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 the room or renew the indoor air, along with ventilation fans and fresh air blowers. Taking Yuba as an example, existing Yuba also includes maintenance lamps. Existing Yuba usually adopts the design of fixing the beauty lamp on the body panel. The maintenance lamp is exposed to the humid gas environment of the bathroom for a long time, which will lead to the reduction of the reliability and durability of the beauty lamp, and the performance and efficacy of the beauty lamp will be weakened. Utility Model Content

[0003] In view of this, the utility model provides a ceiling appliance with a maintenance function, which can overcome the defects of reduced reliability and durability due to exposure of the maintenance lamp in a humid environment, thereby improving or maintaining the performance and efficacy of the maintenance lamp.

[0004] The utility model provides a ceiling-mounted appliance with a maintenance function, comprising a body and a maintenance lamp. The body can be arranged on the ceiling board, and the maintenance lamp is movably arranged on the body and can move relative to the body to a working position and a parking position; when the maintenance lamp is in the working position, the light-emitting side of the maintenance lamp faces the room; when the maintenance lamp is in the parking position, at least part of the maintenance lamp is stored inside the body; and / or, at least part of the maintenance lamp is parked on a part of the body located on the far side of the ceiling board.

[0005] The beneficial effects of the present invention are that when the beauty and treatment function of a ceiling appliance with a maintenance function is not enabled, the maintenance lamp is switched to a parking position so that at least a part of the maintenance lamp is evacuated from the room and transferred to the inside of the machine body and / or the far side of the ceiling panel, thereby reducing the time the maintenance lamp is exposed to the indoor humid gas environment, thereby improving the reliability and durability of the maintenance lamp, reducing the risk of maintenance lamp failure, and helping to improve or maintain the performance and efficacy of the maintenance lamp.

[0006] In one embodiment, the fuselage includes a bottom plate for facing the room, and a storage space is provided inside the bottom plate on a side away from the room, and the maintenance lamp is moved out of the storage space when in the working position, and at least partially withdrawn into the storage space when in the parking position. In this way, the maintenance lamp can be better protected in the parking position, further reducing the contact between the maintenance lamp and water mist, dust and other substances outside the fuselage, thereby extending the service life of the maintenance lamp, so that the maintenance lamp maintains good performance and efficacy for a longer period of time.

[0007] In one embodiment, the maintenance lamp does not protrude from the side of the bottom plate facing the room when it is in the parking position. In this way, the maintenance lamp in the parking position will not affect the user under the bottom plate.

[0008] In one embodiment, the projections of the bottom plate and the maintenance lamp in the working position projected on the parallel plane of the ceiling plate do not overlap. In this way, the bottom plate will not block the maintenance lamp in the working position, so the maintenance light emitted by the maintenance lamp in the working position will not be blocked by the bottom plate.

[0009] In one embodiment, the side of the body facing the room is provided with an entrance and an exit, the entrance and an exit pass through both sides of the bottom plate to connect to the storage space, and the entrance and an exit are used for the maintenance lamp to be moved out of the storage space to switch to the working position. With such an arrangement, the maintenance lamp can switch between the working position and the docking position more efficiently and conveniently.

[0010] In one embodiment, the projection of the bottom plate on the parallel surface of the ceiling plate is the plate surface projection, and the projection of the maintenance lamp in the working position on the parallel surface of the ceiling plate is the light projection, and the light projection is located at the outer edge of the plate surface projection. This arrangement overcomes the defect of the maintenance lamp, the vents opened on the bottom plate and the functional parts arranged on the bottom plate in the existing similar products, which are closely packed with each other, so as to leave a larger area on the bottom plate for opening the vents and arranging other functional parts.

[0011] In one embodiment, the body further includes a case provided on the side of the bottom plate away from the room and having a storage space, and the maintenance lamp is stacked on the side wall of the case when in the docking position, and the side wall stands upright relative to the side of the bottom plate away from the room. In this way, the maintenance lamp is arranged close to the side wall when in the docking position, and will not affect other components in the body, and the maintenance lamp is less likely to be exposed to water mist or dust.

[0012] In one embodiment, the maintenance lamp is stacked on the side of the bottom plate away from the room when in the parking position. In this way, when the maintenance lamp is in the parking position, the maintenance lamp occupies less space in the vertical direction of the bottom plate in the fuselage.

[0013] In one embodiment, the periphery of the bottom plate includes a first side and a second side disposed opposite to each other, and the bottom plate is provided with a vent, and the fuselage can be equipped with an air dispatching device for connecting to the vent, wherein

[0014] The ventilation opening is provided on the first side and the maintenance lamp is adjacent to the second side in the working position; or,

[0015] The distance from the vent to the first side is smaller than the distance from the vent to the second side, and the maintenance lamp is adjacent to the second side in the working position.

[0016] With such arrangement, the influence of the air flow and wind beam flowing through the vents on the maintenance lamp is weakened. For example, when the ceiling appliance with maintenance function runs the beauty therapy function and the indoor heating function at the same time, the influence of the hot air blown out of the vents on the maintenance lamp is weakened, and the maintenance lamp is not easily burned by the high-temperature airflow and becomes ineffective.

[0017] In one embodiment, a storage space for accommodating a maintenance lamp is provided in the fuselage, and the storage space runs through the fuselage on one side facing the indoor room and forms a light outlet. When the maintenance lamp is in a working position, the light-emitting side emits maintenance light through the light outlet toward the indoor room.

[0018] In one embodiment, the light-emitting side faces away from the indoor space when the maintenance lamp is in the parking position. In this way, the light-emitting side is weakened by the moist air or dust from the room when the maintenance lamp is in the parking position, and the risk of failure and damage is reduced.

[0019] In one embodiment, when the maintenance lamp is in the working position, the light-emitting side does not protrude from the side of the fuselage facing the room. In this way, when the maintenance lamp is in the working position, it will not affect the user under the fuselage.

[0020] In one embodiment, when the maintenance lamp is in the docking position, the side of the maintenance lamp facing away from the light-emitting side does not protrude from the side of the fuselage facing the room. In this way, when the maintenance lamp is in the docking position, it will not affect the user under the fuselage.

