[0014] In one embodiment, the two driven gears are rotatably and coaxially connected.

[0015] In one embodiment, both the first rotating member and the second rotating member include a connecting portion and a wind guiding portion connected to each other.

When the first rotating member is in the position where the reduced diameter section is not constructed and the first air mixing opening is in the closed state, the air after heat exchange with the heat exchanger can directly flow out through the air outlet passage, enabling the user to enjoy an obvious cool or warm feeling. When the first air mixing opening is opened and the first rotating member rotates to the position where the reduced diameter section is formed, due to the Venturi effect, the air after heat exchange with the heat exchanger flows through the reduced diameter section, the flow rate will gradually increase, and the pressure will gradually decrease, thereby forming a pressure difference, and indoor air entering the housing from the air mixing inlet can be sucked through the first air mixing opening. After these two parts of air are mixed, the temperature difference between the air flowing out of the air conditioner and the indoor air can be reduced. In this way, even if the air blown out by the air conditioner directly blows towards the user, the user will not feel an obvious temperature difference, which is beneficial to improving the user's comfort.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, then such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0040] The present utility model provides an air conditioner. Among them, the product corresponding to the air conditioner can be an integrated air conditioner, a split air conditioner, or an indoor unit of a split air conditioner.

[0041] Please refer to Figures 1 to 6 , in an embodiment of the present utility model, the air conditioner includes:

[0042] A casing 100, the casing 100 includes a first wall body 110 and a second wall body 120 that are opposite and spaced apart. An air outlet channel 101 is formed between the first wall body 110 and the second wall body 120. The casing 100 is provided with a mixed air inlet communicating with the indoor environment. The first wall body 110 is provided with an openable and closable first mixed air passage 111. The air outlet channel 101 is communicably connected to the mixed air inlet through the first mixed air passage 111 in a switchable manner; and

[0043] A first rotating member 210, rotatably connected to the second wall body 120 and disposed opposite to the first mixed air passage 111, such that the air outlet channel 101 can form a variable diameter section 102, and the variable diameter section 102 is tapered in the air outlet direction.

[0044] It can be understood that the indoor air entering from the self-mixing air inlet does not pass through the heat exchanger on its path to the first mixing air passage 111, so that the air flowing into the air outlet passage 101 from the first mixing air passage 111 is maintained at the temperature of the indoor environment. After the air is heat-exchanged with the heat exchanger and flows into the air outlet passage 101, it is mixed with the air flowing in from the first mixing air passage 111, which can make the temperature of the air flowing out of the air outlet passage 101 closer to the temperature of the indoor environment.

[0045] In the technical solution of the present utility model, since the first rotating member 210 is rotatably connected to the first wall 110, and in addition, the first mixing air passage 111 can be switched between opening and closing, the user can choose whether to construct the reduced-diameter section 102 and open or close the first mixing air passage 111. When the first rotating member 210 is in the position where the reduced-diameter section 102 is not constructed and the first mixing air passage 111 is in the closed state, the air heat-exchanged with the heat exchanger can directly flow out through the air outlet passage 101, enabling the user to enjoy an obvious sense of coolness or heat. When the first mixing air passage 111 is opened and the first rotating member 210 rotates to the position where the reduced-diameter section 102 is formed, due to the Venturi effect, the air heat-exchanged with the heat exchanger flows through the reduced-diameter section 102, the flow rate will gradually increase, and the pressure will gradually decrease, thereby forming a pressure difference, and the indoor air entering the casing 100 from the self-mixing air inlet can be sucked through the first mixing air passage 111. After these two parts of air are mixed, the temperature difference between the air flowing out of the air conditioner and the indoor air can be reduced. In this way, even if the air blown out by the air conditioner blows directly at the user, the user will not feel an obvious temperature difference, which is beneficial to improving the user's comfort.

