This application claims priority to the patent application filed on July 26, 2024, with China National Intellectual Property Administration, application number 202421805380.1, 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 electrical appliance is provided, comprising: a main unit housing having a first air duct; a fan unit having an outer casing having a second air duct formed inside the outer casing; wherein the fan unit has an assembly position for assembly with the main unit housing, wherein when the fan unit is in the assembly position, the fan unit is located outside the main unit housing, and the first air duct and the second air duct are connected to form a ventilation channel.

[0006] Furthermore, the fan unit has a disassembly position for separation from the main unit housing.

[0007] Furthermore, the fan unit is detachably connected to the main unit housing.

[0009] Furthermore, the main unit housing has an independently configured first cavity and a second cavity. The first cavity is provided with an air inlet, and the second cavity is provided with an air outlet. The first cavity forms a first air duct.

[0010] Furthermore, the second cavity forms another part of the first air duct, and both the first cavity and the second cavity have a first opening.

[0011] Furthermore, the first cavity and the second cavity are spaced apart along the length of the main unit housing.

[0012] Furthermore, the main unit housing includes a first enclosure and a second enclosure, with the first enclosure forming a first cavity and the second enclosure forming a second cavity.

[0013] Furthermore, a partition plate is provided inside the main unit housing, which divides the inner cavity of the main unit housing into a first cavity and a second cavity.

[0014] Furthermore, a volute is provided inside the outer shell, which forms a second air duct.

[0015] Furthermore, a third air duct is formed between the inner wall of the volute and the outer shell. When the outer shell is in the assembled position, the third air duct connects between the first air duct and the second air duct.

[0016] Furthermore, the connecting side of the outer casing is provided with a mating plate, which is arranged around the second opening, and the outer casing is connected to the side wall of the main casing through the mating plate.

[0033] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. 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.

[0034] Combination Figures 1 to 5 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.

[0035] Specifically, such as Figure 1 As 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. The fan unit 2 has an outer casing 21, and a second air duct 22 is formed inside the outer casing 21. The fan unit 2 has an assembly position when assembled with the main unit housing 1. When the fan unit 2 is in the assembly position, it is located outside the main unit housing 1, and the first air duct 11 and the second air duct 22 communicate to form a ventilation channel.

[0036] 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 via an outer casing. The fan unit 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.

[0037] It should be noted that in existing technologies, the duct section and fan section are the main structural components of ceiling electrical appliances, with the fan section occupying most of the space within the main unit housing, thus limiting the installation space for other related structural components. In this application, the fan section is located outside the main unit housing, providing ample installation space for other functional accessories of the ceiling electrical appliance. On the one hand, the size of the duct section is not limited by the main unit housing, allowing for the manufacture of ceiling electrical appliances with better performance. On the other hand, the installation space for additional functional components of the ceiling electrical appliance is significantly increased, which helps to improve the performance of these additional functions. Furthermore, the significantly increased installation space for additional functional components of the ceiling electrical appliance facilitates modular and standardized manufacturing of its various functional modules.

[0038] Furthermore, the fan unit 2 is located outside the main unit housing 1, which alleviates the internal space of the main unit housing 1, and the ventilation openings on the main unit housing 1 can be flexibly designed according to requirements.

[0039] Furthermore, 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, thereby improving the reliability of the equipment.

[0040] Furthermore, the fan unit has a disassembly position for separation from the main unit housing.

[0041] The fan unit has a detachable position, which means that the fan unit and the main unit housing can be installed independently. This allows the position of the fan unit to be adjusted according to the installation environment, thereby reducing the size restrictions on ceiling electrical appliances due to the installation space.

[0042] Preferably, the fan unit is detachably connected to the main housing so that the fan unit has a disassembly position and an assembly position, and is easy to switch between the two positions.

[0043] Furthermore, the first air duct is provided with an air inlet, an air outlet and a first opening, and the second air duct is provided with a second opening. When the outer casing is in the assembly position, the first air duct and the second air duct are connected through the first opening and the second opening to form a ventilation channel.

[0044] In one exemplary embodiment of this application, the main unit housing 1 has a first cavity 15 and a second cavity 16 that are independently provided. The first cavity 15 is provided with an air inlet 12, and the second cavity 16 is provided with an air outlet 13. The first cavity 15 forms a first air duct 11.

[0045] Preferably, the second cavity 16 forms another part of the first air duct 11, and both the first cavity 15 and the second cavity 16 are provided with a first opening 14.

