Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a ceiling-mounted electrical appliance with a maintenance function. Background Art

[0002] Yuba, also known as bathroom heater, is a ceiling appliance that can deliver airflow to the room to heat, insulate or renew the indoor air, along with ventilation fans and fresh air blowers. Taking Yuba as an example, based on the traditional Yuba, the existing Yuba also includes a maintenance lamp, which is used to emit maintenance light to radiate energy to human skin and perform skin care treatment, thereby producing beauty and recuperation effects. Existing Yuba usually adopts a design in which the maintenance lamp is fixedly installed on the body panel, which results in the maintenance light beam shape and beam irradiation range being single and non-adjustable, and the spot area formed by the beam is fixed, which cannot meet the user's diverse needs for beam shape and beam irradiation range. Utility Model Content

[0003] In view of this, the utility model provides a ceiling appliance with a maintenance function, which allows the shape of the maintenance light beam and the irradiation range of the light beam to be changed, and can meet the diverse needs of users for the shape of the light beam and the irradiation range of the light beam.

[0004] The utility model provides a ceiling appliance with a maintenance function, comprising a body, a maintenance lamp and a driving assembly. The body has a displacement space, which runs through a side of the body facing the indoor room to form a light outlet. The maintenance lamp can be movably arranged in the displacement space, and comprises a light-emitting portion arranged toward the indoor room through the light outlet. The driving assembly comprises a shifter connected to the maintenance lamp, and the shifter is used to drive the maintenance lamp to move closer to and away from the indoor room.

[0005] Compared with the prior art, the utility model has the following beneficial effects:

[0006] The shape of the maintenance light beam emitted by the maintenance lamp changes as the shifter drives the maintenance lamp to move relative to the body. The movement of the maintenance lamp relative to the body causes the distance between the light-emitting part and the side of the body facing the indoor room and having a light outlet to change. The proportion of the maintenance light irradiated to the inner wall of the displacement space and the maintenance light emitted from the light outlet to the indoor room are changed, so that the irradiation range of the maintenance light beam expands as the maintenance lamp approaches the indoor room and shrinks as the maintenance lamp moves away from the indoor room. Therefore, the utility model can form maintenance light beams of various shapes and irradiation ranges, can meet the user's diverse needs for beam shape and beam irradiation range, and obtain different maintenance and beauty effects.

[0007] In one embodiment, the fuselage includes a reflective wall, and the inner side wall of the displacement space forms at least a portion of the reflective wall and is used to reflect the maintenance light of the maintenance lamp toward the outside of the light outlet.

[0008] Such an arrangement can increase the proportion of maintenance light emitted from the light outlet into the room, so that more energy radiated by the maintenance lamp can be absorbed and utilized by the human body.

[0009] In one embodiment, the inner side wall of the displacement space extends from the bottom wall of the displacement space to the side of the body facing the interior of the room, and the inner side wall of the displacement space relatively far from the light outlet forms the bottom wall of the displacement space.

[0010] With such arrangement, the reflective wall is easy to form and has a larger reflective area, and the maintenance light irradiated on the inner wall of the displacement space can be reflected out of the light outlet.

[0011] In one embodiment, the maintenance lamp includes a light-emitting body and a light-expanding reflective wall. The light-expanding reflective wall is recessed in a direction away from the indoor room, and the light-emitting body is arranged on a side of the light-expanding reflective wall relatively close to the indoor room.

[0012] With such an arrangement, the maintenance light emitted by each light source can form a light beam propagating in a specific direction under the reflection effect of the light-expanding reflection wall, thereby improving the concentration of the maintenance light energy so that as much energy as possible can be propagated into the room along the specific direction and absorbed by human skin.

[0013] In one embodiment, the number of light-emitting bodies and light-diffusing reflective walls is configured to be at least one, and the two correspond one to one. Each light-emitting body includes an optical axis. There is a light-diffusing spacing between the light-diffusing reflective wall and the optical axis of the corresponding light-emitting body, and the light-diffusing spacing tends to increase in the direction approaching the indoor room.

[0014] With such arrangement, the maintenance light emitted by the luminous body approximately forms a parallel light beam under the reflection effect of the light-expanding reflection wall, and the energy propagation direction is more concentrated and unified.

[0015] In one embodiment, the shifter includes a driving member, an output member connected to the driving member and movably arranged on the fuselage, the maintenance light is connected to the output member, the driving member is used to drive the output member to move up and down, and the moving trajectory of the output member is not parallel to the side of the fuselage facing the room.

