If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0040] This invention proposes an air conditioner cabinet unit.

[0041] In one embodiment of the present invention, reference is made to... Figures 1 to 3 and combined Figures 10 to 12 The air conditioner unit 1 includes:

[0042] The housing 10 includes a back plate 110, a cover plate 120, a left panel 130, and a right panel 140. The back plate 110 and the cover plate 120 form a cavity 100. The left panel 130 and the right panel 140 are movably mounted on the back plate 110 or the cover plate 120, and can be opened by swinging left and right relative to the cover plate 120 to expose the cover plate 120.

[0043] The air duct assembly 40 includes a volute 410, a volute tongue 420, an air outlet frame 440, and an impeller 430. The volute 410 is installed inside the cavity 100, and the impeller 430 is installed inside the volute 410.

[0044] The left panel 130 and the right panel 140 are respectively equipped with the volute tongue 420 and the air outlet frame 440. The cover plate 120 is provided with a first window 121 for the volute tongue 420 and the air outlet frame 440 to abut against the volute 410.

[0045] This air conditioner unit 1 is applicable to both round and square cabinet units. The following explanation uses a round cabinet unit as an example. In this embodiment, the back panel 110, cover panel 120, left panel 130, and right panel 140 are all curved. The back panel 110 and cover panel 120, when joined, form a circle or a near-circular shape. The left panel 130 and right panel 140 are located on the outer side of the cover panel 120. Thus, the back panel 110 and the cover panel form the exterior surface of the air conditioner unit 1. The outer surfaces of the left panel 130 and right panel 140 are flush with the outer surface of the back panel 110, making the overall appearance of the air conditioner unit 1 smoother and enhancing its aesthetic appeal. The left panel 130 and right panel 140 are movably connected to the two sides of the back panel 110. The left panel 130 can swing to the left relative to the cover panel 120, and the right panel 140 can swing to the right relative to the cover panel 120, ultimately revealing the cover panel 120. The left panel 130 and the right panel 140 can be connected to the back panel 110 by means of a connecting mechanism such as a swing arm 160 or a linkage mechanism, so that the left panel 130 and the right panel 140 can swing. The specific form of the connecting structure is not specifically limited here.

[0046] The air duct assembly 40 includes components such as a volute 410, a volute tongue 420, an impeller 430, and an air outlet frame 440. The volute 410 extends vertically, and the volute tongue 420 abuts against one side of the volute 410, forming an air outlet. The impeller 430 is vertically disposed inside the volute 410. When the impeller 430 rotates, the airflow inside the volute 410 is blown out from the air outlet between the volute 410 and the volute tongue 420. The air outlet frame 440 is located at the air outlet. The impeller 430 can be a cross-flow impeller 430 or a centrifugal impeller 430, but a cross-flow impeller 430 is generally preferred to reduce the noise of the air conditioning unit 1.

[0047] In existing air conditioners, the internal components are generally difficult to disassemble and clean. After prolonged use, dust easily accumulates inside, fostering bacterial growth and leading to poor airflow quality, which can harm human health and negatively impact user experience. Furthermore, dust buildup increases the likelihood of blockages, affecting the air conditioner's normal operation. Typically, the air duct components inside the air conditioner are difficult to disassemble and clean, making them one of the most prone to blockages.

[0048] To improve the above situation and facilitate the cleaning of the air duct assembly 40 inside the air conditioner unit 1, the volute 410 of the air duct assembly 40 is installed inside the cavity 100, the impeller 430 is installed inside the volute 410, the volute tongue 420 is installed on the inner side of the left panel 130, and the air outlet frame 440 is installed on the inner side of the right panel 140. The cover plate 120 is provided with a first window 121 for the volute tongue 420 and the air outlet frame 440 to abut against the volute 410. When the left panel 130 and the right panel 140 are opened, the volute tongue 420 separates from the volute 410 through the first window 121 along with the left panel 130, and the air outlet frame 440 also separates from the volute 410 through the first window 121 along with the right panel 140. When the left panel 130 is closed, the volute tongue 420 abuts against the volute 410, and when the right panel 140 is closed, the air outlet frame 440 abuts against both the volute 410 and the volute tongue 420. It should be noted that, in other embodiments, the volute tongue 420 may be disposed on the inner side of the right panel 140, and the air outlet frame 440 is disposed on the inner side of the left panel 130 accordingly.

