It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0039] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0040] Combination Figures 1 to 7 As shown, according to a specific embodiment of the present application, a shell assembly is provided.

[0041] Specifically, Figure 1 , Figure 2 As shown, the shell assembly includes a shell 10 and an electrical assembly 50, the shell 10 has a volute side plate 12 for forming an air duct 11, and the shell 10 has a first opening 101; the electrical assembly 50 is movably connected to the shell 10 through a motion mechanism so that the electrical assembly 50 has an initial position located inside the shell 10, and the electrical assembly 50 has an installation position located outside the shell 10.

[0042] By applying the technical solution of this embodiment, the shell 10 has a first opening 101, and the electrical component 50 moves through the motion mechanism and switches between the initial position and the installation position along the first opening 101. When the electrical component 50 is in the initial position, the electrical component 50 is stored in the shell 10, saving the overall space of the shell component, without increasing the external volume of the shell 10, which is beneficial to the transportation and installation of the shell component. When the electrical component 50 moves to the installation position, the electrical component 50 is located outside the shell 10 to avoid interference between the electrical component 50 and strong electricity. At the same time, the electrical component 50 does not occupy the internal space of the shell 10. A larger air duct 11 can be set inside the shell 10 to increase the air outlet of the shell component or provide a larger installation space for other components, thereby solving the problem of the electrical component interfering with strong electricity and occupying the internal space of the box in the prior art, improving the practicality of the shell component, and also solving the problem of the electrical component 50 interfering with external mounting parts or insufficient space size when it is located outside the shell 10 during installation.

[0043] It should be noted that the shell assembly in this embodiment is mainly used in ceiling appliances such as bathroom heaters. The size of the bathroom heater box directly affects the size of the fan and the volute, and thus affects the performance of the bathroom heater. In the traditional bathroom heater design, the size of the box is limited by the size of the ceiling gusset plate and the width of the keel, so that the size of the bathroom heater shell in the prior art has been maximized. If the air volume of the bathroom heater is increased by increasing the shell size, it is bound to cause the bathroom heater shell to be too large to be installed through the installation opening formed on the ceiling gusset plate (national standard structural part), or it cannot be installed through the keel formed on the ceiling gusset plate or the large plate. Based on the problems existing in the prior art, the air volume of the bathroom heater has always been at a low level, which cannot meet the use environment requiring a large air volume, making the practicality of the bathroom heater in the prior art not high. The shell assembly in this embodiment has two position states of the electrical component 50, namely the initial position and the installation position. When installing the bathroom heater, the electrical component 50 is placed in the initial position. At this time, the circumferential size of the shell assembly remains unchanged, and the shell assembly can pass through the installation port smoothly. After the shell assembly passes through the installation port, the electrical component 50 is moved to the installation position. At this time, the electrical component 50 is located outside the shell 10, avoiding the problem of strong electrical interference of the electrical component inside the shell 10 in the prior art, effectively improving the practicality of the bathroom heater device. In addition, since the final position of the electrical component 50 is outside the shell 10, there is more space inside the shell 10 to set the air duct, and the air output of the shell 10 is improved to meet the demand for larger air output.

[0044] Specifically, the electrical component 50 includes at least one of an electrical control panel component 30 and a junction box 60. Figures 1 to 3 , Figures 5 to 7 As shown, the electrical component 50 only includes the electric control board component 30, and the electric control board component 30 is movably connected to the housing 10 through a motion mechanism, such as Figure 4 As shown, the electrical component 50 only includes a junction box 60. The connection method of the junction box 60 and the housing 10 can refer to the connection method of the electric control board component 30 and the housing 10. Optionally, the electrical component 50 can also include both the electric control board component 30 and the junction box 60, that is, the electric control board component 30 and the junction box 60 are integrated. Among them, the electric control board component 30 is used to control various electrical devices in the housing 10. The electric control board component 30 includes control devices such as PCB boards. The junction box 60 is used to connect, protect, distribute, organize and fix the wires of various electrical devices in the housing 10. Generally, the junction box 60 includes structures such as a housing, a terminal block, and a wiring board.

