Description

Technical Field

[0001] The present invention relates to the field of ceiling-mounted electrical appliances, and more specifically, to a housing assembly and a ceiling-mounted electrical appliance having the same. This application claims priority to a patent application filed with the State Intellectual Property Office of China on July 26, 2024, with application number 202421803756.5 and utility model title “Housing assembly and ceiling-mounted electrical appliance having the same.” 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, impeller, and volute. The size of the impeller and volute is closely linked to the heater's performance.

[0003] In the existing technology, in order to improve the performance of the bathroom heater, attempts have been made to improve the size of the impeller and volute of the bathroom heater, so that the impeller and volute of the bathroom heater are increased as much as possible based on the original size. However, the limitation of this method is that the size of the impeller and volute is limited by the size of the box, and the size of the bathroom heater box is limited by the size of the ceiling gusset plate and the width of the keel. Therefore, the size of the impeller and volute is limited by the size of the ceiling gusset plate and the width of the keel. This limitation makes the performance improvement of the bathroom heater unable to meet the high demand of users for the performance of the bathroom heater. In addition, although the existing solution can increase the size of the impeller and volute by improving the design, this method is difficult to implement and the cost is also high.

[0004] To address the above issues, no effective solutions have been proposed so far. Utility Model Content

It should be understood that these embodiments are provided to make the disclosure of this 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 layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0048] Combine Figures 1 to 6 As shown, according to a specific embodiment of the present utility model, a housing assembly is provided.

[0049] Specifically, the housing assembly includes a housing 10 and a spliced ​​volute 20, the housing 10 has a volute side plate 12 for forming an air duct 11, and the side plate of the spliced ​​volute 20 has an opening 101; the spliced ​​volute 20 is detachably connected to at least one of the housing 10 and the volute side plate 12, the spliced ​​volute 20 has a blocking position connected to the housing 10 and at least partially blocking the opening 101, and the spliced ​​volute 20 has a position separated from the housing 10 and installed in the installation. The assembly position on the installation foundation; wherein, the spliced ​​volute 20 is connected to the shell 10, and the spliced ​​volute 20 and the volute side plate 12 are surrounded by a volute enclosure. The spliced ​​volute 20 can completely seal the opening 101, or it can partially block the opening 101, as long as most of the airflow can be guaranteed to flow out along the air duct. When the spliced ​​volute 20 is in the position to be assembled, the operating shell 10 is moved toward the side where the spliced ​​volute 20 is located, so that the shell 10 and the spliced ​​volute 20 are in a blocked position.

[0050] Optionally, in one embodiment of the present application, during installation, the spliced ​​volute 20 is first moved to the assembly position within the housing 10, and the housing 10 is operated to connect with the ceiling board or keel. After the connection is completed, the spliced ​​volute 20 is moved to the blocking position, or the housing 10 is located in the ceiling space, the spliced ​​volute 20 is moved to the blocking position, and then the housing 10 is connected with the ceiling board or keel, so that the ceiling appliance can be installed. This arrangement reduces the complexity of installation, breaks through the problem of low air output due to limited installation space in the prior art ceiling appliances, effectively increases the air output of the air duct, and effectively improves the air output or ventilation performance of the ceiling appliance.

[0051] Combine Figure 2 and Figure 4As shown, in one embodiment of the present application, the splicing volute 20 is detachably connected to the side wall of the shell 10 to enable the operating shell 10 to move toward the side where the splicing volute 20 is located (moving along the height direction of the ceiling space), so that the shell 10 and the splicing volute 20 are in a blocking position. When installing the shell assembly, the splicing volute 20 is installed in the to-be-assembled position on the installation base, and then the splicing volute 20 is connected to the shell 10, and the opening 101 is at least partially blocked in the blocking position, so that the shell assembly breaks through the problem of low air output caused by the limitation of the installation space. When the splicing volute 20 is in the blocking position, the splicing volute 20 is connected to the shell 10 and the opening 101 is sealed. This arrangement increases the air output of the shell assembly, improves the sealing performance of the shell assembly, and reduces the installation difficulty of the shell assembly, solves the problem of low air output due to limited installation space in the prior art shell assembly, and effectively improves the practicality of the shell assembly.

[0052] Furthermore, when the spliced ​​volute 20 is in the blocking position, at least part of the spliced ​​volute 20 is protruding outside the housing 10. This arrangement increases the air output of the housing assembly, solving the problem of low air output due to limited installation space in the prior art housing assembly.

[0053] In order to achieve the assembly effect of the shell assembly, the shell assembly also includes a guide assembly 30. The spliced ​​volute 20 is switched between the blocking position and the position to be assembled through the guide assembly 30. This arrangement improves the convenience of installing the shell assembly.

[0054] Optionally, the spliced ​​volute 20 slides along the height direction of the housing 10 to the blocking position and the position to be assembled through the guide assembly 30. This arrangement makes the operation of the housing assembly more convenient during installation.

