It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill 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 thus their description will be omitted.

[0033] Combined with Figures 1 to 6 As shown, according to a specific embodiment of the present application, a housing assembly is provided.

[0034] Specifically, as Figures 1 to 3 shown, the housing assembly includes a housing 10 and an electrical component 20. The housing 10 is provided with a receiving cavity 12, and an opening 120 communicating with the outside of the housing 10 and the receiving cavity 12 is formed in the side wall of the receiving cavity 12. The electrical component 20 has an initial position and an installation position. When the electrical component 20 is in the initial position, the electrical component 20 is located in the receiving cavity 12. When the electrical component 20 is in the installation position, at least part of the electrical component 20 moves out of the housing 10 through the opening 120.

[0035] Applying the technical solution of this embodiment, the electrical component 20 has an installation position and an initial position. The accommodation cavity 12 is used to accommodate the electrical component 20 when it is inside the housing 10 (i.e., the electrical component 20 in the initial position). An opening 120 is formed on the side wall of the accommodation cavity 12, and the electrical component 20 can move in and out of the accommodation cavity 12 of the housing 10 through the opening 120. When the electrical component 20 is in the initial position, the electrical component 20 is received inside the accommodation cavity 12, saving the overall space of the housing assembly and facilitating the transportation and installation of the housing assembly. After the overall installation of the housing assembly, the electrical component 20 is switched to the installation position, which can avoid interference between the electrical component 20 and the high-voltage electricity inside the housing 10.

[0036] In an exemplary embodiment of the present application, the housing 10 has an air duct 11, and an accommodation cavity 12 is formed between the outer surface of a part of the air duct 11 and the side wall of the housing 10.

[0037] Optionally, the electrical component 20 includes at least one of an electronic control board assembly and a junction box. Electrical components such as the electronic control board assembly and the junction box are arranged on the electrical component 20 and are arranged outside the housing assembly together with the electrical component 20. The outside protects the wires, electrical components, and the electronic control board assembly through the junction box, and the inside blocks the opening 120 through the electrical component 20 to avoid strong electrical interference between the electrical components and the electronic control board assembly inside the junction box and the housing assembly.

[0038] Further, as Figure 3 shown, when the electrical component 20 is in the installation position, the electrical component 20 blocks the opening 120. When the electrical component 20 is in the installation position, since the opening 120 is blocked, the isolation between the electrical component 20 and the internal devices of the housing assembly is achieved. At this time, the electrical component 20 is outside the housing assembly, does not occupy the space inside the box, does not affect the size of the air duct 11 and the fan, nor does it affect the performance of the housing assembly. At the same time, it can also avoid interference between the electrical component 20 and the high-voltage electricity inside the housing assembly.

[0039] Those skilled in the art should understand that when the electrical component 20 is in the installation position, the opening 120 can also be partially blocked. Since the electrical component 20 is located in this installation position and is clamped or connected through corresponding connectors, the electrical component 20 can be stably separated from the inside of the housing assembly. When the housing assembly operates, the electrical component 20 will not affect the air output of the air duct 11 and the size of the housing assembly. At the same time, the electrical component 20 can avoid strong electrical interference with the inside of the housing assembly.

[0040] Optionally, the electrical component 20 is slidably connected to the housing 10 so that the electrical component 20 can be switched between the installation position and the initial position. The sliding connection method can make the position switching process of the electrical component 20 smoother and more convenient to operate.

[0041] Specifically, a slide rail structure can be provided on the housing 10 to facilitate the connection of the electrical component 20 to the housing 10 along the slide rail and slide relative to the housing 10.

[0042] Optionally, the electrical component 20 is hinged to the housing 10 so that the electrical component 20 can be rotated to the initial position or the installation position. The hinged connection method can make the structure of the electrical component 20 simpler, and the installation, disassembly and maintenance are more convenient.

[0043] In an exemplary embodiment of the present application, as Figures 1 to 6 shown, the rotation axis of the electrical component 20 extends along the height direction of the housing 10. When the opening 120 is provided on the side wall of the housing 10 instead of the bottom or top of the housing 10, it can cooperate with the opening 120 to realize the switching between the initial position and the installation position.

