[0006] The embodiments of this utility model provide a technical solution: A duct assembly, comprising: An evaporator assembly, including an evaporator bracket and an evaporator mounted within the evaporator bracket; An axial flow air supply assembly includes a motor bracket, a motor, and axial flow fan blades. The motor bracket is connected to the front side of the evaporator bracket, and the motor is mounted on the motor bracket and connected to the axial flow fan blades.

[0007] The air duct assembly provided in this embodiment of the utility model has its motor bracket connected to the evaporator bracket, and the two form an integral structure, which makes the structure of the air duct assembly simpler, the assembly difficulty in the air conditioner cabinet lower, and can improve the compactness of the internal structure of the air conditioner cabinet.

[0008] In an optional embodiment, the evaporator includes a first portion and a second portion perpendicular to the horizontal plane, the first portion and the second portion being connected at an angle to form a V-shaped structure with an opening facing the axial flow air supply assembly.

[0009] The first part of the evaporator is connected to the second part at an angle to form a V-shaped structure, which can further improve the compactness of the internal structure of the air conditioner cabinet while also having a larger heat exchange area, significantly improving the heat exchange effect.

[0010] In an optional embodiment, the evaporator support includes an upper support, a side frame, and a water tray, wherein the upper support is connected to the top of the side frame, and the water tray is connected to the bottom of the side frame.

[0011] The motor bracket is connected to the upper bracket at its top and to the water receiving tray at its bottom, thus obtaining stable support from both the top and bottom and improving the overall stability of the air duct assembly.

[0012] In an optional embodiment, at least one of the upper bracket and the water receiving tray is integrally formed with the side frame.

[0013] At least one of the upper bracket and the water receiving tray is integrally formed with the side frame, which reduces the assembly difficulty of the air duct components and further improves the stability of the overall structure.

[0014] In an optional embodiment, the side frame surrounds the left and right ends of the evaporator.

[0016] In an optional embodiment, a first clearance groove is provided on the front side of the bottom wall of the upper bracket, and the rear side of the top of the motor bracket is embedded in the first clearance groove and connected to the upper bracket.

[0017] The rear top of the motor bracket is embedded in the first clearance groove opened on the front side of the upper bracket. On the one hand, this enables the motor bracket to be quickly positioned and connected on the evaporator bracket, improving the stability of the connection structure. On the other hand, it can reduce the space occupied by the air duct assembly in the front and rear directions, thereby further improving the compactness of the internal structure of the air conditioner cabinet.

[0018] In an optional embodiment, the air duct assembly further includes an air duct panel, the rear side of which is connected to the front side of the evaporator bracket, the motor bracket is located between the air duct panel and the evaporator bracket, the air duct panel is provided with an air duct through it, and the axial fan blades are located inside the air duct.

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a structural schematic of the air conditioner unit 10 provided in this embodiment. Figure 2 The diagram shown is an exploded view of the air conditioner unit 10.

[0030] The air conditioner unit 10 provided in this embodiment includes a front shell assembly 11, a rear cover assembly 12, a base 13, and an air duct assembly 100. The front shell assembly 11 and the rear cover assembly 12 are closed in the front-to-back direction to form an internal space. The base 13 is connected to the bottom end of the front shell assembly 11 and the rear cover assembly 12 and serves as a support. The air duct assembly 100 is disposed in the internal space formed by the front shell assembly 11 and the rear cover assembly 12.

[0031] Specifically, the rear cover assembly 12 has an air inlet, the front shell assembly 11 has an air outlet, and the air duct assembly 100 is located between the air inlet and the air outlet. In practical applications, when the air conditioner unit 10 is running, air can flow in from the air inlet on the rear cover assembly 12 under the action of the air duct assembly 100, pass through the air duct assembly 100, and be blown out from the air outlet on the front shell assembly 11.

[0032] Understandably, the rear cover assembly 12 is also equipped with a dustproof component covering the air inlet to prevent dust, insects, and other substances from entering the interior space. The air outlet of the front shell assembly 11 is also equipped with an air guide component to adjust the direction of airflow.

[0033] Please refer to the following: Figure 3 and Figure 4 , Figure 3 The diagram shown is a structural schematic of the air duct assembly 100. Figure 4 The image shown is a cross-sectional view of the air duct assembly 100.