[0046] Further, in this embodiment, please refer to Figures 1 to 6, the housing 100 further includes a second rotating member 220. The second rotating member 220 is rotatably connected to the first wall body 110 and can open and close to cover the first air mixing opening 111. The reduced diameter section 102 is formed between the first rotating member 210 and the second rotating member 220. It can be understood that the first wall body 110 and the second wall body 120 are oppositely arranged in the width direction of the air outlet passage 101, and the first rotating member 210 and the second rotating member 220 will also be oppositely arranged in the width direction of the air outlet passage 101. In this way, the reduced diameter section 102 can be formed by the first rotating member 210 and the second rotating member 220 rotating towards each other, which is beneficial to improving the symmetry of the reduced diameter section 102 in the width direction of the air outlet passage 101, enhancing the effect of increasing the flow velocity of the air flowing through the reduced diameter section 102, thereby increasing the pressure difference between the reduced diameter section 102 and the outside, forcing the indoor air to flow into the air outlet passage 101 from the first air mixing inlet 131. In addition, it is also beneficial to improve the flow uniformity of the air in the reduced diameter section 102 and avoid generating noise. Of course, in other embodiments, it may also be that only the first rotating member 210 is provided, and an inclined section inclined towards the second wall body 120 is provided at the position of the first wall body 110 relative to the first rotating member 210, and the relatively symmetrical reduced diameter section 102 is formed by the cooperation of the inclined section and the first rotating member 210.

[0047] Further, in this embodiment, please refer to Figures 1 to 6 , the second wall body 120 is provided with a second air mixing opening 121. The first rotating member 210 can open and close to cover the second air mixing opening 121. The air mixing inlet can communicate with the air outlet passage 101 through the second air mixing opening 121. In this way, the air mixing inlet path in the housing 100 can be increased, thereby increasing the amount of air mixed into the air outlet passage 101, further reducing the temperature difference between the air flowing out of the air conditioner and the indoor air, and further improving the comfort of the user. At the same time, corresponding air mixing openings are provided on both sides of the air outlet passage 101 in the width direction, which is beneficial to ensuring the symmetry of the air outlet passage 101 in the width direction, and further ensuring the flow uniformity of the air in the air outlet passage 101. Of course, in other embodiments, only the first air mixing opening 111 may be provided.

[0048] Without loss of generality, the air conditioner includes a wall-mounted indoor unit. The housing 100 is disposed in the indoor unit. An air inlet 103 is provided at the top of the housing 100, and the air inlet 103 communicates with the air outlet passage 101. Among them, a first air mixing inlet 131 can be formed at the air inlet 103, a second air mixing inlet 132 can be formed at the front side of the housing 100, and a third air mixing inlet 133 can be formed at the bottom of the housing 100. It can be understood that in the wall-mounted indoor unit, the air outlet passage 101 is disposed close to the bottom of the housing 100. One of the first wall body 110 and the second wall body 120 is disposed towards the bottom of the housing 100, and the air mixing through hole provided thereon can communicate with the third air mixing inlet 133. The other is disposed towards the top and the front side of the housing 100, and the air mixing through hole provided thereon can communicate with the first air mixing inlet 131 and the second air mixing inlet 132. Without loss of generality, the first wall body 110 is on the lower side. Thus, the first air mixing through hole 111 can communicate with the first air mixing inlet 131 and the second air mixing inlet 132, and the second air mixing through hole 121 can communicate with the third air mixing inlet 133. It should be noted that only one or both of the first air mixing inlet 131 and the second air mixing inlet 132 can be provided. When the first air mixing inlet 131 is provided, the first air mixing inlet 131 is in the area of the air inlet 103 close to the front, which is convenient for the flow path between the first air mixing inlet 131 and the first air mixing through hole 111 to avoid the heat exchanger. Of course, when only the first air mixing through hole 111 is provided, an air mixing inlet can be provided on the corresponding side of the first air mixing through hole 111.

[0049] Further, in this embodiment, please refer to Figures 7 to 9 , the air conditioner further includes a driving device 300 and a transmission link 400. The transmission link 400 has a first rotating end 401 and a second rotating end 402. The driving device 300 is drivingly connected to the first rotating end 401, and the second rotating end 402 is rotatably connected to one of the first rotating member 210 and the second rotating member 220. The link mechanism has a simple structure, can effectively transmit energy, and can accurately control the movement. The driving device 300 drives the first rotating member 210 or the second rotating member 220 through the transmission link 400, which can enable the first rotating member 210 or the second rotating member 220 to accurately open and close the corresponding air mixing through hole and form a variable-diameter section 102 with a suitable shape, which is beneficial to ensuring the air mixing effect in the air outlet passage 101, thereby ensuring the comfort of the user. Of course, in other embodiments, it can also be that different driving devices 300 directly drive the first rotating member 210 and the second rotating member 220 to rotate.