[0045] Furthermore, if Figure 3-Figure 7As shown, the volute side plate 12 has a second opening 120, the motion mechanism includes a spliced ​​volute 20, the spliced ​​volute 20 is movably connected to the housing 10, the electrical component 50 is arranged on the spliced ​​volute 20, and the electrical component 50 can move to the initial position and the installation position with the spliced ​​volute 20; the spliced ​​volute 20 has a blocking position for blocking the second opening 120, and the spliced ​​volute 20 has a evasive position away from the second opening 120, and when the spliced ​​volute 20 is in the blocking position, the electrical component 50 is in the installation position. The electrical component 50 is arranged on the spliced ​​volute 20, and the position switching of the electrical component 50 can be realized while realizing the position switching of the spliced ​​volute 20, reducing the arrangement of the parts in the housing assembly, reducing the weight of the housing assembly and the number of parts, thereby making the structure of the housing assembly simpler and the manufacturing cost lower.

[0046] In this embodiment, when the spliced ​​volute 20 is in the blocking position, the spliced ​​volute 20 and the volute side plate 12 are jointly arranged to form an air duct 11. The setting of the spliced ​​volute 20 can increase the flow area of ​​the air duct 11, thereby increasing the air volume. Preferably, when the spliced ​​volute 20 is in the blocking position, the spliced ​​volute 20 seals the second opening 120 to avoid air leakage in the air duct. The electrical component 50 is located outside the shell 10 to avoid strong electrical interference between the shell component and the electrical component 50 during operation. When the spliced ​​volute 20 is in the avoidance position, the electrical component 50 is in the initial position, which can save the overall space of the shell component and facilitate the installation of the shell component.

[0047] Those skilled in the art should understand that the electrical component 50 is disposed on the spliced ​​volute 20, and the electrical component 50 moves with the movement of the spliced ​​volute 20. When the spliced ​​volute 20 is in the blocking position, the electrical component 50 is correspondingly in the installation position, and when the spliced ​​volute 20 is in the avoidance position, the electrical component 50 is correspondingly in the initial position. By switching the spliced ​​volute 20 between the avoidance position and the blocking position, the different usage requirements of customers can be met, that is, the requirements of avoiding strong electrical interference between the electrical component 50 and the shell assembly and expanding the air volume of the air duct 11 can be met at the same time, thereby improving the performance of the shell assembly.

[0048] Specifically, when the spliced ​​volute 20 is in the blocking position, at least part of the spliced ​​volute 20 is located outside the housing 10, so that the spliced ​​volute 20 and the volute side plate 12 are surrounded by a volute enclosure. This arrangement enables the spliced ​​volute 20 in the blocking position to expand the capacity of the air duct 11, thereby increasing the air volume of the housing assembly.

[0049] In this embodiment, when the spliced ​​volute 20 is located at the blocking position, at least a portion of the spliced ​​volute 20 is protruded from the outside of the first opening 101, so that the spliced ​​volute 20 and the volute side plate 12 are surrounded to form a volute enclosure.

[0050] Preferably, at least part of the profile of the spliced ​​volute 20 is arc-shaped along the length direction of the spliced ​​volute 20. The arc-shaped setting can reduce the resistance to air circulation, reduce the air volume loss during the air outlet process, and make the air flow more uniform. At the same time, the arc-shaped setting can also enhance the strength and stability of the spliced ​​volute 20 and reduce deformation and vibration.

[0051] Optionally, in one embodiment of the present application, Figure 2 As shown, when the spliced ​​volute 20 is in the blocked position, the spliced ​​volute 20 as a whole is still located in the shell 10, the electrical component 50 is connected to the spliced ​​volute 20 and is located outside the shell 10, and the volute enclosure formed by the spliced ​​volute 20 and the volute side panels 12 can be used to increase the capacity of the air duct 11, thereby increasing the air volume and improving the air output and performance of the shell assembly.

[0052] Furthermore, if Figure 1 As shown, when the spliced ​​volute 20 is in the avoidance position, the electrical component 50 and the spliced ​​volute 20 are both accommodated in the housing 10. This arrangement can reduce the longitudinal space of the entire housing assembly. Figure 2 As shown, when the spliced ​​volute 20 is in the blocking position, the electrical components 50 and the spliced ​​volute 20 are both located outside the housing 10. This can make the air duct 11 formed by the spliced ​​volute 20 and the volute side plate 12 have a larger capacity, increase the air volume, and improve the efficiency of air flow.

