[0002] Common ceiling-mounted appliances include air conditioners, bathroom heaters, fresh air blowers, and ventilation fans. 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

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.

[0057] Combine Figures 1 to 12 As shown, according to a specific embodiment of the present utility model, a ceiling-mounted electrical appliance is provided.

[0058] Specifically, the ceiling appliance includes a housing 10, a spliced ​​volute 20 and an impeller 40, wherein the impeller 40 is driven by a motor, the housing 10 has a duct side plate for forming an air duct 11, the air duct 11 includes a volute duct 113 and an air supply duct 114, the duct side plate includes a volute side plate 12 and an air supply side plate 1140, the volute side plate 12 has an opening 101; the impeller 40 is arranged in the volute duct 113, and the impeller 40 can selectively rotate in the reverse direction. The spliced ​​volute 20 is arranged to rotate in the clockwise and clockwise directions; the spliced ​​volute 20 is connected to the shell 10, and the spliced ​​volute 20 has a blocking position and a position to be assembled; wherein, when the spliced ​​volute 20 is in the blocking position, the spliced ​​volute 20 and the volute side plate 12 are arranged to form a volute enclosure, the volute enclosure forms the volute air duct 113, and the air supply side plate 1140 forms the air supply air duct 114, and at least part of the spliced ​​volute 20 is arranged protrudingly on the outside of the shell 10. Among them, the ceiling appliances include but are not limited to kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, fresh air blowers, ventilation fans and other devices. So that a larger impeller 40 can be set in the air duct 11, that is, in the volute air duct 113, thereby increasing the air output of the air duct 11. The spliced ​​volute 20 can be connected to the shell 10, or it can be connected to the volute side plate 12, as long as the spliced ​​volute 20 and the volute side plate 12 can be jointly arranged to form a volute enclosure. The impeller 40 is disposed within the volute enclosure, which forms at least a portion of the fan housing. The volute duct 113 is at least partially located within the fan. In this embodiment, the volute duct 113 is located within the fan. The air supply duct 114 is connected to the fan outlet.

[0059] In another exemplary embodiment of the present application, the housing 10 includes a box body, the air duct 11 is arranged in the box body, the air duct 11 includes a volute side panel 12, and the spliced ​​volute 20 can be connected to the box body, or to the volute side panel 12 forming the air duct 11, or to both the box body and the volute side panel 12, as long as the spliced ​​volute 20 can be switched between a blocked position and a position to be assembled. When installing the ceiling appliance, the spliced ​​volute 20 is installed or moved to the position to be assembled, and then the spliced ​​volute 20 is moved or the housing 10 is operated so that the spliced ​​volute 20 is switched to the blocked position connected to the housing 10, so that the ceiling appliance breaks through the problem of low air output caused by installation space limitations. When the spliced ​​volute 20 is in the blocking position, the spliced ​​volute 20 and the volute side panels 12 are arranged to form a volute enclosure, and at least part of the spliced ​​volute 20 is protrudingly arranged on the outside of the shell 10. This arrangement increases the overall volume of the box body and the volume of the fan, thereby increasing the air output of the ceiling appliance. The impeller 40 can selectively rotate in the counterclockwise direction and the clockwise direction, and the fan can discharge air from different air outlets, thereby facilitating the switching of the air outlet function and the ventilation function of the ceiling appliance. This arrangement reduces the difficulty of installing the ceiling appliance, solves the problem of low air output due to limited installation space of the prior art ceiling appliances, and effectively improves the practicality of the ceiling appliance. Among them, the position to be assembled can be the position when the spliced ​​volute 20 is installed on the ceiling board, or it can be the position when the spliced ​​volute 20 is received in the shell 10. Among them, the blades of the impeller 40 in this embodiment can adopt the following structure: two impellers (i.e., upper and lower layers of blades) are provided, and the directions of the blades of the first impeller and the second impeller are different (such as Figure 5 The impeller blades are straight; the impeller blade cross section is Y-shaped (called ram's horn blades).

[0060] Combine Figure 4 As shown, when the splicing volute 20 is in the blocking position, the splicing volute 20 is connected to the shell 10, and the splicing volute 20 blocks at least part of the opening 101. The position to be assembled includes a first position to be assembled. When the splicing volute 20 is in the first position to be assembled, the splicing volute 20 is separated from the shell 10 and installed on the installation base. The installation base can be a ceiling panel or a keel installed in the ceiling space. Among them, when the splicing volute 20 is in the blocking position, the splicing volute 20 can completely block the opening 101. Such an arrangement increases the air outlet of the ceiling electrical appliances while improving the sealing performance. In other embodiments of the present application, the splicing volute 20 can also block most of the opening 101, as long as most of the airflow can be blown out through the air duct 11.

