Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, and in particular to a fan assembly and a ceiling-mounted electrical appliance having the same. Background Art

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

[0003] For example, a bath heater is a common indoor heating device, and its main function is to increase the temperature of the bathroom by heating air. A bath heater usually consists of a box body, a fan, a heater, etc. Among them, the performance such as the air volume of a bath heater is mainly affected by the size of the fan inside the box body. In the prior art, the bath heater is usually installed after the ceiling is installed. In order to maintain aesthetics, especially for a linear bath heater, the installation opening is relatively narrow, so that a bath heater with a fan having a relatively large axial dimension in the prior art cannot pass through smoothly. If the installation opening is enlarged to achieve the smooth installation of the bath heater, the final aesthetic degree will be affected. If only a bath heater adapted to the installation opening is selected for installation, due to the limitation of the box body of the bath heater, the axial dimension of the fan is small, and the air outlet performance of the fan will also be affected.

[0004] In view of the above problems, no effective solution has been proposed yet. Summary of the Utility Model

[0005] The main object of the present utility model is to provide a fan assembly and a ceiling-mounted electrical appliance having the same, so as to solve the problem that the small size of the fan in the prior art limits the air supply performance.

[0042] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order different from those illustrated or described herein.

For example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0045] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments 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 description will be omitted.

[0046] Combined with Figures 1 to 11 As shown, according to a specific embodiment of the present application, a fan assembly is provided.

[0047] Specifically, as Figures 1 to 4 shown, the fan assembly includes a blade assembly and a driving part. The blade assembly includes a plurality of impeller structures 30. The plurality of impeller structures 30 are arranged in sequence along the axial direction of the impeller structure 30, and at least one impeller structure 30 is detachably connected to at least one of the remaining impeller structures 30. A plurality of blades 300 are arranged circumferentially on each impeller structure 30. The output end of the driving part is connected to at least one impeller structure 30. When the plurality of impeller structures 30 are connected, the driving part can drive the plurality of impeller structures 30 to rotate synchronously.

[0048] Applying the technical solution of this embodiment, multiple impeller structures 30 are arranged along the axial direction of the impeller structure 30. More blades 300 can be arranged on the multiple impeller structures 30. When the driving part drives the fan to rotate, the more blades 300 can generate a greater air volume. The fan assembly in this embodiment improves the air volume of the fan assembly by changing the number of impeller structures 30 in the axial direction and the overall axial dimension of the wind wheel assembly. When installing the ceiling electrical appliance and the fan assembly, the multiple impeller structures 30 of the wind blade assembly can be sequentially passed through the narrow installation opening separately, and then the multiple impeller structures 30 are assembled in the ceiling space. This can ensure the smooth installation of the fan assembly while increasing the air volume of the fan assembly. The technical solution of increasing or decreasing the number of impeller structures 30 and the axial dimension in the axial direction of the fan assembly in this embodiment, when applied to electrical appliance structures such as linear bathroom heaters, can select the number of impeller structures 30 to be installed according to the size and air supply requirements of the linear bathroom heater housing. While ensuring a very narrow and beautiful installation opening, the smooth installation of the linear bathroom heater is completed, and the air supply performance of the linear bathroom heater is improved.

[0049] It should be noted that when multiple impeller structures 30 are arranged adjacent to each other along the axial direction of the impeller structure 30, at least one end of one of the impeller structures 30 is connected to the output end of the driving part, and the other end of the impeller structure 30 is connected to the remaining impeller structures 30. When the driving part drives the impeller structure 30 to rotate, the driving part drives multiple impeller structures to rotate synchronously at the same time.

[0050] Furthermore, as Figure 2 、 Figure 4 shown, at least one impeller structure 30 is provided with a limiting structure 60, and the adjacent impeller structures 30 are detachably connected through the limiting structure 60. In this embodiment, the fan assembly has two impeller structures 30. Along the axial direction of the two impeller structures 30, the two impeller structures 30 are detachably connected through the limiting structure 60. A hub is provided on one of the impeller structures 30 and is connected to the driving part. The driving part is a motor, and the hub is connected to the output shaft of the motor. In this embodiment, the setting of the limiting structure 60 can ensure the stable connection of the adjacent two impeller structures 30 and improve the air supply stability of the fan assembly. In other embodiments, the number of impeller structures 30 can be three or more.

