[0006] The distance between the first detection member and the user is obtained, and the rotating speed of the fan is obtained;

[0007] According to the distance between the first detection member and the user and the rotating speed of the fan, the deflection angle and the deflection direction of the guide vane are adjusted.

[0008] The control method of the air conditioner can detect the distance between the first detection member and the user and the rotating speed of the fan in real time, and timely adjust the guide vane according to the distance between the first detection member and the user and the rotating speed of the fan, so as to timely change the blowing direction. The deflection angle of the guide vane can be flexibly set according to the distance and the rotating speed, so as to avoid the user in front of the air conditioner from being directly blown by cold air or hot air, and the anti-straight blowing effect is good.

[0009] In one embodiment, the step of adjusting the deflection angle and the deflection direction of the guide vane according to the distance between the first detection member and the user and the rotating speed of the fan comprises: obtaining a deflection coefficient of the guide vane according to the distance between the first detection member and the user; and adjusting the deflection angle of the guide vane according to the deflection coefficient and the rotating speed of the fan.

[0010] In one embodiment, the deflection coefficient is Ω, the rotating speed of the fan is V, and the deflection angle θ of the guide vane is Ω*V.

[0011] In one of the embodiments, the deflection coefficient of the air guide member gradually decreases as the distance between the first detection member and the user gradually increases.

[0012] In one of the embodiments, the housing has at least one air outlet, and each air outlet is provided with the air guide member. The control method of the air conditioner further comprises the following step: adjusting the deflection direction of the air guide member according to the height position of the air outlet.

[0013] In one of the embodiments, the step of adjusting the deflection direction of the air guide member according to the height position of the air outlet comprises: adjusting the deflection direction of the air guide member corresponding to each air outlet according to the instruction issued by the user when each air outlet is located at the same height position; controlling each air guide member to deflect upward when the user issues a quick cooling instruction; and controlling each air guide member to deflect downward when the user issues a quick heating instruction.

[0014] In one of the embodiments, the step of adjusting the deflection direction of the air guide member according to the height position of the air outlet further comprises: each air outlet is located at a first height position and a second height position, and the first height position is higher than the second height position; controlling each air guide member located at the first height position to deflect upward, and controlling each air guide member located at the second height position to deflect downward.

[0015] In one of the embodiments, each air outlet is provided with at least two air guide members, and all air guide members corresponding to each air outlet are controlled to deflect synchronously and have the same deflection angle.

[0016] An air conditioner comprises:

[0017] a housing;

[0018] a fan provided in the housing;

[0019] an air guide member provided in the housing;

[0020] a first detection member for detecting the distance between the first detection member and a user;

[0021] a second detection member for detecting the rotating speed of the fan;

[0022] a controller for adjusting the deflection angle and the deflection direction of the air guide member according to the distance between the first detection member and the user and the rotating speed of the fan.

[0023] The aforementioned air conditioner can detect the distance between the first detection device and the user, as well as the fan speed, in real time. Based on the distance between the first detection device and the user, and the fan speed, it can adjust the air guide in a timely manner to change the air outlet direction in time, thus preventing users in front of the air conditioner from being directly blown by cold or hot air, and has a good anti-direct-blow effect.

[0038] Reference will now be made to Figures 1 to 3 , the air conditioner comprises a shell 100, a first detection member 200, a fan 300 and a guide member 400 arranged on the shell 100. The control method of the air conditioner in an embodiment comprises the following steps:

[0039] When the user issues a quick cooling or quick heating instruction, the air conditioner automatically switches to the anti-direct blowing mode;

[0040] The distance between the first detection member 200 and the user is obtained, and the rotating speed of the fan 300 is obtained;

[0041] According to the distance between the first detection member 200 and the user and the rotating speed of the fan 300, the deflection angle and the deflection direction of the guide member 400 are adjusted.

[0042] It is to be noted that when the user issues a quick cooling or quick heating instruction, the air conditioner automatically switches to the anti-direct blowing mode, and the air conditioner is in a quick cooling or quick heating state. At this time, the fan 300 operates at the highest rotating speed and is used to provide air volume, and the cold air or hot air is guided out to the indoor by the guide member 400, so as to realize the rapid cooling or rapid heating of the indoor. When the user does not issue a quick cooling or quick heating instruction, the air conditioner will not switch to the anti-direct blowing mode, and the user needs to control to switch to the anti-direct blowing mode.

