[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The following is for reference. Figures 1-11 This invention describes an air conditioner according to an embodiment of the present invention.

[0040] An air conditioner according to an embodiment of the present invention includes: a housing assembly, an air duct assembly 20, and a heat exchanger assembly.

[0041] For example, the air conditioner is a split-type floor-standing air conditioner, which is divided into an indoor unit and an outdoor unit. The indoor unit includes the aforementioned casing assembly, air duct assembly 20, and heat exchanger assembly.

[0042] Reference Figure 1 The housing assembly has an air inlet and an air outlet. The housing assembly includes a housing, which includes a removable first shell plate, for example, the first shell plate can be the front panel of the housing. The air duct assembly 20 is disposed inside the housing and includes an air duct volute 28 and a fan 21.

[0043] For example, the fan 21 includes a fan wheel 22 and a motor 23. The motor shaft of the motor 23 is connected to the fan wheel 22. The duct casing 28 forms a duct 25, an air inlet 26, and an air outlet 27. The duct 25 connects the air inlet 26 and the air outlet 27. The fan wheel 22 is located inside the duct 25. When the air conditioner is working, the motor 23 drives the fan wheel 22 to rotate, driving the airflow from the air inlet into the air conditioner. After exchanging heat with the heat exchanger components, the airflow enters the duct 25 through the air inlet 26, is then thrown out by the fan wheel 22, and leaves the duct 25 through the air outlet 27. Finally, it leaves the air conditioner through the air outlet and is discharged into the room, thereby regulating the indoor temperature.

[0044] The duct volute 28 includes a first volute 29 and a second volute 30 disposed opposite to each other along a first direction (e.g., direction e1 in the attached figure), and the first volute 29 and the second volute 30 are detachably connected. By making the first volute 29 and the second volute 30 detachably connected, the first volute 29 and the second volute 30 can be separated. The first direction can be a left-right direction.

[0045] For example, the first volute 29 and the second volute 30 can be detachably connected by fastener 45.

[0046] The fan 21 is mounted on the second volute 30, and the first volute 29 is fixedly mounted on the housing assembly. The second volute 30 is slidably connected to the housing assembly and detachable relative to the housing assembly. The second volute 30 is slidable relative to the housing assembly and the first volute 29 along a second direction, allowing the second volute 30 and the fan 21 to be removed from or installed into the housing. The first shell plate is located on one side of the air duct assembly 20 along the second direction (e.g., direction e2 in the attached figure), and the second direction is perpendicular to the first direction. The heat exchanger assembly is located inside the housing assembly. The second direction can be a front-to-back direction.

[0047] By configuring the duct housing 28 of the duct assembly 20 as a detachably connected first housing 29 and second housing 30, wherein the first housing 29 is fixed to the housing assembly, and the second housing 30 is slidably connected to the housing assembly, and the fan 21 is mounted on the slidable second housing 30, when the duct assembly 20 needs to be disassembled, the first housing plate of the housing assembly can be removed first, then the connection between the first housing 29 and the second housing 30 can be released, and then the second housing 30, together with the fan 21, can be slid out of the housing assembly along the second direction, thereby facilitating the removal of the first housing 29. The second volute 30 and the fan 21 are removed from the housing assembly. At this time, the fan 21 installed on the second volute 30 is also exposed. This not only makes it easier to maintain and clean the second volute 30, but also makes it easier to maintain and clean the fan 21, reducing the difficulty of disassembling the air duct assembly 20. After the air duct assembly 20 is maintained, the second volute 30 together with the fan 21 can be slid into the housing assembly along the second direction. After the second volute 30 is slid into place, it is connected to the first volute 29, which also reduces the difficulty of installing the air duct assembly 20.

[0048] The following is a brief explanation of the disassembly and assembly process of the air duct assembly 20, taking the first direction as the left-right direction, the second direction as the front-back direction, and the first shell plate as the front panel of the casing.

[0049] When personnel need to disassemble the air duct assembly 20, they should first open the first shell panel of the housing assembly from the front of the air conditioner, then disconnect the first volute 29 from the second volute 30. Next, grasp the second volute 30 and slide it forward along with the fan 21 until both the second volute 30 and the fan 21 are removed from the housing. Personnel can then separate the second volute 30 from the fan 21 and perform corresponding cleaning or maintenance. Furthermore, since the second volute 30 and the fan 21 have been removed, the first volute 29 in the air duct assembly 20 is exposed. Personnel can then use cleaning or maintenance tools to directly reach into the vicinity of the second volute 30 from the front to clean or maintain it.