[0034] The air duct assembly 100 provided in this embodiment includes an evaporator assembly 110, an axial flow air supply assembly 120, an air duct panel 130, and an air outlet grille 140. In order to simplify the structure, reduce the assembly difficulty of the air duct assembly 100, and improve the structural compactness of the air conditioning unit 10, in this embodiment, the evaporator assembly 110, the axial flow air supply assembly 120, the air duct panel 130, and the air outlet grille 140 are connected to form an integral structure.

[0035] Specifically, the axial flow air supply assembly 120 and the air duct panel 130 are both connected to the evaporator assembly 110, and the air outlet screen 140 is connected to the air duct panel 130. In the airflow direction from the air inlet to the air outlet, the evaporator assembly 110, the axial flow air supply assembly 120, the air duct panel 130 and the air outlet screen 140 are arranged in sequence.

[0036] Please refer to the following: Figure 5 , Figure 5 The diagram shows the connection structure between the axial flow air supply assembly 120 and the evaporator assembly 110.

[0037] In this embodiment, the evaporator assembly 110 includes an evaporator bracket 111 and an evaporator 112. The evaporator 112 is installed inside the evaporator bracket 111, and the axial flow air supply assembly 120 is connected to the front side of the evaporator bracket 111. The evaporator bracket 111 can be connected to at least one of the front shell assembly 11 and the rear cover assembly 12 to complete the assembly of the air duct assembly 100.

[0038] The axial flow air supply assembly 120 includes a motor bracket 121, a motor 122, and an axial flow fan blade 123. The motor bracket 121 is connected to the front side of the evaporator bracket 111, and the motor 122 is mounted on the motor bracket 121 and connected to the axial flow fan blade 123.

[0039] In this embodiment, the axial fan blade 123 is located on the side of the motor bracket 121 away from the evaporator bracket 111, that is, on the front side of the motor bracket 121.

[0040] When the air conditioner unit 10 is running, the motor 122 drives the axial fan blade 123 to rotate, drawing in ambient air through the air inlet on the rear cover assembly 12. The air exchanges heat with the evaporator 112 as it flows through it, and then passes through the axial fan blade 123, the air duct panel 130 and the air outlet cover 140 in sequence, and finally flows out through the air outlet on the front shell assembly 11.

[0041] In this embodiment, the evaporator 112 includes a first part 1121 and a second part 1122 perpendicular to the horizontal plane. The first part 1121 and the second part 1122 are connected at an angle to form a V-shaped structure with the opening facing the front side of the evaporator support 111.

[0042] In fact, the first part 1121 and the second part 1122 of the evaporator 112 are arranged in the left-right direction, and the planes on which the first part 1121 and the second part 1122 are located are at an angle to the front-back direction. Because the first part 1121 and the second part 1122 of the evaporator 112 are at an angle, they can obtain a larger airflow contact area with the limited internal space of the evaporator bracket 111, resulting in higher heat exchange efficiency and better heat exchange effect for the flowing air, which can significantly improve the temperature regulation performance of the air conditioning unit 10.

[0043] Preferably, in this embodiment, the included angle formed by the first part 1121 and the second part 1122 is greater than 90° and less than 180°.

[0044] In this embodiment, the evaporator support 111 includes an upper support 1111, a side frame 1112, and a water receiving tray 1113. The upper support 1111 is connected to the top of the side frame 1112, and the water receiving tray 1113 is connected to the bottom of the side frame 1112.

[0045] The upper bracket 1111, the side frame 1112, and the water tray 1113 together form an installation space with the opening facing forward. The evaporator 112 is installed in this installation space. The side frame 1112 has a hollow structure, and the installation space is in fluid communication with the air inlet on the rear cover assembly 12 through the hollow structure.

[0046] In this embodiment, the left and right ends of the evaporator 112 are enclosed by the side frame 1112. In other words, the end of the first part 1121 away from the second part 1122, and the end of the second part 1122 away from the first part 1121, are both enclosed by the side frame 1112. Specifically, in the left-right direction, the left and right ends of the evaporator 112 are located between the left and right sides of the side frame 1112; and the left and right sides of the side frame 1112 both protrude forward from the left and right ends of the evaporator 112.