[0043] Here, reference is made to Figure 4 and Figure 5 . The distance between the first detection member 200 and the user is defined as the straight-line distance between the first detection member 200 and the head of the user, and the distance between the first detection member 200 and the user is also the distance between the air conditioner and the user. The deflection angle of the guide member 400 is defined as the included angle between the extension direction (along the X direction shown in Figure 1 ) of the guide member 400 and the axis direction (along the Y direction shown in Figure 1 ) of the shell 100.

[0044] The control method of the air conditioner can detect the distance between the first detection member 200 and the user and the rotating speed of the fan 300 in real time, and timely adjust the air guide member 400 according to the distance between the first detection member 200 and the user and the rotating speed of the fan 300, so that the air outlet direction can be timely changed, and the deflection angle of the air guide member 400 can be flexibly set according to the distance and the rotating speed, thereby avoiding the user in front of the air conditioner from being directly blown by cold air or hot air, and achieving good direct blowing prevention effect.

[0045] In the embodiment, the first detection member 200 is arranged at the top of the shell 100, and the first detection member 200 is an infrared sensor capable of sensing the presence of the user and detecting the distance between the first detection member 200 and the user. The number of the first detection member 200 is not limited to one. In other embodiments, the first detection member 200 can also be arranged at the bottom of the shell 100, and the first detection member 200 can also be other types of distance detection elements. Herein, the position, type and number of the first detection member 200 are not specifically limited.

[0046] In the embodiment, the number of the air guide member 400 is not limited to one, and each air guide member 400 is in the shape of a rectangular plate. In other embodiments, the air guide member 400 can also be in the shape of a circular plate or other shapes. Herein, the number and shape of the air guide member 400 are not specifically limited.

[0047] For reference Figure 3 According to the distance between the first detection member 200 and the user and the rotating speed of the fan 300, the step of adjusting the deflection angle and the deflection direction of the air guide member 400 includes:

[0048] According to the distance between the first detection member 200 and the user, the deflection coefficient of the air guide member 400 is obtained; and according to the deflection coefficient and the rotating speed of the fan 300, the deflection angle of the air guide member 400 is adjusted.

[0049] It should be noted that when the distance between the first detection member 200 and the user is different, the deflection coefficient of the air guide member 400 is also different, and at this time, the deflection angle of the air guide member 400 can be correspondingly changed in combination with the rotating speed of the fan 300, thereby avoiding the air guide member 400 from being fixed at one angle all the time.

[0050] Specifically, for reference Figures 3 to 5 The deflection coefficient is Ω, the rotating speed of the fan 300 is V, and the deflection angle θ of the air guide member 400 is Ω*V.

[0051] It can be understood that the deflection angle of the air guide member 400 is linearly related to the deflection coefficient and the rotation speed of the fan 300. When the deflection coefficient increases, the deflection angle of the air guide member 400 also increases. When the rotation speed of the fan 300 increases, the deflection angle of the air guide member 400 also increases. When the deflection coefficient decreases, the deflection angle of the air guide member 400 also decreases. When the rotation speed of the fan 300 decreases, the deflection angle of the air guide member 400 also decreases.

[0052] Optionally, the deflection coefficient of the air guide member 400 ranges from 0.01 to 0.05.

[0053] For example, when the distance between the first detection member 200 and the user is 4 m, the deflection coefficient Ω of the air guide member 400 is 0.025, and the rotation speed of the fan 300 is 1000 r / min, the deflection angle of the air guide member 400 is 25°.

[0054] In this embodiment, please refer to Figure 3 When the distance between the first detection member 200 and the user gradually increases, the deflection coefficient of the air guide member 400 gradually decreases.

[0055] It can be understood that when the distance between the first detection member 200 and the user gradually increases, that is, the user is farther away from the air conditioner, the angle between the line connecting the head of the user and the first detection member 200 and the axis direction of the shell 100 is smaller, that is, the deflection angle of the air guide member 400 required is smaller, and accordingly, the deflection coefficient of the air guide member 400 is smaller.

