Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a foldable air guide mechanism, an air conditioner, and an air guide control method. Background Art

[0002] With the continuous advancement of science and technology and people's pursuit of comfortable quality of life, air conditioners, as key equipment for indoor environment regulation, are undergoing continuous development and innovation. At present, the air conditioning industry is committed to achieving the goals of higher efficiency, intelligence, environmental protection and health. This transformation not only reflects the trend of technological innovation, but also reflects the society's emphasis on green sustainable development and healthy life.

[0003] The comfort of air conditioning airflow is one of the important criteria for measuring the performance of healthy air conditioning. The air supply of traditional air conditioners blows directly to the human body, which can easily cause discomfort symptoms such as colds, headaches and joint pain. In recent years, with the continuous improvement of comfort and health requirements and the development of intelligent control technology, higher requirements have been placed on the diversification and flexibility of air supply modes of air conditioners.

[0004] At present, most air conditioners on the market have only one air outlet. No matter what operating mode the air conditioner is in, the air can only be blown out from this single air outlet. Although some air conditioners can adjust the air supply direction to a certain extent by controlling the rotation of the air guide plate at the edge of the air outlet through a driving mechanism, the size of the air guide plate and the working space are limited to the position near the air outlet due to the limitation of the size of the air outlet. This design can usually only change the air supply direction to a limited number of directions, its flexibility and versatility are limited, and the air guide efficiency is not high. The limitations of the existing technology in the direction and mode of air supply can no longer fully meet the continuous improvement of modern users' demands for comfort and personalization. Therefore, the development of a more flexible and intelligent air supply system can provide users with a better user experience and has broad application prospects. Summary of the invention

[0049] At present, most air conditioners on the market have only one air outlet. No matter what operating mode the air conditioner is in, the wind can only be blown out from this single air outlet. Although some air conditioners can adjust the air supply direction to a certain extent by controlling the rotation of the air guide plate at the edge of the air outlet through a driving mechanism, the size of the air guide plate and the working space are limited to the position near the air outlet due to the limitation of the size of the air outlet. This design can usually only change the air supply direction to a limited number of directions, its flexibility and versatility are limited, and the air guiding efficiency is not high. The limitations of the prior art in the direction and mode of air supply can no longer fully meet the continuous improvement of modern users' demands for comfort and personalization. Therefore, the development of a more flexible and intelligent air supply system can provide users with a better user experience and has broad application prospects. Therefore, based on the above requirements, the present embodiment provides a foldable air guide mechanism 100.

[0050] See also Figures 1 to 13 The present embodiment discloses a foldable air guide mechanism 100, which is arranged at the air outlet of the air conditioner 200, wherein the air conditioner 200 can be an integrated air conditioner or a split air conditioner. When the air conditioner 200 is a split air conditioner, the indoor unit can be a vertical indoor unit or a wall-mounted indoor unit.

[0051] The foldable air guide mechanism 100 comprises: a left connecting rod assembly 2, a right connecting rod assembly 3 and an air guide plate assembly 4;

[0052] The inner large ends of the left-side connecting rod assembly 2 and the right-side connecting rod assembly 3 are hinged to the air conditioner 200, specifically the inner wall of the air outlet of the air conditioner shell 1, and the outer large ends are hinged to the air guide plate assembly 4. The left-side connecting rod assembly 2 and the right-side connecting rod assembly 3 are both foldable and telescopic structures. When the left-side connecting rod assembly 2 and the right-side connecting rod assembly 3 are synchronously extended and retracted and stay in different folded states, the air guide plate assembly 4 is synchronously driven to present different air guiding states.

