[0026] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0027] like Figures 1 to 3 As shown, the air conditioner indoor unit 100 of the embodiment of the present disclosure includes a housing 1 and an air guide plate 2. The lower portion of the housing 1 is provided with an air inlet 11. The housing 1 includes a front panel 13. The housing 1 is provided with an air outlet 12 on the upper side of the front panel 13. The air guide plate 2 is movably arranged at the air outlet 12. The front panel 13 is arranged to gradually tilt backward from top to bottom. When the air conditioner indoor unit 100 is in heating mode, the angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is 60° to 290°, and / or the angle between the front surface of the air guide plate 2 and the horizontal plane is 50° to 90°.

[0028] The front surface of the front panel 13 can be understood as the front surface of the front panel 13. The front surface of the air guide plate 2 can be understood as the front surface of the air guide plate 2 when the air guide plate 2 closes the air outlet 12.

[0029] The air conditioning indoor unit 100 of the disclosed embodiment is arranged such that the front panel 13 is gradually tilted backward from top to bottom, and the air outlet 12 is disposed on the upper side of the front panel 13. This allows the airflow flowing out of the air outlet 12 to enter the interior of the housing 1 from the lower side of the air outlet 12 through the air inlet 11, thereby increasing the temperature of the airflow entering the air inlet 11 and improving the heating effect of the air conditioning indoor unit 100. In addition, when the air conditioning indoor unit 100 is in the heating mode, the angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is set to 60° to 290°. This allows the airflow flowing out of the air outlet 12 to reach the ground at a higher speed after passing through the air guide plate 2 when the air conditioning indoor unit 100 is in the heating mode, thereby improving the heating effect of the air conditioning indoor unit 100. In addition, the angle between the front surface of the air guide plate 2 and the horizontal plane is set to 50°~90°, which will also make the air flow flowing out of the air outlet 12 have a higher landing speed after passing through the air guide plate 2 when the air conditioner indoor unit 100 is in heating mode, thereby improving the heating effect of the air conditioner indoor unit 100.

[0030] like Figures 1 to 3 As shown, the air conditioner indoor unit 100 further includes a fan 4 and a heat exchanger 5, both of which are disposed inside the housing 1. When the air conditioner indoor unit 100 is in operation, air, driven by the fan 4, enters the interior of the housing 1 through the air inlet 11, flows through the heat exchanger 5, exchanges heat with the heat exchanger 5, and then flows out through the air outlet 12.

[0031] The front panel 13 is arranged to be gradually tilted backward from top to bottom, so that when the air-conditioning indoor unit 100 is in heating mode, the air flow flowing out of the air outlet 12 can enter the interior of the shell 1 through the air inlet 11 from the lower side of the air outlet 12, thereby making the temperature of the air flow entering the air inlet 11 higher, and high-temperature sterilization of the heat exchanger 5 can also be achieved.

[0032] Optionally, the housing 1 further includes side panels disposed on the left and right sides of the front panel 13, and the front panel 13 is fixedly connected to the side panels. The angle between the front panel 13 and the vertical plane is 6° to 15°. In this case, the tilt angle of the front panel 13 is not adjustable.

[0033] The front panel 13 and the side panels may be welded, clamped or connected via fasteners, which may be bolts, screws, rivets, etc.

[0034] For example, Figure 3 As shown, the angle between the front panel 13 and the vertical plane is e1, and e1 is 6° to 15°.

[0035] It can be understood that the greater the inclination angle of the front panel 13, the more hot air enters through the air inlet 11, and the better the high-temperature sterilization effect of the heat exchanger 5, but the less hot air in the room, which is not conducive to improving the heating effect of the air conditioner indoor unit 100; and the smaller the inclination angle of the front panel 13, the less hot air enters through the air inlet 11, and the more hot air in the room, which is conducive to improving the heating effect of the air conditioner indoor unit 100, but the worse the high-temperature sterilization effect of the heat exchanger 5.