[0044] In an embodiment of the present application, the rotation axis of the electrical component 20 can also be extended along the width direction of the housing 10, that is, the electrical component can be switched between the initial position and the installation position in an up-and-down flipping manner through the hinged connection.

[0045] It should be noted that, in this embodiment, the height direction of the housing 10 is set to be consistent with the axial direction of the fan provided in the air duct 11.

[0046] Optionally, the opening 120 is provided on the side wall in the width direction of the housing 10, or the opening 120 is provided on the side wall in the length direction of the housing 10. Different accommodation cavities 12 can be set according to the different installation positions and sizes of the air duct 11, and then the opening 120 can be provided on the side with the largest contact area between the accommodation cavity 12 and the side wall, that is, the communication area between the opening 120 and the accommodation cavity 12 is set to be the largest, so that the electrical component 20 can have a larger installation space when it is in the installation position, and at the same time, the connection reliability of the electrical component 20 can be improved.

[0047] Furthermore, as Figures 4 to 6 shown, the housing 10 has an air duct 11, and the electrical component 20 is movably connected to at least one of the housing 10 and the air duct 11 through a motion mechanism 30. It should be noted that the electrical component 20 can be movably connected to the housing 10 through the motion mechanism 30, or can be movably connected to the air duct 11 through the motion mechanism 30, or can also be connected to both the housing 10 and the air duct 11 through the motion mechanism 30. When the electrical component 20 is connected to both the housing 10 and the air duct 11 through the motion mechanism 30, the reliability of the electrical component 20 can be improved, and the electrical component 20 can be prevented from falling off due to unstable connection when moving with the motion mechanism 30.

[0048] Specifically, the motion mechanism 30 includes a rotating shaft 31 and a connecting member 32. The rotating shaft 31 extends along the height direction of the housing 10 and is disposed in the accommodating cavity 12. One end of the connecting member 32 is movably connected to the rotating shaft 31, and the electrical component 20 is disposed on the connecting member 32. The connecting member 32 rotates about the axis of the rotating shaft 31 to switch the electrical component 20 between the initial position and the installation position. By disposing the electrical component 20 on the connecting member 32 and the connecting member 32 rotating about the rotating shaft 31, the electrical component 20 can rotate about the rotating shaft 31 together with the connecting member 32. When the electrical component 20 is in the initial position, it is possible to avoid disassembling the electrical component 20. It is only necessary to rotate the electrical component 20 and the connecting member 32 into the accommodating cavity 12, which can save the overall space of the housing assembly.

[0049] Specifically, as Figures 4 to 6 shown, the connecting member 32 includes a bent connecting plate 321 and a bearing plate 322. The first end of the bent connecting plate 321 is movably connected to the rotating shaft 31. The electrical component 20 is disposed on the bearing plate 322, and the bearing plate 322 is connected to the second end of the bent connecting plate 321. Wherein, when the electrical component 20 is in the installation position, the bearing plate 322 is disposed close to the opening 120 so that at least a part of the electrical component 20 extends outside the housing 10. By providing the connecting member 32 with the bent connecting plate 321, the size of the bent connecting plate 321 can be adjusted, and then the rotating shaft 31 can be disposed at different positions of the housing 10, that is, the rotating shaft 31 can be disposed close to or far from the opening 120. The bearing plate 322 is used to bear the weight of the electrical component 20, and at the same time the bearing plate 322 is used to block the opening 120. The bearing plate 322 needs to be set as a plate-like structure with a certain strength. Providing the connecting member 32 with the bent connecting plate 321 can more flexibly realize the connection between the electrical component 20 and the housing 10, and providing the connecting member 32 with the bearing plate 322 can improve the connection stability between the connecting member 32 and the opening 120 and the electrical component 20.

[0050] Specifically, the electrical component 20 is disposed on the side of the bearing plate 322 facing the outside of the housing 10 so that when the bearing plate 322 is close to the opening 120, the electrical component 20 can extend outside the housing 10 smoothly.

