[0058] Air conditioners are widely used in daily life. With the increasing popularity of air conditioners, users pay more and more attention to the comfort of use. In the air conditioners in the related art, when cooling, there will be a situation where cold air blows directly to the user. Similarly, when heating, there is also a situation where hot air blows directly to the user. Whether it is heating or cooling, direct blowing to the user will affect the comfort. When the air conditioner is running in other characteristic modes, the air conditioner blows out no wind, which will cause the indoor air to be stagnant, affecting the comfort. The air conditioner provided in the embodiment of the present application can improve the above problems. The embodiment of the present application can provide a more comfortable air supply air conditioner. The air conditioner and air outlet control method provided in the embodiment of the present application can switch different air outlet modes according to different needs, effectively improving the discomfort of direct blowing of cold and hot air and the feeling of stuffiness when there is no air flow, thereby improving the comfort of users.

[0059] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0060] See also Figure 1 and Figure 2 The embodiment of the present application provides an air conditioner 100. The air conditioner 100 provided by the embodiment of the present application can effectively solve the problems of discomfort caused by direct blowing of cold or hot air and stuffiness when there is no air flow, thereby improving the comfort of users.

[0061] In the embodiment of the present application, the air conditioner 100 includes: a shell 110, a heat exchanger 120 and a fan 130, the shell 110 has a first air duct 112a and a first air inlet 112b and a first air outlet 112c connected to the first air duct 112a, a second air duct 113a and a second air inlet 113b connected to the second air duct 113a, a second air outlet 113c and a third air outlet 113d, the second air inlet 113b is connected to the first air duct 112a; the heat exchanger 120 and the fan 130 are arranged in the first air duct 112a.

[0062] When the air conditioner 100 is started, the wind entering the second air duct 113a is blown out from at least one of the second air outlet 113c and the third air outlet 113d, wherein the opening area of ​​the second air outlet 113c is larger than the opening area of ​​the third air outlet 113d.

[0063] In the embodiment of the present application, after the fan 130 and the heat exchanger 120 are started, the wind in the indoor environment enters the first air duct 112a through the first air inlet 112b, exchanges heat with the heat exchanger 120 in the first air duct 112a, and then blows toward the first air outlet 112c. Since the second air inlet 113b is connected to the second air duct 113a, the wind after heat exchange can enter the second air duct 113a, and can also be blown out from any one of the second air outlet 113c and the third air outlet 113d.

[0064] The second air inlet 113b is connected to the first air duct 112a. The first air duct 112a and the second air duct 113a are connected in the housing 110. When the air conditioner 100 is started, the air after heat exchange with the heat exchanger 120 enters the second air duct 113a and can be blown out from at least one of the second air outlet 113c and the third air outlet 113d. It can be considered that the first air duct 112a is a main air duct and the second air duct 113a is a secondary air duct. When the first air outlet 112c is opened, the air in the first air duct 112a is mainly blown out from the first air outlet 112c. When the first air outlet 112c is opened, if at least one of the second air outlet 113c and the third air outlet 113d is also opened, the air in the first air duct 112a partially enters the second air duct 113a and is blown out from at least one of the second air outlet 113c and the third air outlet 113d.

[0065] Regardless of whether the first air outlet 112c is opened or closed, after the air conditioner 100 is started, at least one of the second air outlet 113c and the third air outlet 113d will discharge air. Since the opening area of ​​the second air outlet 113c is larger than that of the third air outlet 113d, that is, the opening area of ​​the second air outlet 113c is larger, and the opening area of ​​the third air outlet 113d is smaller, at least any one of the second air outlet 113c and the third air outlet 113d can be selected for discharge according to different air outlet modes, and the air outlet combination can be adjusted to output strong wind and comfortable wind, which can improve the heating or cooling experience. Different air outlet combinations can be adjusted according to user needs, which can meet the needs of different users for different wind sensations, thereby improving the comfort of users when using.