[0047] Understandably, in practical applications, the left and right ends of the evaporator 112 are used to connect refrigerant pipes. The left and right ends of the evaporator 112 are wrapped by the side frame 1112 to shield and protect the pipe connection positions of the evaporator 112, preventing the pipe connection positions of the evaporator 112 from being impacted during the assembly process, which could cause the interface to loosen or fall off.

[0048] In this embodiment, the top end of the motor bracket 121 is connected to the upper bracket 1111, and the bottom end is connected to the water receiving tray 1113.

[0049] In fact, in this embodiment, the motor bracket 121 extends vertically, with its top end connected and fixed to the upper bracket 1111 of the evaporator bracket 111, and its bottom end connected and fixed to the water receiving tray 1113. The top and bottom ends of the motor bracket 121 are fixed separately through the upper bracket 1111 and the water receiving tray 1113, ensuring the stability of the connection structure between the evaporator assembly 110 and the axial flow air supply assembly 120.

[0050] Please refer to the following: Figure 6 and Figure 7 , Figure 6 As shown Figure 4 Enlarged diagram of region A in the middle. Figure 7 As shown Figure 5 A magnified view of region B in the middle.

[0051] In this embodiment, the bottom end of the motor bracket 121 is connected to the upper surface of the water receiving tray 1113, specifically through plug-in positioning and screw locking. The front side of the bottom wall of the upper bracket 1111 is provided with a first clearance groove 1114, and the rear side of the top end of the motor bracket 121 is embedded in the first clearance groove 1114 and connected to the upper bracket 1111.

[0052] The first clearance groove 1114 provides clearance in the front-to-back direction for the installation of the motor bracket 121. On the one hand, it allows the bottom of the motor bracket 121 to be inside the water receiving tray 1113 when it is installed, so that the condensate generated on its surface can flow downward into the water receiving tray 1113 to collect the condensate generated by the motor bracket 121. On the other hand, it effectively compresses the size of the connection structure between the evaporator assembly 110 and the axial air supply assembly 120 in the front-to-back direction, avoiding the axial air supply assembly 120 from occupying too much space in the front-to-back direction, thereby improving the compactness of the internal structure of the air conditioning cabinet 10.

[0053] In fact, the first clearance groove 1114 extends in the front-to-back direction, and the top of the motor bracket 121 is provided with a connecting sheet metal 1211 extending in the front-to-back direction. The rear end of the connecting sheet metal 1211 is provided with a first folded portion 1212 that folds upward. The rear end of the connecting sheet metal 1211 is embedded in the first clearance groove 1114, and the first folded portion 1212 is attached to the bottom wall of the first clearance groove 1114 and fixed by screws.

[0054] Understandably, the first clearance groove 1114 also serves to position the motor bracket 121 on the evaporator bracket 111. During assembly, it is only necessary to align the rear end of the connecting sheet metal 1211 and insert it into the first clearance groove 1114. When the first folded part 1212 is in contact with the bottom wall of the first clearance groove 1114, the through hole on the first folded part 1212 naturally aligns with the threaded hole on the bottom wall of the first clearance groove 1114. Simply pass the screw through the through hole on the first folded part 1212 and screw it into the threaded hole to quickly fix the top of the motor bracket 121.

[0055] Please refer to the following: Figure 8 , Figure 8 The diagram shows the connection structure of the air duct panel 130, the axial flow air supply assembly 120, and the evaporator assembly 110.

[0056] The rear side of the air duct panel 130 is connected to the front side of the evaporator bracket 111. The motor bracket 121 is located between the air duct panel 130 and the evaporator bracket 111. The air duct panel 130 is provided with an air duct 131, and the axial fan blade 123 is located inside the air duct 131.

[0057] In this embodiment, the top end of the air duct panel 130 is connected to the front surface of the upper bracket 1111 of the evaporator bracket 111, which can be fixed by screws; the bottom end of the air duct panel 130 is connected to the front surface of the water receiving tray 1113 of the evaporator bracket 111, which can be positioned by plugging and fixed by screws.

[0058] The air duct 131 extends through the air duct panel 130 in the front-to-back direction. In practical applications, after the axial air supply assembly 120 and the evaporator assembly 110 are assembled, the air duct panel 130 is then connected to the evaporator bracket 111. When the connection between the air duct panel 130 and the evaporator bracket 111 is completed, the axial fan blade 123 located in front of the motor bracket 121 extends coaxially into the air duct 131 that extends through the air duct panel 130.

