Description

TECHNICAL FIELD

[0001] The utility model relates to the field of household appliances, and particularly relates to a shell assembly and a ceiling appliance with the same. BACKGROUND

[0002] Ceiling appliances are electrical devices installed in a ceiling, usually for lighting, ventilation, and air conditioning functions. The installation method of ceiling appliances is usually to embed the electrical device into the ceiling, making the whole look more beautiful and neat.

[0003] Common ceiling appliances include ceiling lamps, fans, integrated ceiling air conditioners, and bath heaters. Ceiling appliances are usually composed of a box, a duct assembly (such as a volute) arranged inside the box, and a fan assembly (such as a fan), etc. The performance of the ceiling appliance is mainly affected by the size and volume of the fan assembly and the duct assembly in the box.

[0004] A bath heater is a common indoor heating device, and its main function is to increase the temperature of the bathroom by heating air. The bath heater is usually composed of a box, a fan, and a volute, etc. The performance of the bath heater is mainly affected by the size of the fan and the volute. In the traditional design of the bath heater, the size of the box is limited by the size of the ceiling panel and the width of the keel, which limits the performance improvement of the bath heater. The existing technology increases the fan and the volute of the bath heater as much as possible within the original size, but the performance improvement of the bath heater is limited. Without increasing the size of the box, the only way to meet the air intake is to increase the fan speed, but increasing the fan speed will produce a lot of noise during operation.

[0005] In view of the above technical problems, no effective solution has been proposed so far. UTILITY MODEL CONTENTS

[0006] The main purpose of the utility model is to provide a shell assembly and a ceiling appliance with the same, to solve the problem of balancing the air intake of the volute of the ceiling appliance and the running noise of the ceiling appliance in the prior art.

[0007] In order to achieve the above purpose, according to one aspect of the utility model, a shell assembly is provided, which comprises: a shell having a volute side plate for forming an air duct, the side plate of the shell having an opening communicating with the air duct; a flexible splicing body connected with at least one of the shell and the volute side plate, the flexible splicing body being arranged at the opening, and the flexible splicing body having an initial position protrudingly arranged on the outer surface of the side plate, and the flexible splicing body having an avoiding position deformed from the initial position to the inside of the shell; wherein when the flexible splicing body is in the initial position, the flexible splicing body blocks at least part of the opening, so that the flexible splicing body and the volute side plate form a volute surrounding plate.

[0008] Furthermore, as the flexible assembly moves from its initial position to its avoidance position, it deforms toward the inside of the shell, so that at least a portion of the flexible assembly is housed inside the shell.

[0009] Furthermore, during the process of the flexible assembly moving from the avoidance position to the initial position, the flexible assembly deforms towards the outside of the shell to the initial position.

[0010] Furthermore, when the flexible assembly is in an avoidance position, it is housed within the air duct.

[0011] Furthermore, a first cavity is formed between the outer wall of the volute side plate and the side wall of the shell. When the flexible splice is in the avoidance position, the flexible splice is housed in the first cavity.

[0012] Furthermore, when the flexible splice is in its initial position, the flexible splice and the volute side plate form a volute enclosure that is at least partially arc-shaped.

[0013] Furthermore, when the flexible splice is in its initial position, the edges of the flexible splice are smoothly transitioned to the edges of the opening.

[0014] Furthermore, the housing has an air outlet communicating with the air duct, and the air outlet and the opening are respectively disposed on two side plates of the housing that are arranged opposite to each other along the first direction, and / or, the housing has an air outlet communicating with the air duct, and the air outlet and the opening are respectively disposed on two side plates of the housing that are adjacent to each other and connected to each other.

[0015] Furthermore, the volute side plate has a volute tongue structure, and an opening is provided on the side plate farther from the volute tongue structure among the two side plates that are arranged opposite each other along the first direction of the shell.

[0016] Furthermore, the first direction is the width direction of the shell, and / or the first direction is the length direction of the shell.

[0017] Furthermore, the flexible splice is an integral volute structure made of flexible material, with the volute structure having a smooth transition of curved surfaces along its length.

[0018] Furthermore, the flexible assembly includes multiple flexible units stacked along a preset arc, with adjacent flexible units movably connected to each other so that the flexible assembly can be deformably configured. The multiple flexible units have a first position that moves toward the inside of the shell and a second position that moves toward the outside of the shell.

[0019] According to another aspect of the present invention, a ceiling electrical appliance is provided, which includes a housing assembly, the housing assembly being the aforementioned housing assembly.

