[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 a maintenance lamp, which is used to emit maintenance light to radiate energy to human skin and perform skin care treatment, thereby producing beauty and healing effects. Existing Yuba usually adopts a design in which the maintenance lamp is fixedly installed on the body panel, which results in the maintenance light beam irradiation direction and irradiation area position being fixed, and cannot meet the user's demand for adjustable beam irradiation direction and irradiation area position. Utility Model Content

[0003] In view of this, the utility model provides a ceiling appliance with maintenance function that can support the position change of a maintenance lamp to provide a variety of light-emitting directions, thereby meeting the user's demand for adjustable maintenance lamp irradiation direction and irradiation area position.

[0004] The utility model provides a ceiling appliance with a maintenance function, which includes a body, a maintenance lamp and a drive unit.

[0005] The utility model has the following beneficial effects: the maintenance lamp can be driven by a driving unit to move relative to the fuselage, and the direction of the light-emitting part changes as the maintenance lamp rotates, and no longer maintains a single direction. Different directions of the light-emitting part correspond to different maintenance light irradiation directions and irradiation area positions, thereby being able to meet the user's needs for adjustable maintenance light irradiation directions and irradiation area positions.

[0006] In one embodiment, the maintenance lamp can be driven by a commutator to switch between a working position and a parking position, and when the maintenance lamp is in the working position, the light emitting portion faces indoors, and

[0007] When the maintenance lamp is in the docking position, the maintenance lamp is at least partially stored in the fuselage; and / or, when the maintenance lamp is in the docking position, the maintenance lamp is at least partially docked on a side of the ceiling panel away from the room.

[0008] With such an arrangement, the maintenance lamp can be at least partially evacuated from the room when in the docked position, thereby reducing the time the maintenance lamp is exposed to the humid indoor environment and reducing the contact between the humid air and the maintenance lamp, which is beneficial to improving the reliability and durability of the maintenance lamp and enhancing or maintaining the performance and efficacy of the maintenance lamp.

[0009] In one embodiment, the body includes a bottom plate for facing the room, and the maintenance lamp is parked at a side of the bottom plate facing away from the room when in the parking position. In this way, the maintenance lamp is in a cleaner position when in the parking position, and is not easily affected by dust and has reduced reliability and durability.

[0010] In one embodiment, the maintenance lamp is parked at the side of the bottom plate facing away from the room when in the parking position, and is erected relative to the side of the bottom plate facing away from the room. In this way, when the maintenance lamp is in the parking position, the maintenance lamp occupies less space on the side of the bottom plate facing away from the room in the extension direction of the bottom plate, thereby reducing the difficulty of arranging other components or structures on the side of the bottom plate facing away from the room.

[0011] In one embodiment, the body further comprises a case disposed on a side of the bottom plate away from the room, and when the maintenance lamp is in the docked position, it is stacked on a side wall of the case, and the side wall is arranged at an angle to the bottom plate. In this way, the maintenance lamp in the docked position occupies less space in the extension direction of the bottom plate.

[0012] In one embodiment, the body has a rotation space for accommodating the maintenance lamp, the rotation space runs through the body and is used to form a light outlet on one side facing the room, and the light emitting part 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 body when it rotates.

[0013] In one embodiment, the working position includes a first working position and a second working position, and the light emitting part includes a first light emitting part and a second light emitting part. When the maintenance lamp is in the first working position, the first light emitting part is located on the peripheral side of the body and faces the room, and when the maintenance lamp is in the second working position, the second light emitting part is stacked on the side of the body close to the room and faces the room. With such a configuration, the position of the light emitting part and the emission position of the maintenance light are no longer single and fixed, but can be selected and adjusted. The maintenance lamp can switch positions to meet the different needs of users for the light emission position and irradiation position of the maintenance light.

[0014] In one embodiment, the first light emitting part and the second light emitting part are arranged opposite to each other, and the commutator is used to drive the maintenance lamp to rotate so as to switch the maintenance lamp between the first working position and the second working position. With this arrangement, the position of the light emitting part and the emission position of the maintenance light can be adjusted more conveniently and quickly.

[0015] In one embodiment, a vent is provided on one side of the body facing the room, and includes a first side and a second side disposed opposite to each other, and the commutator can drive the maintenance lamp to the working position, wherein: the distance from the vent to the first side is smaller than the distance from the vent to the second side, the maintenance lamp is adjacent to the second side when in the working position, and the light-emitting portion faces the room; or, the vent is provided on the first side, the maintenance lamp is adjacent to the second side when in the working position, and the light-emitting portion faces the room. With such a configuration, the influence of the airflow and wind beam flowing through the vent 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 vent on the maintenance lamp is weakened, and the maintenance lamp is not easily burned by the high-temperature airflow and becomes ineffective.

