Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to an air conditioner. Background Technology

[0002] With the development of science and technology, air conditioners are being used more and more, and there are more and more types of air conditioners, including wall-mounted units, floor-standing units, ducted units, and ceiling units. In particular, ceiling units are mostly installed on the ceiling of the room, and most of them are relatively large. In order to increase the air outlet area, multiple fan wheels are installed. The fan wheels are connected by bearings. When inspecting the entire fan assembly, the heat exchanger needs to be disassembled before the fan assembly can be disassembled, which makes the inspection and maintenance of the fan assembly too troublesome and difficult. Summary of the Invention

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0054] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0055] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0056] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0057] With the development of science and technology, air conditioners are increasingly used, and the types of air conditioners are also becoming more and more diverse, including wall-mounted units, floor-standing units, ducted units, and ceiling units. Ceiling units, in particular, are mostly installed on the ceiling and are generally quite large. To increase the airflow area, multiple fan wheels are installed, connected by bearings. When inspecting the entire fan assembly, the heat exchanger must be disassembled before the fan assembly can be disassembled, making the inspection and maintenance of the fan assembly overly cumbersome and difficult. The air conditioner provided in this application embodiment can improve the above problems. The air conditioner provided in this application embodiment simplifies the inspection and maintenance steps of the fan assembly, reduces the difficulty of fan assembly maintenance, and improves the overall convenience of air conditioner maintenance.

[0058] This application is described below with reference to the accompanying drawings and specific embodiments:

[0059] Figure 1 This paper shows a schematic diagram of the structure of an air conditioner 100 provided in an embodiment of this application. Figure 2 An exploded view of an air conditioner 100 provided in an embodiment of this application is shown. Figure 1 and Figure 2 As shown, this application embodiment provides an air conditioner 100. The air conditioner 100 provided by this application embodiment can simplify the maintenance steps of the fan assembly 150, reduce the maintenance difficulty of the fan assembly 150, and improve the maintenance convenience of the entire air conditioner 100.

[0060] Figure 3 This application provides a schematic diagram of the structure of an air conditioner 100 installed in a suspended ceiling 21, as shown in the embodiment. Figure 3 As shown, the air conditioner 100 includes a housing 110 and a panel assembly 122. In use, the housing 110 can be installed inside the ceiling 21. The housing 110 can be mounted on the top surface of the wall 23 via a hanger 22. The panel assembly 122 can extend beyond the ceiling 24, so that both the return air vent 114 and the air outlet vent 116 of the panel assembly 122 are connected to the indoor environment 25, with the airflow direction as follows: Figure 3As indicated by the middle arrow, panel assembly 122 is located at the bottom of the entire air conditioner 100, and only panel assembly 122 is outside the ceiling 24. The air conditioner 100 may also include a chassis assembly 124, which is disposed between panel assembly 122 and heat exchanger 130. A water collection tray 126 may be provided on chassis assembly 124, located below heat exchanger 130, for collecting condensate from heat exchanger 130.

[0061] Figure 4 A cross-sectional view of an air conditioner 100 provided in an embodiment of this application is shown. Figure 4 As shown, the air conditioner 100 includes: a housing 110, a panel assembly 122, a heat exchanger 130, a support base 140, and a fan assembly 150. The panel assembly 122 is detachably connected to the housing 110, and the housing 110 and the panel assembly 122 form a receiving cavity 112. The panel assembly 122 has a return air port 114 and an air outlet 116 communicating with the receiving cavity 112. The heat exchanger 130 and the support base 140 are both disposed within the receiving cavity 112, and the heat exchanger 130 is detachably mounted on the support base 140. The fan assembly 150 includes a driver 152, a plurality of impellers 154, and at least one bearing 156. The bearing 156 connects two adjacent impellers 154, and the driver 152 is drively connected to one of the impellers 154.