[0020] By applying the technical solution of this utility model, the housing has an internal air duct. By aligning the flexible splicing body with the opening, when the flexible splicing body is in its initial position, it at least partially blocks the opening. This allows the flexible splicing body and the side wall of the housing to form part of the side wall of the air duct, increasing the size of the volute and thus increasing the air intake. This avoids the defect in the prior art where the fan is limited by the housing size and can only ensure the air intake by increasing the fan speed. The flexible splicing body has a deformation from the initial position to a clearance position inside the housing, making the installation process simple and quick. The technical solution of this application solves the problem in the prior art of balancing the air intake of the ceiling appliance volute and the operating noise of the ceiling appliance.

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 therefore their description will be omitted.

[0039] Combination Figures 1 to 4 As shown, according to a specific embodiment of this application, a housing assembly is provided.

[0040] Specifically, such as Figure 1As shown, the housing assembly includes: a housing 10, the housing 10 having a volute side plate 12 for forming an air duct 11, the side plate of the housing 10 having an opening 101 communicating with the air duct 11; a flexible splice 20, the flexible splice 20 being connected to at least one of the housing 10 and the volute side plate 12, the flexible splice 20 being disposed at the opening 101, and the flexible splice 20 having an initial position protruding from the outer surface of the side plate, and a clearance position deforming from the initial position to the interior of the housing 10; wherein, when the flexible splice 20 is in the initial position, the flexible splice 20 blocks at least part of the opening 101, so that the flexible splice 20 and the volute side plate 12 surround a volute enclosure.

[0041] By applying the technical solution of this utility model, the housing 10 has an air duct 11. By correspondingly aligning the flexible splicing body 20 with the opening 101, when the flexible splicing body 20 is in its initial position, it blocks at least part of the opening 101. This allows the flexible splicing body 20 and the sidewall of the housing 10 to form part of the sidewall of the air duct 11, creating a complete air duct 11. This increases the size of the volute and the air intake, thus avoiding the deficiency in the prior art where the fan is limited by the size of the housing 10 and can only guarantee the air intake by increasing the fan speed. The flexible splicing body 20 has a clearance position that deforms from the initial position to the inside of the housing 10, making the installation process simple and quick. The technical solution of this application solves the problem in the prior art of balancing the air intake of the ceiling appliance volute and the operating noise of the ceiling appliance.

[0042] The housing 10 includes a volute side plate 12. When the flexible splice 20 is in the initial position, the flexible splice 20 and the volute side plate 12 and / or part of the side wall of the housing 10 form part of the side wall of the air duct 11.

[0043] Specifically, during the process of the flexible splice 20 moving from the initial position to the avoidance position, the flexible splice 20 deforms toward the inside of the shell 10 so that at least part of the flexible splice 20 is housed inside the shell 10.

[0044] Optionally, when the flexible splice 20 is in the initial position, it protrudes from the outer surface of the side plate. At this time, the flexible splice 20 and the volute side plate 12 surround the volute enclosure to form a complete air duct 11. When the flexible splice 20 is in the avoidance position, the part that originally protrudes from the outer surface of the side plate deforms toward the inside of the housing 10 so that it is housed inside the housing 10. At this time, there is no protruding part of the volute outside the housing 10.

[0045] Specifically, during the movement of the flexible splicing body 20 from the avoidance position to the initial position, the flexible splicing body 20 deforms towards the outside of the shell 10 to reach the initial position. The flexible splicing body 20 is correspondingly positioned to the opening 101, and the flexible splicing body 20 deforms at the opening 101 when moving from the avoidance position to the initial position or from the initial position to the avoidance position. The distance and position of the deformation of the flexible splicing body 20 towards the outside of the shell 10 are symmetrical to the distance and position of the deformation of the flexible splicing body 20 towards the inside of the shell 10.

[0046] Specifically, when the flexible splice 20 is in the avoidance position, it is housed within the air duct 11. Because the housing 10 has a volute side plate 12, which forms the air duct 11, and the side plate of the housing 10 has an opening 101 communicating with the air duct 11, the flexible splice 20 is positioned at the opening 101. The flexible splice 20 and the air duct 11 are connected. When the flexible splice 20 is in the avoidance position, it deforms towards the inside of the housing 10, deforming from the opening 101, and is housed within the air duct 11 of the housing 10.

[0047] Specifically, a first cavity 13 is formed between the outer wall of the volute side plate 12 and the side wall of the housing 10. The first cavity 13 can increase the structural strength of the volute. When the flexible splice 20 is in the avoidance position, the flexible splice 20 is housed in the first cavity 13. In order to ensure that the flexible splice 20 can be housed in the first cavity 13 when in the avoidance position, and to ensure that the size of the first cavity 13 matches the flexible splice 20, the volute structure needs to be designed and the installation position of the volute side plate needs to be determined.

