Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a wall-mounted air conditioner. Background Technology

[0002] In related technologies, traditional wall-mounted air conditioners typically have only one air duct, resulting in a single air outlet pattern. Regardless of the operating mode (such as heating and cooling), the airflow from a wall-mounted air conditioner always flows through the same duct, making the air outlet path indiscriminate and negatively impacting the user's indoor experience. Summary of the Invention

[0003] The main objective of this invention is to propose a wall-mounted air conditioner that addresses the technical problem of the single air outlet method in traditional wall-mounted air conditioners.

[0004] To achieve the above objectives, the present invention provides a wall-mounted air conditioner, comprising:

[0005] The housing includes an air inlet, an air outlet, a main air duct, and an auxiliary air duct; wherein the main air duct connects the air inlet and the air outlet; the auxiliary air duct includes an auxiliary air inlet connected to the main air duct and an auxiliary air outlet connected to the auxiliary air inlet; and

[0006] An air guide structure is movably disposed within the housing, and the air guide structure is used to guide the airflow from the main air duct to be blown out from at least one of the air outlet and the auxiliary air outlet.

[0007] In one embodiment, the housing includes a volute, a front volute tongue, and a front panel; wherein the volute and the front volute tongue enclose the main air duct; and the auxiliary air duct is formed between the front volute tongue and the front panel.

[0008] In one embodiment, the auxiliary air inlet is located at the end of the front volute away from the air outlet; the auxiliary air outlet is located on the front panel or at the end of the front volute close to the air outlet.

[0009] In one embodiment, the end of the auxiliary air duct near the auxiliary air outlet is inclined downward so that the auxiliary air outlet opens downward.

[0010] In one embodiment, the air guiding structure includes a first air guiding plate, which is movably disposed within the main air duct to regulate the airflow within the main air duct towards the air outlet or the auxiliary air outlet.

[0011] In one embodiment, the air guiding structure further includes a second air guiding plate, which is movably disposed in the auxiliary air duct for opening and closing the auxiliary air duct.

[0012] In one embodiment, the wall-mounted air conditioner has a cooling mode and a heating mode; wherein,

[0013] In the cooling mode, the first air guide plate moves to extend toward the air outlet, and the second air guide plate closes the auxiliary air duct to form a first air outlet path within the housing, passing through the main air duct to the air outlet.

[0014] In the heating mode, the first air guide plate moves to extend toward the auxiliary air inlet, and the second air guide plate opens the auxiliary air duct to form a second air outlet path within the housing, passing through the main air duct to the auxiliary air inlet and the auxiliary air outlet.

[0015] In one embodiment, one end of the first air guide plate is rotatably connected to the volute of the wall-mounted air conditioner; one end of the second air guide plate is rotatably connected to the front volute of the wall-mounted air conditioner, and the rotation axis of the second air guide plate is located on the side of the auxiliary air inlet near the air outlet; in the heating mode, the first air guide plate and the second air guide plate are spliced ​​together to guide the airflow in the main air duct to the auxiliary air duct.

[0016] In one embodiment, the air outlet is kept open to the external environment; the first air guide plate is located inside the main air duct and is spaced apart from the air outlet.

[0017] In one embodiment, the auxiliary air duct is arranged in a downward-curving arc along its air outlet direction.

[0018] In one embodiment, the wall-mounted air conditioner further includes a fan wheel installed inside the housing; the auxiliary air duct has an upper air duct wall and a lower air duct wall arranged opposite to each other, and the ratio of the diameter of the circle containing the lower air duct wall to the diameter of the fan wheel is in the range of [0.5, 0.7].

[0019] In one embodiment, the ratio of the diameter of the circle containing the upper wind tunnel wall to the diameter of the wind turbine is in the range of [0.8, 1.2].