[0053] Optionally, in one embodiment of the present application, when the spliced ​​volute 20 is in the blocked position, part of the spliced ​​volute 20 is outside the shell 10, and the other part of the spliced ​​volute 20 is still inside the shell 10. The part of the spliced ​​volute 20 outside the shell 10 fills the first opening 101, and the part of the spliced ​​volute 20 inside the shell 10 abuts against the volute side plate 12.

[0054] It should be noted that the spliced ​​volute 20 located outside the shell 10 can serve as an expansion part of the air duct 11 to increase the air volume. The joints between the spliced ​​volute 20 and the volute side panels 12 are made of rubber materials or polymer materials with good air tightness to prevent air leakage from the volute enclosure or rigid contact that damages the shell components.

[0055] In one embodiment of the present application, the housing 10 has a ventilation port 111 connected to the air duct 11, and the ventilation port 111 and the first opening 101 are respectively arranged on the opposite side panels of the housing 10, and the electrical component 50 is arranged on the side of the spliced ​​volute 20 away from the ventilation port 111. This arrangement allows the ventilation port 111 and the first opening 101 to be located on different side panels, thereby preventing air leakage from interfering with the air permeability of the ventilation port 111 when the spliced ​​volute 20 is in the avoidance position, causing inconvenience in installation. At the same time, the first opening 101 and the ventilation port 111 are located on different side panels, and the sizes of the first opening 101 and the ventilation port 111 can be designed more flexibly, and the spliced ​​volute 20 has a larger space for the movement mode and range of movement at the first opening 101.

[0056] Furthermore, the electrical component 50 is detachably connected to the spliced ​​volute 20. This arrangement is simple in structure, and the electrical component 50 and the spliced ​​volute 20 can be divided into two parts and installed separately, thereby improving efficiency and saving costs.

[0057] Specifically, Figure 3 As shown, the electrical component 50 only includes an electric control board component 30, and the electric control board component 30 includes a connecting bracket 31 and an electric control board 32. The connecting bracket 31 has a first connecting end and a second connecting end that are arranged opposite to each other, and the first connecting end is detachably connected to the spliced ​​volute 20; the electric control board 32 is arranged at the second connecting end; when the electric control board component 30 is in the installation position, the electric control board 32 is located outside the housing 10. The connecting bracket 31 can provide a suitable installation structure for the electric control board 32. For example, the second connecting end of the connecting bracket 31 can be a plane, or the second connecting end can be a clamping structure, a limiting structure, etc. The first connecting end of the connecting bracket 31 can be set to a suitable connecting structure according to the structural characteristics of the spliced ​​volute 20. For example, when the connecting bracket 31 is connected to the arc-shaped spliced ​​volute 20, the first connecting end can also be set to an arc-shaped structure, so that the connection between the connecting bracket 31 and the spliced ​​volute 20 is more stable. The provision of the connecting bracket 31 can make the connection and disassembly of the electric control board 32 and the spliced ​​volute 20 more convenient, thereby improving the installation convenience of the housing assembly.

[0058] Preferably, the electric control panel assembly 30 is connected to the spliced ​​volute 20 by a threaded or lock connection, which is convenient for disassembly and has high stability during connection.

[0059] Specifically, Figure 3As shown, the connecting bracket 31 has a groove structure, the open end of the groove structure forms a first connecting end, and the side of the groove structure away from the open end forms a second connecting end. Since the connecting bracket 31 forms a groove structure, when the first connecting end is connected to the spliced ​​volute 20, part of the spliced ​​volute 20 extends into the groove structure, so that when the electric control board assembly 30 is connected to the spliced ​​volute 20, the longitudinal space of the housing assembly can be further reduced, and the setting of the groove structure can increase the contact area between the connecting bracket 31 and the spliced ​​volute 20, so that the electric control board assembly 30 follows the spliced ​​volute 20 to move more smoothly.

