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] Ceiling appliances include bathroom heaters, ventilation fans, fresh air blowers, etc. They are a type of electrical equipment that can deliver airflow to the room. The delivered airflow can be warm air or outdoor fresh air. Taking bathroom heaters as an example, existing bathroom heaters also include maintenance lights installed on the body panel. Existing ceiling appliances equipped with maintenance lights mostly adopt the design of fixedly installing the maintenance lights on the body panel, so as to facilitate the design of heat dissipation devices for the maintenance lights, such as heat dissipation fans. In order to meet the user's demand for adjustable position and posture of the maintenance light to achieve the adjustable range and direction of the maintenance light, it is necessary to change the maintenance light to a movable design relative to the body, which brings difficulties to the heat dissipation of the maintenance light. Utility Model Content

[0003] In view of this, the utility model provides a ceiling appliance with a maintenance function which allows a maintenance lamp to change its position to achieve an adjustable maintenance light effect and can dissipate heat and cool the maintenance lamp.

[0004] The utility model provides a ceiling-mounted appliance with a maintenance function, which comprises a body, a maintenance lamp and an air adjustment device. The body is provided with a heat dissipation air inlet connected to the outside of the body, and has a storage cavity connected to the heat dissipation air inlet; the maintenance lamp can be movably arranged in the storage cavity and can move closer to and away from the room; the air adjustment device comprises an air inlet end connected to the storage cavity, and can absorb air in the storage cavity through the air inlet end; the air pressure of at least part of the storage cavity drops after the air adjustment device is started, so that air is injected into the storage cavity from the heat dissipation air inlet.

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

[0006] The maintenance lamp can move closer to and farther from the room in the storage cavity to change the distance between the light-emitting part of the maintenance lamp and the user and obtain the effect of adjustable maintenance light irradiation range;

[0007] On the other hand, the storage cavity draws in air from outside the fuselage after the air dispatching device is started. The air undergoes convective heat exchange with the surface of the maintenance lamp to dissipate heat from the maintenance lamp, eventually forming heat-absorbing air and being sucked in by the air inlet end. While the user is using the maintenance lamp for maintenance and beauty, he can also be blown by the heat-absorbing air. Especially when the air dispatching device operates in warm air mode to heat or keep the room warm, the heat-absorbing air can be used as part of the warm air to reduce the energy consumption required to heat the air.

[0008] In one embodiment, the maintenance lamp includes a heat storage portion located in the storage cavity, and at least a portion of the heat storage portion is located on a side of the maintenance lamp relatively close to the air inlet end.

[0009] With such arrangement, when the air inlet end draws air, the airflow about to enter the air inlet end undergoes convective heat exchange with the heat storage part, and the airflow can more efficiently take away the heat of the heat storage part.

[0010] In one embodiment, the heat storage portion is disposed opposite to the air inlet end and spaced apart from each other.

[0011] With such arrangement, the interval between the heat storage portion and the air inlet end can reduce the resistance when the air inlet end absorbs air.

[0012] In one embodiment, the air dispatching device includes a centrifugal fan, and the centrifugal fan includes an air inlet end, and the projection of the air inlet end onto the heat storage portion is entirely located in the heat storage portion.

[0013] Such an arrangement can increase the proportion of air that undergoes convective heat transfer with the heat storage part among all the air entering the air inlet end, thereby helping to improve the heat dissipation rate of the heat storage part.

[0014] In one embodiment, the air dispatching device includes a centrifugal fan, the centrifugal fan includes an air inlet end, the maintenance lamp includes a lamp board, a heat storage part is formed on one side of the lamp board, and the wind wheel axis of the centrifugal fan is perpendicular to the heat storage part.

[0015] In this way, if the air entering the air inlet end and undergoing convective heat transfer with the surface of the heat storage part is defined as heat-absorbing air, the flow velocity and flow rate of the heat-absorbing air entering the air inlet end along each radial direction of the air inlet end are relatively uniform, thereby improving the uniformity of heat absorption at each position of the heat storage part.

[0016] In one embodiment, the air dispatching device includes a centrifugal fan, the centrifugal fan includes an air inlet end, the maintenance lamp includes a lamp board, one side of the lamp board forms a heat storage portion, and the maintenance lamp is movably arranged relative to the fuselage along a preset lifting trajectory, and the preset lifting trajectory is parallel to the wind wheel axis of the centrifugal fan.