[0021] In one embodiment, the projection of the light outlet on the parallel surface of the ceiling plate matches the projection of the maintenance lamp in the working position on the parallel surface of the ceiling plate. With this arrangement, the opening size of the light outlet is appropriate, which not only meets the need of the maintenance lamp to emit maintenance light into the room when in the working position, but also does not waste the surface of the fuselage facing the room due to an overly large opening, and can more easily plan ventilation holes, functional parts, etc. on the side of the fuselage facing the room.

[0022] In one embodiment, the projection of the light outlet on the parallel surface of the ceiling plate matches the projection of the maintenance lamp in the parking position on the parallel surface of the ceiling plate. In this way, when the maintenance lamp is in the parking position, the bottom of the ceiling appliance with maintenance function is more complete for indoor users, and the visual effect is better.

[0023] In one embodiment, a shield is movably provided on the body, and the shield closes the light outlet when the maintenance lamp is in the resting position, and opens the light outlet when the maintenance lamp is in the working position. With such a configuration, the shield can prevent dust, water mist and other substances in the room from spreading into the maintenance lamp and the body through the light outlet when the maintenance lamp is in the resting position, and the shield will not affect the maintenance lamp from normally emitting maintenance light into the room when it is in the working position.

[0024] In one embodiment, the shield is rotatably disposed on the fuselage.

[0025] In one embodiment, when the maintenance lamp is in the working position, the shield is at least partially stored inside the fuselage; and / or, when the maintenance lamp is in the working position, the shield is at least partially docked on the part of the fuselage located on the far side of the ceiling plate. In this way, when the maintenance lamp is in the working position, the shield can reduce its exposure in the room, thereby avoiding the adhesion of dust, moisture and other impurities in the room. When the shield closes the light outlet, the shield will not cause significant pollution to the maintenance lamp or the inside of the fuselage.

[0026] In one embodiment, the light-emitting side protrudes from the side of the body facing the room and enters the room when the maintenance lamp is in the working position. In this way, the light-emitting side is closer to the user's skin when the maintenance lamp is in the working position, so that the skin can be irradiated and maintained more efficiently and intensively.

[0027] In one embodiment, the maintenance lamp is rotatably arranged on the fuselage, and can be rotated relative to the fuselage to switch between a working position and a parking position. With such an arrangement, the maintenance lamp can switch between positions more quickly and easily.

[0028] In one embodiment, the axis of rotation of the maintenance lamp relative to the fuselage is not perpendicular to the ceiling panel.

[0029] In one embodiment, the maintenance lamp includes a lamp board and a light-emitting body arranged on the lamp board, and the lamp board is rotatably connected to the fuselage.

[0030] With this arrangement, the maintenance lamp integrates more light-emitting bodies, and the overall structure of the maintenance lamp is thinner and lighter.

[0031] In one embodiment, the fuselage has a rotation space for accommodating the maintenance lamp, and the rotation space runs through the fuselage to form a light outlet on one side facing the room, and the light-emitting side faces the room through the light outlet when the maintenance lamp is in the working position. With this arrangement, the maintenance lamp will not affect the user under the fuselage when rotating.

[0032] In one embodiment, there are multiple maintenance lamps, and when at least two maintenance lamps are in the working position, the light-emitting sides of the two maintenance lamps are arranged adjacent to each other. In this way, when at least two maintenance lamps are in the working position, the light-emitting sides of these maintenance lamps jointly form a whole light-emitting surface, and the maintenance light emitted by the multiple maintenance lamps is more concentrated, so that the radiation energy reaches the user's skin surface more concentratedly.

[0033] In one embodiment, each maintenance lamp includes a backlight side disposed opposite to the respective light-emitting side, and when at least two maintenance lamps are in the parking position, the backlight sides of the two maintenance lamps are disposed adjacent to each other. In this way, when at least two maintenance lamps are in the parking position, the backlight sides of the maintenance lamps together form a whole backlight surface, thereby realizing a close arrangement of multiple maintenance lamps, which can increase the maintenance lamp capacity, that is, allowing the fuselage to carry more maintenance lamps.

[0034] In one embodiment, each maintenance lamp is independently rotatably arranged on the body, and can be independently rotated relative to the body to switch between a working position and a parking position. This arrangement allows the user to selectively turn on or off some maintenance lamps according to usage needs, so that the ceiling appliance with maintenance function produces different radiation light emission modes in different usage occasions or purposes, so that the efficiency and radiation intensity of radiation maintenance have a multi-level adjustment function.

[0035] In one embodiment, the maintenance lamp is movably arranged on the fuselage, and can be moved relative to the fuselage to switch between the working position and the parking position. With such arrangement, the maintenance lamp can be switched between the working position and the parking position more conveniently and easily.

[0036] In one embodiment, the maintenance lamp is arranged on the body in a manner that it can be raised and lowered along the vertical direction of the ceiling plate. In this way, the maintenance lamp can adjust the distance from itself to the user below the body by raising and lowering relative to the body, thereby adjusting the distance from the light-emitting side to the user's skin surface, so that the radiation maintenance efficiency can be adjusted in multiple levels as the maintenance lamp rises and falls.

[0037] In one embodiment, the maintenance lamp is slidably arranged on the body in a direction parallel to the ceiling plate. In this way, when the maintenance lamp moves relative to the body, it will not affect the user under the body. In addition, the position of the light-emitting side can be changed in the horizontal direction, thereby changing the position and irradiation area of ​​the maintenance light beam emitted by the light-emitting side into the room.

[0038] In one embodiment, a storage space for accommodating the maintenance lamp is provided in the fuselage, and the storage space penetrates the fuselage to form a light outlet for the light-emitting side to face the room, and a sliding fit is formed between the maintenance lamp and the inner wall surface of the storage space. With such a configuration, the maintenance lamp can better maintain a stable posture when moving in the storage space, thereby performing a more precise position change, avoiding obvious posture changes during the movement process, so that the light-emitting side of the maintenance lamp can maintain a stable direction, thereby meeting the needs of users to adjust the distance between the maintenance lamp and themselves and at the same time maintain a stable irradiation direction of the maintenance light beam.

