Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, for example, to an air guide component and an air conditioner indoor unit. Background Art

[0002] With the development of the times and the advancement of technology, users not only expect air conditioners to have faster cooling and heating speeds, but also pay more and more attention to the comfort performance of air conditioners. No wind feeling and comfortable wind are two problems currently faced. No wind feeling means that when the air conditioner is running, the hot and cold winds avoid the human body. When cooling, the cold wind blows toward the ceiling. Due to the high density of the cold wind, it forms convection with the indoor air, and the cold wind avoids the human body and accelerates the reduction of the indoor temperature; when heating, the hot wind blows toward the floor. Due to the low density of the hot wind, it can form convection with the upper air, and the hot wind avoids the human body and accelerates the increase of the indoor temperature. Since the wind of ordinary air conditioners is blown out directly after passing through the heat exchanger, the temperature of the wind directly blowing to the human body is too low or too high, which is easy to cause discomfort. Therefore, comfortable wind means that even if the air conditioner blows directly to the human body, it will not make people feel uncomfortable without affecting the room temperature adjustment speed, avoiding discomfort caused by excessively cold or overheated wind.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art: it is impossible to have both a windless and comfortable wind air supply mode. Summary of the invention

[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] The embodiments of the present disclosure provide an air guide component and an air conditioner indoor unit to solve the problem that an air supply mode cannot have both a windless feeling and a comfortable wind feeling.

[0006] In some embodiments, the air guide component includes: a main body plate, provided with a hollow portion; an air guide swing blade assembly, including a rotating shaft and a swing blade arranged on the rotating shaft, and the swing blade is arranged in the hollow portion of the main body plate; and a first driving member, used to drive the swing blade to rotate relative to the main body plate, wherein the first driving member includes a stepping motor and a transmission rod, and the transmission rod is engaged with the rotating shaft.

[0007] In some embodiments, the air conditioner indoor unit includes the air guide component provided in the aforementioned embodiments.

[0008] The air guide component and the air conditioner indoor unit provided by the embodiments of the present disclosure can achieve the following technical effects:

[0009] During cooling, the first driving member drives the swing blade to rotate, thereby increasing the upward air supply angle, so that the cold air is blown out in a higher and farther direction. During heating, the first driving member drives the swing blade to increase the downward air supply angle, so that the hot air is blown out in a lower direction, thereby realizing an air supply mode without wind feeling. In addition, during cooling or heating air supply, the first driving member drives the swing blade to rotate relative to the main plate, and the high-speed cold air or hot air blown out forms a negative pressure near the hollow part, which attracts normal temperature air to pass through the hollow part and mix with the hot air or cold air to form comfortable wind with suitable temperature, thereby realizing the comfortable wind air supply mode, thereby improving the comfort of users.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0030] Combination Figures 1 to 6 As shown, an embodiment of the present disclosure provides an air guide component, including a main body plate 10, which is provided with a hollow portion 101; an air guide swing blade assembly, including a rotating shaft 30 and a swing blade 20 arranged on the rotating shaft, and the swing blade 20 is arranged in the hollow portion 101 of the main body plate; and a first driving member, which is used to drive the swing blade to rotate relative to the main body plate, wherein the first driving member includes a stepping motor 40 and a transmission rod 50, and the transmission rod 50 is engaged with the rotating shaft 30.

[0031] With the above embodiment, during cooling, the first driving member drives the swing blade to rotate, increasing the upward air supply angle so that the cold air is blown out in a higher and farther direction. During heating, the first driving member drives the swing blade to increase the downward air supply angle so that the hot air is blown out in a lower direction, thereby realizing a windless air supply mode. In addition, during cooling or heating air supply, the first driving member drives the swing blade to rotate relative to the main plate, and the cold air or hot air forms a negative pressure in the hollow part, attracting air at normal temperature to pass through the hollow part and mix with the hot air or cold air to form a comfortable wind with a suitable temperature, thereby realizing a comfortable wind air supply mode, thereby improving the user's comfort.

[0032] Optionally, the main body plate 10 is provided with a plurality of hollow portions 101 that are evenly spaced. Figure 3 In this way, when the cold wind or hot wind forms negative pressure in the hollow part 101, the main plate 10 is evenly stressed, and the normal temperature air passes through the hollow part 101 and is evenly mixed with the hot wind or cold wind, ensuring that the airflow blowing toward the human body is comfortable wind with a suitable temperature.

