[0002] Common ceiling-mounted electrical appliances include devices such as air conditioners, bathroom heaters, fresh air fans, and exhaust fans. Ceiling-mounted electrical appliances usually consist of structures such as a box body, a duct assembly disposed inside the box body, and a fan assembly. Among them, the performance of ceiling-mounted electrical appliances is mainly affected by the size and volume of the fan assembly and the duct assembly inside the box body.

[0003] For example, a bathroom heater is a common indoor heating device, and its main function is to increase the temperature of the bathroom by electrically heating the air. A bathroom heater usually consists of a box body, a fan, a heater, etc. Among them, the performance such as the air volume of the bathroom heater is mainly affected by the size of the fan inside the box body. In the prior art, the installation method of installing the bathroom heater after installing the ceiling is usually adopted.

[0035] Now, the exemplary implementation manners according to the present application will be described in more detail with reference to the drawings. However, these exemplary implementation manners can be implemented in many different forms and should not be construed as being limited only to the implementation manners set forth herein. It should be understood that these implementation manners are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary implementation manners is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their descriptions will be omitted.

[0036] Combined with Figures 1 to 7 As shown, according to a specific embodiment of the present application, a fan assembly is provided.

[0037] Specifically, as shown in Figure 1 、 Figure 2 As shown, the fan assembly includes a blade assembly and a driving part. The blade assembly includes at least one impeller 30. The impeller 30 includes a plurality of impeller splicing bodies 31. Along the radial direction of the impeller 30, at least one of the plurality of impeller splicing bodies 31 is detachably connected to at least one of the remaining impeller splicing bodies 31, so that the plurality of impeller splicing bodies 31 have an assembly position when connected, and at least one of the plurality of impeller splicing bodies 31 has a disassembly position when separated from the remaining impeller splicing bodies 31. Among them, each impeller splicing body 31 is provided with blades 300; when the plurality of impeller splicing bodies 31 are in the assembly position, the output end of the driving part is connected to the impeller 30 and drives the plurality of impellers 30 to rotate.

[0038] Applying the technical solution of this embodiment, the plurality of impeller splicing bodies 31 are detachably connected to each other along the radial direction of the impeller 30. When the impeller splicing bodies 31 are spliced together and in the assembly position, a complete impeller 30 is formed. The driving part drives the impeller 30 to rotate so that the fan assembly can operate normally. When the impeller splicing bodies 31 are separated from each other and in the disassembly position, each impeller splicing body 31 can be disassembled together with the fan assembly. Since the size of each impeller splicing body 31 is smaller than that of the overall blade assembly, when installing the fan assembly, the impeller 30 can be installed more flexibly and conveniently, and the blade assembly and the driving part can be combined and installed more conveniently. At the same time, the disassembly and maintenance of each component can be made more convenient. When applied to a ceiling appliance, the impeller splicing bodies 31 can be respectively passed through a narrow installation opening and then assembled into a complete impeller 30 in the ceiling space to realize the normal operation of the fan assembly and the normal air outlet of the ceiling appliance. This installation method can make the size of the finally formed impeller 30 larger, improve the air outlet performance of the fan assembly, and further improve the air outlet performance of the ceiling appliance.

[0039] In this embodiment, the blade assembly includes one impeller 30. The impeller 30 includes two impeller splicing bodies 31. The two impeller splicing bodies 31 are detachably connected. One of the impeller splicing bodies 31 can be fixed to the driving part or the housing, that is, the installation of one of the impeller splicing bodies 31 is simplified. Just connect the other impeller splicing body 31 to it to switch the plurality of impeller splicing bodies 31 to the assembly position and complete the installation of the blade assembly.

[0040] In this embodiment, along the radial direction of the impeller 30, at least one of the multiple impeller segments 31 is detachably connected to at least one of the remaining impeller segments 31. It should be understood that the impeller 30 is cut into at least two impeller segments 31, and the cutting direction is the radial direction of the impeller 30. Moreover, the cutting plane can pass through the central axis of the impeller 30 or can be at a certain distance from the central axis of the impeller 30. Specifically, the impeller 30 has multiple assembly methods. For example, when assembling adjacent impeller segments 31, one impeller segment 31 moves along the radial direction of the impeller 30 towards another impeller segment 31 until it is connected to the other impeller segment 31. When disassembling adjacent impeller segments 31, one impeller segment 31 moves along the radial direction of the impeller 30 until it is completely separated from the other impeller segment 31. Or, when assembling adjacent impeller segments 31, one impeller segment 31 moves along the axial direction of the impeller 30 towards another impeller segment 31 until it is connected to the other impeller segment 31. When disassembling adjacent impeller segments 31, one impeller segment 31 moves along the axial direction of the impeller 30 until it is completely separated from the other impeller segment 31.

