[0036] The following is for reference. Figures 1-6 This invention describes an air conditioner 1000 according to an embodiment of the present invention.

[0037] like Figure 1 As shown, Figure 1 The arrows indicate the airflow direction. According to this utility model, the air conditioner 1000 includes: a casing 2, a heat exchange structure 4, and a water collection plate assembly 1. An air duct 7 is formed inside the casing 2, and an air inlet 5 and an air outlet 6, respectively connected to the air duct 7, are formed on the casing 2. The heat exchange structure 4 is disposed within the air duct 7. The water collection plate assembly 1 is disposed within the air duct 7 and located between the air inlet 5 and the heat exchange structure 4. The water collection plate assembly 1 is suitable for collecting condensate from the surface of the heat exchange structure 4. The water collection plate assembly 1 includes a first guide plate 20 and a second guide plate 30. The second guide plate 30 is connected to the first guide plate 20, and the first guide plate 20 and / or the second guide plate 30 form a water guide groove 20a suitable for guiding the flow of condensate. Figure 4 As shown, Figure 4 The arrow in the diagram indicates the direction of airflow. The second guide plate 30 is located upstream of the first guide plate 20 in the direction of airflow, and at least one side of its surface in the thickness direction is constructed as an arc-shaped surface.

[0038] Specifically, a fan 3 is generally installed inside the casing 2. The fan 3 operates to drive airflow. Under the action of the fan 3, the airflow enters the air duct 7 inside the casing 2 through the air inlet 5, and exchanges heat with the heat exchange structure 4 through the inlet side of the heat exchange structure 4. The airflow after heat exchange flows out through the outlet side of the heat exchange structure 4 to the air duct 7, and then is blown out of the air conditioner 1000 through the air outlet 6 of the casing 2. Here, since water vapor will condense on the surface of the heat exchange structure 4 during use, condensate will be generated. Therefore, a water receiving plate assembly 1 is provided to collect the condensate on the surface of the heat exchange structure 4 and guide the condensate to flow out of the air conditioner 1000. The first guide plate 20 and the second guide plate 30 can guide the airflow inside the casing 2 towards the inlet side of the heat exchange structure 4, while the water guide groove 20a formed on the first guide plate 20 and / or the second guide plate 30 can guide the condensate to be discharged from the air conditioner 1000.

[0039] Here you can refer to Figure 2 and Figure 3 Both the first guide plate 20 and the second guide plate 30 extend along the length direction, and the first guide plate 20 can be connected to the second guide plate 30 in the width direction. Compared to the first guide plate 20, the second guide plate 30 is located upstream in the airflow direction. Figure 3 The arrow in the image indicates the direction of airflow. The second guide plate 30 can guide the air drawn in by the negative pressure of the fan 3 to flow along the arc surface, creating a wall-attached deflection flow, reducing resistance, and directing the airflow to the direction of the first guide plate 20. The first guide plate 20 then continues to guide the airflow to the inlet side of the heat exchange structure 4. The design of the second guide plate 30 can avoid significant flow separation caused by setting the water receiving plate assembly 1 on the inlet side of the heat exchange structure 4, thereby avoiding vortex areas and noise caused by flow separation.

[0040] like Figure 5 and Figure 6 As shown, when the airflow flows, it passes over the two surfaces of the first guide plate 20 and the second guide plate 30 in the thickness direction. Since the second guide plate 30 is located upstream of the airflow direction, to avoid the second guide plate 30 obstructing the airflow, at least one surface of the second guide plate 30 in the thickness direction is designed as an arc surface. The principle of wall-following flow caused by the Coanda effect can be used to guide the airflow to flow along the surfaces of the first guide plate 20 and the second guide plate 30, thereby avoiding a reduction in airflow velocity and reducing the occurrence of flow separation or vortex phenomena. This eliminates the broadband aerodynamic noise caused by pressure pulsation due to the regular generation and disruption of vortex zones, achieving noise reduction. The noise level generated by the water receiving plate assembly 1 designed according to this utility model is 65dB. The airflow flows through the water receiving plate assembly 1 to the heat exchange structure 4, and then is blown out by the heat exchange structure 4, allowing it to be blown into the room at a more uniform speed, improving the thermal comfort experience of the human body.

