[0002] Some air conditioner indoor units are equipped with multiple fans to achieve higher cooling and heating efficiency. These fans are spaced apart and arranged in a nearly symmetrical manner. Therefore, when the fans are rotating, the heat exchanger can only receive airflow from the rectangular air outlets of the fans, while the airflow escaping into the area between the fans flows slowly. This results in poor heat exchange in the area of ​​the heat exchanger facing the fans, and the airflow cannot fully exchange heat, thus reducing cooling and heating efficiency.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0038] This application provides an indoor air conditioning unit to address the problem of reduced cooling and heating efficiency. The following description, in conjunction with the accompanying drawings, will illustrate this solution.

[0039] In the embodiments of this application, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the indoor unit of the air conditioner includes:

[0040] The fan assembly 1 includes a plurality of fans 11 arranged side by side at intervals, each fan 11 having an air outlet 111; and,

[0041] The flow guide 2 is provided with multiple flow guide channels 23;

[0042] Among them, multiple guide channels 23 correspond one-to-one with multiple fans 11. The first end of the guide channel 23 is sealed and connected to the air outlet 111, and the second end of the guide channel 23 is used to face the heat exchanger 3.

[0043] Understandably, through the guide channel 23 which is sealed to the air outlet 111 of the fan 11, the airflow generated by the fan 11 is concentrated and sent to the heat exchanger 3, which prevents the airflow from escaping between adjacent fans 11 and reduces the generation of turbulence, reduces the loss of air volume and velocity, and ensures that the airflow that exchanges heat through the heat exchanger 3 has a large velocity and a high flow rate, thereby providing a large volume of cold air and hot air and ensuring cooling and heating efficiency.

[0044] In some embodiments, such as Figure 3 and Figure 4 As shown, the flow guide 2 includes a flow guide shell 21 and a plurality of baffles 22. The plurality of baffles 22 are spaced apart inside the flow guide shell 21. Adjacent baffles 22 and the flow guide shell 21 enclose a flow guide channel 23. Each baffle 22 faces between any two adjacent fans 11.

[0045] It is understood that the baffle 22 blocks the airflow from flowing between adjacent fans 11 and guides the airflow to the heat exchanger 3. For example, multiple baffles 22 may be arranged at equal or unequal intervals in the guide shell 21, and the end of the baffle 22 facing the fan 11 should be the end that is in close contact with the air outlet 111, and the end of the baffle 22 facing the heat exchanger 3 should preferably be in contact with the surface of the heat exchanger 3 to prevent airflow from flowing between the baffle 22 and the heat exchanger 3.

[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, the fan assembly 1 also includes a dual-shaft motor 12 for driving multiple fans 11, and multiple partitions 22 are respectively a first partition and a second partition. The first partition is disposed facing the dual-shaft motor 12, and the second partition is located between adjacent fans 11.

[0047] It should be noted that the dual-axis motor 12 refers to a motor with two mechanical axes, which can realize the independent transmission of energy between the two mechanical axes. Each mechanical axis is connected to at least one fan 11. Generally speaking, the number of fans 11 connected to the two mechanical axes is the same, and the fans 11 are arranged at equal intervals.

[0048] Understandably, since the distance between the fans 11 located on both sides of the dual-shaft motor 12 is different from the distance between other adjacent fans 11, the first partition and the second partition are used to specifically block the airflow and improve the reliability of the guide component 2.

[0049] In some embodiments, such as Figure 5As shown, the flow guide shell 21 includes a cover plate 211 and a bottom plate 212 arranged vertically opposite each other, and two baffles 213 arranged horizontally opposite each other. The cover plate 211 and the bottom plate 212 are connected between the two baffles 213. The bottom plate 212 is inclined to the cover plate 211, and the width of the bottom plate 212 is smaller than the width of the cover plate 211.

[0050] It should be noted that "vertical relative setting" and "horizontal relative setting" both refer to the positional relationship when the indoor unit of the air conditioner is in the correct installation posture, which means that the length direction of the indoor unit of the air conditioner is horizontal. "The base plate 212 is inclined to the cover plate 211" means that there is an angle between the base plate 212 and the cover plate 211.

[0051] It is understandable that, through the above design, the guide shell 21 gradually becomes larger along the direction of the fan 11 near the heat exchanger 3; and, since the bottom plate 212 is inclined to the cover plate 211, the size of the opening of the guide shell 21 facing the heat exchanger 3 can be increased in a limited space, so that the opening of the guide shell 21 facing the heat exchanger 3 can cover the surface of the heat exchanger 3 as much as possible.

[0052] For example, the base plate 212 is inclined to the cover plate 211 in a direction away from the cover plate 211, and it can be imagined that the guide shell 21 is approximately trumpet-shaped. Alternatively, the base plate 212 is inclined to the cover plate 211 in a direction close to the cover plate 211, in which case the guide shell 21 gradually shrinks. However, by designing the width of the base plate 212 and the cover plate 211, the opening of the guide shell 21 facing the heat exchanger 3 can be made larger than the opening of the guide shell 21 facing the fan 11, thereby increasing the airflow velocity while covering the surface of the heat exchanger 3 as much as possible.