[0062] The housing 110 is the main structure of the entire air conditioner 100 and its basic component. It provides a base for installing the panel assembly 122, heat exchanger 130, support base 140, fan assembly 150, etc. The heat exchanger 130, support base 140, and fan assembly 150 can be installed in the housing 110, making the air conditioner 100 a complete unit and facilitating its transportation. Furthermore, the heat exchanger 130, support base 140, and fan assembly 150 can be installed inside the housing 110, which provides protection and reduces the risk of damage to these components.

[0063] It should be noted that the air conditioner 100 may include an indoor unit and an outdoor unit, or it may be an integrated air conditioner 100. In the case where the air conditioner 100 includes an indoor unit and an outdoor unit, the air conditioner 100 mentioned in this application refers to the indoor unit of the air conditioner 100 unless otherwise specified.

[0064] For ease of description, the housing 110 is defined to have a length direction X, a width direction Y, and a thickness direction. The thickness direction is the vertical direction of the air conditioner 100 in the use state. The cross-section of the housing 110 in the horizontal plane is approximately rectangular. This rectangle has a long side and a wide side. The direction of the long side is the length direction X of the housing 110, and the direction of the wide side is the width direction Y.

[0065] The heat exchanger 130 and the fan assembly 150 are installed inside the housing cavity 112. During the operation of the air conditioner 100, the fan assembly 150 allows air from the indoor environment 25 to enter the housing cavity 112 through the return air inlet 114 and exchange heat with the heat exchanger 130. After heat exchange, the air is blown out from the air outlet 116. Of the two assemblies, the heat exchanger 130 can be positioned closer to the return air inlet 114, and the fan assembly 150 closer to the air outlet 116, allowing the air blown from the air outlet 116 to travel a greater distance. To ensure that the airflow from the air outlet 116 covers a larger area along the length X direction of the housing 110, the impeller 154 can be made relatively long. However, if a single impeller 154 is made too long, it is prone to deformation during rotation, causing it to malfunction. In order to increase the air outlet coverage area, multiple impellers 154 can be installed. The multiple impellers 154 are arranged sequentially along the length direction X of the housing 110, thereby increasing the air outlet volume. Adjacent impellers 154 can be connected by bearings.

[0066] To allow for a compact internal arrangement of the air conditioner 100, the heat exchanger 130 and the fan assembly 150 may overlap in the height direction Z of the casing 110, such as... Figure 3 As shown at point W1, W1 represents the distance between the fan assembly 150 and the heat exchanger 130, which is only 4mm at its minimum. This means that the heat exchanger 130 may exist between the bearing 156 and the panel assembly 122. If the fan assembly 150 needs to be repaired, the heat exchanger 130 must be disassembled first. Due to the relatively large size of the heat exchanger 130, this arrangement makes the maintenance process of the fan assembly 150 particularly complex and difficult to operate.

[0067] Figure 5 A schematic diagram of the structure of the heat exchanger 130 and the support member 134 provided in the embodiment of this application is shown. Figure 6 It shows Figure 5 A magnified view of a portion of point A in the middle. (See image below.) Figure 5 and Figure 6As shown in this embodiment, the support member 134 is disposed within the receiving cavity 112. When the heat exchanger 130 is separated from the support base 140, the support member 134 can support the heat exchanger 130, allowing the heat exchanger 130 and the bearing member 156 to be spaced apart. With the support member 134 disposed within the receiving cavity 112, if the fan assembly 150 needs maintenance, the connection between the heat exchanger 130 and the support base 140 can be released after the panel assembly 122 and the chassis assembly 124 are disassembled. This allows the heat exchanger 130 to engage with the support member 134, thereby increasing the distance between the heat exchanger 130 and the bearing member 156. Maintenance personnel can then contact the connection between the bearing member 156 and the housing 110 through the gap between the heat exchanger 130 and the bearing member 156, allowing the fan assembly 150 to be disassembled from the housing 110.

