At the same time, hot air is easy to form vortex in the gap, producing noise, etc. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problem that there is a large gap between large-area air guide panel and front panel, leading to the escape of part of hot air from the gap, which affects the use comfort of user.

[0006] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: when the first air guide plate is in the first air guide position and the second air guide plate is in the first opening position, the air outlet direction of the indoor unit is downward, and the indoor unit is in heating mode; when the indoor unit is in heating mode, the first edge abuts against the front panel, avoiding a large gap between the first edge and the front panel when blowing hot air, and an air outlet spacing is formed between the second edge and the panel body, so that the indoor unit can blow the air blown out of the air outlet to indoor space when heating; the utility model can avoid the escape of hot air from the gap between the upper edge (i.e. the first edge) of the second air guide plate and the front panel when blowing hot air from the indoor unit, thereby improving the use comfort of user.

[0007] In one embodiment of this utility model, the second edge and the lower edge of the air outlet have a first horizontal distance in the horizontal direction. The first air guide plate also has a first closed position, with a first reference surface parallel to the first air guide plate in the first closed position, and an angle M formed between the air guiding direction of the first air guide plate and the first reference surface; when the indoor unit is in heating mode, the first air guide plate is in the first air guiding position, with a first horizontal spacing It gradually increases as the included angle M increases.

[0008] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: the horizontal distance between the second edge of the second guide plate and the lower edge of the air outlet is the first horizontal spacing. Alternatively, it can be said that there is a gap between the second edge and the bottom shell, and the width of the gap is... When the air outlet is closed, the first air guide plate remains in the first closed position. The airflow direction of the first air guide plate at this time is defined as the first reference surface, and the first airflow angle of the first air guide plate is the included angle M formed between the airflow direction of the first air guide plate and the first reference surface. When the indoor unit is in heating mode, as the included angle M increases, the first air guide plate rotates around the first gear towards the side away from the air outlet. The first air guide plate drives the second air guide plate to rotate towards the direction away from the air outlet. During this process, the first horizontal spacing... The distance gradually increases, with the first edge of the second air guide plate always abutting against the front panel. Similarly, when the indoor unit is in heating mode, the first horizontal distance... It gradually decreases as the included angle M decreases.

[0009] In one embodiment of this utility model, the line connecting the first edge and the second edge forms a second reference surface; the air guiding direction of the first air guide plate forms an angle N between the second reference surface; when the indoor unit is in heating mode, the angle N gradually increases as the angle M increases.

[0010] Compared with existing technologies, the technical effects achieved by this solution are as follows: The line connecting the first and second edges of the second air guide plate forms a second reference surface. This second reference surface is not fixed; it changes as the second air guide plate rotates. The airflow direction of the first air guide plate forms an angle N with the second reference surface. Angle N changes with angle M, and when the indoor unit is in heating mode, angle N gradually increases as angle M increases.

[0011] In one embodiment of this utility model, when the indoor unit is in heating mode, .

[0012] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: The first air guiding position is not a specific location, but rather includes multiple specific locations within the first air guiding range, which is: .

[0013] In one embodiment of this utility model, the first air guide plate also has a second air guide position for opening the air outlet, and the second air guide plate also has a second open position for guiding the air and a second closed position for closing the air outlet; wherein, when the indoor unit is in cooling mode, when the first air guide plate is in the second air guide position, the second air guide plate is in the second open position.

[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the first air guide plate is in the second air guide position and the second air guide plate is in the second open position, the air outlet direction of the indoor unit is upward, and the indoor unit is in cooling mode. The switching of the indoor unit's air outlet direction is achieved through the positions of the first and second air guide plates. Especially when the indoor unit is in cooling mode, a first horizontal gap still exists between the second edge and the lower edge of the air outlet. The second air guide plate and the front panel form the first air outlet channel, and the second air guide plate and the panel body form the second air outlet channel. This allows the airflow to blow along the outer surface of the second air guide plate, effectively extending the length of the air duct when the air is vented upwards, increasing the air delivery distance, avoiding the problem of cold air blowing directly on people, and improving the user experience.

[0015] In one embodiment of this utility model, when the indoor unit is in cooling mode, the included angle M remains unchanged, and the first horizontal distance... It gradually decreases as the included angle N increases.

