Air conditioners can help people reach a temperature they can adapt to when the ambient temperature is too high or too low.

[0003] However, most users think that the current air conditioners blow too hard and too cold, and some users think that the air conditioners cool slowly, the wind is too weak, and not cool enough. In other words, the current air conditioners cannot fully meet the needs of users. In addition, the air supply problem of air conditioners has a great impact on people's daily lives, making users prone to air-conditioning diseases. Specifically, after the air conditioner blows directly or blows towards the user for a long time, the user is prone to colds, fevers, leg pain, joint pain and other symptoms, which seriously affects the user's physical health and user experience. Summary of the invention

[0004] One object of the present invention is to prevent the air from blowing directly onto the user and to effectively reduce the air supply resistance and noise.

[0005] A further object of the present invention is to match the air outlet of the indoor unit with the air outlet direction at the air duct outlet to increase the air supply volume.

[0024] This embodiment provides a wall-mounted air-conditioning indoor unit, which can change the air outlet direction without setting an air guide plate. It can not only avoid direct blowing of air and causing users to have various discomfort symptoms, but removing the air guide plate can also effectively reduce the air supply resistance, thereby reducing noise and improving the user experience. Figure 1 is a schematic diagram of a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 2 yes Figure 1 The schematic diagram of the wall-mounted air conditioner indoor unit 100 in another state is shown. Figure 3 yes Figure 1 The schematic diagram of the wall-mounted air conditioner indoor unit 100 in another state is shown. Figure 4 yes Figure 1 The wall-mounted air conditioner indoor unit 100 is shown in another state. Figures 1 to 4 As shown, the wall-mounted air-conditioning indoor unit 100 of this embodiment may generally include: a housing 110 , an evaporator 120 and a frame 130 .

[0025] The shell 110 defines a cavity inside to accommodate some related components. For example, the evaporator 120 can be disposed inside the cavity and configured to exchange heat with the air entering the cavity. The rear end of the skeleton 130 is connected to the rear end of the evaporator 120 and is configured to define an air duct 140 together with the evaporator 120. The air entering the cavity will flow along the air duct 140 after heat exchange through the evaporator 120. In a preferred embodiment, the longitudinal section of the skeleton 130 has two arcs protruding toward the rear panel 112 and the bottom plate 114. The air duct 140 defined by the skeleton 130 and the evaporator 120 of this shape is more suitable for air circulation and is conducive to air transportation.

[0026] It is important that the evaporator 120 and the frame 130 of this embodiment rotate together in a controlled manner so as to change the air outlet direction at the outlet 141 of the air duct 140. In other words, the evaporator 120 and the frame 130 rotate as a whole, thereby changing the air outlet direction at the outlet 141 of the air duct 140 defined together. The evaporator 120 and the frame 130 can rotate with the transverse central axis of the air duct 140 as a pivot axis.

[0027] In a specific embodiment, the housing 110 may include: a front panel 111 , a rear panel 112 , a top panel 113 , and a bottom panel 114 . Moreover, the front panel 111 is controlled to move upward to define an air outlet 115 together with the bottom panel 114 . Figure 1 The figure shows that the front panel 111 has not moved upwards, and the front panel 111 and the bottom plate 114 are completely closed. At this time, it can be considered that the air outlet 115 is in a closed state, and air cannot be supplied through the air outlet 115.

[0028] Figures 2 to 4 The front panel 111 moves up to different distances, and the evaporator 120 and the frame 130 rotate at different angles. However, it should be emphasized that the distance of the front panel 111 moving up matches the angle of rotation of the evaporator 120 and the frame 130, so that the wind blown out from the outlet 141 is sent out by the outlet 115.

[0029] In a preferred embodiment, there are three rotation angles of the evaporator 120 and the skeleton 130: a first angle α1, a second angle α2 and a third angle α3, wherein the first angle α1, the second angle α2 and the third angle α3 increase sequentially, and there are three corresponding distances for the front panel 111 to move upward: a first distance D1, a second distance D2 and a third distance D3, wherein the first distance D1, the second distance D2 and the third distance D3 increase sequentially.

[0030] It should be noted that the rotation angles of the evaporator 120 and the frame 130 may adopt different references. Figures 2 to 4The first angle α1, the second angle α2, and the third angle α3 shown are all angles formed between the front end of the evaporator 120 and the horizontal line. In some other embodiments, it can also be the angle formed between the rear end of the evaporator 120 and the horizontal line, the angle formed between the tangent of the arc of the skeleton 130 and the horizontal line, etc. But in general, the first angle α1, the second angle α2, and the third angle α3 can reflect the rotation of the evaporator 120 and the skeleton 130. The first distance D1, the second distance D2, and the third distance D3 reflect the size of the air outlet 115. The larger the distance, the larger the air outlet 115.