[0061] Combine Figures 6 to 12As shown, the position to be assembled includes a second position to be assembled, and the splicing volute 20 is movably connected to the shell 10 so that the splicing volute 20 can be moved to the blocking position or the second position to be assembled, wherein when the splicing volute 20 is in the second position to be assembled, the splicing volute 20 is located in the shell 10. During installation, the splicing volute 20 is first moved to the second position to be assembled located in the shell 10, and the operating shell 10 is connected to the ceiling board or keel. After the connection is completed, the splicing volute 20 is moved to the blocking position, or the operating shell 10 is located in the ceiling space, the splicing volute 20 is moved to the blocking position, and then the shell 10 is connected to the ceiling board or keel, so that the ceiling appliance can be installed. This arrangement saves 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.

[0062] In order to achieve the connection between the splicing volute 20 and the shell 10, the splicing volute 20 is connected to the ceiling panel or keel and is located in the ceiling space so that the splicing volute 20 is located in the first assembly position. At this time, the splicing volute 20 is located above the shell 10. The operating shell 10 moves from the lower side of the installation opening opened on the ceiling panel to the ceiling panel toward the splicing volute 20. The shell 10 passes through the installation opening in the vertical direction and continues to move up in the vertical direction until the splicing volute 20 is in the blocking position (in the process of passing the shell 10 through the installation opening opened on the ceiling panel in the vertical direction, the shell 10 begins to contact and cooperate with the splicing volute 20 until the shell 10 moves to the mezzanine space where the splicing volute 20 is located. At this time, the splicing volute 20 is just in the blocking position). This arrangement allows the spliced ​​volute 20 to be installed to the assembly position first during installation, and then the shell 10 can be operated for further installation. This breaks through the problem of low air output due to limited installation space or installation port size in the existing ceiling appliances, makes the installation process more convenient, and effectively improves the practicality of the ceiling appliance.

[0063] Combine Figures 1 to 3 As shown, the ceiling appliance also includes a guide assembly 30, which is arranged along the height direction of the shell 10. The spliced ​​volute 20 is slidably connected to the shell 10 through the guide assembly 30 to achieve the switching of the spliced ​​volute 20 between the first assembly position and the blocking position, wherein 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 31 and the second guide member 32 is connected to the spliced ​​volute 20. 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. This arrangement makes the installation process of the shell 10 and the spliced ​​volute 20 more suitable for the installation of ceiling appliances, saving installation time and effort.

[0064] Combine Figure 2 and Figure 3 As shown, 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 blocking member 321 that cooperates with the groove 311. The blocking member 321 is preferably configured as a blocking plate, but can also be configured as a protruding structure, a slider, etc., as long as it can perform a sealing function.

[0065] Combine Figure 3 As shown, in this embodiment, the spliced ​​volute 20 includes a spliced ​​volute body 21, which extends along the length direction of the shell 10. Two spliced ​​volute side panels 22 are provided on both sides of the length direction of the spliced ​​volute body 21, and the two spliced ​​volute side panels 22 and the spliced ​​volute body 21 are arranged to form a spliced ​​body structure with a notch on one side, and the notch of the spliced ​​body structure is arranged toward the inside of the shell 10; wherein, the blocking member 321 is extended along the circumferential direction of at least part of the notch edge of the spliced ​​body structure. Such an arrangement can enclose a larger air duct 11 (compared to the prior art) by the spliced ​​volute 20 and the volute side panels 12, thereby expanding the corresponding volute air duct 113, thereby increasing the fan wheel and increasing the air supply capacity of the air duct 11. By adopting this solution, the air output of the ceiling appliance is increased while ensuring the stable air output of the ceiling appliance.

[0066] Combine Figure 3 As shown, in one embodiment of the present application, the sealing member 321 is arranged on two opposite sides in the height direction of the spliced ​​volute 20. This arrangement improves the performance of the fan while ensuring the sealing performance of the ceiling appliance and reduces the production cost, making the ceiling appliance more practical.

[0067] Combine Figure 2 and Figure 4 As shown, the edge of the opening 101 is provided with a groove 311 recessed toward the inside of the housing 10. When the spliced ​​volute 20 is in the blocking position, at least part of the blocking member 321 extends into the groove 311. This arrangement further improves the sealing performance of the ceiling appliance.

[0068] Combine Figure 2 As shown, at least one limiting section 102 is provided on the wall of the groove 311, forming a limiting space 103 between the limiting section 102 and the groove 311. When the spliced ​​volute 20 is in the blocking position, part of the blocking member 321 extends into the limiting space 103. This design ensures a tight seal between the spliced ​​volute 20 and the housing 10, preventing gas leakage and improving the performance and reliability of the ceiling appliance.