[0068] In other words, in this embodiment of the application, if it is necessary to repair the fan assembly 150, the panel assembly 122 and the chassis assembly 124 can be removed from the housing 110 first. Then, the connection between the heat exchanger 130 and the support base 140 can be disconnected, and the heat exchanger 130 can be hung under the support member 134. The support member 134 can support the heat exchanger 130. The heat exchanger 130 and the bearing member 156 are spaced apart. The maintenance personnel can directly remove the bearing member 156 from the gap between the heat exchanger 130 and the fan assembly 150, so that the entire fan assembly 150 can be removed from the housing 110 for repair. In this embodiment, the fan assembly 150 can be repaired without removing the heat exchanger 130 from the housing 110. This operation method simplifies the repair steps of the fan assembly 150, reduces the repair difficulty of the fan assembly 150, and improves the repair convenience of the entire air conditioner 100.

[0069] As for the connection between the heat exchanger 130 and the support base 140, they can be connected by screws. A screw can be driven into each end of the heat exchanger 130 along the width direction Y of the shell 110 to fix the heat exchanger 130 to the support base 140.

[0070] Figure 7 This paper shows a partial structural diagram of the air conditioner 100 provided in an embodiment of this application. Figure 8 It shows Figure 7 A magnified view of a section at point B. (See image below.) Figure 7 and Figure 8 As shown, in some embodiments, the support member 134 includes a connecting portion 162 and a supporting portion 164, the supporting portion 164 being connected to the connecting portion 162, and the heat exchanger 130 having a slot 132, in which the supporting portion 164 engages with the slot 132 when the heat exchanger 130 is separated from the support base 140.

[0071] It should be noted that, along the length X of the shell 110, both ends of the heat exchanger 130 are mounted on the shell 110 via support seats 140. The separation of the heat exchanger 130 from the support seats 140 mentioned in this application can mean that the heat exchanger 130 is separated from one of the support seats 140, or that the heat exchanger 130 is separated from both support seats 140. In this embodiment, the separation of the uniform heat exchanger 130 from one of the support seats 140 is described in detail.

[0072] When the air conditioner 100 is installed on the ceiling of the room, the support part 164 is located below the support base 140. If the heat exchanger 130 is separated from the support base 140, the heat exchanger 130 will move downward a certain distance under the action of gravity. The support part 164 is located below the support base 140, so that when the support part 164 cooperates with the slot 132, the distance between the heat exchanger 130 and the fan assembly 150 will increase. This allows the gap between the heat exchanger 130 and the bearing 156 to meet the space required for maintenance personnel to disassemble the bearing 156, thereby facilitating the disassembly of the bearing 156, making it easier to inspect and maintain the entire fan assembly 150, reducing the difficulty of inspecting and maintaining the fan assembly 150, and improving the overall convenience of maintenance of the air conditioner 100.

[0073] The support part 164 engages with the slot 132. After the heat exchanger 130 is removed from the support base 140, the support part 164 can be directly inserted into the slot 132. Under the action of gravity, the support part 164 can hold the entire heat exchanger 130. There is no need to use other fasteners to fix the support part 134 and the heat exchanger 130, making the operation simple and convenient.

[0074] like Figure 6 As shown, the heat exchanger 130 may include a support member 134, a coil 136, and fins 138. The fins 138 pass through the coil 136, and the end of the coil 136 is inserted into the support member 134. A slot 132 may be provided on the support member 134. The support member 134 is detachably connected to the support base 140.

[0075] Since the support base 140 is located at one end of the heat exchanger 130, when the heat exchanger 130 is disconnected from the support base 140, the other part of the heat exchanger 130 is still fixed to the shell 110. The coil 136 and fins 138 give the heat exchanger 130 a certain deformation capacity, so that the end of the heat exchanger 130 fixed to the support base 140 can move downward a certain distance under the action of gravity without the heat exchanger 130 being damaged. This ensures that the heat exchanger 130 can work normally after the fan assembly 150 is overhauled.

[0076] In addition, since the heat exchanger 130 is inclinedly arranged inside the housing 110, in order to improve the stability of the engagement between the support part 164 and the slot 132, the support surface 165 that engages with the slot 132 can be inclined, so that the support surface 165 can basically fully engage with the inner wall of the slot 132, thereby increasing the contact area between the support part 164 and the slot 132 and thus improving the stability of the support part 164 in fixing the heat exchanger 130.

