Description

Technical Field

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

[0002] Common ceiling electrical appliances include air conditioners, bathroom heaters, and fresh air systems. Ceiling electrical appliances are usually composed of a housing, air duct components (such as a volute) and fan components (such as a fan) inside the housing. The performance of ceiling electrical appliances is mainly affected by the size and volume of the fan components and air duct components inside the housing.

[0003] For example, a bathroom heater is a common bathroom appliance, usually installed on the ceiling of the bathroom for heating and ventilation. The main components of a bathroom heater include the housing, fan, and volute. The size of the housing is limited by the joists, typically 270mm x 540mm. Within this limited space, the size of the fan and volute is also severely restricted. To address this issue, existing technology uses two fans to increase airflow. This solution supplies air to a single vent through two fans, thus increasing air volume. However, this solution requires installing both fans inside the housing, necessitating more space, which is a challenge given the limited size of the housing. Therefore, while existing technology can increase airflow by adding more fans, this requires more space, which is impractical for housings with limited dimensions. Due to the problems with existing technology, the airflow of bathroom heaters remains relatively low, failing to meet the needs of environments requiring higher airflow.

[0004] There is currently no effective solution to the aforementioned technical problems. Utility Model Content

The first air supply direction and the second air supply direction are arranged on the same side toward the geometric center of the width direction of the shell. In at least one air supply air duct, at least a portion of the air supply air duct protrudes from the outer surface of the shell along the width direction of the shell.

[0019] Furthermore, the first air duct's volute air duct has a first air outlet direction, and the second air duct's volute air duct has a second air outlet direction. The first air outlet direction and the second air outlet direction are located on both sides of the geometric center line of the shell's length direction, respectively.

It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0043] Combination Figures 1 to 7 As shown, according to a specific embodiment of this application, a housing assembly is provided.

[0044] Specifically, such as Figure 1 As shown, the housing assembly includes a housing 10, which has a plurality of air ducts 11. Each air duct 11 includes a volute air duct 101. The geometric centers of the plurality of volute air ducts 101 are spaced apart along the length of the housing 10. At least one of the plurality of air ducts 11 further includes a supply air duct 102 communicating with the volute air duct 101. At least a portion of the supply air duct 102 protrudes from the outer surface of the housing 10 along the width of the housing 10.

[0045] By applying the technical solution of this embodiment, multiple air ducts 11 are provided inside the housing 10. Each air duct 11 may be provided with an air supply duct 102 and a volute air duct 101. A portion of the air supply duct 102 protrudes along the width direction of the housing 10 on the outer surface of the housing 10. The protruding portion of the air supply duct 102 can be used to increase the capacity of the air duct 11, thereby increasing the air volume and improving the air outlet volume of the air duct 11 with the air supply duct 102, thereby improving the air outlet volume of the housing assembly. The outward protrusion of the air duct 11 can provide more space for the arrangement of fans inside the housing 10, so that more fans can be installed inside the housing 10, further improving the air outlet performance of the housing assembly. At the same time, the provision of multiple air ducts 11 inside the housing 10 can facilitate the distribution of air outlet of the housing assembly and improve the uniformity of air volume distribution.

[0046] It should be noted that the geometric center of the multiple volute air ducts 101 is the rotation center of the fan blade, that is, the volute air duct 101 is the air duct formed on the outer circumference of the fan blade.

[0047] In one embodiment of this application, such as Figure 1 , Figure 4 As shown, the housing 10 of the housing assembly has two air ducts 11, which are arranged along the length of the housing 10. One air duct 11 is provided with an air supply duct 102, while the other air duct 11 is not provided with an air supply duct 102. Part of the air supply duct 102 is provided protrudingly on the outer surface of the housing 10 along the width direction.

[0048] In another embodiment of this application, the housing 10 of the housing assembly has two air ducts 11, which are arranged along the length direction of the housing 10. Both air ducts 11 are provided with air supply ducts 102, and portions of the two air supply ducts 102 are protruding on the outer surface of the housing 10 along the width direction of the housing 10.

[0049] Specifically, such as Figure 2 As shown, the air supply duct 102 includes a duct body 111 and a splicing duct 112. The duct body 111 is connected to the volute duct 101. The duct body 111 has an opening 110. The splicing duct 112 has a clearance position away from the opening 110 and a blocking position that blocks at least part of the opening 110. When the splicing duct 112 is in the blocking position, at least part of the splicing duct 112 protrudes from the housing 10. When the splicing duct 112 is in the clearance position, the longitudinal space of the housing assembly is not affected. When the splicing duct 112 is in the blocking position, the splicing duct 112 blocks the opening 110 and connects to the housing 10, which can avoid the performance degradation caused by air leakage from the housing. When applied to electrical structures, it can effectively increase the air volume of the electrical appliance, adapt to the usage environment with large air volume requirements, improve the practicality of the electrical appliance, and solve the problems of insufficient air volume and low practicality of electrical appliances in the prior art.

