Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an indoor unit air outlet mechanism and an air conditioner. Background Art

[0002] In the prior art, air conditioner indoor units, especially wall-mounted air conditioner indoor units, generally sweep the air up and down through an air guide plate disposed at the air outlet, thereby changing the wind direction of the air outlet. In particular, when the rotation axis of the air guide plate is close to the upper or lower end area of ​​the air outlet, once the air guide plate is rotated outward and opened, the air outlet mechanism of the air conditioner, such as the horizontal air guide blades, will be directly exposed to the user's field of vision, affecting the user experience. Moreover, if the rotation axis of the air guide plate is close to the upper or lower end area of ​​the air outlet, for example, when the air conditioner blows cold air into the room, one side of the air guide plate is the cooler airflow blown out by the air duct, and the other side is the hotter air in the room, and condensation is easily generated on the side of the air guide plate that is not facing the airflow, and if too much condensation accumulates, it will fall off. Utility Model Content

[0003] The first object of the utility model is to provide an indoor unit air outlet mechanism to solve the technical problem that the existing user can directly observe the internal structure of the air duct.

[0004] The utility model provides an indoor unit air outlet mechanism, including an air duct and a wind direction adjustment mechanism, the air duct having an air outlet and a first side wall and a second side wall arranged opposite to each other, the air outlet being the end of the air duct along the air flow direction in the air duct, the first side wall having a first part, the second side wall having a second part, the distance between the first part and the second part gradually decreases along the air flow direction in the air duct, and the distance between the first part and the second part is the smallest at the air outlet; the wind direction adjustment mechanism includes an air guide block arranged between the first side wall and the second side wall, the air guide block divides the part of the air duct into a first sub-duct and a second sub-duct arranged side by side, the first sub-duct is located between the air guide block and the first side wall, and the second sub-duct is located between the air guide block and the second side wall, and the wind direction adjustment mechanism is configured to change the flow area ratio of the first sub-duct to the second sub-duct.

[0005] The beneficial effects brought by the air outlet mechanism of the indoor unit of the utility model are:

[0006] By using an air guide block to divide part of the air duct into a first sub-duct and a second sub-duct arranged side by side, the airflow entering the air duct can flow through the first sub-duct and the second sub-duct respectively, and the wind direction adjustment mechanism is configured to change the flow area ratio of the first sub-duct and the second sub-duct, thereby changing the airflow ratio passing through the two. The first part of the first side wall and the second part of the second side wall are configured to gradually decrease the spacing along the airflow direction in the air duct, which can cause the airflow of the first sub-duct and the airflow of the second sub-duct to merge at the tail of the air guide block. The change in the airflow of the two can also cause the direction of the synthetic airflow to change. Thus, it is possible to guide the air without an external air guide plate. Moreover, since the air guide block is arranged in the air duct, the airflow of the air conditioner indoor unit flows through each surface of the air guide block in the air duct, and there is no obvious difference in cold and hot, so there will be no condensation on the surface of the air guide block in the cooling mode.

[0007] In addition, the distance between the first part and the second part at the air outlet is the smallest, which reduces the width of the air outlet. Since the air guide block is arranged in the air duct, the air guide block can effectively shield the structure in the air duct, preventing the user from observing the air guide plate group inside the air duct or the internal features of the air conditioner, thereby improving the user experience.

[0008] In an optional technical solution, the width of the tail section of the air guide block along the air flow direction in the air duct gradually decreases along the air flow direction in the air duct.

[0009] By setting this part of the air guide block into the above shape, the airflow flowing along the surface of the air guide block can quickly converge when the airflow flows in the first sub-duct and the second sub-duct, so as to make full use of the respective airflow directions of the first sub-duct and the second sub-duct to synthesize the final air outlet direction.

[0010] In an optional technical solution, the air duct further includes a merging area, and the merging area is located between the tail of the air guide block along the air flow direction in the air duct and the air outlet.