[0051] Specifically, the limiting structure 60 includes a first limiting structure 61 and a second limiting structure 62. The plurality of impeller structures 30 include an adjacent first impeller 31 and a second impeller 32. Either the first impeller 31 or the second impeller 32 is provided with the first limiting structure 61, and the other of the first impeller 31 and the second impeller 32 is provided with the second limiting structure 62. When the first impeller 31 and the second impeller 32 are connected, the second limiting structure 62 is connected to the first limiting structure 61. Such a setting realizes the stable connection of the first impeller 31 and the second impeller 32 through the matching structure of the first limiting structure 61 and the second limiting structure 62. Preferably, a part of the second limiting structure 62 extends into the first limiting structure 61. When the impeller structure 30 is driven to rotate by the driving part, torque transmission can be realized between the first limiting structure 61 and the second limiting structure 62, thereby driving the adjacent impeller structure 30 to rotate.

[0052] Optionally, as Figure 2 , 4 shown, the first limiting structure 61 is arranged on the blade 300 of one of the impeller structures 30 (i.e., the second impeller 32), and the second limiting structure 62 is arranged on the blade 300 of the adjacent impeller structure 30 (i.e., the first impeller 31). The second limiting structure 62 extends into the first limiting structure 61 along the axial direction of the impeller structure 30, so that two adjacent impeller structures 30 are connected.

[0053] Optionally, as Figure 2 shown, the first limiting structure 61 is arranged on the blade 300 of one of the impeller structures 30 (i.e., the second impeller 32), and the blade 300 of the other adjacent impeller structure 30 (i.e., the first impeller 31) extends into the first limiting structure 61 along the axial direction of the impeller structure 30, so that two adjacent impeller structures 30 are detachably connected through the first limiting structure 61 arranged on the blade 300, and the output end of the driving part drives the blades 300 of the first impeller 31 and the second impeller 32 to rotate together.

[0054] In this embodiment, by making a part of the blade 300 of the impeller structure 30 extend into the first limiting structure 61 of another impeller structure 30 along the axial direction, the connection stability in the radial direction of two adjacent impeller structures 30 can be ensured, and the radial runout and misalignment can be reduced.

[0055] It should be noted that the blades 300 are arranged along the circumferential direction of the impeller structure 30. As Figure 2 shown, the first limiting structure 61 can be arranged only on some of the blades 300, and the blades provided with the first limiting structure 61 are evenly distributed along the circumferential direction of the impeller structure 30. The blades 300 of another adjacent impeller structure 30 are arranged corresponding to the first limiting structure 61 one by one and are distributed along the circumferential direction of the impeller structure 30.

[0056] Preferably, in two adjacent impeller structures 30, a first limiting structure 61 is provided on the blade 300 of one of the impeller structures 30, and a part of the blade 300 of the other impeller structure 30 that is in fit connection with the first limiting structure 61 extends into the corresponding first limiting structure 61. In this way, while reducing the radial runout of the impeller structure 30, the quick positioning and installation of two adjacent impeller structures 30 can be realized.

[0057] Those skilled in the art should understand that the first limiting structure 61 can also be provided only on the impeller frame of the impeller structure 30, and the impeller frames of two adjacent impeller structures 30 are detachably connected through the first limiting structure 61. In some embodiments, the first limiting structure 61 is located between adjacent blades 300 of the first impeller 31 or the second impeller 32.

[0058] Furthermore, as Figure 1 shown, a plurality of first limiting structures 61 are provided on any one of the first impeller 31 and the second impeller 32, and the plurality of first limiting structures 61 are arranged at intervals along the circumferential direction of the impeller structure 30. The first impeller 31 and the second impeller 32 are arranged correspondingly. By providing a plurality of first limiting structures 61 arranged at intervals along the circumferential direction, when two adjacent impeller structures 30 are connected, the connection reliability and rotational stability of the impeller structure 30 and the blade 300 can be improved.

