[0024] For the indoor unit in the embodiment of the present application, when it is in use, the installation side facing the wall is the rear side, the side opposite to the rear side is the front side, the upper side of the indoor unit is the upper side, and the lower side of the indoor unit is the lower side.

[0025] See also Figures 1 to 4 As shown, according to an embodiment of the present application, the indoor unit includes a main frame 1, the main frame 1 includes an air outlet 2, and a motion panel 3 can be movably provided on the front side of the main frame 1. When the indoor unit is in a working state, along the line of sight from the motion panel 3 to the air outlet 2, the motion panel 3 completely blocks the air outlet 2.

[0026] When the indoor unit is in working state, the air outlet 2 is in an open state, and the moving panel can completely block the air outlet 2 in the sight direction. Therefore, even if the indoor unit is in working state, it can still be ensured that the user's sight of the air outlet 2 can be blocked by the moving panel 3 when the air conditioner is normally used, so that the air conditioning structure viewed by the user is still the air conditioning appearance structure, and the air outlet 2 is hidden in the working state, ensuring the appearance consistency of the air conditioner. The air outlet 2 in this embodiment is, for example, a lower air outlet.

[0027] The main frame 1 includes a bottom shell and a panel body, the air outlet 2 can be arranged on the bottom shell or the panel body, and the motion panel 3 can be installed on the bottom shell or the panel body.

[0028] The present application takes a wall-mounted unit as an example. Generally, when the user is using the indoor unit, he or she is located in front of the indoor unit. Therefore, considering the installation height of the indoor unit and the user's body height, generally, when the user's line of sight looks toward the lower edge of the air outlet 2 close to the installation side, the angle between the line of sight and the horizontal plane will not be greater than 60°. Therefore, as long as it can be ensured that when the user's line of sight looks toward the lower edge of the motion panel 3, the angle θ between the line of sight direction and the horizontal plane satisfies 0°≤θ≤60°, it can be ensured that when the indoor unit is working, the motion panel 3 can completely block the air outlet 2, so that the user cannot see the air outlet 2, but can see the exterior structural parts of the air conditioner, thereby obtaining a better visual experience.

[0029] In one embodiment, 0°≤θ≤45°. From a more precise perspective, the aesthetic considerations for the appearance of the air conditioner are mostly focused on the cost. Therefore, in combination with the body height of an adult user, the angle θ between the line of sight and the horizontal plane is limited to 0°≤θ≤45°, which can meet the requirement of shielding the air outlet 2 when the indoor unit is in working state. At the same time, it can also avoid that the angle θ is too large, resulting in the length of the motion panel 3 being too long and causing obstruction to the air outlet 2, affecting the air outlet effect.

[0030] In one embodiment, when the indoor unit is in the off state, the motion panel 3 is in the covered state, and the motion panel 3 covers at least part of the air outlet 2, thereby reducing the exposed area of ​​the air outlet 2 and enhancing the appearance consistency of the indoor unit, so that the user can obtain a good visual experience when the indoor unit is in the off state.

[0031] In one embodiment, when the indoor unit is in the off state, the motion panel 3 covers all the air outlets 2, which can ensure that when the indoor unit is in the off state, the air outlets 2 are completely blocked by the motion panel 3, so that the air outlets 2 are not exposed, making the overall appearance of the indoor unit more consistent and better looking.

[0032] In one embodiment, the moving panel can avoid the air outlet 2 so as not to affect the normal air outlet of the indoor unit.

[0033] In one embodiment, the motion panel 3 can be rotatably mounted on the main frame 1, and the rotation center of the motion panel 3 is located on the side of the motion panel 3 away from the air outlet 2, and the motion panel 3 rotates and opens in the direction away from the air outlet 2. In this embodiment, the motion panel 3 can be rotatably mounted on the main frame 1 through the panel shaft 9. Since the rotation center of the motion panel 3 is located on the side of the motion panel 3 away from the air outlet 2, when the air outlet 2 is a downward air outlet, the rotation center of the motion panel 3 is located on the upper side of the main frame 1, which can make the rotation center of the motion panel 3 as far away from the upper side of the air outlet 2 as possible, so that even if the motion panel 3 rotates a small angle, it can produce a larger movement distance at the lower edge of the motion panel 3, expand the adjustment range of the motion panel 3, and enable the position of the motion panel 3 to better block the line of sight of the air outlet 2, so as to obtain a better visual effect. The panel shaft 9 can be driven to rotate by a motor or a motion mechanism. The motion mechanism is, for example, a gear rack structure, or other drive mechanisms.

[0034] In one embodiment, the motion panel 3 is presented as an integral structure and completely covers the front side of the main frame 1, so that in the user's visual direction, the indoor unit can be presented as an integral structure to obtain a better appearance experience.

[0035] In one embodiment, a first air guide plate 4 is provided at the air outlet 2, and the first air guide plate 4 closes the air outlet 2 when the indoor unit is in the off state, and opens the air outlet 2 when the indoor unit is in the working state. When the indoor unit is in the off state, the first air guide plate 4 is covered at the air outlet 2, and the motion panel 3 is covered at the first air guide plate 4, covering the first air guide plate 4 and the air outlet 2 at the same time, forming a better appearance.