[0017] With such arrangement, the flow resistance of the heat-absorbing air entering the air inlet end along each radial direction of the air inlet end is relatively uniform, and the uniformity of the flow resistance of the heat-absorbing air in each radial direction of the air inlet end will not change significantly as the maintenance lamp is raised and lowered relative to the fuselage. That is, even if the maintenance lamp is at different heights, it can ensure that the flow resistance of the heat-absorbing air entering the air inlet end along each radial direction of the air inlet end is uniform.

[0018] In one embodiment, the maintenance lamp is further provided with a heat sink thermally connected to the heat storage portion, and the heat sink has a heat dissipation surface protruding from the heat storage portion.

[0019] With such an arrangement, the heat sink can provide a larger heat dissipation surface for contacting the air in the storage cavity, which helps to improve the heat dissipation rate of the maintenance lamp.

[0020] In one embodiment, the storage cavity passes through the side of the body facing the indoor room and forms a light outlet for the light emitting part of the maintenance lamp to emit maintenance light into the indoor room.

[0021] With such arrangement, even if the maintenance lamp remains stored in the storage cavity, the maintenance lamp can still emit maintenance light into the room, so the maintenance lamp can emit light and dissipate heat at the same time.

[0022] In one embodiment, the air regulation device is arranged on a side of the maintenance lamp away from the light outlet and the indoor room.

[0023] With such arrangement, the air regulation device will not affect the maintenance lamp emitting maintenance light, nor will it affect the emission of maintenance light from the light outlet into the room, and the air regulation device is located on the side of the maintenance lamp away from the light-emitting part, so that air can flow through the backlight of the maintenance lamp after startup, so that the backlight part with more serious heat accumulation can be adequately dissipated and cooled.

[0024] In one embodiment, the maintenance lamp is slidably connected to the inner wall surface of the storage cavity, and the storage cavity includes a heat collection cavity located between the maintenance lamp and the air inlet end and connected to the heat dissipation air inlet.

[0025] Such an arrangement can maintain the heat collection chamber relatively closed to a certain extent, and can prevent the air outside the fuselage from flowing directly into the air inlet end after passing between the maintenance lamp and the inner wall of the storage chamber, thereby preventing the air entering the air inlet end from failing to fully undergo convective heat transfer with the maintenance lamp. This is beneficial for the air entering the air inlet end to undergo convective heat transfer with the surface of the maintenance lamp as much as possible to increase the amount of heat absorbed.

[0026] In one embodiment, the inner wall of the storage cavity includes an inner side wall slidably connected to the maintenance lamp, and the heat dissipation air inlet passes through the inner side wall to communicate with the storage cavity.

[0027] With such arrangement, the air flowing out from the heat dissipation air inlet and flowing into the storage cavity has a velocity direction that is more suitable for convective heat transfer with the maintenance lamp. This part of the air will not change its flow direction or attenuate its flow rate due to hitting the surface of the maintenance lamp. That is, this part of the air can flow through the surface of the maintenance lamp with less kinetic energy loss, thereby dissipating the heat of the maintenance lamp more efficiently.

[0028] In one embodiment, it also includes an output member arranged on the maintenance lamp, and a driving member arranged on the body and connected to the output member, and the output member is movably arranged relative to the body along the depth direction of the storage cavity.

[0029] In this way, the ceiling appliance with maintenance function can provide power through the driving part and transmit the power to the maintenance lamp through the output part, so as to automatically realize the movement of the maintenance lamp relative to the body in the storage cavity to change the irradiation range and / or irradiation direction of the maintenance light, which can be completed without manual force.

[0030] In one embodiment, the air dispatching device includes an air duct, both ends of which pass through the outside of the fuselage and form an air inlet and an air outlet respectively, and the heat dissipation air inlet is connected to the air inlet.

[0031] With this arrangement, the air entering the air inlet from outside the fuselage is divided into two parts. One part of the air flows directly into the air duct, and the other part of the air flows through the heat dissipation air inlet, the storage cavity, the air inlet end and the air duct in sequence, thereby ensuring the air requirements of the air scheduling function and the air cooling function.

[0032] In one embodiment, the fuselage includes a first chassis and a second chassis stacked together, the air distribution device is disposed in the first chassis, the second chassis is provided with a heat dissipation air inlet and a storage cavity, the storage cavity passes through a side of the second chassis away from the first chassis to form a light outlet for a maintenance lamp to emit maintenance light.