[0050] Further, in this embodiment, please refer to Figures 7 to 9, there are two driving connecting rods 400. The second rotating ends 402 of the two driving connecting rods 400 are respectively rotatably connected to the first rotating member 210 and the second rotating member 220, and the driving device 300 is drivingly connected to the first rotating ends 401 of the two driving connecting rods 400. In this way, the first rotating member 210 and the second rotating member 220 can be driven by the same driving device 300 through different link mechanisms. While ensuring the movement accuracy of the first rotating member 210 and the second rotating member 220, the movement synchronization of the first rotating member 210 and the second rotating member 220 can also be ensured, which is beneficial to accurately realizing the opening and closing of the air mixing inlet and the structure of the variable diameter section 102. Of course, in other embodiments, it may also be that different driving devices 300 are respectively provided corresponding to the first rotating member 210 and the second rotating member 220. The different driving devices 300 may be that both drive the corresponding rotating member through a link mechanism, or one drives one of the first rotating member 210 and the second rotating member 220 through a link mechanism, and the other drives the other of the first rotating member 210 and the second rotating member 220 through other means.

[0051] Further, in this embodiment, please refer to Figures 7 to 9 , the air conditioner further includes a driving gear 510, a transmission gear 520 and two driven gears 530. The driving device 300 is drivingly connected to the driving gear 510. The driving gear 510 is meshed with one of the driven gears 530. The transmission gear 520 is meshed between the driving gear 510 and the other driven gear 530. The first rotating ends 401 of the two driving connecting rods 400 are respectively fixedly connected to the two driven gears 530. Among them, the first rotating end 401 of the driving connecting rod 400 can be integrally formed with the driven wheel or detachably fixedly connected to the driven wheel.

[0052] Specifically, after the driving device 300 drives the driving gear 510 to rotate, the rotation direction of the driven gear 530 directly meshed and connected to the driving gear 510 is opposite to that of the driving gear 510. The rotation direction of the driven gear 530 indirectly transmission-connected to the driving gear 510 through the transmission gear 520 is the same as that of the driving gear 510. Thus, the rotation directions between the two driven gears 530 are opposite. When the two transmission linkages 400 are set to the same structure, the two first rotating members 210 and the second rotating member 220 can be driven to rotate in opposite directions. In this way, when the first rotating member 210 covers the second air mixing opening 121 and the second rotating member 220 covers the first air mixing opening 111, when the first rotating member 210 and the second rotating member 220 rotate in opposite directions, the first rotating member 210 and the second rotating member 220 can swing towards each other into the air outlet channel 101, so as to simultaneously open the first air mixing opening 111 and the second air mixing opening 121, and simultaneously form the reduced-diameter section 102. When the air mixing mode is cancelled, the first rotating member 210 and the second rotating member 220 can swing away from each other to simultaneously cover the first air mixing opening 111 and the second air mixing opening 121.

[0053] Of course, in other embodiments, the conversion of the rotation direction can also be achieved by other means. For example, the first rotation ends 401 of the two transmission linkages 400 are both fixedly connected to the output end of the driving device 300, so that the first rotation ends 401 of the two transmission linkages 400 rotate in the same direction. By setting different numbers of sub-linkages 410 inside the two transmission linkages 400 and adjusting the positions of the rotation connection points between the sub-linkages 410, the second rotation ends 402 of the two transmission linkages 400 rotate in opposite directions, thereby driving the first rotating member 210 and the second rotating member 220 to rotate in opposite directions.

[0054] Furthermore, by adjusting the transmission ratio between the driving gear 510 and different driven gears 530, or adjusting the structures of the two transmission linkages 400, the opening angles of the first rotating member 210 and the second rotating member 220 can be controlled to be the same or different. If the transmission ratios between the driving gear 510 and different driven gears 530 are the same, and the structures of the two transmission linkages 400 are the same, then the first rotating member 210 and the second rotating member 220 can have the same rotation speed, and finally the opening angles of the first rotating member 210 and the second rotating member 220 are also the same; if the transmission ratios between the driving gear 510 and different driven gears 530 are different, or the structures of the two transmission linkages 400 are configured to be different structures, then the first rotating member 210 and the second rotating member 220 can have different rotation speeds, and finally the opening angles of the first rotating member 210 and the second rotating member 220 are also different.

