This application claims priority to the patent application filed on July 26, 2024, with China National Intellectual Property Administration, application number 202421795613.4, entitled "A Ceiling Electrical Appliance". Background Technology

[0002] Common ceiling-mounted electrical appliances include air conditioners, bathroom heaters, and fresh air systems. Among these, bathroom heaters, as a commonly used indoor heating device, primarily function to raise the temperature of the bathroom by heating the air. Bathroom heaters typically consist of a housing, a fan, and a volute, with the size of the fan and volute closely related to the performance of the heater.

[0003] In existing technologies, attempts to improve the performance of bathroom heaters involve modifying the dimensions of the fan and casing to maximize their size. However, this approach is limited by the dimensions of the enclosure, which in turn are constrained by the size of the ceiling panels and the width of the joists. This limitation prevents the performance improvements from meeting users' high demands for enhanced bathroom heater performance. Utility Model Content

[0004] The main purpose of this utility model is to provide a ceiling-mounted electrical appliance to solve the technical problem of low air volume caused by limited installation space in the main unit casing of existing ceiling-mounted electrical appliances.

[0005] To achieve the above objectives, according to one aspect of the present invention, a ceiling-mounted electrical appliance is provided, comprising: a main unit housing having a first air duct, the first air duct having an air outlet and a first opening; a fan unit having a second air duct, the second air duct having an air inlet and a second opening; wherein the fan unit is detachably connected to the main unit housing, so that the fan unit has an assembly position connected to the main unit housing and a disassembly position separated from the main unit housing, the fan unit being in the assembly position, and the first air duct and the second air duct being connected through the first opening and the second opening to form a ventilation channel.

[0006] Furthermore, the main unit housing has at least one cavity, one of which is provided with an air outlet and a first opening, the cavity forming a first air duct.

[0007] Furthermore, the main unit housing contains a first housing, which has an air outlet and a first opening, forming a first air duct.

[0008] Furthermore, the main housing is provided with a limiting component. When the fan unit is in the assembly position, the limiting component cooperates with the fan unit to restrict the fan unit from separating from the main housing along the width direction and / or length direction of the main housing.

[0009] Furthermore, the fan unit slides into the limiting component, allowing the fan unit to move along the height direction of the main housing to the assembly position and the disassembly position.

[0010] Furthermore, the fan unit includes a docking plate. When the assembled fan unit is in the assembly position, the docking plate is fitted against the side wall of the main unit housing, and the fan unit slides with the limiting component through the docking plate.

[0011] Furthermore, the limiting component includes: a groove, which is disposed on the main housing and surrounds the first opening; when the fan part is in the assembly position, the mating plate extends into the groove along the height direction of the fan part, and the groove restricts the mating plate from moving along the length direction of the main housing.

[0012] Furthermore, the limiting component also includes: a limiting plate, which is disposed on the main housing and is positioned opposite to the groove, forming a limiting space between the limiting plate and the groove; when the fan unit is in the assembly position, the mating plate extends into the limiting space along the height direction of the main housing, and the limiting plate restricts the mating plate from moving along the width direction of the main housing.

[0013] Furthermore, the limiting component includes: a plug-in hole, which is provided on the connecting flange of the main housing and extends through the height direction of the main housing; when the fan unit is in the assembly position, the protrusion at the edge of the mating plate extends into the plug-in hole along the height direction of the fan unit, and the plug-in hole restricts the movement of the mating plate along the width and length directions of the main housing.

[0014] Furthermore, the edge of the mating plate is provided with a flange, which extends along the length of the mating plate and is set at an angle to the mating plate. When the fan part is in the assembly position, the flange is detachably connected to the main unit housing.

[0015] Furthermore, the fan unit includes: a volute, which forms a second air duct, with the inlet of the volute serving as an air inlet and the outlet of the volute serving as a second opening.

[0016] Furthermore, ceiling-mounted electrical appliances include air conditioners, bathroom heaters, and fresh air systems.

[0017] The ceiling-mounted electrical appliance, utilizing the technical solution of this utility model, includes a main unit housing and a fan unit. The fan unit is detachably connected to the main unit housing and is located outside the main unit housing. During installation, the position of the fan unit is controlled according to the installation environment, thereby achieving the splicing of the main unit housing and the fan unit. The size of the fan unit affects the airflow of the ceiling-mounted electrical appliance. Since the fan unit is located outside the main unit housing, its size is not limited by the size of the main unit housing. The size of the fan unit can be increased according to the installation environment and user needs to improve the airflow of the ceiling-mounted electrical appliance and meet user requirements. In the above-described solution, the fan unit is located outside the main unit housing to solve the problem of low airflow caused by insufficient installation space in the main unit housing.