[0016] With such an arrangement, when the maintenance lamp moves relative to the fuselage, the distance between the light-emitting part and the side of the fuselage facing the indoor room and having a light outlet can be ensured to change, thereby ensuring that the ratio of the maintenance light irradiating the inner wall of the displacement space and the maintenance light emitted from the light outlet into the indoor room changes.

[0017] In one embodiment, the moving track of the output member is perpendicular to the side of the body facing the indoor room; and / or,

[0018] The maintenance lamp comprises a peripheral edge, at least a portion of which is slidably fitted with at least a portion of the inner wall of the displacement space; and / or,

[0019] The driving member includes a gear, and the output member includes a rack meshed with the gear. The rack is movably arranged on the body along a preset moving track, and the length direction of the rack is consistent with the extension direction of the preset moving track.

[0020] With such arrangement, the moving trajectory of the output member is shorter, and the driving member can drive the output member and the maintenance lamp to the desired position more quickly. The sliding adaptation between the peripheral edge and the inner wall can ensure that the maintenance lamp moves accurately along the moving trajectory following the output member, preventing the maintenance lamp from changing its posture at the same time and causing the direction of the light-emitting part to change. The shifter adopts a rack and pinion transmission form to significantly improve the position change accuracy of the maintenance lamp, thereby realizing precise control of the shape of the maintenance light beam and the irradiation range of the beam.

[0021] In one embodiment, the body includes a bottom plate facing the room and a limiting portion provided on the bottom plate, the bottom plate is provided with a light outlet, and the limiting portion is used to stop the shifter and / or the maintenance lamp.

[0022] With such a configuration, the limit portion can restrict the maintenance lamp from leaving the displacement space, thereby preventing the maintenance lamp from detaching from the fuselage, ensuring that the maintenance lamp and the fuselage always remain connected and adapted. The maintenance lamp is integrated into the fuselage, which also makes the installation of the heater with maintenance function simpler, faster and more time-saving, and reduces the operating steps of installing the maintenance lamp separately to the fuselage.

[0023] In one embodiment, the fuselage includes a first chassis with an air dispatching unit, a second chassis installed on the first chassis, the second chassis includes a bottom plate, and a displacement space is opened, and the displacement space runs through a side of the second chassis away from the bottom plate.

[0024] With such arrangement, the displacement space penetrates through the side of the second chassis away from the bottom plate to form an entry port, thereby allowing the maintenance lamp to be placed into the displacement space from the entry port and connected and adapted to the body, making the assembly of the ceiling appliance with maintenance function easier.

[0025] In one embodiment, the first chassis and the second chassis are stacked, and a side of the second chassis away from the bottom plate is connected to a side of the first chassis relatively close to the room.

[0026] In one embodiment, the displacement space includes a heat dissipation space located on the side of the maintenance lamp relatively away from the indoor room, the heat dissipation space is connected to the air intake end of the air dispatching unit, and the fuselage is provided with a conveying channel connecting the heat dissipation space and the outside of the fuselage.

[0027] Such a setting can also take into account the heat dissipation and cooling needs of the maintenance lamp. The heat generated after the maintenance lamp is turned on can be driven away from the heat dissipation space by the fluid entering the delivery channel, and then the heat can enter the air intake end together with the air, avoiding overheating of the heat dissipation space and affecting the performance and service life of the maintenance lamp.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0037] Traditional heaters are used to deliver warm air to the room to heat or keep the room warm. Most heaters are installed in bathrooms to heat or keep the bathroom warm. Based on traditional heaters, some improved heaters also include maintenance lamps, which are also called beauty lamps. They are devices that can generate maintenance light and sterilize and maintain the skin through the energy of the maintenance light, thereby achieving beauty and recuperation effects.

[0038] The utility model provides a ceiling appliance 100 with a maintenance function. In some embodiments, the ceiling appliance 100 with a maintenance function is a heater equipped with a maintenance lamp 20; in other embodiments, the ceiling appliance 100 with a maintenance function is a ventilator equipped with a maintenance lamp 20 or a fresh air fan equipped with a maintenance lamp 20.

[0039] The utility model does not particularly limit the installation and use occasions of the ceiling-mounted electrical appliance 100 with a maintenance function, and it can be used in a bathroom or in other indoor spaces.

[0040] The following introduces the ceiling appliance 100 with maintenance function by taking a heater used in a bathroom and equipped with a maintenance lamp 20 as an example. The ceiling appliance 100 with maintenance function includes a body 10, a maintenance lamp 20 and a driving component 30, and has both maintenance and beauty functions and indoor heating and insulation functions. When the ceiling appliance 100 with maintenance function is installed and used in a bathroom, the body 10 can be arranged in the ceiling space formed between the bathroom ceiling and the ceiling board.