[0011] By setting a converging area between the tail of the air guide block and the air outlet, the airflows of the first sub-duct and the second sub-duct can be merged in the converging area. When the airflows merge, they are still inside the air duct, so the converging of the airflows will not be affected by the external flow field, thereby improving the accuracy of airflow control.

[0012] In an optional technical solution, the cross-sectional width of the head of the air guide block along the air flow direction in the air duct gradually increases, and the angle between the surface of the head of the air guide block and the air flow direction in the air duct is smaller than the angle between the surface of the tail of the air guide block and the air flow direction in the air duct.

[0013] By setting the air guide block to the above shape, the head of the air guide block can be used to divert the airflow, and the flow resistance in the airflow diversion is reduced, thereby improving the air outlet efficiency.

[0014] In an optional technical solution, the wind direction adjustment mechanism further includes an adjustment plate, which is movably disposed on the first sub-air duct, and the adjustment plate is used to adjust the flow area of ​​the first sub-air duct.

[0015] By movably setting an adjustment plate in the first sub-duct, the distance between its two edges and the air guide block and the first side wall can be changed during the movement of the adjustment plate, or the distance between one edge of the adjustment plate and the air guide block or the first side wall can be changed, thereby changing the flow area of ​​the first sub-duct, and when the flow area of ​​the second sub-duct remains unchanged, the flow area ratio of the first sub-duct and the second sub-duct is also changed, so the air volume ratio of the first sub-duct and the second sub-duct is changed, and then the air outlet direction of the air conditioner is adjusted. The adjustment plate is movably set in the first sub-duct to adjust the flow area of ​​the first sub-duct, and only the air volume in a smaller area needs to be adjusted to affect the final air outlet direction of the air conditioner, which can achieve a multiplier effect.

[0016] In an optional technical solution, the adjustment plate is rotatably disposed in the first sub-air duct.

[0017] The adjustment plate is installed in a rotating manner. When the adjustment plate rotates, the distance between one edge of the adjustment plate and the air guide block or the first side wall, or the distance between the two edges of the adjustment plate and the air guide block and the first side wall respectively, is generally linearly related to the rotation angle, so it is convenient to control the rotation angle.

[0018] In an optional technical solution, the adjustment plate is movably connected to the first side wall.

[0019] By movably connecting the adjustment plate with the first side wall, it is convenient to install the driving mechanism for driving the adjustment plate in the space outside the air duct to prevent it from affecting the airflow in the air duct. The above arrangement facilitates the arrangement of the driving mechanism.

[0020] In an optional technical solution, the indoor unit air outlet mechanism further includes a sweeping blade group, the swing axis of the sweeping blade group is parallel to or intersects with the width direction of the air duct at an acute angle, and the sweeping blade group is located in the second sub-air duct.

[0021] Since the flow rate in the second sub-duct is fixed compared to that in the first sub-duct, the adjustment plate adjusts the flow area of ​​the first sub-duct. By setting a sweeping blade group in the second sub-duct, the effect of the sweeping blade group on changing the airflow direction is not affected by the adjustment plate adjusting the air volume, thereby improving the sweeping effect of the sweeping blade group.

[0022] In an optional technical solution, the air guide block is fixedly disposed in the air duct, the first side wall and the second side wall are both arc-shaped and convex toward each other, and the surface of the air guide block is arranged at unequal intervals from the first side wall.

[0023] By arranging the first side wall and the second side wall to protrude away from the other, the protruding portions of the first side wall and the second side wall can be used to form a larger cross-sectional width to accommodate the air guide block, so that the provision of the air guide block will not significantly reduce the overall ventilation area of ​​the airflow, making the flow velocity and pressure of the outlet airflow in the air duct more stable, reducing the flow resistance loss of the air duct, and improving the air outlet efficiency.

[0024] The second object of the utility model is to provide an air conditioner to solve the technical problem that the user can directly observe the internal structure of the air duct.