[0031] Figure 2 The evaporator 120 and the frame 130 rotate at a first angle α1, and the front panel 111 moves upwards by a first distance D1. In addition, when the wall-mounted air conditioner indoor unit 100 is in heating mode, the evaporator 120 and the frame 130 rotate at a first angle α1, and the front panel 111 moves upwards by a first distance D1, because at this time the outlet 141 and the air outlet 115 realize downward air discharge, and the air discharge can more easily reach the ground, forming a floor heating airflow.

[0032] Figure 3 The evaporator 120 and the frame 130 rotate at the second angle α2, and the front panel 111 moves upwards by the second distance D2. Regardless of whether the wall-mounted air conditioner indoor unit 100 is in cooling mode or heating mode, the evaporator 120 and the frame 130 rotate at the second angle α2, and the front panel 111 moves upwards by the second distance D2, because at this time the outlet 141 and the air outlet 115 achieve horizontal air discharge, which is suitable for either cold air or warm air.

[0033] Figure 4 The evaporator 120 and the frame 130 are rotated at a third angle α3, and the front panel 111 moves upwards by a third distance D3. In addition, when the wall-mounted air conditioner indoor unit 100 is in cooling mode, the evaporator 120 and the frame 130 can be rotated at a third angle α3, and the front panel 111 can move upwards by a third distance D3, because at this time the outlet 141 and the air outlet 115 can achieve upward air discharge, forming a canopy-style airflow, thereby preventing cold wind from blowing directly on the user and causing discomfort to the user.

[0034] In some other embodiments, the number of angles at which the evaporator 120 and the frame 130 rotate can be set to other values, and the number of distances that the front panel 111 moves upward can also be set to other corresponding values. For example, the angles at which the evaporator 120 and the frame 130 rotate can be increased by 2 on the basis of the above 3, and the distance that the front panel 111 moves upward can also be increased by 2 on the basis of the above 3. The first angle increased can be between the first angle α1 and the second angle α2, and the first distance increased can be between the first distance D1 and the second distance D2, so as to achieve the middle and lower air outlet of the outlet 141 and the air outlet 115. The second angle increased can be between the second angle α2 and the third angle α3, and the second distance increased can be between the second distance D2 and the third distance D3, so as to achieve the middle and upper air outlet of the outlet 141 and the air outlet 115.

[0035] It should also be noted that an air inlet 116 is provided on the top plate 113 so that air outside the wall-mounted air conditioner indoor unit 100 can enter the cavity. The wall-mounted air conditioner indoor unit 100 also includes: a fan 150, which is provided in the air duct 140 to blow the air that has undergone heat exchange in the evaporator 120 toward the outlet 141 and send it out from the air outlet 115. In a specific embodiment, the fan 150 can be a cross-flow fan, and the rotating shaft of the cross-flow fan extends in the lateral direction of the wall-mounted air conditioner indoor unit 100, and the extension length can be the same as the extension length of the air outlet 115, so as to ensure that the entire area of ​​the air outlet 115 can discharge air.

[0036] The wall-mounted air conditioner indoor unit 100 of this embodiment includes: a housing 110, which defines a cavity inside; an evaporator 120, which is disposed inside the cavity and configured to exchange heat with air entering the cavity; a frame 130, whose rear end is connected to the rear end of the evaporator 120, and configured to define an air outlet 140 together with the evaporator 120, and the evaporator 120 and the frame 130 are controlled to rotate together to change the air outlet direction at the outlet 141 of the air duct 140. No air guide plate is provided, but the evaporator 120 and the frame 130 are controlled to rotate together to change the air outlet direction at the outlet 141 of the air duct 140, which can not only avoid direct blowing of air to cause a variety of discomfort symptoms to the user, but also remove the air guide plate to effectively reduce the air supply resistance, thereby reducing noise and improving the user experience.

[0037] Further, in the wall-mounted air conditioner indoor unit 100 of this embodiment, the housing 110 includes: a front panel 111, a rear panel 112, a top panel 113 and a bottom panel 114, and the front panel 111 is controlled to move upward to define an air outlet 115 together with the bottom panel 114. The distance that the front panel 111 moves upward matches the angle of rotation of the evaporator 120 and the frame 130, so that the wind blown out from the outlet 141 is sent out from the air outlet 115. Specifically, in the heating mode, the evaporator 120 and the frame 130 rotate at a first angle α1, the front panel 111 moves upward by a first distance D1, the outlet 141 and the air outlet 115 realize downward air discharge, and the air discharge reaches the ground more easily, forming a floor heating airflow; in the cooling mode, the evaporator 120 and the frame 130 rotate at a third angle α3, the front panel 111 moves upward by a third distance D3, the outlet 141 and the air outlet 115 realize upward air discharge, forming a canopy airflow, and the air supply direction matches the actual needs of the user, effectively improving the air supply comfort. In addition, matching the air outlet 115 of the indoor unit 100 with the air outlet direction at the outlet 141 of the air duct 140 can ensure that the air blown out by the outlet 141 can be completely delivered through the air outlet 115, greatly improving the air supply volume.