[0033] Optionally, the axes of the multiple hollow portions 101 are partially or completely parallel. When the axes of the multiple hollow portions 101 are partially parallel, the axes of some of the hollow portions 101 are not parallel. For example, the axis of the hollow portion 101 located in the middle of the main plate 10 is parallel to the cross-section of the main plate 10; the axes of the hollow portions 101 located on both sides of the main plate 10 are set at a certain angle to the cross-section of the main plate 10, that is, they are not parallel to the axis of the hollow portion 101 located in the middle of the main plate 10, and the axes of the hollow portions 101 located at both ends of the main plate 10 are inclined from the middle of the main plate 10 to the outside. In this way, it is helpful to cooperate with the swing blades to guide the airflow output and expand the air supply range of the airflow. The "axis" in the embodiment of the present disclosure can be understood as the symmetrical dividing line of the hollow portion. Combined with Figure 3 As shown, the main body plate 10 is provided with 6 hollow parts, wherein the two middle hollow parts are parallel to the cross section of the main body plate 10, the two left hollow parts are inclined to the left, and the two right hollow parts are inclined to the right.

[0034] Alternatively, if Figure 1 As shown, the rotating shaft 30 is arranged on the windward side of the main body plate 10. In this way, when the main body plate is closed, the whole is beautiful and neat. The first driving member drives the rotating shaft to rotate, so that the swing blade on the rotating shaft rotates, thereby adjusting the blowing angle of the wind from the hollow part through the swing blade.

[0035] Optionally, the rotating shaft 30 is arranged perpendicular to the cross section of the main plate 10, and the length of the rotating shaft 30 is greater than the distance between the hollow parts 101 at both ends of the main plate 10. In this way, the rotating shaft can better drive the swing blade to rotate and adjust the blowing angle of the wind from the hollow part 101.

[0036] Optionally, the swing blade 20 is attached to the windward side of the main body plate 10, or to the leeward side of the main body plate 10, or is located in the hollow portion 101 and is attached to the inner wall of the hollow portion 101. In the case where the swing blade is attached to the windward side or the leeward side of the main body plate, the area of ​​the windward side of the swing blade is larger than the area of ​​the hollow portion. In this way, the angle at which the wind blows out of the hollow portion can be adjusted. In actual applications, users can choose to use according to actual conditions. Optionally, the number of the swing blades 20 is multiple. Optionally, the swing blade is duck-tongue-shaped, such as Figure 4 shown.

[0037] Optionally, the swing blade 20 rotates upward clockwise at an angle of 0 to 60° relative to the main body plate 10, and rotates downward counterclockwise at an angle of 0 to 60°. In this way, windless air supply can be better achieved, thereby improving the air comfort of users.

[0038] Optionally, the swing blade 20 fits with the hollow portion 101. In this way, when the swing blade fits with the hollow portion, that is, the swing blade is located in the hollow portion and the side wall of the swing blade fits with the inner side wall of the hollow portion, on the one hand, it is beautiful and neat, and on the other hand, during the production process, the hollow portion of the main plate can be realized by stamping technology, and the stamped material can be used as the swing blade, which helps to save materials and reduce production costs. In addition, when the swing blade fits with the hollow portion, it helps to reduce the abnormal sound generated by the airflow passing through the gap between the swing blade and the hollow portion.

[0039] Optionally, a plurality of swing blades 20 are evenly spaced and arranged on the rotating shaft 30. In this way, based on the evenly spaced arrangement of the swing blades and the hollow portion, the airflow flows evenly through the swing blades and the hollow portion, which is helpful to prevent airflow turbulence and abnormal noise caused by turbulence on the one hand, and is helpful to evenly bear the force on the main plate and the swing blades on the other hand. In addition, it is helpful to evenly supply air.

[0040] Alternatively, if Figure 4 As shown, the swing blade 20 includes: a first swing blade group 201, which is arranged at the first end of the rotating shaft 30; a second swing blade group 202, which is arranged at the second end of the rotating shaft 30; and a third swing blade group 203, which is arranged at the middle of the rotating shaft 30, wherein the swing blades in the first swing blade group 201 and the swing blades in the second swing blade group 202 are arranged tilted relative to the swing blades in the third swing blade group 203. In this way, the airflow output is guided by the swing blades of the first swing blade group 201 and the swing blades of the second swing blade group 202, and the tilting of the swing blades helps to expand the air supply range of the airflow.