[0020] The wall-mounted air conditioner of this application includes a housing and an air guide structure. The housing is provided with an air inlet, an air outlet, a main air duct, and an auxiliary air duct. The main air duct connects the air inlet and the air outlet. The auxiliary air duct is provided with an auxiliary air inlet connected to the main air duct and an auxiliary air outlet connected to the auxiliary air inlet. The air guide structure is movably disposed within the housing. The air guide structure is used to guide the airflow from the main air duct to be blown out from at least one of the air outlet and the auxiliary air outlet. This arrangement results in multiple air outlet paths within the wall-mounted air conditioner, such as a first air outlet path from the main air duct to the air outlet, and a second air outlet path from the main air duct to the auxiliary air inlet and the auxiliary air outlet. Of course, it can also be a third air outlet path formed by the first and second air outlet paths. That is, the airflow within the wall-mounted air conditioner can be selectively discharged from the first air outlet path, or from the second air outlet path, or from the third air outlet path. Wall-mounted air conditioners can select different air outlet paths in different operating modes. For example, in cooling mode, cold air is discharged from the first air outlet path; in heating mode, hot air is discharged from the second air outlet path; of course, in both cooling and heating modes, airflow can also be discharged from the third air outlet path, which is not limited here. Therefore, this application solves the technical problem of the single air outlet method in traditional wall-mounted air conditioners. Attached Figure Description

[0034] This application proposes a wall-mounted air conditioner that can solve the technical problem of the single air outlet mode of traditional wall-mounted air conditioners.

[0035] In one embodiment of this application, such as Figure 1 , Figure 3 and Figure 4As shown, the wall-mounted air conditioner includes a housing 100 and an air guiding structure 200. The housing 100 is provided with an air inlet 101, an air outlet 102, a main air duct 110, and an auxiliary air duct 120. The main air duct 110 connects the air inlet 101 and the air outlet 102. The auxiliary air duct 120 is provided with an auxiliary air inlet 121 connected to the main air duct 110 and an auxiliary air outlet 122 for connecting to the auxiliary air inlet 121 (e.g., ...). Figure 4 (as shown); the air guide structure 200 is movably disposed within the housing 100, and the air guide structure 200 is used to guide the airflow of the main air duct 110 out from at least one of the air outlet 102 and the auxiliary air outlet 122.

[0036] It is understood that the housing 100 includes a top plate, a bottom plate and a front panel 150. The top plate is provided with an air inlet 101 and an air outlet 102 can be provided on the front panel 150 or on the bottom plate. Of course, the air outlet 102 can also be provided between the bottom plate and the front panel 150. The specific location is not limited here. The air inlet 101 and the air outlet 102 are connected through the main air duct 110. The housing 100 is also equipped with a fan wheel 160 and a heat exchanger 170. The fan wheel 160 can be a cross-flow fan wheel 160. The fan wheel 160 is located in the main air duct 110. The heat exchanger 170 is located between the air inlet 101 and the fan wheel 160. The heat exchanger 170 is roughly V-shaped and wraps around the fan wheel 160 in a semi-enclosed manner. This arrangement allows the airflow entering from the air inlet 101 to flow along the main air duct 110 to the air outlet 102 after exchanging heat with the heat exchanger 170, thereby achieving the regulation of indoor temperature.

[0037] Furthermore, the auxiliary air duct 120 has an auxiliary air inlet 121 and an auxiliary air outlet 122. The auxiliary air inlet 121 is connected to the main air duct 110. The auxiliary air outlet 122 can be located inside the housing 100 to connect with the air outlet 102. Of course, the auxiliary air outlet 122 can also be located on the housing 100 so that the auxiliary air outlet 122 connects with the outside of the housing 100. That is, the location of the auxiliary air outlet 122 is not limited, as long as the auxiliary air outlet 122 can connect with the outside.