[0041] The body 10 has a bottom side 111 for being placed indoors, and a displacement space 12 is formed inside the body 10. The displacement space 12 penetrates the bottom side 111 of the body 10 to form a light outlet 112 open to the indoors. Figure 1 , Figure 3 to Figure 5 In some embodiments, the body 10 includes a bottom plate 11 for forming at least a portion of a bottom side 111 , the displacement space 12 is formed on a side of the bottom plate 11 relatively away from the room, and the bottom plate 11 is provided with the light outlet 112 .

[0042] Optionally, when the fuselage 10 is arranged in place in the ceiling space, the side of the bottom plate 11 facing the room is a horizontal plane and forms at least a portion of the bottom side 111 .

[0043] Furthermore, in some embodiments, the ceiling appliance 100 with a maintenance function also includes an air dispatching unit 40, which is used to perform air transfer dispatching between the indoors and the inside of the body 10, and between the indoors and the outdoors, and includes a wind-repelling component and an air duct 42. The wind-repelling component is used to drive and accelerate the air entering the body 10 to form an airflow, and the air duct 42 provides a flow path for the flow of the airflow. The body 10 is also provided with an air outlet connected to the air duct 42 and open to the indoor, so that the airflow in the air duct 42 can flow into the indoor.

[0044] Optionally, in some embodiments, the ceiling appliance 100 with maintenance function also includes a heating device, which can be arranged at the air outlet, or in the air duct 42 or the wind-driving component. The heating device is used to heat the airflow driven by the wind-driving component to obtain a hot airflow or a warm airflow. The hot airflow can heat the bathroom, and the warm airflow can achieve heat preservation of the bathroom.

[0045] Optional, see Figure 1 , Figure 3 to Figure 5 When the ceiling appliance 100 with a maintenance function is a ventilator equipped with a maintenance lamp 20, the wind-expelling component can be a centrifugal fan 41, which includes an air inlet end 411 and an air outlet end arranged in an air duct 42. The body 10 is also provided with an air inlet connected to the room, thereby establishing an air inlet channel between the air inlet end 411 and the room. After the centrifugal fan 41 is started, the indoor air flows into the air inlet channel through the air inlet, and then enters the air inlet end 411. The air is accelerated by the centrifugal fan 41 and flows from the air outlet end to the air duct 42, and finally flows out of the air outlet.

[0046] When the ceiling appliance 100 with a maintenance function is a fresh air blower equipped with a maintenance lamp 20, the air inlet is connected to the outdoors, thereby establishing a fresh air passage between the air inlet end 411 and the outdoors, and the wind drive component can inhale fresh air from the outdoors and supply it to the indoors; when the ceiling appliance 100 with a maintenance function is a heater equipped with a maintenance lamp 20, the air inlet can be connected to at least one of the indoors and the outdoors.

[0047] The maintenance lamp 20 is movably disposed in the displacement space 12, and includes a light emitting portion 201 for emitting maintenance light to radiate energy to human skin. Figure 1 , Figure 3 to Figure 5 The light emitting portion 201 is located on a side of the curing light that is relatively close to the indoor space and the ground, and the light emitting portion 201 is at least partially exposed to the indoor space through the light outlet 112 .

[0048] Optionally, when the body 10 is arranged in place in the ceiling space, the graphics of the light-emitting portion 201 projected on the horizontal plane are all located within the graphics of the light outlet 112 projected on the horizontal plane, so that the light-emitting portion 201 is all directed toward the room through the light outlet 112 and is fully exposed to the room.

[0049] Specifically, see Figure 2 The maintenance lamp 20 includes a lamp board 22 and a light-emitting body 21 arranged on the side of the lamp board 22. The light-emitting body 21 can be one or more. The multiple light-emitting bodies 21 can be randomly dispersed on the side of the lamp board 22, or arranged in a queue or array on the side of the lamp board 22. The light-emitting part 201 includes the light-emitting body 21 and the side of the lamp board 22 on which the light-emitting body 21 is arranged; in addition, the maintenance lamp 20 also includes a backlight part 202, which is arranged back to back with the light-emitting part 201, specifically including the side of the lamp board 22 away from the light-emitting body 21.

[0050] Further, see again Figure 2 In some embodiments, the maintenance lamp 20 further includes a lens 23, which is disposed on the side of the lamp panel 22 where the light-emitting body 21 is disposed. The number of lenses 23 and the light-emitting body 21 are equal and one-to-one corresponding. The lens 23 is used to reflect and refract the maintenance light emitted by the light-emitting body 21 and change the direction of the maintenance light so that the maintenance light beam and energy are more concentratedly propagated in a direction close to the room and the ground.