[0036] When the inclination angle of the front panel 13 is not adjustable, the inclination angle of the front panel 13 is set to 6°-15°, which can ensure the high-temperature sterilization effect of the heat exchanger 5 without affecting the indoor heating effect.

[0037] Optionally, when the air conditioner indoor unit 100 is in the heating mode, the included angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is 100°-290°, and / or the included angle between the front surface of the air guide plate 2 and the horizontal plane is 95°-125°.

[0038] For example, as shown in FIG. 1, when the air conditioner indoor unit 100 is in the heating mode, the included angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is a1, and a1 is 100°-290°. The included angle between the front surface of the air guide plate 2 and the horizontal plane is b1, and b1 is 55°-85°. Figure 1 When the inclination angle of the front panel 13 is not adjustable, the included angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is set to 100°-290°, so that when the air conditioner indoor unit 100 is in the heating mode, the landing speed of the air flow after the air flow from the air outlet 12 passes through the air guide plate 2 is large, thereby improving the heating effect of the air conditioner indoor unit 100. In addition, the included angle between the front surface of the air guide plate 2 and the horizontal plane is set to 55°-85°, which also makes the landing speed of the air flow after the air flow from the air outlet 12 passes through the air guide plate 2 large when the air conditioner indoor unit 100 is in the heating mode, thereby improving the heating effect of the air conditioner indoor unit 100.

[0039] Optionally, when the air conditioner indoor unit 100 is in the cooling mode, the included angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is 60°-270°, and / or the included angle between the front surface of the air guide plate 2 and the horizontal plane is 0°-20°.

[0040] For example, as shown in FIG. 2, when the air conditioner indoor unit 100 is in the cooling mode, the included angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is c1, and c1 is 60°-270°. The included angle between the front surface of the air guide plate 2 and the horizontal plane is d1, and d1 is 0°-20°.

[0041] Figure 2

[0042] ​​The inclination angle of the front panel 13 is not adjustable, and when the air conditioner indoor unit 100 is in the cooling mode, the included angle between the front surface of the air deflector 2 and the front surface of the front panel 13 is 60°-270°, so that when the air conditioner indoor unit 100 is in the cooling mode, the vortex formed by the airflow at the air deflector 2 can be reduced, thereby reducing the risk of condensation problem of the air conditioner indoor unit 100. In addition, the included angle between the front surface of the air deflector 2 and the horizontal plane is 0°-20°, which also reduces the vortex formed by the airflow at the air deflector 2 when the air conditioner indoor unit 100 is in the cooling mode, thereby reducing the risk of condensation problem of the air conditioner indoor unit 100.

[0043] As shown in Figures 1 to 3 The air conditioner indoor unit 100 further comprises an air outlet air duct 3 arranged in the interior of the shell 1. The air outlet air duct 3 comprises an arc-shaped section 31 and a straight section 32 arranged at the front side of the arc-shaped section 31, and the air outlet 12 is arranged at the front side of the straight section 32. The dimension of the straight section 32 in the front-rear direction is 62mm-88mm.

[0044] The arc-shaped section 31 can change the flow direction of the airflow while reducing the airflow resistance, and the straight section 32 can better guide the flow direction of the airflow, so that the airflow flows out of the air outlet 12 along the preset direction.

[0045] For example, as shown in Figure 1 The straight section 32 is arranged to be gradually inclined upward along the direction from front to back. The dimension of the straight section 32 in the front-rear direction is L1, and L1 is 62mm-88mm.

[0046] When the inclination angle of the front panel 13 is not adjustable, the dimension of the straight section 32 in the front-rear direction is set to be 62mm-88mm. In the case that the length of the straight section 32 is small, the straight section 32 can better guide the flow direction of the airflow, so that the airflow flows out of the air outlet 12 along the preset direction, thereby improving the air outlet effect of the air conditioner indoor unit 100.