[0039] In one embodiment, a storage space for accommodating the maintenance lamp is provided in the fuselage, and the storage space penetrates the fuselage to form an entrance and exit for the maintenance lamp to pass through, and the maintenance lamp is slidably matched with the inner wall surface of the storage space. In this arrangement, the maintenance lamp can maintain its own posture stability when passing through the entrance and exit to switch the posture state, thereby ensuring the stability of the direction of the light-emitting side, so that the maintenance lamp can still keep the irradiation direction of the maintenance light stable after multiple posture changes.

[0040] In one embodiment, the maintenance lamp includes a lamp board and a light emitter arranged on the lamp board, and the lamp board is movably connected to the fuselage. In this way, the maintenance lamp integrates more light emitters, and the overall structure of the maintenance lamp is thinner and lighter.

[0041] In one embodiment, a shifter and / or a commutator connected to the maintenance lamp is also included, wherein the shifter is used to drive the maintenance lamp to change position to approach or move away from the ceiling space, and the commutator is used to drive the maintenance lamp to change posture to change the direction of the light-emitting side. With such a configuration, the maintenance lamp can change position and / or posture. When the maintenance lamp is compatible with position change and posture change, multi-dimensional adjustment of the maintenance lamp can be achieved, so that the maintenance lamp in different posture states can form a good coordinated match with the fuselage.

[0042] In one embodiment, the maintenance lamp further includes a shifter and a commutator connected to the maintenance lamp, the maintenance lamp is rotatably connected to the commutator, the shifter includes an output member movably arranged on the body, a driver connected to the output member, the commutator is installed on the output member, and the driver is used to drive the output member to move along a preset moving track. With such a configuration, the position change and posture change of the maintenance lamp will not conflict with each other, the driving of the maintenance lamp by the shifter will not cause the posture change of the maintenance lamp, and the driving of the maintenance lamp by the commutator will not cause the position change of the maintenance lamp, so the posture change efficiency of the maintenance lamp is improved and the change difficulty is reduced.

[0043] In one embodiment, the fuselage includes a base plate facing the indoor room, wherein the maintenance lamp can be driven by a driver to a middle position of the base plate close to the indoor side, and the commutator is used to drive the maintenance lamp to rotate when the maintenance lamp is in the middle position.

[0044] With such arrangement, the posture change process of the maintenance light is smoother and safer, and the action control logic used to control the posture change of the maintenance light is simple. The maintenance light can switch to the working posture in the order of position change first and then posture change, and can switch to the parking posture in the order of posture change first and then position change, so there will be no interference between the maintenance light and the fuselage.

[0045] In one embodiment, the output member includes a rack, the rack is movably arranged on the fuselage along a preset moving track, the commutator is fixedly connected to the rack, and the driver includes a gear meshing with the rack. With such a configuration, the shifter can drive the maintenance lamp to move smoothly relative to the fuselage, the position change accuracy of the maintenance lamp is higher, and it is not easy to produce a large position change error, so that the maintenance lamp can maintain a high position accuracy in both the working position and the parking position.

[0046] In one embodiment, the maintenance lamp includes a heat storage portion, which is parked on a portion of the body located on the far side of the ceiling plate when the maintenance lamp is in the parked position. In this way, when the maintenance lamp is in the parked position, the heat can be dissipated into the ceiling space through the heat storage portion, thereby helping the maintenance lamp to cool down and dissipate heat to avoid overheating and failure.

[0047] In one embodiment, when the maintenance lamp is in the parking position, the heat storage part is located on the side of the maintenance lamp away from the body. In this way, the heat storage part can more smoothly exchange heat with the air in the ceiling space.

[0048] In one embodiment, the heat storage part is provided with a heat sink, and the heat sink is located in the ceiling space when the maintenance lamp is in the parking position. In this way, the heat sink can increase the heat exchange rate between the heat storage part and the air in the ceiling space. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0072] 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.

[0073] The utility model provides a ceiling appliance 100 with a maintenance function, comprising a body 10 and a maintenance lamp 20 movably arranged on the body 10. The ceiling appliance 100 with a maintenance function has both a beauty maintenance function and an indoor 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.

[0074] 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.

[0075] 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.

[0076] See also Figure 1 , Figure 2 , Figure 5 , Figures 13 to 20 The body 10 can be set on the ceiling plate, and the body 10 includes a bottom side facing the room and the ground when the body 10 is installed on the ceiling plate. Figure 2-Figure 3 , Figure 5 , Figure 6 to Figure 12 , Figures 13 to 20 The maintenance lamp 20 is movably arranged on the fuselage 10, and includes a light-emitting side 201 for emitting maintenance light to radiate energy to human skin. The posture state of the maintenance lamp 20 at least includes a working posture and a parking posture. When the light-emitting side 201 emits maintenance light, the maintenance lamp 20 is in the working posture, and when the light-emitting side 201 stops emitting maintenance light, the maintenance lamp 20 is in the parking posture. The maintenance lamp 20 switches between the working posture and the parking posture by moving relative to the fuselage 10.

[0077] In some embodiments, the maintenance lamp 20 includes a lamp board 21 and a light-emitting body 22 disposed on one side of the lamp board 21, the light-emitting side 201 includes a side of the lamp board 21 on which the light-emitting body 22 is disposed, and the maintenance lamp 20 also includes a backlight side 202, which is a side of the lamp board 21 that is away from the light-emitting body 22 and serves as a heat storage part of the maintenance lamp 20, and the heat storage part heats up when the light-emitting body 22 emits maintenance light.

[0078] In some embodiments, the maintenance lamp 20 includes a lamp board 21 and a light-emitting body 22 disposed on both sides of the lamp board 21. The light-emitting side 201 includes two sides of the lamp board 21 on which the light-emitting body 22 is disposed. The lamp board 21 itself serves as a heat storage part of the maintenance lamp 20 and heats up when the light-emitting body 22 emits maintenance light.