[0066] Since the opening area of ​​the second air outlet 113c is relatively large, when the air is discharged from the second air outlet 113c, the air volume blown out from the second air outlet 113c is large, and the user can feel the large air volume. For the convenience of description, this mode is defined as a strong mode, and the strong mode includes a strong heating mode and a strong cooling mode. This air outlet mode can be applied to the situation where the difference between the indoor ambient temperature value and the set temperature value is large, and rapid cooling or rapid heating is required. For example: in the cooling mode, the difference between the ambient temperature value and the set temperature value is large, indicating that the ambient temperature value is high at this time, and the user feels hot. The strong cooling mode can have a large air volume that allows the user to feel the cold air blowing directly, which can enable the user to quickly cool down and improve the user's comfort. Similarly, in the heating mode, the difference between the ambient temperature value and the set temperature value is large, indicating that the ambient temperature value is low at this time, and the user feels cold. The large air volume of the strong heating mode can allow the user to feel the hot air blowing directly, which can enable the user to feel the temperature and improve the user's comfort.

[0067] In addition, since the opening area of ​​the third air outlet 113d is relatively small, when only the third air outlet 113d is blowing out air, the amount of air blown out from the third air outlet 113d is small. For the convenience of description, this air outlet mode is defined as a comfort mode, which includes a comfort heating mode and a comfort cooling mode. This air outlet mode can be applied to the condition that the indoor ambient temperature value is close to or equal to the set temperature value. In this case, the indoor ambient temperature value has almost reached the set temperature value. If it is blown out with a larger air volume, if it is blown directly onto the user, it may cause a lower experience. For example: in the cooling mode, the ambient temperature value is close to the set temperature value, which means that the current cooling capacity is sufficient to maintain the room temperature. If the cold air blows directly onto the user, the user will feel very cold. Then, the comfortable cooling mode is operated, and the air is discharged through the third air outlet 113d. The air outlet volume is small. Even if it blows directly onto the user, the user perceives a breeze, which can improve the user's comfort. Similarly, in the heating mode, the comfort heating mode can be operated, and air is discharged through the third air outlet 113d. The air output is small, and even if it blows directly onto the user, the user will feel a breeze, which can improve the user's comfort.

[0068] In some embodiments, the shell 110 includes a main body 114 and a panel 116, the panel 116 is movably connected to the main body 114 and can open or close the second air outlet 113c, the third air outlet 113d is set on the panel 116, the first air inlet 112b and the first air outlet 112c are set on the main body 114, and the first air outlet 112c is set above the panel 116.

[0069] The panel 116 is rotatably connected to the main body 114. The panel 116 can rotate relative to the main body 114. One side of the panel 116 is rotatably connected to the main body 114, and the spacing distance between the other side of the panel 116 and the main body 114 forms a second air outlet 113c. For the description of the panel 116, the side of the panel 116 away from the connection with the main body 114 is defined as a free side. When the free side contacts the main body 114, the second air outlet 113c is closed, and when the free side is spaced apart from the main body 114, the second air outlet 113c is opened.

[0070] The panel 116 can function as an air guide plate, and the second air outlet 113c can be opened or closed during the rotation relative to the main body 114. The panel 116 can be controlled to rotate relative to the main body 114 to open or close the second air outlet 113c. By utilizing the function of the panel 116 as an air guide plate, there is no need to separately set up an air guide plate for opening or closing the second air outlet 113c. This can reduce the number of components of the air conditioner 100, simplify the structure of the entire air conditioner 100, and make the air conditioner 100 more compact.

[0071] In addition, since the opening area of ​​the second air outlet 113c is much larger than the opening area of ​​the third air outlet 113d, when the second air outlet 113c is opened, the wind will be blown out from the second air outlet 113c with a smaller pressure, that is, the wind in the second air duct 113a will be mainly blown out from the second air outlet 113c, and the wind blown out from the third air outlet 113d is very little and can be considered almost non-existent. That is, it is not necessary to set a wind guide plate that can open or close the third air outlet 113d at the third air outlet 113d. If the third air outlet 113d needs to blow air, the second air outlet 113c can be closed.