[0049] When the interior of the air conditioner unit 1 needs to be cleaned, the left panel 130 and the right panel 140 are opened. At this time, the volute tongue 420 and the air outlet frame 440 separate from the volute housing 410, thereby exposing the volute housing 410 and the impeller 430 inside the volute housing 410. This facilitates cleaning of the air duct and impeller 430 inside the volute housing 410 through the first window 121. In this embodiment, when the left panel 130 and the right panel 140 are opened, the volute housing 410 and the impeller 430 inside the air duct assembly 40 can be exposed, making it easy to clean the volute housing 410, volute tongue 420, air outlet frame 440, and impeller 430 in the air duct assembly 40. Because the inside of the air duct assembly 40 is easy to clean, it can maintain a better cleanliness, reducing the probability of bacteria growth inside the air duct assembly 40, improving air quality and human comfort, and effectively improving the user experience; at the same time, the dirt and blockage inside the air duct assembly 40 is improved, which also ensures the normal operation of the air duct assembly 40 and extends the service life of the air conditioner unit 1.

[0050] The technical solution of this invention employs a volute tongue 420 installed on one of the left panel 130 and the right panel 140, and an air outlet frame 440 installed on the other. When the left panel 130 and the right panel 140 are opened, the volute tongue 420 and the air outlet frame 440 separate from the volute housing 410, thereby exposing the volute housing 410 and the impeller 430 inside the volute housing 410. This allows for easy cleaning of the volute housing 410, volute tongue 420, air outlet frame 440, and impeller 430 within the air duct assembly 40. Because the interior of the air duct assembly 40 can be easily cleaned, it maintains a better cleanliness, reducing the probability of bacterial growth inside the air duct assembly 40, improving airflow quality and human comfort, and effectively enhancing the user experience. Simultaneously, the improvement in the degree of dirt blockage within the air duct assembly 40 ensures its normal operation and extends the service life of the air conditioning unit 1.

[0051] Typically, the heat exchanger 30 is fixed inside the air conditioner, making it difficult to clean. At the same time, the heat exchanger 30 is also prone to getting dirty and clogged. On the one hand, it can easily breed bacteria, affecting the quality of the airflow. On the other hand, it can also reduce the heat exchange efficiency of the heat exchanger 30, resulting in a significant reduction in the working performance of the air conditioner.

[0052] In this embodiment, a heat exchanger 30 and a heat exchanger support 20 are provided inside the cavity 100. The heat exchanger support 20 is connected to the back plate 110. An upper support 210 and a lower support 220 extend horizontally from the upper and lower ends of the heat exchanger 30, respectively. The two ends of the heat exchanger 30 are fixed to the upper support 210 and the lower support 220, respectively. The heat exchanger 30, the upper support 210, and the lower support 220 enclose a mounting cavity 60. A volute 410 is detachably installed in the mounting cavity 60, and the volute 410 enters and exits the mounting cavity 60 through the first window 121. In this way, the volute 410 can be removed from the mounting cavity 60, allowing the heat exchanger 30 to be exposed through the first window 121, thereby facilitating the cleaning of dust on the surface of the heat exchanger 30 and improving the degree of dirt clogging of the heat exchanger 30. On the one hand, it allows the heat exchanger 30 to maintain a better clean state, reducing the probability of bacteria growth in the heat exchanger 30 and improving the air quality; on the other hand, it also improves the dirt and blockage situation inside the air conditioning unit 1, ensuring the normal heat exchange of the heat exchanger 30 and effectively ensuring the normal and stable operation of the air conditioning unit 1.