[0038] The specific shape and structure of the air guide structure 200 are not limited, as long as it can adjust the airflow direction of the wall-mounted air conditioner to guide the airflow from the main air duct 110 out of at least one of the air outlet 102 and the auxiliary air outlet 122. The air guide structure 200 can be movably housed within the housing 100 in various ways, such as, but not limited to, rotation or sliding; no specific limitation is made here. Since the air guide structure 200 is located inside the housing 100, it is not easily visible from the outside, thus avoiding visual clashes with the user when the air guide structure 200 is in motion, thereby improving the aesthetics of the wall-mounted air conditioner.

[0039] Furthermore, when the airflow enters the main air duct 110, because the auxiliary air inlet 121 of the auxiliary air duct 120 is connected to the main air duct 110, the airflow direction changes under the adjustment of the air guide structure 200. The airflow can enter the auxiliary air duct 120 from the main air duct 110 and be discharged into the room from the auxiliary air outlet 122 of the auxiliary air duct 120. Of course, under the adjustment of the air guide structure 200, a portion of the airflow can also flow along the main air duct 110 and be discharged outward from the air outlet 102, while another portion of the airflow flows along the main air duct 110 and enters the auxiliary air inlet 121, and is discharged outward from the auxiliary air outlet 122. The flow mode of the airflow is not specifically limited.

[0040] The wall-mounted air conditioner of this application includes a housing 100 and an air guide structure 200. The housing 100 is provided with an air inlet 101, an air outlet 102, a main air duct 110, and an auxiliary air duct 120. The main air duct 110 connects the air inlet 101 and the air outlet 102. The auxiliary air duct 120 is provided with an auxiliary air inlet 121 connected to the main air duct 110 and an auxiliary air outlet 122 connected to the auxiliary air inlet 121. The air guide structure 200 is movably disposed within the housing 100 and is used to guide the airflow from the main air duct 110 from the air outlet 102 and the auxiliary air outlet 122. With one less air outlet, this configuration creates multiple air outlet paths within the wall-mounted air conditioner. These include a first air outlet path 103, leading from the main air duct 110 to the air outlet 102, and a second air outlet path 104, leading from the main air duct 110 to the auxiliary air inlet 121 and auxiliary air outlet 122. Alternatively, a third air outlet path can be formed by the first and second air outlet paths 103 and 104. In other words, the airflow within the wall-mounted air conditioner can be selectively discharged from the first air outlet path 103, the second air outlet path 104, or the third air outlet path. Different air outlet paths can be selected for different operating modes. For example, in cooling mode, cold air is discharged from the first air outlet path 103; in heating mode, hot air is discharged from the second air outlet path 104. Of course, in both cooling and heating modes, airflow can also be discharged from the third air outlet path; the specific path is not limited here. Therefore, this application solves the technical problem of the single air outlet mode of traditional wall-mounted air conditioners.

[0041] Please see Figures 1 to 3 In one embodiment, the housing 100 includes a volute 130, a front volute tongue 140, and a front panel 150; wherein the volute 130 and the front volute tongue 140 enclose the main air duct 110; and the auxiliary air duct 120 is formed between the front volute tongue 140 and the front panel 150.

[0042] Understandably, the volute 130 and the front volute tongue 140 enclose and form the main air duct 110, and the impeller 160 is located between the volute 130 and the front volute tongue 140. The airflow blown by the impeller 160 can be blown out along the air duct to the air outlet 102. An auxiliary air duct 120 is formed between the front volute tongue 140 and the front panel 150. The auxiliary air duct 120 can be located on the front volute tongue 140, or it can be located on both the front volute tongue 140 and the front panel 150. That is, the auxiliary air duct 120 is located in the area where the front volute tongue 140 and the front panel 150 are located. The front volute tongue 140 can be assembled from multiple parts or it can be integrally molded. The specific details are not limited here. The auxiliary air inlet 121 can connect to the main air duct 110, allowing airflow to flow along the main air duct 110 and enter the auxiliary air duct 120 through the auxiliary air inlet 121, and then exit from the auxiliary air outlet 122 to the outside of the housing 100. This arrangement provides multiple air outlet paths, allowing cool air in cooling mode and hot air in heating mode to be blown outwards from different air outlet paths, thus improving the user's indoor experience. Furthermore, the auxiliary air duct 120 is formed between the front volute 140 and the front panel 150, making the area where the auxiliary air duct 120 is located reasonable and easy to process, thereby improving the space utilization rate within the housing 100.