[0047] Optionally, the inclination angle of the front panel 13 is not adjustable, and when the air conditioner indoor unit 100 is in the heating mode, the included angle between the front surface of the air deflector 2 and the front surface of the front panel 13 is 60°-290°, and / or the included angle between the front surface of the air deflector 2 and the horizontal plane is 50°-90°.

[0048] For example, as shown in Figure 1 The included angle between the front surface of the air deflector 2 and the front surface of the front panel 13 is a2, and a2 is 60°-290°. The included angle between the front surface of the air deflector 2 and the horizontal plane is b2, and b2 is 50°-90°.

[0049] As shown in Figures 1 to 3As shown, the front panel 13 is swingably connected to the side panels to adjust the tilt angle of the front panel 13 , and the angle between the front panel 13 and the vertical plane is 0° to 30°.

[0050] For example, the air conditioner indoor unit 100 includes a middle frame driving mechanism, the lower portion of the front panel 13 is hinged to the middle frame, the driving mechanism is mounted on the middle frame, and the driving mechanism is in transmission connection with the front panel 13. The driving mechanism drives the front panel 13 to swing, thereby adjusting the tilt angle of the front panel 13. The driving mechanism may include a motor and a swing arm, the motor drives the swing arm to swing, and the swing arm drives the front panel 13 to swing.

[0051] By setting the front panel 13 to have an adjustable tilt angle, it is convenient for the user to adjust the tilt angle of the front panel 13 as needed, thereby better meeting the user's needs.

[0052] Optionally, when the air-conditioning indoor unit 100 is in cooling mode, the angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is 70° to 280°, and / or the angle between the front surface of the air guide plate 2 and the horizontal plane is 8° to 30°.

[0053] For example, Figure 2 As shown, the angle between the front surface of the air deflector 2 and the front surface of the front panel 13 is c2, c2 is 70° to 280°, and the angle between the front surface of the air deflector 2 and the horizontal plane is d2, d2 is 8° to 30°.

[0054] When the inclination angle of the front panel 13 is adjustable, when the air conditioner indoor unit 100 is in cooling mode, the angle between the front surface of the air guide plate 2 and the front surface of the front panel 13 is set to 70° to 280°. This reduces eddies formed by the airflow at the air guide plate 2 when the air conditioner indoor unit 100 is in cooling mode, thereby reducing the risk of condensation in the air conditioner indoor unit 100. Furthermore, when the angle between the front surface of the air guide plate 2 and the horizontal plane is set to 8° to 30°, this also reduces eddies formed by the airflow at the air guide plate 2 when the air conditioner indoor unit 100 is in cooling mode, thereby reducing the risk of condensation in the air conditioner indoor unit 100.

[0055] Optionally, when the inclination angle of the front panel 13 is adjustable, the dimension of the straight section 32 in the front-to-back direction is 126 mm to 185 mm.

[0056] It is understandable that when the inclination angle of the front panel 13 is adjustable, the size of the air outlet duct 3 in the front-to-back direction also needs to be adaptively adjusted according to the inclination angle of the front panel 13 .

[0057] For example, Figure 1 As shown, the straight section 32 is arranged to gradually tilt upward from the front to the back. The dimension of the straight section 32 in the front-to-back direction is L2, and L2 is 126 mm to 185 mm.

[0058] When the inclination angle of the front panel 13 is adjustable, the size of the flat section 32 in the front-rear direction is 126mm-185mm, so that the front panel 13 can play a good guiding role on the flow direction of the air flow at different inclination angles, and the air outlet effect of the air conditioner indoor unit 100 is improved.

[0059] In some embodiments, the width of the air deflector 2 is 88mm-124mm.

[0060] For example, as shown in Figure 3 The width of the air deflector 2 is L3, and L3 is 88mm-124mm.

[0061] By setting the width of the air deflector 2 to 88mm-124mm, the air deflector 2 can effectively close the air outlet 12 when the front panel 13 is at different inclination angles, and the air outlet effect of the air conditioner indoor unit 100 in different working modes is good.