[0025] The utility model provides an air conditioner, which includes an air conditioner indoor unit, the air conditioner indoor unit has an indoor unit panel, the air conditioner indoor unit includes any one of the indoor unit air outlet mechanisms described above, and the air duct is arranged on the indoor unit panel.

[0026] By arranging the above-mentioned indoor unit air outlet mechanism in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned indoor unit air outlet mechanism, which will not be described one by one here. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0039] Embodiment 1:

[0040] Figure 1 A schematic diagram of the structure of the indoor unit air outlet mechanism provided in the first embodiment of the utility model; Figure 2 FIG. 1 is an external schematic diagram of an indoor unit air outlet mechanism provided by the first embodiment of the utility model. Figure 1-Figure 2 As shown, the indoor unit air outlet mechanism provided by the first embodiment of the utility model includes an air duct 100 and an air direction adjustment mechanism 200, the air duct 100 has an air outlet 130 and a first side wall 110 and a second side wall 120 arranged opposite to each other, the air outlet 130 is the end of the air duct 100 along the air flow direction in the air duct, the first side wall 110 has a first part, the second side wall 120 has a second part, the distance between the first part and the second part gradually decreases along the air flow direction in the air duct, and the distance between the first part and the second part at the air outlet 130 is Minimum; the wind direction adjustment mechanism 200 includes an air guide block 210 arranged between the first side wall 110 and the second side wall 120, the air guide block 210 divides a portion of the air duct 100 into a first sub-duct 140 and a second sub-duct 150 arranged side by side, the first sub-duct 140 is located between the air guide block 210 and the first side wall 110, the second sub-duct 150 is located between the air guide block 210 and the second side wall 120, and the wind direction adjustment mechanism 200 is configured to change the flow area ratio of the first sub-duct 140 and the second sub-duct 150.

[0041] It should be noted that the airflow direction in the air duct is a technical term as a whole, which means the direction of the straight line from the center of the entrance of the air duct 100 to the exit of the air duct 100 - the center of the air outlet 130. It is the overall direction of the airflow in the air duct 100, not the airflow direction at any position in the air duct 100.

[0042] This embodiment is described by taking a wall-mounted air conditioner indoor unit as an example. Usually, the air duct 100 of the wall-mounted air conditioner indoor unit is arranged at the front lower part thereof, and accordingly, the air outlet 130 is located at the front lower part of the indoor unit panel 400 of the wall-mounted air conditioner indoor unit. In this application, the front refers to the side of the wall-mounted air conditioner indoor unit facing the main indoor space, and the rear refers to the side of the wall-mounted air conditioner indoor unit facing the wall on which it is hung. The bottom refers to the side of the wall-mounted air conditioner indoor unit facing the ground.

[0043] In the drawings used in this embodiment, the first side wall 110 refers to the lower side wall of the air duct 100, and the second side wall 120 refers to the upper side wall of the air duct 100. However, the first side wall 110 and the second side wall 120 are used in this application to include the solution that the first side wall 110 is the upper side wall of the air duct 100 and the second side wall 120 is the lower side wall of the air duct 100. In particular, in the following text, in the relevant solutions of setting the adjustment plate 220 and setting the wind sweeping blade group 300, the adjustment plate 220 and the wind sweeping blade group 300 can also be set to be in a situation where the positions are reversed from those shown in the figure.

[0044] In addition, the indoor unit air outlet mechanism of the present application can be applied not only to wall-mounted air conditioner indoor units, but also to cabinet air conditioner indoor units or ceiling units. For example, in a cabinet air conditioner indoor unit, the first side wall 110 can be the left side wall or the right side wall of the air duct 100, and correspondingly, the second side wall 120 can be the right side wall or the left side wall of the air duct 100. Similarly, if applied to a ceiling unit, the first side wall 110 can be the lower side wall or the upper side wall of the air duct 100, and correspondingly, the second side wall 120 can be the upper side wall or the lower side wall of the air duct 100.