[0051] Specifically, a light-expanding reflective wall 231 is formed on a portion of the surface of the lens 23, and the light-expanding reflective wall 231 is recessed in a direction away from the indoor room and the ground. The light-emitting body 21 is arranged on a side of the light-expanding reflective wall 231 that is relatively close to the indoor room and the ground. If the light-expanding reflective wall 231 is regarded as a thin-walled structure alone, the light-expanding reflective wall 231 is recessed in a direction away from the indoor room and the ground to form a groove, and the light-emitting body 21 is located in the groove. The maintenance light emitted by the light-emitting body 21 is reflected by the light-expanding reflective wall 231, thereby forming a conical light beam or a light beam approximately in a columnar shape that propagates toward the indoor room and the ground.

[0052] Assuming that any light-emitting body 21 has an optical axis, which is a straight line passing through the light-emitting body 21 and perpendicular to the light board 22, there is a light-expanding spacing between the concave side of the light-expanding reflecting wall 231 and the optical axis of the light-emitting body 21 corresponding to the light-expanding reflecting wall 231, and the light-expanding spacing tends to increase in the direction approaching the indoor room and the ground, wherein the groove of the light-expanding reflecting wall 231 refers to the side of the light-expanding reflecting wall 231 that is relatively close to the indoor room and the ground.

[0053] It can be understood that in other embodiments, a concave mirror can be used instead of the lens 23 to form a light-diffusing reflective wall 231. The number of concave mirrors is equal to and corresponds to the light-emitting bodies 21. The position of the concave mirror is configured so that the concave surface faces the room and the ground, and then the light-emitting body 21 is placed in the concave cavity of the concave mirror, so that the concave surface can form the light-diffusing reflective wall 231.

[0054] The driving assembly 30 includes a shifter 301 connected to the maintenance lamp 20. The shifter 301 is used to drive the maintenance lamp 20 to move closer to the room and the ground, and to drive the maintenance lamp 20 to move away from the room and the ground. When the maintenance lamp 20 moves relative to the fuselage 10, at least a part of the maintenance lamp 20 is always kept in the displacement space 12. When the fuselage 10 is arranged in place in the ceiling space, the maintenance lamp 20 is driven by the shifter 301 to change its height in the vertical direction.

[0055] Compared with the prior art, the utility model not only enables at least a part of the light-emitting part 201 to emit maintenance light into the room through the light outlet 112, but also can utilize the opening edge of the light outlet 112 and the inner wall 121 of the displacement space 12 to block part of the maintenance light. The blocked maintenance light is irradiated on the inner wall 121 of the displacement space 12, so the shape and irradiation range of the maintenance light beam are constrained by the light outlet 112 and the inner wall 121 of the displacement space 12. As the shifter 301 drives the maintenance lamp 20 to move up and down, the distance from the light-emitting part 201 to the bottom side 111 where the light outlet 112 is provided changes, which means that when the maintenance lamp 20 is in different positions in the displacement space 12, the shape and irradiation range of the maintenance light beam emitted from the light outlet 112 are different successively.

[0056] See also Figure 3 and Figure 4 , compared to Figure 3 The status shown, Figure 4 In the state shown, the maintenance lamp 20 is further closer to the room and the ground, the distance between the light emitting portion 201 and the bottom side 111 is reduced, the maintenance light irradiated to the inner wall 121 of the displacement space 12 is reduced, and accordingly, the proportion of the maintenance light emitted from the light outlet 112 to the room to form a light beam is increased. Figure 3 The status shown, Figure 4 In the state shown, the constraints of the light outlet 112 and the inner wall 121 of the displacement space 12 on the curing light are weakened, the irradiation range of the curing light beam is expanded, and the shape of the curing light beam is changed to be closer to a cone beam. Figure 3 The beam irradiation range in the shown state is relatively small, and the shape of the beam is closer to a column.

[0057] Specifically, the shifter 301 includes a driving member 31 and an output member 32, the output member 32 is connected to the driving member 31 and is movably arranged on the fuselage 10, the maintenance lamp 20 is connected to the output member 32, and the driving member 31 is used to drive the output member 32 to move up and down relative to the fuselage 10 along a preset moving trajectory that is not parallel to the bottom side 111, so that the maintenance lamp 20 follows the output member 32 to rise relative to the fuselage 10 to move away from the room, or follows the output member 32 to descend relative to the fuselage 10 to move closer to the room.