[0053] For example, the air guide 2 can be fixed to the end of the air outlet 111 in a detachable connection manner, such as a snap-fit ​​connection or a screw connection.

[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, the heat exchanger 3 is inclined, the cover plate 211 is connected to the upper edge of the heat exchanger 3, the bottom plate 212 is connected to the lower edge of the heat exchanger 3, and the two baffles 213 are respectively connected to the left and right edges of the heat exchanger 3.

[0055] It should be noted that the tilt setting of heat exchanger 3 means that heat exchanger 3 is tilted in the horizontal direction relative to the indoor unit of the air conditioner when it is in the correct installation posture. The top edge, bottom edge, left edge, and right edge all refer to the edges of the indoor unit of the air conditioner in their respective positions when it is in the correct installation posture.

[0056] It is understandable that by connecting the cover plate 211, the bottom plate 212 and the two baffles 213 to the edge of the heat exchanger 3 respectively, the flow of air between the air guide 2 and the heat exchanger 3 is obstructed.

[0057] In some embodiments, such as Figure 5 and Figure 6 As shown, the partition 22 includes a heat insulation body 221, a noise reduction layer 222, and a heat insulation layer 223. The noise reduction layer 222 covers at least a portion of the heat insulation body 221, and the heat insulation layer 223 covers the noise reduction layer 222.

[0058] It should be noted that the insulation layer 221 refers to a structure with a heat-insulating function. The noise reduction layer 222 refers to a structure that reduces noise transmission. The heat insulation layer 223 refers to a structure that reduces heat conduction. "The heat insulation layer 223 covers the noise reduction layer 222" means that the noise reduction layer 222 is hidden under the heat insulation layer 223 and is not exposed.

[0059] Understandably, the insulation 221 reduces the thermal conductivity of the partition 22, making it less likely for condensation to form on the surface of the partition 22 when airflow passes through the guide channel 23 in humid or high-temperature air environments. The noise reduction layer 222 reduces the noise generated by airflow and collision within the guide shell 21. The heat insulation layer 223 reduces heat conduction between the noise reduction layer 222 and the heat exchanger 3, reducing the temperature impact of the heat exchanger 3 on the partition 22, and also serves to insulate the heat exchanger 3.

[0060] For example, the insulation body 221 is made of foam plastic to reduce temperature changes; the noise reduction layer 222 is made of noise reduction cotton; and the heat insulation layer 223 is made of aluminum foil. Both the first and second partitions include the insulation body 221, the noise reduction layer 222, and the heat insulation layer 223, the only difference between them being their dimensions. Specifically, the first and second partitions can adopt a structure similar to a triangular pyramid.

[0061] In some embodiments, such as Figure 4 As shown, the noise reduction layer 222 covers the surface of the insulation body 221 facing the heat exchanger 3, as well as the surface of the insulation body 221 located inside the flow guide shell 21.

[0062] It is understandable that since the airflow does not flow over the surface of the insulation 221 facing the adjacent fan 11, it is only necessary to cover the surface of this embodiment with the noise reduction layer 222. Furthermore, based on descriptions in other embodiments, it is known that the heat insulation layer 223 covers the noise reduction layer 222, meaning that the airflow will contact the heat insulation layer 223 when it flows through the baffle 22. Since the heat insulation layer 223 can be made of tin foil, the smooth surface of the tin foil can effectively reduce the resistance of the guide channel 23.

[0063] In some embodiments, such as Figure 4 As shown, the guide channel 23 gradually increases in size along the direction from the fan 11 to the heat exchanger 3.

[0064] It should be noted that the direction in this embodiment refers to a virtual direction. It is understood that the gradually increasing size of the guide channel 23 allows the airflow to contact the surface of the heat exchanger 3 as much as possible, thereby improving the cooling and heating effect.

[0065] In some embodiments, such as Figure 4 As shown, along the direction of the partition 22 near the heat exchanger 3, the partition 22 gradually becomes smaller.

[0066] It should be noted that, based on the gradual increase in the size of the guide channel 23, the width of the baffle 22 should gradually decrease along the axial direction of the fan 11. Understandably, according to the Coanda effect, the airflow will flow along the wall. The surface of the baffle 22 guides the airflow towards the heat exchanger 3, ensuring that the surface of the heat exchanger 3 can fully contact the airflow, increasing the ratio of the actual heat exchange area to the theoretical heat exchange area, and maximizing the utilization of the heat exchanger 3.

[0067] In some embodiments, such as Figure 4 As shown, the indoor unit of the air conditioner also includes a housing 4, and the fan assembly 1, the air guide 2 and the heat exchanger 3 are all disposed inside the housing 4.

[0068] This application also provides an air conditioner, which includes the above-mentioned indoor unit and outdoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