[0050] When relevant personnel need to install the air duct assembly 20, the fan 21 is first housed in the second volute 30. Then, the fan 21 and the second volute 30 are slid together as a whole from front to back into the housing assembly. After the second volute 30 is slid into place, the first volute 29 is connected to the second volute 30 to prevent the second volute 30 from moving or sliding inside the air conditioner.

[0051] According to the air conditioner of this utility model embodiment, by configuring the air duct housing 28 of the air duct assembly 20 as a detachably connected first housing 29 and second housing 30, wherein the first housing 29 is fixed to the housing assembly, the second housing 30 is slidably connected to the housing assembly, and the fan 21 is installed on the slidable second housing 30, when it is necessary to disassemble the air duct assembly 20, the first shell plate of the housing assembly can be removed first, then the connection between the first housing 29 and the second housing 30 can be released, and then the second housing 30 together with the fan 21 can be slid out of the housing assembly along the second direction. The second volute 30 and the fan 21 can be easily removed from the housing assembly, and the fan 21 installed in the second volute 30 is also exposed. This not only makes it easier to maintain and clean the second volute 30, but also makes it easier to maintain and clean the fan 21, reducing the difficulty of disassembling the air duct assembly 20. After the air duct assembly 20 is maintained, the second volute 30 and the fan 21 can be slid into the housing assembly along the second direction. After the second volute 30 is slid into place, it can be connected to the first volute 29, which also reduces the difficulty of installing the air duct assembly 20.

[0052] According to some embodiments of this utility model, refer to Figure 9 and Figure 10 The first volute 29 has a first sealing surface 31 on the side facing the second volute 30, and the second volute 30 has a second sealing surface 32 on the side facing the first volute 29. Both the first sealing surface 31 and the second sealing surface 32 are located on the outer periphery of the air duct 25, and the first sealing surface 31 and the second sealing surface 32 abut against each other in a first direction to seal. By making the first sealing surface 31 and the second sealing surface 32 both located on the outer periphery of the air duct 25, and by making the first sealing surface 31 and the second sealing surface 32 abut against each other in a first direction to seal, the first volute 29 and the second volute 30 can have good sealing performance, reducing airflow leakage in the air duct 25. Furthermore, when the second volute 30 slides in a second direction, the second sealing surface 32 can slide along the relative first sealing surface 31, making it easier to separate and disassemble the first volute 29 and the second volute 30.

[0053] According to some embodiments of this utility model, refer to Figure 9 and Figure 10The plane containing the second sealing surface 32 is the mating surface 33, and the fan 21 is located on the side of the mating surface 33 closest to the second volute 30. By positioning the fan 21 completely on the side of the second volute 30, interference between the fan 21 and the first volute 29 can be better avoided when the second volute 30, along with the fan 21, is slid together in the second direction to remove it from the housing, making the disassembly process smoother. Furthermore, during installation, when the second volute 30, along with the fan 21, is slid together in the second direction into the housing, interference between the fan 21 and the first volute 29 can also be better avoided, making the installation process smoother.

[0054] According to some embodiments of this utility model, refer to Figure 9 and Figure 10 The outer wall of the first volute 29 is provided with a first guide structure 34, and the outer wall of the second volute 30 is provided with a second guide structure 35. The second guide structure 35 cooperates with the first guide structure 34 and can slide relative to each other along the second direction. By providing a first guide structure 34 on the outer wall of the first volute 29 and a second guide structure 35 on the outer wall of the second volute 30, the second guide structure 35 cooperates with the first guide structure 34. Furthermore, by allowing the second guide structure 35 and the first guide structure 34 to slide relative to each other along a second direction, when the second volute 30 is slidably removed along the second direction, the cooperation of the first guide structure 34 and the second guide structure 35 provides good guidance for the sliding of the second volute 30, making the sliding process of the second volute 30 more stable. Moreover, during the process of the second volute 30 sliding into the housing along the second direction, the cooperation of the first guide structure 34 and the second guide structure 35 ensures that the second volute 30 is properly installed and better cooperates with the first volute 29, thereby better guaranteeing the sealing between the second volute 30 and the first volute 29.

