While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0019] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0020] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0021] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0022] Existing air conditioners typically use a motor to drive a fan to rotate, thereby producing airflow. The motor and fan are connected via a bearing housing assembly, which is then fixed to the air conditioner's outer casing by a mounting bracket. This mounting bracket is usually snapped between two parts of the air conditioner's outer casing and is prone to radial wobbling during fan rotation, leading to abnormal noise and reducing product quality.

[0023] To address the issue of abnormal noise generated during fan rotation, this application proposes an indoor unit and an air conditioner incorporating the indoor unit. The indoor unit of this application reduces the number of connecting components between the bearing housing assembly and the casing, thereby reducing assembly clearance and thus reducing abnormal noise generated during fan rotation, improving product quality.

[0024] An air conditioner typically consists of an indoor unit and an outdoor unit. The outdoor unit is usually installed outdoors, while the indoor unit is usually installed indoors. The outdoor and indoor units work together to achieve the functions of cooling, heating, dehumidifying, and purifying the air, thereby achieving comfortable air quality.

[0025] During the cooling process of an air conditioner, the indoor heat exchanger is the evaporator. The refrigerant in the evaporator changes from a liquid state to a gaseous state, absorbing heat during evaporation. In this process, the evaporator exchanges heat with the air flowing through it, carrying away the heat from the air in the indoor unit. As a result, the air discharged from the indoor unit is cooled and released heat, causing the indoor unit to blow out cold air. At the same time, the outdoor heat exchanger is the condenser. The refrigerant in the condenser changes from a gaseous state to a liquid state, releasing heat during condensation. In this process, the condenser exchanges heat with the air flowing through it in the outdoor unit, carrying the heat from the condenser to the outside of the outdoor unit, thus achieving the cooling process.

[0026] During the heating process of an air conditioner, the outdoor heat exchanger acts as an evaporator. The refrigerant in the evaporator changes from a liquid state to a gaseous state, absorbing heat during evaporation. In this process, the evaporator exchanges heat with the air flowing through it, transferring the heat carried by the air in the outdoor unit to the refrigerant. Simultaneously, the indoor heat exchanger acts as a condenser. The refrigerant in the condenser changes from a gaseous state to a liquid state, releasing heat during condensation. In this process, the condenser exchanges heat with the air flowing through it, allowing the air in the indoor unit to carry away the heat carried by the condenser and exhaust it from the indoor unit to the outside of the room, causing the indoor unit to blow hot air. This is how the heating process is achieved.

[0027] Combination Figures 1 to 6 As shown, this application proposes an indoor unit 100. In some embodiments of this application, the indoor unit 100 includes a housing 10, a bearing housing assembly 20, and a fan 30. The housing 10 is provided with at least one mounting plate 11. The mounting plate 11 is provided with a first mounting hole 112 through a first direction X. At least a portion of the bearing housing assembly 20 is inserted into the first mounting hole 112. The fan 30 is disposed inside the housing 10 and is connected to the bearing housing assembly 20 in a manner that allows it to rotate around the first direction X. The first direction X is consistent with the axial direction of the fan 30.

[0028] Optionally, the housing 10 has a generally frame-like structure and forms the overall appearance of the indoor unit 100. Its interior has a receiving cavity for accommodating the bearing housing assembly 20 and the impeller 30. Optionally, the exterior of the housing 10 may also be provided with decorative panels to adjust the appearance of the indoor unit 100 to meet the needs of different users. The housing 10 includes at least one mounting plate 11. The mounting plate 11 can be one of the outer side plates at either end of the housing 10 along the first direction X, or the mounting plate 11 can be disposed inside the housing 10 and spaced apart from the outer side plates at both ends of the housing 10 along the first direction X.

[0029] For ease of description, this application only uses the mounting plate 11 as an example of the left outer side panel of the housing 10. It should be noted that when the user faces the indoor unit 100, the side of the indoor unit 100 to the user's left is the left side of the indoor unit 100, the side to the user's right is the right side, the side of the indoor unit 100 facing the user is the front side, and the side of the indoor unit 100 away from the user is the rear side. By using the outer side panel of the housing 10 as the mounting plate 11, the need for additional mounting plates 11 can be reduced, as can the space occupied by the mounting plate 11 along the first direction X within the housing 10, thereby improving the utilization rate of the internal space of the housing 10. The mounting plate 11 can be integrally formed with the housing 10, thereby improving the connection strength between the mounting plate 11 and the housing 10. Alternatively, the mounting plate 11 can be formed separately and then assembled into the housing 10.