[0051] In an exemplary embodiment of the present application, as Figure 5As shown, the bent connection plate 321 includes a first plate segment 3211 and a second plate segment 3212. The first plate segment 3211 and the second plate segment 3212 are connected at an angle. One end of the first plate segment 3211 far from the second plate segment 3212 is connected to the rotating shaft 31, and one end of the second plate segment 3212 far from the first plate segment 3211 is connected to the bearing plate 322. Among them, there are multiple first plate segments 3211, and the multiple first plate segments 3211 are arranged at intervals along the axial direction of the rotating shaft 31. The first plate segment 3211 is arranged inside the accommodating cavity 12. When the electrical component 20 rotates with the moving mechanism 30, the first plate segment 3211 rotates inside the accommodating cavity 12. When the electrical component 20 is in the installation position, the second plate segment 3212 connected to the first plate segment 3211 moves to the opening 120, and the second plate segment 3212 is connected to the bearing plate 322. The electrical component 20 is carried on the bearing plate 322, and the electrical component 20 needs to be arranged protruding from the housing assembly at the opening 120. Then, setting the first plate segment 3211 and the second plate segment 3212 at an angle can make the second plate segment 3212 and the bearing plate 322 better adapt to the opening 120 and the electrical component 20. At the same time, arranging the multiple first plate segments 3211 at intervals along the axial direction of the rotating shaft 31 can improve the connection reliability between the bent connection plate 321 and the rotating shaft 31.

[0052] In this embodiment, the driving connection member 32 can be rotated relative to the rotating shaft 31 around the axis of the rotating shaft 31, so that the driving connection member 32 drives the electrical component 20 to switch between the installation position and the initial position.

[0053] In other embodiments, the connection member 32 and the rotating shaft 31 are fixedly connected. The rotating shaft 31 is connected to the output shaft of the driving motor. The driving motor drives the rotating shaft 31 to rotate, so that the axis of the rotating shaft 31 of the electrical component 20 rotates, and the electrical component 20 switches between the installation position and the initial position.

[0054] Further, a locking device is provided on the moving mechanism 30. The locking device has a locking state for locking the moving mechanism 30, and the locking device has a first release state for releasing the moving mechanism 30. The locking device can prevent the moving mechanism 30 and the electrical component 20 from shaking in the accommodating cavity 12, generating collisions and noises, and at the same time prevent the electrical component 20 from shifting after subsequent installation is completed.

[0055] Further, a first clamping member is provided on the electrical component 20, and a second clamping member is provided on the housing 10. The second clamping member and the first clamping member have a clamping state in which the housing 10 and the electrical component 20 are clamped, and the second clamping member and the first clamping member have a second release state in which the housing 10 and the electrical component 20 are released. Multiple first clamping members can be provided on the electrical component 20, and multiple second clamping members can also be provided on the housing 10. The multiple first clamping members and the second clamping members are provided in one-to-one correspondence. When the electrical component 20 is in the installation position, the housing 10 and the electrical component 20 are clamped, and the multiple first clamping members and the multiple second clamping members are correspondingly clamped. When the electrical component 20 is in the initial position, the housing 10 and the electrical component 20 are separated from each other, and the multiple first clamping members and the multiple second clamping members are correspondingly released.

[0056] Optionally, when the electrical component 20 is movably connected to the housing 10 through the motion mechanism 30, the first clamping member can also be provided on the motion mechanism 30. At this time, the first clamping member and the second clamping member have a clamping state in which the housing 10 and the motion mechanism 30 are clamped, and the first clamping member and the second clamping member have a second release state in which the housing 10 and the motion mechanism 30 are released. In addition, the first clamping member can also be provided on both the motion mechanism 30 and the electrical component 20 to improve the position stability of the electrical component 20.

[0057] It should be noted that the first clamping member and the second clamping member can be various structures such as a snap-slot structure, a claw-slot structure, a snap-hole structure, etc.

[0058] Further, the air duct 11 and the accommodation cavity 12 are provided independently of each other. This can avoid the influence of the electrical component 20 in the accommodation cavity 12 on the air duct 11. In this embodiment, the space inside the housing assembly is preferentially used to set the structure of the air duct 11 to improve the performance such as the air output of the housing assembly, and then the space of the accommodation cavity 12 is set to make full use of the space of the housing assembly.

[0059] Preferably, at least a part of the air duct 11 protrudes from the housing 10 in the width direction of the housing 10. By protruding the air duct 11 from the housing 10, the protruding part can increase the capacity of the air duct 11, thereby increasing the air output and improving the performance of the housing assembly.