[0058] See also Figure 1 , Figure 3 to Figure 5 In some embodiments, the driving member 31 includes a driving motor and a gear 311 connected to the output shaft of the driving motor, the output member 32 includes a rack 321 meshing with the gear 311, the rack 321 is slidably disposed on the fuselage 10 along a preset moving trajectory, the preset moving trajectory is a straight line trajectory perpendicular to the bottom plate 11 and the bottom side 111, the length direction of the rack 321 is consistent with the extension direction of the preset moving trajectory, and the light board 22 is fixedly connected to the rack 321.

[0059] It is understandable that in other embodiments, the preset movement trajectory may also form a non-90° angle with the bottom side 111 , or may be a curved trajectory, as long as the output member 32 can change in vertical height during movement along the preset movement trajectory.

[0060] Optional, see Figure 3-4 When the output member 32 is driven by the driving member 31 to the first extreme position farthest from the room and the ground so that the vertical height of the maintenance lamp 20 reaches the highest, and when the output member 32 is driven by the driving member 31 to the second extreme position farthest from the room and the ground so that the vertical height of the maintenance lamp 20 reaches the lowest, the maintenance lamp 20 is located in the displacement space 12. When the output member 32 is in the second extreme position, the light-emitting portion 201 does not protrude from the bottom side 111. Preferably, the light-emitting portion 201 is flush and coplanar with the bottom side 111 at this time.

[0061] Furthermore, at least part of the peripheral edge 221 forms a relatively slidable clearance fit with the inner side wall 121 of the displacement space 12, and the peripheral edge 221 refers to the edge of the lamp board 22, that is, the surface of the lamp board 22 except the side with the light emitting body 21 and the side away from the light emitting body 21. In this way, it can be ensured that the maintenance lamp 20 follows the output member 32 for precise displacement, and prevents the maintenance lamp 20 from changing its posture and thus changing the direction of the light emitting part 201. The inner wall surface of the displacement space 12 includes the bottom wall and the inner side wall 121, and the bottom wall is relatively far away from the bottom side 111 and faces the room through the light outlet 112.

[0062] Optional, see Figure 1 , Figure 3 to Figure 5The lamp board 22 is a horizontally arranged flat plate structure. One side of the lamp board 22 where the light-emitting body 21 is arranged and the other side away from the light-emitting body 21 are parallel to each other. Both are horizontally extended rectangular plate surfaces. Therefore, the maintenance lamp 20 is always parallel to the horizontal direction when following the lifting movement of the output member 32. The displacement space 12 is a rectangular space. The inner side wall 121 of the displacement space 12 is perpendicular to the bottom side 111 and the horizontal direction. The bottom wall of the displacement space 12 is a plane parallel to the bottom side 111 and the horizontal direction.

[0063] Of course, in other embodiments, the driving member 31 and the output member 32 can also use other transmission mechanisms to replace the gear 311 and rack 321 mechanism to realize the lifting and lowering drive of the maintenance lamp 20. For example, a push rod motor can be used to replace the gear 311 and rack 321 mechanism. The push rod of the push rod motor is used to form the output member 32. The lamp board 22 is connected to the push rod. The length direction of the push rod and the telescopic movement direction of the push rod are perpendicular to the bottom side 111.

[0064] In some embodiments, the body 10 further includes a stopper 14 disposed on the bottom plate 11, and the stopper 14 is used to stop at least one of the shifter 301 and the maintenance lamp 20. By the stopper 14 on the shifter 301 and / or the maintenance lamp 20, the maintenance lamp 20 is limited to a parking position closest to the room and the ground, that is, when the stopper 14 stops the shifter 301 and / or the maintenance lamp 20, the maintenance lamp 20 is fixedly parked relative to the body 10 and is closest to the room and the ground. The stopper 14 can be integrally formed with the bottom plate 11, or can be separately formed and fixedly connected with the bottom plate 11.

[0065] See also Figure 2 In some embodiments, the fuselage 10 includes a first chassis 101 and a second chassis 102 which are stacked and assembled as one, the air dispatching unit 40 is installed in the first chassis 101, and the second chassis 102 includes a bottom plate 11 and a mounting side 13 which are arranged opposite to each other and spaced apart, the bottom plate 11 is located on a side of the second chassis 102 which is relatively far away from the first chassis 101, the mounting side 13 is adjacent to a stacked side wall 1011 of the first chassis 101, and a displacement space 12 is formed by the interval between the bottom plate 11 and the mounting side 13, the displacement space 12 passes through the mounting side 13 to form an inlet 131, an inner side wall 121 of the displacement space 12 is formed in the second chassis 102, and a bottom wall of the displacement space 12 is formed in the stacked side wall 1011.