[0072] The first air outlet 112c is arranged above the panel 116, that is, the first air outlet 112c is arranged above the second air outlet 113c and the third air outlet 113d. The first air outlet 112c is a main air outlet. When the first air outlet 112c is opened, the air volume of the first air outlet 112c is larger than the air volume of the second air outlet 113c and the air volume of the third air outlet 113d. The first air outlet 112c is arranged above the panel 116, so that the wind blown out from the first air outlet 112c can blow to a farther distance, which can increase the air outlet distance of the air conditioner 100, so that people farther away from the air conditioner 100 can blow the heat-exchanged air, thereby improving the comfort of users.

[0073] The second air inlet 113b is disposed above the second air outlet 113c and the third air outlet 113d. The air after heat exchange in the heat exchanger 120 enters the second air duct 113a from above the second air duct 113a and can flow from top to bottom.

[0074] Among them, when the panel 116 opens the second air outlet 113c, the panel 116 is in a vertical state, so that the wind blown out of the second air outlet 113c can be directed vertically downward. In the strong mode, whether it is a strong cooling mode or a strong heating mode, the vertical downward air outlet 113c can make the user feel a larger air volume, thereby improving the user's comfort.

[0075] In some embodiments, the housing 110 further includes a partition 118 , which is disposed in the main body 114 , a gap between the partition 118 and the panel 116 forms a second air duct 113 a , and the partition 118 and the main body 114 form a first air duct 112 a .

[0076] The partition 118 is located inside the main body 114, dividing the internal cavity of the main body 114 into two parts. The gap between the partition 118 and the panel 116 is the second air duct 113a, wherein the cross-section of the partition 118 can be arc-shaped, straight-line-shaped, or folded-line-shaped, and the shape of the partition 118 is not specifically limited.

[0077] That is, the first air duct 112a and the second air duct 113a are separated by the partition plate 118, and at one end of the partition plate 118, the second air inlet 113b is connected to the first air duct 112a.

[0078] In some embodiments, when the panel 116 closes the second air outlet 113c, the panel 116 is tilted. When the second air outlet 113c is closed, the wind entering the second air duct 113a is blown out from the third air outlet 113d, which is arranged on the panel 116, that is, the air outlet direction of the third air outlet 113d is tilted.

[0079] In some embodiments, there are multiple third air outlets 113 d , and the multiple third air outlets 113 d are all disposed on the panel 116 .

[0080] The opening size of the third air outlet 113d is very small, and the third air outlet 113d can be considered as a micropore. When the second air outlet 113c is closed, the wind in the second air duct 113a is separated into multiple strands by multiple third air outlets 113d when it is blown out through the third air outlet 113d. Under the obstruction of the panel 116, the wind speed of the wind blown out from the third air outlet 113d will also be greatly reduced. The wind blown out from the third air outlet 113d can be considered as a breeze, forming a comfortable and soft wind, which can avoid cold wind or hot wind blowing directly onto the user as much as possible, thereby improving the user's comfort.

[0081] The third air outlet 113d may be in a horizontal strip shape or in a circular shape.

[0082] In some embodiments, there are multiple first air inlets 112 b , and at least one first air inlet 112 b is disposed on the top and the bottom of the main body 114 .

[0083] The top of the main body 114 may be provided with a larger first air inlet 112b, or multiple first air inlets 112b with smaller openings. Similarly, the bottom of the main body 114 may be provided with a larger first air inlet 112b, or multiple first air inlets 112b with smaller openings.

[0084] A first air inlet 112b is provided at the top and bottom of the main body 114 so that wind from all directions in the indoor environment can enter the first air duct 112a, thereby improving the uniformity of cooling or heating of the air conditioner 100.