[0033] With this arrangement, the assembly of the ceiling appliance with maintenance function is simpler. The air dispatching device can be installed in the first chassis and the maintenance lamp can be installed in the second chassis separately, and finally the first chassis and the second chassis can be combined and installed.

[0034] In one embodiment, the fuselage includes a first chassis and a second chassis stacked together, the air dispatching device is arranged in the first chassis, the second chassis is provided with a heat dissipation air inlet and a storage cavity, the storage cavity runs through the side of the second chassis close to the first chassis so that the air inlet end is connected to the storage cavity.

[0035] With such an arrangement, it is easier to establish a connection between the air inlet end and the storage chamber. When the first chassis is equipped with an air dispatching device and the second chassis is equipped with a maintenance lamp, the air inlet end can be connected to the storage chamber by simply assembling the first chassis and the second chassis.

DETAILED DESCRIPTION

[0043] 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.

[0044] 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.

[0045] 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 used to generate maintenance light and radiate energy to human skin for skin maintenance therapy, thereby achieving beauty maintenance effects.

[0046] The utility model provides a ceiling appliance 100 with a maintenance function, comprising a body 10, a maintenance lamp 20 movably arranged relative to the body 10, and an air adjustment device 40 mounted on the body 10. The ceiling appliance 100 with a maintenance function has both a beauty maintenance function and an air adjustment function, and can be used in a bathroom or other indoor places. When the ceiling appliance 100 with a maintenance function is a heater installed in a bathroom, the body 10 can be arranged in the ceiling space between the bathroom ceiling and the ceiling board.

[0047] In some embodiments, the ceiling appliance 100 with a maintenance function further includes a driving component 30, which is connected to the maintenance lamp 20 and is used to drive the maintenance lamp 20 to move relative to the body 10. In other embodiments, the ceiling appliance 100 with a maintenance function does not include the driving component 30, and manual force is applied to drive the maintenance lamp 20 to move relative to the body 10.

[0048] It is understandable that when the ceiling appliance 100 with maintenance function is installed and used in other indoor places, the ceiling appliance 100 with maintenance function can also be suspended relative to the ground in other ways, without being limited to arranging the body 10 between the ceiling and the ceiling panel.

[0049] The ceiling appliance 100 with maintenance function of the present invention can be a heater equipped with maintenance lamp 20, or a ventilation fan equipped with maintenance lamp 20, or a fresh air blower equipped with maintenance lamp 20. The present invention is described below by taking a heater equipped with maintenance lamp 20 as an example.

[0050] The body 10 can be arranged on a ceiling plate, and the body 10 includes a bottom side 111 facing the room when the body 10 is arranged on the ceiling plate. Figure 1 , Figure 3-4 The body 10 includes a bottom plate 11, which is located on a side of the body 10 close to the room to form the bottom of the body 10, and the bottom side 111 includes a side of the bottom plate 11 facing the room. The body 10 is provided with a storage cavity 12 and a heat dissipation air inlet 15. The body 10 accommodates the maintenance lamp 20 through the storage cavity 12, and the heat dissipation air inlet 15 connects the storage cavity 12 with the outside of the body 10, so that the air outside the body 10 can enter the storage cavity 12 through the heat dissipation air inlet 15.

[0051] The maintenance lamp 20 is movably disposed in the storage cavity 12, and can be moved closer to or farther from the room under the drive of the driving assembly 30 or manual operation. The maintenance lamp 20 includes a light-emitting portion 201 for emitting maintenance light to radiate energy to human skin, and also includes a heat-storage portion that is always located in the storage cavity 12, and the surface temperature of the heat-storage portion increases as the light-emitting portion 201 emits maintenance light. After the body 10 is arranged in place on the ceiling board, the maintenance lamp 20 can move closer to the room and the ground to reduce the distance from the light-emitting portion 201 to the user, and can move away from the room and the ground to increase the distance from the light-emitting portion 201 to the user.