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. 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.

[0035] Combination Figures 1 to 7 As shown in the figure, a structural schematic diagram of an embodiment of a ceiling electrical appliance is provided according to a specific embodiment of this application.

[0036] Specifically, such as Figure 1As shown, the ceiling electrical appliance includes: a main unit housing 1 and a fan unit 2. The main unit housing 1 has a first air duct 11, which has an air outlet 12 and a first opening 13. The fan unit 2 has a second air duct 21, which has an air inlet 22 and a second opening 23. The fan unit 2 is detachably connected to the main unit housing 1 so that the fan unit 2 has an assembly position connected to the main unit housing 1 and a disassembly position separated from the main unit housing 1. The fan unit 2 is located in the assembly position, and the first air duct 11 and the second air duct 21 are connected through the first opening 13 and the second opening 23 to form a ventilation channel.

[0037] In the embodiments of this application, the ceiling-mounted electrical appliance includes a main unit housing and a fan unit. The fan unit is detachably connected to the main unit housing and is located outside the main unit housing. During installation, the position of the fan unit is controlled according to the installation environment, thereby achieving the splicing of the main unit housing and the fan unit. The size of the fan unit affects the airflow of the ceiling-mounted electrical appliance. Since the fan unit is located outside the main unit housing, its size is not limited by the size of the main unit housing. The size of the fan unit can be increased according to the installation environment and user needs to improve the airflow of the ceiling-mounted electrical appliance and meet user requirements. The ceiling-mounted electrical appliance in the above solution places the fan unit outside the main unit housing to solve the problem of low airflow caused by insufficient installation space in the main unit housing.

[0038] Furthermore, the fan unit 2 is located outside the main unit housing 1, effectively solving the problem of the fan size being limited by the internal space of the main unit housing 1. This technical solution allows for maximizing the size of the fan unit 2, thereby increasing the airflow of the ceiling-mounted electrical appliances. The ventilation openings on the main unit housing 1 can be flexibly designed according to requirements.

[0039] The power supply for the fan unit 2 and the power supply for the main unit housing 1 are set independently, which can improve the reliability of the ceiling electrical appliances and facilitate separate maintenance and cleaning of the fan unit 2 and the main unit housing 1.

[0040] In one exemplary embodiment of this application, the main unit housing 1 has at least one cavity, one of which is provided with the air outlet 12 and the first opening 13, and the cavity forms the first air duct 11. This arrangement makes the main unit housing structure simple, effectively utilizes the internal space of the housing, and increases the air volume of the air duct.

[0041] Furthermore, the main unit housing 1 is provided with a first housing 14, the first housing 14 is provided with an air outlet 12 and a first opening 13, and the first housing 14 surrounds to form a first air duct 11. The main unit housing 1 is provided with a first housing 14, the first housing 14 is provided with the air outlet 12 and the first opening 13, and the first housing 14 surrounds to form the first air duct 11.

[0042] Furthermore, the main housing 1 is provided with a limiting component. When the fan unit 2 is in the assembly position, the limiting component cooperates with the fan unit 2 to prevent the fan unit 2 from separating from the main housing 1 along the width and / or length direction. This ensures the fixation and connection between the fan unit 2 and the main housing after installation, enhancing the safety and stability of the equipment.

[0043] In one exemplary embodiment of this application, the fan unit 2 is slidably engaged with the limiting component, allowing the fan unit 2 to move along the height direction of the main housing 1 to an assembly position and a disassembly position. Specifically, the fan unit 2 and the limiting component employ a sliding engagement design. During installation and disassembly, the fan unit 2 can move along the height direction of the main housing 1, and the limiting component allows the fan unit 2 to move from the assembly position to the disassembly position or vice versa when necessary. This effectively simplifies the assembly and disassembly process and improves the operating efficiency of the equipment.