[0059] Specifically, the first limiting structure 61 is located between adjacent blades 300 of the first impeller 31 or the second impeller 32. The first limiting structure 61 can be provided on the first impeller 31 or the second impeller 32. When the first limiting structure 61 is provided on one of the impellers, a part of the blade 300 of the other impeller is provided with a structure that cooperates with the first limiting structure 61.

[0060] Optionally, the first limiting structure 61 is any one of a limiting groove, a limiting hole, and a limiting post. The first limiting structure 61 includes but is not limited to a limiting groove, a limiting hole, and a limiting post, and any detachable and transmission structure can be set as the first limiting structure.

[0061] It should be noted that the first limiting structure 61 can be provided at the end of the blade 300 or in the middle position of the blade 300. For example, a limiting groove is provided in the middle of some blades 300 of the first impeller 31. When the second impeller 32 is assembled with the first impeller, the side wall of the blade 300 of the second impeller 32 is in close contact with the blade 300 of the first impeller 31, so that the blade 300 of the second impeller 32 extends into the limiting groove on the blade 300 of the first impeller 31.

[0062] Optionally, the second limiting structure 62 is any one of a limiting protrusion and a limiting column. The second limiting structure 62 is a structure that matches the first limiting structure 61, for example, one of the first limiting structure 61 and the second limiting structure 62 is a groove or hole structure, and the other is a protrusion or columnar structure.

[0063] It should be understood that when the second limiting structure 62 is a limiting protrusion, a limiting column or other structures, the first limiting structure 61 and the second limiting structure 62 can be set on the blade 300 or on the hub of the impeller structure 30 .

[0064] Optionally, the second limiting structure 62 is a portion of the blade 300 or is disposed on the blade 300. In an exemplary embodiment of the present application, the first limiting structure 61 is disposed on any one of the first impeller 31 and the second impeller 32, and a portion of the portion of the blade 300 of the other of the first impeller 31 and the second impeller 32 extends along the axial direction of the impeller structure 30 and is connected to the first limiting structure 61.

[0065] It should be noted that the first limiting structure 61 and the second limiting structure 62 can also be set as other structures that cooperate with each other. For example, the first limiting structure 61 and the second limiting structure 62 can adopt structures such as snap-on, magnetic, and flanging to achieve detachable connection and transmission.

[0066] Furthermore, any one of the first impeller 31 and the second impeller 32 is provided with a first clamping piece, and the other of the first impeller 31 and the second impeller 32 is provided with a second clamping piece. The first clamping piece and the second clamping piece have a clamping state for clamping the first impeller 31 and the second impeller 32, and the first clamping piece and the second clamping piece have a releasing state for releasing the first impeller 31 and the second impeller 32. The provision of the first clamping member and the second clamping member can improve the reliability of the connection between the first impeller 31 and the second impeller 32, solve the axial runout problem between the first impeller 31 and the second impeller 32, and improve the connection reliability of the two adjacent impeller structures 30. When the first impeller 31 and the second impeller 32 are in a clamped state, the first limiting structure 61 and the second limiting structure 62 on the first impeller 31 and the second impeller 32 cooperate to connect the blades 300 of the two adjacent impeller structures 30. When the first impeller 31 and the second impeller 32 are in a released state, the two adjacent impeller structures 30 can be disassembled or installed.

[0067] Specifically, the first clamping member and the second clamping member can be various structures such as a buckle-and-slot structure, a claw-and-slot structure, a buckle-and-control structure, etc. that cooperate with each other.

[0068] Combination Figures 1 to 10As shown, according to another specific embodiment of the present application, a ceiling-mounted electrical appliance is provided. The ceiling-mounted electrical appliance has a fan assembly, and the fan assembly is the fan assembly in the above embodiment. The ceiling-mounted electrical appliance includes, but is not limited to, devices such as kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, fresh air fans, and exhaust fans.

