[0002] In recent years, with the improvement of people's living standards and the continuous global warming, air conditioning has become an important home appliance for people to get through the summer, especially at night when they can't rest without it. However, the airflow from existing air conditioners is not gentle enough, and when the air blows directly on the body, the comfort level is poor, and it can even easily lead to illness. Currently, most home air conditioners are installed directly facing the bed, so when the air conditioner is turned on, the air blows directly on the body. If the air conditioner blows directly on the head and neck, the scalp temperature will drop, causing dizziness and headaches; if the air conditioner blows directly on the face for a long time, it can easily lead to facial paralysis; if the air conditioner blows on other parts of the body for a long time, it can easily cause colds and other illnesses.

[0003] It is evident that existing air conditioning technologies suffer from poor airflow comfort, and no effective solution has yet been proposed to address this issue. Utility Model Content

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Please refer to Figures 1 to 2 To achieve the above objectives, an embodiment of this utility model provides an indoor air conditioning unit, which includes: a housing 1, a heat exchanger 2, and a fan 3. The housing 1 has a main chamber 10 inside, and the housing 1 is provided with a first air inlet duct 11, a second air inlet duct 12, and an air outlet duct 13. The first end of the first air inlet duct 11, the first end of the second air inlet duct 12, and the first end of the air outlet duct 13 are all connected to the main chamber 10, and the second end of the first air inlet duct 11, the second end of the second air inlet duct 12, and the second end of the air outlet duct 13 are all connected to the external space of the housing 1. The heat exchanger 2 is disposed in the first air inlet duct 11, or the heat exchanger 2 is disposed in the main chamber 10 and corresponds to the position of the first end of the first air inlet duct 11. The fan 3 is disposed in the main chamber 10, and the fan 3 can drive air to flow into the main chamber 10 from the first air inlet duct 11 and the second air inlet duct 12 and flow out from the air outlet duct 13.

[0023] The indoor air conditioner unit with this structural design incorporates a first air inlet duct 11 and a second air inlet duct 12 on the casing 1. Indoor air is drawn in through the first air inlet duct 11 and exchanged heat with the heat exchanger 2. The heat-exchanged air mixes with the air exiting through the second air inlet duct 12 in the main chamber 10. The mixed air is then discharged into the room through the outlet duct 13. By connecting the first ends of the first air inlet duct 11 and the first ends of the second air inlet duct 12 to the main chamber 10, the air heated by the heat exchanger 2 mixes with room temperature air within the main chamber 10. Driven by the fan 3, the two airs mix more thoroughly within the main chamber 10, thereby improving the uniformity of the mixed air temperature. The mixed air is then blown into the room through the outlet duct 13, effectively improving the gentleness of the airflow, reducing discomfort caused by direct airflow from the air conditioner, enhancing the user experience, and solving the technical problem of poor airflow comfort in related technologies.

[0024] The first and second ends of each of the above-mentioned air ducts are the two ports of the corresponding air ducts. For the first air inlet duct 11 and the second air inlet duct 12, the second end is the air inlet and the first end is the air outlet. That is, air enters the air duct through the second end and flows out of the air duct through the first end. For the air outlet duct 13, the first end is the air inlet and the second end is the air outlet. That is, air enters the air outlet duct 13 through the first end and flows out through the second end.

[0025] In a preferred embodiment, the fan 3 is a cross-flow fan, thereby increasing the air volume and air outlet area, and reducing the noise during air conditioner operation.

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, the first end of the second air inlet duct 12 is located on the side of the fan 3 away from the air outlet duct 13, and the opening of the first end of the second air inlet duct 12 is set towards the fan 3.

[0027] By setting the first end of the second air inlet duct 12 on the side of the fan 3 away from the air outlet duct 13, its air outlet position is located before the position where the fan 3 is working. After the normal temperature air in the second air inlet duct 12 flows out, it is mixed and accelerated together with the air that has been heated by the heat exchanger 2 by the fan 3, and then flows out through the air outlet duct 13. This can more fully mix the two parts of air, further improve the uniformity of the air outlet temperature, and ensure the comfort of the air outlet.

[0028] In actual implementation, the specific locations of the first air inlet duct 11 and the second air inlet duct 12 can be flexibly arranged according to design requirements.

[0029] In a preferred embodiment, the first end of the first air inlet duct 11 and the first end of the second air inlet duct 12 are arranged sequentially along the circumference of the fan 3. As a preferred implementation, the first end of the first air inlet duct 11 and the first end of the second air inlet duct 12 are arranged sequentially along the circumference of the fan 3. In this way, when the fan 3 is running, it drives the air nearby to move circumferentially, which is more conducive to mixing the two parts of air with different temperatures and improves the uniformity of mixing.

[0030] In a preferred embodiment, the first end of the first air inlet duct 11 and the first end of the second air inlet duct 12 are arranged sequentially along the rotation direction of the fan 3.

[0031] In this embodiment, as Figures 1 to 2 As shown, the air flowing out of the first air inlet duct 11 is heated by the heat exchanger 2 and then meets the room temperature air flowing out of the second air inlet duct 12 under the drive of the fan 3. They are mixed before being discharged through the air outlet duct 13. This design will not affect the arrangement of the heat exchanger 2 and the air supply. Moreover, the air after being heated by the heat exchanger 2 is mixed more thoroughly with the room temperature air, which can effectively improve the comfort of the air conditioning.

[0032] The indoor unit of the air conditioner also includes a valve structure 4, which is located in the second air inlet duct 12 to control the air flow in the second air inlet duct 12.