[0085] In some embodiments, the first air outlet 112c is disposed above the second air outlet 113c and the third air outlet 113d, and the third air outlet 113d is disposed above the second air outlet 113c.

[0086] Among them, the first air outlet 112c is the main air outlet, and the second air inlet 113b is arranged close to the first air outlet 112c. The wind speed and air volume of the first air outlet 112c are relatively large. The first air outlet 112c is set at the top. When the air conditioner 100 runs in strong mode, the first air outlet 112c can blow the wind after heat exchange by the heat exchanger 120 to a farther position in the room, so that the indoor air can flow quickly and can be evenly cooled or heated.

[0087] In addition, the second air outlet 113c is opened when the air conditioner 100 runs in strong mode. The second air outlet 113c is set at the bottom, which can enable the wind in the second air duct 113a to quickly enter the indoor environment, allowing the user to feel the hot air or the cold air, thereby improving the user experience and comfort.

[0088] In some embodiments, the air conditioner 100 also includes a first air guide plate 152 and a second air guide plate 154. The first air guide plate 152 is rotatably connected to the shell 110 above the first air outlet 112c, and the second air guide plate 154 is rotatably connected to the shell 110 below the first air outlet 112c. The first air guide plate 152 and the second air guide plate 154 can open or close the first air outlet 112c at the same time.

[0089] A first air guide plate 152 and a second air guide plate 154 are simultaneously provided at the first air outlet 112c. The air outlet direction of the first air outlet 112c can be adjusted by the combination of the first air guide plate 152 and the second air guide plate 154, so that the first air outlet 112c can achieve different air outlet directions in different operating modes of the air conditioner 100, thereby improving user comfort.

[0090] In some embodiments, if the difference between the indoor ambient temperature value and the set temperature value is large, it means that the current ambient temperature value is far from the set temperature value. At this time, the user's comfort is reflected in the need for rapid cooling or heating so that the indoor ambient temperature value can quickly reach the set temperature value. The issue of direct blowing is not considered, and rapid cooling or rapid heating is mainly used, that is, the air conditioner 100 runs in strong mode.

[0091] If the difference between the indoor ambient temperature and the set temperature is small, it means that the current ambient temperature is close to the set temperature, and the user's body temperature perception is relatively comfortable. At this time, the user's comfort is reflected in the need to prevent direct blowing. Therefore, the problem of preventing direct blowing needs to be considered here, that is, the air conditioner 100 operates in comfort mode.

[0092] In some embodiments, the second air guide plate 154 is disposed at the second air inlet 113b, and can guide the wind in the first air duct 112a to the second air duct 113a.

[0093] The fan 130 is not provided in the second air duct 113a, and the wind speed of the wind entering the second air duct 113a from the first air duct 112a comes from the fan 130 provided in the first air duct 112a. After the second air guide plate 154 opens the first air outlet 112c, most of the wind will be blown out from the first air outlet 112c. In order to allow some wind to enter the second air duct 113a, the second air guide plate 154 can be provided at the second air inlet 113b, which can play a certain guiding role, and guide the wind in the first air duct 112a to the second air duct 113a.

[0094] See also Figure 3 In some embodiments, when the air conditioner 100 operates in a strong cooling mode, the fan 130 operates at a first speed, the first air guide plate 152 and the second air guide plate 154 open the first air outlet 112c, the panel 116 opens the second air outlet 113c, and the air in the second air duct 113a is blown out from the second air outlet 113c;

[0095] The first air guide plate 152 is located at a maximum angle, and the second air guide plate 154 is located at a maximum angle.

[0096] When the difference between the indoor ambient temperature and the set temperature is large, it means that the current ambient temperature is high, and it is necessary to turn on the strong cooling mode to quickly cool down. In the strong cooling mode, the indoor environment needs to be cooled quickly, and the user needs to quickly perceive the cooling capacity. Here, the first air guide plate 152 and the second air guide plate 154 are opened to the maximum position, so that the opening area of ​​the first air outlet 112c is the largest, and the fan 130 runs at the first speed. The wind cooled by the heat exchanger 120 can be quickly blown out from the first air outlet 112c, so that the indoor ambient temperature can be quickly reduced, improving the user's comfort.