[0055] For example, refer to Figure 6 , Figure 9 and Figure 10 Two first guide structures 34 are provided on the outer wall of the first volute 29. The two first guide structures 34 are arranged at intervals along a third direction (e.g., the e3 direction in the attached figure). Correspondingly, two second guide structures 35 are provided on the outer wall of the second volute 30. The two second guide structures 35 are arranged at intervals along a third direction. The two first guide structures 34 cooperate with the two second guide structures 35 respectively and can slide relative to each other along the second direction.

[0056] According to some embodiments of this utility model, refer to Figure 6The first guide structure 34 includes a guide groove 36 extending along a second direction, and the second guide structure 35 includes a guide rib 37, at least a portion of which is accommodated in the guide groove 36. By accommodating at least a portion of the guide rib 37 in the guide groove 36, when the second volute 30 is slidably removed along the second direction, the cooperation between the guide groove 36 and the guide rib 37 provides better guidance for the sliding of the second volute 30, making the sliding process of the second volute 30 more stable. Furthermore, during the process of the second volute 30 sliding into the housing along the second direction, the cooperation between the guide groove 36 and the guide rib 37 ensures that the second volute 30 is properly installed in place to better cooperate with the first volute 29, thereby better guaranteeing the sealing between the second volute 30 and the first volute 29.

[0057] According to some embodiments of this utility model, refer to Figures 3-5 The housing assembly includes a sliding member 11 connected to the housing. The sliding member 11 has a groove 12 extending in a second direction. The second volute 30 is provided with a sliding plate 38, at least a portion of which is accommodated in the groove 12 and is slidable relative to the groove 12 in the second direction. By having the sliding member 11 have a groove 12 extending in the second direction, and the second volute 30 have a sliding plate 38, at least a portion of which is accommodated in the groove 12, the sliding plate 38 is ensured to slide relative to the sliding member 11 in the second direction. This allows the second volute 30 to slide relative to the housing in the second direction, enabling personnel to remove or install the second volute 30 from the housing by sliding it. Furthermore, it prevents the sliding member 11 from disengaging from the guide groove 36, avoiding a decrease in sealing performance caused by the first volute 29 and the second volute 30 disengaging from their contact.

[0058] According to some embodiments of this utility model, refer to Figure 5A limiting baffle 39 is connected to one side of the sliding plate 38 along the second direction. The limiting baffle 39 is connected to the sliding plate 38. The sliding groove 11 has a limiting surface 13 facing the first shell plate. The limiting baffle 39 is located on the side of the limiting surface 13 closer to the first shell plate. When the second volute 30 is installed in place, the limiting baffle 39 abuts against the limiting surface 13 in the second direction. When the relevant personnel install the second volute 30 onto the housing, the sliding plate 38 is usually pushed along the sliding groove 11 from the side of the sliding groove 11 closer to the first shell plate until the limiting baffle 39 abuts against the limiting surface 13 in the second direction. By ensuring that the limiting baffle 39 abuts against the limiting surface 13 in the second direction when the second volute 30 is installed in place, it can indicate to relevant personnel that the second volute 30 has been installed in place when they install it onto the housing. This prevents personnel from pushing the second volute 30 too much in the second direction, which could damage the second volute 30. It can also prevent the second volute 30 from shifting in position, which could reduce the sealing performance between the second volute 30 and the first volute 29.

[0059] According to some embodiments of this utility model, refer to Figures 3-5 There are two sliding groove components 11, which are arranged at intervals along a third direction (e.g., direction e3 in the attached figure). There are also two sliding plates 38, which are arranged at intervals along the third direction. The two sliding plates 38 mate with the two sliding groove components 11 respectively, and are perpendicular to each other in the first direction, second direction, and third direction. By using two sliding groove components 11, which are arranged at intervals along the third direction, the limiting effect of the sliding groove components 11 on the sliding plates 38 is more sufficient, ensuring that the sliding plates 38 are always limited by the sliding groove components 11 in the third direction.

[0060] For example, the third direction can be the up and down direction. The sliding plate 38 can be supported by the sliding groove 11. During the process of the second volute 30 and the fan 21 sliding along the second direction, the sliding groove 11 can provide support for the second volute 30.

[0061] According to some embodiments of this utility model, refer to Figure 11The housing assembly also includes a mounting bracket 14 connected to the housing. A sliding member 11 is mounted on the mounting bracket 14, and the mounting bracket 14 is detachably connected to either the housing or the sliding member 11. By including the mounting bracket 14 in the housing assembly, and connecting the mounting bracket 14 to the housing, the housing can be prevented from deforming due to excessive force during disassembly or installation of the second volute 30. By mounting the sliding member 11 on the mounting bracket 14, and connecting the mounting bracket 14 to the housing, the sliding member 11 can be fixed relative to the housing. The detachable connection between the mounting bracket 14 and either the housing or the sliding member 11 allows for easier maintenance or repair by directly removing the sliding member 11 from the mounting bracket 14 or removing the mounting bracket 14 and the sliding member 11 from the housing.