[0050] Those skilled in the art will understand that when the spliced ​​air duct 112 is in the blocked position, the blocked position can block at least part of the opening 110. Since the spliced ​​air duct 112 is in this position, the capacity of the air duct 11 is expanded. When the housing assembly is running, the air volume can be increased, thereby improving the performance of the housing assembly. In this embodiment, the spliced ​​air duct 112 can increase the flow area of ​​the air duct.

[0051] In one embodiment of this application, such as Figure 3 As shown, multiple air ducts 11 are set independently of each other, and each air duct 11 does not affect the others. Each air duct 11 is also set with an air outlet at the air outlet end. The housing assembly can be divided into two air ducts with different air outlet effects. In combination with the above embodiment, air supply ducts 102 can be set in different air ducts 11, so that the air ducts 11 can be set with different air duct capacities.

[0052] In another embodiment of this application, at least two air ducts 11 are connected at their outlet ends, that is, at least two air ducts 11 are connected at their outlet ends, and multiple air ducts 11 can share the same air outlet, thereby increasing the air volume of the air outlet and improving the user experience.

[0053] Furthermore, such as Figure 3 As shown, the housing assembly also includes a cover plate 30, which has an assembly position for connecting to the housing 10 and a disassembly position for separating from the housing 10. The cover plate 30 has at least one air outlet 300, which is connected to at least one air duct 11. When the cover plate 30 is in the disassembly position, components inside the housing assembly, such as a fan, are installed. After the components are installed, the cover plate 30 is switched to the assembly position to achieve a seal after assembly, preventing components from falling off and preventing other debris from entering the housing assembly and affecting the performance of the internal components. The air outlet 300, located on the cover plate 30, allows air to exit from the bottom of the housing assembly, improving its performance.

[0054] Specifically, such as Figures 4 to 7 As shown, along the length of the housing 10, the ends of multiple air ducts 11 are positioned close to the same end of the housing 10, and along the width of the housing 10, the ends of the multiple air ducts 11 are positioned adjacent to each other, with the ends of the air ducts 11 connected to the air outlet 300. This arrangement connects the air outlet ends of multiple air ducts 11, meaning that the air outlet ends of multiple air ducts 11 are all connected to the air outlet 300 in position, facilitating the discharge of airflow through the air outlet 300 from one side and increasing the airflow volume through the air outlet 300.

[0055] In one embodiment of this application, multiple air ducts 11 are arranged independently of each other, and the ends of the multiple air ducts 11 may not be adjacent to each other. That is, the ends of the multiple air ducts 11 are arranged near different ends of the housing 10. For example, along the width direction of the housing 10, the ends of the multiple air ducts 11 are arranged at both ends of the housing 10, or along the length direction of the housing 10, the multiple air ducts 11 adopt different spiral directions, so that the ends of the air ducts 11 are arranged at both ends of the housing 10.

[0056] Optionally, an air outlet 300 is provided on the cover plate 30, and the air outlet 300 is configured to communicate with multiple air ducts 11. The multiple air ducts 11 dissipate air from the same air outlet 300, which can increase the air volume of the air outlet 300 and improve the performance of the housing assembly.

[0057] Optionally, such as Figure 3 As shown, the cover plate 30 has multiple air outlets 300, and each air duct 11 is connected to at least one air outlet 300. In this way, the position of the air outlet 300 can be set according to the setting position of the fan unit 20 and the arrangement space of the air duct 11, so as to make fuller use of the internal space of the housing assembly and set the air outlet position more flexibly.

[0058] In one embodiment of this application, such as Figure 3 , Figure 5 , Figure 7 As shown, multiple air outlets 300 are spaced apart along the width direction of the housing 10. By positioning the ends of multiple air ducts 11 at intervals on one side of the housing 10, the space within the housing 10 can be better utilized. Figure 4 , Figure 6 As shown, along the length of the housing 10, the air duct 11 of the fan closer to the air outlet 300 on the same side has a larger flow area, and the air volume is not affected by the air duct 11. The air duct 11 of the fan farther from the air outlet 300 can be provided with an air supply duct 102, which can increase the flow area of ​​the air duct 11 and also ensure that the air volume is not affected by the air duct 11, so that the housing assembly can maintain high performance during operation.

[0059] Optionally, such as Figure 3 As shown, the multiple air outlets 300 are set in different sizes. This allows the air outlets 300 to be set according to the air duct capacity of the multiple air ducts 11, so as to make full use of the space on the housing assembly. Alternatively, the multiple air ducts 11 can be set into high-level air volume air ducts 11 and low-level air volume air ducts 11 according to their different capacities. The high-level air volume air duct 11 corresponds to the large-sized air outlet 300, and the low-level air volume air duct 11 corresponds to the small-sized air outlet 300.