[0097] Among them, the first rotation speed is a relatively large rotation speed. In the stage where rapid cooling is required, the air can flow from the first air outlet 112c at a relatively large wind speed, providing more cooling capacity to the indoor environment, so that the indoor environment can be cooled down quickly and the user's comfort is improved.

[0098] In the strong cooling mode, the panel 116 is arranged vertically, so that the wind blown out of the second air outlet 113c can be directed vertically downward. In the strong cooling mode, the vertical downward air discharge from the second air outlet 113c can enable the user to perceive a larger air volume, thereby improving the user's comfort.

[0099] See also Figure 4In some embodiments, when the air conditioner 100 operates in the comfort cooling mode, the fan 130 operates at the second speed, the first air guide plate 152 and the second air guide plate 154 open the first air outlet 112c, the panel 116 closes the second air outlet 113c, and the air in the second air duct 113a is blown out from the third air outlet 113d;

[0100] The first air guide plate 152 is arranged horizontally or tilted upward, and the second air guide plate 154 is located at a maximum angle.

[0101] When the difference between the ambient temperature and the set temperature is small, it means that the current ambient temperature is close to the set temperature and there is no need to cool down quickly. At this time, the first air guide plate 152 is set horizontally or tilted upward to prevent cold air from blowing directly downward and directly onto the user.

[0102] Since the second air guide plate 154 also serves to guide air into the second air duct 113a, the second air guide plate 154 maintains the maximum position, and can guide the air in the first air duct 112a to the second air duct 113a, so that the air in the second air duct 113a can be blown out from the third air outlet 113d.

[0103] Similarly, when the ambient temperature is close to the set temperature, the fan 130 can rotate at a lower speed to ensure that the first air outlet 112c can continuously output cold air. That is, the second speed is lower than the first speed.

[0104] See also Figure 5 In some embodiments, when the air conditioner 100 operates in a strong heating mode, the fan 130 operates at a third speed, the first air guide plate 152 and the second air guide plate 154 open the first air outlet 112c, the panel 116 opens the second air outlet 113c, and the air in the second air duct 113a is blown out of the second air outlet 113c;

[0105] The second air guide plate 154 is located at the maximum angle, and the first air guide plate 152 and the second air guide plate 154 are arranged parallel or tilted downward.

[0106] When the difference between the indoor ambient temperature and the set temperature is large, it means that the current ambient temperature is low, and it is necessary to turn on the strong heating mode to quickly heat up. In the strong heating mode, the indoor environment needs to be heated quickly, and the user needs to quickly feel the heating amount. Here, the second air guide plate 154 is opened to the maximum downward position, and the second air guide plate 154 is parallel to or tilted downward with the first air guide plate 152, so that under the action of the first air guide plate 152 and the second air guide plate 154, the hot air can flow downward, so that the user can feel the hot air, improving the user's comfort.

[0107] Among them, the third speed is a larger speed. In the stage where rapid heating is required, the air can flow from the first air outlet 112c at a larger wind speed to provide more heat to the indoor environment, so that the indoor environment can be heated up quickly and the user's comfort is improved.

[0108] The panel 116 is arranged vertically, so that the wind blown out of the second air outlet 113c can be directed vertically downward. In the strong heating mode, the vertically downward air outlet of the second air outlet 113c can make the user feel a larger air volume, thereby improving the user's comfort.

[0109] See also Figure 6 In some embodiments, when the air conditioner 100 operates in the comfort heating mode, the fan 130 operates at the fourth speed, the first air guide plate 152 and the second air guide plate 154 close the first air outlet 112c, the panel 116 closes the second air outlet 113c, and the wind in the second air duct 113a is blown out from the third air outlet 113d.