[0066] When the fuselage 10 is arranged in place in the ceiling space, the first chassis 101 and the second chassis 102 are stacked in the vertical direction, the stacked side wall 1011, the installation side 13, and the bottom plate 11 are sequentially arranged in the direction vertically close to the ground, and the inlet 131 and the light outlet 112 are sequentially arranged in the direction vertically close to the ground. When assembling the ceiling appliance 100 with maintenance function, first connect the driving component 30 and the second chassis 102, put the maintenance lamp 20 from the inlet 131 into the displacement space 12 and connect the shifter 301, so that the driving component 30, the maintenance lamp 20 and the second chassis 102 are assembled into one, install the air dispatching unit 40 on the first chassis 101, and finally stack the second chassis 102 on the side of the first chassis 101 close to the room.

[0067] Such an arrangement takes into account both the stopping of the maintenance lamp 20 by the limit part 14 and the convenience of assembly of the whole machine, thereby realizing the integration of the maintenance lamp 20 into the chassis. The maintenance lamp 20 is not easy to separate from the body 10, and there is no need to install the maintenance lamp 20 on the panel like existing similar products. Therefore, the maintenance lamp 20, the air dispatching unit 40 and the body 10 can be arranged in place at one time, reducing the steps and time consumption for indoor installation of the ceiling appliance 100 with maintenance function.

[0068] It can be understood that in other embodiments, the first chassis 101 and the second chassis 102 do not have to be stacked in the vertical direction, and can also be arranged in sequence in the horizontal direction and assembled into one. With such a configuration, the size of the second chassis 102 in the vertical direction can be equal to the size of the body 10 in the vertical direction, and thus the size of the displacement space 12 in the vertical direction can be designed to be larger, so that the maintenance lamp 20 can move relative to the body 10 within a longer moving stroke, thereby greatly changing the shape and irradiation range of the maintenance light beam.

[0069] See also Figure 3 to Figure 5 In some embodiments, the body 10 is further provided with a conveying passage 15 connected to the outside of the body 10, and the maintenance lamp 20 divides the displacement space 12 into two sub-areas, the first sub-area is located on the side of the maintenance lamp 20 relatively close to the room and the ground and is connected to the light outlet 112, and the second sub-area is located on the side of the maintenance lamp 20 relatively far from the room, that is, between the backlight portion 202 and the bottom wall of the displacement space 12, the air inlet end 411 of the wind drive member is connected to the second sub-area, and the second sub-area is connected to the conveying passage 15 to form a heat dissipation space.

[0070] Such an arrangement can prevent the maintenance lamp 20 from overheating and reducing the service life and performance of the light-emitting body 21, as well as avoid the heat accumulation of the maintenance lamp 20 from damaging the fuselage 10 and some important functional components inside the fuselage 10. The heat generated by the maintenance lamp 20 when it emits light is temporarily retained in the heat dissipation space. When the wind drive component is driven, the wind drive component can generate negative pressure in the fuselage 10. The air outside the fuselage 10 will enter the heat dissipation space through the conveying channel 15, and undergo convective heat exchange with the maintenance lamp 20 to reduce the heat of the maintenance lamp 20, and can drive the accumulated heat in the heat dissipation space into the wind drive component. Finally, the heat flows into the room with the airflow in the air duct 42.

[0071] Obviously, such an arrangement also realizes the secondary utilization of the heat of the maintenance lamp 20. When the air dispatching unit 40 blows hot air or warm air into the room, the heat in the heat dissipation space enters the air duct 42, thereby reducing the power of the heating device. Even when the air dispatching unit 40 blows warm air into the room, the heating device may not operate, and only the heat in the heat dissipation space is needed to heat the airflow in the air duct 42 to the required temperature.

[0072] See also Figure 1 , Figure 3 to Figure 5 The maintenance lamp 20 further includes a heat sink 50, which is used to increase the surface area of ​​the maintenance lamp 20, thereby accelerating the rate at which the maintenance lamp 20 dissipates heat. In some embodiments, the heat sink 50 includes heat sink fins 51, which are thermally connected to the lamp board 22.

[0073] Optionally, the heat dissipation fins 51 are connected to the backlight portion 202, specifically to the side of the light board 22 facing away from the light-emitting body 21. The side of the light board 22 facing away from the light-emitting body 21 is used to form an inner wall of the heat dissipation space. Therefore, the heat dissipation fins 51 are located in the heat dissipation space, and the airflow entering the heat dissipation space undergoes convection heat exchange with the heat dissipation fins 51.