[0060] Furthermore, the spliced ​​air duct 112 is detachably connected to at least one of the air duct body 111 and the housing 10, so that the spliced ​​air duct 112 has a clearance position and a blocking position. The splicing of the spliced ​​air duct 112 to the housing 10 and the air duct body 111 in a detachable manner achieves the blocking of the opening 110. During the installation of the housing assembly, the spliced ​​air duct 112 can be separated first, and then the spliced ​​air duct 112 and the housing 10 can be connected through the installation ports to achieve the blocking. The detachable connection method also facilitates the individual maintenance and replacement of the spliced ​​air duct 112 and the housing 10 in the later stage.

[0061] Furthermore, such as Figures 1 to 7 As shown, each volute duct 101 is provided with at least one fan unit 20. Each fan unit 20 includes a motor and a fan, with the motor located at the rotation center of the fan, which is also the geometric center of the volute duct 101.

[0062] Specifically, the fan unit 20 includes a motor and a fan, and the fan includes an impeller and blades.

[0063] Preferably, the plurality of air ducts 11 include a first air duct and a second air duct, wherein both the first air duct and the second air duct are provided with a volute air duct 101 and an air supply air duct 102. The air supply air duct 102 of the first air duct has a first air supply direction arranged along the length direction of the housing 10, and the air supply air duct 102 of the second air duct has a second air supply direction arranged along the length direction of the housing 10. The first air supply direction and the second air supply direction are arranged on the same side toward the geometric center of the width direction of the housing 10. At least a portion of the air supply air duct 102 protrudes from the outer surface of the housing 10 along the width direction of the housing 10. By arranging the first air supply direction and the second air supply direction on the same side of the housing 10, the air volume of the air outlet can be increased to meet the user's large air volume requirements. Furthermore, by having at least a portion of the air supply air duct 102 protrude from the outer surface of the housing 10 along the width direction of the housing 10, the air volume and air supply rate of the air duct 11 can be further improved by increasing the flow area of ​​the air duct 11.

[0064] Furthermore, the first air duct's volute air duct 101 has a first air outlet direction, and the second air duct's volute air duct 101 has a second air outlet direction. The first and second air outlet directions are located on opposite sides of the geometric center line along the length of the housing 10. This arrangement allows for a more compact arrangement of the two air ducts 11, saving internal space in the housing 10.

[0065] like Figure 6As shown, the first air outlet direction is set to the left, so that the air supply duct 102 of the first air duct is set to the left of the volute duct 101 of the first air duct, and the second air outlet direction is set to the right, so that the air supply duct 102 of the second air duct is set to the right of the volute duct 101 of the second air duct.

[0066] Optionally, in an alternative embodiment of this application, the volute duct 101 of the first air duct has a first air outlet direction, and the volute duct 101 of the second air duct has a second air outlet direction. The first air outlet direction and the second air outlet direction are located on the same side of the geometric center line of the length direction of the housing 10. For example, the first air outlet direction and the second air outlet direction can both be arranged facing the left or right side.

[0067] Furthermore, along the length direction of the housing 10, the distance between the geometric center of the volute duct 101 of the first air duct and the end of the air supply duct 102 of the first air duct is less than the distance between the geometric center of the volute duct 101 of the second air duct and the end of the air supply duct 102 of the second air duct, wherein the volute duct 101 of the first air duct and the air supply duct 102 of the second air duct share at least a portion of the sidewall.

[0068] like Figure 6 As shown, the arrangement of the shared sidewalls can fully utilize the internal space of the housing 10, making the internal structural arrangement of the housing 10 more compact; at the same time, in Figure 6 In the first air duct, if the sidewall of the volute duct 101 of the second air duct supply duct 102 near the first air duct is straight, some airflow will easily collide with the sidewall of the second air duct supply duct 102 away from the first air duct, and interact with the airflow moving along the sidewall of the second air duct supply duct 102 away from the first air duct, resulting in airflow interference and airflow loss, affecting the outlet air velocity and air pressure. In this embodiment, since the volute duct 101 is an arc-shaped structure, the second air duct supply duct 102, with the help of the shared part of the arc-shaped sidewall, allows part of the airflow delivered by the volute duct 101 of the second air duct to flow along the shared part of the arc-shaped sidewall. This makes it easier for the airflow to merge with the airflow flowing along the sidewall of the second air duct supply duct 102 away from the first air duct during the flow process, and maintain the corresponding air velocity and air pressure.

[0069] Preferably, the volute duct 101 of the first air duct has a mating plane disposed near the volute duct 101 of the second air duct, and the mating plane is a straight surface structure.