[0055] In an exemplary embodiment of the present application, the spliced ​​volute 20 slides along the height direction of the shell 10 to the blocking position and the assembly position through the guide assembly 30, and the guide assembly 30 includes a first guide member 31 and a second guide member 32 that cooperate with each other. One of the first guide member 31 and the second guide member 32 is arranged on the shell 10, and the other of the first guide member and the second guide is connected to the spliced ​​volute 20.

[0056] Among them, the first guide member 31 and the second guide member 32 can be, but are not limited to, set as sliders and slide grooves, guide rails and pulleys, etc., as long as they can achieve cooperative sliding. When installing the shell assembly, first install the spliced ​​volute 20 in the position to be assembled on the installation base, and then slide the spliced ​​volute 20 along the height direction of the shell 10 through the first guide member 31 and the second guide member 32 until the spliced ​​volute 20 is located in the blocking position connected to the shell 10 and the opening 101 is at least partially blocked. Through this design, the shell assembly can not only realize the detachable setting of the spliced ​​volute 20, but also can switch between the blocking position and the position to be assembled as needed, which provides great convenience for the installation, disassembly and maintenance of the shell assembly. At the same time, this design can also ensure the sealing between the spliced ​​volute 20 and the shell 10, prevent gas leakage, and improve the performance and reliability of the shell assembly.

[0057] In a preferred embodiment of the present application, one of the first guide member 31 and the second guide member 32 includes a groove 311, and the other of the first guide member 31 and the second guide member 32 includes a sealing member 321 that cooperates with the groove 311. The sealing member 321 is preferably configured as a sealing plate, and may also be configured as a raised ridge, a slide rail, etc., as long as the sealing effect can be achieved. When the shell assembly is installed, the groove 311 guides the sealing member 321 that cooperates with it, so that the spliced ​​volute 20 moves to the sealing position. When the shell assembly needs to be assembled or maintained, the sealing member 321 moves in the opposite direction, thereby driving the spliced ​​volute 20 to move in the opposite direction, and moving the spliced ​​volute 20 to the position to be assembled. The groove 311 guides and limits the sealing member 321, thereby reducing the difficulty of installing the shell assembly.

[0058] Optionally, the spliced ​​volute 20 has a notch arranged toward the inner side of the shell 10. This arrangement increases the air output in the air duct 11 and improves the practicality of the shell assembly.

[0059] In order to achieve the assembly effect that the spliced ​​volute 20 can be switched between the blocking position and the ready-to-assemble position, the Figure 4 As shown, the spliced ​​volute 20 includes a spliced ​​volute body 21 extending along the length of the housing 10. Two spliced ​​volute side panels 22 are provided on either side of the spliced ​​volute body 21 in the lengthwise direction. The two spliced ​​volute side panels 22 and the spliced ​​volute body 21 form a volute structure with a notch on one side. A blocking member 321 extends circumferentially along the edge of the notch. This arrangement increases the airflow of the housing assembly while ensuring stable airflow.

[0060] Combine Figure 6As shown, in a preferred embodiment of the present application, the blocking member 321 is provided with a limiting protrusion 3212, so that the installation and positioning of the shell assembly can be achieved.

[0061] Combine Figure 6 As shown, in a preferred embodiment of the present application, a first flange structure 3211 is provided along one side of the length of the blocking member 321. A limiting protrusion 3212 and the first flange structure 3211 are provided on opposite sides of the length of the blocking member 321. When the spliced ​​volute 20 is in the blocking position, the first flange structure 3211 is located on the outside of the bottom of the housing 10. This arrangement strengthens the connection stability between the housing 10 and the blocking member 321. Once the connection is stable, the first flange structure 3211 serves to limit the height of the housing 10.

[0062] Combine Figure 2 、 Figure 4 and Figure 6 As shown, in a specific embodiment of the present application, the plane where the first flange structure 3211 is located is arranged at an angle to the plane where the blocking member 321 is located. When the spliced ​​volute 20 is in the blocking position, the first flange structure 3211 is located on the outside of the bottom of the housing 10, which helps to achieve quick and accurate positioning during installation, making the installation process more convenient.

[0063] Combine Figure 6 As shown, in a preferred embodiment of the present application, a groove 311 is provided at the edge of the opening 101, which is recessed toward the inside of the housing 10. When the spliced ​​volute 20 is in the blocked position, at least a portion of the blocking member 321 extends into the groove 311. This arrangement enhances the sealing performance of the spliced ​​volute 20 in the blocked position through the blocking member 321 and the groove 311, thereby improving the reliability of the housing assembly.

[0064] In order to further optimize the connection stability of the spliced ​​volute 20 when it is in the blocking position, at least one limiting section 102 is provided on the groove wall of the groove 311, and a limiting space 103 is formed between the limiting section 102 and the groove 311 (combined with Figure 4 and Figure 5 As shown), when the spliced ​​volute 20 is in the blocking position, part of the blocking member 321 extends into the limiting space 103 (combined with Figure 2 and Figure 3 This arrangement can better achieve the fixing and sealing effect of the blocking member 321. This design can effectively prevent various problems such as gas leakage caused by unstable connection between the groove 311 and the blocking member 321.

