Description

Technical Field

[0001] This utility model relates to the field of volute technology, and more specifically, to a housing assembly and a ceiling appliance having the same. Background Technology

[0002] A bathroom heater is a common indoor heating device, its main function being to raise the temperature of the bathroom by heating the air. A bathroom heater typically consists of a housing, a fan, and a volute. The size of the housing directly affects the size of the fan and volute, thus impacting the performance of the bathroom heater. In traditional bathroom heater designs, the size of the housing is limited by the size of the ceiling panels and the width of the joists, resulting in the largest possible housing size in current technology. Further increasing the housing size to increase airflow would inevitably lead to an excessively large housing that cannot be installed through the mounting openings in the ceiling panels (standard structural components) or through the joists formed on the ceiling panels or large panels. Due to these existing technological limitations, the airflow of bathroom heaters remains relatively low, failing to meet the requirements of environments demanding higher airflow, thus limiting the practicality of current bathroom heater technology.

[0003] There is currently no good solution due to the problems with existing technologies. Utility Model Content

[0004] The main purpose of this utility model is to provide a housing assembly and a ceiling appliance having the same, so as to solve the problem of small air volume inside the housing due to the limited size of the volute in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a housing assembly is provided. The housing assembly includes: a main housing having a receiving cavity, a first opening on a side wall of the main housing, the main housing including a volute located within the receiving cavity, the volute having a second opening corresponding to the first opening; and a flexible splicing body connected to the main housing, the flexible splicing body having an initial position protruding outside the first opening, and a retractable position deforming towards the interior of the main housing to the interior of the second opening.

[0006] Furthermore, the housing assembly further includes: a stop assembly, the stop assembly being disposed on the main housing and detachably connected to the main housing, the stop assembly having a stop position for stopping the flexible splice body inside the second opening, and a release position for releasing the flexible splice body, wherein when the stop assembly is in the release position, the flexible splice body protrudes from the outer surface of the main housing.

[0007] Furthermore, the stop assembly is detachably connected to the main housing.

[0008] Furthermore, when the stop assembly is in the released position, the flexible splice deforms toward the outside of the main housing to its initial position.

[0009] Furthermore, when the stop assembly is in the stop position, at least a portion of the projection of the stop assembly onto the plane where the first opening is located overlaps with the opening surface of the first opening.

[0010] Furthermore, the stop assembly includes a stop member detachably connected to the sidewall of the outer periphery of the opening, the stop member having a stop position and a release position.

[0011] Furthermore, the stop is a plate-like structure, and the stop extends along the length direction of the opening.

[0012] Furthermore, the stop assembly also includes a fastener, which is detachably connected to the sidewall of the outer periphery of the opening.

[0013] Furthermore, the volute has a volute side plate that forms an air duct. When the flexible splice is in the initial position, the flexible splice and the volute side plate form part of the sidewall of the air duct.

[0014] Furthermore, the flexible splice is made of one of the following materials: rubber, polyurethane, or graphene.

[0015] According to another aspect of the present invention, a ceiling electrical appliance is provided, which includes a housing assembly, the housing assembly being the housing assembly described in the above embodiment.

[0016] By applying the technical solution of this utility model, a volute is set inside the receiving cavity of the main unit housing, and a flexible splicing body is connected to the main unit housing. Due to the use of flexible material, the flexible splicing body can deform, thus switching between the initial position and the storage position. This provides greater flexibility, and its position can be adjusted according to different usage scenarios or needs. When the flexible splicing body is in the storage position, it can save external space of the main unit housing and improve the internal space utilization of the main unit housing. At the same time, the housing structure adopting this structure can effectively reduce the installation space required for the installation of the housing components, improving the installation flexibility of the ceiling appliances with this housing component. Moreover, since the flexible splicing body protrudes from the main unit housing and is located on one side of the volute, it can increase the airflow of the volute, that is, effectively increase the air volume of the housing component, further improving the practicality and comfort of the ceiling appliances with this housing component.

[0032] Combination Figures 1 to 5 As shown, according to a specific embodiment of the present invention, a housing assembly is provided.

[0033] Specifically, such as Figure 1 As shown, the housing assembly includes: a main housing 10, the main housing 10 having a receiving cavity 11, a first opening 13 on the side wall 12 of the main housing 10, the main housing 10 including a volute 20, the volute 20 being located inside the receiving cavity 11, the volute 20 having a second opening 23, the second opening 23 being correspondingly provided with the first opening 13; and a flexible splicing body 30, the flexible splicing body 30 being connected to the main housing 10, the flexible splicing body 30 having an initial position protruding outside the first opening 13, and the flexible splicing body 30 having a storage position that deforms toward the inside of the main housing 10 to the inside of the second opening 23.