[0053] In the foldable air guide mechanism 100 of the present embodiment, the left connecting rod assembly 2 and the right connecting rod assembly 3 of the foldable and telescopic structure work together to drive the air guide plate assembly 4. On the one hand, the air guide plate assembly 4 can be driven to extend outside the air outlet to obtain a larger adjustment space. On the other hand, the air guide plate assembly 4 extending outside the air outlet can more flexibly adjust the output wind direction. Compared with the existing method of setting an air guide plate at the air outlet, it is more flexible to adjust, has more diverse air guide modes, and more intelligent air conditioning, which can significantly improve the user experience. As shown in Figure 4, at this time, the left connecting rod assembly 2 and the right connecting rod assembly 3 are both in a folded and contracted state. At this time, the corresponding air guide plate assembly 4 covers the air outlet, as shown in Figure 4. Figure 5 As shown, at this time, the left connecting rod assembly 2 and the right connecting rod assembly 3 drive the air guide plate assembly 4 to extend out of the air outlet and guide the air output by the air conditioner upward, as shown in FIG. Figure 7 As shown, at this time, the air guide plate assembly 4 guides the output wind downward.

[0054] Please refer again Figure 2 and Figure 5The left side connecting rod assembly 2 includes: a first connecting rod 21, a second connecting rod 22, a first driving unit 23 and a second driving unit 24; the small end of the first connecting rod 21 is hinged to the small end of the second connecting rod 22, the driving end of the first driving unit 23 is connected to the large end of the first connecting rod 21, the second driving unit 24 is connected to the large end of the second connecting rod 22, and the driving end of the second driving unit 24 is connected to the air deflector assembly 4. The housing of the first driving unit 23 is fixedly connected to the housing 1 of the air conditioner 200, and its driving end is connected to the large end of the first connecting rod 21, so the first driving unit 23 can drive the rotation angle of the first connecting rod 21, and can simultaneously drive the angle of the second connecting rod 22, and the driving end of the second driving unit 24 is connected to the air deflector assembly 4, so the second driving unit 24 can drive the air deflector assembly 4 to rotate compared with the second connecting rod 22. In summary, the left connecting rod assembly 2 can drive the air guide plate assembly 4 to extend out of the air outlet or retract to the air outlet, and can also adjust the rotation angle of the air guide plate assembly 4 to change the wind direction of the output wind, so that the output wind is delivered to the environment in different forms and angles, so that the human body has different air-conditioning experiences.

[0055] It should be noted that the inner side or outer side mentioned in this embodiment are compared with the inner and outer sides of the air outlet, the direction closer to the inside of the air outlet is the inner side, and the direction away from the air outlet is the outer side.

[0056] like Figure 2 As shown, the right connecting rod assembly 3 includes: a third connecting rod 31, a fourth connecting rod 32 and a third driving unit 33, wherein the third driving unit 33 is arranged at the hinge of the small ends of the third connecting rod 31 and the fourth connecting rod 32, and the large end of the fourth connecting rod 32 is also connected to the air deflector assembly 4. That is, the housing of the third driving unit 33 and its driving end are respectively connected to one of the third connecting rod 31 and the fourth connecting rod 32, and its function is to drive the relative opening angle between the third connecting rod 31 and the fourth connecting rod 32.

[0057] The inner large end of the third connecting rod 31 is hinged to the housing 1 of the air conditioner 200, and the large end of the fourth connecting rod 32 is hinged to the air guide plate assembly 4. The left connecting rod assembly 2 and the right connecting rod assembly 3 are respectively connected to the two sides of the air guide plate assembly 4 in the length direction of the air outlet. When the foldable air guide mechanism 100 performs the air guide work, the left connecting rod assembly 2 and the right connecting rod assembly 3 act synchronously, so as to more flexibly adjust the angle between the first connecting rod 21, the third connecting rod 31 and the housing 1 of the air conditioner 200, adjust the relative angle between the second connecting rod 22 and the first connecting rod 21, the fourth connecting rod 32 and the third connecting rod 31, and the relative angle between the fourth connecting rod 32 and the second connecting rod 22 and the air guide plate assembly 4.

[0058] In this embodiment, the first drive unit 23 and the second drive unit 24 are arranged on the left connecting rod assembly 2, and the third drive unit 33 is arranged on the right connecting rod assembly 3, so that three groups of drive units cooperate to complete the folding and adjustment process of the air guide plate assembly 4. At the same time, the three drive units are respectively distributed on the left connecting rod assembly 2 and the right connecting rod assembly 3, which can balance the load of the drive unit, facilitate its structural design and connection, and improve the smoothness and stability of the air guide plate assembly 4 and its own folding action.