[0110] When the difference between the ambient temperature value and the set temperature value is small, it means that the current ambient temperature value is close to the set temperature value and there is no need to quickly heat up. Since hot air is relatively light, hot air naturally goes up. Therefore, even in the comfort heating mode, the first air guide plate 152 and the second air guide plate 154 are closed, so that the wind in the first air duct 112a can all enter the second air duct 113a and blow out from the third air outlet 113d, ensuring that the hot air can blow to the user, so that the ambient temperature value below the room can reach the set temperature value.

[0111] Similarly, when the ambient temperature is close to the set temperature, the fan 130 can rotate at a lower speed to ensure that the first air outlet 112c can continuously output cold air. That is, the fourth speed is lower than the third speed.

[0112] In summary, the air conditioner 100 provided in the embodiment of the present application can switch different air outlet modes according to different needs, effectively improving the discomfort of direct blowing of cold and hot air and the feeling of stuffiness when there is no air flow, thereby improving the comfort of users.

[0113] Based on the same inventive concept, the embodiment of the present application also provides an air outlet control method, which is applied to the above-mentioned air conditioner 100. The specific structure of the air conditioner 100 can refer to the above description and will not be repeated here. The air outlet control method provided in the embodiment of the present application can switch different air outlet modes according to different needs, effectively improve the discomfort of direct blowing of hot and cold air and the feeling of stuffiness when there is no air flow, and improve the comfort of users.

[0114] See also Figure 7 , the specific steps of the air outlet control method are as follows:

[0115] Step S100, obtaining the ambient temperature value.

[0116] The ambient temperature value is the current indoor temperature value, which is the real-time temperature value of the indoor environment. It can be obtained by setting a temperature sensor on the air conditioner 100, or by a temperature detection module in the controller.

[0117] Step S200, obtaining the current operating mode of the air conditioner 100.

[0118] The current mode of the air conditioner 100 can be either a cooling mode or a heating mode. Obtaining the current operating mode of the air conditioner 100 mainly involves obtaining whether the air conditioner 100 is currently in a cooling mode or a heating mode. Since the characteristics of cold air and hot air are different, the positions of the first air guide plate 152 and the second air guide plate 154 in the strong heating mode and the strong cooling mode are also different, and the positions of the first air guide plate 152 and the second air guide plate 154 in the comfortable heating mode and the comfortable cooling mode are also different, so it is necessary to determine whether the air conditioner 100 is operating in a heating mode or a cooling mode.

[0119] Step S300, calculating the difference between the ambient temperature value and the set temperature value.

[0120] The set temperature value is the target temperature value for heating or cooling the air conditioner 100. It can be set by the user according to the current weather each time it is started, or it can be preset when the air conditioner 100 is turned on, or it can be set by the user during the operation of the air conditioner 100.

[0121] To calculate the difference between the ambient temperature and the set temperature, the difference is obtained by subtracting the set temperature from the ambient temperature.

[0122] After the difference is calculated, the relationship between the difference and the preset difference is compared. By comparing the relationship between the difference and the preset difference, it can be judged whether the current ambient temperature value is close to the set temperature value. If the difference is greater than or equal to the set difference, it means that there is a certain gap between the current ambient temperature value and the set temperature value. If the difference is less than the set difference, it means that the current ambient temperature value is close to the set temperature value.

[0123] Step S400: If the current mode of the air conditioner 100 is the cooling mode and the difference is greater than or equal to the preset difference, the first air outlet 112c and the second air outlet 113c are controlled to discharge air.

[0124] Specifically, the fan 130 is controlled to run at a first speed, the first air guide plate 152 and the second air guide plate 154 open the first air outlet 112c, the panel 116 opens the second air outlet 113c, and the wind in the second air duct 113a is blown out from the second air outlet 113c; wherein, the first air guide plate 152 is at the maximum angle, and the second air guide plate 154 is at the maximum angle.