[0074] In some embodiments, the ceiling appliance 100 with a maintenance function also includes a reflective wall, which is arranged on the periphery 221 of the maintenance lamp 20, and the reflective wall extends to a position protruding from the light-emitting portion 201. The portion of the reflective wall protruding from the light-emitting portion 201 can reflect a portion of the maintenance light outward from the light outlet 112, and the maintenance light irradiated on the reflective wall can also form a maintenance light beam directed toward the room and human skin.

[0075] See also Figure 1 , Figure 3-4In some embodiments, the inner wall 121 of the displacement space 12 forms at least a portion of a reflective wall, which can be obtained by grinding the inner wall 121 to reduce the roughness, or by attaching a reflective film with a lower roughness to the inner wall 121. When the output member 32 leaves the second extreme position and the maintenance lamp 20 leaves the parking position closest to the ground, the inner wall 121 protrudes from the light-emitting portion 201 in a direction close to the room and the ground, and part of the maintenance light is reflected by the inner wall 121 protruding from the light-emitting portion 201.

[0076] In this way, the proportion of maintenance light used to form the maintenance light beam is increased, so that the energy generated by the maintenance lamp 20 can be more fully and efficiently utilized, reducing power consumption and energy waste. The maintenance light beam refers to the maintenance light that finally exits the light outlet 112 and propagates into the room;

[0077] In addition, when the vertical height of the maintenance lamp 20 is constant, compared with the inner wall 121 without reflection ability, the inner wall 121 that can reflect the maintenance light and form a reflection wall does not cause the shape and irradiation range of the maintenance light beam to change. Figure 3-4 :

[0078] Figure 3 In the state shown, the inner wall 121 includes a first reflecting wall and a second reflecting wall that are opposite to each other and spaced apart, the displacement space 12 is located between the first reflecting wall and the second reflecting wall, and the irradiation range formed by the light directly emitted from the light outlet 112 of the light emitting unit 201 and not reflected by the first reflecting wall and the second reflecting wall is within Figure 3 In the figure, the angle α is shown, α=43°, and the light reflected by the first reflecting wall and the second reflecting wall is within the range of the angle α;

[0079] Figure 4 In the state shown, the irradiation range formed by the light directly emitted from the light emitting portion 201 to the light outlet 112 and not reflected by the first reflecting wall and the second reflecting wall is Figure 4 It is shown by angle β, β=85°. Similarly, the light reflected by the first reflecting wall and the second reflecting wall are all within the range of angle β.

[0080] Therefore, the shape and irradiation range of the maintenance light beam are related to the position of the reflective wall, and the opening shape and size of the light outlet 112. When the inner wall 121 forms a reflective wall and reflects the maintenance light into the room, it will not affect the shape and irradiation range of the maintenance light beam, but it can increase the energy of the maintenance light beam. It can be determined that setting the inner wall 121 as a reflective wall can increase the energy density of the central part of the maintenance light beam.

[0081] See also Figure 5-6In some embodiments, the reflective wall also includes a reflector 16 movably provided on the body 10, the reflector 16 is located at the periphery 221 of the maintenance lamp 20, and the reflector 16 extends to a position protruding from the light-emitting portion 201, and the portion of the reflector 16 protruding from the light-emitting portion 201 can reflect a portion of the maintenance light outward from the light outlet 112, so that the maintenance light irradiated on the reflector 16 can also form a maintenance light beam directed toward the room and human skin.

[0082] Figure 5 In the illustrated embodiment, the reflector 16 at least includes a first reflector 16 and a second reflector 16 which are spaced apart from each other, the space between the two reflectors 16 is connected to the light outlet 112, and the maintenance light 20 is located between the two reflectors 16. In this embodiment, the shape and irradiation range of the maintenance light beam are constrained and determined by the posture state, distance and shape and size of the two reflectors 16. Each reflector 16 can move relative to the fuselage 10, so as to reflect the maintenance light irradiated to itself in different directions in different posture states, thereby Figure 5 The illustrated embodiment allows the position of the reflector 16 relative to the body 10 to be adjusted to change the shape and irradiation range of the maintenance light beam.

[0083] Specifically, Figure 5 In the illustrated embodiment, the reflector 16 is movably connected to the shifter 301. The shifter 301 can drive the maintenance lamp 20 to move up and down in the displacement space 12, and can also drive the reflector 16 to move relative to the fuselage 10 to change the posture of the reflector 16, so that when the maintenance lamp 20 is at different vertical heights, the reflector 16 can reflect the maintenance light into the room in different postures and reflection directions.