[0041] According to the present invention, the air conditioner 1000 has a water receiving plate assembly 1 provided with a first guide plate 20 and a second guide plate 30. During the flow of air, the air can come into contact with the second guide plate 30 and the first guide plate 20 in sequence. By designing an arc-shaped surface on the second guide plate 30 located upstream of the airflow direction, the airflow can be guided to flow along the arc-shaped surface when the second guide plate 30 comes into contact with the airflow, so as to avoid the second guide plate 30 from obstructing the airflow, thereby avoiding the reduction of airflow velocity and preventing flow separation. Noise reduction can also be achieved by reducing eddy current phenomenon.

[0042] Furthermore, the water guiding channel 20a can be disposed on the first guide plate 20, or on the second guide plate 30, or both the first guide plate 20 and the second guide plate 30 can have water guiding channels 20a formed on them. Moreover, the shape of the water guiding channel 20a can be an arc-shaped channel, a rectangular channel, or any other arbitrary shape.

[0043] In some embodiments, the water receiving plate assembly 1 further includes a drainage connector 40, which has a drainage ditch that communicates with the water guide trough 20a. The drainage ditch is connected to the water guide trough 20a and the drain outlet of the air conditioner 1000, respectively, so as to discharge the condensate in the water guide trough 20a into the air conditioner 1000.

[0044] In some embodiments, a water collection tray is also provided inside the casing 2 of the air conditioner 1000. The water collection tray is connected to the drainage groove of the drainage connector 40 and is also connected to the drain outlet of the air conditioner 1000. The condensate flowing into the water collection tray can be discharged from the air conditioner 1000 through the drain outlet of the air conditioner 1000.

[0045] Furthermore, a water receiving plate assembly 1 designed according to this utility model can also be provided on the outlet side of the heat exchange structure 4. The water receiving plate assembly 1 can guide the airflow direction while receiving condensate, and will not cause negative interference to the airflow velocity.

[0046] In some embodiments, the heat exchange structure 4 is an evaporator. Figure 1 In the embodiment shown, since the evaporator is tilted toward the air inlet 5, the water receiving plate assembly 1 can be placed between the evaporator and the air inlet 5 so that the water receiving plate assembly 1 can receive the condensate flowing downward along the surface of the evaporator under the action of gravity.

[0047] According to some embodiments of this utility model, such as Figure 4 As shown ( Figure 4 The thickness direction of the first guide plate 20 is different from that of the second guide plate 30 (as indicated separately). The second guide plate 30 is bent towards the top side in the thickness direction, and its two side surfaces in the thickness direction are respectively constructed as a first arc-shaped surface 31 and a second arc-shaped surface 32. Specifically, the airflow generally flows from the bottom of the water receiving plate assembly 1 towards the top of the water receiving plate assembly 1, and from the direction of the second guide plate 30 towards the direction of the first guide plate 20. Therefore, the second guide plate 30 is designed to be bent towards the top side in the thickness direction. At this time, both side surfaces of the second guide plate 30 in the thickness direction can be constructed as arc-shaped surfaces, with the top surface in the thickness direction being the first arc-shaped surface 31 and the bottom surface in the thickness direction being the second arc-shaped surface 32. This allows the airflow to be guided on both sides of the second guide plate 30 in the thickness direction, further reducing the influence of the second guide plate 30 on the airflow velocity, while avoiding the obstruction of the airflow direction by the structure of the second guide plate 30, reducing the occurrence of flow separation or vortex phenomena, and achieving noise reduction.

[0048] It is worth mentioning that the airflow direction mentioned in the above embodiments is not used to limit the actual airflow direction inside the air conditioner 1000. The setting position of the water receiving plate assembly 1 can be adjusted according to the actual airflow direction inside the air conditioner 1000, and the tilt direction of the first guide plate 20 and the second guide plate 30 can also be adjusted.