[0079] See also Figure 4-5 , Figure 8 , Fig.12 , Figure 14-15 , Fig.18 and Fig. 20 When the maintenance lamp 20 is in the working position, the light emitting side 201 and the bottom side of the maintenance lamp 20 are facing the room; Figure 1 , Figure 3 , Figure 6 , Fig. 9 , Fig.13 , Figure 16-17 , Fig.19 When the maintenance lamp 20 is in the parking position, at least a portion of the maintenance lamp 20 is withdrawn from the room and stops emitting maintenance light.

[0080] In some embodiments, when the maintenance lamp 20 is in the docked position, at least a portion of the maintenance lamp 20 is stored inside the fuselage 10; in other embodiments, when the maintenance lamp 20 is in the docked position, at least a portion of the maintenance lamp 20 is docked on the fuselage 10 on the far side of the ceiling panel, the far side of the ceiling panel being the side of the ceiling panel facing away from the room and the ground, so that at least a portion of the maintenance lamp 20 is withdrawn into the ceiling space; in yet other embodiments, when the maintenance lamp 20 is in the docked position, at least a portion of it is stored in the fuselage 10, and at least a portion of it is withdrawn into the ceiling space.

[0081] The utility model of the ceiling appliance 100 with maintenance function realizes that the maintenance lamp 20 is in different posture states under different usage conditions. When the maintenance and beauty function is not enabled, at least a part of the maintenance lamp 20 is evacuated from the room and transferred to at least one of the body 10 and the ceiling space, thereby reducing the exposure time of the maintenance lamp 20 to the indoor humid gas environment, thereby improving the reliability and durability of the maintenance lamp 20, reducing the risk of failure of the maintenance lamp 20, and helping to improve or maintain the performance and efficacy of the maintenance lamp 20.

[0082] In some embodiments, the ceiling appliance 100 with maintenance function is used in a bathroom, and at least a portion of the body 10 is installed in the ceiling space between the ceiling plate and the ceiling of the bathroom, and the bottom side is exposed to the ground through the ceiling through-hole on the ceiling plate. Figure 4-5 , Figure 8 , Fig.12 , Figure 14-15 , Fig.18 and Fig. 20 When the maintenance lamp 20 is in the working position, the light-emitting side 201 and the bottom side are facing the ground. At this time, the maintenance lamp 20 can radiate energy to the user under the fuselage 10.

[0083] See also Figure 1 , Figures 13 to 20In some embodiments, the body 10 includes a bottom plate 12 and a chassis 11. The bottom plate 12 is installed on a side of the chassis 11 close to the room. The bottom side includes a side of the bottom plate 12 away from the chassis 11 and close to the room and the ground. The bottom side may further include an edge of the chassis 11 relatively close to the room and the ground. The chassis 11 may be set on a ceiling board. The chassis 11 is provided with a wind driving part and an air duct. The wind driving part can drive the air entering the chassis 11 to accelerate and form an airflow, and make the airflow flow along the air duct. Figure 5 , Figures 17 to 20 The body 10 is provided with a vent, which includes an air outlet 125 opened on the bottom side and connected to the downstream end of the air duct. Driven by the wind driving part, the airflow formed in the air duct is finally discharged from the air outlet 125 to the chassis 11 and blown into the room.

[0084] Optionally, in some embodiments, when the fuselage 10 is arranged in place in the ceiling space, the bottom side, the light-emitting side 201 and the side of the ceiling board close to the ground are all planes, and the bottom side extends in the horizontal direction, and when the maintenance lamp 20 is in the working position, the light-emitting side 201 extends in the horizontal direction. Of course, the light-emitting side 201 can also be tilted relative to the horizontal direction when the maintenance lamp 20 is in the working position.

[0085] Furthermore, in some embodiments not shown in the figure, the vent further includes an air inlet connected to the air inlet end of the wind drive unit or to the upstream end of the air duct. After the wind drive unit is started, air is sucked into the chassis 11 from the air inlet, then flows along the air duct and is finally discharged from the air outlet 125. The air inlet can be connected to the room to absorb indoor air, or connected to the outdoors to absorb outdoor air.

[0086] Optionally, the air inlet is opened on the bottom side and connected to the room, thereby realizing the circulation and reuse of indoor air. When the air inlet is opened on the bottom plate 12, the bottom plate 12 is an air collecting plate.

[0087] Optionally, in some embodiments, the air outlet 125 is opened on the bottom plate 12 and passes through one side of the bottom plate 12 close to the room and the other side away from the room; in other embodiments, the air outlet 125 may also be adjacent to the bottom plate 12, for example, the peripheral edge 124 of the bottom plate 12 is spaced from the edge or side wall 111 of the chassis 11 to form the air outlet 125; in addition, the air inlet may also be adjacent to the bottom plate 12, for example, the edge of the bottom plate 12 is spaced from the edge of the chassis 11 to form an air inlet.

[0088] Optionally, the fuselage 10 is also provided with a heating device (not shown) for heating the airflow. The heating device can be arranged in the air duct, in the wind drive part, or at the air outlet 125. The heating device is used to make the airflow generated by the wind drive part become warm airflow to achieve indoor heat preservation or heating.

[0089] In some embodiments, when the maintenance lamp 20 is in the docking position, the maintenance lamp 20 is docked on the side of the bottom plate 12 away from the interior and withdrawn from the interior space. The bottom plate 12 can block impurities such as water mist and dust in the interior space, thereby reducing the contact between the maintenance lamp 20 in the docking position and impurities.

[0090] In some embodiments, a storage space 13 is provided inside the fuselage 10 and is formed on a side of the bottom plate 12 away from the room. The storage space 13 runs through the fuselage 10 so that the maintenance lamp 20 can pass through and leave or withdraw into the storage space 13. When the maintenance lamp 20 is in the working position, the maintenance lamp 20 leaves the storage space 13, and when the maintenance lamp 20 is in the parking position, at least a portion of the maintenance lamp 20 withdraws into the storage space 13.