[0077] In some embodiments, the connecting part 162 is mounted on the support base 140. Since the end of the heat exchanger 130 is fixedly connected to the support base 140, by setting the connecting part 162 on the support base 140, after the heat exchanger 130 is separated from the support base 140, the support part 164 can be directly hung in the slot 132, which facilitates the positioning between the support part 164 and the slot 132.

[0078] In addition, since the support base 140 is fixed to the end of the heat exchanger 130, the slot 132 can be set at the end of the heat exchanger 130 along the length direction X of the shell 110. That is, the slot 132 and the support base 140 can be set at the same end of the shell 110. After the heat exchanger 130 is released from the support base 140, this end of the heat exchanger 130 can be fixed by the support member 134, so that both ends of the heat exchanger 130 are fixed, which can improve the stability of the heat exchanger 130 during the maintenance of the fan assembly 150 and reduce the risk of the heat exchanger 130 falling.

[0079] In some embodiments, the connecting part 162, the supporting part 164 and the supporting base 140 are integrally formed, which can reduce the assembly process during the assembly of the air conditioner 100. The connecting part 162, the supporting part 164 and the supporting base 140 can be assembled as a whole at one end of the housing 110, which is simple and convenient to operate.

[0080] The specific structure and location of the support base 140 have been described above. The following will describe in detail how to inspect and maintain the fan assembly 150. After the support part 164 is engaged with the slot 132, it provides operating space for disassembling the bearing part 156 and the driver 152. The specific disassembly and assembly of the bearing part 156 and the driver 152 are as follows.

[0081] Figure 9 An exploded view of a portion of the structure of the air conditioner 100 provided in an embodiment of this application is shown. Figure 10 A cross-sectional view of the air conditioner 100 provided in an embodiment of this application is shown from another perspective, such as... Figure 9 and Figure 10As shown, in some embodiments, the bearing component 156 includes a bearing housing 156a, a bearing cover 156c, and a connecting bearing 156b. The connecting bearing 156b connects two adjacent impellers 154. The bearing component 156 is detachably connected to the bearing housing 156a. The bearing cover 156c is disposed between the bearing housing 156a and the heat exchanger 130. In the case where the support member 134 supports the heat exchanger 130, the heat exchanger 130 and the bearing cover 156c are spaced apart.

[0082] There are multiple impellers 154. Two adjacent impellers 154 are connected by a connecting bearing 156b. The driver 152 can be connected to one of the impellers 154, so that the driver 152 can drive multiple impellers 154 to rotate, so that the air can enter the housing cavity 112 to exchange heat with the heat exchanger 130 and then be blown out from the air outlet 116.

[0083] Since part of the heat exchanger 130 is located between the bearing cover 156c and the panel assembly 122, when the panel assembly 122 and the chassis assembly 124 are disassembled, part of the bearing cover 156c is blocked by the heat exchanger 130 and cannot be exposed. The gap between the bearing cover 156c and the heat exchanger 130 is too small, making it impossible to remove the bearing cover 156c. After the heat exchanger 130 is engaged with the support member 134, the distance between the heat exchanger 130 and the bearing cover 156c increases, so the bearing cover 156c can be removed from the bearing seat 156a, allowing the connecting bearing 156b to be exposed, thereby enabling the entire fan assembly 150 to be disassembled.

[0084] Figure 11 It shows Figure 10 A magnified view of a section at point C. Figure 12 It shows Figure 10 A partial enlarged view at point D. Regarding the connection method between the bearing cover 156c and the bearing seat 156a, the bearing cover 156c may have a first snap-fit ​​portion 1561c and a first fixing portion 1562c at both ends, and the bearing seat 156a may have a second snap-fit ​​portion 1561a and a second fixing portion 1562a at both ends. The first snap-fit ​​portion 1561c snaps into the second snap-fit ​​portion 1561a, and the first fixing portion 1562c is fixedly connected to the second fixing portion 1562a.