[0059] It should be noted that in the present embodiment, two connecting rods are provided for constituting the left connecting rod assembly 2 and the right connecting rod assembly 3. In other embodiments, one or more connecting rods may be added according to the extension distance required for the air guide plate assembly 4, and corresponding drive units may be added at the hinge positions of each connecting rod.

[0060] In this embodiment, the first connecting rod 21 and the third connecting rod 31 have the same structure, and the second connecting rod 22 and the fourth connecting rod 32 have the same structure.

[0061] The first connecting rod 21, the second connecting rod 22, the third connecting rod 31 and the fourth connecting rod 32 can be straight connecting rods or curved connecting rods. In this embodiment, the first connecting rod 21, the second connecting rod 22, the third connecting rod 31 and the fourth connecting rod 32 all adopt a connecting rod structure with a small arc, and all have a large end and a small end.

[0062] The first drive unit 23 , the second drive unit 24 and the third drive unit 33 are all servo motors, specifically micro servo motors.

[0063] In order to provide a larger wind guide surface and wind guide angle, the inner side of the wind guide plate assembly 4 is an arc-shaped wind guide surface. The inner side of the wind guide plate assembly 4 refers to the side opposite to the inner side of the air outlet. When the wind guide plate assembly 4 is in a closed state, the wind guide plate assembly 4 can just cover the air outlet. At this time, the air conditioner 200 is in a closed state, and the wind guide plate assembly 4 makes the interior of the housing 1 in a sealed state, which can prevent dust, mosquitoes, etc.

[0064] Please refer again Figure 2 and Figure 3 The wind deflector assembly 4 includes: a first wind deflector 41, a second wind deflector 42, and a fourth driving unit, and the fourth driving unit is used to drive the first wind deflector 41 and the second wind deflector 42 to switch between the stacked state and the unfolded state. That is, the first wind deflector 41 and the second wind deflector 42 have roughly the same structure and size. In the stacked state, the two are superimposed together. When unfolded, one wind deflector is unfolded along its surface relative to the other wind deflector to form a larger wind guide surface.

[0065] Specifically, a locking slide rail structure (not shown in the figure) is further provided between the opposing surfaces of the first air guide plate 41 and the second air guide plate 42, and the fourth driving unit drives the first air guide plate 41 and the second air guide plate 42 to adjust between the stacked state and the unfolded state under the guidance of the locking slide rail structure. The locking slide rail mechanism includes a trapezoidal guide rail and a slide buckle slidably connected to the trapezoidal guide rail, the slide buckle can only slide along the length direction of the trapezoidal guide rail and will not separate from the trapezoidal guide rail, and the trapezoidal guide rail and the slide buckle are respectively fixedly connected to one of the first air guide plate 41 and the second air guide plate 42.

[0066] The fourth driving unit includes: a servo motor 43, a gear 44 connected to the output shaft of the servo motor 43, and a rack 45 meshed with the gear 44, wherein the rack 45 and the servo motor 43 are respectively connected to one of the first air guide plate 41 and the second air guide plate 42. The rotation of the servo motor 43 drives the gear 44 to rotate, so that the rack 45 and the gear 44 undergo a relative displacement change, and synchronously control the first air guide plate 41 and the second air guide plate 42 to be stacked or unfolded, as well as any partial unfolding state between the stacked state and the fully unfolded state.

[0067] In this embodiment, in order to improve the smoothness of the unfolding between the first air deflector 41 and the second air deflector 42, the servo motor 43 is arranged in the middle position of the air deflector assembly 4, and the gear 44 connected to the servo motor 43 is meshed with a transmission shaft 46, and the two ends of the transmission shaft 46 are respectively meshed with a rack 45. The rotation of the servo motor 43 can synchronously drive the rack and gear transmission on both sides, so that the first air deflector 41 and the second air deflector 42 are more smoothly unfolded or stacked. That is, a set of gear and rack combination mechanisms are respectively arranged at the outer ends in the length direction of the first air deflector 41 and the second air deflector 42, and are jointly controlled by the same transmission shaft 46 to achieve its simple and reliable synchronous action.