[0030] Optionally, the mounting plate 11 has a first mounting hole 112 extending through it along the first direction X. The first mounting hole 112 may be located approximately at the center of the mounting plate 11. At least a portion of the bearing housing assembly 20 is inserted into the first mounting hole 112, including the bearing housing assembly 20 being completely inserted into the first mounting hole 112. Alternatively, one end of the bearing housing assembly 20 facing the impeller 30 or the other end facing away from the impeller 30 may extend outside the first mounting hole 112 for connection or fixation with other structures.

[0031] Optionally, the impeller 30 is disposed inside the housing 10 and connected to the bearing housing assembly 20 in a manner that allows it to rotate about a first direction X, wherein the first direction X is consistent with the axial direction of the impeller 30. The impeller 30 is connected to the bearing housing assembly 20 via a connecting shaft 31, thereby supporting the impeller 30 to rotate about the first direction X via the bearing housing assembly 20. Optionally, the impeller 30 is generally connected to a drive component, such as a motor 40, away from the bearing housing assembly 20, and can rotate about its own axial direction under the action of the motor 40, thereby forming airflow and realizing the air supply of the indoor unit 100. The impeller 30 may include a vortex impeller and a cross-flow impeller, which is not limited in this application. For ease of description, the embodiments of this application only use a cross-flow impeller as an example for illustration.

[0032] According to the indoor unit 100 of this application, by having a first mounting hole 112 provided through the mounting plate 11 of the housing 10, the bearing housing assembly 20 can be inserted into the first mounting hole 112 of the mounting plate 11, thereby reducing the number of connecting components between the bearing housing assembly 20 and the housing 10, reducing the assembly gap, and thus reducing the abnormal noise generated by the impeller 30 during rotation, and improving product quality.

[0033] Combination Figures 1 to 8 As shown, in some embodiments of this application, the bearing housing assembly 20 includes a bearing housing sleeve 21 and a bearing housing 22. The bearing housing sleeve 21 is fitted over the bearing housing 22, and the impeller 30 is rotatably connected to the bearing housing 22.

[0034] Optionally, the bearing housing 21 has a generally cylindrical structure, with a second mounting hole 215 extending through its interior along the first direction X. The bearing housing 22 is inserted into the second mounting hole 215 and connected to the bearing housing 21. Optionally, the bearing housing 22 and the bearing housing 21 can be an interference fit, thereby improving the connection strength between the bearing housing 22 and the bearing housing 21 and reducing axial or radial wobble between them. A third mounting hole 221 extends through the interior of the bearing housing 22. The end of the impeller 30 facing the bearing housing 22 along the first direction X has a connecting shaft 31. The end of the connecting shaft 31 facing the bearing housing 22 is inserted into the third mounting hole 221 in a manner that allows it to rotate around the first direction X, thereby supporting the impeller 30 to rotate around the first direction X via the bearing housing 22.

[0035] Optionally, a bearing 23 is also provided in the third mounting hole 221. The bearing 23 is fixed to the inner wall of the third mounting hole 221, and the end of the connecting shaft 31 is inserted into the bearing hole of the bearing 23, thereby facilitating the rotation of the connecting shaft 31 relative to the bearing seat 22 and reducing the friction between the connecting shaft 31 and the bearing seat 22 when rotating. Optionally, the connecting shaft 31 can be a part of the structure of the impeller 30 itself, that is, the connecting shaft 31 is integrally formed with the impeller 30 and protrudes from the side of the impeller 30 facing the bearing seat 22. Alternatively, the connecting shaft 31 and the impeller 30 can be formed separately, and the formed connecting shaft 31 and the impeller 30 can be assembled together.

[0036] Combination Figures 1 to 7 As shown, in some embodiments of this application, the first mounting hole 112 is provided with a first rib 113 inside, the first rib 113 is at least partially annular, and the outer peripheral surface of the bearing seat 21 is provided with a first annular groove 214 that matches and connects with the first rib 113.