[0055] Furthermore, in this embodiment, please refer to Figures 7 to 9, the two driven gears 530 are rotatably coaxially connected. It can be understood that the coaxial connection means that the rotation axes of the two driven gears 530 are colinear. Specifically, one of the driven gears 530 may form an axial hole at the rotation center, and the other driven gear 530 may form an axial protrusion at the rotation center accordingly. Through the rotatable cooperation between the axial protrusion and the axial hole, the two driven gears 530 are rotatably coaxially connected. In this way, the degree of centralized distribution of the intermediate transmission structure of the driving device 300 and the first rotating member 210 and the second rotating member 220 can be improved, which is beneficial to the layout of the driving device 300 and the related transmission structure. At the same time, the two driven gears 530 can provide support to each other, thereby improving the rotation stability of the two driven gears 530. Of course, in other embodiments, the two driven gears 530 may also be staggered so that the two driven gears 530 are close to the corresponding rotating member to reduce the length of the transmission connecting rod 400 between them and the corresponding rotating member.

[0056] Further, in this embodiment, please refer to Figure 7 and Figure 8 The first rotating member 210 and the second rotating member 220 both include a connecting portion 201 and an air guide portion 202 connected to each other, the first rotating end 401 is rotatably connected to one end of the connecting portion 201 away from the air guide portion 202, the connecting portion 201 and the air guide portion 202 are connected at an angle, and are rotatably connected to the corresponding first wall body 110 or the second wall body 120 through the connection between the two, the angle is an obtuse angle facing away from the opening of the air outlet channel 101, the air guide portion 202 is plate-shaped, and is adapted to the corresponding first air mixing outlet 111 or the second air mixing outlet 121. Specifically, the connection between the air guide portion 202 and the connection portion 201 is located at one side edge of the corresponding air mixing port in the air outlet direction, and the side edge of the air guide portion 202 away from the connection portion 201 can abut against the other side edge of the air mixing port in the air outlet direction to cover the air mixing port, and the connection portion 201 extends obliquely relative to the air guide portion 202 in the direction away from the air outlet channel 101, which will not interfere with the air guide portion 202 covering the air mixing port or rotating into the air outlet channel 101, and can facilitate the connection of the second rotating end 402 of the transmission connecting rod 400. Among them, the air mixing port should be a long strip port extending along the length direction of the air outlet, and the air guide portion 202 is correspondingly a long strip plate structure, and the connection portion 201 is set as a rod-shaped structure like the transmission connecting rod 400, so as to save the material consumption of the rotating part and reduce the weight of the rotating part, so as to drive the rotating part to rotate more effortlessly. Of course, in other embodiments, the rotating member may only be provided with the air guide portion 202, and the second rotating end 402 of the transmission connecting rod 400 may be rotatably connected to the end side of the air guide portion 202, so as to not block the air inlet of the air mixing port while driving the rotating member to rotate.

[0057] Further, in this embodiment, please refer to Figure 7 and Figure 8 , the transmission link 400 includes a plurality of sub-links 410 that are rotatably connected. In this way, the transmission path can be reasonably planned by adjusting the number of sub-links 410, the length of sub-links 410, and the distribution of the rotational connection positions between different sub-links 410, so as to accurately and reliably drive the first rotating member 210 and the second rotating member 220 to rotate. Of course, in other embodiments, the transmission link 400 may also be provided with only one link.

[0058] Further, in this embodiment, please refer to Figures 1 to 6 , the first air mixing opening 111 is disposed corresponding to the middle section or the end of the air outlet passage 101. Specifically, when the first air mixing opening 111 is disposed corresponding to the middle section of the air outlet passage 101, the first wall 110 is distributed on both sides of the first air mixing opening 111. When the first air mixing opening 111 is disposed corresponding to the end of the air outlet passage 101, with reference to the air outlet direction, the first wall 110 is distributed upstream of the first air mixing opening 111, and there is no first wall 110 downstream, that is, the first air mixing opening 111 is disposed on the outlet side of the air outlet passage 101. It can be understood that when the second wall 120 is provided with a second air mixing opening 121, the second air mixing opening 121 is opposite to the first air mixing opening 111. Among them, the first air mixing opening 111 should not be too close to the inlet side of the air outlet passage 101, so as to provide a certain buffer section for the air flow entering the air outlet passage 101, so that more air flow can enter the air outlet passage 101 to ensure the air volume of the air conditioner.