[0048] Specifically, when the flexible splicing body 20 is in its initial position, the edge of the flexible splicing body 20 smoothly transitions to the edge of the opening 101. This smooth transition ensures that the flexible splicing body 20 will not be damaged or worn during use. The flexible splicing body 20 needs to move continuously between its initial and avoidance positions, deforming either towards the inside or outside of the housing 10. This deformation will generate friction at the edge of the flexible splicing body 20 and the edge of the opening 101. The smooth transition ensures that there is no excessive friction or resistance at the connection between the flexible splicing body 20 and the opening 101. Simultaneously, the smooth transition design also reduces the gap between the flexible splicing body 20 and the opening 101, preventing dust or other debris from entering the volute and protecting the internal mechanical structure of the volute from damage.

[0049] Specifically, the housing 10 has an air outlet 111 communicating with the air duct 11. The air outlet 111 and the opening 101 are respectively disposed on two side plates of the housing 10 that are opposite to each other along a first direction. Alternatively, the housing 10 has an air outlet 111 communicating with the air duct 11, and the air outlet 111 and the opening 101 are respectively disposed on two adjacent side plates of the housing 10 that are connected to each other. The placement of the air outlet 111 and the opening 101 affects the airflow direction and effect of the air duct 11.

[0050] Optionally, in this embodiment, the air outlet 111 and the opening 101 are respectively disposed on two side plates of the housing 10 that are opposite to each other along the first direction. By separately disposing the air outlet 111 and the opening 101 on the two side plates, air flow and circulation can be achieved, thereby effectively expelling indoor heat and moisture, keeping the indoor air fresh, and effectively reducing the temperature of the equipment, improving the stability and service life of the equipment. At the same time, separately disposing the air outlet 111 and the opening 101 on the two side plates can also reduce airflow resistance, make the airflow direction of the air duct more uniform, improve ventilation efficiency, and ensure the normal operation and safety of the equipment.

[0051] Specifically, the volute side plate 12 has a volute tongue structure 121, and the side plate of the shell 10 that is farther from the volute tongue structure 121 among the two side plates that are arranged opposite each other along the first direction has an opening 101.

[0052] Optionally, a volute tongue structure 121 on the volute side plate 12 can increase the strength and stability of the volute, prevent vibration and deformation during operation, and improve its service life and efficiency. The volute tongue structure 121 can increase the rigidity of the volute, making it more robust and durable, and reducing deformation and damage caused by excessive force. Simultaneously, the volute tongue structure can also reduce friction between the volute and other components, improving the volute's operating efficiency. In the air duct, the volute tongue structure 121 can increase the resistance of the air duct, thereby improving the speed and direction of airflow, allowing air to flow more evenly within the air duct, avoiding local blockages or backflow, and ensuring smooth airflow.

[0053] Optionally, the two volute side plates 12 arranged opposite each other along the first direction of the housing 10 form an air duct 11. An opening 101 is provided on the side plate farther from the volute tongue structure 121. Since the opening 101 is connected to the flexible splice 20, the purpose of providing an opening on the side plate farther from the volute tongue structure 121 is not only to make it easier for air to enter and exit the volute tongue structure 121, effectively improving airflow and ventilation, effectively reducing the temperature of the volute tongue structure and extending its service life, but also to facilitate the deformation of the flexible splice 20.

[0054] Specifically, the first direction is the width direction of the housing 10, and / or the first direction is the length direction of the housing 10.

[0055] Specifically, the flexible splice 20 is made of at least one of rubber, polyurethane, and graphene. The flexible splice 20 is generally made of elastic materials, which possess good flexibility and bending properties, enabling them to adapt to surfaces of different shapes and sizes for bonding and connection. Simultaneously, they can withstand certain tensile and compressive forces, maintaining the stability and reliability of the connection. Furthermore, elastic materials also have good wear resistance and aging resistance, ensuring a long service life.

[0056] Alternatively, rubber is elastic and soft, and can deform and return to its original shape when subjected to force. Rubber also has good wear resistance and corrosion resistance, and has certain shock absorption and vibration damping properties.

[0057] Polyurethane has good wear resistance and abrasion resistance, making it a durable material; polyurethane has good elasticity and flexibility; polyurethane has good strength and stiffness, and can be used to manufacture high-strength structural components; polyurethane has excellent processing performance and is easy to process into products of various shapes and sizes.