[0045] The air guide block 210 divides part of the air duct 100 into a first sub-duct 140 and a second sub-duct 150 which are arranged side by side. This means that in a certain local area of ​​the air duct 100 along the direction of the air flow in the air duct, the first sub-duct 140, the air guide block 210 and the second sub-duct 150 are arranged in sequence along the width direction of the air duct 100, and these three are not arranged along or approximately along the direction of the air flow in the air duct.

[0046] The wind direction adjustment mechanism 200 is configured to change the flow area ratio of the first sub-duct 140 and the second sub-duct 150. It can only change the flow area of ​​the first sub-duct 140 without changing the flow area of ​​the second sub-duct 150, or only change the flow area of ​​the second sub-duct 150 without changing the flow area of ​​the first sub-duct 140, or change the flow area of ​​both the first sub-duct 140 and the second sub-duct 150 at the same time.

[0047] The first sub-duct 140 is located between the air guide block 210 and the first side wall 110, and the second sub-duct 150 is located between the air guide block 210 and the second side wall 120. This only illustrates the positions of the first sub-duct 140 and the second sub-duct 150, and does not absolutely mean that the first sub-duct 140 and the second sub-duct 150 are respectively defined by the first sub-duct 140 and the air guide block 210 and the second sub-duct 150 and the air guide block 210, and moreover, it does not mean that the flow areas of the first sub-duct 140 and the second sub-duct 150 are completely determined by the air guide block 210 and the first side wall 110, as well as the second side wall 120.

[0048] The distance between the first part and the second part gradually decreases along the airflow direction in the air duct, and the distance between the first part and the second part is the smallest at the air outlet 130, which means that the distance between the parts of the first side wall 110 and the second side wall 120 close to the air outlet 130 gradually decreases in the direction toward the air outlet 130. In other words, the first part and the second part are the parts of the first side wall 110 and the second side wall 120 that are closer to the air outlet 130, respectively. As for the parts of the first side wall 110 and the second side wall 120 that are far from the air outlet 130, whether the distance gradually increases or decreases along the direction toward the air outlet 130 is not restricted.

[0049] By using the air guide block 210 to divide the part of the air duct 100 into the first sub-duct 140 and the second sub-duct 150 arranged side by side, the airflow entering the air duct 100 can flow through the first sub-duct 140 and the second sub-duct 150 respectively. Moreover, the wind direction adjustment mechanism 200 is configured to change the flow area ratio of the first sub-duct 140 and the second sub-duct 150, thereby changing the airflow ratio passing through the two. The first part of the first side wall 110 and the second part of the second side wall 120 are configured to gradually reduce the spacing along the airflow direction in the air duct, which can promote the airflow of the first sub-duct 140 and the airflow of the second sub-duct 150 to merge at the rear of the air guide block 210. The airflow of the two changes, which can also cause the direction of the synthetic airflow to change. Thus, it is possible to guide the air without an external air guide plate. Moreover, since the air guide block 210 is arranged in the air duct 100, the air outlet air of the air conditioner indoor unit flows through each surface of the air guide block 210 in the air duct 100, and there is no obvious difference in temperature, so condensation will not appear on the surface of the air guide block 210 in the cooling mode.

[0050] In addition, the distance between the first part and the second part at the air outlet 130 is the smallest, which reduces the width of the air outlet 130, and because the air guide block 210 is disposed in the air duct 100, the air guide block 210 can effectively shield the structure in the air duct 100, preventing the user from observing the air guide plate group inside the air duct 100 or the inner features of the air conditioner, thereby improving the user experience. Figure 2 It can be seen that when the user looks toward the air outlet 130 , the specific structure in the air duct 100 is mainly blocked by the air guide block 210 , and the structure of the wind sweeping blade assembly 300 or the entrance position of the air duct 100 or deeper structures cannot be seen.