[0052] Specifically, the receiving cavity 12 penetrates the bottom side 111 of the body 10 to form a light outlet 112, see Figure 1 , Figure 3-4 Optionally, the bottom plate 11 is provided with a light outlet 112, which passes through the side of the bottom plate 11 facing the room and the side away from the room, and the storage cavity 12 is formed on the side of the bottom plate 11 away from the room. The light emitting portion 201 faces the room through the light outlet 112, and emits the maintenance light into the room through the light outlet 112. The distance between the light emitting portion 201 and the bottom side 111 decreases as the maintenance lamp 20 moves closer to the room and the ground, and increases as the maintenance lamp 20 moves away from the room and the ground.

[0053] See also Figure 1-2 In some embodiments, the maintenance lamp 20 includes a lamp board 22 and a light emitter 21. The light emitter 21 may be one or more. The multiple light emitters 21 may be arranged in a row, array, or randomly dispersed on one side of the lamp board 22. The light emitting portion 201 includes the light emitter 21 and the side of the lamp board 22 on which the light emitter 21 is disposed. The maintenance lamp 20 also includes a backlight portion 202 disposed opposite to the light emitting portion 201. The backlight portion 202 includes a side of the lamp board 22 away from the light emitter 21. The backlight portion 202 serves as a heat storage portion of the maintenance lamp 20. The surface temperature of the backlight portion 202 increases when the light emitter 21 emits maintenance light.

[0054] When the fuselage 10 is arranged in place on the ceiling board, the distance between the maintenance lamp 20 and the ground is Figure 3 In the state shown, the distance between the light emitting part 201 and the user is the largest, and the distance between the maintenance lamp 20 and the ground is Figure 4 It reaches the minimum in the state shown, that is, at this time the distance between the light-emitting part 201 and the user is the smallest, the light-emitting part 201 is always facing the ground, and as the maintenance lamp 20 rises and falls, the irradiation range of the maintenance light emitted from the light-emitting part 201 changes, and the light spot formed after the maintenance light hits the ground decreases and the brightness increases as the maintenance lamp 20 approaches the ground, and expands and the brightness decreases as the maintenance lamp 20 moves away from the ground. The backlight part 202 is always in the storage cavity 12 and away from the ground.

[0055] The air dispatching device 40 includes an air inlet end 411 connected to the storage chamber 12. After the air dispatching device 40 is started, the air in the storage chamber 12 is sucked through the air inlet end 411, so that the air pressure of at least a part of the storage chamber 12 decreases after the air dispatching device 40 is started, thereby generating a pressure difference between the storage chamber 12 and the outside of the fuselage 10. Under the action of the pressure difference, the air outside the fuselage 10 enters the storage chamber 12 through the heat dissipation air inlet 15, and at least a part of the air undergoes convective heat transfer with the surface of the heat storage part. When the air dispatching device 40 continues to operate, the air outside the fuselage 10 continuously enters the storage chamber 12 to dissipate heat from the heat storage part.

[0056] Specifically, see Figure 1 , Figure 3-4 The air dispatching device 40 is arranged on the side of the maintenance lamp 20 away from the light outlet 112, the room and the ground, and includes a centrifugal fan 41 and an air duct 42 surrounding the centrifugal fan 41. One end of the centrifugal fan 41 forms an air inlet end 411 and is connected to the storage chamber 12. The backlight part 202 is located on the side of the lamp board 22 relatively close to the air inlet end 411 of the centrifugal fan 41 and forms a heat storage part. After the centrifugal fan 41 is started, the air outside the fuselage 10 passes through the heat dissipation air inlet 15-storage chamber 12-air inlet end 411 in sequence, and finally flows into the air duct 42 to form an airflow.

[0057] See also Figure 3 The backlight 202 and the air inlet end 411 are arranged opposite to each other. Even if the distance from the maintenance lamp 20 to the ground is minimized, there is still a gap between the backlight 202 and the air inlet end 411, which does not affect the convection heat transfer between the air on the side of the lamp board 22 close to the air inlet end 411 and the backlight 202, nor does it affect the air on the side of the lamp board 22 close to the air inlet end 411 absorbing the heat of the backlight 202 and then being sucked into the centrifugal fan 41 through the air inlet end 411.

[0058] When the ceiling appliance 100 with maintenance function is a heater equipped with a maintenance lamp 20, the downstream end of the air duct 42 passes through the bottom side 111 or other positions on the body 10 facing the room to form an air outlet, and finally the airflow in the air duct 42 is blown into the room through the air outlet. These airflows can be normal temperature airflows with a temperature close to the room temperature, or warm airflows with a temperature higher than the room temperature. In order to obtain warm airflows, a heating device for heating the airflow can also be arranged at the centrifugal fan 41, the air duct 42 or the air outlet.