[0041] Here, “the blades in the first blade group 201 and the blades in the second blade group 202 are arranged obliquely relative to the blades in the third blade group 203” can be understood as: the first blade group 201, the second blade group 202 and the third blade group 203 are all located in the same plane, the axis of the blades in the first blade group 201 and the axis of the blades in the third blade group 203 form a certain angle, and the blades in the first blade group 201 are arranged obliquely from the third blade group 203 to the end of the main plate 10, such as Figure 4 The swing blades in the first swing blade group are tilted to the left; similarly, the axis of the swing blades of the second swing blade group 202 is at a certain angle to the axis of the swing blades of the third swing blade group 203, and the swing blades of the second swing blade group 202 are tilted from the third swing blade group 203 to the other end of the main plate 10, as shown in FIG. Figure 4 The swing blades in the second swing blade group are shown to be tilted to the right. Similarly, the "axis line" in the embodiment of the present disclosure can be understood as the symmetry dividing line of the swing blades.

[0042] Optionally, the first swing blade group 201 and the second swing blade group 202 are symmetrically arranged. This helps to expand the air supply range of the airflow. For example, in actual application, the swing blades of the first swing blade group 201 supply air to the left area of ​​the main plate 10, the swing blades of the second swing blade group 202 supply air to the right area of ​​the main plate 10, and the swing blades of the third swing blade group 203 supply air to the front of the main plate 10 along the air supply direction of the main plate 10.

[0043] Optionally, the first swing blade group 201 includes one or more first swing blades. The axes of the multiple first swing blades in the first swing blade group 201 are parallel; the second swing blade group 202 includes one or more second swing blades. The axes of the multiple second swing blades in the second swing blade group 202 are parallel; the third swing blade group 203 includes one or more third swing blades. The axes of the multiple third swing blades in the third swing blade group 203 are parallel. In this way, it is helpful to evenly supply air and prevent airflow turbulence.

[0044] The stepper motor drives the rotating shaft to rotate through the transmission rod, which effectively ensures the rotation of the swing blades, thereby adjusting the blowing angle of the wind from the hollow part. Among them, the transmission rod and the rotating shaft are engaged by gears to achieve transmission. Optionally, the transmission rod is arranged vertically to the rotating shaft. When the transmission rod and the rotating shaft are arranged vertically, the transmission rod and the rotating shaft can be driven by bevel gears. Optionally, the transmission rod is arranged parallel to the rotating shaft. When the transmission rod and the rotating shaft are arranged parallel, the transmission rod and the rotating shaft can be driven by spur gears. The stepper motor and the transmission rod are both located on the windward side of the main body plate, so that when the main body plate is closed, the stepper motor and the transmission rod are both located on the inner side of the main body plate, which is beautiful and neat.

[0045] Optionally, combined Figure 2 As shown, the stepper motor 40 includes a motor output shaft 60 , on which a motor output gear 601 is disposed, and the transmission rod 50 includes a first end and a second end opposite to each other, and the first end is provided with a first transmission gear 501 , wherein the motor output gear 601 is meshed with the first transmission gear 501 .

[0046] The motor output gear is fixedly or detachably connected to the motor output shaft and rotates synchronously with the motor output shaft. The motor output gear is meshed with the first transmission gear of the transmission rod, and when the motor output gear rotates, the first transmission gear rotates under the drive of the motor output gear. The first transmission gear is fixedly or detachably connected to the end of the transmission rod, and the transmission rod rotates synchronously with the first transmission gear. Optionally, the motor output gear is arranged at the end of the motor output shaft. Optionally, the motor output gear is arranged in the middle of the motor output shaft. Optionally, the first transmission gear is arranged at the end of the transmission rod. In this way, it helps to avoid interference between the transmission rod and the motor output shaft after assembly.

[0047] Optionally, the motor output shaft is arranged in parallel with the transmission rod. In the case where the motor output shaft is arranged in parallel with the transmission rod, the motor output gear and the first transmission gear may both be spur gears. Optionally, the motor output shaft is arranged perpendicular to the transmission rod. In the case where the motor output shaft is arranged perpendicular to the transmission rod, the motor output gear and the first transmission gear may both be bevel gears.

[0048] Combination Figure 2 and Figure 5 As shown, the motor output shaft 60 is vertically arranged with the transmission rod 50, and the transmission rod 50 is vertically arranged with the rotating shaft 30. The two ends of the transmission rod 50 are respectively engaged with the motor output shaft 60 and the rotating shaft 30, and the transmission rod 50 is fixed under the clamping of the motor output shaft 60 and the rotating shaft 30. In this way, it is helpful to maintain the transmission between the motor output shaft, the transmission rod and the rotating shaft.

