"Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon; that is, a target object (e.g., evaporator) absorbs heat while refrigerating.

[0041] like Figures 1 to 3 As shown, in some embodiments of this utility model, the indoor unit 001 of the air conditioner includes a housing 110, a heat exchanger 120, a fan 130, a first horizontal air guide plate 200, a first motor 300, an optional second horizontal air guide plate 400, and an optional second motor 500.

[0042] like Figure 1 As shown, in some embodiments of this utility model, the housing 110 is configured to be mounted on a wall, that is, the indoor air conditioner unit 001 of this utility model can be a wall-mounted indoor air conditioner unit. The housing 110 is provided with an air inlet 111 and an air outlet duct 112 communicating with the air inlet 111. The air inlet 111 can be located on the top side of the housing 110, the air outlet duct 112 is formed inside the housing 110, and the air outlet 1121 of the air outlet duct 112 is located at the lower front part of the housing 110.

[0043] In addition, in other embodiments of this utility model, those skilled in the art can also, as needed, set the air inlet 111 at other locations on the housing 110, for example, set at least a portion of the air inlet 111 at the top of the front side of the housing 110.

[0044] Continue reading Figure 1 In some embodiments of this utility model, the heat exchanger 120 is installed inside the housing 110 and located between the air inlet 111 and the air outlet duct 112 to heat or cool the air flowing from the air inlet 111 to the air outlet duct 112.

[0045] Those skilled in the art will understand that the indoor unit 001 of an air conditioner is generally used in conjunction with the outdoor unit (not shown in the figure) to form a complete refrigerant circulation system. A complete refrigerant circulation system generally includes a compressor, condenser, electronic expansion valve and / or capillary tube, evaporator, etc.

[0046] As can be understood by those skilled in the art, when the air conditioner indoor unit 001 is cooling, the heat exchanger 120 is used as an evaporator to cool the air in the casing 110. When the air conditioner indoor unit 001 is heating, the heat exchanger 120 is used as a condenser to heat the air in the casing 110.

[0047] With continued reference to Figure 1 In some embodiments of the present application, the fan 130 can be a cross-flow fan, and is installed into the casing 110 to drive the air to flow from the air inlet 111 to the air outlet 112.

[0048] As shown in Figures 1 to 3 some embodiments of the present application, the first transverse air deflector 200 is rotatably installed on the casing 110 and is used to change the direction of the air flow blown out from the air outlet 1121. The first transverse air deflector 200 includes the outer air deflector 210 and the inner air deflector 220 which are arranged in a spaced manner, and the outer air deflector 210 is arranged in a V shape.

[0049] As can be understood by those skilled in the art, by arranging the first transverse air deflector 200 to include the outer air deflector 210 and the inner air deflector 220 which are arranged in a spaced manner, and arranging the outer air deflector 210 in a V shape, the first transverse air deflector 200 of the present application can divide the air flow into three streams when guiding the air flow, can converge and / or change the direction of the air flow flowing along the inner side of the outer air deflector 210, and can disperse the air flow flowing along the outer side of the outer air deflector 210. Therefore, the air conditioner indoor unit 001 having the first transverse air deflector 200 of the present application can meet diversified air supply requirements.

[0050] With continued reference to Figures 1 to 3 The outer air deflector 210 includes the first air guide plate segment 211 and the second air guide plate segment 212. The inner air deflector 220 is arranged on the side of the first air guide plate segment 211 close to the second air guide plate segment 212, and one extension direction of the inner air deflector 220 points to the second air guide plate segment 212, so that the air flow between the first air guide plate segment 211 and the inner air deflector 220 can change direction through the second air guide plate segment 212.

[0051] As can be understood by those skilled in the art, when the air flow flows between the first air guide plate segment 211 and the inner air deflector 220, the flow rate and the flow direction are relatively stable due to the restriction of the first air guide plate segment 211 and the inner air deflector 220, and the air flow is not interfered by other air flows. When the part of the stable air flow flows to the second air guide plate segment 212, the air flow can be changed in direction as a whole by the second air guide plate segment 212, so that the part of the stable air flow can be blown to a certain area in the room where the air conditioner indoor unit 001 is located in a relatively concentrated manner.

