In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0033] Figure 1 is a schematic sectional view of an air conditioner 10 according to an embodiment of the present application; Figure 2 is Figure 1 is a schematic view of a first air guide assembly 14 of the air conditioner 10 shown.

[0034] Referring to Figure 1 , the air conditioner 10 of the present embodiment includes a first air guide assembly 14 and a supply fan 12. The first air guide assembly 14 is arranged at an indoor air outlet of the air conditioner, for adjusting the longitudinal air outlet direction of the indoor air outlet, and is preset with a plurality of working positions. The supply fan 12 is arranged in the air conditioner, for forming an air flow blown out of the indoor air outlet.

[0035] In some optional embodiments, as Figure 2As shown by the dashed line in FIG. 1, 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 in the open state. Among them, 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 angle between any two adjacent working positions of the first air guide assembly 14 is equal, that is, the rotation angle of the first air guide assembly 14 required when swinging from one working position to the next working position is equal. For example, in the embodiment shown in FIG. 1, the swing angle is set to 15°, so that the first air guide assembly 14 needs to swing a total of 5 times and rotate 75° from the working position H0 to the working position H5. Figure 2

[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 according to the air outlet of the air conditioner 10. At the same time, although Figure 1 In the embodiment shown in FIG. 1, the first air guide assembly 14 of the air conditioner 10 only includes one air guide plate, but it can be understood that in other embodiments, the first air guide assembly 14 can include two or more air guide plates, which are not limited here.

[0038] Figure 3 FIG. 2 is a flowchart of a control method of the air conditioner 10 according to an embodiment of the present application.

[0039] Referring to FIG. 2, Figure 3 The control method of the air conditioner 10 generally includes:

[0040] Step S302, obtaining the blowing mode and the running mode of the air conditioner 10;

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

[0042] Step S306, if yes, controlling the first air guide assembly 14 to swing reciprocally, and stopping at each working position;

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

[0044] ​Generally, as long as the air conditioner 10 is started, the supply air fan 12 will start rotating and blowing air flow to the air outlet. In the embodiment, if the supply air mode of the air conditioner 10 is the preset reciprocating supply air mode, the air conditioner 10 will adjust the preset rotating speed of the supply air fan 12 and make the supply air fan 12 rotate at the preset rotating speed.

[0045] The air conditioner 10 can be preset with multiple supply air modes, and the reciprocating supply air mode includes the reciprocating swinging of the first air guide assembly 14 between the working positions thereof. In some alternative embodiments, a second air guide assembly 16 is further arranged at the indoor air outlet, and the second air guide assembly 16 is used to adjust the transverse air outlet direction of the indoor air outlet, and at this time, the reciprocating supply air mode also includes the reciprocating swinging of the second air guide assembly 16.

[0046] The operation modes of the air conditioner 10 include a cooling mode and a heating mode. In the cooling mode, the air conditioner 10 blows cooling air flow to the room from the air outlet to cool the room, and in the heating mode, the air conditioner 10 blows heating air flow to the room from the air outlet to increase the temperature in the room.

[0047] Based on the control method of the air conditioner 10 in the above embodiment, the first air guide assembly 14 will stop at each working position during the reciprocating swinging. In some alternative embodiments, the first air guide assembly 14 has a preset preset stopping time, and the first air guide assembly 14 will stop for the preset stopping time when reaching each working position. The preset rotating speed of the supply air fan 12 will change with the working position of the first air guide assembly 14, so that the air outlet speed and the air outlet volume of the air conditioner 10 at different air outlet heights also differ. Specifically, for the cooling mode and the heating mode of the air conditioner 10, the air outlet volume of the air conditioner 10 at different air outlet heights in each working mode is adjusted accordingly.

[0048] In the control method of the existing air conditioner, the air guide plate is arranged to swing at a uniform speed, and is generally arranged to reciprocate up and down or left and right without interruption, and at the same time, the supply air fan works at a preset fixed rotating speed, so that the air conditioner blows the air flow carrying cold or heat to the room in a uniform distribution manner in the up-down or left-right direction. The prior art believes that the air conditioner works in this way can maximize the uniform temperature adjustment in the room.