[0049] According to some embodiments of this utility model, such as Figure 4 As shown ( Figure 4 The width direction of the first guide plate 20 is different from that of the second guide plate 30 (as indicated separately). The first connecting end 21 of the first guide plate 20 in the width direction is connected to the second connecting end 33 of the second guide plate 30 in the width direction, and a portion of the top surface of the first guide plate 20 in the thickness direction is recessed to form a water guide groove 20a. Specifically, both the first guide plate 20 and the second guide plate 30 extend along the length direction, with one end of the first guide plate 20 in the width direction being the first connecting end 21 and the other end of the second guide plate 30 in the width direction being the second connecting end 33. The first connecting end 21 and the second connecting end 33 are connected. The water guide groove 20a is located on the top surface of the first guide plate 20 in the thickness direction, and a portion of the top surface of the first guide plate 20 in the thickness direction is recessed to form the water guide groove 20a, which extends along the length direction of the first guide plate 20. The water guide groove 20a is designed on the top surface of the first guide plate 20 to ensure the integrity of the arc-shaped surface of the second guide plate 30 and to ensure the function of the arc-shaped surface in guiding the airflow.

[0050] In some embodiments, one end of the second guide plate 30 is a second connecting end 33 in the width direction and the other end is a free end 34. The first arc-shaped surface 31 and the second arc-shaped surface 32 of the second guide plate 30 are connected by an arc at the free end 34 to guide the airflow.

[0051] According to some embodiments of this utility model, such as Figure 4 As shown, the first guide plate 20 also has a protrusion 22, which protrudes towards the top side in the thickness direction and is connected to the first connecting end 21 in the width direction. The top surface of the first connecting end 21 in the thickness direction is recessed. The protrusion 22, the first connecting end 21, and the second connecting end 33 together define the water guide groove 20a. In some embodiments, the first guide plate 20 has a first connecting end 21, a protrusion 22, and a third connecting end 23 connected in sequence. The first connecting end 21 is located upstream in the airflow direction. The first connecting end 21 is designed with a recessed top surface in the thickness direction, so that a thickness difference is formed between the first connecting end 21, the protrusion 22, and the second connecting end 33 of the second guide plate 30. This allows the protrusion 22, the first connecting end 21, and the second connecting end 33 of the second guide plate 30 to jointly define the water guide groove 20a. At this time, the water guide groove 20a is located at the part where the first guide plate 20 and the second guide plate 30 are connected.

[0052] According to some embodiments of this utility model, such as Figure 4 As shown, the top surface of the protrusion 22 in the thickness direction is constructed as a third arc-shaped surface 221. The third arc-shaped surface 221 is bent towards the top side in the thickness direction to guide the airflow along the surface of the first guide plate 20. It can work together with the second guide plate 30 to guide the airflow direction and avoid reducing the airflow velocity. This can reduce the occurrence of flow separation or vortex phenomena and further achieve the effect of noise reduction.

[0053] According to some embodiments of this utility model, such as Figure 4 As shown, the bottom surface of the first connecting end 21 protrudes towards the bottom side in the thickness direction to form a protrusion 211. Here, in order to form the water guide channel 20a, the thickness of the first connecting end 21 is smaller than that of the protrusion 22 and the second connecting end 33. Since the first connecting end 21 connects the protrusion 22 and the second connecting end 33, the first connecting end 21 needs to have sufficient structural strength. The bottom surface of the first connecting end 21 in the thickness direction can be designed to protrude towards the bottom side to form the protrusion 211. This ensures that the first connecting end 21 has sufficient structural strength while increasing the capacity of the water guide channel 20a, ensuring the connection stability of the first guide plate 20 and the second guide plate 30, and thus ensuring the service life of the water receiving plate assembly 1.

[0054] According to some embodiments of this utility model, such as Figure 4 As shown, the protrusion 211 is connected to the bottom surface of the second guide plate 30 in the thickness direction. At this time, the airflow flowing from the second arc surface 32 of the second guide plate 30 toward the protrusion 211 can pass smoothly, which can avoid the protrusion 211 from obstructing the airflow and reduce the influence of the protrusion 211 on the airflow velocity.

[0055] In some embodiments, such as Figure 4 As shown, the bottom surface of the first guide plate 20 in the thickness direction is a plane. Furthermore, the bottom surface of the first guide plate 20 in the thickness direction is transitionally connected to the protrusion 211.

[0056] According to some embodiments of this utility model, such as Figure 4 As shown, the end of the first guide plate 20 furthest from the second guide plate 30 is the third connecting end 23, and the thickness of the third connecting end 23 gradually decreases in the direction away from the second guide plate 30. Here, the third connecting end 23 is located downstream of the airflow direction and adjacent to the inlet side of the heat exchange structure 4. The gradual decrease in thickness of the third connecting end 23 in the direction away from the second guide plate 30 guides the airflow on both sides of the thickness direction of the first guide plate 20 to converge and flow towards the inlet side of the heat exchange structure 4.