[0059] Further, in this embodiment, please refer to Figure 3 and Figure 6, the opening angle of the first rotating member 210 relative to the second wall 120 into the air outlet passage 101 is the first angle α1, and the opening angle of the second rotating member 220 relative to the first wall 110 into the air outlet passage 101 is the second angle α2. The first angle α1 and / or the second angle α2 is / are from 0 degree to 70 degrees. The first angle α1 and the second angle α2 can be the same angle or different angles. The inclination angles of the first rotating member 210 and the second rotating member 220 within the above range are more appropriate, and can form a reduced-diameter section 102 with a certain inclination degree, so that the flowing air can be subjected to sufficient flow velocity boosting effect, thereby providing sufficient pressure difference. Moreover, it will not bring excessive resistance due to the excessive inclination angles of the first rotating member 210 and the second rotating member 220, which is beneficial to ensuring the smooth flow of the air. When the range of the first angle α1 and the second angle α2 is between 30 degrees and 50 degrees, the above effect is better. Of course, in other embodiments, if the requirement of increasing the flow velocity can be met, the opening angles of the first rotating member 210 and the second rotating member 220 can also be between 70 degrees and 90 degrees, but it is not advisable to be too close to 90 degrees.

[0060] Further, in this embodiment, please refer to Figure 3 and Figure 6 , the width of the air passage formed after the first rotating member 210 opens the second air mixing opening 121 is K1, and the width of the air passage formed after the second rotating member 220 opens the first air mixing opening 111 is K2. The range of K1 is from 2 mm to 35 mm, and the range of K2 is from 2 mm to 35 mm. Among them, the values of K1 and K2 can be equal or unequal. It can be understood that the width of the air passage is the distance between the corresponding rotating member and the wall structure of the casing 100, and this width determines the air passage ability at the air mixing opening. In this embodiment, the first air mixing opening 111 and the second air mixing opening 121 are within the above range, so that the air outlet passage 101 can suck in sufficient indoor air, thereby ensuring the air mixing effect in the air outlet passage 101, making the air flowing out of the air conditioner more conform to the indoor environmental temperature, and thus ensuring the comfort of the user. It can be understood that this width is related to both the width of the air mixing opening and the opening angle of the rotating member. On the premise of corresponding to the above range of the opening angle of the rotating member, the width of the air mixing opening can be designed so that the width of the air passage can meet the above range. Of course, in other embodiments, if the air mixing effect of the air conditioner can be met, other values can also be selected for the above width, either less than 2 mm or greater than 35 mm is acceptable.

[0061] Further, in this embodiment, please refer to Figure 2 and Figure 4When the first air mixing opening 111 is closed, the width of the air outlet channel 101 at the inlet is L1, and the width at the outlet is L2. The minimum width of the diameter-changing section 102 is L0, where 0.2L1 ≤ L0 ≤ 0.75L1 and 0.2L2 ≤ L0 ≤ 0.75L2. In this way, it can ensure that the diameter-changing section 102 has a sufficient degree of gradual contraction, so as to provide sufficient flow velocity enhancement effect for the air flow passing through the diameter-changing section 102, so as to ensure the formation of sufficient pressure difference, so that the air outlet channel 101 can suck enough indoor air through the air mixing opening, thereby ensuring the air mixing effect in the air outlet channel 101.

[0062] Without loss of generality, the air conditioner can be configured with an air mixing mode and a non-air mixing mode. Further, the air mixing mode can also be configured with multiple gears, so that users can choose whether to start the air mixing mode and different gears of the air mixing mode according to their needs. Furthermore, the air conditioner can also be configured with a comfortable air supply mode. The air conditioner can compare the detected indoor environmental temperature with the target temperature set by the user, and adaptively adopt different air supply strategies according to the difference between the two temperatures.

[0063] In an embodiment, when the air conditioner starts in the cooling mode, if the above temperature difference value is within ±1 degree, the air mixing mode is not enabled, and the air deflector 600 at the air outlet is controlled to tilt downward at an angle γ relative to the horizontal plane. At this time, the angle range of γ is 0° to 20°, so as to play a certain role in lifting the cold air and avoid direct blowing of the cold air.

[0064] If the above temperature difference value exceeds ±1 degree but is within ±2 degrees, the angle range of the angle γ at which the air deflector 600 at the air outlet is tilted downward relative to the horizontal plane is 5° to 50°, and the first gear of the air mixing mode is turned on, and the first rotating member 210 and the second rotating member 220 are both controlled to open a certain angle into the air outlet duct.

[0065] If the above temperature difference value exceeds ±2 degrees, the angle range of the angle γ at which the air deflector 600 at the air outlet is tilted downward relative to the horizontal plane is 5° to 50°, and the second gear of the air mixing mode is turned on, and the first rotating member 210 and the second rotating member 220 are both controlled to open a certain angle into the air outlet duct, and the opening angle at this time is larger than the opening angle of the first gear.

[0066] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural transformations made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