[0049] However, the present application overcomes this technical prejudice creatively, not only sets the first air guide assembly 14 to stay in each working position after each swing, but further adjusts the preset rotating speed of the air supply fan 12 when the first air guide assembly 14 is in each working position according to the operation mode of the air conditioner 10, so that the indoor air outlet of the air conditioner 10 no longer blows the air flow to the room in a uniform distribution manner, but increases or decreases the air volume at a specific air outlet height.

[0050] Generally speaking, when the air conditioner operates in the cooling mode, it usually indicates that the air temperature in the room is high, so the user needs the air conditioner to cool the room, and when the air conditioner operates in the heating mode, it is the opposite. Because the cold and hot air has different densities, when the cold and hot air meets, the cold air will sink and the hot air will float. For the air conditioner with the air guide plate swinging uniformly and continuously and the air supply fan working at a fixed rotating speed, when it operates in the cooling mode, although the air flow carrying cold air is blown out uniformly from the air outlet, from the whole room, most of the cold air will sink and accumulate near the air outlet area, which is one of the reasons why the temperature near the air outlet area is much lower than the area far from the air outlet even if the air conditioner is turned on in the up-down air sweeping mode.

[0051] When this kind of air conditioner operates in the heating mode, although the air flow carrying heat is blown out uniformly from the air outlet, from the whole room, the cold air in the room is still concentrated at a low height, and the heat is continuously accumulated upwards, so the air flow blown out by the air conditioner cannot disperse or heat the cold air at a low height well. At the same time, because the user usually sits or lies at a low height in the room, the intermittent hot air flow and the cold air flow squeezed back after the hot air flow blows will form a convection of cold and hot, and the user's experience may be worse than not turning on the heating mode before the air is completely heated.

[0052] On the basis of realizing that the prior art can theoretically uniformly adjust the temperature of the room, but the actual uniform temperature adjustment effect is not ideal, the embodiment creatively no longer controls the first air guide assembly 14 in the traditional uniform continuous reciprocating swing mode, but sets the first air guide assembly 14 to stop at each working position once for each swing, and the preset rotating speed of the air supply fan 12 is also adjusted according to the change of the working position of the first air guide assembly 14 for different environments faced by the refrigeration mode and the heating mode, so that the air outlet of the air conditioner 10 increases or decreases the air outlet amount at a specific air outlet height. Due to the above control of the first air guide assembly 14 and the air supply fan 12 for different operating modes, whether the operating mode is in the refrigeration mode or the heating mode, the air conditioner 10 can better supply air at a specific air outlet height, so that the air conditioner 10 has a better uniform temperature adjustment effect on different parts of the room with different distances from the air conditioner 10.

[0053] Figure 1 The second air guide assembly 16 is also shown in the figure. The second air guide assembly 16 can reciprocate left and right within a preset range, so as to adjust the transverse air outlet direction of the air outlet. It can be understood that, Figure 1 Although only a part of the second air guide assembly 16, that is, one swing leaf, is shown, in the Figure 1 In the embodiment shown in the figure, the second air guide assembly 16 can be provided with a plurality of Figure 1 The swing leaf shown in the figure adjusts the transverse air outlet direction of the air outlet in cooperation.

[0054] In the case of determining that the air supply mode is the reciprocating air supply mode, the air conditioner 10 adjusts the preset rotating speed of the air supply fan 12 when the first air guide assembly 14 is at each working position according to the operating mode. The first air guide assembly 14 will continuously reciprocate up and down during the reciprocating air supply, for example, in Figure 2 In the embodiment shown in the figure, 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, the first air guide assembly 14 will stop at the current working position when swinging from the previous working position to the current working position. According to different operating modes of the air conditioner 10, the preset rotating speed of the air supply fan 12 when the first air guide assembly 14 is at the same working position is usually different.

[0055] The operating mode of the air conditioner 10 includes the refrigeration mode and the heating mode, and the preset rotating speed adjustment trend of the air supply fan 12 when the first air guide assembly 14 is at different working positions is also different, specifically:

[0056] In the case of the operating mode being the refrigeration mode, the preset rotating 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 rotating speed of the air supply fan 12;

[0057] In the case of the operation mode being the heating mode, the preset rotating speed of the air supply fan 12 is set to be faster when the corresponding air outlet height of the working position is lower.