[0085] The first fixing part 1562c and the second fixing part 1562a are fixedly connected. Specifically, the connection can be achieved by using screws. The first snap-fit ​​part 1561c and the second snap-fit ​​part 1561a are engaged. During disassembly, the screws on the first fixing part 1562c and the second fixing part 1562a can be removed, and by separating the first snap-fit ​​part 1561c and the second snap-fit ​​part 1561a, the bearing cover 156c can be removed from the bearing seat 156a. This connection method allows for the removal or installation of the bearing cover 156c by simply removing one screw, making the operation simple and convenient.

[0086] In some embodiments, along the height direction Z of the housing 110, the projection of the first snap-fit ​​portion 1561c on the housing 110 overlaps with the projection of the heat exchanger 130 on the housing 110; the projection of the first fixing portion 1562c on the housing 110 is offset from the projection of the heat exchanger 130 on the housing 110. This indicates that the first snap-fit ​​portion 1561c is blocked by the heat exchanger 130, while the first fixing portion 1562c is not blocked by the heat exchanger 130. Screws are driven into the first fixing portion 1562c and the second fixing portion 1562a, and the first snap-fit ​​portion 1561c and the second snap-fit ​​portion 1561a only snap together. That is, the screw positions are not blocked by the heat exchanger 130. This arrangement allows the screw positions to be exposed after the panel assembly 122 and the chassis assembly 124 are disassembled, facilitating maintenance personnel operation.

[0087] Because the first locking part 1561c and the second locking part 1561a are locked together, after the first fixing part 1562c and the second fixing part 1562a are separated, the bearing part 156 can be rotated to separate the first locking part 1561c and the second locking part 1561a. Maintenance personnel do not need to reach into the first locking part 1561c and the second locking part 1561a to separate them. The space for separating the first locking part 1561c and the second locking part 1561a is relatively small, so the distance that the heat exchanger 130 descends can be smaller, which can reduce the distance of deformation of the heat exchanger 130 and reduce the possibility that the deformation of the heat exchanger 130 cannot be recovered.

[0088] In some embodiments, the first snap-fit ​​portion 1561c is disposed on the side of the heat exchanger 130 away from the panel assembly 122, and when the heat exchanger 130 is supported by the support member 134, the first snap-fit ​​portion 1561c is spaced apart from the heat exchanger 130.

[0089] Along the height direction Z of the housing 110, the second snap-fit ​​portion 1561a is disposed above the first snap-fit ​​portion 1561c, and the first snap-fit ​​portion 1561c is disposed above the heat exchanger 130. The heat exchanger 130 is disposed above the chassis assembly 124 and the panel assembly 122. With the support member 134 supporting the heat exchanger 130 (the support portion 164 is snapped into the slot 132), the first snap-fit ​​portion 1561c is spaced apart from the heat exchanger 130, and there is a certain distance between the bearing cover 156c and the heat exchanger 130, which can provide a certain space for the rotation of the bearing cover 156c, so that the first snap-fit ​​portion 1561c and the second snap-fit ​​portion 1561a can be separated, and the entire bearing cover 156c can be disassembled.

[0090] In addition to removing the bearing cover 156c, the driver 152 also needs to be removed for maintenance of the fan assembly 150. The following will describe how to remove and install the driver 152.

[0091] Figure 13 An exploded view of the fan assembly 150 of the air conditioner 100 provided in an embodiment of this application is shown. In some embodiments, the housing 110 is provided with a mounting base 170, and the driver 152 and part of the impeller 154 are mounted on the mounting base 170; the air conditioner 100 also includes a motor cover 180 and an impeller cover 190 connected to the motor cover 180. The motor cover 180 covers the driver 152, and the impeller cover 190 covers the connection between the impeller 154 and the driver 152. The motor cover 180 and the impeller cover 190 are detachably connected to the mounting base 170.

[0092] The mounting base 170 is located at one end of the housing 110 along the length X direction. The portion of the driver 152 and the impeller 154 connected to the driver 152 can be installed inside the mounting base 170. The impeller cover 190 covers the connection between the impeller 154 and the driver 152, providing protection and fixation for the connection. Similarly, the motor cover 180 covers the driver 152. When the air conditioner 100 is in operation, the motor cover 180 is located below the driver 152, providing support and fixation for the driver 152.