[0046] Specifically, such as Figure 1 As shown, the main unit housing 1 has a receiving cavity with one open end, and the fan unit 2 is connected to the first side wall of the main unit housing 1. The receiving cavity of the main unit housing 1 is provided with a first cavity 15 and a second cavity 16. The air inlet 12 on the first cavity 15 is located near the open end of the main unit housing 1, and the first opening 14 on the first cavity 15 is located through the first side wall of the main unit housing 1. The air outlet 13 on the second cavity 16 is located near the open end of the main unit housing 1, and the first opening 14 on the second cavity 16 is located through the first side wall of the main unit housing 1. The first cavity 15 and the second cavity 16 together form a first air duct 11. When the fan unit 2 is in the assembly position, the first air duct 11 is connected to the second air duct 22 through the first opening 14. Specifically, under the suction force of the fan unit 2, indoor air enters the first cavity 15 through the air inlet 12, then flows into the second air duct 22 through the first opening 14, then enters the second cavity 16 through the second air duct 22, and finally flows back into the room from the air outlet 13 of the second cavity 16. A bracket 17 is provided at the air outlet 13 of the second cavity 16, and a thermistor (PTC) is installed on the bracket 17. The thermistor (PTC) is used to heat the airflow in the second cavity 16. A damper 18 is provided at the air outlet 13, which is used to close and open the air outlet 13.

[0047] Furthermore, such as Figure 1 As shown, the first cavity 15 and the second cavity 16 are spaced apart along the length of the main housing 1.

[0048] As an alternative implementation, the first cavity 15 and the second cavity 16 may be spaced apart along the height direction of the main housing 1.

[0049] Furthermore, the main unit housing 1 is provided with a first enclosure and a second enclosure, the first enclosure forming a first cavity 15, and the second enclosure forming a second cavity 16. Specifically, as shown... Figure 1 , Figure 5 As shown, both the first and second housings are rectangular shells, and are spaced apart along the length of the main unit housing 1. Both the first and second housings are independent of the main unit housing, meaning the first air duct is an independent module, which facilitates the internal installation layout of the main unit housing 1.

[0050] As an alternative implementation, the main unit housing 1 is provided with a partition plate that divides the inner cavity of the main unit housing 1 into a first cavity 15 and a second cavity 16. Specifically, the partition plate extends along the width direction of the main unit housing so that the first cavity 15 and the second cavity 16 are arranged along the length direction of the main unit housing 1.

[0051] In another exemplary embodiment of this application, a volute 24 is provided inside the outer casing 21, forming a second air duct 22. The design of the volute 24 can optimize the airflow path and reduce wind resistance.

[0052] Furthermore, a third air duct 25 is formed between the inner wall of the volute 24 and the outer shell 21. When the outer shell 21 is in the assembled position, the third air duct 25 connects the first air duct 11 and the second air duct 22. Specifically, as... Figure 4 As shown, the fan unit 2 is connected to the first sidewall of the main housing 1 via the second sidewall of the outer casing 21. The layout of the second air duct 22 and the third air duct 25 is designed according to the structure of the first air duct 11, that is, the second air duct 22 and the third air duct 25 are arranged sequentially along the length of the outer casing 21. The second opening 23 on the second air duct 22 penetrates the second sidewall of the outer casing 21 and is connected to the first opening 14 on the first cavity 15. The second opening 23 on the third air duct 25 penetrates the second sidewall of the outer casing 21 and is connected to the first opening 14 on the second cavity 16.

[0053] Figure 4 The arrows in the diagram represent the direction of airflow. Specifically, under the suction force of the fan unit 2, the indoor air enters the first cavity 15 through the air inlet 12, then enters the third air duct 25 through the first opening 14 and the second opening 23, then enters the second air duct 22 through the air inlet side of the volute 24, and then enters the second cavity 16 through the first opening 14 and the second opening 23, where it is heated. The heated airflow then flows into the room through the air outlet 13.

[0054] In another exemplary embodiment of this application, a mating plate 26 is provided on the connecting side of the outer casing 21. The mating plate 26 is arranged around the second opening 23, and the outer casing 21 is connected to the side wall of the main casing 1 through the mating plate 26.

[0055] Specifically, in combination Figure 2 , Figure 3 As shown, the mating plate 26 is disposed on the second side wall of the outer casing 21 and surrounds the second opening 23. A protrusion 27 is provided on one long side of the mating plate 26, and a connecting flange is provided at the open end of the main casing 1. The connecting flange has a insertion hole 19, and the protrusion 27 is inserted into the insertion hole 19 to initially position the main casing. A flange is provided on the other long side of the mating plate 26. After the protrusion 27 and the insertion hole 19 are inserted, the flange fits snugly against the main casing 1. Both the flange and the main casing 1 have mounting holes, and the flange is connected to the main casing 1 by screws.

[0056] During the installation of ceiling electrical appliances, the fan unit 2 is first installed to the installation foundation, and then the main unit housing 1 is moved to the installation foundation to connect with the fan unit 2.

[0057] The ceiling-mounted electrical appliance in the above embodiments is one of an air conditioner, a bathroom heater, and a fresh air system.

[0058] 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 the volute side plate of the air duct is formed in the housing, and the air duct and the housing are two independently set components. Of course, the volute side plate can also be set as a plate structure, and the air duct is formed between the volute side plate and the side wall and bottom plate of the housing. Specifically, an air collecting hood is provided on the side of the housing opposite to the bottom, and a panel is provided on the outer side of the air collecting hood. The lamp assembly is located on the side where the air collecting hood and the panel are located.

[0059] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0060] 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 through a housing 21.

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.

[0061] 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.

[0062] 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.
