[0002] An air conditioner is a device used to regulate and control parameters such as temperature, humidity, and airflow speed of the air inside a building or structure. It is one of the most common electrical appliances in people's daily lives. An air conditioner typically consists of an outdoor unit and an indoor unit. Depending on the installation method, indoor units can be divided into several types, such as wall-mounted, floor-standing, and ceiling-mounted. Among these, wall-mounted indoor units are characterized by their small footprint, ease of use, and high cost-effectiveness, making them the preferred type for ordinary households and widely used.

[0003] Existing wall-mounted air conditioner indoor units typically have a single air outlet on the front or bottom to deliver airflow. However, this single outlet design has some limitations. In cooling mode, because cold air is denser, the cold air delivered by the indoor unit naturally sinks and blows directly onto people, causing discomfort. In heating mode, because hot air is less dense, the hot air delivered by the indoor unit tends to rise, making it difficult to effectively heat the lower half of the room, thus affecting the overall heating effect and comfort.

The control device is electrically connected to the internal air guide assembly 3 and is configured to control the operation of the internal air guide assembly 3 to guide the air inside the air duct 2 to flow to the upper air outlet 11 and / or the lower air outlet 12.

[0044] like Figure 4 and Figure 6As shown, the internal air guide assembly 3 includes a first internal air guide assembly 31, a second internal air guide assembly 32, and an internal air guide housing 33. The first internal air guide assembly 31 and the second internal air guide assembly 32 are spaced apart inside the internal air guide housing 33 along the height direction of the indoor unit of the air conditioner. The first internal air guide assembly 31 and the second internal air guide assembly 32 are electrically connected to a control device. The control device can control the first internal air guide assembly 31 to operate to guide the air inside the air duct 2 to flow to the upper air outlet 11 or the lower air outlet 12. The control device can also control the second internal air guide assembly 32 to operate to guide the air inside the air duct 2 to flow to the upper air outlet 11 or the lower air outlet 12.

[0045] In some specific embodiments, the first internal air guide assembly 31 includes at least two first internal air guide sub-assemblies arranged along the length of the indoor unit of the air conditioner.

[0046] In some specific embodiments, the second internal air guide assembly 32 includes at least two second internal air guide sub-assemblies arranged along the length of the indoor unit of the air conditioner.

[0047] like Figure 5 and Figure 7 As shown, the first internal air guide assembly 31 includes a first internal drive device 311 and a first internal air guide member 312. The first internal drive device 311 is driven to the first internal air guide member 312 to drive the first internal air guide member 312 to rotate around an axis. The first internal drive device 311 is electrically connected to a control device. The control device can control the rotation angle of the first internal air guide member 312 through the first internal drive device 311 to guide the air inside the air duct 2 to flow to the upper air outlet 11 or the lower air outlet 12.

[0048] Further reference Figure 5 and Figure 7 The first internal air guide component 312 includes a plurality of first internal air guide sub-components 3121 arranged at intervals along the height direction of the indoor unit of the air conditioner. The first internal drive device 311 is drivenly connected to the plurality of first internal air guide sub-components 3121 to synchronously drive the plurality of first internal air guide sub-components 3121 to swing around the axis.

[0049] It should be noted that the number of the first inner air guide component 3121 is not limited to the three shown in the figure, but can be two, four, five, etc.

[0050] like Figure 5 and Figure 7As shown, the second internal air guide assembly 32 includes a second internal drive device 321 and a second internal air guide member 322. The second internal drive device 321 is driven to the second internal air guide member 322 to drive the second internal air guide member 322 to rotate around an axis.

[0051] Further reference Figure 5 and Figure 7 The second internal air guide component 322 includes a plurality of second internal air guide sub-components 3221 arranged at intervals along the height direction of the indoor unit of the air conditioner. The second internal drive device 321 is drivenly connected to the plurality of second internal air guide sub-components 3221 to synchronously drive the plurality of second internal air guide sub-components 3221 to swing around the axis.

[0052] It should be noted that the number of the first inner air guide component 3121 is not limited to the three shown in the figure, but can be two, four, five, etc.

