Description

Technical Field

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

[0002] Common ceiling-mounted appliances include air conditioners, bathroom heaters, and fresh air blowers. Bathroom heaters, as a common indoor heating device, primarily heat the air to increase the bathroom temperature. These heaters typically consist of a housing, fan, and volute. The size of the fan and volute is closely linked to the heater's performance.

[0003] In existing technologies, attempts have been made to improve the performance of bathroom heaters by improving the size of their fans and volutes, thereby increasing their original sizes as much as possible. However, this approach is limited in that the size of the fan and volute is limited by the size of the heater housing, which in turn is limited by the size of the ceiling panels and the width of the keel. Consequently, the size of the fan and volute is limited by the size of the ceiling panels and the width of the keel. This limitation prevents the performance improvement of the bathroom heater from meeting the high demands of users for bathroom heater performance. Utility Model Content

[0036] Combine Figures 1 to 5 As shown, according to a specific embodiment of the present application, a housing assembly is provided.

[0037] Specifically, combined Figure 1 As shown, the shell assembly includes a shell 1 and a spliced ​​volute 3. The shell 1 has a volute side plate 2 for forming an air duct 12, and the shell 1 has an air outlet 11 connected to the air duct 12, and the volute side plate 2 is provided with an opening 13. The spliced ​​volute 3 is movably connected to the shell 1 so that the spliced ​​volute 3 has an assembly position that blocks the opening 13, and has an avoidance position away from the opening. When the spliced ​​volute 3 is in the assembly position, at least part of the spliced ​​volute 3 is located outside the shell 1, and the spliced ​​volute 3 and the volute side plate 2 are surrounded by a volute enclosure. Among them, the spliced ​​volute 3 is provided with a ventilation structure 31. When the spliced ​​volute 3 is in the assembly position, the ventilation structure 31 is selectively connected to the air duct.

[0038] In an embodiment of the present application, the volute side plate 2 located inside the shell 1 and the spliced ​​volute 3 located outside the shell 1 form a volute enclosure, that is, the width of the volute enclosure is greater than the width of the shell, and the air output of the shell assembly is increased by increasing the size of the volute enclosure. At the same time, the volute enclosure is designed to be a spliced ​​structure, and the position of the spliced ​​volute 3 is controlled according to the installation environment, so as to achieve the problem of not being restricted by the installation space even if the size of the shell assembly is increased; while the size of the volute enclosure is increased, the size of the fan installed in the volute enclosure can be increased accordingly without exceeding the shell, so as to further increase the air output of the shell assembly; the ventilation structure is provided on the spliced ​​volute, that is, the ventilation structure and the spliced ​​volute are an integrated structure. During installation, the ventilation structure and the spliced ​​volute are installed as a whole. Compared with the installation method in the prior art in which the ventilation structure is installed separately as a split component, the installation steps of the shell assembly are simplified. Assembly position The shell assembly in the above scheme sets the volute enclosure into a spliced ​​structure to increase the size of the volute enclosure and the fan size, thereby increasing the air output of the shell assembly to solve the problem of low air output due to limited installation space of the shell assembly.

[0039] As those skilled in the art will appreciate, the housing assembly is installed within the indoor overhead space, typically formed by an integrated ceiling or large panels. The ventilation structure is located on the exterior of the housing and is a protruding structure that projects outward from the housing. To accommodate various installation environments, such as integrated ceilings and large panels, the ventilation structure is typically designed as a detachable component. During installation, the ventilation structure is first installed in a pre-set position, followed by the housing, and the connection between the ventilation structure and the housing is completed.

[0040] In an exemplary embodiment of the present application, Figure 4 As shown, the volute enclosure is a component of the air duct 12 , and the volute enclosure, the air collecting plate 17 and the bottom plate of the shell 1 are together arranged to form the air duct 12 , wherein the air inlet of the air duct 12 is opened on the air collecting plate 17 .