[0016] Compared with existing technologies, the technical effect achieved by adopting this technical solution is: setting a first horizontal spacing. This is used to increase thermal interaction and prevent cold air from blowing directly on people, achieving a more uniform temperature distribution and increased comfort in the indoor space. First horizontal spacing It is not a fixed value; the first horizontal spacing changes as the second air guide plate rotates. There are changes; when the indoor unit is in cooling mode, generally, the included angle M ≤ 90°. With the included angle M remaining constant, the first horizontal spacing... The distance gradually decreases as the included angle N increases. Similarly, when the indoor unit is in cooling mode and the included angle M remains constant, the first horizontal distance... It gradually increases as the included angle N decreases.

[0017] In one embodiment of this utility model, when the indoor unit is in cooling mode, .

[0018] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the second opening position is not a specific location, but rather a specific location included within the second opening range, which is: .

[0019] In one embodiment of this utility model, the first edge and the outer edge of the front panel have a second horizontal distance in the horizontal direction. When the first air guide plate is in the first air guide position, .

[0020] Compared with existing technologies, the technical effect achieved by this solution is as follows: When the indoor unit is in heating mode, the first edge of the second air guide plate abuts against the front panel. If there were no gap between the second air guide plate and the front panel, long-term contact could cause wear on the front panel. Therefore, a gap is provided between the second air guide plate and the front panel, the gap being the second horizontal distance. And the second horizontal spacing Smaller to reduce the amount of hot air escaping from the gap. Preferably, .

[0021] In one embodiment of this utility model, a first horizontal plane is provided below the indoor unit, and a second horizontal plane is provided above the indoor unit; at a first moment, the horizontal distance from which the air blown out of the air outlet reaches the first horizontal plane is the first contact distance. The horizontal distance from which the air blown out of the vent reaches the second horizontal plane is the second contact distance. At time T, the horizontal distance from which the air blown out of the vent reaches the first horizontal plane is the first maximum distance. The horizontal distance from which the air blown out of the vent reaches the second horizontal plane is the second farthest distance. .

[0022] Compared with existing technologies, the technical effects achieved by this solution are as follows: The first moment is determined based on the indoor unit's response speed; the first moment can be represented as the moment when the indoor unit just begins to run; the first contact distance... This can also be expressed as the horizontal distance at which the air blown out by the indoor unit first lands on the first horizontal plane; time T is the time after the indoor unit has been running for time T. The air blown out at time T will push the airflow at time (T-1) away from the indoor unit, representing the first furthest distance. This can also be expressed as the furthest horizontal distance that the air blown by the indoor unit will reach the first horizontal plane after a time interval T. Preferably, the first horizontal plane is the ground. Second contact distance It can also be expressed as the horizontal distance from which the air blown out by the indoor unit first lands on the second horizontal plane; the second furthest distance. It can also be expressed as the furthest horizontal distance that the air blown out by the indoor unit will reach the second horizontal plane after a time period T. Preferably, the second horizontal plane is a horizontal plane 2m above the ground.

[0023] In one embodiment of this utility model, when the indoor unit is in heating mode, the first contact distance The farthest distance from the first The second contact distance gradually increases as the included angle M increases; when the indoor unit is in cooling mode, the second contact distance... Second farthest distance It gradually decreases as the included angle N increases.

[0024] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the indoor unit is in heating mode, the hot air is discharged downwards, meaning a large amount of hot air flows towards the first horizontal plane. As the included angle M increases, the first horizontal distance... Gradually increasing, and the first contact distance The farthest distance from the first It also gradually increases; when the indoor unit is in cooling mode, the direction of the cold air outlet is downward, that is, a large amount of cold air moves towards the direction of the second horizontal plane. As the included angle N increases, the first horizontal distance... Gradually decreasing, and the second contact distance Second farthest distance It also gradually decreased.

[0025] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0026] (1) While the indoor unit blows out hot air, the present invention can prevent hot air from escaping from the gap between the upper edge of the second air guide plate (that is, the first edge) and the front panel, thereby improving the user's comfort.