[0057] According to some embodiments of this utility model, such as Figure 2As shown, the water receiving plate assembly 1 also includes an outer frame 10, which is connected to the first guide plate 20 and the second guide plate 30. The first guide plate 20 and the second guide plate 30 are configured as multiple, one-to-one correspondences, with the multiple first guide plates 20 spaced apart along the extension direction of the outer frame 10, i.e., spaced apart along a first direction. The water guide channels 20a are also configured as multiple, spaced apart along the first direction. Here, the outer frame 10 of the water receiving plate assembly 1 can mate with the inner wall of the housing 2 to allow the entire water receiving plate assembly 1 to be installed on the inlet side of the heat exchange structure 4.

[0058] In some embodiments, a flow channel is formed inside the outer frame 10, which is connected to the water guide 20a and the drain outlet of the air conditioner 1000, respectively, so as to guide the condensate from the water guide 20a to the inner space of the outer frame 10 and discharge it into the air conditioner 1000.

[0059] In some embodiments, a water collection tray is also provided inside the casing 2 of the air conditioner 1000. The water collection tray is connected to the flow channel inside the outer frame 10 and is also connected to the drain outlet of the air conditioner 1000. The condensate flowing into the water collection tray can be discharged from the air conditioner 1000 through the drain outlet of the air conditioner 1000.

[0060] In some embodiments, such as Figure 2 As shown, the outer frame 10 includes a first frame portion 11 and a second frame portion 12. The first frame portion 11 and the second frame portion 12 are spaced apart in a second direction and both extend along a first direction. The first frame portion 11 and the second frame portion 12 both have the aforementioned flow channels inside. The first guide plate 20 and the second guide plate 30 both extend in a second direction. The two ends of the first guide plate 20 in the second direction are respectively connected to the first frame portion 11 and the second frame portion 12. The two ends of the second guide plate 30 in the second direction are respectively connected to the first frame portion 11 and the second frame portion 12. The second direction is consistent with the length direction of the first guide plate 20 and the second guide plate 30.

[0061] According to some embodiments of this utility model, such as Figure 1 As shown, the projection of the water receiving plate assembly 1 in the height direction coincides with at least a portion of the projection of the heat exchange structure 4 in the height direction. The water guiding groove 20a extends in the second direction and a plurality of water guiding grooves 20a are arranged at intervals along the first direction to cover at least a portion of the installation area of ​​the heat exchange structure 4, thereby receiving condensate on the surface of the heat exchange structure 4.

[0062] In some embodiments, such as Figure 2As shown, a connecting section 13 is provided between two adjacent first guide plates 20 to connect the two adjacent first guide plates 20 and ensure the overall structural strength of the water receiving plate assembly 1. Alternatively, a connecting section 13 is provided between two adjacent second guide plates 30 to connect the two adjacent second guide plates 30 and ensure the overall structural strength of the water receiving plate assembly 1. Alternatively, the first guide plate 20 and the corresponding second guide plate 30 can together form a water receiving plate. The number of water receiving plates is not limited, and two adjacent water receiving plates are connected by the connecting section 13.

[0063] Furthermore, the material of the water receiving plate is not limited to plastic, metal, rubber, ceramic, etc., and the length, width, bending angle, and other parameters of each arc-shaped surface can be designed according to actual needs.

[0064] In some embodiments, such as Figure 3 As shown, the dimensions of each water receiving plate in the width direction and / or thickness direction can be the same or different.

[0065] In some embodiments, such as Figure 2 Figure 2 As shown, the connecting segments 13 are configured as a plurality of segments spaced apart in the second direction.

[0066] In summary, according to the present invention, the air conditioner 1000 has a water receiving plate assembly 1 with a first guide plate 20 and a second guide plate 30. During the flow, the airflow can sequentially contact the second guide plate 30 and the first guide plate 20. By designing an arc-shaped surface on the second guide plate 30 located upstream of the airflow direction, the second guide plate 30 can guide the airflow to flow along the arc-shaped surface when it contacts the airflow. This avoids the second guide plate 30 from obstructing the airflow, thereby avoiding a reduction in airflow velocity and reducing the occurrence of flow separation or eddy current phenomena, thus achieving noise reduction.