[0037] Optionally, the first rib 113 protrudes from the inner wall of the first mounting hole 112 and extends circumferentially along the first mounting hole 112. The outer circumferential surface of the bearing housing 21 is provided with a first annular groove 214, which can be matched and connected with the first rib 113. When the bearing housing 21 is inserted into the first mounting hole 112, the first annular groove 214 is fitted over the outside of the first rib 113, thereby limiting the bearing housing 21 radially and axially through the first rib 113. Optionally, to improve the reliability of the first rib 113 in limiting the bearing housing 21 and reduce the axial detachment of the bearing housing 21 from the mounting plate 11, the first rib 113 can be a complete annular rib.

[0038] Combination Figures 1 to 7As shown, in some embodiments of this application, the bearing housing 21 includes a main body 211 and a spring plate 213. Along the circumference of the bearing housing 21, the main body 211 is provided with at least one notch 212, which is connected to the end face of the bearing housing 21 away from the impeller 30. The spring plate 213 is provided at the notch 212. The main body 211 and the spring plate 213 are respectively provided with a portion of the first annular groove 214. The spring plate 213 is configured to be elastically deformed along the radial direction of the bearing housing 21 when under compression.

[0039] Optionally, the main body 211 has a generally cylindrical structure with a second mounting hole 215 extending through its interior. Along the circumference of the main body 211, multiple notches 212 are spaced apart, with the end of the notch 212 facing the impeller 30 spaced apart from the end face of the main body 211 facing the impeller 30. The other end of the notch 212 away from the impeller 30 is connected to the other end face of the main body 211 away from the impeller 30, thus facilitating radial deformation of the main body 211 under pressure, allowing the bearing housing 21 to be inserted into the first mounting hole 112. A spring plate 213 is located at the notch 212. The spring plate 213 has a generally sheet-like structure, spaced apart from both sides of the main body 211 along its circumference, thus facilitating elastic deformation of the spring plate 213 along the radial direction of the bearing housing 21 under pressure. The main body 211 and the spring piece 213 are respectively provided with a portion of the first annular groove 214. Optionally, the radial dimension of the main body 211 is slightly larger than the dimension of the first mounting hole 112, so that when the bearing housing 21 is inserted into the first mounting hole 112, the bearing housing 21 can be interference-fitted with the first mounting hole 112, thereby reducing the axial and radial wobbling of the bearing housing 21.

[0040] Combination Figures 1 to 8 As shown, in some embodiments of this application, the bearing housing 21 is provided with a second mounting hole 215 through the first direction X, the inner wall surface of the second mounting hole 215 is provided with a second rib 216 extending circumferentially along the second mounting hole 215, the bearing housing 22 is inserted into the second mounting hole 215, and the outer surface of the bearing housing 22 is provided with a second annular groove 222 that matches and connects with the second rib 216.

[0041] Optionally, the second rib 216 protrudes from the inner wall of the second mounting hole 215 and extends circumferentially along the second mounting hole 215. The outer circumferential surface of the bearing housing 22 is provided with a second annular groove 222, which can be matched and connected with the second rib 216. When the bearing housing 22 is inserted into the second mounting hole 215, the second annular groove 222 is fitted over the outside of the second rib 216, thereby limiting the bearing housing 22 radially and axially through the second rib 216. Optionally, the second rib 216 can be a partially annular rib, that is, the second rib 216 does not form a complete annular structure, thus facilitating the insertion of the bearing housing 22 into the second mounting hole 215. Optionally, there can be multiple second ribs 216, which are spaced apart circumferentially along the second mounting hole 215, thereby improving the limiting of the bearing housing 22 through the multiple second ribs 216. Optionally, the end face of the bearing housing 22 for insertion into the bearing housing sleeve 21 is provided with a guide surface 223. The guide surface 223 can be a flat surface or an arc-shaped surface, thereby facilitating the insertion of the bearing housing 22 into the second mounting hole 215. Optionally, the end face of the other end of the bearing housing 22 is provided with a plurality of protrusions 224. The plurality of protrusions 224 are spaced apart along the circumference of the bearing housing 22 on the outer surface of the bearing housing 22, so that when the bearing housing 22 is inserted into the second mounting hole 215, the plurality of protrusions 224 can abut against the inner wall surface of the second mounting hole 215, thereby improving the positioning effect of the bearing housing 22 in the bearing housing sleeve 21.