[0052] As Figure 2 shown, in some embodiments of the present application, the inner air deflector 220 can be provided as an arc-shaped plate, and the convex side of the inner air deflector 220 faces the first flow guide plate segment 211, so as to reduce the air resistance of the airflow between the first flow guide plate segment 211 and the inner air deflector 220.

[0053] As Figures 1 to 3 can be seen, in some embodiments of the present application, the length of the first flow guide plate segment 211 is less than or equal to the length of the second flow guide plate segment 212, so that the airflow between the first flow guide plate segment 211 and the inner air deflector 220 has a longer guiding distance when flowing through the second flow guide plate segment 212, effectively avoiding the airflow from being easily diverged when changing direction.

[0054] Further, the length of the inner air deflector 220 is less than or equal to the length of the first flow guide plate segment 211, so as to avoid the air outlet port between the inner air deflector 220 and the first flow guide plate segment 211 being too small and causing wind noise while the inner air deflector 220 and the first flow guide plate segment 211 jointly restrict the airflow.

[0055] As Figure 1 , Figure 4 and Figure 5 shown, in some embodiments of the present application, the rotation axis 201 of the first transverse air deflector 200 is located below the front of the air outlet 1121, so that the first transverse air deflector 200 can be rotated to a position in which the inner air deflector 220 is aligned with the lower end of the air outlet 1121, and a position in which the outer air deflector 210 is aligned with the lower end of the air outlet 1121, thereby extending the air outlet air duct 112 through the inner air deflector 220.

[0056] As Figures 1 to 3 shown, in some embodiments of the present application, the rotation axis 201 is located at the bending position of the first transverse air deflector 200.

[0057] As Figure 2 shown, the first motor 300 is used to drive the first transverse air deflector 200 to rotate around the rotation axis 201, so as to change the posture of the first transverse air deflector 200, thereby realizing different air supply modes of the air conditioner indoor unit 001 (as shown in Figures 4 to 8 ).

[0058] In some embodiments of the present application, the first motor 300 and the first transverse air deflector 200 can be directly drivingly connected, or can be connected through other transmission mechanisms.

[0059] As an example one, the housing of the first motor 300 is fixedly mounted to the casing 110, and the rotating shaft of the first motor 300 is coaxial with the rotating axis 201 of the first transverse air deflector 200.

[0060] As an example two, the housing of the first motor 300 is fixedly mounted to the casing 110, and the rotating shaft of the first motor 300 is coaxial with the rotating axis 201 of the first transverse air deflector 200.

[0061] Further, the first motor 300 can be a self-locking motor, so as to prevent the first transverse air deflector 200 from rotating under the action of the air flow, thereby ensuring that the position of the first transverse air deflector 200 is basically unchanged in different air supply modes, and further ensuring the reliability of the air supply mode of the air conditioner indoor unit 001.

[0062] Still further, the first motor 300 can also be a stepping motor, so as to ensure that the first transverse air deflector 200 can be accurately rotated to Figures 4 to 8 the position shown.

[0063] As shown in Figure 1 and Figure 2 in some embodiments of the present application, the second transverse air deflector 400 can be located above the first transverse air deflector 200, and the second motor 500 is used to drive the second transverse air deflector 400 to rotate.

[0064] Exemplarily, both ends of the second transverse air deflector 400 in the length direction (left-right direction) are respectively provided with a plate-shaped structure or a rod-shaped structure, and a rotating shaft is arranged on the plate-shaped structure or the rod-shaped structure. The casing 110 is provided with a shaft hole matched with the rotating shaft. The rotating shaft of the second transverse air deflector 400 is rotatably inserted into the shaft hole, so as to mount the second transverse air deflector 400 to the casing 110.