[0041] It should be noted that the blade assembly may also include multiple impellers 30. The multiple impellers 30 can be arranged adjacent to each other along the axial direction of the impeller 30. Each impeller 30 can also include more than two impeller segments 31. For example, the impeller 30 includes three impeller segments 31, and each impeller segment 31 occupies 1 / 3 of the size of the impeller 30. At least one of the impeller segments 31 can be fixedly connected to at least one of the driving part or the housing. Alternatively, the three impeller segments 31 can all be detachably arranged. In this way, the installation method of the impeller 30 can be selected according to the specific installation space between the blade assembly and the driving part, so as to facilitate the installation of the fan assembly in a smaller space without affecting the performance of the fan assembly.

[0042] Specifically, as Figure 1 , Figure 2 shown, in at least one of the two connected impeller segments 31, at least one limiting structure 40 is provided, and the two connected impeller segments 31 are detachably connected through the limiting structure 40. In this embodiment, the impeller 30 has two impeller segments 31, and the two impeller segments 31 are connected and assembled along the circumferential direction of the impeller 30. The connection between the two impeller segments 31 is detachably connected through a limiting structure 40. In this embodiment, the setting of the limiting structure 40 can ensure the stable connection of adjacent two impeller segments 31 and improve the air outlet stability of the fan assembly.

[0043] Further, the limiting structure 40 includes a first limiting structure 41 and a second limiting structure 42. Among the two connected impeller splicing bodies 31, the first limiting structure 41 is provided on one of the impeller splicing bodies 31, and the second limiting structure 42 is provided on the other impeller splicing body 31. When the two impeller splicing bodies 31 are connected, the first limiting structure 41 is connected to the second limiting structure 42. As Figure 1 shown, by connecting the first limiting structure 41 on one impeller splicing body 31 to the second limiting structure 42 on the other impeller splicing body 31, the connection stability in the circumferential direction of two adjacent impeller splicing bodies 31 can be ensured, and the circumferential runout and misalignment can be reduced.

[0044] In a preferred embodiment of the present application, when the two impeller splicing bodies 31 are connected, at least a part of the first limiting structure 41 extends into the second limiting structure 42 to ensure the connection stability of two adjacent impeller splicing bodies 31 and reduce the runout and misalignment in the radial direction.

[0045] Optionally, the second limiting structure 42 is any one of a limiting post, a limiting groove, and a limiting hole. The second limiting structure 42 includes but is not limited to a limiting post, a limiting groove, and a limiting hole, and any detachable and transmission structure can be set as the second limiting structure 42. Optionally, the first limiting structure 41 is any one of a limiting post and a limiting protrusion. The first limiting structure 41 is a structure that cooperates with the second limiting structure 42, and one of the first limiting structure 41 and the second limiting structure 42 is a groove or a hole structure, and the other is a protrusion or a columnar structure.

[0046] It should be noted that the first limiting structure 41 and the second limiting structure 42 can also be set as other structures that cooperate with each other. For example, the first limiting structure 41 and the second limiting structure 42 can adopt structures such as a buckle, a magnetic attraction, and a flanging to achieve detachable connection and transmission.

[0047] Further, when the two impeller splicing bodies 31 are connected, at least a part of the first limiting structure 41 extends into the second limiting structure 42. Since two adjacent impeller splicing bodies 31 are assembled by splicing with each other along the circumferential direction of the impeller 30, when the driving part drives the impeller 30 to rotate, a centrifugal force will be generated along the circumferential direction of the impeller 30. At this time, if the first limiting structure 41 and the second limiting structure 42 are set to extend and connect with each other along the axial direction of the impeller splicing body 31, a pressing force will be generated between the first limiting structure 41 and the second limiting structure 42, making the connection between the first limiting structure 41 and the second limiting structure 42 firm and stable, and not easily falling off from each other.

[0048] Preferably, at least a part of the first limiting structure 41 extends into the second limiting structure 42 along the axial direction of the impeller splicing body 31.