[0043] Please see Figures 2 to 4 In one embodiment, the auxiliary air inlet 121 is located at the end of the front volute 140 away from the air outlet 102; the auxiliary air outlet 122 is located at the end of the front panel 150 or the front volute 140 near the air outlet 102. It is understood that the location of the auxiliary air inlet 121 at the end of the front volute 140 away from the air outlet 102 allows the auxiliary air inlet 121 to be close to the front end of the main air duct 110, meaning that the airflow within the main air duct 110 can quickly enter the auxiliary air inlet 121. The auxiliary air outlet 122 can be located on the front panel 150 or at the end of the front volute 140 near the air outlet 102, thereby facilitating communication between the auxiliary air outlet 122 and the outside of the housing 100. By defining the positions of the auxiliary air inlet 121 and the auxiliary air outlet 122 as described above, the distance between the auxiliary air inlet 121 and the auxiliary air outlet 122 is made larger, which is conducive to increasing the length of the auxiliary air duct 120 to meet different shapes of the auxiliary air duct 120, thereby facilitating the adjustment of the air outlet direction at the auxiliary air outlet 122.

[0044] In one embodiment, the auxiliary air duct 120 is inclined downwards at the end near the auxiliary air outlet 122, so that the auxiliary air outlet 122 opens downwards. It is understood that the open auxiliary air outlet 122 can also be connected to the air outlet 102. In this embodiment, in cooling mode, cold air is blown out of the air outlet 102 through the main air duct 110; in heating mode, hot air enters the auxiliary air inlet 121 through the main air duct 110 and is blown outwards from the auxiliary air outlet 122 of the auxiliary air duct 120. This arrangement makes it easier for cold air to form a cold airflow, while the downward-opening auxiliary air outlet 122 makes it easier for hot air to reach the ground and form a floor heating airflow. Floor heating airflow improves the user experience and avoids the situation of the user's head being hot and their feet being cold, thereby improving user comfort.

[0045] In one embodiment, the air guiding structure 200 includes a first air guide plate 210, which is movably disposed within the main air duct 110 to adjust the airflow within the main air duct 110 towards the air outlet 102 or the auxiliary air outlet 122. It is understood that the specific installation position of the first air guide plate 210 is not limited, as long as it can adjust the airflow direction within the main air duct 110, allowing the airflow within the main air duct 110 to blow out from the air outlet 102, or to guide the airflow within the main air duct 110 to the auxiliary air inlet 121 so that the airflow can blow out from the auxiliary air outlet 122. For example, one end of the first air guide plate 210 is located between the auxiliary air inlet 121 and the front panel 150, and is connected to the upper wall of the main air duct 110. At this time, the first air guide plate 210 can contact the lower wall of the main air duct 110 by rotating, thereby blocking the airflow from the main air duct 110. The airflow can then enter the auxiliary air duct 120 along the auxiliary air inlet 121 and then be blown out from the auxiliary air outlet 122. The first air guide plate 210 can also close the auxiliary air inlet 121 by rotating, so that the airflow can only be blown out of the air outlet 102 through the main air duct 110.

[0046] Please see Figures 1 to 3In one embodiment, the air guiding structure 200 further includes a second air guiding plate 220, which is movably disposed in the auxiliary air duct 120 for opening and closing the auxiliary air duct 120. It is understood that in this embodiment, the air guiding structure 200 includes a first air guiding plate 210 and a second air guiding plate 220. The second air guiding plate 220 can be disposed inside the auxiliary air duct 120, outside the auxiliary air duct 120, or at the intersection of the auxiliary air duct 120 and the main air duct 110, as long as the second air guiding plate 220 can open and close the auxiliary air duct 120. Correspondingly, the first air guiding plate 210 is disposed inside the main air duct 110. In this case, the first air guiding plate 210 only needs to be able to adjust the airflow direction within the main air duct 110 and guide the airflow within the main air duct 110 to the auxiliary air inlet 121; the specific location of the first air guiding plate 210 is not limited. By setting the first air guide plate 210 and the second air guide plate 220, it is beneficial to simplify the specific structure of the air guide structure 200, thereby facilitating the adjustment of the airflow direction.