[0053] The upper and lower ends of the volute 410 are connected to the upper support 210 and the lower support 220, respectively. The upper support 210 is provided with a clearance notch 211 corresponding to the upper end of the volute 410. The opening direction of the clearance notch 211 is set towards the cover plate 120 to facilitate the separation of the volute 410 from the upper support 210. The edge of the clearance notch 211 is connected to the upper end of the volute 410 with screws. The lower end of the volute 410 abuts against the lower support 220, and the lower end of the volute 410 is connected to the lower support 220 with screws. It should be emphasized that, in order to facilitate the disassembly of the volute 410 through the first window 121, the upper end of the volute 410 and the edge of the clearance notch 211 may be provided with a flange structure when necessary, so that the screws used to fix the upper end of the volute 410 and the edge of the clearance notch 211 are in the horizontal direction, and the disassembly direction of the screws is consistent with the orientation of the first window 121, thereby facilitating the installation and removal of screws from the first window 121; similarly, the lower end of the volute 410 and the lower support 220 may be provided with a flange structure when necessary, so that the screws used to fix the lower end of the volute 410 and the lower support 220 are in the horizontal direction, and the disassembly direction of the screws is consistent with the orientation of the first window 121, thereby facilitating the installation and removal of screws from the first window 121.

[0054] In this embodiment, a motor 450 and a motor cover 460 are disposed on the upper surface of the upper end of the volute 410. The motor 450 is located inside the motor cover 460. The motor cover 460 is detachably connected to the upper surface of the upper end of the volute 410 by screws, clips, or other means, thereby pressing and fixing the motor 450 between the motor cover 460 and the upper surface of the upper end of the volute 410. The rotating shaft of the motor 450 passes through the upper end of the volute 410 and is detachably connected to the upper end of the impeller 430 to enable the motor 450 to drive the impeller 430. When it is necessary to replace or repair the motor 450, the motor cover 460 is removed, and the rotating shaft of the motor 450 is separated from the impeller 430, thereby easily disassembling the motor 450. To facilitate the replacement or maintenance of the motor 450, a second window 122 is provided on the cover plate 120 corresponding to the position of the impeller 430 and the motor 450. When the left panel 130 and the right panel 140 are opened, the second window 122 is exposed, allowing easy disassembly and assembly of the motor 450. To facilitate the manufacture of the cover plate 120, in this embodiment, the first window 121 and the second window 122 are connected, thus enabling the disassembly and assembly of the motor 450 and the volute 410 through a single window.

[0055] The electrical control box 50 of the air conditioner unit 1 is located within the cavity 100, below the air duct assembly 40. The cover plate 120 has a third window 123 for disassembling and assembling the electrical control box 50. In some preferred embodiments, the third window 123 may be connected to the first window 121, or the third window 123, the first window 121, and the second window 122 may be connected to each other, in order to simplify the structure of the cover plate 120 and reduce the manufacturing difficulty of the cover plate 120.

[0056] Understandably, referring to Figures 4 to 12 When the air outlet frame 440 is installed on the left panel 130, the air outlet 150 is also located on the left panel 130 corresponding to the air outlet frame 440; when the air outlet frame 440 is installed on the right panel 140, the air outlet 150 is also located on the right panel 140 corresponding to the air outlet frame 440. The joint between the left panel 130 and the right panel 140 is positioned near the side of the cover plate 120, so that the air outlet 150 is located at the center of the front half of the air conditioner unit housing 10. That is, when the air outlet 150 is located on the left panel 130, the joint between the left panel 130 and the right panel 140 is located near the right side of the cover plate 120; when the air outlet 150 is located on the right panel 140, the joint between the left panel 130 and the right panel 140 is located near the left side of the cover plate 120.

[0057] The left panel 130 and the right panel 140 are engaged with each other on one side and locked to the cover plate 120 by snapping or magnetic attraction, thereby facilitating the opening and closing of the left panel 130 and the right panel 140.

[0058] In this embodiment, a swing arm 160 is provided between the left panel 130 and the right panel 140 and the back panel 110 to enable the left panel 130 and the right panel 140 to swing relative to the cover plate 120. The swing arm 160 extends horizontally inward from the inner side of the left panel 130 and the right panel 140, and the swing arm 160 is U-shaped. The free end of the swing arm 160 is pivotally connected to the back panel 110.

[0059] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