[0069] When the fan assembly in the above embodiment is applied to a ceiling-mounted electrical appliance, since the fan assembly adopts a plurality of impeller structures 30, a relatively large number of blades 300 can be provided on the plurality of impeller structures 30, and the plurality of impeller structures 30 are arranged adjacent to each other in the axial direction of the impeller structure 30 so that the plurality of impeller structures 30 can be driven by the driving part of the same fan assembly. The blades 300 between the impellers of the plurality of impeller structures 30 are connected by a limiting structure, so that the overall area of the blades 300 is increased, thereby making the air outlet effect of the ceiling-mounted electrical appliance better, more suitable for environments with higher air volume requirements, and improving the air outlet performance and practicality of the ceiling-mounted electrical appliance.

[0070] Specifically, the ceiling-mounted electrical appliance includes a housing assembly. The housing assembly includes a housing 1. The housing 1 has an air duct 11. A fan assembly is arranged in the air duct 11. Among them, at least part of the air duct 11 protrudes outward from the housing 1 in the radial direction of the fan assembly. Such a setting can increase the flow area of the air duct 11 and improve the air volume and air outlet rate of the housing assembly.

[0071] Preferably, the housing 1 has an air duct 11. The air duct 11 includes a volute air duct 111. A fan assembly is arranged in the volute air duct 111. Among them, at least part of the volute air duct 111 protrudes outward from the housing 1 in the radial direction of the fan assembly. Such a setting can increase the flow area of the volute air duct 111, provide a larger accommodation space for the arrangement of the fan assembly, enable the radial dimension of the fan assembly to be increased, and thus improve the air outlet performance of the fan assembly.

[0072] In an exemplary embodiment of the present application, the air duct 11 includes a volute air duct 111 and a connecting air duct 112 communicating with the volute air duct 111. A fan assembly is arranged in the volute air duct 111. Among them, at least part of the volute air duct 111 protrudes outward from the housing 1 in the radial direction of the fan assembly. The fan assembly and the volute air duct 111 form the fan of the ceiling-mounted electrical appliance. Such a setting can increase the flow area of the volute air duct 111, provide a larger accommodation space for the arrangement of the fan assembly, enable the radial dimension of the fan to be increased, and thus improve the air outlet performance of the fan and the ceiling-mounted electrical appliance. At the same time, the increase in the flow area of the volute air duct 111 can also increase the air speed and air volume in the volute air duct 111. The setting of the connecting air duct 112 can realize the air flow guiding function of the volute air outlet.

[0073] Specifically, the volute air duct 111 includes an air duct body 1111 and a splicing air duct 1112. The air duct body 1111 has an opening 1110. The splicing air duct 1112 has an avoidance position away from the opening 1110, and the splicing air duct 1112 has a blocking position for blocking at least part of the opening 1110. When the splicing air duct 1112 is in the blocking position, at least part of the splicing air duct 1112 protrudes outward from the housing 1 in the radial direction of the fan assembly.

[0074] In this embodiment, when the splicing air duct 1112 is located at the avoidance position, the longitudinal space size of the housing assembly is not affected. When the splicing air duct 1112 is located at the blocking position, the splicing air duct 1112 blocks the opening 1110 and is connected to the housing 1, which can avoid the problem of performance degradation caused by air leakage of the housing. When applied to the electrical structure, it can effectively increase the air volume of the electrical appliance, adapt to the use environment with high requirements for air volume, improve the practicability of the electrical appliance, and solve the problems of insufficient air volume and low practicability of the electrical appliance in the prior art.

[0075] Furthermore, as Figure 1 shown, the housing 1 includes a first housing 10 and a second housing 40. Along the axial direction of the fan assembly, the second housing 40 is detachably connected to the first housing 10. When the first housing 10 is connected to the second housing 40, the first housing 10 and the second housing 40 jointly enclose an air duct 11. The first housing 10 and the second housing 40 are correspondingly and detachably arranged, which is convenient for installing the internal components of the housing 1. At the same time, it is also convenient for the housing or the ceiling-mounted electrical appliance to be installed into the ceiling space through the ceiling installation opening. It should be noted that the height direction of the housing 1 is the axial direction of the fan assembly.