[0051] Figure 3 The structure diagram of the air guide block in the air outlet mechanism of the indoor unit provided in the first embodiment of the utility model; Figure 1 and Figure 3 As shown, optionally, the width of the tail section of the air guide block 210 along the airflow direction in the air duct gradually decreases along the airflow direction in the air duct.

[0052] The tail of the air guide block 210 along the direction of the air flow in the air duct refers to the part of the air guide block 210 located further downstream in the air flow along the direction of the air flow in the air duct, and is not absolutely and clearly defined as the part of a fixed numerical proportion at the very end of the air guide block 210 in that direction, such as 10% or 20%.

[0053] By setting this part of the air guide block 210 into the above shape, when the airflow flows in the first sub-duct 140 and the second sub-duct 150, the airflow flowing along the surface of the air guide block 210 can quickly converge to make full use of the respective airflow directions of the first sub-duct 140 and the second sub-duct 150 to synthesize the final air outlet direction.

[0054] like Figure 1 As shown, optionally, the air duct 100 further includes a merging area 160 , and the merging area 160 is located between the tail of the air guide block 210 along the air flow direction in the air duct and the air outlet 130 .

[0055] Providing the converging area 160 means that the end of the air guide block 210 along the air flow direction in the air duct is not directly located at the air outlet 130 , but is located inside the air outlet 130 , that is, upstream of the air outlet 130 .

[0056] By setting a confluence area 160 between the tail of the air guide block 210 and the air outlet 130, the airflows of the first sub-duct 140 and the second sub-duct 150 can be converged in the confluence area 160. When the airflows converge, they are still located inside the air duct 100, so the confluence of the airflows will not be affected by the external flow field, thereby improving the accuracy of airflow control.

[0057] like Figure 1 and Figure 3 As shown, optionally, the cross-sectional width of the head of the air guide block 210 along the air flow direction in the air duct gradually increases, and the angle between the surface of the head of the air guide block 210 and the air flow direction in the air duct is smaller than the angle between the surface of the tail of the air guide block 210 and the air flow direction in the air duct.

[0058] The head of the air guide block 210 along the direction of air flow in the air duct refers to the part of the air guide block 210 located further upstream in the air flow along the direction of air flow in the air duct, and is not absolutely limited to a fixed numerical proportion of the uppermost end of the air guide block 210 in that direction, such as 10% or 20%.

[0059] Specifically, the air guide block 210 in this embodiment may be shaped such that the width increases first and then decreases, and more specifically, may be shaped like a water drop. Moreover, the tip of the water drop is oriented toward or approximately toward the upstream side of the airflow direction in the air duct. The blunter end of the water drop is oriented toward or approximately toward the air outlet 130.

[0060] By setting the air guide block 210 to the above shape, the head of the air guide block 210 can be used to divert the airflow, and the flow resistance in the airflow diversion is reduced, thereby improving the air outlet efficiency.

[0061] like Figure 1As shown, optionally, the wind direction adjustment mechanism 200 further includes an adjustment plate 220 , which is movably disposed on the first sub-air duct 140 , and the adjustment plate 220 is used to adjust the flow area of ​​the first sub-air duct 140 .

[0062] The adjustment plate 220 may be a curved plate or a flat plate. In this embodiment, the adjustment plate 220 is a curved plate.

[0063] By movably setting the adjustment plate 220 in the first sub-duct 140, the distance between the two edges of the adjustment plate 220 and the air guide block 210 and the first side wall 110 can be changed during the movement of the adjustment plate 220, or the distance between one edge of the adjustment plate 220 and the air guide block 210 or the first side wall 110 can be changed, thereby changing the flow area of ​​the first sub-duct 140, and when the flow area of ​​the second sub-duct 150 remains unchanged, the flow area ratio of the first sub-duct 140 to the second sub-duct 150 is also changed, so the air volume ratio of the first sub-duct 140 to the second sub-duct 150 is changed, and then the air outlet direction of the air conditioner is adjusted. The adjustment plate 220 is movably set in the first sub-duct 140 to adjust the flow area of ​​the first sub-duct 140, and only the air volume in a smaller area needs to be adjusted to affect the final air outlet direction of the air conditioner, which can achieve a multiplier effect.