[0091] In other embodiments, a storage space 13 is provided inside the fuselage 10 and is formed on the side of the bottom plate 12 away from the indoor space. When the maintenance lamp 20 is in the working position and when the maintenance lamp 20 is in the docking position, the maintenance lamp 20 is located in the storage space 13.

[0092] Therefore, at least when the maintenance and beauty function is not enabled, the maintenance lamp 20 is withdrawn into the storage space 13 to reduce the contact between the maintenance lamp 20 and water mist, dust and other substances in the external environment of the fuselage 10, thereby extending the service life of the maintenance lamp 20 and maintaining good performance and efficacy of the maintenance lamp 20.

[0093] In other embodiments, the storage space 13 may be eliminated, and the maintenance lamp 20 may be withdrawn into the ceiling space outside the fuselage 10 when in the docked position. Preferably, at least a portion of the fuselage 10 is located on the side of the ceiling board away from the ground, and can carry the maintenance lamp 20 in the docked position.

[0094] Optionally, in some embodiments, the inner cavity of the chassis 11 forms a storage space 13, and the storage space 13 is partially closed by the bottom plate 12; an entrance and exit 123 connecting the storage space 13 and the indoor space is opened on the bottom side, and the entrance and exit 123 is for the maintenance lamp 20 to pass through when switching its position, so that the maintenance lamp 20 can travel back and forth between the storage space 13 and the indoor space.

[0095] Specifically, the entrance and exit 123 can be opened on the bottom plate 12, and the entrance and exit 123 connects the side of the bottom plate 12 facing the room and the side away from the room to connect the storage space 13 with the room. The entrance and exit 123 can also be adjacent to the bottom plate 12, for example, the peripheral edge 124 of the bottom plate 12 is spaced apart from the edge or side wall 111 of the chassis 11 to form the entrance and exit 123.

[0096] Optionally, in some embodiments, the inner cavity of the chassis 11 forms a storage space 13, and a light outlet 122 connecting the storage space 13 with the indoor space is opened on the bottom side. The maintenance lamp 20 is located in the storage space 13 both in the working position and in the docked position. When the maintenance lamp 20 is in the working position, the light-emitting side 201 of the maintenance lamp 20 faces the indoor space through the light outlet 122 and emits maintenance light into the indoor space.

[0097] It can be understood that the light outlet 122 can be opened on the bottom plate 12 and pass through the side of the bottom plate 12 facing the room and the other side away from the room, or it can be adjacent to the bottom plate 12, for example, the peripheral edge 124 of the bottom plate 12 is spaced apart from the edge or side wall 111 of the chassis 11 to form the light outlet 122.

[0098] Optionally, in some embodiments, the maintenance lamp 20 does not protrude from the bottom side when in the working position. Specifically, the maintenance lamp 20 may not protrude from the side of the bottom plate 12 facing the indoor room. Preferably, the maintenance lamp 20 is flush with the bottom side or the side of the bottom plate 12 facing the indoor room when in the working position. In other embodiments, the maintenance lamp 20 may also protrude from the bottom side when in the working position.

[0099] Optionally, in some embodiments, the maintenance lamp 20 does not protrude from the bottom side when it is in the docked position, and the maintenance lamp 20 may specifically not protrude from the side of the bottom plate 12 facing the indoor room. Preferably, when the maintenance lamp 20 is in the docked position, the light-emitting side 201 faces away from the ground, the backlight side 202 faces the indoor room and the ground, and the backlight side 202 is flush with the bottom side or the side of the bottom plate 12 facing the indoor room.

[0100] See also Figure 1 to Figure 5 , Figures 13 to 18 In some embodiments, the bottom plate 12 is away from the chassis 11 and forms a bottom side facing the indoor side. The projections of the bottom plate 12 and the maintenance lamp 20 in the working position projected onto the parallel surface of the ceiling board do not overlap each other, and the parallel surface of the ceiling board is a horizontal plane.

[0101] See also Figures 13 to 18 In some embodiments, the bottom plate 12 is provided with a light outlet 122. After the bottom plate 12 is projected onto a parallel surface of the ceiling plate, the contour formed by the projection of the light outlet 122 is a first contour. The contour of the maintenance lamp 20 in a working position projected onto a parallel surface of the ceiling plate is a second contour located within the first contour. The projections of the bottom plate 12 and the maintenance lamp 20 in a working position projected onto a parallel surface of the ceiling plate do not overlap with each other. Preferably, the first contour matches the second contour.

[0102] See also Figure 3 to Figure 5In some embodiments, the projection of the bottom plate 12 on the parallel surface of the ceiling plate is the plate surface projection, and the projection of the maintenance lamp 20 in the working position on the parallel surface of the ceiling plate is the light projection, which is located at the outer edge of the plate surface projection, and the parallel surface of the ceiling plate is a horizontal plane. Preferably, the light projection and the plate surface projection do not overlap, and the two are adjacent and connected.

[0103] See also Figure 15-16 In some embodiments, the maintenance lamp 20 is stacked with the base plate 12 when in the docking position, and is stacked on a side of the base plate 12 away from the room. Figure 15-16 In the illustrated embodiment, the maintenance lamp 20 is located in the storage space 13 when in the working position, and is stacked with the bottom plate 12 .

[0104] See also Figure 1 and Figure 3 , Figure 3 The ceiling appliance 100 with maintenance function shown does not show the chassis 11. When the maintenance lamp 20 is in the docking position, the maintenance lamp 20 and the side wall 111 of the chassis 11 are stacked in sequence, and the side wall 111 stands upright on the side of the bottom plate 12 away from the room. Preferably, when the maintenance lamp 20 is in the docking position, it fits closely with the side wall 111, and either the side wall 111 or the maintenance lamp 20 in the docking position can be perpendicular to the bottom plate 12 or not.