[0076] The installation process of the ceiling-mounted electrical appliance in the above embodiment is as follows: First, the first housing 10 equipped with the impeller structure 30 and the driving part is passed through the installation opening and placed into the ceiling space. The installation direction is the radial direction of the impeller structure 30. Then, the remaining impeller structures 30 and the second housing 40 are successively passed through the installation opening and placed into the ceiling space. The installation direction is the radial direction of the impeller structure 30. The multiple impeller structures 30 are assembled in the ceiling space to form a complete fan assembly, and then the second housing 40 and the first housing 10 are assembled to obtain a complete housing assembly. After the installation is completed, the axial direction of the fan assembly is placed horizontally.

[0077] It should be noted that the installation process can be changed according to actual needs. For example, the remaining impeller structure 30 and the second housing 40 can also be passed through the installation opening first, and then the first housing 10 can be passed through the installation opening. Or, an impeller structure 30 can be connected and fixed to the second housing 40 first and then they can be passed through the installation opening together. After the first housing 10 and the second housing 40 are both placed in the installation opening, the housing assembly can be horizontally moved so that the air outlet of the housing assembly is aligned with the installation opening to ensure smooth air supply.

[0078] As Figure 1 、 Figure 5 、 Figure 6 As shown, in a preferred embodiment of the present application, the housing assembly further includes a damper structure 20. The air duct 11 includes at least two volute air ducts 111 and a connecting air duct 112. Both of the two volute air ducts 111 are communicated with the connecting air duct 112. The housing 1 is further provided with an air outlet 101 and a ventilation opening 102. Both the air outlet 101 and the ventilation opening 102 are communicated with the connecting air duct 112. Wherein, at least one fan assembly is arranged in each volute air duct 111; the damper structure 20 is arranged in the connecting air duct 112. The damper structure 20 has a first state and a second state. When the damper structure 20 is in the first state, the damper structure 20 opens the air outlet 101 to communicate with the fan air outlet and closes the ventilation opening 102 to communicate with the fan air outlet. When the damper structure 20 is in the second state, the damper structure 20 opens the ventilation opening 102 and communicates with the fan air outlet, and at the same time closes the air outlet 101 to block the communication with the fan air outlet.

[0079] Applying the technical solution of this embodiment, the volute air duct 111 is communicated with the connecting air duct 112, that is, the fan air outlet is communicated with the connecting air duct 112. At the same time, both the air outlet 101 and the ventilation opening 102 of the housing assembly are communicated with the connecting air duct 112. The air guided out by the volute air duct 111 can be discharged through the air outlet 101 or through the ventilation opening 102. On this basis, a damper structure 20 is arranged in the connecting air duct 112, and the damper structure 20 is respectively communicated with the air outlet 101 and the ventilation opening 102 by switching the position of the damper structure 20. When the damper structure 20 is in the first state, the damper structure 20 opens the air outlet 101 and closes the ventilation opening 102. At this time, the housing assembly performs blowing or warm air work. When the damper structure 20 is in the second state, the damper structure 20 opens the ventilation opening 102 and closes the air outlet 101. At this time, the housing assembly performs ventilation work. By switching the damper to switch the ventilation and blowing of the housing assembly, a primary fan and its accessory structure can be saved, the capacity space of the air duct 11 can be increased, the performance of the housing assembly can be improved, and the cost can be reduced.

[0080] In this embodiment, along the length direction of the housing assembly, the air duct 11 includes two volute air ducts 111 and two connecting air ducts 112. A blower assembly is disposed in each of the two volute air ducts 111. Each blower assembly includes a blade assembly and a driving part. By using two blower assemblies, that is, using two blowers to supply air or exhaust air to the room, the air volume output by the blower assembly can be increased. At the same time, due to the provision of the damper structure 20, the two blower assemblies can be used for ventilation operations by means of damper switching, that is, the setting of a ventilation blower assembly can be reduced, the space of the housing 1 can be saved, and the performance of the housing assembly can be improved.