[0058] Graphene is one of the strongest materials known, more than 200 times stronger than steel. Graphene also possesses extremely high elasticity, allowing it to return to its original shape after being twisted and deformed.

[0059] The flexible splice body 20 is made of at least one of rubber, polyurethane, and graphene, which ensures that after the flexible splice body 20 moves from the initial position to the avoidance position or deforms from the avoidance position back to the initial position, the flexible splice body 20 returns to its original shape, thereby improving the service life of the flexible splice body 20.

[0060] Specifically, the flexible splice 20 is an integrated volute structure made of flexible material. The volute structure has a smooth transition along its length, which reduces the resistance and friction of the volute structure, making it more streamlined. Due to the smooth transition, the irregularity and unevenness of the structure surface are reduced, which reduces the wear and fatigue of the structure and extends its service life. The smooth surface helps to reduce the resistance of the structure in the fluid and is more conducive to the flow of air in the air duct.

[0061] Optionally, the one-piece molded volute structure offers higher strength and stability, allowing it to better resist external pressure and impacts as air flows through the duct 11. The one-piece molded volute structure, without seams or gaps, provides better sealing, reduces air leakage, and improves ventilation efficiency. Furthermore, the one-piece molded volute structure is less prone to cracking and wear, maintaining good service condition for a longer period.

[0062] Specifically, the flexible splice body 20 includes multiple flexible units, which are stacked along a preset arc. Adjacent flexible units are movably connected to each other so that the flexible splice body 20 can be deformably set. The multiple flexible units have a first position that moves toward the inside of the housing 10 and a second position that moves toward the outside of the housing 10.

[0063] Optionally, multiple flexible units can be stacked along a preset arc to ensure that the position and angle of each flexible unit are accurate. Stacking the flexible units along the preset arc allows for a more compact arrangement, saving space and ensuring that the flexible splice 20 is in a clearance position so as not to occupy too much space inside the shell 10.

[0064] Optionally, the movable connection between multiple flexible units can make the flexible splice 20 more flexible when deforming, and can adapt to different shapes and motion requirements. The movable connection between multiple flexible units can reduce the friction and stress concentration between the flexible units when the flexible splice 20 deforms, and extend the service life. The movable connection makes the flexible units easy to disassemble and replace, which is convenient for maintenance and repair.

[0065] Optionally, the multiple flexible units have a first position that moves toward the inside of the housing 10, which is the position of the multiple flexible units when the flexible splice 20 deforms toward the inside of the housing 10 during the movement of the flexible splice 20 from the initial position to the avoidance position, and a second position that moves toward the outside of the housing 10, which is the position of the multiple flexible units when the flexible splice 20 deforms toward the outside of the housing 10 during the movement of the flexible splice 20 from the avoidance position back to the initial position.

[0066] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0067] The main problem with existing technologies is that the size of the bathroom heater's housing is limited by the dimensions of the ceiling panel and the width of the keel, which in turn affects the size of the fan and the volute. This limitation restricts the performance improvement potential of the bathroom heater and cannot meet users' higher performance demands. Furthermore, while existing solutions can increase the size of the fan and volute through design improvements, this method is difficult to implement and costly. The housing assembly of the above embodiment, through a flexible splicing body, removes the installation limitations imposed by the size of the ceiling panel and the width of the keel, mainly solving the following technical problems: 1) How to increase the size of the bathroom heater's housing without changing the size of the ceiling panel and the width of the keel, thereby increasing the size of the fan and the volute and improving the performance of the bathroom heater; 2) How to increase the size of the fan and the volute while avoiding increasing implementation difficulty and cost; 3) How to improve the performance of the bathroom heater while ensuring its overall appearance and ease of installation.

[0068] During use, the operator can deform the flexible splicing body 20 by touching it, thereby switching the flexible splicing body 20 between the initial position and the avoidance position.

[0069] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0070] 1. This solution adds a flexible splicing body, which is then combined with the volute side plate to form a volute enclosure, creating a complete air duct. Without changing the overall size of the housing, the size of the volute is increased, the air duct capacity is expanded, the air intake is increased, and the air delivery performance is improved. This avoids the problem of having to increase the fan speed to ensure the air intake, which would otherwise generate a lot of noise during operation.

[0071] 2. The flexible splicing body can be deformably set. Before installation, the flexible splicing body can be recessed into the main body housing (i.e., the flexible splicing body is in an avoidance position). After installation, it can be manually pushed out to the outside of the machine body. At this time, the flexible splicing body is in the initial position. The whole installation process is simple, quick and easy to operate.