[0056] In this embodiment, the distance L between the first detection member 200 and the user and the deflection coefficient of the air guide member 400 have the following corresponding relationship shown in Table 1:

[0057] Table 1

[0058] Distance L / m 0～2 3 4 5 6 >6 Deflection coefficient Ω 0.05 0.03 0.025 0.02 0.015 0.01

[0059] For example, in Table 1, when the distance L between the first detection member 200 and the user is 0-2 m, the deflection coefficient is 0.05; when the distance L between the first detection member 200 and the user is 3 m, the deflection coefficient is 0.03; when the distance L between the first detection member 200 and the user is 4 m, the deflection coefficient is 0.025; when the distance L between the first detection member 200 and the user is 5 m, the deflection coefficient is 0.02; when the distance L between the first detection member 200 and the user is 6 m, the deflection coefficient is 0.015; and when the distance L between the first detection member 200 and the user is greater than 6 m, the deflection coefficient is 0.01.

[0060] In other embodiments, the distance L between the first detection member 200 and the user and the deflection coefficient of the air guide member 400 can also have other numerical value corresponding relationships.

[0061] Please refer to Figure 3 The shell 100 has at least one air outlet 101, and each air outlet 101 is provided with a guide vane 400 corresponding thereto. The control method of the air conditioner further comprises the following steps:

[0062] According to the height position of the air outlet 101, the deflection direction of the guide vane 400 is adjusted.

[0063] It should be noted that the shell 100 has at least one air outlet 101, which can be understood as having one air outlet 101 or at least two air outlets 101. Through the above setting, according to the height position of the air outlet 101, the deflection direction of the guide vane 400 is adjusted, which can make the air outlet direction of each air outlet 101 optimal, thereby enhancing the direct blowing prevention effect.

[0064] Specific to some embodiments, please refer to Figure 3 The step of adjusting the deflection direction of the guide vane 400 according to the height position of the air outlet 101 comprises:

[0065] When each air outlet 101 is located at the same height position, the deflection direction of the guide vane 400 corresponding to each air outlet 101 is adjusted according to the instruction issued by the user; when the user issues a rapid cooling instruction, the guide vanes 400 are controlled to deflect upward; when the user issues a rapid heating instruction, the guide vanes 400 are controlled to deflect downward.

[0066] It can be understood that when each air outlet 101 is located at the same height position, when the user issues a rapid cooling instruction, the guide vanes 400 are controlled to deflect upward, so that the cold air blows upward to make the gas better fill the indoor space; when the user issues a rapid heating instruction, the guide vanes 400 are controlled to deflect downward, so that the warm air first blows to the ground and moves to the upper part of the indoor space due to its low density characteristics, thereby filling the indoor space.

[0067] For example, please refer to Figure 3 At the first height position, only one air outlet 101 is provided, and when the user issues a rapid cooling instruction, the guide vane 400 at the air outlet 101 is controlled to deflect upward; when the user issues a rapid heating instruction, the guide vane 400 at the air outlet 101 is controlled to deflect downward.

[0068] For another example, please refer to Figure 3 At the first height position, at least two air outlets 101 are provided, and when the user issues a rapid cooling instruction, the guide vanes 400 corresponding to each air outlet 101 are controlled to deflect upward; when the user issues a rapid heating instruction, the guide vanes 400 corresponding to each air outlet 101 are controlled to deflect downward.

[0069] Specific to other embodiments, please refer to Figure 3 The step of adjusting the deflection direction of the guide vane 400 according to the height position of the air outlet 101 further comprises:

[0070] Each air outlet 101 is located at a first height position and a second height position, the first height position is higher than the second height position, the air deflector 400 located at the first height position is controlled to deflect upward, and the air deflector 400 located at the second height position is controlled to deflect downward.

[0071] It can be understood that the air deflector 400 located at the first height position is controlled to deflect upward, and the air deflector 400 located at the second height position is controlled to deflect downward, so that the wind can only blow to the area above the user's head and below the user's legs, avoiding the cold wind or hot wind directly blowing to the temperature-sensitive area such as the user's head, and improving the user's experience.

