[0059] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0060] The following is for reference. Figures 1-21 A duct assembly 100 according to an embodiment of the first aspect of the present invention is described.

[0061] like Figures 5-13 As shown, the air duct assembly 100 according to a first aspect embodiment of the present invention includes: an air duct plate 10 and an end volute tongue 20.

[0062] Specifically, the duct plate 10 is vertically arranged and forms an air outlet 11 through the duct plate 10. The duct plate 10 includes a volute tongue body 12 and a mounting base 13. The volute tongue body 12 extends vertically and is located on one side edge of the air outlet 11. The mounting base 13 is connected to the volute tongue body 12 and is located on the upper and / or lower side of the volute tongue body 12. That is, the mounting base 13 can be located on the upper side of the volute tongue body 12, the lower side of the volute tongue body 12, or both the upper and lower sides of the volute tongue body 12. The end volute tongue 20 is vertically arranged and is detachably connected to the mounting base 13.

[0063] The air duct plate 10 guides the airflow blown by the air outlet 11, and different structures of the air duct plate 10 can achieve different air guiding effects.

[0064] In the design and production of air conditioner 1000, the duct component 100 is designed as a platform, and one platform of duct component 100 can be applied to different models of air conditioner 1000, thereby reducing development time and development costs. In air conditioner 1000, when the structure of the components that connect to the duct component 100 in the upstream and downstream directions of airflow is modified, the airflow trajectory towards the duct plate 10 will change, and the airflow trajectory blown out from the duct plate 10 will also change. As a result, abnormal noise may be caused in the duct, thus affecting the quiet performance of air conditioner 1000. At this time, if the entire duct plate 10 is modified, it may affect the quality of air conditioners 1000 that are already in mass production, requiring synchronous verification of air conditioners 1000 that are already in mass production, which will consume a lot of time and costs.

[0065] In this embodiment, a mounting base 13 is provided on the air duct plate 10. Since the end volute tongue 20 is detachably connected to the mounting base 13, end volute tongues 20 with different structures can be installed on the mounting base 13. The end volute tongues 20 with different structures and the volute tongue main board can be combined to form air duct plates 10 with different structures. Thus, when the airflow blows through the air duct plates 10 with different structures, the airflow will produce different flow states at the end of the air duct plate 10. Through experimental verification, a suitable end volute tongue 20 can be found so that there is no abnormal noise when the airflow blows through the air duct. In this way, the air duct plate 10 can be matched with the new model of air conditioner 1000, and the entire structure of the air duct plate 10 is not redesigned.

[0066] According to the first aspect of the present invention, the air duct assembly 100 is detachably connected to the mounting base 13 via the end volute tongue 20, enabling the replacement of the end volute tongue 20 with different structures on the mounting base 13. Different structures of air duct plates 10 are formed by combining different end volute tongues 20 and volute tongue bodies 12, so that the air duct plates 10 can achieve different air guiding effects. Thus, the air duct assembly 100 can be adapted to different models of air conditioners 1000. At the same time, the entire air duct plate 10 does not need to be redesigned or verified, avoiding any impact on the quality and stability of existing air conditioner models 1000 and reducing the development cost of new air conditioner models 1000.

[0067] In some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, the end volute 20 is connected to the mounting base 13 via fastener 30. The fastener 30 connection is convenient and stable. Connecting the end volute 20 and the mounting base 13 via fastener 30 can improve production efficiency and enhance the reliability of the air conditioner 1000.

[0068] In some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, the end of the volute tongue 20 is located away from the end of the air outlet 11 in the horizontal plane (e.g., Figure 9 The end volute 20 shown has a fixing plate 21 at its front end. A first fixing hole 211 is formed on the fixing plate 21, and a second fixing hole 131 is formed on the mounting base 13. Fasteners 30 are inserted into the first fixing hole 211 and the second fixing hole 131. This improves the connection strength between the end volute 20 and the mounting base 13, and also allows for positioning of the connection between the end volute 20 and the mounting base 13.

[0069] In some embodiments of the present invention, the fastener 30 is a screw. Screws are low-cost, and production costs can be reduced by setting the fastener 30 as a screw.