[0053] like Figure 8 As shown, the indoor unit of the air conditioner also includes a straight-plate heat exchanger 5, which is connected to the compressor of the outdoor unit, allowing refrigerant to enter the straight-plate heat exchanger 5 for heating or cooling. The straight-plate heat exchanger 5 is located inside the outer casing 1 and in the air inlet section of the air duct 2, i.e., downstream of the axial fan 4. It should be noted that the straight-plate heat exchanger 5 has a compact structure, occupies little space, and is easy to maintain and clean.

[0054] Continue to refer to Figure 8 The indoor unit of the air conditioner also includes a filter 6, which is located between the upstream side of the axial fan 4 and the air inlet 13 of the outer casing 1. By setting the filter 6, dust, flying insects and other impurities in the air can be filtered out, preventing the air duct 2 from being blocked, and ensuring that the air discharged from the indoor unit of the air conditioner is clean.

[0055] The working principle of the indoor unit of this air conditioner is as follows:

[0056] When air needs to be discharged from the upper air outlet 11 of the indoor unit of the air conditioner, such as Figure 9 As shown, the control device controls the first internal drive device 311 to drive the first internal air guide component 312 to swing upward around the axis, and at the same time controls the second internal drive device 321 to drive the second internal air guide component 322 to swing upward around the axis, so that the first internal air guide component 312 and the second internal air guide component 322 can guide the air inside the air duct 2 to flow upward to the air outlet 11, and finally the air is discharged from the upper air outlet 11.

[0057] It should be noted that if the indoor unit of the air conditioner in this situation delivers cold air, it can prevent the cold air from blowing directly on people in front of, below, or directly below the unit, thus avoiding discomfort caused by direct cold air blowing on the body and improving the user experience. Furthermore, in other application scenarios, depending on the actual usage, the indoor unit of the air conditioner can also deliver hot air in this situation.

[0058] When air needs to be discharged from the lower air outlet 12 of the indoor unit of the air conditioner, such as Figure 10 As shown, the control device controls the first internal drive device 311 to drive the first internal air guide component 312 to swing downward around the axis, and at the same time controls the second internal drive device 321 to drive the second internal air guide component 322 to swing downward around the axis, so that the first internal air guide component 312 and the second internal air guide component 322 can guide the air inside the air duct 2 to flow downward to the air outlet 12, and finally the air is discharged from the lower air outlet 12.

[0059] It should be noted that if the indoor unit of the air conditioner delivers hot air in this situation, it can effectively heat the lower half of the indoor space, improving heating efficiency and user experience. Furthermore, in other application scenarios, depending on the actual usage, the indoor unit can also deliver cold air in this situation.

[0060] When it is necessary for the upper air outlet 11 and lower air outlet 12 of the indoor unit of the air conditioner to discharge air simultaneously, such as Figure 11 As shown, the control device controls the first internal drive device 311 to drive the first internal air guide component 312 to swing upward around the axis, while controlling the second internal drive device 321 to drive the second internal air guide component 322 to swing downward around the axis. This allows the first internal air guide component 312 to guide the air inside the air duct 2 to flow upward to the air outlet 11, and the second internal air guide component 322 to guide the air inside the air duct 2 to flow downward to the air outlet 12, ultimately causing the upper air outlet 11 and the lower air outlet 12 to discharge air simultaneously.

[0061] It should be noted that in this situation, the indoor unit of the air conditioner can evenly deliver cold or hot air into the room, thereby making the indoor temperature uniform, avoiding some areas being too cold or too hot, improving the user experience, and improving the efficiency of indoor cooling or heating.

[0062] The wall-mounted air conditioner indoor unit provided by this utility model guides the air inside the air duct 2 to flow to the upper air outlet 11 and / or the lower air outlet 12 by setting the internal air guide component 3. This allows it to better adapt to the operating conditions of the air conditioner. When the indoor unit is cooling, the upper air outlet 11 can be opened to reduce the discomfort of cold air directly hitting the human body. When the indoor unit is heating, the lower air outlet 12 can be opened to deliver hot air to the lower half of the indoor space as much as possible, thereby improving the uniformity of heating and cooling in the entire space and thus improving the user's comfort.

[0063] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