[0081] Specifically, as Figure 1 shown, the housing 1 includes a first housing 10 and a second housing 40. Along the height direction of the housing 1, the second housing 40 is detachably connected to the first housing 10. When the first housing 10 is connected to the second housing 40, the first housing 10 and the second housing 40 jointly enclose the air duct 11. The first housing 10 and the second housing 40 are correspondingly and detachably arranged, which is convenient for installing the internal components of the housing 1. It should be noted that the height direction of the housing 1 is the axial direction of the blower assembly.

[0082] Further, the damper structure 20 and the driving part of the blower assembly are both disposed in the first housing 10. The air outlet 101 and the ventilation opening 102 are both formed in the first housing 10. The installation of the blower assembly can be realized through the detachable connection between the impeller structures 30, that is, the driving part is connected to one of the impeller structures 30, and the other impeller structure 30 is disposed in the second housing 40. After the components in the first housing 10 are installed, the first impeller 31 and the second impeller 32 are adjusted to the clamped state through the limiting structure 60, the first clamping member and the second clamping member to complete the installation of the blower assembly. At the same time, the connection reliability between the first housing 10 and the second housing 40 can also be improved.

[0083] Specifically, the damper structure includes a damper assembly 21 and a driving assembly 22. The damper assembly 21 includes at least one damper. The damper has a driving end and a movable end which are oppositely arranged, and the damper is rotatably arranged; the driving assembly 22 includes at least a driving member 222 and a flexible member 223. One end of the flexible member 223 is connected to the output shaft 2220 of the driving member 222, and the other end of the flexible member 223 is connected to the driving end. Wherein, when the output shaft 2220 rotates, the winding length of the flexible member 223 on the output shaft 2220 is adjusted, and further the distance between the driving end and the output shaft 2220 is adjusted, thereby driving the damper to rotate.

[0084] Preferably, the air door assembly 21 includes a first air door 211 and a second air door 212 that are rotatably connected. The first air door 211 has a first driving end 2111 and a first movable end 2112, and the second air door 212 has a second driving end 2121 and a second movable end 2122. One end of the flexible member 223 is connected to the output shaft 2220 of the driving member 222, and the other end of the flexible member 223 is connected to at least one of the first driving end 2111 and the second driving end 2121. Wherein, the output shaft 2220 rotates to adjust the winding length of the flexible member 223 on the output shaft 2220, and further adjust the distance between at least one of the first driving end 2111 and the second driving end 2121 and the output shaft 2220, so as to adjust the included angle between the first air door 211 and the second air door 212. By providing the first air door 211 and the second air door 212 that cooperate with each other, the shielding and diversion control of air flow in more directions can be realized, the adjustment range of the air door structure is increased, the control difficulty of a single air door is reduced, and the overall control efficiency of the air door structure is improved. The setting of the two air doors can also make the wind shielding and guiding effects better, and the change of the cooperation angle between the two air doors is beneficial to realizing various diversion modes of the air flow, improving the practicability of the air door structure.

[0085] Further, there are two flexible members 223. The first ends of the two flexible members 223 are both connected to the output shaft 2220 of the driving member 222. The second end of one flexible member 223 is connected to the first driving end 2111, and the second end of the other flexible member 223 is connected to the second driving end 2121. By using two flexible members 223 to control the first air door 211 and the second air door 212 respectively, the power control of the first air door 211 and the second air door 212 can be realized, and the adjustment freedom degree of the air door assembly 21 is higher.

[0086] Further, the air door structure further includes an elastic member 224. One end of the elastic member 224 is connected to the first driving end 2111, and the other end of the elastic member 224 is connected to the second driving end 2121. The setting of the elastic member 224 can enable the elastic member 224 to cooperate with the flexible member 223 to keep the first driving end 2111 and the second driving end 2121 in the current state after the first driving end 2111 and the second driving end 2121 move to the specified state, and it is not easy to swing, improving the state stability of the air door structure.

[0087] Preferably, the elastic member 224 is a torsion spring, and during the rotation of the air door, the elastic member 224 is always in a compressed state.