[0042] Combination Figures 1 to 8 As shown, in some embodiments of this application, the end face of the bearing housing 21 facing away from the impeller 30 is provided with a baffle 217. The baffle 217 extends radially inward along the second mounting hole 215 and blocks part of the second mounting hole 215 along the first direction X.

[0043] Optionally, a baffle 217 is disposed at the front end of the bearing housing sleeve 21 along the insertion direction of the bearing housing 22 and extends toward the interior of the second mounting hole 215, thereby blocking part of the second mounting hole 215. When the bearing housing 22 is inserted into the bearing housing sleeve 21, the baffle 217 is disposed at the front end of the bearing housing 22 along the insertion direction, so that when the bearing housing 22 is impacted in the direction toward the baffle 217 and moves toward the baffle 217, the end face of the bearing housing 22 can abut against the baffle 217, thereby reducing the occurrence of the bearing housing 22 disengaging from the second mounting hole 215 along the first direction X.

[0044] Combination Figures 1 to 8 As shown, in some embodiments of this application, the bearing housing 22 includes a rubber component, and the bearing housing 22 is snapped into the interior of the bearing housing sleeve 21.

[0045] Optionally, the rubber component can undergo elastic deformation under compression, thereby facilitating the insertion of the bearing housing 22 into the bearing housing sleeve 21 after compression, and the inserted bearing housing 22 can be interference-fitted with the bearing housing sleeve 21 to improve the connection strength between the bearing housing 22 and the bearing housing sleeve 21.

[0046] Combination Figures 1 to 7 As shown, in some embodiments of this application, a portion of the mounting plate 11 extends toward the impeller 30 and forms an extended end 111, with a first mounting hole 112 penetrating through the interior of the extended end 111.

[0047] Optionally, the bearing housing assembly 20 has a certain length along the first direction X. If the mounting plate 11 is configured with a uniform wall thickness in the radial direction and has a through-hole 112, the weight of the mounting plate 11 will increase, thus increasing the cost. By protruding a portion of the mounting plate 11 to form an extended end 111, and having a through-hole 112 in the extended end 111, the dimension of the extended end 111 along the first direction X is larger than the dimension of the portion of the mounting plate 11 surrounding the extended end 111. This increases only the dimension along the first direction X at the location of the extended end 111, reducing the weight of the mounting plate 11 and lowering the cost. It also facilitates the installation of other structures on the outer periphery of the extended end 111, improving the space utilization rate inside the housing 10.

[0048] Combination Figures 1 to 6 As shown, in some embodiments of this application, the indoor unit 100 further includes a motor 40, which and the bearing housing assembly 20 are respectively disposed on both sides of the fan wheel 30 along the first direction X. The motor 40 is connected to the fan wheel 30 for transmission and is used to drive the fan wheel 30 to rotate.

[0049] Optionally, the motor 40 is located on the side of the wind turbine 30 away from the bearing housing assembly 20. The output shaft of the motor 40 is connected to the wind turbine and is used to drive the wind turbine 30 to rotate around the first direction X. Meanwhile, the bearing housing assembly 20 is located on the other side of the wind turbine 30 away from the motor 40 and is used to support the rotation of the wind turbine 30.

[0050] In some other embodiments of this application, a mounting plate 11 and a bearing housing assembly 20 may be provided between the motor 40 and the impeller 30. The motor 40 and the impeller 30 are respectively located on opposite sides of the mounting plate 11 along the first direction X. The bearing housing assembly 20 is inserted into the first mounting hole 112 of the mounting plate 11. The impeller 30 is connected to the bearing housing assembly 20 via a connecting shaft 31, with one end of the connecting shaft 31 facing away from the impeller 30 passing through the mounting plate 11 and connecting to the output shaft of the motor 40. Thus, the side of the impeller 30 closest to the motor 40 is supported by the bearing housing assembly 20.

[0051] Combination Figures 1 to 8As shown, a second aspect of this application also proposes an air conditioner including an indoor unit 100 of any of the above embodiments. The air conditioner also includes an outdoor unit, and the indoor unit 100 and the outdoor unit are connected by a refrigerant pipeline. Since the air conditioner in this application has an indoor unit of any of the above embodiments, it can achieve the same technical effect as the indoor unit of any of the above embodiments, and will not be described in detail here.

[0052] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