[0093] In some embodiments, along the width direction Y of the housing 110, the support member 134 and the driver 152 are respectively disposed at both ends of the housing 110. The support member 134 and the driver 152 are respectively disposed at both ends of the housing 110 along the length direction X, which facilitates the layout of the support member 134 and the assembly and disassembly of the fan assembly 150.

[0094] The motor cover 180 and the impeller 154 cover are integrally formed. Since they are integrally formed, only the motor cover 180 and the impeller 154 cover need to be disassembled as a whole during assembly or disassembly. Disassembly or assembly only needs to be done once, making the operation simple and convenient.

[0095] Figure 14 This is a first-view structural schematic diagram of the mounting base 170 of the air conditioner 100 provided in an embodiment of this application. Figure 15 This paper shows a first-view structural schematic diagram of the motor cover 180 of the air conditioner 100 provided in an embodiment of this application, as shown in the figure. Figure 14 and Figure 15 As shown, regarding the assembly method of the motor cover 180, the impeller 154 cover and the mounting base 170, the motor cover 180 or the impeller 154 cover may be provided with a first connecting part 181, and the mounting base 170 may be provided with a second connecting part 171. The first connecting part 181 and the second connecting part 171 are detachably connected. Along the height direction Z of the housing 110, the projection of the first connecting part 181 on the housing 110 is offset from the projection of the heat exchanger 130 on the housing 110.

[0096] The first connecting part 181 and the second connecting part 171 can be detachably connected by screws. If it is necessary to remove the motor cover 180 and the impeller 154 cover as a whole from the mounting base 170, the screws can be loosened first. After the screws are removed, the first connecting part 181 and the second connecting part 171 can be separated, so that the motor cover 180 and the impeller 154 cover can be removed from the mounting base 170.

[0097] Along the width direction Y of the housing 110, a first connecting part 181 is provided at the end of the motor cover 180 away from the heat exchanger 130. A plug-in part 182 can be provided at the end of the motor cover 180 near the heat exchanger 130. A slot 172 can be provided on the mounting base 170. The plug-in part 182 can be inserted into the slot 172. When the air conditioner 100 is in use, the slot 172 is located above the heat exchanger 130. The heat exchanger 130 covers part of the slot 172. Through the cooperation between the plug-in part 182 and the slot 172, maintenance personnel can insert the plug-in part 182 into the slot 172 without having to reach under the heat exchanger 130, thus reducing the difficulty of disassembling and assembling the motor cover 180.

[0098] Figure 16 A structural schematic diagram of a portion of the air conditioner 100 is shown, as follows: Figure 16 As shown, in some embodiments, the motor cover 180 is provided with a groove 183 to avoid the coil 136 of the heat exchanger 130. Since part of the motor cover 180 is obscured by the heat exchanger 130, as... Figure 16As shown at W2, in order to reduce interference with the coil 136 of the heat exchanger 130 during the disassembly and assembly of the motor cover 180, a groove 183 can be provided on the motor cover 180 to avoid the heat exchanger 130, thereby reducing the possibility of interference with the coil 136 during the disassembly and assembly process.

[0099] Figure 17 This is a structural schematic diagram of the mounting base 170 of the air conditioner 100 provided in an embodiment of this application from a second perspective. Figure 18 This paper shows a second-view structural schematic diagram of the motor cover 180 of the air conditioner 100 provided in an embodiment of this application, as shown in the figure. Figure 17 and Figure 18 As shown, in some embodiments, the mounting base 170 has a first mounting groove 174, in which the driver 152 is mounted. The sidewall of the first mounting groove 174 has a guide surface 174a. Along the width direction Y of the housing 110, the guide surface 174a is disposed on the sidewall of the first mounting groove 174 away from the heat exchanger 130. When the motor cover 180 and the impeller cover 190 are removed from the mounting base 170, the guide surface 174a can guide the driver 152, allowing the entire fan assembly 150 to be disassembled away from the heat exchanger 130 in the width direction Y of the housing 110, thus allowing the fan assembly 150 to be removed from the housing 110.