[0064] like Figure 1 As shown, optionally, the adjustment plate 220 is rotatably disposed in the first sub-air duct 140 .

[0065] Specifically, the adjustment plate 220 is rotatably connected to the inside of the first sub-air duct 140 . More specifically, one end of the adjustment plate 220 in the width direction is pivotally connected to the inner side surface of the first side wall 110 .

[0066] How to rotatably install a plate whose length direction is parallel to the length direction of the air outlet 130 in an air conditioner, and the relevant specific structure of how to drive the plate to rotate are already known technologies to those skilled in the art and will not be repeated in this application.

[0067] The adjustment plate 220 is installed in a rotating manner. When the adjustment plate 220 rotates, the distance between one edge of the adjustment plate 220 and the air guide block 210 or the first side wall 110, or the distance between two edges of the adjustment plate 220 and the air guide block 210 and the first side wall 110 respectively, is generally linearly related to the rotation angle, so it is easy to control the rotation angle.

[0068] like Figure 1 As shown, optionally, the adjustment plate 220 is movably connected to the first side wall 110 .

[0069] Specifically, in this embodiment, a concave portion 111 is partially provided on one side of the first side wall 110 facing the air guide block 210. When the opening angle of the adjustment plate 220 relative to the first side wall 110 is zero, that is, the width of the first sub-air duct 140 is maximized, that is, the flow area is maximized, the adjustment plate 220 can be completely received in the concave portion 111. The state at this time is as follows: Figure 4 As shown, the plate body portion of the adjustment plate 220 itself will not cause significant interference to the airflow.

[0070] By movably connecting the adjustment plate 220 with the first side wall 110, it is convenient to install the driving mechanism for driving the adjustment plate 220 in the space outside the air duct 100 to prevent it from affecting the airflow in the air duct 100. The above arrangement facilitates the arrangement of the driving mechanism.

[0071] In another implementation, the adjustment plate 220 may be disposed on the air guide block 210, for example, it may be rotatably disposed on the air guide block 210. Alternatively, the adjustment plate 220 may be slidably connected to the air duct 100. Specifically, for example, the sliding direction of the adjustment plate 220 relative to the air duct 100 forms an acute angle or a right angle with the flow direction of the airflow in the first sub-air duct 140. When the adjustment plate 220 slides, the distance between it and the outer surface of the air guide block 210 facing the first side wall 110 will also change, that is, the width, flow area and flow rate of the first sub-air duct 140 will also change, thereby changing the flow rate of the merged airflow, that is, the outlet wind direction of the airflow.

[0072] like Figure 1 As shown, optionally, the indoor unit air outlet mechanism further includes a sweeping blade group 300 , the swing axis of the sweeping blade group 300 is parallel to or intersects with the width direction of the air duct 100 at an acute angle, and the sweeping blade group 300 is located in the second sub-air duct 150 .

[0073] The swing axis of the sweeping blade group 300 is parallel to or intersects the width direction of the air duct 100 at an acute angle, which means that the swing axis of the sweeping blade can be consistent with the width direction of the air duct 100, or form a small angle with the width direction. That is, when the sweeping blade swings, the airflow of the air outlet swings in the length direction of the air outlet 130. Specifically, Figure 1 In the illustrated embodiment, the swing axis of the sweep blade is located in the vertical plane. When the sweep blade swings, if the air conditioner indoor unit is a wall-mounted air conditioner indoor unit, the sweep blades in the sweep blade group 300 are left and right sweep blades.