[0060] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 6As shown in the figure, the air duct 11 includes an air duct body 111 and a spliced air duct 112. The air duct body 111 has a splicing opening, and the spliced air duct 112 has a blocking position for blocking at least part of the splicing opening, and, the spliced air duct 112 has an avoidance position away from the splicing opening. When the spliced air duct 112 is in the blocking position, at least part of the spliced air duct 112 protrudes from the housing 10 in the width direction of the housing 10. When the spliced air duct 112 is located at the avoidance position, the longitudinal space size of the housing assembly is not affected, which is convenient for installation; when the spliced air duct 112 is located at the blocking position, the spliced air duct 112 blocks the splicing opening and is connected to the housing 10. When applied to the electrical structure, it can effectively increase the air volume of the electrical appliance, adapt to the use environment with higher requirements for air volume, improve the practicability of the electrical appliance, and solve the problems of insufficient air volume and low practicability of the electrical appliance in the prior art.

[0061] Preferably, the spliced air duct 112 and part of the air duct body 111 form the volute of the fan, forming the internal air duct of the fan, expanding the air volume of the fan, and thus improving the air outlet performance of the housing assembly.

[0062] Those skilled in the art should understand that when the spliced air duct 112 is in the blocking position, the blocking position can block at least part of the splicing opening. Since the spliced air duct 112 is already in this position, that is, the capacity expansion of the air duct 11 is realized. When the housing assembly operates, the air volume can be expanded, and the performance of the housing assembly can be improved. In this embodiment, the setting of the spliced air duct 112 can increase the cross-sectional area of the air duct.

[0063] According to another specific embodiment of the present application, a ceiling electrical appliance is provided. The ceiling electrical appliance has a housing assembly, and the housing assembly is the housing assembly in the above embodiment. The ceiling electrical appliance includes, but is not limited to, devices such as kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, fresh air fans, exhaust fans, etc.

[0064] When the housing assembly in the above embodiment is applied to a ceiling electrical appliance, since the electrical component 20 and the moving mechanism 30 can block the opening 120 when located at the installation position, the separation of the electrical component 20 and the internal components of the housing assembly is realized, avoiding interference between the electrical component 20 and the strong electricity. At the same time, the spliced air duct 112 can protrude outwards to increase the cross-sectional area of the air duct 11, and the housing 10 can have a greater air volume, thereby making the air outlet effect of the ceiling electrical appliance better, more suitable for the environment with higher requirements for air volume, and improving the air outlet performance and practicability of the ceiling electrical appliance.

[0065] In one embodiment of the present application, the ceiling-mounted electrical appliance is a bathroom heater. The bathroom heater has the housing assembly in the foregoing embodiment. The housing 10 can be the outer housing of the bathroom heater main body. The air duct 11 can be separately formed by a volute side plate independently provided from the housing 10, or the volute side plate can be set as a plate-shaped structure. The volute side plate, the side wall of the housing 10, and the bottom plate of the housing enclose a blower volute and the air duct 11 corresponding to the blower.

[0066] When the housing assembly is applied to the bathroom heater, the electrical component 20 is arranged on the moving mechanism 30. The moving mechanism 30 can drive the electrical component 20 to block and avoid the opening 120 on the housing 10. When the electrical component 20 is in the installation position, the electrical component 20 is isolated from other components inside the bathroom heater, avoiding strong electrical interference of the electrical component 20. The spliced air duct 112 is protruded outwardly on the housing 10, increasing the cross-sectional area of the air duct 11 of the bathroom heater. Thus, without improving the sizes of the bathroom heater fan and the housing assembly, the housing 10 can have a greater air output, making the air output effect of the bathroom heater better.

[0067] For ease of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" etc. can be used here to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device shown in the figures. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0068] In addition to the above, it should also be noted that the "one embodiment", "another embodiment", "embodiment" etc. mentioned in this specification refer to the specific features, structures or characteristics described in connection with that embodiment being included in at least one embodiment generally described in the present application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a specific feature, structure or characteristic in connection with any one embodiment, it is intended that implementing such feature, structure or characteristic in connection with other embodiments also falls within the scope of the present invention.

[0069] In the above embodiments, the descriptions of each embodiment have their own focuses. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0070] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