[0070] like Figure 6 As shown, the straight-face structure reduces the space occupied by the volute duct 101 of the first air duct, which is beneficial to the internal structure arrangement of the housing 10. The volute duct 101 of the second air duct maintains a complete arc structure, which can keep the air outlet performance of the second air duct good.

[0071] Optionally, the volute duct 101 of the first air duct and the volute duct 101 of the second air duct share at least a portion of their sidewalls. This arrangement can further improve the compactness of the arrangement of the air ducts 11 within the housing 10 and increase the space utilization of the housing 10.

[0072] Furthermore, at least a portion of the second air duct supply duct 102 is provided protrudingly on the outer surface of the housing 10 along the width direction of the housing 10. Specifically, the second air duct supply duct 102 may include an air duct body 111 and a splicing air duct 112. The air duct body 111 is connected to the volute air duct 101. The air duct body 111 has an opening 110. The splicing air duct 112 has a clearance position away from the opening 110. The splicing air duct 112 also has a blocking position that blocks at least a portion of the opening 110. When the splicing air duct 112 is in the blocking position, at least a portion of the splicing air duct 112 protrudes from the housing 10. When the splicing air duct 112 is in the avoidance position, the longitudinal space of the housing assembly is not affected. When the splicing air duct 112 is in the blocked position, the splicing air duct 112 blocks the opening 110 and connects with the housing 10, which can avoid the performance degradation caused by air leakage from the housing. When applied to electrical structures, it can effectively increase the air volume of the electrical appliance, adapt to the usage environment with large air volume requirements, improve the practicality of the electrical appliance, and solve the problems of insufficient air volume and low practicality of electrical appliances in the prior art. Preferably, the splicing air duct 112 has an arc-shaped structure.

[0073] This application also provides a preferred embodiment of the housing assembly.

[0074] Specifically, the housing assembly includes a housing 10, a cover plate 30, and two fan units 20 disposed within the housing 10. The housing 10 has two air ducts 11, and each air duct 11 is provided with a fan unit 20. The cover plate 30 has an air outlet 300, which is located on the side where the short side of the cover plate 30 is located. The fan unit 20 closer to the air outlet 300 is the near-end fan unit, and the fan unit 20 farther from the air outlet 300 is the far-end fan unit. The part of the air duct 11 where the far-end fan unit is located is disposed outside the housing 10.

[0075] It should be noted that the ends of the two air ducts 11 are connected to the air outlet 300. The ends of the two air ducts 11 can be set independently or connected to each other. Depending on the actual needs, the ends of the two air ducts 11 can be connected and a detachable partition can be set. When it is necessary to isolate the ends of the two air ducts 11 from each other, the partition can be set inside the housing 10 to achieve the isolation of the two air ducts 11.

[0076] In this embodiment, the housing assembly employs a design with two fan units 20 supplying one air outlet 300, located on the shorter side to increase airflow. This design effectively increases airflow without increasing the size of the enclosure (i.e., housing 10), meeting user needs. Part of the air duct 11 of the distal fan unit is externally mounted outside the housing to avoid requiring more space due to additional fans. This also optimizes the layout of the two fans and the air duct design, reducing design complexity and difficulty. The well-designed air duct 11 ensures uniform air distribution and improves performance. The housing assembly in this embodiment allows for more even air distribution indoors, enhancing user comfort.

[0077] Compared to housing assemblies in the prior art, the housing assembly in the embodiments of this application has the following advantages:

[0078] 1. Optimized space utilization: In this embodiment, the housing assembly effectively solves the problem of limited space by placing part of the air duct 11 of the remote fan unit outside the housing, so that a large air volume can be achieved even in a housing with limited size.

[0079] 2.

The air duct 11 and the housing 10 can be two independently configured components. Part of the sidewall of the air duct 11 can also be formed on the housing 10. For example, a side plate can be provided, and the side plate, the sidewall of the housing 10, and the bottom plate of the housing form the air duct 11. Specifically, in conjunction with the previous embodiments, the cover plate 30 can be either a collector plate or a panel of the bathroom heater / ventilation unit. When the cover plate 30 is a collector plate, a panel is also provided on the outer side of the collector plate, and the lamp assembly is located on the same side as the collector plate and the panel.

[0086] When the housing assembly is applied to a bathroom heater, the splicing air duct 112 protrudes outward onto the housing 10, increasing the airflow area of ​​the bathroom heater. This allows the housing to have a larger air volume without modifying the dimensions of the bathroom heater fan and housing assembly, resulting in better airflow performance. Furthermore, the protruding part of the splicing air duct 112 is detachable, allowing for installation or removal according to different needs. This avoids installation complexity while meeting different airflow requirements, achieving performance optimization and simplified installation in the bathroom heater technology field, and improving the airflow performance and practicality of the bathroom heater.