[0074] Since the flow rate in the second sub-duct 150 is fixed compared to the first sub-duct 140, the adjustment plate 220 adjusts the flow area of ​​the first sub-duct 140. By setting the sweeping blade group 300 in the second sub-duct 150, the effect of the sweeping blade group 300 on changing the airflow direction is not affected by the adjustment of the air volume by the adjustment plate 220, thereby improving the sweeping effect of the sweeping blade group 300.

[0075] Of course, in another implementation, an adjustment plate 220 may be provided on both sides of the air guide block 210. Then, not only the sweeping blade group 300 but also the adjustment plate 220 may be provided in the second sub-air duct 150, so that the airflow volume of the first sub-air duct 140 and the second sub-air duct 150 can be adjusted, thereby making the airflow volume ratio on both sides of the air guide block 210 larger to change the final air outlet direction.

[0076] like Figure 1 As shown, optionally, the air guide block 210 is fixedly disposed in the air duct 100, and both the first side wall 110 and the second side wall 120 are arc-shaped and convex toward each other.

[0077] Specifically, in this embodiment, from the inlet to the outlet of the air duct 100, the maximum width of the air duct 100, that is, the width of the air duct 100 assuming that the air guide block 210 is not provided, first gradually increases and then gradually decreases. The adjustment plate 220 can be preferably arranged at a position where the maximum width of the air duct 100 is the largest or at a position adjacent thereto.

[0078] Taking the wall-mounted air conditioner indoor unit of this embodiment as an example, the first side wall 110 is the lower side wall of the air duct 100, and the second side wall 120 is the upper side wall of the air duct 100. Both the first side wall 110 and the second side wall 120 are arc-shaped and convex away from each other, which means that the first side wall 110 convexes downward, and the second side wall 120 convexes upward.

[0079] By arranging the first side wall 110 and the second side wall 120 to protrude away from the other, the protruding portions of the first side wall 110 and the second side wall 120 can be utilized to form a larger cross-sectional width to accommodate the air guide block 210, so that the arrangement of the air guide block 210 will not significantly reduce the overall ventilation area of ​​the airflow, thereby making the flow velocity and pressure of the outlet airflow in the air duct 100 more stable, reducing the flow resistance loss of the air duct 100, and improving the air outlet efficiency.

[0080] In this embodiment, the flow area of ​​the first sub-duct 140 is changed mainly by the movement of the adjustment plate 220. In fact, in another implementation, the air guide block 210 may be moved to change the ratio of the flow areas of the first sub-duct 140 and the second sub-duct 150. Specifically, when the air guide block 210 moves, the flow area of ​​one of the first sub-duct 140 and the second sub-duct 150 may be changed, or when the air guide block 210 moves, the flow areas of both the first sub-duct 140 and the second sub-duct 150 may be changed.

[0081] For example, the former can be specifically implemented by taking one end of the air guide block 210 in the width direction of the air duct 100 as the rotation center, and the rotation of the air guide block 210 changes the spacing between the other end in the width direction of the air duct 100 and the first side wall 110, thereby changing the flow area of ​​the first sub-air duct 140, while the flow area of ​​the second sub-air duct 150 remains unchanged. More specifically, the portion of the outer surface of the air guide block 210 facing the second side wall 120 is a portion of a cylindrical surface, and the axis of the cylindrical surface is the rotation center of the air guide block 210. When the air guide block 210 rotates, the position closest to the second side wall 120 is located within the range of the portion of the cylindrical surface, so the spacing from the second side wall 120 does not change. The local first side wall 110 corresponding to the air guide block 210 in the width direction of the air duct 100 can be a non-arc shape, or even if it is an arc surface, the center of the arc does not overlap with the rotation center of the air guide block 210. In this way, the swing of the air guide block 210 will cause the distance between it and the first side wall 110 to change, thereby driving the flow area of ​​the first sub-air duct 140 to change, and further causing the flow areas of the first sub-air duct 140 and the second sub-air duct 150 to change.