[0034] In this embodiment, a volute 20 is provided within the receiving cavity 11 of the main housing 10, and a flexible splicing body 30 is connected to the main housing 10. The flexible splicing body 30, being made of a flexible material, is capable of deformation, allowing it to switch between its initial position and its storage position. This provides greater flexibility, allowing its position to be adjusted according to different usage scenarios or needs. When the flexible splicing body 30 is in its storage position, it saves external space in the main housing 10, improving the internal space utilization rate. Furthermore, this housing structure effectively reduces the installation space required for the housing components, increasing the installation flexibility of the ceiling appliances with these components. Moreover, since the flexible splicing body protrudes from the main housing and is located on one side of the volute, it increases the airflow through the volute, effectively increasing the air volume of the housing components and further enhancing the practicality and comfort of the ceiling appliances with these components.

[0035] In one embodiment of this application, the air duct 21 further includes an air duct top plate and an air duct bottom plate. The volute side plate 22, the air duct top plate, and the air duct bottom plate surround the main unit housing 10, that is, the air duct 21 is a part of the structure of the main unit housing 10, and the air duct bottom plate is formed from the bottom of the main unit housing 10. The profile of the volute side plate 22 can be a volute profile, or the profile of the volute side plate 22 can be a profile structure including straight lines and curved lines.

[0036] In another embodiment of this application, the air duct 21 includes a volute side plate 22, an air duct top plate, and an air duct bottom plate. The air duct 21 and the main unit housing 10 form a separate assembly component, that is, the air duct 21 is part of the main unit housing 10, and the bottom of the main unit housing 10 forms the air duct bottom plate. Of course, the air duct 21 can also be independently formed inside the main unit housing 10. In this case, the air duct bottom plate of the air duct 21 is connected to the bottom of the main unit housing 10. The difference between this embodiment and the above embodiment is that both the air duct 21 and the main unit housing 10 have their own bottom plates.

[0037] The housing assembly also includes a stop assembly 40, which is disposed on the main housing 10 and is detachably connected to the main housing 10. The stop assembly 40 has a stop position that stops the flexible splicing body 30 inside the second opening 23, and a release position that releases the flexible splicing body 30. When the stop assembly 40 is in the release position, the flexible splicing body 30 protrudes from the outer surface of the main housing 10.

[0038] By setting a detachable connection between the stop assembly 40 and the main housing 10, the stop assembly 40 has a stop position and a release position. When the stop assembly 40 is in the stop position, it is connected to the main housing 10, and the flexible splice 30 is located in the receiving cavity 11 under the stopping action of the stop assembly 40, which can save the external space of the main housing 10 and improve the internal space utilization of the main housing 10. When the stop assembly 40 is in the release position, it is detached from the main housing 10, and the flexible splice 30, based on its own flexible material, is released to the outer surface of the main housing 10 under the action of its elastic restoring force, which can increase the flow area of ​​the air duct 21, thereby increasing the air volume. This setting improves the flexibility of the housing assembly, and the position of the flexible splice 30 can be adjusted by operating the stop assembly 40 according to actual needs to meet the usage requirements.

[0039] Combination Figure 1 , Figure 5 As shown, Figure 1 This is a top view of the stop assembly of the housing assembly in the stop position. Figure 4 This is a schematic diagram of the housing assembly's stop component when it is in the stop position. By operating the stop component 40, the flexible splicing body 30 can switch between its initial position and its retracted position. Furthermore, due to its unique material, the flexible splicing body 30 allows for deformation, thus enabling it to switch between the initial and retracted positions. This provides greater flexibility, allowing its position to be adjusted according to different usage scenarios or needs. When the flexible splicing body 30 is in the retracted position, it saves external space in the main housing 10, improving the internal space utilization of the main housing 10.

[0040] Furthermore, when the stop assembly 40 is in the released position, the flexible splice 30 deforms toward the outside of the main housing 10 to the initial position.

[0041] Combination Figure 3 , Figure 4 As shown, Figure 3 A top view of the stop assembly of the housing assembly in the released position. Figure 4 This is a schematic diagram of the stop assembly of the housing assembly in the released position. With the stop assembly removed, the flexible splice 30 is freed from the restriction of the stop assembly 40 and, under the action of its elastic restoring force, is positioned towards the outside of the main housing 10, protruding beyond the outside of the main housing 10. At this point, the flexible splice 30 forms an additional air guiding structure, increasing the flow area of ​​the air duct 21, thereby increasing the airflow.

[0042] When the stop assembly 40 is in the stop position, at least a portion of the projection of the stop assembly 40 onto the plane containing the first opening 13 overlaps with the opening surface of the first opening 13. The opening surface of the first opening 13 is the plane containing the opening.

[0043] Combination Figure 5 As shown, when the stop assembly 40 is in the stop position, the stop assembly 40 partially closes the first opening 13. The stop assembly 40 is connected to the side wall 12 on the outer periphery of the first opening 13 to prevent the flexible splice 30 from extending out of the first opening 13 under the action of elastic restoring force.