[0068] The inner side surfaces of the first air guide plate 41 and the second air guide plate 42 are both arc-shaped air guide surfaces.

[0069] Please refer again Figure 1 This embodiment further provides an air conditioner 200, the air outlet of which is provided with a foldable air guide mechanism 100 of any structure as described above.

[0070] Please combine again Figures 5 to 13 The working process of the foldable air guide mechanism 100 or the air guide control method is briefly described below, which includes the following steps:

[0071] According to the control instruction, the folding air guide mechanism of the air conditioner is selected to enter the corresponding air guide mode; the control instruction may come from an instruction issued to the air conditioner by an operating terminal such as a user's remote control, or the air conditioner may autonomously select an instruction to execute according to the control strategy based on the environmental detection signal and the air guide control strategy.

[0072] like Figure 5 As shown, when the air conditioner enters the first air guide mode, the left connecting rod assembly 2 and the right connecting rod assembly 3 drive the air guide plate assembly 4 to extend out of the air outlet of the air conditioner 200, and the inner edge 401 of the air guide plate assembly 4 abuts against the lower edge of the air outlet, so that the wind is output upward. Since the present embodiment adopts a two-stage connecting rod structure as the push-out structure of the air guide plate assembly 4, the air guide of the air conditioner 200 can have more diverse and more accurate modes. When the air conditioner starts to work in the cooling mode, the air guide plate assembly 4 overlaps the arc-shaped air guide surface 7 and the lower edge of the overlapping air outlet through the left connecting rod assembly 2 and the right connecting rod assembly 3, and the cold air flows along the arc-shaped air guide surface 7 toward the upper area of ​​the room. Subsequently, under the trend of its own sedimentation, the cold air can be fully diffused in the height direction of the indoor environment. In addition, through the connecting rod structure, the air guide plate assembly 4 can achieve a wide range of air supply direction adjustment. The above structures cooperate with each other to realize upward and downward sweeping of air. When sweeping air upward and downward, the lower edge of the air guide plate assembly 4 and the air guide channel of the air conditioner always maintains a smooth and continuous overlapping arc surface, so that the cold air is fully diffused in various areas of the indoor environment.

[0073] like Figure 7 As shown, when the air conditioner enters the second air guide mode, the left connecting rod assembly 2 and the right connecting rod assembly 3 drive the air guide plate assembly 4 to extend out of the air outlet, and the outer edge 402 of the air guide plate assembly 4 abuts against the upper edge of the air outlet, so that the wind is output downward. At this time, a downward air guide channel 6 is formed to guide the hot air to flow toward the ground. After that, due to the natural upward trend of the hot air, it can be widely diffused in the vertical direction of the room, ensuring that the hot air is evenly distributed in the entire space. In addition, with the help of the wall effect, the hot air flowing to the ground will continue to diffuse along the ground, which helps to mix the cold and hot air more effectively in the room.

[0074] like Fig. 9As shown, when the air conditioner enters the third air guide mode, the left connecting rod assembly 2 and the right connecting rod assembly 3 drive the air guide plate assembly 4 to extend out of the air outlet, and the air guide plate assembly 4 divides the air outlet into an upper air outlet channel 61 and a lower air outlet channel 62. When the air guide channel blows air, the air guide plate assembly 4 can change the air supply direction so that the air supply direction is changed to different directions, thereby meeting the requirements for different air supply directions, and has strong flexibility. At the same time, the air supply mode of the air conditioner is more diversified, which improves the comfort of the air conditioner and the user experience. The air guide plate assembly 4 divides the air guide channel into an upper air outlet channel 61 and a lower air outlet channel 62, wherein the air guide channel of the upper air outlet channel 61 converges, the wind speed is faster, and the air supply distance is long. The air guide channel of the lower air outlet channel 62 diverges, the wind speed is slower, the air supply range is large, the wind feels gentle, and the comfort is high. In this working mode, a more uniform temperature change in the space can be achieved, improving user comfort.

