since the time for the second air guide component 14 to swing back and forth once is equal to the preset dwelling time corresponding to the working position currently swung to by the first air guide component 12, when the second air guide component 14 ends its swinging, the first air guide component 12 also starts to swing to the next working position.

[0063] Since the preset dwell time of the first air guide component 12 in different working positions is different, the time for the second air guide component 14 to swing back and forth once is also different. However, regardless of the preset dwell time, the second air guide component 14 preferably swings at a uniform speed during the reciprocating swinging process, that is, during the same reciprocating swinging process, the second air guide component 14 swings at the same angle within the same time length. In particular, in some optional embodiments, the second air guide component 14 is driven by a motor capable of bidirectional rotation, and when the second air guide component 14 swings to its leftmost or rightmost end, the motor needs to stop and switch the rotation direction. The second air guide component 14 swings at a uniform speed during the reciprocating swinging process, which means that after excluding this special case, the second air guide component 14 preferably swings at a uniform speed during the swinging process from one end to the other end.

[0064] The second air guide component 14 is usually preset with an initial position, and the second air guide component 14 will swing from the initial position each time and return to the initial position after swinging back and forth once. In some optional embodiments, the initial position of the second air guide component 14 is a position perpendicular to the air outlet, or a position where the outlet air flows to blow directly in front of the air outlet of the air conditioner 10, and this initial position is usually located in the middle of the left and right swing range of the second air guide component 14. The second air guide component 14 swings back and forth once means that the second air guide component 14 swings from the initial position to one end of the swing range, then to the other end, and finally swings back to the initial position.

[0065] In the above further embodiment in which the second air guide assembly 14 is provided, the second air guide assembly 14 swings back and forth once while the first air guide assembly 12 stays in the working position, and makes the air conditioner 10 sweep air left and right once, effectively increasing the lateral air supply area of ​​the air conditioner 10, and further improving the uniform temperature adjustment effect of the air conditioner 10 on various parts of the room. Since the second air guide assembly 14 swings 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, and there is no situation where the air conditioner 10 does not sweep air left and right or does not sweep air to a certain side at a certain air outlet height, thereby avoiding the occurrence of air sweeping dead corners in the room.

[0066] The operation mode of the air conditioner 10 includes a cooling mode and a heating mode. According to different operation modes of the air conditioner 10, the preset stay time of the first air guide component 12 in the working position is also different. Specifically:

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

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

[0069] When the air conditioner is running in cooling mode, the temperature of the cooling air flow blown out from the air outlet of the air conditioner is often lower than the temperature in the room. Since cold air is heavier than hot air, the cold air carried by the cooling air flow will accumulate more in the lower part of the room near the air outlet area of ​​the air conditioner, resulting in poor cooling effect in locations far away from the air conditioner. At the same time, higher locations in the room cannot be cooled well either.

[0070] In order to overcome this problem, in some optional embodiments, the preset stay time is set to: the higher the air outlet height corresponding to the working position, the longer the corresponding preset stay time. Therefore, during the process of the first air guide component 12 completely swinging back and forth once, the first air guide component 12 can stay at the working position with a higher air outlet height for a longer time. During this period, the air conditioner 10 can blow more cooling airflow to the high and distant positions in the room, so that the high places in the room where hot air accumulates and the distant places in the room where it is difficult to receive sufficient cooling can be fully cooled, so that all places in the room can be evenly cooled. And because the preset stay time of the first air guide component 12 at the working position with a lower air outlet height is short, it will not cause excessive cooling to accumulate in the area near the air outlet of the air conditioner 10, and cause excessive temperature differences in various places in the room.

[0071] On the basis that the operation mode is the cooling mode, the preset stay time of the first air guide component 12 at each working position can be determined in the following manner:

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

[0073] That is to say, the preset stay time of the first air guide component 12 at the working position with the lowest air outlet height can be used as the basic value, and based on this basic value, the preset stay time of other working positions can be determined by adding a certain numerical value according to 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 stay time of each work position may be calculated in the following manner:

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

[0076] Where n represents the swing from the lowest working position H0 to the current working position H n The number of swings required, for example, H1 means that one swing is required from the working position H0 to the working position H1 (only for the one-way swing from the working position with the lowest air outlet height to the working position with the highest air outlet height), t s The preset delay time.

[0077] The preset delay time makes the preset stay time of the first air guide component 12 at the working position gradually extend as the air outlet height increases. According to the number of preset working positions of the air conditioner 10, the preset delay time can also be set and adjusted accordingly. For example, when the preset working positions are 6, the preset delay time can be set to 0.5 seconds, 1 second, 1.5 seconds or 2 seconds, so that the preset stay 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 stay time at the working position with the lowest air outlet height. In some optional embodiments, the preset stay 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. Then, when the preset working positions are 6 and the preset delay time is set to 1 second, the preset stay 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 optional implementations, the preset stay time of each working position can also be calculated in other ways, for example, n The preset stay time T n Set to n+1 times the preset stay time T0 at the working position H0 with the lowest air outlet height (T n =(n+1)T0) and so on.