[0036] The first air guide plate 4 is rotatably connected to the edge of one side of the air outlet 2 near the moving panel 3. The first air guide plate 4 can be driven to rotate by a motor or a transmission mechanism, and can guide the air outlet of the air outlet 2. At the same time, when the air outlet 2 is discharged, the air duct can be isolated from the cavity between the moving panel 3 and the main frame 1, so as to avoid the problem that the airflow of the air outlet 2 is blown into the cavity to generate a vortex eddy current, thereby increasing the airflow resistance of the air outlet and reducing the wind speed.

[0037] In one embodiment, when the indoor unit is in operation, the edge of the moving panel 3 close to the air outlet 2 is located outside the extension line of the first air guide plate 4. In this embodiment, since the moving panel 3 is located outside the extension line of the first air guide plate 4 when the air outlet 2 is in the air outlet state, the guiding effect of the first air guide plate 4 on the air outlet can be utilized, so that the air outlet of the air outlet 2 does not flow like the moving panel 3, so that the air outlet airflow of the air outlet 2 can be effectively prevented from entering the above-mentioned cavity, thereby avoiding the generation of vortex eddies, which leads to increased airflow resistance at the air outlet and reduced wind speed.

[0038] In one embodiment, the edge of the moving panel 3 close to the air outlet 2 is connected to the edge of the first air guide plate 4 away from the air outlet 2, and a barrier can be formed through the direct contact between the first air guide plate 4 and the moving panel 3, thereby preventing the air flow from the air outlet 2 from entering the cavity through the gap between the first air guide plate 4 and the moving panel 3.

[0039] In one embodiment, a first air guide plate 4 and a second air guide plate 5 are provided at the air outlet 2. The first air guide plate 4 can be rotatably connected to the side edge of the air outlet 2 close to the moving panel 3, and the second air guide plate 5 can be rotatably connected to the side edge of the air outlet 2 away from the moving panel 3. When the indoor unit is in the off state, the first air guide plate 4 and the second air guide plate 5 cooperate to close the air outlet 2. When the indoor unit is in the working state, the first air guide plate 4 and the second air guide plate 5 cooperate to open the air outlet 2.

[0040] In this embodiment, when the indoor unit is in the off state, the first air guide plate 4 and the second air guide plate 5 are cooperatively covered at the air outlet 2, and the motion panel 3 is covered on the outside of the first air guide plate 4 and the second air guide plate 5, and at the same time covers the first air guide plate 4, the second air guide plate 5 and the air outlet 2, forming a better appearance.

[0041] When the indoor unit is in operation, the first air guide plate 4 and the second air guide plate 5 are simultaneously in the state of opening the air outlet 2, which can guide and reverse the airflow blown out of the air outlet 2, thereby making the air supply range of the air conditioner larger and the comfort better.

[0042] In one embodiment, when the indoor unit is in operation, the edge of the moving panel 3 close to the air outlet 2 is located outside the extension line of the first air guide plate 4. In this embodiment, since the moving panel 3 is located outside the extension line of the first air guide plate 4 when the air outlet 2 is in the air outlet state, the guiding effect of the first air guide plate 4 on the air outlet can be utilized, so that the air outlet of the air outlet 2 does not flow like the moving panel 3, so that the air outlet airflow of the air outlet 2 can be effectively prevented from entering the above-mentioned cavity, thereby avoiding the generation of vortex eddies, which leads to increased airflow resistance at the air outlet and reduced wind speed.

[0043] In one embodiment, when the indoor unit is in working state, the edge of the moving panel 3 close to the air outlet 2 is connected with the edge of the first air guide plate 4 away from the air outlet 2, and a barrier can be formed through the direct contact between the first air guide plate 4 and the moving panel 3, thereby preventing the air flow from the air outlet 2 from entering the cavity through the gap between the first air guide plate 4 and the moving panel 3.

[0044] The indoor unit further includes an air inlet 6, a fan 7 and a heat exchanger 8. The heat exchanger 8 is located between the air inlet 6 and the fan 7. The fan 7 is, for example, a cross-flow fan.

[0045] For the indoor unit of the present embodiment, when the air conditioner is in the off state, the moving panel 3 and the air guide plate are closed to cover the air outlet 2. At this time, the air outlet 2 is completely wrapped by the moving panel 3 and is in a fully closed state. When the air conditioner is turned on, the moving panel 3 and the air guide plate are rotated to open. At this time, when the air conditioner is observed from the lower front side or the lower side, the line of sight to the air outlet 2 is blocked by the lower edge of the moving panel 3, so that the air outlet 2 cannot be seen under normal use, thereby realizing the hiding of the air outlet 2.

[0046] According to an embodiment of the present application, the air conditioner includes an indoor unit, which is the indoor unit mentioned above.

[0047] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