[0072] The above embodiments can also be applied to the field of equipment technology. Specifically, according to another specific embodiment of this utility model, a ceiling-mounted electrical appliance is provided, which includes a housing assembly, the same housing assembly as described in the above embodiments. Ceiling-mounted electrical appliances include, but are not limited to, air outlet devices such as kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, and fresh air systems.

[0073] When the housing assembly in the above embodiments is applied to ceiling appliances, the flexible splice can protrude outward to increase the flow area of ​​the air duct, and the housing can have a larger air volume, thereby making the air outlet effect of the ceiling appliances better, more suitable for environments with high air volume requirements, and improving the air outlet performance and practicality of the ceiling appliances.

[0074] In one embodiment of this application, the ceiling-mounted electrical appliance is a bathroom heater / ventilation unit. The bathroom heater / ventilation unit has the housing assembly described in the aforementioned embodiment, wherein the housing is the outer shell of the bathroom heater / ventilation unit, and the volute side plate of the air duct is formed in the housing. The air duct and the housing are two independently configured components. Alternatively, the volute side plate can be configured as a plate-like structure, and the air duct can be formed between the volute side plate, the side wall of the housing, and the bottom plate of the housing.

[0075] That is to say, in one embodiment of this application, the air duct 11 further includes an air duct top plate and an air duct bottom plate. The volute side plate 12, the air duct top plate, and the air duct bottom plate surround the shell 10, meaning that the air duct 11 is part of the structure of the shell 10, and the air duct bottom plate is formed from the bottom of the shell 10. The profile of the volute side plate 12 can be a volute profile, or it can be a profile structure including straight lines and curved lines.

[0076] In another embodiment of this application, the air duct 11 includes a volute side plate 12, an air duct top plate, and an air duct bottom plate. The air duct 11 and the housing 10 form a separate assembly component. Of course, the air duct 11 can also be independently formed inside the housing 10. In this case, the air duct bottom plate of the air duct 11 is connected to the bottom of the housing 10. The difference between this embodiment and the above embodiment is that both the air duct 11 and the housing 10 have their own bottom plates.

[0077] Specifically, a wind collector hood is provided on the side of the housing opposite to the bottom, and a panel is provided on the outside of the wind collector hood. The lamp body assembly is located on the side where the wind collector hood and the panel are located.

[0078] As will be understood by those skilled in the art, the housing assembly is installed in the ceiling space of an interior, which is typically formed by an integrated ceiling or large panel enclosure.

[0079] In one exemplary embodiment of this application, the air duct 11 is a volute air duct, and the housing also has an outlet air duct connected to the volute air duct along the length of the housing. The volute air duct has a snail shell structure, and the outlet air duct serves as the outlet of the snail shell structure. An outlet side plate is also provided inside the housing, connected to the volute side plate along the length of the housing. The outlet side plate and the air collecting plate together form the outlet air duct, and the air outlet is located in the outlet air duct, meaning the air outlet is the outlet of both the outlet air duct and the volute air duct.

[0080] Furthermore, the air collecting plate, as part of the air duct, is used to block one side of the air duct. Specifically, the volute side plate, the air collecting plate, and the bottom plate of the casing together form the volute air duct, wherein the air inlet of the volute air duct is located on the air collecting plate.

[0081] As an alternative implementation, the air collecting plate is integrally formed on the volute side plate, meaning the volute side plate and the bottom plate of the casing together form the volute air duct, with the air inlet of the volute air duct located on the top plate of the volute side plate. Alternatively, the bottom plate is integrally formed on the volute side plate, meaning the volute side plate and the air collecting plate together form the volute air duct, with the air inlet of the volute air duct located on the air collecting plate. Another alternative implementation involves the volute side plate being connected to a bottom plate and a top plate, meaning the volute side plate forms the volute air duct, with the air inlet of the volute air duct located on the top plate.

[0082] When the housing assembly is applied to a bathroom heater, the flexible splicing body protrudes outward onto the housing, increasing the airflow area of ​​the bathroom heater's duct. This allows for a larger airflow volume without modifying the dimensions of the bathroom heater fan and housing assembly, resulting in better airflow performance. Furthermore, the protruding portion of the flexible splicing body can be easily switched, reducing installation complexity and meeting different user airflow requirements. This achieves performance optimization and simplified installation in the bathroom heater technology field, enhancing the airflow performance and practicality of the bathroom heater.

[0083] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0084] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.

[0085] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0086] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