[0027] (2) When the indoor unit is in cooling mode, there is still a first horizontal gap between the second edge and the lower edge of the air outlet. The second air guide plate and the front panel form the first air outlet channel, and the second air guide plate and the panel body form the second air outlet channel. This allows the airflow to blow along the outer surface of the second air guide plate, effectively extending the air duct length when the air is vented upwards, increasing the air delivery distance, avoiding the problem of cold air blowing directly on people, and improving the user experience.

[0028] (3) An angle N is formed between the air guiding direction of the first air guide plate and the second reference surface. The angle N changes with the angle M. When the indoor unit is in heating mode, the angle N gradually increases with the increase of the angle M.

[0029] (4) When the indoor unit is in cooling mode, with the included angle M remaining unchanged, the first horizontal distance It gradually decreases as the included angle N increases. Attached Figure Description

[0044] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] Example 1

[0046] See Figure 1 This utility model provides an indoor unit, combined with Figures 2-12 The indoor unit includes a housing and an air guide plate assembly. The housing includes a bottom shell 10, a panel body 20, and a front panel 30. The front panel 30 and / or the panel body 20 are connected to the bottom shell 10, and the panel body 20 has an air outlet 21. The front panel 30 is connected to the panel body 20. The air guide plate assembly is connected to the housing and is movably installed at the air outlet 21. The air guide plate assembly includes a first air guide plate 410 and a second air guide plate 420. The second air guide plate 420 is connected to the first air guide plate 410, and the second air guide plate 420 has a first edge 421 and a second edge 422. The first air guide plate 410 has a first air guiding position that opens the air outlet 21, and the second air guide plate 420 has a first open position that guides the air. When the first air guide plate 410 is in the first air guiding position and the second air guide plate 420 is in the first open position, the first edge 421 abuts against the front panel 30, and an air outlet gap is formed between the second edge 422 and the panel body 20.

[0047] In one specific embodiment, the indoor unit has a housing and an air guide plate assembly. The air guide plate assembly is installed on the bottom shell 10 in the housing, and the panel body 20 and the front panel 30 in the housing can be set separately or as a whole. The air guide plate assembly includes a first air guide plate 410 and a second air guide plate 420. The first air guide plate 410 has a first closed position and a first air guiding position and a second air guiding position with the air outlet 21 open. The second air guide plate 420 has a second closed position with the air outlet 21 closed and a first open position and a second open position to guide the air. The first closed position does not indicate that the first air guide plate 410 can independently close the air outlet, but only indicates the closed state of the first air guide plate 410. The second closed position indicates that the second air guide plate 420 can independently close the air outlet. The second air guide plate 420 is positioned downstream of the first air guide plate 410 in the airflow. The second air guide plate 420 is rotatable relative to the first air guide plate 410, meaning the first air guide plate 410 can drive the second air guide plate 420 to rotate. The first air guide plate 410 is a small air guide plate, and there are multiple first air guide plates 410. The second air guide plate 420 is a large air guide plate, and there is only one second air guide plate 420. By adjusting the first air guide plate 410 to different air guiding positions, the opening position of the second air guide plate 420 can be changed, thereby changing the airflow direction of the air outlet 21. This ensures that the cold air is directed upwards during cooling and the hot air is directed downwards during heating, allowing cold air to descend from a high position and hot air to quickly reach the ground. The second air guide plate 420 includes a first edge 421 near the front panel 30 and a second edge 422 near the panel body 20. When the second air guide plate 420 is in the second closed position, the first edge 421 abuts against the upper edge of the air outlet 21, and the second edge 422 abuts against the lower edge of the air outlet 21.

[0048] Specifically, when the first air guide plate 410 is in the first air guide position and the second air guide plate 420 is in the first open position, the air outlet direction of the indoor unit is downward and the indoor unit is in heating mode; and the first edge 421 abuts against the front panel 30 to avoid a large gap between the first edge 421 and the front panel 30 when blowing hot air, and the second edge 422 forms an air outlet gap with the panel body 20, so that when the indoor unit is heating, the air blown out of the air outlet 21 can be blown into the indoor space through the air outlet gap; while the indoor unit blows out hot air, this utility model can prevent hot air from escaping from the gap between the upper edge of the second air guide plate 420 (that is, the first edge 421) and the front panel 30, thereby improving the user's comfort.