[0105] The periphery 124 of the bottom plate 12 includes a first side 1241 and a second side 1242 that are disposed opposite to each other, and the bottom plate 12 is provided with a vent, and the fuselage 10 can be equipped with or has been equipped with an air dispatching device for connecting the vent, and the air dispatching device includes a wind driving part and an air duct. In some embodiments, the vent is provided at the first side 1241, and the maintenance lamp 20 is adjacent to the second side 1242 in the working position; in other embodiments, the distance from the vent to the first side 1241 is less than the distance from the vent to the second side 1242, and the maintenance lamp 20 is adjacent to the second side 1242 in the working position.

[0106] See also Figure 5 , Figure 5 In the illustrated embodiment, the ventilation opening includes an air outlet 125 opened on the base plate 12, the distance from the air outlet 125 to the first side 1241 is smaller than the distance from the air outlet 125 to the second side 1242, the second side 1242 is provided with an entrance and exit 123, and the maintenance lamp 20 is adjacent to the second side 1242 in the working position, thereby avoiding the hot air flow blown out from the air outlet 125.

[0107] See also Figures 13 to 20In some embodiments, the storage space 13 passes through the bottom side of the body 10 facing the indoor room and forms a light outlet 122. The light-emitting side 201 emits maintenance light toward the indoor room through the light outlet 122 at least when the maintenance lamp 20 is in the working position.

[0108] Further, see Figure 15-16 When the maintenance lamp 20 is in the docked position, the light-emitting side 201 faces away from the indoor space, and the backlight side 202 arranged opposite to the light-emitting side 201 faces the indoor space through the light outlet 122 when the maintenance lamp 20 is in the docked position.

[0109] Further, see Figures 13 to 18 In some embodiments, when the maintenance lamp 20 is in the working position, the light-emitting side 201 does not protrude from the fuselage 10 and is used to face the bottom side of the room; in some embodiments, when the maintenance lamp 20 is in the docking position, the backlight side 202 disposed opposite to the light-emitting side 201 does not protrude from the fuselage 10 and is used to face the bottom side of the room.

[0110] Further, see Figures 15-16 , Figure 19-20 In some embodiments, when the chassis 11 is arranged in place in the ceiling space, the bottom side and the ceiling panel are extended in the horizontal direction, and the projection of the light outlet 122 on the parallel surface of the ceiling panel matches the projection of the maintenance lamp 20 in the working position on the parallel surface of the ceiling panel.

[0111] See again Figures 15-16 , Figure 19-20 In some embodiments, when the chassis 11 is arranged in place in the ceiling space, the bottom side and the ceiling panel are extended in the horizontal direction, and the projection of the light outlet 122 on the parallel surface of the ceiling panel matches the projection of the maintenance lamp 20 in the docking position on the parallel surface of the ceiling panel.

[0112] In some embodiments, the ceiling appliance 100 with maintenance function further includes a shield 50 movably disposed on the body 10. When the maintenance lamp 20 is in the parking position, the shield 50 closes at least a portion of the light outlet 122. When the maintenance lamp 20 is in the working position, the shield 50 opens the light outlet 122. The shield 50 blocks indoor impurities such as water mist and dust from contacting the maintenance lamp 20, which helps to extend the service life of the maintenance lamp 20 and maintain the performance and efficacy of the maintenance lamp 20.

[0113] The shielding member 50 can be rotatably connected to the fuselage 10, such as Figure 13-14 , Figure 17-18As shown, the shielding member 50 may also be movably or slidably connected to the body 10; the shielding member 50 may be connected to the chassis 11 or the bottom plate 12; the number of shielding members 50 may be one or more. In some embodiments not shown in the figure, the shielding member 50 may be a plate-shaped member parallel to the bottom plate 12 and the ceiling plate, and may be moved relative to the body 10 in a direction parallel to the bottom plate 12 to open or cover and close the light outlet 122.

[0114] In some embodiments, when the maintenance lamp 20 is in the working position, the shield 50 is at least partially stored inside the fuselage 10. Figure 13-14 , Figure 17-18 A storage space 13 is formed in the body 10, and the storage space 13 is connected to the light outlet 122 opened on the bottom side. When the maintenance lamp 20 is in the working position, the cover 50 is stored in the storage space 13. When the maintenance lamp 20 is in the docking position, the cover 50 closes the light outlet 122 to block the storage space 13 from the indoor space.

[0115] In some embodiments not shown in the figures, when the maintenance lamp 20 is in the working position, the shielding member 50 is no longer stored in the fuselage 10, but is at least partially docked on a portion of the fuselage 10 located on the far side of the ceiling panel, that is, the shielding member 50 is at least partially withdrawn into the ceiling space.

[0116] In some embodiments not shown in the figures, the light-emitting side 201 of the maintenance lamp 20 protrudes from the side of the body 10 facing the indoor room and enters the indoor space when the maintenance lamp 20 is in the working position. For example, the light-emitting side 201 can extend from the light outlet 122 and protrude from the side of the bottom plate 12 close to the indoor room and the ground when the maintenance lamp 20 is in the working position, thereby shortening the distance between the light-emitting side 201 and the user to enhance the irradiation effect.

[0117] See also Figure 1 to Figure 4 , Figures 13 to 18 In some embodiments, the maintenance lamp 20 is rotatably arranged relative to the fuselage. The maintenance lamp 20 is switched between a working position and a parking position by rotating relative to the fuselage. The orientation of the light-emitting side 201 can also change with the rotation of the maintenance lamp 20, thereby changing the irradiation direction and irradiation area position of the maintenance light emitted by the light-emitting side 201 to meet the user's adjustable requirements for the irradiation direction and irradiation area position of the maintenance light.

[0118] See also Figure 6 to Figure 12 , Figures 13 to 18 In some embodiments, when the fuselage 10 is arranged in place on the ceiling board, the axis of rotation of the maintenance lamp 20 relative to the fuselage 10 is not perpendicular to the ceiling board. Preferably, the axis of rotation of the maintenance lamp 20 relative to the fuselage 10 is parallel to the ceiling board. In this way, the force distribution of the pivoting part of the maintenance lamp 20 directly or indirectly connected to the fuselage 10 can be uniform.