[0060] Furthermore, if Figure 2 As shown, the motion mechanism includes a guide rail 4, the guide rail 4 is connected to the housing 10, the spliced ​​volute 20 is movably connected to the guide rail 4, and the spliced ​​volute 20 is reciprocatingly arranged along the length direction of the guide rail 4, so that the spliced ​​volute 20 can be moved to a blocking position and an avoidance position along the length direction of the guide rail 4. By setting the guide rail 4 to be movably connected to the spliced ​​volute 20, the flexibility and convenience of the spliced ​​volute 20 are improved, and the position switching of the spliced ​​volute 20 can be achieved by only pushing and pulling the spliced ​​volute 20 along the sliding direction of the guide rail 4. At the same time, the direction and length of the guide rail 4 can further limit the range of movement of the spliced ​​volute 20, so that the movement of the spliced ​​volute 20 is controllable and more stable during the sliding process. The direction and length of the guide rail 4 can also be set to ensure that the spliced ​​volute 20 slides to the end of the guide rail 4 and accurately overlaps and seals with the remaining volutes.

[0061] It should be noted that in order to ensure that the spliced ​​volute 20 can accurately overlap and seal the shell 10 when sliding on the guide rail 4, the range of movement of the spliced ​​volute 20 can be further limited by means of buckles or elastic parts on the guide rail 4 and the inner plate of the spliced ​​volute 20.

[0062] Optionally, the motion mechanism further includes a rotating shaft 21 and a connecting rod 22, wherein the rotating shaft 21 is rotatably disposed in the housing 10; there is at least one connecting rod 22, the first end of the connecting rod 22 is connected to the rotating shaft 21, and the second end of the connecting rod 22 is connected to the spliced ​​volute 20; the rotation of the rotating shaft 21 drives the connecting rod 22 to rotate, thereby driving the spliced ​​volute 20 to move to the blocking position and the avoidance position. This arrangement can achieve position switching through the rotation of the spliced ​​volute 20, and the drive of the rotating shaft 21 can be achieved by a drive motor disposed in the housing 10, thereby making the motion control of the spliced ​​volute 20 more convenient.

[0063] In one embodiment of the present application, Figures 5 to 7As shown, the shell assembly enables the spliced ​​volute 20 to be movably connected to the volute side plate 12 by setting at least one rotating shaft 21 to connect with the spliced ​​volute 20. The rotating shaft 21 is set in the air duct 11. The rotating shaft 21 is connected to different positions of the spliced ​​volute 20 through connecting rods 22 of different lengths. When the rotating shaft 21 rotates, the connecting rods 22 of different lengths are connected to different positions of the spliced ​​volute 20 to perform circular motions of different radii, which can drive the spliced ​​volute 20 to move and achieve switching between the blocking position and the avoidance position, thereby driving the electric control board assembly 30 to move to the initial position and the installation position.

[0064] Alternatively, if Figure 1 , Figure 2 As shown, the first opening 101 is arranged to overlap with the second opening 120. This can further increase the flow area of ​​the air duct and improve the air output of the housing assembly.

[0065] like Figure 1 , Figure 2 As shown, in an exemplary embodiment of the present application, the volute side plate 12 is connected to the housing 10, and the volute side plate 12 is partially located in the first opening 101, so that the first opening 101 and the second opening 120 are arranged to overlap. In other embodiments, the volute side plate 12 and the inner wall of the housing 10 are abutted or connected, so that the first opening 101 and the second opening 120 are communicated and at least partially overlapped. In this embodiment, the motion mechanism also includes a spliced ​​volute 20, which is movably connected to the housing 10, and the electrical component 50 is arranged on the spliced ​​volute 20, and the electrical component 50 can move to the initial position and the installation position with the spliced ​​volute 20; the spliced ​​volute 20 has a blocking position that blocks the second opening 120, and also blocks the first opening 101, and the spliced ​​volute 20 has a avoidance position away from the first opening 101 and the second opening 120, and when the spliced ​​volute 20 is in the blocking position, the electrical component 50 is in the installation position. By setting the electrical component 50 on the spliced ​​volute 20, the position switching of the electrical component 50 can be achieved while achieving the position switching of the spliced ​​volute 20, reducing the setting of parts in the shell assembly, reducing the weight of the shell assembly and the number of parts, thereby making the structure of the shell assembly simpler and the manufacturing cost lower.

[0066] According to another specific embodiment of the present application, a ceiling appliance is provided, including a housing assembly, which is the housing assembly in the above embodiment. The ceiling appliance includes but is not limited to air outlet devices such as kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, fresh air blowers, and ventilation fans.

[0067] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0068] In addition to the above, it should be noted that "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application.