[0047] Please see Figures 1 to 3 In one embodiment, the wall-mounted air conditioner has a cooling mode and a heating mode; wherein, in the cooling mode, the first air guide plate 210 is movable to extend toward the air outlet 102, and the second air guide plate 220 closes the auxiliary air duct 120 to form a first air outlet path 103 (e.g., through the main air duct 110 to the air outlet 102) within the housing 100. Figure 1 and Figure 2 (as shown); In the heating mode, the first air guide plate 210 moves to extend toward the auxiliary air inlet 121, and the second air guide plate 220 opens the auxiliary air duct 120 to form a second air outlet path 104 within the housing 100, passing through the main air duct 110 to the auxiliary air inlet 121 and the auxiliary air outlet 122 (as shown); Figure 3 (As shown).

[0048] Understandably, in cooling mode, the first air guide plate 210 extends towards the air outlet 102, and the second air guide plate 220 closes the auxiliary air duct 120. This allows the first air guide plate 210 to direct the airflow in the main air duct 110 to the air outlet 102. The movement of the first air guide plate 210 changes the airflow direction at the air outlet 102, thus changing the direction of the cold air output at the air outlet 102. Under the combined action of the first air guide plate 210 and the second air guide plate 220, the airflow in the main air duct 110 flows along the first air outlet path 103 from the main air duct 110 to the air outlet 102. The air outlet 102 is located at the bottom of the front panel 150, thereby allowing the cold air to be directed towards the front and / or upper front of the wall-mounted air conditioner, forming a canopy-like airflow.

[0049] In heating mode, the first air guide plate 210 extends towards the auxiliary air inlet 121, and the second air guide plate 220 opens the auxiliary air duct 120, allowing airflow to enter the auxiliary air inlet 121 along the main air duct 110 and then be discharged outward from the auxiliary air outlet 122. At this time, the hot air flows along the second air outlet path 104. The second air outlet path 104 has a different path from the first air outlet path 103, which is beneficial to improving the user experience. In this embodiment, the auxiliary air outlet 122 is open and connected to the air outlet 102, so that the hot air can be discharged towards the ground through the second air outlet path 104. That is, the hot air is more likely to reach the ground and form a floor heating airflow. The floor heating airflow is beneficial to improving the user experience and avoiding the situation of the user's head being hot and feet being cold, thereby improving the practicality of the wall-mounted air conditioner.

[0050] Please see Figures 1 to 3 In one embodiment, one end of the first air guide plate 210 is rotatably connected to the volute 130 of the wall-mounted air conditioner; one end of the second air guide plate 220 is rotatably connected to the front volute tongue 140 of the wall-mounted air conditioner, and the rotation axis of the second air guide plate 220 is located on the side of the auxiliary air inlet 121 near the air outlet 102; in the heating mode, the first air guide plate 210 and the second air guide plate 220 are spliced ​​together to guide the airflow in the main air duct 110 to the auxiliary air duct 120.

[0051] Specifically, the wall-mounted air conditioner also includes a first driving device and a second driving device. The first driving device is connected to the rotating shaft of the first air guide plate 210 to drive the first air guide plate 210 to rotate. The first driving device can be a first driving motor. The second driving device is connected to the rotating shaft of the second air guide plate 220 to drive the second air guide plate 220 to rotate. The second driving device can be a second driving motor.

