[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.

[0003] In the existing control method of the air conditioner, the air guide plate is set to swing at a uniform speed, and is generally set to swing up and down or left and right continuously. At the same time, the air supply fan is also working at a preset fixed speed, so that the air conditioner blows the outlet air flow carrying cold or heat into the room in an evenly distributed manner in the up and down or left and right directions. The prior art believes that the air conditioner working in this way can adjust the temperature in the room to the greatest extent. Summary of the invention

[0012] When the operation mode is the heating mode, the preset speed of the air supply fan is set as follows: the lower the air outlet height corresponding to the working position, the faster the preset speed of the air supply fan.

[0013] Optionally, the air conditioner further comprises a compressor. When the air supply mode is a preset reciprocating air supply mode, the control method of the air conditioner further comprises: adjusting the operating frequency of the compressor according to a preset rotation speed of the air supply fan.

[0014] Optionally, the control method of the air conditioner further includes: setting the operating frequency to increase as the preset speed of the air supply fan increases.

[0017] The control method of the air conditioner also includes: controlling the second air guide component to swing back and forth once within each preset stay 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 stay time.

[0018] Optionally, the step of controlling the second air guide assembly to swing back and forth once is configured as follows: controlling the second air guide assembly to swing at a uniform speed during the reciprocating swing.

[0029] 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.

[0031] Secondly, it should be noted that in the description of the present application, terms such as "inside", "outside", "up", "down", "front", and "back" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0032] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example disclosed in the present application. 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.

[0033] 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 14 of the air conditioner 10 is shown.

[0034] refer to Figure 1 As shown, the air conditioner 10 of this embodiment includes a first air guide assembly 14 and an air supply fan 12. The first air guide assembly 14 is arranged at the indoor air outlet of the air conditioner, and is used to adjust the longitudinal air outlet direction of the indoor air outlet, and is preset with multiple working positions. The air supply fan 12 is arranged in the air conditioner, and is used to form an air flow blowing out of the indoor air outlet.

[0035] In some optional embodiments, such as Figure 2As shown by the dotted lines in , the first air guide assembly 14 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 14 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 14 swings to the working position H5, the longitudinal air outlet direction tends to be upward, and the air outlet height is the highest.

[0036] In some optional embodiments, the swing angles between any two adjacent working positions of the first air guide assembly 14 are equal, that is, the rotation angles that the first air guide assembly 14 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 14 needs to swing 5 times and rotate 75° from the working position H0 to H5.

[0037] It should be noted that the number of working positions of the first air guide assembly 14 and the swing angle between any two adjacent working positions of the first air guide assembly 14 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 14 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 14 may also include two or more air guide plates, which is not limited here.

[0038] Figure 3 1 is a flow chart of a control method of an air conditioner 10 according to an embodiment of the present invention.

[0039] refer to Figure 3 As shown, the control method of the air conditioner 10 generally includes:

[0040] Step S302, obtaining the air supply mode and operation mode of the air conditioner 10;

[0041] Step S304, determining whether the air supply mode is a preset reciprocating air supply mode;

[0042] Step S306: If yes, control the first air guide assembly 14 to swing back and forth and stop when reaching each working position;

[0043] Step S308, adjusting the preset rotation speed of the air supply fan 12 at each working position of the first air guide assembly 14 according to the operation mode.

[0044] Generally speaking, once the air conditioner 10 is started, its air supply fan 12 will start to rotate and blow air out to the air outlet. In this embodiment, if the air supply mode of the air conditioner 10 is a preset reciprocating air supply mode, the air conditioner 10 will adjust the preset speed of the air supply fan 12 and make the air supply fan 12 rotate at the preset speed.

[0045] 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 14 reciprocates between its working positions. In some optional embodiments, a second air guide assembly 16 is further provided at the indoor air outlet, and the second air guide assembly 16 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 16.

[0046] 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.

[0047] Based on the control method of the air conditioner 10 of the above embodiment, the first air guide component 14 will stop when it reaches each working position during the reciprocating swing. In some optional embodiments, the first air guide component 14 has a preset dwell time, and the first air guide component 14 will continue to stay for the preset dwell time when it reaches each working position. The preset speed of the air supply fan 12 will vary with the different working positions of the first air guide component 14, so that the air outlet speed and air volume of the air conditioner 10 at different air outlet heights will also differ. Specifically, for the two working modes of the air conditioner 10, the cooling mode and the heating mode, the air outlet volume of the air conditioner 10 at different air outlet heights in each working mode is adjusted in a targeted manner.

[0048] In the existing control method of the air conditioner, the air guide plate is set to swing at a uniform speed, and is generally set to swing up and down or left and right continuously. At the same time, the air supply fan is also working at a preset fixed speed, so that the air conditioner blows the outlet air flow carrying cold or heat into the room in an evenly distributed manner in the up and down or left and right directions. The prior art believes that the air conditioner working in this way can adjust the temperature in the room to the greatest extent.