[0088] Further, both the first air damper 211 and the second air damper 212 are hinged to the air damper rotating shaft 221. The distance between the air damper rotating shaft 221 and the end of the first driving end 2111 is less than the distance between the air damper rotating shaft 221 and the end of the first movable end 2112. The distance between the air damper rotating shaft 221 and the end of the second driving end 2121 is less than the distance between the air damper rotating shaft 221 and the end of the second movable end 2122. Such a setting enables the driving member 222 to only drive the first driving end 2111 and the second driving end 2121 to rotate a small distance to achieve the position switching of the air damper assembly 21. This can simplify the connection between the air damper rotating shaft 221 and the driving member 222, reduce the requirements for the driving member 222, and reduce the cost of the air damper structure.

[0089] Preferably, there is one driving member 222, and the output shaft 2220 of the driving member 222 is connected to two flexible members 223. Using one driving member 222 to control two flexible members 223 simultaneously can reduce the cost of the air damper structure.

[0090] In this embodiment, when the output shaft 2220 of the driving member 222 rotates, the two flexible members 223 change synchronously around the output shaft 2220, so that both the first driving end 2111 and the second driving end 2121 move towards the output shaft 2220, or both the first driving end 2111 and the second driving end 2121 move away from the output shaft 2220.

[0091] Further, as Figure 1 shown, the air damper structure 20 further includes a shielding member 50. The shielding member 50 is disposed near the air exchange port 102, and the distance between the shielding member 50 and the bottom of the first housing 10 is greater than the maximum distance between the air exchange port 102 and the bottom of the first housing 10. The shielding member 50 is connected to at least one of the first housing 10, the air damper assembly 21, and the second housing 40. When the air damper assembly 21 is in the first state, the air damper assembly 21 and the shielding member 50 jointly block the air exchange port 102. In this embodiment, the setting of the shielding member 50 enables the shielding member 50, the air damper assembly 21, and the first housing 10 to jointly block the air exchange port 102 when the air damper structure 20 is in the first state. As Figure 3 shown, the shielding member 50 can prevent the airflow in the air duct 11 from entering the air exchange port 102 along the height direction of the housing 1. At this time, the air damper assembly 21 does not affect the cross-sectional area of the air duct 11, and can avoid affecting the air volume output of the fan and further affecting the performance of the housing assembly.

[0092] Specifically, as Figure 1As shown in the figure, the shielding member 50 includes a first shielding member 51. The first shielding member 51 extends along the width direction of the housing 1. The first end of the first shielding member 51 is connected to the first housing 10, and the second end of the first shielding member 51 is connected to the air door assembly 21. When the air door assembly 21 is in the first state, the first shielding member 51 extends along the width direction of the housing 1 and encloses a space with the air door assembly 21 and the first housing 10 with the ventilation opening 102 as the opening. The interior of the housing 1 is not connected to the ventilation opening 102. At this time, the housing assembly performs a blowing operation.

[0093] Optionally, as Figure 1 shown in the figure, the shielding member 50 further includes a second shielding member 52 disposed on the second housing 40. Along the width direction of the second housing 40, a mating groove 41 is formed on the outer peripheral surface of the second housing 40. Along the height direction of the second housing 40, the second shielding member 52 is disposed at one end of the mating groove 41 close to the first housing 10. When the air door assembly 21 is in the first state, the second shielding member 52 encloses a space with the air door assembly 21 and the first housing 10 with the ventilation opening 102 as the opening. The interior of the housing 1 is not connected to the ventilation opening 102. At this time, the housing assembly performs a blowing operation.

[0094] It should be noted that the first shielding member 51 and the second shielding member 52 can be selectively provided or provided simultaneously. When the first shielding member 51 and the second shielding member 52 are provided simultaneously, preferably, the second shielding member 52 and the first shielding member 51 are correspondingly provided on the second housing 40 and the first housing 10 respectively. When the first housing 10 is connected to the second housing 40 and the air door assembly 21 is in the first state, the first shielding member 51, the second shielding member 52 and the air door assembly 21 jointly block the ventilation opening 102.