[0065] Combine Figure 2 and Figure 4As shown, in a preferred embodiment of the present application, at least two limiting sections 102 are provided on either side of the width direction of the mating groove 311, and the two limiting sections 102 are arranged opposite each other. One end of each limiting section 102 is connected to the housing 10, and the other end of each limiting section 102 extends away from the housing 10 along the length direction of the mating groove 311. This arrangement further improves the connection stability between the groove 311 and the blocking member 321, and optimizes the sealing effect of the housing assembly.

[0066] Combine Figure 4 As shown, in a preferred embodiment of the present application, the housing 10 has a second flange structure 104, which is arranged along the circumference of the housing 10. The second flange structure 104 is provided with at least one limiting groove 1041, which is provided in cooperation with the limiting protrusion 3212. Figure 4 and Figure 5 As shown, when the spliced ​​volute 20 is in the blocking position, the limiting protrusion 3212 on the blocking piece 321 is located in the limiting groove 1041 on the second flange structure 104, limiting the blocking piece 321, making the connection between the groove 311 and the blocking piece 321 more stable, thereby improving the reliability of the shell assembly.

[0067] In a preferred embodiment of the present application, the housing 10 is provided with a second flange structure 104, which is arranged along the circumference of the housing 10 to enhance the housing's stability and structural strength. The second flange structure 104 is provided with multiple retaining grooves 1041, and the blocking member 321 is provided with multiple retaining protrusions 3212. Each retaining groove 1041 cooperates with each retaining protrusion 3212 to achieve precise positioning and fixation. Specifically, the second flange structure 104 can be a portion of the housing 10, formed by adding additional material or structure to the edge of the housing. This design helps improve the overall rigidity and deformation resistance of the housing. The retaining grooves 1041 can be grooves on the second flange structure 104, with their shape and size matching the retaining protrusions 3212 to ensure a tight fit between them. The retaining grooves 1041 can be evenly distributed along the second flange structure 104, providing accurate positioning and fixing points for the retaining protrusions 3212. This design not only improves the stability of the overall structure but also facilitates quick and accurate positioning during installation.

[0068] In a preferred embodiment of the present application, when the spliced ​​volute 20 is in the blocking position, the first flange structure 3211 and the limiting protrusion 3212 extend in opposite directions away from the blocking member 321. This arrangement further improves the limiting strength of the spliced ​​volute 20 and the shell 10 in the horizontal and numerical directions.

[0069] In another embodiment of the present invention, a ceiling-mounted appliance is provided, including a housing assembly, which is the housing assembly of the above embodiment.

The housing assembly includes a housing 10 and a spliced ​​volute 20. The housing 10 has a volute side panel 12 for forming an air duct 11. The side panel of the housing 10 has an opening 101. The spliced ​​volute 20 is detachably connected to the housing 10. The spliced ​​volute 20 has a blocking position connected to the housing 10 and at least partially blocking the opening 101. The spliced ​​volute 20 has an assembly position separated from the housing 10 and mounted on an installation base. The spliced ​​volute 20 and the volute side panel 12 are arranged to form a volute enclosure. When the spliced ​​volute 20 is in the assembly position, the operating housing 10 is moved toward the side where the spliced ​​volute 20 is located, so that the housing 10 and the spliced ​​volute 20 are in the blocking position. The housing 10 is the outer shell of the bathroom heater main unit. The volute side panel 12 of the air duct 11 is formed in the housing 10. The air duct 11 and the housing 10 are two independently arranged components. Of course, the volute side plate 12 can also be set as a plate-like structure, and the volute side plate 12 and the side wall and bottom plate of the housing 10 are surrounded by an air duct 11. Specifically, an air collecting cover is provided on the side opposite to the bottom of the housing 10. A panel is provided on the outside of the air collecting cover, and the lamp body assembly is provided on the side where the air collecting cover and the panel are located.

[0071] When installing the shell assembly, the spliced ​​volute 20 is installed in the position to be assembled on the installation base, and then the spliced ​​volute 20 is connected to the shell 10, and the opening 101 is at least partially blocked in the blocking position, so that the shell assembly breaks through the problem of low air output caused by the limitation of the installation space. When the spliced ​​volute 20 is in the blocking position, the spliced ​​volute 20 is connected to the shell 10, and the spliced ​​volute 20 and the volute side plate 12 are surrounded to form a volute enclosure. The spliced ​​volute 20 can completely seal the opening 101, or it can partially block the opening 101, as long as it can ensure that most of the air flow flows out along the air duct. This arrangement increases the air output of the bathroom heater, improves the sealing performance of the bathroom heater, and reduces the difficulty of installing the shell assembly, solving the problem of low air output of the bathroom heater due to limited installation space in the prior art, and effectively improving the practicality of the bathroom heater.

[0072] In another embodiment of the present invention, a mounting structure is provided, comprising a housing assembly, which is the housing assembly described in the above embodiment.