[0125] For the convenience of description, step S400 is defined as a strong cooling mode. If the difference between the indoor ambient temperature and the set temperature is large, it means that the current ambient temperature is far from the set temperature. At this time, the user's comfort is reflected in the need for rapid cooling or heating so that the indoor ambient temperature can quickly reach the set temperature. In this case, whether it is direct blowing or not is not considered, and rapid cooling or rapid heating is mainly used, that is, the air conditioner 100 runs in a strong mode.

[0126] When the difference is greater than the preset difference, it means that the difference between the indoor ambient temperature and the set temperature is large, and the current ambient temperature is high, and it is necessary to turn on the strong cooling mode to quickly cool down. In the strong cooling mode, the indoor environment needs to be cooled quickly, and the user needs to quickly perceive the cooling capacity. Here, the first air guide plate 152 and the second air guide plate 154 are opened to the maximum position, so that the opening area of ​​the first air outlet 112c is the largest, and the fan 130 runs at the first speed. The wind after cooling by the heat exchanger 120 can be quickly blown out from the first air outlet 112c, so that the indoor ambient temperature can be quickly reduced, improving the user's comfort.

[0127] Among them, the first rotation speed is a relatively large rotation speed. In the stage where rapid cooling is required, the air can flow from the first air outlet 112c at a relatively large wind speed, providing more cooling capacity to the indoor environment, so that the indoor environment can be cooled down quickly and the user's comfort is improved.

[0128] In the strong cooling mode, the panel 116 is arranged vertically, so that the wind blown out of the second air outlet 113c can be directed vertically downward. In the strong cooling mode, the vertical downward air discharge from the second air outlet 113c can enable the user to perceive a larger air volume, thereby improving the user's comfort.

[0129] The fan 130 is not provided in the second air duct 113a, and the wind speed of the wind entering the second air duct 113a from the first air duct 112a comes from the fan 130 provided in the first air duct 112a. After the second air guide plate 154 opens the first air outlet 112c, most of the wind will be blown out from the first air outlet 112c. In order to allow some wind to enter the second air duct 113a, the second air guide plate 154 can be provided at the second air inlet 113b, which can play a certain guiding role, and guide the wind in the first air duct 112a to the second air duct 113a.

[0130] Step S500: if the current mode of the air conditioner 100 is the cooling mode and the difference is less than the preset difference, the first air outlet 112c and the third air outlet 113d are controlled to discharge air.

[0131] Specifically, the fan 130 is controlled to run at the second speed, the first air guide plate 152 and the second air guide plate 154 open the first air outlet 112c, the panel 116 closes the second air outlet 113c, and the air in the second air duct 113a is blown out from the third air outlet 113d.

[0132] The first air guide plate 152 is arranged horizontally or tilted upward, and the second air guide plate 154 is located at a maximum angle.

[0133] For the convenience of description, step S500 is defined as a comfortable cooling mode. If the difference between the indoor ambient temperature and the set temperature is small, it means that the current ambient temperature is close to the set temperature, and the user's body temperature perception is already relatively comfortable. At this time, the user's comfort is reflected in the need to prevent direct blowing. Therefore, the problem of preventing direct blowing needs to be considered here, that is, the air conditioner 100 operates in comfort mode.

[0134] When the difference is smaller than the set difference, it means that the difference between the ambient temperature and the set temperature is small, and the current ambient temperature is close to the set temperature, so there is no need to cool down quickly. At this time, the first air guide plate 152 is set horizontally or tilted upward to prevent cold air from blowing directly downward and directly onto the user.

[0135] Since the second air guide plate 154 also serves to guide air into the second air duct 113a, the second air guide plate 154 maintains the maximum position, and can guide the air in the first air duct 112a to the second air duct 113a, so that the air in the second air duct 113a can be blown out from the third air outlet 113d.