[0044] Furthermore, the fan unit 2 includes a docking plate 24. When the assembled fan unit 2 is in the assembly position, the docking plate 24 is fitted against the side wall of the main housing 1, and the fan unit 2 slides with the limiting component through the docking plate 24. When the assembled fan components are in the assembly position, the docking plate 24 is fitted against the side wall of the main housing 1 to ensure a stable connection during fan installation. The design of sliding the fan unit 2 with the limiting component through the docking plate 24 allows the fan unit 2 to move relatively freely along the height direction of the main housing 1 for assembly and disassembly.

[0045] Specifically, the limiting component includes a groove 15, which is disposed on the main housing 1 and surrounds the first opening 13. When the fan unit 2 is in the assembly position, the mating plate 24 extends into the groove 15 along the height direction of the fan unit 2, and the groove 15 restricts the movement of the mating plate 24 along the length direction of the main housing 1. When the fan unit 2 is in the assembly position, the mating plate 24 extends into the groove 15 along the height direction of the fan unit 2. The design of the groove 15 ensures that the mating plate 24 is accurately inserted and fixed during the assembly process, avoiding movement or detachment due to errors or vibrations. The limiting design of the groove 15 ensures that the fan unit 2 can be firmly fixed in the correct position after assembly.

[0046] Furthermore, the limiting component also includes a limiting plate 16, which is disposed on the main housing 1. The limiting plate 16 is disposed opposite to the groove 15, and a limiting space is formed between the limiting plate 16 and the groove 15. When the fan part 2 is in the assembly position, the docking plate 24 extends into the limiting space along the height direction of the main housing 1, and the limiting plate 16 restricts the docking plate 24 from moving along the width direction of the main housing 1.

[0047] Furthermore, the limiting component includes a plug-in hole 17, which is provided on the connecting flange 18 of the main housing 1 and extends through the height direction of the main housing 1. When the fan unit 2 is in the assembly position, the protrusion 25 at the edge of the mating plate 24 extends into the plug-in hole 17 along the height direction of the fan unit 2, and the plug-in hole 17 restricts the movement of the mating plate 24 along the width and length directions of the main housing 1. In an exemplary embodiment of this application, the edge of the mating plate 24 is provided with a flange 26, which extends along the length direction of the mating plate 24 and forms an angle with the mating plate 24. When the fan unit 2 is in the assembly position, the flange 26 is detachably connected to the main housing 1. This design allows the edge to extend along the length direction of the mating plate 24, and the flange 26 forms an angle with the mating plate 24, which helps to enhance the rigidity and connectivity of the structure. When the fan unit 2 is in the assembly position, the flange 26 is designed to be detachably connected to the main housing 1, further improving the operability and flexibility of the equipment.

[0048] Furthermore, the fan unit 2 includes a volute 27, which forms a second air duct 21. The inlet of the volute 27 serves as an air inlet 22, and the outlet of the volute 27 serves as a second opening 23. The design of the volute 27 optimizes the airflow path and reduces wind resistance.

[0049] The ceiling-mounted electrical appliance in the above embodiments is one of an air conditioner, a bathroom heater, and a fresh air system.

[0050] Specifically, in a specific embodiment of this application, a bathroom heater is provided, wherein the housing is the outer shell of the bathroom heater main unit, and a volute side plate of the air duct is formed in the housing, with the air duct and housing being two independently disposed components. Alternatively, the volute side plate can be configured as a plate-like structure, with the volute side plate, the side wall of the housing, and the bottom plate forming an air duct. Specifically, an air collector shroud is provided on the side of the housing opposite to the bottom, and a panel is provided on the outer side of the air collector shroud. The lamp assembly is disposed on the side where the air collector shroud and the panel are located.

[0051] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0052] 1. The ceiling electrical appliance includes a main unit housing 1 and a fan unit 2. The fan unit 2 is detachably connected to the main unit housing 1. The fan unit 2 is located outside the main unit housing. The size of the fan unit 2 is not limited by the size of the main unit housing. The size of the fan unit can be increased according to the installation environment and user needs to improve the air volume of the ceiling electrical appliance, so as to meet user needs and solve the problem of low air volume caused by the installation space of the main unit housing.

[0053] 2. The fan unit 2 is located outside the main unit housing 1, which relieves the internal space of the main unit housing 1. The ventilation openings on the main unit housing 1 can be flexibly designed according to requirements.

[0054] 3. The power supply of the fan unit 2 and the power supply of the main unit housing 1 are set independently. When the power supply line of the main unit housing 1 fails, the fan unit 2 can continue to work, thus improving the reliability of the equipment.