[0119] See also Figures 13 to 18 In some embodiments, the storage space 13 inside the fuselage 10 forms a rotation space 131, and the rotation space 131 allows the maintenance lamp 20 to rotate in the rotation space 131. The maintenance lamp 20 is located in the rotation space 131 when it is in the working position and in the docking position. The rotation space 131 passes through the fuselage 10 and is used to face the bottom side of the room to allow the maintenance light to be projected into the room.

[0120] See also Figure 17-18 In some embodiments, there are multiple maintenance lamps 20, each of which has its own working position and parking position. When at least two of the maintenance lamps 20 are in the working position, the light-emitting sides 201 of the two maintenance lamps 20 are arranged side by side.

[0121] Figure 17-18 In the illustrated embodiment, the rotation axes of the plurality of maintenance lamps 20 are arranged in rows at intervals in a direction parallel to the bottom side and the ceiling panel. When the maintenance lamps 20 are in a working position, the maintenance lamps 20 are adjacent to each other side by side, and all the light-emitting sides 201 are flattened to form a light-emitting surface.

[0122] In some embodiments, the maintenance light 20 is movably disposed on the fuselage 10 and can move relative to the fuselage 10 to switch between a working position and a docking position.

[0123] Optionally, the maintenance lamp 20 includes a lamp board 21 and a plurality of light-emitting bodies 22 laid on the side of the lamp board 21, the light-emitting side 201 faces the ground and is formed by the light-emitting bodies 22 and the side of the lamp board 21. The maintenance lamp 20 moves relative to the fuselage 10 along a trajectory parallel to the bottom side and the horizontal direction, and can also move relative to the fuselage 10 along a trajectory not parallel to the bottom side and the horizontal direction.

[0124] Preferably, the maintenance lamp 20 is movably mounted on the body 10 in a direction perpendicular to the ceiling plate, so that it can move along a trajectory parallel to the vertical direction and change the distance between the light-emitting side 201 and the ground.

[0125] Optional, see Figure 19-20 A storage space 13 for accommodating the maintenance lamp 20 is provided in the fuselage 10. The storage space 13 runs through the bottom side of the fuselage 10 to form a light outlet 122. The light outlet 122 is for the light-emitting side 201 to emit maintenance light into the room when the maintenance lamp 20 is in a working position. The maintenance lamp 20 slides with the inner wall surface of the storage space 13, thereby maintaining the posture stability of the maintenance lamp 20 and ensuring that the direction of the light-emitting side 201 will not change as the maintenance lamp 20 moves.

[0126] In some embodiments, a storage space 13 for accommodating a maintenance lamp 20 is provided in the fuselage 10 . The storage space 13 passes through the fuselage 10 to form an entrance and exit 123 for the maintenance lamp 20 to pass through when switching its position. The maintenance lamp 20 slides in cooperation with the inner wall surface of the storage space 13 .

[0127] Optionally, the entrance and exit 123 can be opened on the peripheral side of the fuselage 10, for example, on the peripheral side of the chassis 11, and the maintenance lamp 20 slides horizontally in a direction parallel to the bottom side and the ceiling panel to move out of or into the storage space 13, and the light-emitting side 201 is always located on the side of the maintenance lamp 20 close to the ground.

[0128] In some embodiments, the ceiling appliance 100 with maintenance function further includes a driving unit connected to the maintenance lamp 20, and the driving unit includes any one or both of a shifter 30 and a commutator 40. The shifter 30 is used to drive the maintenance lamp 20 to move and change its position so that the light-emitting side 201 is close to or away from the room and the user, and the commutator 40 is used to drive the maintenance lamp 20 to rotate so that the maintenance lamp 20 changes its posture, thereby adjusting the direction of the light-emitting side 201 and the irradiation direction of the maintenance light.

[0129] Optional, Figure 1 to Figure 4 , Figure 6 to Figure 12 In the illustrated embodiment, the driving unit includes a shifter 30 and a commutator 40. The maintenance lamp 20 is rotatably connected to the commutator 40. The shifter 30 includes an output member 32 movably disposed on the body 10, and also includes a driver 31 connected to the output member 32. The commutator 40 is mounted on the output member 32. The driver 31 is used to drive the output member 32 to move along a preset moving trajectory. When driven by the driver 31, the output member 32 drives the commutator 40 and the maintenance lamp 20 to move synchronously.

[0130] Optionally, the output member 32 includes a rack 321 movably disposed on the body 10 along a preset moving trajectory, the commutator 40 is fixedly connected to the rack 321 , and the driver 31 includes a gear 311 meshing with the rack 321 .

[0131] In some embodiments, the maintenance lamp 20 includes a heat storage part. When the maintenance lamp 20 includes a lamp board 21 and a light emitting body 22 disposed on the lamp board 21, the lamp board 21 serves as the heat storage part of the maintenance lamp 20. When the maintenance lamp 20 is in a docked position, the heat storage part is docked in the ceiling space on the side of the ceiling board away from the ground, so that the heat storage part can dissipate heat into the ceiling space, preventing heat from accumulating in the fuselage 10, and reducing the risk of failure of other components in the fuselage 10 due to heat.

[0132] Optionally, a light-emitting body 22 is provided on one side of the lamp board 21, and a heat storage part is formed on the other side. When the maintenance lamp 20 is in the docking position, the heat storage part formed by the side of the lamp board 21 away from the light-emitting body 22 is located on the side of the maintenance lamp 20 away from the fuselage 10, thereby alleviating the scorching of the fuselage 10 by the heat storage part and accelerating the heat dissipation of the heat storage part into the ceiling space.

[0133] Optionally, the heat storage part is also provided with a heat sink, which may be a fin thermally connected to the heat storage part. When the maintenance lamp 20 is in the docked position, the heat sink is located on the side of the maintenance lamp 20 away from the fuselage 10 and is located in the ceiling space.

[0134] Next, combine Figures 1 to 20 The specific composition, structure and operation mechanism of the ceiling appliance 100 with maintenance function of the present invention are described in detail.