[0075] like Figure 6 As shown in the steps, when the air conditioner enters the first air guide mode, the first air guide plate 41 and the second air guide plate 42 constituting the air guide plate assembly 4 are in different degrees of expansion. After expansion, the first air guide plate 41 overlaps with the lower edge of the air outlet, and the arc-shaped air guide surface 7 (8) of the air guide plate is expanded, which can extend the upward air guide distance, thereby solving the problem of low air guide efficiency of traditional air guide plates and preventing air conditioning wind from falling to the ground at a close distance and blowing directly on the human body.

[0076] like Figure 8 As shown in the step, when the air conditioner enters the second air guide mode, the first air guide plate 41 and the second air guide plate 42 constituting the air guide plate assembly are in different degrees of expansion. The expanded air guide plate can extend the downward air guide distance and enhance the hot air guide efficiency. This air guide method can more efficiently make the indoor temperature reach the user's set value.

[0077] In the first wind guiding mode, the second wind guiding mode and the third wind guiding mode, the first wind guiding plate 41 and the second wind guiding plate 42 are unfolded to different degrees, which means that the first wind guiding plate 41 and the second wind guiding plate 42 can be partially unfolded or fully unfolded.

[0078] The steps also include, before the folding air guide mechanism of the air conditioner is selected to enter the corresponding air guide mode according to the control instruction: the sensor detects the position of the human body near the air conditioner, and selects the corresponding control instruction according to the position of the human body. The air conditioner also includes a controller (not shown), and the air guide group component 4 includes an infrared sensor (not shown) electrically connected to the controller, and the infrared sensor has a ranging module for detecting the user's position and a module for sensing temperature. The temperature of the human body in the environment can be sensed, and the distance from the high temperature point can be identified to determine the air volume and wind speed of the air outlet of the air conditioner. The temperature control method of the air conditioner in a long-term operation state is adjusted according to the changes in the ambient temperature of the human body and the optimal temperature of the human body.

[0079] The air conditioner 200 also has a precise air supply mode. In this mode, the controller can adjust the angle of the air guide plate in real time according to the position of the human body detected by the infrared sensor, and adjust the wind speed and air volume according to the distance and temperature of the human body, so as to achieve precise air supply to the user's surrounding environment. Specifically, when the air conditioner is in the third working mode, the position of the air guide component is as follows: Fig. 9 As shown, at this time, the air guide channel is divided into an upper air outlet channel 61 and a lower air outlet channel 62. On this basis, when the user needs fixed-point cooling or heating, the size of the upper air outlet channel 61 and the lower air outlet channel 62 can be adjusted by driving the air guide plate group relatively close, such as Fig.10 As shown, or reduce the opening of the wind guide channel to make the wind more concentrated, such as Fig.11 At the same time, in the fixed-point air supply mode, the air conditioner can run at high power, which can quickly adjust the user's surrounding temperature to ensure the user's comfort.

[0080] like Fig.12 As shown, the air conditioner 200 is also in the anti-direct blowing mode, at which time the first air guide plate 41 and the second air guide plate 42 are unfolded through the sliding structure. After unfolding, the lower edge of the first air guide plate 41 can cover the lower edge of the air outlet, and the upper edge of the second air guide plate 42 can cover the upper edge of the air outlet. Fig.12 Preferably, small openings may be provided on the first air guide plate 41 and the second air guide plate 42, and the small openings are exposed only when the first air guide plate 41 and the second air guide plate 42 are unfolded, so as to effectively prevent the human body from being blown directly.

[0081] like Fig.13 As shown, in the full air volume mode, the air guide plate assembly 4 is away from the air guide channel 6, so as to minimize the air loss and improve the cooling and heating effects of the air conditioner.

[0082] The foldable air guide mechanism and air conditioner of this embodiment use a motor to drive a connecting rod device to push out the air guide plate, and use a two-stage connecting rod device so that the air guide plate can work in a more reasonable air guide position and have a more flexible air guide direction; in addition, the air guide plate group can realize the relative movement of the air guide plate through a sliding device, expand the air guide area and improve the air guide effect; multiple air guide plates can cooperate with each other to better guide the air in the air guide channel, so as to improve the effect of adjusting the air outlet direction of the indoor unit, thereby improving the comfort of air outlet. Optimize the air outlet mode and improve the user experience.

[0083] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