[0062] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The second volute 30 includes a volute body 40 and a reinforcing plate 41. The volute body 40 and the first volute 29 together define the air outlet duct 25, and the volute body 40 abuts against the first volute 29 in a first direction. The volute body 40 is made of plastic, and the reinforcing plate 41 is made of metal. The reinforcing plate 41 is disposed on the outer wall surface of the volute body 40 and connected to the volute body 40. A sliding plate 38 is connected to the reinforcing plate 41. The fan 21 includes a motor 23, and the motor housing 24 of the motor 23 is connected to at least one of the reinforcing plate 41 and the volute body 40. For example, the motor housing 24 is connected to the reinforcing plate 41; for example, the motor housing 24 is connected to the volute body 40; and for another example, the motor housing 24 is connected to both the reinforcing plate 41 and the volute body. By having the volute body 40 abut against the second volute 30 in a first direction, the sealing performance between the first volute 29 and the volute body 40 can be improved. By making the reinforcing plate 41 a metal part, the structural strength of the reinforcing plate 41 can be increased, which facilitates the connection between the second volute 30 and components such as the sliding plate 38; in addition, the structural strength of the second volute 30 can also be increased, so that the weight of the second volute 30 is small and the structural strength meets the requirements.

[0063] According to some embodiments of the present invention, the volute body 40 is a foam plastic component. For example, the volute body 40 can be polystyrene (EPS). By making the volute body 40 a foam plastic component, the manufacturing cost of the volute body 40 can be reduced; and the sealing performance between the volute body 40 and the first volute 29 can be improved.

[0064] According to some embodiments of this utility model, the first volute 29 is a plastic part, and the density of the volute body 40 is less than the density of the first volute 29. For example, the first volute 29 can be made of polycarbonate (PC). By making the density of the volute body 40 less than the density of the first volute 29, the volute body 40 has a certain elastic deformation capacity, which can make the seal between the volute body 40 and the first volute 29 more complete, and make the weight of the volute body 40 lighter, thereby making the overall weight of the second volute 30 lighter and easier to disassemble.

The impeller 22 is located inside the impeller 22 cavity. For example, the impeller 22 can be a centrifugal impeller 22. When the air conditioner is working, the centrifugal impeller 22 drives the airflow to enter the air conditioner from the air inlet. After the airflow exchanges heat with the heat exchanger assembly, it enters the air outlet 25 along the axial direction of the centrifugal impeller 22 through the airflow inlet 26 on the first volute 29, and is then thrown out circumferentially by the centrifugal impeller 22, leaving the air outlet 27 and finally leaving the air conditioner through the air outlet.

[0070] According to some embodiments of this utility model, refer to Figure 1 and Figure 10 The inner wall of the first volute 29 has a groove 48, which is located within the air outlet channel 252. By forming a groove 48 on the inner wall of the first volute 29 and having the groove 48 located within the air outlet channel 252, the noise generated during the airflow through the air outlet channel 252 is reflected and reduced by the inner wall of the groove 48, thereby reducing the noise generated when air is discharged from the air outlet channel 252.

[0071] According to some embodiments of this utility model, refer to Figure 10 The groove 48 is arc-shaped. By making the groove 48 arc-shaped, the airflow can flow more smoothly through the groove 48 during the process of airflow through the air outlet channel 252, reducing the noise of airflow.

[0072] According to some embodiments of this utility model, refer to Figure 10 A portion of the first volute 29 protrudes outward to form a groove 48 on the inner side of the first volute 29. By making a portion of the first volute 29 protrude outward, the flow area of ​​the air outlet duct 252 can be increased, noise can be reduced, and the structural strength of the portion of the first volute 29 located in the air outlet duct 252 can be increased.

[0073] According to some embodiments of this utility model, the inner wall of the groove 48 is provided with a sound-absorbing material layer. For example, the sound-absorbing material layer is a sponge. By providing a sound-absorbing material layer on the inner wall of the groove 48, the noise generated when the airflow flows through the air outlet channel 252 can be absorbed and reduced by the sound-absorbing material layer, thereby reducing the air outlet noise of the air duct assembly 20.