[0084] See also Figure 5 and Figure 6 The first reflector 16 forms a first reflective surface on one side relatively close to the second reflector 16, and the second reflector 16 forms a second reflective surface on one side relatively close to the first reflector 16. The light-emitting portion 201 is located between the first reflective surface and the second reflective surface. Both the first reflective surface and the second reflective surface protrude from the reflective portion, and the two are used to receive the curing light and reflect the curing light out of the light outlet 112.

[0085] The first reflector 16 and the second reflector 16 have the same structure. Taking one of them as an example, the reflector 16 includes a first end 161 and a second end 162. The first end 161 is an end of the reflector 16 that is relatively far from the room and the ground, and the second end 162 is an end of the reflector 16 that is relatively close to the room and the ground. The first end 161 is rotatably connected to the output member 32 and / or the maintenance lamp 20, and can rotate relative to the output member 32, the body 10 and the maintenance lamp 20. The second end 162 is rotatably and movably connected to the body 10. The direction in which the first end 161 moves relative to the body 10 is different from the direction in which the second end 162 moves relative to the body 10.

[0086] Optionally, the first end 161 can follow the output member 32 and the maintenance lamp 20 to move perpendicularly to the bottom side 111 along a preset moving trajectory, and the second end 162 can move in a direction parallel to the bottom side 111 .

[0087] Optionally, the first end 161 is hinged or pivoted to the output member 32 and / or the lamp panel 22 of the maintenance lamp 20, and the second end 162 and one of the fuselage 10 are provided with a slide groove, and the other is provided with a slider slidably arranged in the slide groove, and the slider can also rotate relative to the slide groove, and the extension direction of the slide groove is not parallel to the preset moving trajectory.

[0088] The reflective surface of the reflector 16 faces the room and is tilted relative to the bottom side 111 and the vertical direction. As the shifter 301 drives the maintenance lamp 20 and the reflector 16 to move, the tilt direction of the reflective surface 163 changes synchronously. The following describes the influence of the posture state and tilt direction of the reflective surface 163 on the shape and irradiation range of the maintenance light beam:

[0089] See also Figure 5-6 When the shifter 301 drives the maintenance lamp 20 to move upward away from the room, the first end 161 of the first reflector 16 and the first end 161 of the second reflector 16 rise with the maintenance lamp 20, and the second end 162 of the first reflector 16 moves relative to the fuselage 10 in a direction close to the second reflector 16, and the second end 162 of the second reflector 16 moves relative to the fuselage 10 in a direction close to the first reflector 16, that is, the distance between the second ends 162 of the two reflectors 16 becomes smaller, and at this time, the shape of the first reflecting surface of the first reflector 16 projected on the horizontal plane becomes smaller, and the shape of the second reflecting surface of the second reflector 16 projected on the horizontal plane also becomes smaller, and the shape of the maintenance light beam tends to change from a cone to a cylinder, and the irradiation range gradually becomes smaller;

[0090] When the shifter 301 drives the maintenance lamp 20 to move downward toward the room, the first end 161 of the first reflector 16 and the first end 161 of the second reflector 16 descend with the maintenance lamp 20, the second end 162 of the first reflector 16 moves relative to the fuselage 10 in a direction away from the second reflector 16, and the second end 162 of the second reflector 16 moves relative to the fuselage 10 in a direction away from the first reflector 16, that is, the distance between the second ends 162 of the two reflectors 16 increases. At this time, the shape of the first reflecting surface of the first reflector 16 projected on the horizontal plane increases, and the shape of the second reflecting surface of the second reflector 16 projected on the horizontal plane increases. The shape of the maintenance light beam tends to change from a column to a cone, and the irradiation range increases.

[0091] It is worth noting that when the maintenance lamp 20 includes a light-expanding reflective wall 231, the shape and structure of the light-expanding reflective wall 231 should ensure that the maintenance light of the light-emitting body 21 is reflected by the light-expanding reflective wall 231 to form a beam that is approximately columnar or conical. Specifically, the maintenance light beam is cut by any two parallel planes, and the two planes are arranged in sequence along a direction perpendicular to the bottom side 111. The maintenance light beam is cut by a plane relatively far from the ground and recorded as a first beam section. The maintenance light beam is cut by a plane relatively close to the ground and recorded as a second beam section. It is required that the area of ​​the first beam section is smaller than the area of ​​the second beam section. If the area of ​​the first beam section is greater than or equal to the area of ​​the second beam section, the shape and irradiation range of the maintenance light beam may not change regardless of whether the output member 32 moves to the first extreme position or the second extreme position.