[0059] Obviously, the air that undergoes convective heat transfer with the heat storage part in the storage cavity 12 will absorb the heat of the maintenance lamp 20 and thus heat up. After these airflows enter the air duct 42, they can flow out of the air outlet as part of the warm airflow. Therefore, the power consumption required for the heating device to heat the airflow to obtain the warm airflow can be reduced to a certain extent. When the temperature of the warm airflow is low, the heating device can even be stopped. At this time, the warm airflow all comes from the air that absorbs the heat of the maintenance lamp 20 in the storage cavity 12.

[0060] Optionally, in some embodiments, the maintenance lamp 20 is also equipped with a heat sink 50, see Figure 1-2 , Figure 3-4 The heat sink 50 is thermally connected to the heat storage part and is always located in the storage cavity 12. Specifically, the heat sink 50 includes heat dissipation fins 51 protruding from the backlight part 202. The heat dissipation fins 51 provide a heat dissipation surface protruding from the surface of the heat storage part, that is, protruding from the surface of the backlight part 202. It can be understood that the heat sink 50 is not limited to the heat dissipation fins 51, and can also be a heat dissipation column protruding from the backlight part 202.

[0061] Optionally, in some embodiments, a sliding connection is formed between the maintenance lamp 20 and the inner wall surface of the storage chamber 12, and the maintenance lamp 20 divides the storage chamber 12 into at least two parts, one of which is located between the maintenance lamp 20 and the air inlet end 411, and this part is connected to the heat dissipation air inlet 15 to form a heat collection chamber 122. Figure 3 Figure 4 A sliding fitting contact is formed between the peripheral edge 221 of the lamp panel 22 and the inner side wall 121 of the storage cavity 12 . The storage cavity 12 includes a heat collecting cavity 122 located between the backlight portion 202 and the air inlet end 411 . The heat collecting cavity 122 is always connected to the heat dissipation air inlet 15 .

[0062] The heat collection chamber 122 is a spatial area where the maintenance lamp 20 heats up significantly and accumulates heat during the process of emitting maintenance light. After the air dispatching device 40 is started, the air inside the heat collection chamber 122 will be first sucked into the air inlet end 411, so the air pressure inside the heat collection chamber 122 will first drop, and a pressure difference will be generated at both ends of the heat dissipation air inlet 15. Under the action of the pressure difference, the air outside the fuselage 10 is injected into the heat collection chamber 122 through the heat dissipation air inlet 15, and then the air that has just entered the heat collection chamber 122 and the backlight part 202 undergo convection heat transfer.

[0063] The sliding connection between the edge 221 of the lamp panel 22 and the inner side wall 121 improves and maintains the relative closedness of the heat collection chamber 122 to a certain extent, and does not affect the normal lifting and lowering movement of the maintenance lamp 20 relative to the fuselage 10. After the air dispatching device 40 is activated, it can prevent the air outside the fuselage 10 from flowing through the maintenance lamp 20 and the inner side wall 121 of the storage chamber 12 and directly flowing into the air inlet end 411, and prevent the air from failing to conduct convective heat transfer with the heat storage part and directly flowing into the air duct 42, so as to increase the proportion of air that conducts convective heat transfer with the heat storage part in the air entering the air inlet end 411.

[0064] Optionally, in some embodiments, the heat dissipation air inlet 15 passes through the inner wall 121 of the storage cavity 12 and is connected to the storage cavity 12. Figure 3-4 In the illustrated embodiment, the inner wall 121 is perpendicular or approximately perpendicular to the bottom side 111, the bottom side 111 is a plane, the direction in which the maintenance lamp 20 moves relative to the body 10 is perpendicular or approximately perpendicular to the bottom side 111, one end of the heat dissipation air inlet 15 passes through the bottom side 111, and the other end passes through the inner wall 121 to connect to the heat collection chamber 122. After the air dispatching device 40 is started, the indoor air is sucked into the heat dissipation air inlet 15 and then injected into the storage chamber 12.