[0049] Optionally, the first driving member further comprises a support frame for supporting the transmission rod, and the transmission shaft passes through a bearing seat at the end of the support frame. The support frame is located in the middle of the transmission rod, which is conducive to avoiding bending of the transmission rod and improving the stability of the transmission rod.

[0050] The transmission rod decelerates the speed of the stepper motor and outputs it to the rotating shaft to prevent the rotating shaft from rotating too fast, which will reduce the accuracy of the swing angle of the swing blades and thus reduce the comfort of the user. When the stepper motor 40 rotates forward, the swing blades rotate downward relative to the main plate 10 to increase the downward air supply angle; when the stepper motor 40 rotates reversely, the swing blades rotate upward relative to the main plate 10 to increase the upward air supply angle and play a role in lifting the wind.

[0051] Optionally, the greater the transmission ratio between the motor output gear and the first transmission gear, the slower the rotation speed of the rotating shaft. In this way, the swing blade can be adjusted to different swing angles, so that the airflow flows out more stably, improving the air comfort of the user.

[0052] Optionally, combined Figure 2 As shown, the second end of the transmission rod 50 is provided with a second transmission gear 502 , and the rotating shaft 30 is provided with a rotating shaft gear 301 , wherein the rotating shaft gear 301 is meshed with the second transmission gear 502 .

[0053] The second transmission gear is meshed with the rotating shaft gear, so that the transmission rod drives the rotating shaft to rotate. Optionally, the second transmission gear and the rotating shaft gear are both bevel gears. Optionally, the second transmission gear and the rotating shaft gear have the same number of teeth. In this way, the rotating shaft and the transmission rod have the same rotation speed. Optionally, the greater the transmission ratio between the second transmission gear and the rotating shaft gear, the slower the rotation speed of the rotating shaft. In this way, the swing blade is adjusted to different swing angles by the rotating shaft, which improves the accuracy of the swing angle of the swing blade, makes the airflow flow out more stably, and improves the comfort of the user.

[0054] Optionally, the second transmission gear is disposed at the end of the transmission rod. In this way, interference between the transmission rod and the rotating shaft is avoided. Optionally, the first transmission gear and the second transmission gear have the same number of teeth. In this way, the input rotation speed and the output rotation speed of the transmission rod are the same, which is conducive to improving the stability of the transmission rod.

[0055] Optionally, the air guide member further includes: a second driving member for driving the main plate 10 to rotate. In this way, the second driving member drives the main plate 10 to rotate, adjusts the air supply area of ​​the main plate 10, realizes large-area air supply, and quickly cools down or heats up the room.

[0056] In practical applications, when the second driving member drives the main plate 10 to be closed and non-rotating, the first driving member can drive the swing blade 20 to rotate toward the leeward side of the main plate 10 to achieve small-area air supply, which helps to reduce the discomfort caused by large-area airflow output to the human body. When the swing blade 20 rotates to form a certain angle with the windward side of the main plate 10, the second driving member drives the main plate 10 to rotate, which helps to fully mix the normal temperature air with the cold air or hot air of the hollow part 101, and keeps the output airflow at a more suitable temperature without affecting the cooling / heating effect, so that the human body feels comfortable.

[0057] In practical applications, such as Figure 7 As shown, during cooling, the second driving member drives the main plate 10 to open, and then the first driving member drives the swing blade 20 to rotate upward to the maximum angle. At this time, the cold air is blown out from the hollow portion 101 along the swing blade to a higher and farther direction, realizing a windless air supply mode. Figure 8 As shown, when heating, the second driving member drives the main panel 10 to open to the maximum angle, and then drives the swing blade 20 to rotate downward to the maximum angle through the first driving member. At this time, the hot air is blown out from the hollow part 101 along the swing blade 20 to a lower direction, realizing a windless air supply mode.

[0058] Optionally, the second driving member includes: a main plate motor (not shown in the figure), and a swing arm 100 connected to the main plate, wherein the main plate motor is electrically connected to the swing arm. In this way, the rotation of the main plate 10 can be better realized, and the stability of the main plate 10 during rotation can be improved. The swing arm is driven to rotate by the main plate motor, so that the swing arm drives the main plate 10 to rotate, thereby achieving the purpose of rotating the main plate 10.

[0059] Alternatively, if Figure 1As shown, the swing arm includes a first swing arm 100 and / or a second swing arm 200. The first swing arm 100 and the second swing arm 200 are respectively arranged at both ends of the windward surface of the main body plate 10, and the first swing arm 100 or the second swing arm 200 is connected to the motor of the main body plate 10. In this way, when the motor of the main body plate drives the first swing arm, the second swing arm is driven to rotate through the main body plate 10, so that the first swing arm 100 and the second swing arm 200 can be synchronously moved, and can also play a role in supporting the main body plate 10.