[0041] As an alternative embodiment, the volute enclosure has a top plate, that is, the wind collecting plate 17 is integrally formed on the volute enclosure, that is, the volute enclosure and the bottom plate of the shell 1 are jointly arranged to form an air duct 12, wherein the air inlet of the air duct 12 is opened on the top plate of the volute enclosure.

[0042] As an alternative embodiment, the volute enclosure has a bottom plate, that is, the bottom plate is integrally formed on the volute enclosure, that is, the volute enclosure and the wind collecting plate 17 are jointly arranged to form the air duct 12, wherein the air inlet of the air duct 12 is opened on the wind collecting plate 17.

[0043] As an alternative embodiment, the volute enclosure has a bottom plate and a top plate, that is, the volute enclosure is arranged to form the air duct 12, wherein the air inlet of the air duct 12 is opened on the top plate.

[0044] It should be noted that when the spliced ​​volute 3 is in the assembly position, the spliced ​​volute 3 blocks the opening 13, that is, the spliced ​​volute 3 and the volute side plate 2 are sealed, or the spliced ​​volute 3 and the volute side plate 2 are non-sealed.

[0045] In another exemplary embodiment of the present application, when the spliced ​​volute 3 is in the avoidance position, the spliced ​​volute 3 is separated from the housing 1. That is, when the spliced ​​volute 3 is in the avoidance position, the spliced ​​volute 3 is located outside the housing 1, and the spliced ​​volute 3 is completely separated from the housing 1.

[0046] Furthermore, the housing 1 is provided with a limiting assembly. When the spliced ​​volute 3 is in the assembled position, the limiting assembly cooperates with the spliced ​​volute 3 to limit the spliced ​​volute 3 from separating from the housing 1 along the width direction and / or length direction of the housing 1. The provision of the limiting assembly allows the housing 1 and the spliced ​​volute 3 to be initially positioned to facilitate assembly and disassembly between the two.

[0047] Preferably, the spliced ​​volute 3 is slidably engaged with the limiting assembly so that the spliced ​​volute 3 can be moved to the assembly position and the avoidance position along the height direction of the housing 1. That is, the limiting assembly limits the spliced ​​volute 3 from moving relative to the housing 1 along the width direction and the length direction of the housing 1.

[0048] Furthermore, the spliced ​​volute 3 includes a docking plate 32. When the spliced ​​volute 3 is in the assembly position, the docking plate 32 is arranged to fit the side wall of the shell 1, and the spliced ​​volute 3 is slidably matched with the limit assembly through the docking plate 32.

[0049] Specifically, if Figure 3 As shown, the docking plate 32 is arranged around the docking port of the spliced ​​volute 3. During the installation process, the docking plate 32 slides with the limiting assembly to enable the docking plate 32 to slide smoothly along the height direction of the shell 1 to the assembly position.

[0050] In an exemplary embodiment of the present application, the limiting assembly includes a groove 14, which is arranged around the opening 13. When the spliced ​​volute 3 is in the assembly position, the docking plate 32 extends into the groove 14 along the height direction of the shell 1, and the groove 14 limits the movement of the docking plate 32 along the length direction of the shell 1.

[0051] Specifically, if Figure 2 As shown, the groove 14 is arranged around the opening 13 and is recessed inwardly along the width direction of the housing 1. The length of the groove 14 is equal to or slightly greater than the length of the docking plate 32, so that the docking plate 32 extends into the groove 14 and restricts the docking plate 32 from moving along the length direction of the housing to escape from the groove 14.

[0052] Furthermore, the limiting assembly also includes a limiting plate 15, which is arranged opposite to the groove 14, and a limiting space 16 is formed between the limiting plate 15 and the groove 14. When the spliced ​​volute 3 is in the assembly position, the docking plate 32 extends into the limiting space 16 along the height direction of the shell 1, and the limiting plate 15 limits the movement of the docking plate 32 along the width direction of the shell 1.