[0100] The guide surface 174a can be tilted away from the heat exchanger 130. During disassembly, the driver 152 can slide outward along the guide surface 174a, making it easier for maintenance personnel to disassemble the fan assembly 150.

[0101] In some embodiments, the mounting base 170 has a second mounting groove 175, a portion of the impeller 154 is disposed in the second mounting groove 175, a clearance groove 175a is provided on the side wall of the second mounting groove 175, and the impeller cover 190 is provided with a mounting portion 192 disposed within the clearance groove 175a. The outer diameter of the impeller 154 is slightly larger than the outer diameter of the driver 152. The clearance groove 175a on the side wall of the second mounting groove 175 facilitates the assembly and disassembly of the impeller 154.

[0102] Specifically, the clearance groove 175a can be provided on the side of the second mounting groove 175 away from the heat exchanger 130 along the width direction Y of the housing 110.

[0103] Along the width direction Y of the housing 110, the impeller cover 190 has a clearance surface 193 on the side away from the mounting part 192, which reduces the possibility of interference between the impeller cover 190 and the impeller 154 during the installation of the impeller cover 190 and the motor cover 180.

[0104] When disassembling the motor cover 180 and the impeller cover 190 as a whole, first remove the screws from the first connecting part 181 and the second connecting part 171. Then, using the insertion part 182 as a support point, rotate the entire motor cover 180 towards the side closer to the heat exchanger 130. The rotation direction is as follows: Figure 18 As indicated by the middle arrow, the mounting part 192 is disengaged from the relief groove 175a, and the insertion part 182 is finally pulled out from the slot 172, thus removing the motor cover 180 and the impeller cover 190 as a whole.

[0105] The working principle of the air conditioner 100 provided in this application embodiment is as follows: In this application embodiment, the air conditioner 100 is installed on the top surface of the room, and the panel assembly 122 is at the bottom of the entire air conditioner. If the fan assembly 150 needs to be repaired, the panel assembly 122 and the chassis assembly 124 can be removed from the housing 110 first. Loosen the screws fixing the heat exchanger 130 and the support 140 so that the end of the heat exchanger 130 is hung on the support 164. Then loosen the screws of the first fixing part 1562c and the second fixing part 1562a and remove the bearing cover 156c from the bearing seat 156a. Then loosen the screws of the first connecting part 181 and the second connecting part 171 and rotate the motor cover 180 towards the heat exchanger 130 so that the motor cover 180 is removed from the motor seat. Then the fan wheel 154, the driver 152 and the connecting bearing 156b are removed from the housing 110 as a whole.

[0106] Conversely, after the fan assembly 150 has been overhauled, first place the impeller 154, driver 152, and connecting bearing 156b as a whole inside the housing 110. Place the connecting bearing 156b on the bearing seat 156a, place the driver 152 on the motor mount, then install the motor cover 180 onto the motor mount, and install the bearing 156 onto the bearing seat 156a, screwing it in. Next, lift the heat exchanger 130 upwards and place it on the mounting base 170 and support base 140. Finally, assemble the chassis assembly 124 and the panel assembly 122.

[0107] In summary, if the air conditioner 100 provided in this application requires maintenance of the fan assembly 150, the panel assembly 122 and the chassis assembly 124 can be removed from the housing 110 first. Then, the connection between the heat exchanger 130 and the support base 140 can be disconnected, and the heat exchanger 130 can be hung under the support member 134. The support member 134 can support the heat exchanger 130. The heat exchanger 130 and the bearing member 156 are spaced apart. Maintenance personnel can directly remove the bearing member 156 from the gap between the heat exchanger 130 and the fan assembly 150, thereby allowing the entire fan assembly 150 to be removed from the housing 110 for maintenance. In this embodiment, the fan assembly 150 can be repaired without removing the heat exchanger 130 from the housing 110. This operation method simplifies the repair steps of the fan assembly 150, reduces the repair difficulty of the fan assembly 150, and improves the repair convenience of the entire air conditioner 100.