[0033] By setting a valve structure 4 at the second air inlet duct 12, the air flow rate in the second air inlet duct 12 can be controlled by the valve structure 4, thereby adjusting the content of room temperature air participating in the mixing, so as to achieve the purpose of adjusting the gentleness of the air outlet. In actual use, the user can adjust the opening of the valve structure 4 according to their own physical condition, so that the air outlet reaches a comfortable temperature.

[0034] Specifically, the valve structure 4 is installed in the second air inlet duct 12. Its specific location is not limited here and can be installed at any location in the second air inlet duct 12, such as at the inlet, inside the duct, at the outlet, etc.

[0035] The valve structure 4 is located at the first end of the second air inlet duct 12. The valve structure 4 includes a baffle plate, which is rotatably arranged around a preset axis, wherein the preset axis is parallel to the central axis of the fan 3.

[0036] In this embodiment, the valve structure 4 is designed to include a baffle plate that can rotate around a preset axis. By rotating the baffle plate, the air in the second air inlet duct 12 can be blocked or avoided, thereby regulating the airflow. Furthermore, the baffle plate is located at one end of the second air inlet duct, guiding the airflow and thus regulating the direction of the room temperature air flowing out of the second air inlet duct 12. This allows for flexible control of the baffle plate according to the air conditioner's operating status, enabling better mixing of hot and cold air.

[0037] In addition, the indoor unit of the air conditioner includes: a rotary drive assembly, which is connected to the baffle plate to drive the baffle plate to rotate; and a control circuit board, which is electrically connected to the rotary drive assembly and controls the operation of the rotary drive assembly.

[0038] In a preferred embodiment, the first end of the second air inlet duct 12 is oriented toward the first direction, and the line connecting the center of the fan 3 and the midpoint of the first end of the second air inlet duct 12 extends along the second direction, with the angle between the first direction and the second direction not exceeding 10°.

[0039] To ensure effective mixing of room temperature air with the air after heat exchange in heat exchanger 2, the orientation of the first port of the second air inlet duct 12 is designed such that the angle between the port and the line connecting the center of the fan 3 and the midpoint of the first port of the second air inlet duct 12 is less than or equal to 10°. This ensures that the room temperature air flowing out of the second air inlet duct 12 is more fully directed toward the fan 3, thereby better mixing with the air flowing out of the heat exchanger 2 under the drive of the fan 3, thus ensuring the comfort of the air conditioning output.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the second air inlet duct 12 has a flared section 121, which is located at the second end of the second air inlet duct 12. Along the direction toward the outside of the air conditioner indoor unit, the area of ​​the flow cross section of the flared section 121 gradually increases.

[0041] By designing an flared section 121 at the air inlet of the second air inlet duct 12, it is beneficial to ensure that indoor air enters the second air inlet duct 12 more smoothly, thereby ensuring the conditioning effect of the air after heat exchange in the air conditioner and improving the comfort of the air conditioner.

[0042] By connecting the first end of the first air inlet duct 11 and the first end of the second air inlet duct 12 to the main chamber 10, the air that has been heated by the heat exchanger 2 can be mixed with the room temperature air in the main chamber 10. Under the drive of the fan 3, the two can be mixed more thoroughly in the main chamber 10, thereby effectively improving the uniformity of the air temperature after mixing, which is beneficial to improving the comfort of the air conditioning.

[0043] In addition, an embodiment of this utility model also provides an air conditioning device, which includes an indoor air conditioning unit, and the indoor air conditioning unit is the aforementioned indoor air conditioning unit.

[0044] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0045] The indoor unit of the air conditioner according to an embodiment of the present invention includes: a housing 1, a heat exchanger 2, and a fan 3. The housing 1 has a main chamber 10 inside. The housing 1 is provided with a first air inlet duct 11, a second air inlet duct 12, and an air outlet duct 13. The first end of the first air inlet duct 11, the first end of the second air inlet duct 12, and the first end of the air outlet duct 13 are all connected to the main chamber 10. The second end of the first air inlet duct 11, the second end of the second air inlet duct 12, and the second end of the air outlet duct 13 are all connected to the external space of the housing 1. The heat exchanger 2 is disposed in the first air inlet duct 11, or the heat exchanger 2 is disposed in the main chamber 10 and corresponds to the position of the first end of the first air inlet duct 11. The fan 3 is disposed in the main chamber 10 and can drive air to flow into the main chamber 10 from the first air inlet duct 11 and the second air inlet duct 12 and flow out from the air outlet duct 13. The indoor air conditioner unit with this structural design incorporates a first air inlet duct 11 and a second air inlet duct 12 on the casing 1. Indoor air is drawn in through the first air inlet duct 11 and exchanged heat with the heat exchanger 2. The heat-exchanged air mixes with the air exiting through the second air inlet duct 12 in the main chamber 10. The mixed air is then discharged into the room through the outlet duct 13. By connecting the first ends of the first air inlet duct 11 and the first ends of the second air inlet duct 12 to the main chamber 10, the air heated by the heat exchanger 2 mixes with room temperature air within the main chamber 10. Driven by the fan 3, the two airs mix more thoroughly within the main chamber 10, thereby improving the uniformity of the mixed air temperature. The mixed air is then blown into the room through the outlet duct 13, effectively improving the gentleness of the airflow, reducing discomfort caused by direct airflow from the air conditioner, enhancing the user experience, and solving the technical problem of poor airflow comfort in related technologies.