[0079] In addition, the preset stay time of the first air guide component 12 at the working position with the highest air outlet height can be significantly longer than the preset stay time at the working position with the lowest air outlet height, and the preset stay time at the working position between the two can be slightly longer than the preset stay 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 larger than (n-1)T s ).

[0080] The above-mentioned calculation method for calculating the preset stay time of each working position is only a part of the embodiments of the present invention, and does not include a specific limitation on the calculation method of the preset stay time. In addition, identifying the working position of the first air guide component 12 with the lowest air outlet height as H0 and obtaining the preset stay time T0 as a basis for calculating the preset stay time of each working position as one of the optional implementation methods should also not be understood as including limitations on the present invention. For example, those skilled in the art can also identify the working position of the first air guide component 12 with the highest air outlet height as H0 and obtain the preset stay time T0, and simply make corresponding adjustments to the calculation method, and the same effect as the above-mentioned calculation formula can be obtained.

[0081] When the air conditioner is running in heating mode, the temperature of the heating air flow blown out of the air outlet is often higher than the temperature in the room. Since hot air is lighter than cold air, the heat carried by the heating air flow 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 heating air flow will also cause users to feel hot and cold, resulting in a poor experience.

[0082] In order to overcome this problem, in some optional embodiments, the preset stay time is set as follows: the lower the air outlet height corresponding to the working position, the longer the corresponding preset stay time. Therefore, during the process of the first air guide component 12 completely swinging back and forth once, the first air guide component 12 can stay at the working position with a lower air outlet height for a longer time. During this period, the air conditioner 10 can better blow the heating airflow to the lower part of the room where the user is located, which can not only dissipate the cold air around the user, but also heat the air in the lower part of the room more quickly, so that the overall temperature in the room rises faster.

[0083] On the basis that the operation mode is the heating mode, the preset stay time of the first air guide component 12 at each working position can be determined in the following manner:

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

[0085] That is to say, the preset stay time of the first air guide component 12 at the working position with the highest air outlet height can be used as the basic value, and based on this basic value, the preset stay time of other working positions can be determined by adding a certain numerical value according to the number of working positions between other working positions and the working position with the highest air outlet height.

[0086] The calculation method of the preset stay time of each working position in the heating mode is similar to that in the cooling mode, and the difference lies mainly in the different bases for calculating the preset stay time of each working position, so it will not be repeated here. At the same time, it can be understood that using the preset stay time of the first air guide component 12 at the working position with the highest air outlet height as the base for calculating the preset stay time of each working position as one of the optional implementations should also not be understood as including a limitation on the present invention.

[0087] In addition to the above-mentioned embodiments of controlling the first air guide component 12 and the second air guide component 14, in some optional embodiments, the compressor 16 of the air conditioner 10 can be controlled to further improve the uniform temperature control effect of the air conditioner 10 and reduce the energy consumption of the air conditioner 10 at the same time.

[0088] Specifically, the operating frequency of the compressor 16 is adjusted according to the preset residence time of the first air guide component 12 at the working position, and the operating frequency of the compressor 16 increases as the preset residence time of the first air guide component 12 increases. In other words, when the first air guide component 12 swings from one working position to the next working position with a longer preset residence time, the operating frequency of the compressor 16 is increased accordingly. It can be understood that when the first air guide component 12 swings from one working position to the next working position with a shorter preset residence time, the operating frequency of the compressor 16 will also be reduced accordingly, even if the operating frequency of the compressor 16 is reduced as the preset residence time of the first air guide component 12 decreases.

[0089] When the first air guide component 12 is located at a working position with a relatively longer preset residence time, it means that the indoor air outlet of the air conditioner 10 is at an air outlet height that needs to provide more cooling or heat, so the operating frequency of the compressor 16 is increased synchronously to meet the cooling or heating needs of the air conditioner 10. When the first air guide component 12 is located at a working position with a relatively shorter preset residence time, it means that the indoor air outlet of the air conditioner 10 is at an air outlet height that needs less cooling or heat, so the operating frequency of the compressor 16 can be reduced accordingly to reduce the energy consumption of the air conditioner 10.

[0091] refer to Figure 5 As shown, the air conditioner 10 generally includes a first air guide assembly 12, and Figure 6 As shown, the air conditioner 10 may further include a second air guide assembly 14 and a compressor 16. The air conditioner 10 further includes a control device 20, the control device 20 includes a processor 22 and a memory 24, wherein the memory 24 stores a control program, and when the control program is executed by the processor 22, it is used to implement the control method of the air conditioner 10 in the above embodiment.

[0092] The control method of the air conditioner 10 in the above embodiment can generally be applied to a wall-mounted air conditioner 10, and can also be applied to a window air conditioner 10, a cabinet air conditioner 10 or other air conditioners 10, without limitation herein.