[0136] Similarly, when the ambient temperature is close to the set temperature, the fan 130 can rotate at a lower speed to ensure that the first air outlet 112c can continuously output cold air. That is, the second speed is lower than the first speed.

[0137] Step S600: If the current mode of the air conditioner 100 is the heating mode and the difference is greater than or equal to the preset difference, the first air outlet 112c and the second air outlet 113c are controlled to discharge air.

[0138] The fan 130 is controlled to run at the third speed, the first air guide plate 152 and the second air guide plate 154 open the first air outlet 112c, the panel 116 opens the second air outlet 113c, and the air in the second air duct 113a is blown out of the second air outlet 113c. The second air guide plate 154 is at the maximum angle, and the first air guide plate 152 and the second air guide plate 154 are arranged parallel or tilted downward.

[0139] When the difference is greater than or equal to the preset difference, it means that when the difference between the indoor ambient temperature value and the set temperature value is large, the current ambient temperature value is low, and the strong heating mode needs to be turned on to quickly heat up. In the strong heating mode, the indoor environment needs to be heated quickly, and the user needs to quickly feel the heating amount. Here, the second air guide plate 154 is opened to the maximum downward position, and the second air guide plate 154 is set parallel to or tilted downward with the first air guide plate 152, so that under the action of the first air guide plate 152 and the second air guide plate 154, the hot air can flow downward, so that the user can feel the hot air and improve the user's comfort.

[0140] Among them, the third speed is a larger speed. In the stage where rapid heating is required, the air can flow from the first air outlet 112c at a larger wind speed to provide more heat to the indoor environment, so that the indoor environment can be heated up quickly and the user's comfort is improved.

[0141] The panel 116 is arranged vertically, so that the wind blown out of the second air outlet 113c can be directed vertically downward. In the strong heating mode, the vertically downward air outlet of the second air outlet 113c can make the user feel a larger air volume, thereby improving the user's comfort.

[0142] Step S700: If the current mode of the air conditioner 100 is the heating mode and the difference is less than the preset difference, the first air outlet 112c is controlled to be closed and the third air outlet 113d is controlled to discharge air.

[0143] The fan 130 is controlled to run at the fourth speed, the first air guide plate 152 and the second air guide plate 154 close the first air outlet 112c, the panel 116 closes the second air outlet 113c, and the wind in the second air duct 113a is blown out from the third air outlet 113d.

[0144] When the difference is less than the preset difference, it means that the difference between the ambient temperature value and the set temperature value is small, and the current ambient temperature value is close to the set temperature value, and there is no need to quickly heat up. Since the hot air is relatively light, under natural conditions, the hot air goes up. Therefore, even in the comfort heating mode, the first air guide plate 152 and the second air guide plate 154 are closed, so that the wind in the first air duct 112a can all enter the second air duct 113a and blow out from the third air outlet 113d, ensuring that the hot air can blow to the user, so that the ambient temperature value below the room can reach the set temperature value.

[0145] Similarly, when the ambient temperature is close to the set temperature, the fan 130 can rotate at a lower speed to ensure that the first air outlet 112c can continuously output cold air. That is, the fourth speed is lower than the third speed.

[0146] In addition, the air conditioner 100 also includes a controller, which is used to execute a computer program to implement the above-mentioned air outlet control method. The controller can be an integrated circuit chip with signal processing capabilities. The controller can be integrated on the air conditioner 100. The above-mentioned controller can be a general processor, including a central processing unit (CPU), or a single-chip microcomputer, a microcontroller unit (MCU), a complex programmable logic device (CPLD), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), an embedded ARM and other chips. The controller can implement or execute the disclosed methods, steps and logic block diagrams in the embodiments of the present invention.

[0147] In a feasible implementation, the air conditioner 100 may further include a memory for storing program instructions executable by the controller. The memory may be an independent external memory, including but not limited to a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), and an electrically erasable read-only memory (EEPROM). The memory may also be integrated with the controller, for example, the memory may be integrated with the controller in the same chip.