[0049] Further, the impeller splicing body 31 includes a hub 311. The hub 311 is provided with a driving mating portion 3110 that mates with the output end of the driving portion. When two adjacent impeller splicing bodies 31 are connected, the output end of the driving portion is connected to the driving mating portions 3110 of the two impeller splicing bodies 31 to drive the two impeller splicing bodies 31 to rotate simultaneously. As Figure 1 , Figure 2 shown, the hubs 311 of two adjacent impeller splicing bodies 31 are connected to each other, and the driving mating portions 3110 of the adjacent two hubs are connected and assembled in cooperation with each other. Then, the driving mating portion 3110 is connected to the power output end of the driving portion. In this way, when the driving portion drives the two impeller splicing bodies 31 to rotate, it will also drive the blades 300 on the impeller splicing bodies 31 to rotate to generate air volume. In this way, the connection stability of the impeller 30 can be further enhanced through the mutual cooperation of the driving mating portions 3110 of two adjacent impeller splicing bodies 31, and at the same time, the stability of the blade assembly when the blades 300 rotate is also enhanced.

[0050] Specifically, the impeller splicing body 31 includes a support unit 312 extending along the circumferential direction of the impeller 30. Along the axial direction of the impeller splicing body 31, the support unit 312 is arranged at a distance from the hub 311. One end of the blade 300 is connected to the hub 311, and the other end of the blade 300 is connected to the support unit 312. At least two limiting structures 40 are arranged on the impeller splicing body 31. One limiting structure 40 is arranged on the hub 311, and the other limiting structure 40 is arranged on the support unit 312. In this way, limiting structures 40 are arranged at both the hub 311 part and the support unit 312 part where two adjacent impeller splicing bodies 31 are connected, which can ensure the stable connection of the impeller splicing body 31 in the radial direction and avoid the damage of the blades 300 or the impeller splicing body 31 caused by the separation or misalignment of the support unit 312 end and the hub 311 end due to centrifugal force.

[0051] Further, the driving mating portion 3110 and the limiting structure 40 are both arranged close to the splicing position of the impeller splicing body 31. This can facilitate the connection and assembly of two adjacent impeller splicing bodies 31. As Figure 1 , Figure 2 shown, the driving mating portions 3110 of two adjacent impeller splicing bodies 31 are connected in cooperation through a card slot or a card cover, etc., and can also be fixedly connected to the driving portion by screwing, etc., which can also enhance the stability of the impeller 30.

[0052] Combined with Figures 1 to 7 shown, according to another specific embodiment of the present application, a ceiling electrical appliance is further provided. The ceiling electrical appliance has a fan assembly, and the fan assembly is the fan assembly in the above embodiment. The ceiling electrical appliance includes, but is not limited to, air outlet devices such as kitchen air conditioners, non-kitchen air conditioners, ceiling heaters, fresh air fans, etc.

[0053] When the housing assembly in the above embodiments is applied to a ceiling-mounted electrical appliance, since the blower assembly adopts a detachable composition method in which the impeller 30 is assembled by a plurality of impeller splicing bodies 31, the relatively large-sized impeller 30 can be divided into a plurality of relatively small-sized impeller splicing bodies 31. First, the impeller 30 is disassembled, and then the impeller 30 is assembled after entering the installation space. This can achieve the prior installation of the blower assembly in a relatively small space or when the housing assembly is not easily detachable, thereby making more reasonable use of the internal space of the housing assembly and facilitating the ceiling-mounted electrical appliance to pass through the ceiling installation opening, making the ceiling-mounted electrical appliance more suitable for environments with higher air volume requirements and improving the practicability and performance of the ceiling-mounted electrical appliance.

[0054] Further, as Figures 3 to 5 shown, the ceiling-mounted electrical appliance further includes a housing, the housing has an air duct 11, and the air duct 11 at least includes a volute air duct 111. A blower assembly is arranged in the volute air duct 111; wherein, the housing includes a housing main body 10 and a splicing housing 20. The housing main body 10 and the splicing housing 20 are detachably arranged along the radial direction of the blower assembly. When the housing main body 10 is connected to the splicing housing 20, the housing main body 10 and the splicing housing 20 jointly enclose the air duct 11.

[0055] Applying the technical solution of this embodiment, the blower assembly is arranged in the volute air duct 111, and the air volume generated by the blower assembly flows through the volute air duct 111. The housing main body 10 and the splicing housing 20 are detachably arranged along the radial direction of the blower assembly, and the splicing housing 20 and the housing main body 10 jointly enclose the air duct 11, that is, the capacity space of the volute air duct 111 is increased by the splicing housing 20, thereby improving the air outlet performance of the blower. At the same time, due to the detachable connection between the splicing housing 20 and the housing main body 10, when installing the blower assembly in the air duct 11, the splicing housing 20 can be disassembled first, and then the housing assembly can be installed after installing the blower assembly, which can more conveniently and quickly achieve the installation of components in a relatively small space.