[0060] Optionally, the first swing arm 100 and the second swing arm 200 are symmetrically arranged, which helps to evenly apply force to the main plate 10 .

[0061] Optionally, the swing arm is an arc-shaped structure. Optionally, the swing arm is a V-shaped structure. Optionally, the arm body of the swing arm connected to the main board motor is a straight arm, and the arm body connected to the main board is arc-shaped. One end of the swing arm is connected to the output shaft of the main board motor, and the other end is connected to the windward surface of the main board 10. Among them, the openings formed at both ends of the assembled swing arm are set downward. In this way, the opening angle of the main board 10 can be better expanded to achieve large-area air supply, and the airflow can be guided to blow out in a lower direction during heating.

[0062] Optionally, the stepper motor is fixedly connected to the swing arm. This helps to improve the stability of the gear transmission between the stepper motor, the transmission member and the rotating shaft. The stepper motor is set on the side wall of the swing arm through a fastener. Optionally, the stepper motor is set at the curved end of the swing arm. In this way, a certain preset distance is left between the stepper motor and the main plate, which is conducive to setting the transmission rod. Optionally, combined with Figure 5 As shown, the stepper motor 40 is arranged on the side wall of the curved end of the first swing arm 100. This is conducive to improving the installation stability of the stepper motor. Among them, the motor output gear and the rotating shaft gear are located in the same plane. This is conducive to the stability of the gear transmission and the stability of the transmission rod. In addition, it is conducive to the overall appearance and neatness.

[0063] Alternatively, if Figure 1 As shown, the air guide component also includes: a rotating shaft support 80, which is used to pass the rotating shaft 30. In this way, the rotating shaft is supported by the rotating shaft support 80 to prevent the rotating shaft 30 from bending. Optionally, the rotating shaft support 80 can be arranged in the middle of the rotating shaft 30, or at the end of the rotating shaft 30. In the case where there is one rotating shaft support, the rotating shaft support is arranged in the middle of the rotating shaft. In the case where there are multiple rotating shaft supports, at least one rotating shaft support is respectively provided at both ends of the rotating shaft. Other rotating shaft supports are arranged at intervals on the rotating shaft. In this way, it helps to prevent the rotating shaft from bending due to excessive length, which is beneficial to ensure the straightness of the rotating shaft.

[0064] Optionally, the rotating shaft support 80 may be a bearing seat, wherein the base of the bearing seat is detachably connected to the windward surface of the main plate 10 or the side wall of the swing arm, and the rotating shaft 30 is passed through the bearing seat and rotates relative to the bearing seat under the drive of the first driving member.

[0065] Alternatively, if Figure 5 As shown, the first swing arm and / or the second swing arm include a first extension arm and a second extension arm that are bent and connected, such as a "7" shape, wherein the stepper motor 40 is arranged at the bending connection between the first extension arm and the second extension arm of the first swing arm, and the rotating shaft support 80 is arranged at the end of the first extension arm or the second extension arm. In this way, the stepper motor 40 and the rotating shaft support 80 are both arranged on the first swing arm, so that the distance between the stepper motor 40 and the rotating shaft support 80 is relatively fixed, thereby further improving the transmission stability of the transmission rod 50.

[0066] Optionally, the rotating shaft support is fixedly connected to the swing arm, which is helpful to improve the stability of the meshing transmission between the rotating shaft gear and the second transmission gear.

[0067] Optionally, one side of the rotating shaft support is fixedly connected to the side wall of the swing arm, and the other side is provided with a rotating shaft. The swing arm and the rotating shaft are arranged on two opposite sides of the rotating shaft support. Optionally, the bottom of the rotating shaft support is in contact with the windward surface of the main body plate. Optionally, a certain distance is left between the bottom of the rotating shaft support and the windward surface of the main body plate. Optionally, the bottom of the rotating shaft support is fixedly connected or detachably connected to the windward surface of the main body plate. In this way, it is conducive to further fixing the rotating shaft support and improving the installation stability of the rotating shaft support. In addition, it is conducive to overall beauty and neatness.

[0068] Alternatively, if Figure 1 As shown, the wind guide swing blade assembly also includes: a rotating shaft fixing member 70, which is used to fix the swing blade 20 to the rotating shaft 30.