[0070] In some embodiments of the present invention, such as Figure 10 As shown, a limiting groove 132 is formed on one of the mounting base 13 and the end volute 20, and a limiting protrusion 22 is formed on the other. The limiting protrusion 22 is fitted into the limiting groove 132. That is, the limiting groove 132 can be formed on the mounting base 13 and the limiting protrusion 22 can be formed on the end volute 20, or the limiting protrusion 22 can be formed on the mounting base 13 and the limiting groove 132 can be formed on the end volute 20.

[0071] In this embodiment, preferably, a limiting groove 132 is formed on the mounting base 13, and a limiting protrusion 22 is formed on the end volute 20. The limiting protrusion 22, which cooperates with the limiting groove 132, can limit the displacement of the end volute 20 relative to the mounting base 13. At the same time, when the end volute 20 and the mounting base 13 are assembled, the limiting protrusion 22, which cooperates with the limiting groove 132, can also play a positioning role.

[0072] In some embodiments of the present invention, such as Figure 12 and Figure 13 As shown, the mounting base 13 includes a main body 133 and a stop portion 134, wherein the stop portion 134 is connected to the main body 133 and is located on the side of the main body 133 facing the air vent 11 (e.g., Figure 13 (As shown in the diagram, on the rear side of the main seat 133), a stop portion 134 and the main seat 133 cooperate to define a limiting groove 132. The opening direction of the limiting groove 132 is opposite to the airflow direction of the vent 11. A limiting protrusion 22 is formed at the other end of the end tongue 20 facing the stop portion 134. The airflow from the vent 11 will blow over the stop portion 134. By making the opening direction of the limiting groove 132 opposite to the airflow direction of the vent 11, the probability of the airflow blowing over the vent 11 entering the limiting groove 132 is reduced. This reduces the probability of air leakage and abnormal noise in the limiting groove 132.

[0073] During assembly, the limiting protrusion 22 at the other end of the end volute 20 is inserted into the limiting groove 132 on the mounting base 13. When assembled, the end volute 20 abuts against the main body 133, and the position where the end volute 20 abuts against the mounting base 13 forms a "V" shape. Since one end of the end volute 20 is connected to the mounting base 13 via the fastener 30, when the other end of the end volute 20 is displaced from the limiting groove 132, the limiting protrusion 22 at the other end of the end volute 20 will be abutted against by the inner wall of the stop part 134, thereby preventing the limiting protrusion 22 from falling out of the limiting groove 132. Thus, the end volute 20 is fixedly connected to the mounting base 13.

[0074] In some embodiments of the present invention, the fitting clearance between the limiting protrusion 22 and the sidewall of the limiting groove 132 is less than or equal to 0.2 mm. This further reduces the probability of airflow entering the limiting groove 132, thereby further reducing the probability of air leakage and abnormal noise generation in the limiting groove 132.

[0075] In some embodiments of the present invention, such as Figure 10As shown, the side surface of the stop portion 134 facing the air vent 11 is the first surface 1341, and the side surface of the other end of the end volute 20 facing the air vent 11 is the second surface 23. In the width direction of the air vent 11, the height difference between the edge of the first surface 1341 facing the second surface 23 and the edge of the second surface 23 facing the first surface 1341 is less than or equal to 0.2 mm. Therefore, when the airflow blows from the first surface 1341 to the second surface 23, the obstruction caused by the height difference between the first surface 1341 and the second surface 23 to the airflow does not affect the normal use of the air conditioner 1000.

[0076] In some embodiments of the present invention, such as Figures 16-20 As shown, the end volute 20 includes a first tongue plate 24 and a second tongue plate 25, both of which extend vertically. In the horizontal projection plane, one end of the first tongue plate 24 is connected to one end of the second tongue plate 25 by an arc, and the first tongue plate 24 and the second tongue plate 25 are arranged at an angle. Preferably, the airflow blows from the first tongue plate 24 to the second tongue plate 25. By adjusting the arc of the connecting arc between the first tongue plate 24 and the second tongue plate 25 and the angle between the first tongue plate 24 and the second tongue plate 25, the end volute 20 can form different structures. For example, the first tongue plate 24 and the second tongue plate 25 can be formed into rounded corners, or they can be formed into cones. Thus, the end volute 20 can achieve different air guiding effects, thereby allowing the end volute 20 to be adapted to different models of air conditioners 1000.