[0049] Furthermore, the second edge 422 and the lower edge of the air outlet 21 have a first horizontal distance in the horizontal direction; the first air guide plate 410 also has a first closed position, the first reference surface 1 is parallel to the first air guide plate 410 when it is in the first closed position, and the air guiding direction of the first air guide plate 410 and the first reference surface 1 form an angle M; when the indoor unit is in heating mode, the first air guide plate 410 is in the first air guiding position, and the first horizontal distance... It gradually increases as the included angle M increases.

[0050] Specifically, the horizontal distance between the second edge 422 of the second air guide plate 420 and the lower edge of the air outlet 21 is the first horizontal spacing. Alternatively, it can be said that there is a gap between the second edge 422 and the bottom shell 10, and the width of the gap is... When the air outlet 21 is closed, the first air guide plate 410 remains in the first closed position. The air guiding direction of the first air guide plate 410 at this time is defined as the first reference surface 1. The first air guiding angle of the first air guide plate 410 is the included angle M formed between the air guiding direction of the first air guide plate 410 and the first reference surface 1. When the indoor unit is in heating mode, generally, the included angle M ≥ 90°. As the included angle M increases, the first air guide plate 410 rotates around the first gear 411 towards the side away from the air outlet 21 (in the figure, the first air guide plate 410 rotates clockwise). The first air guide plate 410 drives the second air guide plate 420 to rotate away from the air outlet 21. During this process, the first horizontal spacing... The distance gradually increases, with the first edge 421 of the second air guide plate 420 always abutting against the front panel 30. Similarly, when the indoor unit is in heating mode, the first horizontal distance... It gradually decreases as the included angle M decreases.

[0051] Further, see Figure 2 The line connecting the first edge 421 and the second edge 422 forms the second reference surface 2; the air guiding direction of the first air guide plate 410 forms an angle N between the second reference surface 2; when the indoor unit is in heating mode, the angle N gradually increases as the angle M increases.

[0052] Specifically, the line connecting the first edge 421 and the second edge 422 of the second air guide plate 420 forms the second reference surface 2. The second reference surface 2 is not fixed; it changes as the second air guide plate 420 rotates. The air guiding direction of the first air guide plate 410 forms an angle N with the second reference surface 2. The angle N changes with the angle M, and when the indoor unit is in heating mode, the angle N gradually increases as the angle M increases.

[0053] Furthermore, when the indoor unit is in heating mode, .

[0054] Specifically, the optional first air guide position is not a specific location, but rather a set of multiple specific locations included within the first air guide range. The first air guide range is: See also Figures 5-9 The display shows the indoor unit status when the included angle M is 150°, 130°, 120°, 110° and 100°: when the included angle M is 150°, the included angle N is 58°; when the included angle M is 130°, the included angle N is 42°; when the included angle M is 120°, the included angle N is 35°; when the included angle M is 110°, the included angle N is 29°; when the included angle M is 100°, the included angle N is 24°.

[0055] Further, see Figure 3 The first air guide plate 410 also has a second air guide position for opening the air outlet 21, and the second air guide plate 420 also has a second open position for guiding the air and a second closed position for closing the air outlet 21; wherein, when the indoor unit is in cooling mode, when the first air guide plate 410 is in the second air guide position, the second air guide plate 420 is in the second open position.

[0056] Specifically, when the first air guide plate 410 is in the second air guide position and the second air guide plate 420 is in the second open position, the indoor unit's air outlet direction is upward, and the indoor unit is in cooling mode. The position of the first air guide plate 410 and the second air guide plate 420 achieves the switching of the indoor unit's air outlet direction. Especially when the indoor unit is in cooling mode, there is still a first horizontal gap between the second edge 422 and the lower edge of the air outlet 21. A first air outlet channel 211 is formed between the second air guide plate 420 and the front panel 30, and a second air outlet channel 212 is formed between the second air guide plate 420 and the panel body 20. This allows the airflow to blow along the outer surface of the second air guide plate 420, effectively extending the duct length when the air is outleted upward, increasing the air delivery distance, avoiding the problem of cold air blowing directly on people, and improving the user experience.