[0058] When the air conditioner operates in the cooling mode, the temperature of the cooling airflow blown out of the air outlet of the air conditioner is usually lower than the temperature in the room. Since cold air is relatively heavy compared to hot air, the cooling capacity carried by the cooling airflow is more likely to accumulate under the room near the air outlet of the air conditioner, resulting in poor cooling effect at positions far away from the air conditioner, and the upper part of the room cannot be cooled well.

[0059] To overcome this problem, in some optional embodiments, the preset rotating speed of the air supply fan 12 is set to be faster when the corresponding air outlet height of the working position is higher. Thus, during the process of the first air guide assembly 14 completely reciprocating once, the preset rotating speed of the air supply fan 12 is faster when the corresponding air outlet height of the working position of the first air guide assembly 14 is higher. During this period, the air conditioner 10 can blow more cooling airflow to the upper part of the room and the positions far away from the air conditioner, so that the upper part of the room where hot air accumulates and the positions far away from the air conditioner where sufficient cooling capacity cannot be received can be cooled sufficiently, thereby uniformly cooling the entire room. Moreover, since the preset rotating speed of the air supply fan 12 is also slower when the corresponding air outlet height of the working position of the first air guide assembly 14 is lower, too much cooling capacity will not accumulate near the air outlet of the air conditioner 10, and an excessive temperature difference will not occur in the entire room.

[0060] When the air conditioner operates in the heating mode, the temperature of the heating airflow blown out of the air outlet of the air conditioner is usually higher than the temperature in the room. Since hot air is relatively light compared to cold air, the heat carried by the heating airflow is more likely to accumulate at the higher part of the room, resulting in users sitting or lying in the lower part being surrounded by cold air, and the convection caused by the intermittent blowing of the heating airflow also causes the users to be cold and hot alternately, resulting in a poor experience.

[0061] To overcome this problem, in some optional embodiments, the preset rotating speed of the air supply fan 12 is set to be faster when the corresponding air outlet height of the working position is lower. Thus, during the process of the first air guide assembly 14 completely reciprocating once, the preset rotating speed of the air supply fan 12 is faster when the corresponding air outlet height of the working position of the first air guide assembly 14 is lower. During this period, the air conditioner 10 can blow more 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, so that the overall temperature in the room rises faster.

[0062] The control method of this embodiment not only makes the air conditioner 10 more effective at uniformly regulating the temperature in the room, but also reduces the preset speed of the air supply fan 12 at unnecessary air outlet heights, which is more energy-efficient than making the air supply fan 12 work at a fixed speed.

[0063] In the above embodiments, the preset speed of the blower 12 is generally adjusted using one of the following two preferred implementation methods:

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

[0065] In other words, in this embodiment, the air conditioner 10 has a preset speed that corresponds one-to-one with 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 speed.

[0066] For example, the first air guide assembly 14 has the following characteristics: Figure 2 The diagram shows a total of six operating positions, including H0 to H5, and the air supply fan 12 is preset with corresponding speeds from v0 to v5. The preset speed can be the maximum speed v of the air conditioner 10 in the current mode. max As a baseline, when the air conditioner 10 is in cooling mode, the preset speed v0 can be set to 50% of v0. max Accordingly, v1 is set to 60% v max v2 is set to 70% max v3 is set to 80% max v4 is set to 90% 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, then 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 rotational speed of the air supply fan 12 at each working position of the first air guide assembly 14 includes: adjusting the preset rotational speed of the air supply fan 12 as the first air guide assembly 14 swings toward a working position.

[0068] That is, in the present embodiment, the preset rotating speed of the air supply fan 12 is adjusted smoothly during the swinging of the first air guide assembly 14. Generally, the specific adjustment mode for adjusting the preset rotating speed of the air supply fan 12 is set as follows: the preset rotating speed of the air supply fan 12 is adjusted at a preset change rate, so as to improve the smoothness of the preset rotating speed during the adjustment, i.e. the air supply fan 12 adjusts the preset rotating 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 swinging angle between any two adjacent working positions is equal and is 15°. Thus, when the operation mode of the air conditioner 10 is the cooling mode, the preset rotating speed of the air supply fan 12 is adjusted at an acceleration rate of 1% v max for each 1.5° of the swinging of the first air guide assembly 14 during the swinging of the first air guide assembly 14 from the working position H0 to the working position H1. The preset rotating speed of the air supply fan 12 is adjusted to end at the same time when the first air guide assembly 14 swings to the working position H1.