[0077] The mounting base 13 is at least partially located between the first tongue plate 24 and the second tongue plate 25. Furthermore, the limiting protrusion 22 is provided at the end of the first tongue plate 24, and the fixing plate 21 is provided at the end of the second tongue plate 25. This allows the relative positions of the limiting protrusion 22 and the fixing plate 21 to be kept consistent, thereby enabling the end worm tongues 20 with different structures to meet the assembly requirements on the mounting base 13.

[0078] In some embodiments of the present invention, such as Figure 14 and Figure 15 As shown, the surface of the end volute 20 facing away from the mounting base 13 is provided with a groove 26. The groove 26 extends from one end of the end volute 20 in the horizontal direction to the other end. There are multiple grooves 26, which are arranged at intervals in the vertical direction. For example, there can be three, four or five grooves 26. When abnormal noise in the air duct is transmitted to the groove 26, the groove 26 can absorb part of the vibration wave of the abnormal noise, thereby achieving the effect of noise reduction.

[0079] In some embodiments of the present invention, such as Figure 20 and Figure 21As shown, the end volute 20 further includes a third tongue plate 27. The third tongue plate 27 is vertically arranged and connected to the end of the second tongue plate 25 away from the first tongue plate 24. In the horizontal plane, one end of the third tongue plate 27 is tangent to the second tongue plate 25, and the other end of the third tongue plate 27 extends along an arc away from the first tongue plate 24. Thus, the first tongue plate 24, the second tongue plate 25, and the third tongue plate 27 are formed in a spoon shape. The airflow flows from the first tongue plate 24 to the second tongue plate 25 and then to the third tongue plate 27. By adjusting the relative angle of the first tongue plate 24, the second tongue plate 25, and the third tongue plate 27, the flow direction of the airflow on the surfaces of the first tongue plate 24, the second tongue plate 25, and the third tongue plate 27 can be changed, thereby achieving different air guiding effects and enabling the end volute 20 to be adapted to different models of air conditioners 1000.

[0080] In some embodiments of the present invention, such as Figure 8 and Figure 11 As shown, there are two air vents 11, namely the first air vent 111 and the second air vent 112, which are arranged alternately on the left and right sides. There are two volute tongue bodies 12, namely the first volute tongue 12a and the second volute tongue 12b, wherein the first volute tongue 12a is located on the edge of the first air vent 111 facing away from the second air vent 112 (e.g., Figure 8 The first air vent 111 shown is located on the left edge of the first air vent 111, and the first volute tongue 12a has end volute tongues 20 on both its upper and lower sides. The second volute tongue 12b is located on the side edge of the second air vent 112 that is away from the first air vent 111 (e.g., the left edge of the first air vent 111). Figure 8 The second air vent 112 shown in the figure has a right edge, and the upper and lower sides of the second volute tongue 12b are provided with end volute tongues 20.

[0081] In this way, the air outlet 11 is provided with end volutes 20 at the four corners of the vertical projection of the airflow direction. When the component structure of the air outlet 11 in the upstream and downstream directions changes and causes abnormal noise in the airflow in the duct, the airflow direction at the four corners of the air outlet 11 can be changed by replacing the end volutes 20 with different structures, thereby eliminating the abnormal noise in the airflow in the duct.

[0082] In some embodiments of the present invention, such as Figures 2-4 As shown, the air duct assembly 100 also includes two impellers 40, which are respectively located at the first air outlet 111 and the second air outlet 112. By setting the impellers 40, the impellers 40 can generate airflow in the air duct, thereby enabling the air conditioner 1000 to work normally. By setting two impellers 40, which correspond one-to-one with the two air outlets 11, the air volume of the air conditioner 1000 can be increased, making the airflow of the air conditioner 1000 more uniform, thereby improving the effect of the air conditioner 1000.

[0083] In some embodiments of the present invention, such as Figures 2-4 As shown, the air duct assembly 100 also includes: a fan wheel 40 partition, which is located between the two fan wheels 40. By setting the fan wheel 40 partition, the interference between the airflows blown out from the two fan wheels 40 can be reduced, thereby reducing the probability of abnormal noise from the airflow. At the same time, it further ensures the uniformity of the airflow from the air conditioner 1000 and improves the performance of the air conditioner 1000.