[0057] Further, see Figure 4 When the indoor unit is in cooling mode, the included angle M remains unchanged, and the first horizontal distance... It gradually decreases as the included angle N increases.

[0058] Specifically, the second edge 422 and the lower edge of the air outlet 21 have a first horizontal distance in the horizontal direction. In cooling mode, Set the first horizontal spacing This is used to increase thermal interaction and prevent cold air from blowing directly on people, achieving a more uniform temperature distribution and increased comfort in the indoor space. First horizontal spacing It is not a fixed value; as the second air guide plate 420 rotates, the first horizontal spacing... There are changes; when the indoor unit is in cooling mode, generally, the included angle M ≤ 90°. With the included angle M remaining constant, the first horizontal spacing... The distance gradually decreases as the included angle N increases. Similarly, when the indoor unit is in cooling mode and the included angle M remains constant, the first horizontal distance... It gradually increases as the included angle N decreases.

[0059] Furthermore, when the indoor unit is in cooling mode, .

[0060] Specifically, the optional second opening position is not a specific location, but rather a specific location included within the second opening range. The second opening range is: See also Figures 10-12 This displays the indoor unit status when the included angle M is 80° and the included angle N is 105°, 110°, and 115°: When the included angle N is 105°, When the included angle N is 110°, When the included angle N is 115°, .

[0061] Furthermore, the first edge 421 and the outer edge of the front panel 30 have a second horizontal distance in the horizontal direction. When the first air guide plate 410 is in the first air guide position, .

[0062] Specifically, when the indoor unit is in heating mode, the first edge 421 of the second air guide plate 420 abuts against the front panel 30. If there were no gap between the second air guide plate 420 and the front panel 30, long-term contact could cause wear on the front panel. Therefore, a gap is provided between the second air guide plate 420 and the front panel 30, the gap being the second horizontal distance. And the second horizontal spacing Smaller to reduce the amount of hot air escaping from the gap. Preferably, .

[0063] Furthermore, a first horizontal plane is provided below the indoor unit, and a second horizontal plane is provided above the indoor unit; at the first moment, the horizontal distance from which the air blown out of the air outlet 21 reaches the first horizontal plane is the first contact distance. The horizontal distance from which the air blown out of the air outlet 21 reaches the second horizontal plane is the second contact distance. At time T, the horizontal distance from which the wind blowing from vent 21 reaches the first horizontal plane is the first maximum distance. The horizontal distance from which the air blown out of vent 21 reaches the second horizontal plane is the second farthest distance. .

[0064] Specifically, the first moment is determined based on the indoor unit's response speed. The first moment can be represented as the moment when the indoor unit just starts running, and the first contact distance. This can also be expressed as the horizontal distance at which the air blown out by the indoor unit first lands on the first horizontal plane; time T is the time after the indoor unit has been running for time T. The air blown out at time T will push the airflow at time (T-1) away from the indoor unit, representing the first furthest distance. It can also be expressed as the furthest horizontal distance that the air blown out by the indoor unit will reach the first horizontal plane after a time period T. Preferably, the first horizontal plane is the ground.

[0065] Second contact distance It can also be expressed as the horizontal distance from which the air blown out by the indoor unit first lands on the second horizontal plane; the second furthest distance. It can also be expressed as the furthest horizontal distance that the air blown out by the indoor unit will reach the second horizontal plane after a time period T. Preferably, the second horizontal plane is a horizontal plane 2m above the ground.

[0066] Further, see Figure 2 and Figure 4 When the indoor unit is in heating mode, the first contact distance The farthest distance from the first The second contact distance gradually increases as the included angle M increases; when the indoor unit is in cooling mode, the second contact distance... Second farthest distance It gradually decreases as the included angle N increases.

[0067] Specifically, when the indoor unit is in heating mode, the hot air is directed downwards, meaning a large amount of hot air flows towards the first horizontal plane. As the angle M increases, the first horizontal distance... Gradually increasing, and the first contact distance The farthest distance from the first It also gradually increases; when the indoor unit is in cooling mode, the direction of the cold air outlet is downward, that is, a large amount of cold air moves towards the direction of the second horizontal plane. As the included angle N increases, the first horizontal distance... Gradually decreasing, and the second contact distance Second farthest distance It also gradually decreased.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