[0135] Embodiment 1

[0136] See also Figure 1 to Figure 5 The ceiling appliance 100 with maintenance function includes a shifter 30 and a commutator 40. The maintenance lamp 20 includes a lamp board 21 and a plurality of light-emitting bodies 22 arranged on the side of the lamp board 21. The light-emitting bodies 22 and the side of the light board 21 on which the light-emitting bodies 22 are arranged form a light-emitting side 201. After the body 10 is arranged in place in the ceiling space, the bottom plate 12 and the bottom side are extended horizontally, and a storage space 13 is formed in the chassis 11. A strip-shaped notch is opened on the peripheral edge 124 of the bottom plate 12 to form an entrance and exit 123 connecting the storage space 13 and the indoor space. The storage space 13 is a flat rectangular space that can accommodate a plate-like structure.

[0137] Specifically, the chassis 11 includes at least one side wall 111 , and the side wall 111 may be perpendicular to a side of the bottom plate 12 away from the indoor space, or may be inclined relative to a side of the bottom plate 12 away from the indoor space. Figure 1 In the illustrated embodiment, the chassis 11 includes four side walls 111 perpendicular to the horizontal plane, the storage space 13 is adjacent to the side walls 111, and the maintenance lamp 20 is stacked side by side with the side walls 111 when in the docked position. The maintenance lamp 20 can be either close to the side walls 111 or spaced apart from the side walls 111.

[0138] Figure 3 , Figure 6 and Fig. 9 In the illustrated embodiment, there is only one maintenance lamp 20 and the maintenance lamp 20 is shown in a docked position. The side wall 111 facing and arranged side by side with the maintenance lamp 20 is not shown. Preferably, when the maintenance lamp 20 is withdrawn into the storage space 13 and overlapped on the side wall 111 of the chassis 11, the lamp panel 21 of the maintenance lamp 20 extends in the vertical direction.

[0139] exist Figure 1 to Figure 5On the basis of the embodiment shown, the number of the maintenance lamps 20 can be increased to two, three or more. For example, if the number of the maintenance lamps 20 is two, the side wall 111 includes a first side wall and a second side wall disposed opposite to each other, and when the two maintenance lamps 20 are in the parking position, they are respectively stacked on the side of the first side wall close to the second side wall and the side of the second side wall close to the first side wall; when the two maintenance lamps 20 are in the working position, the two maintenance lamps 20 are respectively located at two opposite edges of the peripheral edge 124.

[0140] Figure 1 to Figure 5 In the illustrated embodiment, the bottom side is a horizontal plane parallel to the ceiling board. When the maintenance lamp 20 is in a working position, the figure of the maintenance lamp 20 projected on the parallel plane of the ceiling board is adjacent to the figure of the bottom plate 12 projected on the same parallel plane. When the maintenance lamp 20 is in a working position, the heights of the maintenance lamp 20 and the bottom plate 12 in the vertical direction may be the same or different.

[0141] See also Figure 2 The commutator 40 is a commutation motor, the light board 21 is rotatably connected to the output shaft of the commutation motor, the shifter 30 includes an output member 32 and a driver 31, the driver 31 includes a drive motor installed on the body 10, and a gear 311 installed on the output shaft of the drive motor, the output member 32 can be a rack 321, the rack 321 is movable relative to the body 10 and meshes with the gear 311, the commutation motor is fixedly connected to the rack 321, and the rack 321 moves relative to the body 10 according to a preset moving trajectory.

[0142] The driving motor drives the rack 321 to move along a preset moving trajectory through the gear 311. The commutator 40 and the maintenance light 20 follow the rack 321 and move relative to the fuselage 10 along the preset moving trajectory. The commutator 40 is responsible for driving the maintenance light 20 to rotate relative to the rack 321 so that the maintenance light 20 rotates relative to the fuselage 10.

[0143] See again Figure 5 The bottom plate 12 is provided with an air outlet 125, and the chassis 11 is provided with a wind driving part and an air duct. The wind driving part is used to drive the air to accelerate so as to form an airflow in the air duct. The air outlet 125 is connected with the air duct so that the airflow in the air duct is blown into the room. Specifically, the periphery 124 of the bottom plate 12 includes a first side 1241 and a second side 1242 that are arranged opposite to each other. The air outlet 125 is adjacent to the first side 1241, and the inlet and outlet 123 is opened on the second side 1242. The maintenance lamp 20 in the working position is adjacent to the second side 1242. With such a configuration, the maintenance lamp 20 can avoid the warm airflow blown out by the air outlet 125 when in the working position.

[0144] In some other embodiments, for example, the maintenance lamp 20 is movably disposed on the body 10 and can be horizontally moved along the extension direction of the bottom side, the air outlet 125 and the inlet and outlet 123 can also be Figure 5 In the arrangement shown, the air outlet 125 and the inlet and outlet 123 are respectively opened on the first side 1241 and the second side 1242 of the peripheral edge 124. The first side 1241 and the second side 1242 are arranged opposite to each other.

[0145] Two switching action modes are described below in which the commutator 40 and the shifter 30 cooperate to switch the maintenance lamp 20 from the parking position to the working position:

[0146] The first switching action mode: maintenance light 20 Figure 3 , Figure 6 In the docking position shown, the bottom plate 12 is docked in the storage space 13 away from the indoor side, and the lamp panel 21 is vertically extended and stacked side by side with the side wall 111. When it is necessary to switch to the working position, the driver 31 first drives the rack 321 to move vertically downward along the preset moving trajectory to switch to the working position. Figure 7 In the state shown, the maintenance lamp 20 reaches the middle section of the bottom plate 12 near the indoor side, Figure 6 The status shown is Figure 7 During the state switching period shown, the commutator 40 does not move, the maintenance lamp 20 and the rack 321 are relatively stationary, and the Figure 7 At the beginning of the state shown, the driver 31 stops, the commutator 40 operates and drives the maintenance lamp 20 to rotate relative to the rack 321 and the body 10 until it switches to Figure 4 , Figure 8 The state shown, at this time the maintenance lamp 20 is in the working position;