[0065] Optionally, in some embodiments, the air dispatching device 40 includes a centrifugal fan 41, and one end of the centrifugal fan 41 that allows air to be inhaled forms an air inlet end 411, and the backlight portion 202 forms the heat storage portion of the maintenance lamp 20, and the projection of the air inlet end 411 on the heat storage portion is entirely located in the heat storage portion. This arrangement can increase the proportion of air that undergoes convective heat transfer with the heat storage portion and absorbs heat in all the air entering the air inlet end, which helps to improve the heat dissipation efficiency of the heat storage portion.

[0066] Optionally, in some embodiments, the air dispatching device 40 includes a centrifugal fan 41, one end of the centrifugal fan 41 that allows air to be inhaled forms an air inlet 411, the backlight portion 202 forms a heat storage portion of the maintenance lamp 20, and the wind wheel axis of the centrifugal fan 41 is perpendicular to the heat storage portion. The wind wheel axis is the rotation center of the centrifugal wind wheel of the centrifugal fan 41 and is also the axis of the centrifugal wind wheel. If the air that enters the air inlet 411 and undergoes convective heat transfer with the heat storage portion is defined as heat absorbing air, the flow rate and flow rate of the heat absorbing air that enters the air inlet 411 along each radial direction of the air inlet 411 are relatively uniform.

[0067] Optionally, in some embodiments, the air dispatching device 40 includes a centrifugal fan 41, one end of the centrifugal fan 41 that allows air to be sucked in forms an air inlet end 411, the backlight portion 202 forms a heat storage portion of the maintenance lamp 20, and the maintenance lamp 20 is movably arranged relative to the fuselage 10 along a preset lifting trajectory, and the preset lifting trajectory is parallel to the wind wheel axis of the centrifugal fan 41. With such an arrangement, the flow resistance of the heat-absorbing air entering the air inlet end 411 along each radial direction of the air inlet end 411 is relatively uniform.

[0068] In some embodiments, the driving assembly 30 includes a shifter 301, which includes an output member 32 provided on the maintenance lamp 20 and a driving member 31 provided on the body 10 and connected to the output member 32. The output member 32 is movably arranged relative to the body 10 along the depth direction of the storage cavity 12. The driving member 31 is used to generate power to move the maintenance lamp 20 closer to and away from indoor activities. The output member 32 drives the maintenance lamp 20 to move up and down in the storage cavity 12 under the drive of the driving member 31.

[0069] Optionally, the output member 32 and the maintenance lamp 20 are relatively fixed, and the two can move synchronously along the depth direction of the storage cavity 12 under the drive of the driving member 31. The depth direction of the storage cavity 12 is the extension direction of the preset lifting trajectory mentioned above. This direction can be a straight line direction forming a 90° angle with the bottom side 111, or it can be a straight line direction forming an angle of approximately 90° with the bottom side 111.

[0070] Optional, see Figure 1 , Figure 3-4 In some embodiments, the output member 32 includes a rack 321 that is movably disposed relative to the body 10, the driving member 31 includes a gear 311 meshing with the rack 321, and the lamp board 22 is connected to the rack 321. After the driving member 31 is started, the gear 311 rotates and drives the rack 321 to move relative to the body 10, so that the maintenance lamp 20 moves relative to the body 10 following the rack 321. The extension direction of the above-mentioned preset lifting trajectory is the same as the length direction of the rack 321, and the same as the moving direction of the rack 321. Preferably, the rack 321 forms a sliding fit with the inner side wall 121 of the storage cavity 12.

[0071] It is understandable that in other embodiments, the gear 311 and the rack 321 may be replaced by other types of drive components.

[0072] In some embodiments, the upstream end of the air duct 42 passes through the fuselage 10 to form an air inlet connected to the outside of the fuselage 10, and the heat dissipation air inlet 15 is connected to the air inlet. Optionally, the upstream end of the air duct 42 passes through the bottom side 111 to communicate with the indoor space. Of course, the upstream end of the air duct 42 can also be connected to the outdoors. When the air duct 42 is connected to the indoor space, the air dispatching device 40 is responsible for circulating the air between the indoor space and the air dispatching device 40 to repeatedly output normal temperature airflow or warm airflow to the indoor space; when the air duct 42 is connected to the outdoor space, the air dispatching device 40 is responsible for replenishing the outdoor air to the indoor space.