[0049] However, the present invention creatively overcomes this technical prejudice. Not only is the first air guide component 14 set to stay at a working position every time it swings to this position, but the preset speed of the air supply fan 12 at each working position of the first air guide component 14 is further adjusted 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 outlet air flow into the room in a uniformly distributed manner, but instead increases or decreases the air volume at a specific air outlet height in a targeted manner.

[0050] 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. For air conditioners with air guide plates that continuously swing back and forth at a uniform speed and air supply fans that operate at a fixed speed, when it is running in cooling mode, although the air flow 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.

[0051] 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.

[0052] 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 14 in a traditional uniform continuous reciprocating swinging manner, but sets the first air guide assembly 14 to stay at a working position once each time it swings to a working position, and the preset speed of the air supply fan 12 is also adjusted accordingly with the change of the working position of the first air guide assembly 14 in response to the different environments faced by the cooling mode and the heating mode, so that the indoor air outlet of the air conditioner 10 increases or decreases the air volume at a specific air outlet height in a targeted manner. Since this embodiment makes the above-mentioned control of the first air guide assembly 14 and the air supply fan 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 better supply air to the specific air outlet height in a targeted manner, so that the air conditioner 10 has a better even temperature adjustment effect in various places of the room at different distances from the air conditioner 10.

[0053] Figure 1 The second air guide assembly 16 is also shown. The second air guide assembly 16 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 16, i.e., one of the swing blades, is shown, Figure 1 In the embodiment shown, the second air guide assembly 16 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.

[0054] When the air supply mode is determined to be the reciprocating air supply mode, the air conditioner 10 will adjust the preset speed of the air supply fan 12 at each working position of the first air guide component 14 according to the operating mode. During the reciprocating air supply, the first air guide component 14 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 14 swings from the previous working position to the current working position, it will stay at the current working position. According to different operating modes of the air conditioner 10, the preset speed of the air supply fan 12 when the first air guide component 14 is in the same working position is usually different.

[0055] The operation modes of the air conditioner 10 include a cooling mode and a heating mode. The preset speed adjustment trends of the air supply fan 12 are different when the first air guide assembly 14 is in different working positions. Specifically:

[0056] When the operation mode is the cooling mode, the preset speed of the air supply fan 12 is set to: the higher the air outlet height corresponding to the working position, the faster the preset speed of the air supply fan 12;

[0057] When the operation mode is the heating mode, the preset rotation speed of the air supply fan 12 is set as follows: the lower the air outlet height corresponding to the working position, the faster the preset rotation speed of the air supply fan 12.

[0058] 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.

[0059] In order to overcome this problem, in some optional embodiments, the preset speed of the air supply fan 12 is set to: the higher the outlet height corresponding to the working position, the faster the preset speed of the air supply fan 12. Therefore, in the process of the first air guide component 14 completely swinging back and forth once, the higher the outlet height corresponding to the working position of the first air guide component 14, the faster the preset speed of the air supply fan 12. During this period, the air conditioner 10 can blow more cooling air 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 speed of the air supply fan 12 is relatively slow when the outlet height corresponding to the working position of the first air guide component 14 is relatively low, it will not cause too much 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.

[0060] 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.

[0061] In order to overcome this problem, in some optional embodiments, the preset speed of the air supply fan 12 is set to: the lower the air outlet height corresponding to the working position, the faster the preset speed of the air supply fan 12. Therefore, during the process of the first air guide component 14 completely swinging back and forth once, the lower the air outlet height corresponding to the working position of the first air guide component 14, the faster the preset speed of the air supply fan 12. 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.

[0062] The control method of this embodiment not only enables the air conditioner 10 to achieve a better uniform temperature control effect in the room, but also reduces the preset speed of the air supply fan 12 at unnecessary air outlet heights, thereby saving more energy and electricity than operating the air supply fan 12 at a fixed speed.

[0063] In the above embodiments, the preset speed of the air supply fan 12 is generally adjusted in one of the following two preferred implementations:

[0064] In one embodiment, the step of adjusting the preset speed of the air supply fan 12 at each working position of the first air guide component 14 includes: obtaining the preset speed of the air supply fan 12 corresponding to each working position; when the first air guide component 14 swings to each working position, controlling the air supply fan 12 to adjust to the corresponding preset speed.

[0065] That is to say, in this embodiment, the air conditioner 10 is preset with a preset rotation speed corresponding to the working position of the first air guide component 14, so that when the first air guide component 14 swings to a working position, the air supply fan 12 is controlled to adjust to continue working at the corresponding preset rotation speed.

[0066] For example, the first air guide component 14 has Figure 2 There are a total of 6 working positions including H0 to H5, and the air supply fan 12 is preset with corresponding preset speeds v0 to v5. The preset speed can be the maximum speed v of the air conditioner 10 in the current mode. max As a reference value, when the operation mode of the air conditioner 10 is the cooling mode, the preset speed v0 can be set to 50% v max , accordingly, v1 is set to 60%v max , v2 is set to 70% v max , v3 is set to 80% v max , v4 is set to 90% v max , v5 is set to 100% v max In this embodiment, if the first air guide assembly 14 swings from the working position H0 to the working position H1, the preset speed of the air supply fan 12 is controlled accordingly from 50% v max Increase to 60%v max .