[0056] It should be understood that in this embodiment, after the blower assembly is arranged in the volute air duct 111, the volute air duct 111 and the blower assembly jointly form the blower structure of the ceiling-mounted electrical appliance.

[0057] It should be noted that as Figure 6 、 Figure 7As shown, the detachable connection between the housing main body 10 and the splicing housing 20 only realizes convenient installation in the length and width directions of the ceiling-mounted electrical appliance. To achieve convenient installation in the thickness direction of the ceiling-mounted electrical appliance, the impeller 30 in the fan assembly can also be set in a detachable assembly manner. For example, the impeller 30 in the foregoing embodiment is set to include a plurality of impeller splicing bodies 31, and the plurality of impeller splicing bodies 31 are detachably connected to form the impeller 30. Then, part of the impeller splicing bodies 31 are set to be connected to the housing main body 10, and the other part of the impeller splicing bodies 31 are detachably arranged together with the splicing housing 20, so as to facilitate the impeller splicing bodies 31 to be placed in the housing main body 10 and then assembled, realizing the convenient installation of the entire fan assembly and housing assembly of the ceiling-mounted electrical appliance.

[0058] Specifically, as Figure 3 shown, the air duct 11 includes two volute air ducts 111 and a connecting air duct 112 for connecting the two volute air ducts 111. Along the radial direction of the volute air duct 111, the geometric centers of the two volute air ducts 111 are arranged with a distance. At least one fan assembly is arranged in each volute air duct 111. In this way, a relatively large capacity space can be provided in the air duct 11 part of the ceiling-mounted electrical appliance, thereby improving the air outlet performance of the housing assembly and meeting the user's requirement for large air volume air outlet.

[0059] Further, as Figure 3 、 Figure 4 shown, the housing is also provided with an air outlet 101 communicating with the air duct 11, and the air outlet direction of the air outlet 101 is arranged along the axial direction of the fan assembly. It should be noted that the axial direction of the impeller is the axial direction of the fan assembly. When installing the ceiling-mounted electrical appliance, after passing the housing main body 10, the splicing housing 20, the impeller splicing body 31 and other components through the installation opening and putting them into the ceiling space, the components are assembled to obtain a complete housing assembly, and the placement method of the housing assembly is adjusted. In this embodiment, the height direction of the housing assembly is set along the vertical direction, that is, the axial direction of the fan assembly is set along the vertical direction, and the air outlet 101 is aligned with the installation opening to realize the smooth air supply of the ceiling-mounted electrical appliance.

[0060] In an embodiment of the present application, the ceiling-mounted electrical appliance is a linear bathroom warmer, and the linear bathroom warmer has the fan assembly and the housing assembly in the foregoing embodiment. Optionally, as Figures 3 - 7 shown, the air duct 11 is formed by the housing main body 10 and the splicing housing 20. Of course, the housing main body 10 can also be the outer housing of the bathroom warmer main unit. Specifically, according to actual needs, a lamp body assembly can also be provided at the air outlet to realize the lighting function.

[0061] When applying the fan assembly and the housing assembly to a linear bathroom heater, the relatively large-sized impeller 30 is arranged on the fan assembly in the form of multiple impeller splicing bodies 31. The blades 300 of the relatively large-sized impeller 30 are also relatively large, which improves the single-machine air volume of the linear bathroom heater. Thus, a larger air output can be achieved without additionally installing a fan. The housing is disassembled into a housing main body 10 and a splicing housing 20 for assembly. While ensuring sufficient internal space of the housing for smoothly placing the fan assembly, the housing assembly can be smoothly installed from the ceiling installation opening, and the extremely narrow shape of the installation opening can be maintained simultaneously to meet the aesthetic standards of users.

[0062] For ease of description, spatial relative terms, such as "above", "on top of", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to another device or feature as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "on top of" another device or structure will then be oriented "below" or "beneath" the other device or structure. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0063] In addition to the above, it should also be noted that in this specification, the terms "one embodiment", "another embodiment", "embodiment", etc. refer to the specific features, structures, or characteristics described in connection with that embodiment being included in at least one embodiment generally described in this application.