[0052] Furthermore, one end of the first air guide plate 210 is provided with a first rotating shaft, which is located on the volute 130. The other end of the first air guide plate 210 is a first free end. By rotating around its first rotating shaft, the first free end of the first air guide plate 210 can rotate within the main air duct 110, thereby adjusting the airflow direction within the main air duct 110. One end of the second air guide plate 220 is provided with a second rotating shaft, which is located on the side of the auxiliary air inlet 121 near the air outlet 102. The other end of the second air guide plate 220 is a second free end. By rotating around its second rotating shaft, the second free end of the second air guide plate 220 can rotate within the main air duct 110 and close the auxiliary air inlet 121.

[0053] like Figure 3 and Figure 4As shown, in heating mode, when the first air guide plate 210 and the second air guide plate 220 are joined together by rotation, that is, the first free end of the first air guide plate 210 and the second free end of the second air guide plate 220 come into contact and abut against each other. This allows hot air to enter the auxiliary air duct 120 with the combined action of the first air guide plate 210 and the second air guide plate 220, and be discharged outward from the auxiliary air outlet 122. Therefore, this application achieves the function of allowing airflow to be discharged outward along different air outlet paths through the combined action of the first air guide plate 210 and the second air guide plate 220.

[0054] In addition, the first air guide plate 210 and the second air guide plate 220 of this application are both located inside the main air duct 110, and the rotation of the first air guide plate 210 and the second air guide plate 220 is not easily observed from the outside, thus avoiding the visual impact caused by the rotation of the first air guide plate 210 and the second air guide plate 220, which helps to improve the visual comfort of the wall-mounted air-conditioned room.

[0055] In one embodiment, the air outlet 102 is kept open to the external environment; the first air guide plate 210 is located within the main air duct 110 and is spaced apart from the air outlet 102. It can be understood that the air outlet 102 is kept open to the external environment, meaning that no air guiding mechanism 200 is provided at the air outlet 102, i.e., there is no air guide plate at the air outlet 102. The first air guide plate 210 is located within the main air duct 110, and is spaced apart from the air outlet 102, so that the movement of the first air guide plate 210 is not visible from the outside. This is equivalent to the minimum distance between the rotation axis of the first air guide plate 210 and the air outlet 102 being greater than the width of the first air guide plate 210. This arrangement ensures that the first air guide plate 210 is kept at a certain distance from the air outlet 102. When the first air guide plate 210 rotates within the main air duct 110, the rotation of the first air guide plate 210 is not easily observed from outside the air outlet 102, thus avoiding the visual impact caused by the rotation of the first air guide plate 210 and improving the visual comfort of the wall-mounted air-conditioned room.

[0056] Please see Figures 1 to 3 In one embodiment, the auxiliary air duct 120 is arranged in a downward-curving arc shape along its air outlet direction. It is understood that the arc-shaped auxiliary air duct 120 helps to improve the smoothness of airflow, and the downward curvature of the auxiliary air duct 120 helps to guide hot air towards the ground, making it easier for the hot air to reach the ground and form a floor heating airflow, thereby improving the comfort of the user experience.

[0057] Please see Figures 3 to 5In one embodiment, the wall-mounted air conditioner further includes a fan wheel 160 installed within the housing 100; the auxiliary air duct 120 has an upper air duct wall 123 and a lower air duct wall 124 disposed opposite to each other, and the ratio of the diameter of the circle containing the lower air duct wall 124 to the diameter of the fan wheel 160 is in the range of [0.5, 0.7]. It is understood that, for ease of explanation, the diameter of the fan wheel 160 is now defined as D1, the diameter of the circle containing the lower air duct wall 124 is defined as D2, and the ratio of D2 to D1 is in the range of [0.5, 0.7]. Figure 4 As shown. This setting effectively limits the size of the downdraft duct wall 124. If the ratio of D2 to D1 is too small, the downward curvature of the auxiliary air outlet 122 of the downdraft duct wall 124 will be too small, preventing hot air from blowing directly to the ground and affecting the direction of hot air output, which is not conducive to forming a floor heating airflow. If the ratio of D2 to D1 is too large, the width of the auxiliary air duct 120 will be too small, which is not conducive to the flow of hot air. Therefore, by limiting the ratio of the diameter of the circle containing the downdraft duct wall 124 to the diameter of the impeller 160 to [0.5, 0.7], hot air can be smoothly blown to the ground along the auxiliary air duct 120, which is beneficial to improving the comfort of the user experience. The ratio of D2 to D1 can be 0.5, 0.6, or 0.7, and is not specifically limited here.