[0069] Combine Figure 1 and Figure 4As shown, the housing 10 includes an air collecting plate 13, and the air collecting plate 13 is provided with a mounting section 131, and the mounting section 131 is provided in cooperation with the spliced ​​volute 20. Such a setting further improves the installation stability and air outlet stability of the ceiling-mounted electrical appliance.

[0070] Furthermore, the air duct 11 has an air exchange port 111 and an air outlet 112. The air exchange port 111 and the opening 101 are relatively arranged on both sides of the shell 10, and the air collecting plate 13 is provided with an air outlet 112. When the impeller 40 can selectively rotate in the clockwise direction, the ceiling appliance takes in air from the air inlet of the air collecting plate 13 and exhausts air from the air outlet 112 (air outlet mode); when the impeller 40 can selectively rotate in the counterclockwise direction, the ceiling appliance takes in air from the air inlet of the air collecting plate 13 and exhausts air from the air exchange port 111 (ventilation mode). By providing a spliced ​​volute 20 with a blocking position and a position to be assembled and connected to the shell 10, the air volume of the fan is increased, thereby increasing the air volume in the air outlet mode and the ventilation mode, solving the problem of low air volume due to limited installation space in the prior art ceiling appliances, and effectively improving the practicality of the ceiling appliances.

[0071] The first guide member 31 and the second guide member 32 can be, but are not limited to, configured as a slider and a slide groove, a guide rail and a pulley, etc., as long as they can achieve sliding cooperation. Figures 6 and 7 As shown, in another embodiment of the present application, the ceiling appliance includes a sliding assembly 50, which is arranged along the width direction of the housing 10. The spliced ​​volute 20 is movably connected to the housing 10 via the sliding assembly 50, and the spliced ​​volute 20 slides to the blocked position or the second ready-to-assemble position via the sliding assembly 50. In other embodiments, the sliding assembly is arranged along the length direction of the housing 10.

[0072] The sliding assembly 50 includes a first sliding member 51 and a second sliding member 52. One of the first sliding member 51 and the second sliding member 52 is disposed on the housing 10, and the other of the first sliding member 51 and the second sliding member 52 is disposed on the splicing volute 20. The second sliding member 52 is slidably disposed along the length of the first sliding member 51, and the length of the first sliding member 51 is disposed along the width of the housing 10. This arrangement allows the splicing volute 20 to slide relative to the housing 10 to a blocked position or a second, ready-to-assemble position, making the ceiling appliance suitable for a variety of applications.

[0073] Furthermore, one of the first sliding member 51 and the second sliding member 52 is a guide rail, and the other of the first sliding member 51 and the second sliding member 52 is a slider matched with the guide rail, and the slider is slidably arranged along the length direction of the guide rail. Figures 6 and 7As shown, in a preferred embodiment of the present application, the ventilation port 111 and the opening 101 are respectively provided on the side panels of the housing 10, the guide rail is provided along the width direction of the housing 10, and the slider is slidably provided along the length direction of the guide rail. This arrangement enables the spliced ​​volute 20 to have a blocking position in which the guide rail and the slider cooperate to move away from one side of the housing 10 to the opening 101 to at least partially block the opening 101, and the spliced ​​volute 20 to have a second position to be assembled in the housing 10 in which the guide rail and the slider cooperate to move toward one side of the housing 10 until the spliced ​​volute 20 is completely received in the housing 10. The spliced ​​volute 20 can be moved to the blocking position and the second position to be assembled along the width direction of the housing 10, thereby increasing the scope of application of the ceiling appliance.

[0074] Combine Figure 8 and Figure 9 As shown, in another embodiment of the present application, the spliced ​​volute 20 is rotatably connected to the shell 10 through a rotating assembly 60, and the spliced ​​volute 20 is rotated to a blocked position or a second position to be assembled through the rotating assembly 60, wherein the rotation axis of the rotating assembly 60 is arranged close to the interior of the shell 10, and the rotation axis of the rotating assembly 60 is located in the air duct 11.

[0075] Furthermore, the rotating assembly 60 includes a first rotating member 61 and a second rotating member 62, one of which is connected to the housing 10, and the other of which is connected to the splicing volute 20. The second rotating member 62 is rotatably arranged relative to the first rotating member 61 so that the splicing volute 20 can be switched between a blocked position and a second position to be assembled. By providing the first rotating member 61 and the second rotating member 62, the splicing volute 20 is rotated relative to the housing 10, so that the splicing volute 20 can be switched between the blocked position and the second position to be assembled according to different usage scenarios, thereby increasing the air output while reducing the difficulty of installing the ceiling appliance.