[0067] In another embodiment, the step of adjusting the preset speed of the air supply fan 12 at each working position of the first air guide component 14 includes: adjusting the preset speed of the air supply fan 12 during the swinging of the first air guide component 14 to a working position.

[0068] That is, in this embodiment, the preset speed of the air supply fan 12 is adjusted smoothly during the swinging process of the first air guide assembly 14. Usually, the specific adjustment method of adjusting the preset speed of the air supply fan 12 is set to: adjust the preset speed of the air supply fan 12 at a preset change rate, thereby improving the stability of the preset speed during the adjustment process, even if the air supply fan 12 adjusts the preset speed at a constant acceleration.

[0069] For example, the first air guide assembly 14 has a total of 6 working positions including H0 to H5, and the swing angle between any two adjacent working positions is equal, and the swing angle is 15°. Therefore, when the operation mode of the air conditioner 10 is the cooling mode, when the first air guide assembly 14 swings from the working position H0 to the working position H1, the first air guide assembly 14 will swing 1.5°, and the swing angle will increase by 1%v. max The acceleration rate adjusts the preset speed of the air supply fan 12. When the first air guide assembly 14 swings to the working position H1, the preset speed of the air supply fan 12 is also adjusted.

[0070] In addition to the above-mentioned embodiment of controlling the air supply fan 12, in some optional implementations, the compressor 18 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.

[0071] Specifically, the operating frequency of the compressor 18 is adjusted according to the preset speed of the air supply fan 12, and the operating frequency of the compressor 18 increases as the preset speed of the air supply fan 12 increases. In other words, when the first air guide assembly 14 swings from one working position to the next working position, if the preset speed of the air supply fan 12 increases, the operating frequency of the compressor 18 is increased accordingly. Similarly, if the preset speed of the air supply fan 12 decreases, the operating frequency of the compressor 18 is decreased accordingly.

[0072] The faster the preset speed of the air supply fan 12 is, the more cooling or heating the air conditioner 10 needs. Similarly, the slower the preset speed of the air supply fan 12 is, the less cooling or heating the air conditioner 10 needs. Synchronizing the operating frequency of the compressor 18 with the preset speed of the air supply fan 12 can make both work more reasonably, further reducing the energy consumption of the air conditioner 10.

[0073] In some optional embodiments, the air conditioner 10 further includes a second air guide assembly 16 disposed at the air outlet in the same manner as the first air guide assembly 14, for adjusting the lateral air outlet direction of the indoor air outlet. In this case, the control method of the air conditioner 10 further includes:

[0074] During each preset stay time of the first air guide component 14, the second air guide component 16 is controlled to swing back and forth once; and the time for the second air guide component 16 to swing back and forth once is equal to the preset stay time.

[0075] The first air guide assembly 14 swings back and forth between the working positions. In simple terms, it swings from one working position to the next working position first, and then stays at this working position for a certain period of 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 assembly 14 swings to the next working position and repeats this step (during the swinging of the first air guide assembly 14, the air conditioner 10 continues to discharge air). In the present embodiment, when the first air guide assembly 14 swings to a working position and stays, the second air guide assembly 16 starts to swing and swings back and forth once. In particular, the first air guide assembly 14 and the second air guide assembly 16 do not swing at the same time, that is, when the first air guide assembly 14 swings to a working position, the second air guide assembly 16 starts to swing. Since the time for the second air guide assembly 16 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 assembly 14, when the second air guide assembly 16 ends swinging, the first air guide assembly 14 also starts to swing to the next working position.

[0076] Since the preset dwell time of the first air guide component 14 in different working positions is different, the time for the second air guide component 16 to swing back and forth once is also different. However, regardless of the preset dwell time, the second air guide component 16 preferably swings at a uniform speed during the reciprocating swinging process, that is, during the same reciprocating swinging process, the second air guide component 16 swings at the same angle within the same time length. In particular, in some optional embodiments, the second air guide component 16 is driven by a motor capable of bidirectional rotation, and when the second air guide component 16 swings to its leftmost or rightmost end, the motor needs to stop and switch the rotation direction. The second air guide component 16 swings at a uniform speed during the reciprocating swinging process means that after excluding this special case, the second air guide component 16 preferably swings at a uniform speed during the swinging process from one end to the other end.

[0077] The second air guide component 16 is usually preset with an initial position, and the second air guide component 16 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 16 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 16. The second air guide component 16 swings back and forth once means that the second air guide component 16 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.

[0078] In the above further embodiment in which the second air guide assembly 16 is provided, the second air guide assembly 16 swings back and forth once while the first air guide assembly 14 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.