[0073] See also Figure 1 , Figure 3-4 In some embodiments, the fuselage 10 includes a first chassis 101 and a second chassis 102 that are stacked. When the fuselage 10 is arranged in place on the ceiling plate, the first chassis 101 and the second chassis 102 are stacked in a vertical direction. The air dispatching device 40 is mounted on the first chassis 101. The first chassis 101 includes a stacked side wall 1011 for being adjacent to the second chassis 102. The second chassis 102 includes an installation side 13 for being adjacent to the stacked side wall 1011. The installation side 13 is arranged opposite to the bottom side 111. The storage cavity 12 is opened in the second chassis 102 and passes through the installation side 13 and the bottom side 111. The stacked side wall 1011 is opened to expose the air inlet end 411 so as to connect to the storage cavity 12.

[0074] Optionally, the heat dissipation air inlet 15 is opened in the second chassis 102 .

[0075] Optionally, the bottom side 111 is provided with an air inlet and an air outlet connected to the air duct 42 .

[0076] Optionally, the air inlet and the air outlet connected to the air duct 42 may also be opened at other positions on the second chassis 102 , not limited to the bottom side 111 .

[0077] The storage cavity 12 penetrates the bottom side 111 to form a light outlet 112 for providing maintenance light to the indoor room. The storage cavity 12 penetrates the installation side 13 to form an entry port 131. When assembling the ceiling appliance 100 with maintenance function, the maintenance lamp 20 is loaded into the storage cavity 12 from the entry port 131. The body 10 also includes a limiting portion 14 arranged on the bottom side 111. The limiting portion 14 is used to stop the maintenance lamp 20 and / or the output member 32. When the maintenance lamp 20 and / or the output member 32 are stopped by the limiting portion 14, the height of the maintenance lamp 20 from the ground reaches the minimum.

[0078] Assembly Figure 1 , Figure 3-4The ceiling appliance 100 with maintenance function shown in the figure can be assembled simultaneously on two sub-assembly lines, one of which is responsible for installing the air adjustment device 40 into the first chassis 101, and obtaining the air adjustment assembly after assembly, and the other sub-assembly line is responsible for installing the maintenance lamp 20 and the drive component 30 into the second chassis 102, and obtaining the irradiation maintenance assembly after assembly, and finally the air adjustment assembly and the irradiation maintenance assembly are combined and assembled to obtain the ceiling appliance 100 with maintenance function.

[0079] In some embodiments, the fuselage 10 includes a storage cover 123 stacked with the base plate 11. When the fuselage 10 is arranged in place on the ceiling plate, the base plate 11 and the storage cover 123 are arranged in sequence along the vertical direction. The air dispatching device 40 is arranged on the side of the storage cover 123 away from the base plate 11. A storage cavity 12 is formed inside the storage cover 123. The inner surface of the storage cover 123 forms an inner side wall 121 of the storage cavity 12. An air vent for connecting the storage cavity 12 and the air inlet end 411 is provided on the side of the storage cover 123 close to the air dispatching device 40.

[0080] Specifically, see Figure 5 The heat dissipation air inlet 15 is provided on the bottom plate 11, and the storage cover 123 does not cover the heat dissipation air inlet 15. The heat dissipation air inlet 15 is also provided with a ventilation hole. After the air regulation device 40 is started, the air entering the heat dissipation air inlet 15 is divided into two parts. One part directly flows to the air inlet end 411 and is thus obtained by the centrifugal fan 41, and the other part first flows through the ventilation hole to enter the storage cover 123, and then conducts convection heat transfer with the heat storage part of the maintenance lamp 20, and then flows out of the storage cover 123 through the ventilation hole to enter the air inlet end 411. Preferably, the ventilation hole and the ventilation hole are both provided on the side of the storage cover 123 close to the air regulation device 40, and the backlight part 202 and the side of the storage cover 123 close to the air regulation device 40 are spaced and arranged opposite to each other. After the air enters the storage cover 123 through the ventilation hole, it will fully absorb the heat of the backlight part 202.

[0081] See also Figure 6 , different from Figure 5 In the illustrated embodiment, the heat dissipation air inlet 15 is opened on the bottom plate 11, and the storage cover 123 covers the heat dissipation air inlet 15. After the air dispatching device 40 is started, the air entering the heat dissipation air inlet 15 directly enters the storage cavity 12 in the storage cover 123. After absorbing the heat of the backlight 202, the air flows out of the storage cover 123 from the air holes in a concentrated manner, and is finally obtained by the centrifugal fan 41 from the air inlet end 411.