[0059] In practical applications, the motor 122 drives the axial fan blade 123 to rotate inside the air duct 131, thereby creating a pressure difference between the front and rear ends of the air duct 131 to form an airflow from the air inlet to the air outlet.

[0060] In this embodiment, a second clearance groove 132 is provided on the air duct panel 130, and the front side of the top of the motor bracket 121 is embedded in the second clearance groove 132. It can be understood that the second clearance groove 132 also provides clearance in the front-rear direction for the motor bracket 121, so that when the air duct panel 130 is installed on the evaporator bracket 111, it can be in close contact with the front side of the evaporator bracket 111, and the connection structure between the evaporator assembly 110 and the air duct panel 130 is effectively compressed in the front-rear direction, avoiding excessive space occupation in the front-rear direction due to obstruction by the motor bracket 121, and further improving the compactness of the air conditioner cabinet 10.

[0061] Similarly, the second clearance groove 132 also extends in the front-rear direction, and the front end of the connecting sheet metal 1211 is also provided with an upwardly folded second folded part 1213. The front end of the connecting sheet metal 1211 is embedded in the second clearance groove 132, and the second folded part 1213 is attached to the bottom wall of the second clearance groove 132 and fixed by screws.

[0062] The insertion and engagement of the second clearance groove 132 with the connecting sheet metal 1211 serves to position the duct panel 130 on the evaporator bracket 111. After the connection between the motor bracket 121 and the evaporator bracket 111 is completed, the front end of the connecting sheet metal 1211 at the top of the motor bracket 121 protrudes from the upper bracket 1111. At this point, it is only necessary to align the second clearance groove 132 of the duct panel 130 with the connecting sheet metal 1211, so that the front end of the connecting sheet metal 1211 extends into the second clearance groove 132. When the second folded portion 1213 is in contact with the bottom wall of the second clearance groove 132, the insertion structure between the duct panel 130 and the evaporator bracket 111 is naturally completed, and the through hole on the duct panel 130 for screws to pass through is naturally aligned with the threaded hole on the evaporator bracket 111. Similarly, the second folded portion 1213 can also be connected and fixed to the duct panel 130 by means of connectors such as screws.

[0063] The air outlet grille 140 covers the end of the air duct 131 away from the motor bracket 121 and is connected to the air duct panel 130. In this embodiment, the side surface of the air duct panel 130 facing away from the motor bracket 121 is provided with a positioning pin 133 and a stud 134. The air outlet grille 140 is provided with a positioning hole 141 and a screw hole 142. The positioning hole 141 and the positioning pin 133 are inserted to position the air outlet grille 140 on the air duct panel 130. The screw passes through the screw hole 142 and is screwed into the stud 134 on the air duct panel 130 to fix the air outlet grille 140.

[0064] Understandably, the air outlet cover 140 is equipped with a grille structure, allowing the airflow from the air duct 131 to pass through the cover and exit through the air outlet. The air outlet cover 140 prevents users' fingers from entering the air duct 131 without affecting the airflow, thus providing a safety protection function.

[0065] In order to further simplify the structure of the air duct assembly 100 and improve the stability of the overall structure, the evaporator bracket 111 in this embodiment is an integrally molded structure, that is, the upper bracket 1111, the side frame 1112 and the water receiving tray 1113 are integrally molded structures.

[0066] Please see Figure 9 , Figure 9 The diagram shown is an exploded view of the evaporator assembly 110 in another embodiment.

[0067] In this embodiment, the upper support 1111 of the evaporator bracket 111 and the side frame 1112 are integrally formed, and the water receiving tray 1113 is an independent structure connected to the bottom end of the side frame 1112 via a connector. In another embodiment, the side frame 1112 and the water receiving tray 1113 can also be set as an integrally formed structure, and the upper support 1111 can be configured as an independent structure.

[0068] In summary, the air duct assembly 100 provided in this embodiment has the characteristics of simpler and more compact structure, easier assembly, and better heat exchange effect. Benefiting from the beneficial effects of the air duct assembly 100, the air conditioner cabinet 10 provided in this embodiment also has the characteristics of simpler structure, lower assembly difficulty, and better temperature regulation effect.

[0069] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