[0095] Furthermore, at least one volute air duct 111 includes a duct body 1111 and a splicing air duct 1112. The duct body 1111 has an opening 1110. The splicing air duct 1112 has a blocking position for blocking at least part of the opening 1110, and the splicing air duct 1112 has an avoidance position for opening the opening 1110. When the splicing air duct 1112 is in the avoidance position, the longitudinal space size of the housing assembly is not affected. When the splicing air duct 1112 is in the blocking position, the splicing air duct 1112 blocks the opening 1110 and is connected to the housing 1, which can avoid the problem of performance degradation caused by air leakage of the housing. When applied to the electrical structure, it can effectively increase the air volume of the electrical appliance, adapt to the use environment with a large requirement for air volume, improve the practicability of the electrical appliance, and solve the problems of insufficient air volume and low practicability of the electrical appliance in the prior art.

[0096] Those skilled in the art should understand that when the splicing air duct 1112 is in the blocking position, the blocking position can block at least part of the opening 1110. Since the splicing air duct 1112 is already in this position, the capacity expansion of the air duct 11 is realized. When the housing assembly operates, the air volume output by the fan can be increased, improving the performance of the housing assembly. In this embodiment, the setting of the splicing air duct 1112 can increase the cross-sectional area of the air duct.

[0097] In one embodiment of the present application, two volute air ducts 111 are arranged along the length direction of the housing 1. Each volute air duct 111 includes an air duct body 1111 and a splicing air duct 1112. And, along the width direction of the housing 1, the splicing air ducts 1112 are located on the same side of the housing 1. The splicing air duct 1112 can be used to increase the capacity of the air duct 11, thereby increasing the air volume, improving the air volume output of the air duct 11 provided with the splicing air duct 1112, and further improving the air volume output and performance of the housing assembly.

[0098] Furthermore, the two volute air ducts 111 are arranged at a distance along the length direction of the housing 1. Along the width direction of the housing 1, the air outlet 101 and the ventilation opening 102 are respectively opened on opposite sides of the housing 1. Such a setting facilitates the switching of the damper assembly 21 between the first state and the second state, and facilitates the blocking or avoidance of the air outlet 101 and the ventilation opening 102.

[0099] Furthermore, a PTC heater 70 is also provided on one side of the first housing 10 close to the air outlet 101. The PTC heater 70 is arranged corresponding to the air outlet 101 along the height direction of the first housing 10. When the air outlet operation is performed, the air in the air duct 11 will be heated by the PTC heater 70 and then blown out from the air outlet 101, realizing the heating function of the housing assembly.

[0100] In one embodiment of the present application, the ceiling electric appliance is a linear bathroom warmer. The linear bathroom warmer has the fan assembly and the housing assembly in the foregoing embodiment. Optionally, as Figure 1 、 Figures 8 - 10 shown, the air duct 11 is independently formed by the housing 1. At this time, the housing 1 is the volute side plate, that is to say, at this time, the air duct structure is independently formed by the volute side plate. Of course, as Figure 5 and Figure 6 shown, the housing 1 can also be the outer housing of the bathroom warmer main unit. The air duct 11 can be independently formed by a volute side plate provided separately from the housing 1. The volute side plate can be set as a plate-shaped structure, and the air duct 11 is formed by enclosing between the side wall of the housing 1 and the bottom plate of the housing.

[0101] When applying the fan assembly and the housing assembly to a linear ceiling heater, the fan assembly includes a plurality of detachable impeller structures 30, which improves the single-machine air volume of the linear ceiling heater, so that a larger air output can be achieved without additionally installing a fan; the splicing air duct 1112 is protruded outward on the housing 1, which increases the air volume of the fan of the linear ceiling heater, making the air output effect of the ceiling heater better. And the linear ceiling heater is arranged with the air outlet 101 and the ventilation opening 102 opposite to each other, and the blocking and avoidance of the air outlet 101 and the ventilation opening 102 are realized through the air door structure 20. Furthermore, with two fans, while achieving a large air volume, the switching between the blowing and ventilation functions can also be realized, saving a primary fan and its accessory structures, achieving the effect of performance optimization and installation technology simplification in the technical field of ceiling heater equipment, improving the air output performance and practicality of the ceiling heater. At the same time, the extremely narrow shape of the linear ceiling heater is more beautiful, meeting the aesthetic standards of users.