[0065] As shown in Figure 1 , the shortest distance L2 between the two ends of the second transverse air deflector 400 is greater than the shortest distance L1 between the two ends of the outer air deflector 210 in the path of the air flow, so that the second transverse air deflector 400 has sufficient air deflection performance.

[0066] The connection mode between the second motor 500 and the second transverse air deflector 400 can refer to the description of the first motor 300 and the first transverse air deflector 200.

[0067] As shown in Figures 4 to 8As shown, in some embodiments of this utility model, the second transverse air guide plate 400 and the first transverse air guide plate 200 can be rotated to a position where they are both tilted downwards and interfere with each other in the extension direction of the air outlet duct 112, so that the airflow blown out from the air outlet 1121 blows towards the lower part of the air conditioner indoor unit 001.

[0068] like Figures 4 to 8 As shown, in some embodiments of this utility model, the combination of the first horizontal air guide plate 200 and the second horizontal air guide plate 400 can enable the air conditioner indoor unit 001 to have five air supply modes.

[0069] like Figure 4 As shown, in the first air supply mode, the first horizontal air guide plate 200 and the second horizontal air guide plate 400 provide minimal obstruction to the airflow, resulting in the maximum air volume in this mode. This air supply mode can be applied to both cooling and heating of the indoor unit 001 of the air conditioner.

[0070] like Figure 5 As shown, in the second air supply mode, the first horizontal air guide plate 200 and the second horizontal air guide plate 400 can guide the airflow to the front and upper part of the indoor unit 001 of the air conditioner, and siphon in a portion of the ambient air (such as... Figure 5 The dashed line running through the first air intake plate section 211 and the inner air guide plate 220. This air supply mode can be applied to the cooling of the indoor unit 001 of the air conditioner.

[0071] like Figure 6 As shown, in the third air supply mode, the first horizontal air guide plate 200 and the second horizontal air guide plate 400 can guide the airflow to the front and lower part of the air conditioner indoor unit 001 and siphon in a portion of the ambient air. This air supply mode can be used for cooling of the air conditioner indoor unit 001. It is especially suitable for air conditioner indoor units 001 installed at the head of beds, as it can prevent cold air from blowing directly on the user's head.

[0072] like Figure 7 As shown, in the fourth air supply mode, the first horizontal air guide plate 200 and the second horizontal air guide plate 400 can guide the airflow to the area below the indoor unit 001. This air supply mode can be used for either cooling or heating of the indoor unit 001. It is particularly suitable for indoor units 001 installed at the foot of a bed, preventing cold air from blowing directly onto the user's head.

[0073] like Figure 8 As shown, in the fifth air supply mode, the first horizontal air guide plate 200 and the second horizontal air guide plate 400 can also guide the airflow to the area below the indoor unit 001 of the air conditioner, and the airflow is relatively dispersed. This air supply mode can be applied to the heating or cooling of the indoor unit 001 of the air conditioner.

[0074] In addition, in other embodiments of the present application, the person skilled in the art can also omit the setting of the second horizontal air deflector 400 and the second motor 500 according to the needs.

[0075] Based on the foregoing description, the person skilled in the art can understand that the air conditioner indoor unit 001 of the present application can provide more air supply modes and diversified air supply needs for users.

[0076] So far, the technical solutions of the present application have been described in combination with the foregoing embodiments, but the person skilled in the art can easily understand that the protection scope of the present application is not limited to these specific embodiments. Without deviating from the technical principles of the present application, the person skilled in the art can disassemble and combine the technical solutions in each of the above embodiments, or make equivalent changes or replacements to the related technical features, and any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application will fall within the protection scope of the present application.

[0077] Finally, it needs to be pointed out that in the present application, the term "communication" means fluid communication to allow fluid (such as air, liquid) to flow between two things in communication with each other. And this "communication" can be fluid leakage-free, flowing between two things in communication with each other, or it can be fluid leakage, flowing between two things in communication with each other.