[0082] The latter can be specifically implemented in such a way that the position of the air guide block 210 outside the center or end along the width direction of the air duct 100 is the rotation center of the air guide block 210, that is, the air guide block 210 has one end larger than the other end relative to its rotation center. When the air guide block 210 rotates, the spacing between the two ends in the width direction of the air duct 100 and the corresponding first side wall 110 and second side wall 120 also changes, and the flow areas of the first sub-air duct 140 and the second sub-air duct 150 are changed, and the speed and proportion of the change are also different. Therefore, the flow area ratio of the first sub-air duct 140 and the second sub-air duct 150 is also changed, so that the final air outlet direction of the air duct 100 can be adjusted. In addition, the latter can also be specifically implemented in such a way that the air guide block 210 slides in the width direction of the air duct 100, or the sliding direction forms a small acute angle with the width direction of the wind, such as an acute angle of less than 30°, which can also achieve the same effect.

[0083] The operating principle of this embodiment is:

[0084] Taking the application of this embodiment to a wall-mounted air conditioner indoor unit as an example, when the angle of the adjustment plate 220 is changed, the flow area ratio of the first sub-duct 140 and the second sub-duct 150 is changed, that is, the flow area ratio of the sub-duct 100 above the air guide block 210 and the sub-duct 100 below the air guide block 210 is changed.

[0085] Figure 4 This is a schematic diagram of the structure of the indoor unit air outlet mechanism provided in the first embodiment of the utility model, in which the adjustment plate is retracted into the recessed portion in the first side wall; Figure 4 As shown, when the air outlet of the air conditioner is in the horizontal air outlet mode, that is, when the angle between the air outlet direction of the air conditioner and the vertical plane is large, the adjustment plate 220 is completely accommodated in the recessed portion 111 of the first side wall 110, and the first sub-duct 140 is in a state of maximum flow area, compared with when the adjustment plate 220 is at other angles, the air flow of the first sub-duct 140 is the largest. Therefore, after the airflows of the first sub-duct 140 and the second sub-duct 150 merge, the angle between the merged airflow and the vertical plane is the largest.

[0086] like Figure 1 As shown, when the air outlet of the air conditioner is in the transition mode, the non-pivoted end of the adjustment plate 220 in the width direction is located in the first sub-duct 140, and there is a gap between it and the air guide block 210. At this time, the airflow in the first sub-duct 140 is limited by the adjustment plate 220 and the air guide block 210, and its airflow is reduced. Therefore, after the airflow of the first sub-duct 140 and the airflow of the second sub-duct 150 flow through the air guide block 210, the airflow flow of the second sub-duct 150 is only increased compared with the airflow flow of the first sub-duct 140, so the overall airflow formed by the confluence is closer to the airflow direction of the second sub-duct 150, that is, compared with the horizontal air outlet mode, its angle with the vertical plane is reduced. The larger the rotation angle of the adjustment plate 220, the smaller the gap between it and the air guide block 210, the smaller the flow area of ​​the first sub-duct 140, and the lower the proportion of the airflow of the first sub-duct 140 in the confluent airflow, so that the final confluent airflow is more downward.

[0087] Figure 5 This is a schematic diagram of the structure of the indoor unit air outlet mechanism provided in the first embodiment of the utility model, in which the adjustment plate is in contact with the air guide block; Figure 5 As shown, when the air outlet of the air conditioner is in the vertical air outlet mode, that is, when the angle between the air outlet direction of the air conditioner and the vertical plane is small, the adjustment plate 220 contacts the air guide block 210, closing the first sub-duct 140, that is, the flow area of ​​the first sub-duct 140 is zero, then the flow area ratio of the first sub-duct 140 to the second sub-duct 150 is zero, and the airflow at the air outlet 130 of the air conditioner is consistent with the flow direction of the airflow of the second sub-duct 150, thereby achieving the maximum downward air outlet.