[0053] Specifically, if Figure 2 、 Figure 4 As shown, there are two limit plates 15, which are arranged on the left and right sides of the groove 14 along the length direction of the shell 1. The limit plates 15 are arranged opposite to the short sides of the groove 14 along the width direction of the shell 1, so that a limit space is formed between the limit plates 15 and the groove 14, and the docking plate 32 is clamped in the limit space, that is, the docking plate 32 is clamped between the groove 14 and the limit plates 15, and the limit plates 15 limit the movement of the docking plate 32 along the width direction of the shell 1.

[0054] As an alternative embodiment, the limiting plate 15 may be disposed opposite to the long side of the groove 14 along the width direction of the housing 1 .

[0055] Furthermore, a flange 33 is provided on the edge of the docking plate 32, and the flange 33 extends along the length direction of the docking plate 32. The flange 33 is set at an angle to the docking plate 32. When the spliced ​​volute 3 is in the assembly position, the flange 33 is detachably connected to the shell 1.

[0056] Specifically, if Figure 3 、 Figure 5 As shown, flange 33 is perpendicular to docking plate 32 and is provided with mounting holes. Flange 33 is connected to the bottom of housing 1 via screws. Flange 33 also serves as a positioning mechanism. When flange 33 abuts the bottom of the housing, the assembled volute 3 is positioned, eliminating the need for alignment via mounting holes. Flange 33 is connected to housing 1 via screws, providing a simple and reliable connection.

[0057] In an exemplary embodiment of the present application, a damper 4 is provided in the ventilation structure 31 or the air duct 12 , and the damper 4 has a first working state for connecting the ventilation structure 31 and the air duct 12 , and a second working state for cutting off the connection between the ventilation structure 31 and the air duct 12 .

[0058] Specifically, if Figure 1 、 Figure 2 As shown, the ventilation structure 31 is a ventilation port integrally formed on the spliced ​​volute 3, which is set through the spliced ​​volute 3, and a damper is provided in the air duct 12. Exemplarily, the damper 4 is a push-pull plate or a rotating plate, which is driven to move to achieve communication and isolation between the ventilation port and the air duct 12.

[0059] Furthermore, when the damper 4 is in the first working state, the damper 4 extends into the spliced ​​volute 3 .

[0060] Specifically, if Figure 6 、 Figure 7 As shown, the damper 4 is disposed within the air duct 12 and is rotatably connected to the volute side panel 2. When the damper 4 is in a first operating state, a portion of the damper 4 extends into the spliced ​​volute 3, thereby reducing the damper 4's obstruction of the air duct 12 and increasing the effective space of the air duct 12, thereby increasing the air output. When the damper 4 is in a second operating state, the damper 4 is completely located within the volute side panel 2.

[0061] According to another specific embodiment of the present application, a ceiling-mounted appliance is provided, comprising a housing assembly, which is the housing assembly described in the above embodiment. The ceiling-mounted appliance includes, but is not limited to, air outlet devices such as kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, and fresh air blowers.

[0062] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0063] 1. The volute side panels 2 located inside the shell 1 and the spliced ​​volute 3 located outside the shell 1 form a volute enclosure, that is, the width of the volute enclosure is greater than the width of the shell. The air output of the ceiling appliance is increased by increasing the size of the volute enclosure. At the same time, the volute enclosure is designed as a spliced ​​structure, and the position of the spliced ​​volute 3 is controlled according to the installation environment, so that even if the size of the shell assembly is increased, it will not be limited by the installation space.

[0064] 2. As the size of the volute enclosure increases, the size of the fan installed in the volute enclosure can be increased accordingly without exceeding the casing, so as to further increase the air output of the volute.

[0065] 3. The ventilation structure is arranged on the spliced ​​volute, that is, the ventilation structure and the spliced ​​volute are an integrated structure. During installation, the ventilation structure and the spliced ​​volute are installed as a whole. Compared with the installation method in the prior art in which the ventilation structure is installed separately as a split part, the installation steps of the shell assembly are simplified.

[0066] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. 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 figures. For example, if the device in the 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.

[0067] In addition to the above, it should be noted that references to "one embodiment," "another embodiment," "an embodiment," and the like in this specification refer to specific features, structures, or characteristics described in conjunction with that embodiment as being included in at least one embodiment generally described in this application.