[0072] For example, referring to Figure 3 , one air outlet 101 is arranged at the first height position, and one air outlet 101 is arranged at the second height position, the air deflector 400 corresponding to the air outlet 101 at the first height position is controlled to deflect upward, and the air deflector 400 corresponding to the air outlet 101 at the second height position is controlled to deflect downward.

[0073] For another example, referring to Figure 3 , at least two air outlets 101 are arranged at the first height position, and at least two air outlets 101 are arranged at the second height position, the air deflectors 400 corresponding to the air outlets 101 at the first height position are controlled to deflect upward, and the air deflectors 400 corresponding to the air outlets 101 at the second height position are controlled to deflect downward.

[0074] Please refer to Figures 3 to 5 , at least two air deflectors 400 are arranged corresponding to each air outlet 101, and all the air deflectors 400 corresponding to each air outlet 101 are controlled to deflect synchronously and have the same deflection angle.

[0075] Here, synchronous deflection can be understood as rotating at the same speed and keeping the same direction. Controlling all the air deflectors 400 corresponding to each air outlet 101 to deflect synchronously and have the same deflection angle can make the air outlet of each air outlet 101 more uniform.

[0076] In this embodiment, the shapes of all the air deflectors 400 corresponding to the same air outlet 101 are the same. In other embodiments, the shapes of all the air deflectors 400 corresponding to the same air outlet 101 can also be different.

[0077] Please refer to Figure 3The air conditioner in an embodiment comprises a shell 100, a fan 300, a wind guide 400, a first detection member 200, a second detection member, and a controller.

The controller is configured to adjust the deflection angle and the deflection direction of the wind guide 400 according to the distance between the first detection member 200 and the user and the rotating speed of the fan 300.

[0078] It can be understood that when the user issues a quick cooling or quick heating instruction, the air conditioner automatically switches to the anti-direct blowing mode, and the air conditioner is in the quick cooling or quick heating state. At this time, the fan 300 operates at the highest rotating speed and is configured to provide air volume. The cold air or hot air is guided out to the indoor by the wind guide 400, so as to realize the quick cooling or quick heating of the indoor.

[0079] The air conditioner described above can detect the distance between the first detection member 200 and the user and the rotating speed of the fan 300 in real time, and timely adjust the wind guide 400 according to the distance between the first detection member 200 and the user and the rotating speed of the fan 300. The air conditioner can timely change the air outlet direction, avoid the user in front of the air conditioner from being directly blown by the cold air or hot air, and has good anti-direct blowing effect.

[0080] In the embodiment, the second detection member is arranged on the output shaft of the fan 300. The second detection member is a sensor, and the number of the second detection member is not limited to one. Herein, the position, type, and number of the second detection member are not specifically limited.

[0081] Specifically, referring to Figure 3 The air conditioner further comprises a first driving member and a first transmission member. The first transmission member is connected with the wind guide 400. The first driving member is configured to drive the first transmission member to move and drive the wind guide 400 to deflect.

[0082] It should be noted that the first driving member is in transmission connection with the first transmission member. The first driving member drives the first transmission member to move, and the first transmission member moves to drive the wind guide 400 to deflect.

[0083] In the embodiment, the first driving member is a motor. The motor can be a stepping motor or other types of driving motors. Herein, the type of the motor is not specifically limited.

[0084] In the embodiment, the first transmission member can be a gear rack or other types of transmission structures. Herein, the specific structural form of the first transmission member is not limited.

[0085] Further, referring to Figure 3The air conditioner further comprises an air duct 500 and a grille 600, the air duct 500 is arranged between the shell 100 and the air fan 300 and is used for guiding air, and the grille 600 is arranged at the air outlet 101 of the shell 100 and is located outside the air guiding member 400, the grille 600 can play the effect of protecting the air guiding member 400 and guiding air.

[0086] Any combination of the technical features in the above-described embodiments can be made, and to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combination of the technical features does not exist, it should be considered that it is within the scope of the description.

[0087] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application.