[0076] In order to achieve the technical effect that the second rotating member 62 can rotate relative to the first rotating member 61, one of the first rotating member 61 and the second rotating member 62 is a rotating shaft 621, and the other of the first rotating member 61 and the second rotating member 62 is a sleeve 611 that matches the rotating shaft 621. The sleeve 611 is rotatably arranged along the circumference of the rotating shaft 621. This arrangement allows the spliced ​​volute 20 to be rotated relative to the shell 10 along the first preset direction to the second position to be assembled via the rotating shaft 621 and the sleeve 611 when installing the ceiling appliance. During operation, the spliced ​​volute 20 is rotated relative to the shell 10 along the second preset direction via the rotating shaft 621 and the sleeve 611 to be located in the blocking position. This allows the ceiling appliance to overcome the problem of low air output caused by installation space limitations while reducing the difficulty of installation, making the ceiling appliance suitable for more application scenarios.

[0077] Furthermore, a rotating shaft 621 is provided on the housing 10, and a sleeve 611 is provided on the spliced ​​volute 20. The axial direction of the rotating shaft 621 extends along the thickness direction of the housing 10. This arrangement allows the spliced ​​volute 20 to be rotated clockwise relative to the rotating shaft 621 to a second assembly position via the sleeve 611 when installing the ceiling appliance. During operation, the spliced ​​volute 20 is rotated counterclockwise relative to the rotating shaft 621 via the sleeve 611 to a blocked position. This allows the ceiling appliance to overcome the problem of low air output caused by installation space limitations, while also reducing the difficulty of installation and expanding the scope of application of the ceiling appliance.

[0078] Furthermore, the sleeve 611 is connected to the splicing volute 20 through a connector 23, and the connector 23 is one or more. By providing the connector 23, the splicing volute 20 is rotated in a preset direction relative to the rotating shaft 621 through the sleeve 611, so that the splicing volute 20 can switch between the blocking position and the second position to be assembled. Among them, the connector 23 can be a connecting rod or a connecting plate, as long as it can achieve a fixed connection between the sleeve 611 and the splicing volute 20. In a preferred embodiment of the present application, there are multiple connectors 23, and such a setting improves the connection stability between the sleeve 611 and the splicing volute 20, making the ceiling appliance more reliable in the process of switching between the blocking position and the second position to be assembled.

[0079] In other embodiments, the rotating assembly 60 is connected to the splicing volute 20, and the rotating assembly 60 can be installed on the mounting base. The splicing volute 20 is rotatably connected to the housing 10 via the rotating assembly 60 so that the splicing volute 20 is rotated to the blocking position. The splicing volute 20 is located in the first ready-to-assemble position via the rotating assembly 60.

[0080] In another embodiment of the present application, the spliced ​​volute 20 is detachably connected to the housing 10 by magnetic attraction. Figures 10 to 12 The ceiling appliance also includes at least one set of magnetic assemblies 70. Each set of magnetic assemblies 70 includes a first magnetic member 71 disposed on the housing 10 and a second magnetic member 72 disposed on the spliced ​​volute 20. The first magnetic member 71 is disposed near the opening 101. When the first magnetic member 71 and the second magnetic member 72 are engaged, the spliced ​​volute 20 is in a blocked position. This arrangement simplifies the connection between the spliced ​​volute 20 and the housing 10, allowing the ceiling appliance to switch between the blocked position and the ready-to-assemble position.

[0081] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0082] When installing the ceiling appliance, the spliced ​​volute 20 is installed in the position to be assembled, and then the spliced ​​volute 20 and the shell 10 are connected to the blocking position, so that the ceiling appliance overcomes the problem of low air output due to the limitation of the installation space or the installation port. When the spliced ​​volute 20 is in the blocking position, the spliced ​​volute 20 and the volute side plate 12 are arranged to form a volute enclosure, and at least part of the spliced ​​volute 20 is protruding from the outside of the shell 10. This arrangement increases the air output of the ceiling appliance. The impeller 40 can selectively rotate in the counterclockwise direction and the clockwise direction to realize the air outlet function and the ventilation function of the ceiling appliance, so as to increase the air output of the ceiling appliance in the working state and the ventilation air output during ventilation. This arrangement improves the sealing performance of the ceiling appliance and reduces the installation difficulty of the ceiling appliance, solves the problem of low air output due to limited installation space in the existing ceiling appliance, and effectively improves the practicality of the ceiling appliance.

[0083] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.