[0044] Furthermore, the stop assembly 40 includes a stop member 41, which is detachably connected to the side wall 12 of the outer periphery of the first opening 13, and the stop member 41 has a stop position and a release position.

[0045] Combination Figure 5 As shown, the detachable connection between the stop 41 and the side wall 12 surrounding the opening 13 allows the stop 41 to be installed or removed as needed. This design facilitates maintenance and replacement of the stop, improving product usability and flexibility.

[0046] In some optional embodiments, the stop 41 may be equipped with an automatic adjustment mechanism, enabling the stop 41 to automatically find a suitable stopping position based on the actual length of the opening 13. This can be achieved through sensors and microcontrollers, improving the intelligence level of the system.

[0047] Furthermore, the stop 41 is a plate-shaped structure, and the stop 41 extends along the length direction of the opening 13.

[0048] Specifically, the two ends of the plate-shaped stop 41 are detachably connected to the side walls 12 on both sides of the opening 13, which makes the structure simple and cost-effective.

[0049] like Figure 2 As shown, the stop assembly 40 also includes a fastener 42, through which the stop 41 is detachably connected to the sidewall 12 of the outer periphery of the opening 13. This arrangement improves the replaceability and flexibility of the stop 41.

[0050] In this embodiment, the fixing member 42 is a screw, and the stop member 41 is connected to the side wall 12 by a screw connection. In other embodiments, the stop member 41 and the side wall 12 can also be connected by magnetic connection, plug-in connection, etc.

[0051] Furthermore, the volute 20 has a volute side plate 22 forming the air duct 21. When the flexible splice 30 is in its initial position, the flexible splice 30 and the volute side plate 22 form part of the sidewall of the air duct 21, wherein the sidewall of the air duct formed by the flexible splice 30 is arc-shaped. This arrangement increases the flow area of ​​the air duct 21, thereby increasing the air volume. Furthermore, it allows for the installation of a larger impeller within the air duct 21, i.e., within the volute air duct, thereby increasing the air output of the air duct 21.

[0052] The flexible splice 30 can be connected to the main housing 10 or to the volute side plate 22. In this embodiment, the volute air duct is located inside the fan. The air duct 21 includes the volute side plate 22 and the air supply duct 24. The volute side plate 22 and the air supply duct 24 are integrally formed. One end of the volute side plate 22 and one end of the air supply duct 24 form a second opening 23. The air supply duct 24 is connected to the air outlet 25 of the fan.

[0053] Furthermore, the flexible splice 30 is made of one of rubber, polyurethane, or graphene. Both rubber and polyurethane possess excellent elasticity and flexibility, enabling the flexible splice to adapt to different working environments and usage conditions. Graphene, as a material with superior mechanical properties, can significantly improve the durability and fatigue resistance of the flexible splice.

[0054] According to another aspect of the present invention, a ceiling-mounted electrical appliance is provided, comprising a housing assembly, which is the housing assembly described in the above embodiment. The housing assembly includes: a main housing 10, a volute 20, a flexible splicing body 30, and a stop assembly 40. The main housing 10 has a receiving cavity 11, the volute 20 is located within the receiving cavity 11, the volute 20 has a volute side plate 22 forming an air duct 21, the flexible splicing body 30 is connected to the volute side plate 22, and the stop assembly 40 is detachably connected to the main housing 10. The stop assembly 40 has a stop position that stops the flexible splicing body 30 within the receiving cavity 11, and a release position that releases the flexible splicing body 30. When the stop assembly 40 is in the release position, the flexible splicing body 30 protrudes from the outer surface of the main housing 10.

[0055] By providing a volute 20 within the receiving cavity 11 of the main housing 10, and connecting a flexible splice 30 to the volute side plate 22 of the volute 20, the flexible splice 30, made of a flexible material, is capable of deformation. A stop assembly 40 is detachably connected to the main housing 10, allowing the stop assembly 40 to have a stop position and a release position. When the stop assembly 40 is in the stop position, it is connected to the main housing 10, and the flexible splice 30 is positioned within the receiving cavity 11 under the stopping action of the stop assembly 40, thus saving space in the main housing 10. The external space of 0 improves the space utilization rate inside the main unit housing 10. When the stop component 40 is in the release position, the stop component 40 is separated from the main unit housing 10. The flexible splice 30, based on its own flexible material, is released to the outer surface of the main unit housing 10 under the action of its elastic restoring force, which can increase the flow area of ​​the air duct 21, thereby increasing the air volume. This setting improves the flexibility of the housing component. The stop component 40 can be operated to adjust the position of the flexible splice 30 according to actual needs to meet the usage requirements.

[0056] Ceiling-mounted electrical appliances include, but are not limited to, kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, and fresh air systems.