[0070] In addition to the above embodiment of controlling the air supply fan 12, in some alternative embodiments, the uniform temperature regulating effect of the air conditioner 10 can be further improved and the energy consumption of the air conditioner 10 can be reduced by combining the control of the compressor 18 of the air conditioner 10.

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

[0072] The faster the preset rotating speed of the air supply fan 12, the more cooling or heating capacity the air conditioner 10 needs, and similarly, the slower the preset rotating speed of the air supply fan 12, the less cooling or heating capacity the air conditioner 10 needs. The synchronous adjustment of the operation frequency of the compressor 18 and the preset rotating speed of the air supply fan 12 enables both to work more reasonably, further reducing the energy consumption of the air conditioner 10.

[0073] In some alternative embodiments, the air conditioner 10 further comprises a second air guide assembly 16 arranged at the air outlet together with the first air guide assembly 14, for adjusting the horizontal air outlet direction of the indoor air outlet. At this time, the control method of the air conditioner 10 further comprises:

[0074] In each preset stay duration of the first air guide assembly 14, the second air guide assembly 16 swings back and forth once, and the time for the second air guide assembly 16 to swing back and forth once is equal to the preset stay duration.

[0075] The first air guide assembly 14 swings back and forth between the working positions, which is to say, it swings from one working position to the next working position, and then stays at the working position for a certain duration, during which the air conditioner 10 keeps blowing air at the air outlet height. After the preset stay duration ends, the first air guide assembly 14 swings to the next working position and repeats the step (during the swinging of the first air guide assembly 14, the air conditioner 10 keeps blowing air). In this 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 stay duration corresponding to the working position where the first air guide assembly 14 currently swings to, the second air guide assembly 16 ends the swinging at the same time when the first air guide assembly 14 starts to swing to the next working position.

[0076] Since the preset stay durations of the first air guide assembly 14 at different working positions are different, the time for the second air guide assembly 16 to swing back and forth once is also different, but no matter how long or short the preset stay duration is, the second air guide assembly 16 preferably swings at a constant speed during the swinging back and forth, that is, during the same swinging back and forth, the second air guide assembly 16 swings at the same angle within the same duration. In particular, in some optional embodiments, the second air guide assembly 16 is driven by a motor capable of bidirectional rotation, and when the second air guide assembly 16 swings to the leftmost end or the rightmost end, the motor needs to stop rotating and switch the rotation direction. The second air guide assembly 16 swings at a constant speed during the swinging back and forth refers to that, excluding the special case, the second air guide assembly 16 swings from one end to the other end at a constant speed.

[0077] The second air guide assembly 16 is usually preset with an initial position, and the second air guide assembly 16 swings from the initial position each time and returns to the initial position after swinging back and forth once. In some optional embodiments, the initial position of the second air guide assembly 16 is a position where the second air guide assembly 16 is perpendicular to the air outlet, or a position where the air flow is blown directly to the front of the air outlet of the air conditioner 10, which is usually located at the middle position of the swinging range of the second air guide assembly 16. The second air guide assembly 16 swings back and forth once refers to that the second air guide assembly 16 swings from the initial position to one end of the swinging range, then swings to the other end, and finally swings back to the initial position.

[0078] In the further embodiment provided with the second air guiding assembly 16, the second air guiding assembly 16 reciprocates once during the first air guiding assembly 14 staying at the working position, and makes the air conditioner 10 sweep air left and right for one round, effectively increasing the horizontal air supply area of the air conditioner 10, and further improving the uniform temperature adjusting effect of the air conditioner 10 on the room. Since the second air guiding assembly 16 reciprocates once when the first air guiding assembly 14 is at each working position, the air conditioner 10 can sweep air left and right once at each air outlet height, and there is no case that the air conditioner 10 does not sweep air left and right or does not sweep air to one side at a certain air outlet height, avoiding the occurrence of air sweeping dead angle in the room.