[0058] In one embodiment, the ratio of the diameter of the circle containing the upper air duct wall 123 to the diameter of the impeller 160 ranges from [0.8, 1.2]. It can be understood that the diameter of the circle containing the upper air duct wall 123 is D3, and the ratio of D3 to D1 ranges from [0.8, 1.2]. This arrangement ensures the width of the auxiliary air duct 120 and ensures that hot air can be smoothly blown towards the ground, thereby improving the practicality of the wall-mounted air conditioner. The ratio of D3 to D1 can be 0.8, 1.0, or 1.2; no specific limitation is made here.

[0059] Please see Figure 3 and Figure 5 In one embodiment, the end of the lower air duct wall 124 away from the air outlet 102 is connected to the rotation axis of the second air guide plate 220. The minimum distance between the rotation axis of the second air guide plate 220 and the impeller 160 is L1, and the ratio of L1 to D1 ranges from [0.3, 0.5]. It can be understood that by limiting the ratio of L1 to D1, the position of the auxiliary air inlet 121 is effectively limited. The ratio of L1 to D1 can be 0.3, 0.4, or 0.5. This setting ensures that hot air can smoothly enter the auxiliary air duct 120, which is beneficial to the flow of hot air.

[0060] In one embodiment, the minimum distance between the upper air duct wall 123 and the impeller 160 is L2, and the ratio of L2 to D1 ranges from [0.12, 0.2]. It can be understood that by limiting the range of the ratio of L2 to D1, the position of the auxiliary air duct 120 is effectively limited, thereby allowing the position of the auxiliary air duct 120 to be set at the position of the impeller 160, resulting in a compact spatial arrangement within the housing 100 and improving the space utilization rate within the housing 100. The ratio of L2 to D1 can be 0.12, 0.16, or 0.2; no specific limitation is made here.

[0061] In one embodiment, the width of the first air guide plate 210 is L3, and the ratio of L3 to D1 ranges from [0.4, 0.6]. This setting effectively limits the width of the first air guide plate 210 according to the size of the impeller 160, making the first air guide plate 210 suitable for use within the air duct. This helps reduce material usage while still achieving the function of the first air guide plate 210, thereby saving material costs.

[0062] In heating mode, the first air guide plate 210 and the second air guide plate 220 are joined together, forming an angle between them. The angle ranges from [135° to 155°]. It can be understood that when the first air guide plate 210 and the second air guide plate 220 are joined, an angle α is formed, and the value of angle α is limited to [135° to 155°]. This arrangement allows the airflow in the main air duct 110 to smoothly enter the auxiliary air inlet 121, thereby improving the smoothness of airflow. The value of angle α can be 135°, 145°, or 155°; the specific value is not limited here.

[0063] In one embodiment, the width of the auxiliary air inlet 121 of the auxiliary air duct 120 is the same as the width of the auxiliary air outlet 122; and / or, the width of the second air guide plate 220 is the same as the width of the auxiliary air inlet 121. It is understood that having the width of the auxiliary air inlet 121 the same as the width of the auxiliary air outlet 122 ensures smooth airflow along the auxiliary air duct 120. Having the width of the second air guide plate 220 the same as the width of the auxiliary air inlet 121 ensures that the second air guide plate 220 can close the auxiliary air inlet 121, thereby improving the reliability of the wall-mounted air conditioner.