[0084] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the air duct assembly 100 also includes a motor 60, which is located at the end of the impeller 40. There are two motors 60, one for each impeller 40, and they are electrically connected. By setting the motors 60, the motors 60 can drive the impeller 40 to rotate, thereby generating airflow in the air duct.

[0085] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the air duct assembly 100 also includes: a motor 60 cover plate. There are two motor 60 covers, and each motor 60 cover corresponds to a motor 60. The motor 60 cover plate is located on the outside of the motor 60. By setting the motor 60 cover plate, the motor 60 cover plate can cover the motor 60, thereby protecting the motor 60 from external interference.

[0086] An air conditioner 1000 according to a second aspect of the present invention includes the air duct assembly 100 described above according to a first aspect of the present invention.

[0087] According to the second aspect of the present invention, the air conditioner 1000, by providing the air duct assembly 100 of the first aspect of the present invention, wherein the end volute tongue 20 is detachably connected to the mounting base 13, allows for the replacement of end volute tongues 20 with different structures on the mounting base 13. By combining different end volute tongues 20 and volute tongue bodies 12, air duct plates 10 with different structures are formed, enabling the air duct plates 10 to achieve different air guiding effects. Thus, the air duct assembly 100 can be adapted to different models of air conditioners 1000. At the same time, the entire air duct plate 10 is not redesigned or verified, avoiding any impact on the quality and stability of existing air conditioner models 1000 and reducing the development cost of new air conditioner models 1000.

[0088] In some embodiments of the present invention, such as Figures 2-4 As shown, the air conditioner 1000 also includes an evaporator assembly 200, which is connected to the air duct assembly 100 and located upstream of the air duct assembly 100 in the airflow direction (e.g., Figure 2(The air duct assembly 100 shown is located in the rear direction). By setting the evaporator assembly 200, the airflow flowing through the evaporator assembly 200 is heat-exchanged to reach the set temperature. Then, the air duct assembly 100 blows out the heat-exchanged airflow, thereby realizing the temperature regulation function of the air conditioner 1000.

[0089] In some embodiments of the present invention, such as Figure 2 As shown, the air conditioner 1000 also includes: a rear box assembly 300, which is connected to the evaporator assembly 200 and located upstream of the evaporator assembly 200 in the airflow direction (e.g., Figure 2 (As shown in the diagram, the evaporator assembly 200 is positioned at its rear side). The rear housing assembly 300 has an air inlet 310, which is directly opposite the evaporator assembly 200. Airflow enters the air conditioner 1000 through the air inlet 310, and the evaporator assembly 200 exchanges heat with the incoming airflow. By providing the rear housing assembly 300, the internal components of the air conditioner 1000 can be shielded, preventing external interference and making the air conditioner 1000 look more aesthetically pleasing.

[0090] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the air conditioner 1000 also includes: an air outlet frame assembly 400, which is connected to the air duct component and located downstream of the air duct assembly 100 in the airflow direction (e.g., Figure 2 (The air duct assembly 100 shown is in the front direction). By setting the air outlet frame assembly 400, the air outlet frame assembly 400 can limit the direction of air duct extension and the cross-sectional area of ​​the air duct when air is discharged, so that the air conditioner 1000 can achieve the set blowing effect.

After the airflow inside the air conditioner 1000 flows through the air outlet frame assembly 400, it is blown out from the air outlet 510. By setting the panel assembly 500, the panel assembly 500 can shield the components inside the air conditioner 1000, so that the components inside the air conditioner 1000 are not disturbed by the outside. At the same time, the panel assembly 500 also provides space for the air outlet 510 and the air conditioner 1000 operation panel.

[0092] In some embodiments of the present invention, such as Figure 2As shown, the air conditioner 1000 also includes a top cover 600 and a chassis 700, wherein the top cover 600 is located at the top of the air conditioner 1000 and the chassis 700 is located at the bottom of the air conditioner 1000. By providing the top cover 600, the top of the air conditioner 1000 can be covered, preventing the components at the top of the air conditioner 1000 from being disturbed by the outside world. Similarly, by providing the chassis 700, the bottom of the air conditioner 1000 can be covered, preventing the components at the bottom of the air conditioner 1000 from being disturbed by the outside world. The chassis 700 can also support the air conditioner 1000, making the air conditioner 1000 more stable.