[0016] In one embodiment, the driving unit further comprises a shifter connected to the maintenance light.

[0017] The shifter is used to drive the maintenance light to move relative to the fuselage so as to move in and out of the fuselage; and / or,

[0018] The shifter is used to drive the maintenance lamp to move relative to the fuselage so as to move in and out of the side of the ceiling panel away from the room.

[0019] With such an arrangement, the maintenance lamp can change position and posture when switching positions, realizing multi-dimensional adjustment and orderly position change of the maintenance lamp, and making it easier to form good coordination between the maintenance lamp and the fuselage in different position states.

[0020] In one embodiment, the maintenance lamp is rotatably connected to the commutator, the shifter includes an output member and a driver, the output member is movably arranged on the body and equipped with the commutator, and the driver is connected to the output member to drive the output member to move. With such an arrangement, the position change and attitude change of the maintenance lamp do not conflict, the position drive of the maintenance lamp by the shifter does not cause the attitude change of the maintenance lamp, and the drive of the maintenance lamp by the commutator does not cause the position change of the maintenance lamp, and the position change efficiency of the maintenance lamp is improved.

[0021] In one embodiment, the output member is a rod-shaped member, wherein

[0022] The moving track direction of the output member is the same as the length direction of the output member; and / or,

[0023] The commutator is fixedly connected to the end of the output member relatively close to the chamber; and / or,

[0024] The driver can drive the output member to approach and move away from the room. When the output member approaches the room, the connection position between the output member and the driver is transferred from the end of the output member close to the room to the end of the output member far from the room.

[0025] In one embodiment, the driver is disposed on a side of the housing close to the room; and / or,

[0026] The output member comprises a rack which is movably arranged relative to the machine body, a commutator is arranged on the rack, and a driver comprises a gear meshing with the rack.

[0027] With such arrangement, the final position at which the driver drives the output member and the maintenance lamp to move indoors is closer to the ground, thereby minimizing the distance between the maintenance lamp and the ground when the driver drives the output member to the lowest point. The risk of interference with the fuselage caused by the commutator driving the maintenance lamp when the output member and the maintenance lamp are closest to the ground is reduced, and the driver driving the output member will not affect the connection between the commutator and the output member.

[0028] In one embodiment, an entrance and exit is opened on the side of the fuselage facing the room, and the driver drives the output member to pass through the entrance and exit to approach and move away from the room; and / or, the moving track direction of the output member is perpendicular to at least one of the side of the fuselage facing the room and the ceiling panel. With such a configuration, the position switching process of the maintenance lamp is smooth, the action control logic of the maintenance lamp position switching is simple, the maintenance lamp can switch from the parking position to the working position in the action sequence of first position change and then posture change, and can switch from the working position to the parking position in the action sequence of first posture change and then position change, so the maintenance lamp will not interfere with the fuselage.

[0029] In one embodiment, the fuselage is provided with a storage space, the storage space runs through the fuselage, and the storage space is used for the maintenance lamp to switch between withdrawing into the storage space and leaving the storage space; or, the storage space accommodates at least part of the maintenance lamp. In this way, the maintenance lamp can be more fully protected, at least when the maintenance lamp is in the docked position, the maintenance lamp can be less exposed to water mist and dust, which helps to extend the service life of the maintenance lamp and improve or maintain the performance and efficacy of the maintenance lamp.

[0030] In one embodiment, the body includes a chassis and a bottom plate, the chassis is formed with a storage space and is located on a side of the bottom plate away from the room, and the bottom plate is provided with an entrance and exit connected to the storage space for the maintenance lamp to pass through. With this arrangement, the maintenance lamp can be withdrawn into and out of the storage space more conveniently, thereby enabling faster and more efficient position switching.

[0031] In one embodiment, when the maintenance lamp is withdrawn into the storage space, it is stacked side by side with the side wall of the chassis, and the side wall is arranged at an angle to the bottom plate. In this way, the maintenance lamp in the docking position occupies less space in the extension direction of the bottom plate, which can leave more space for the chassis to arrange other components in the chassis.

[0032] In one embodiment, the fuselage has a bottom plate facing indoors, and the maintenance lamp includes a lamp panel. When the maintenance lamp is in a working position, the lamp panel is not perpendicular to the bottom plate.

[0033] In one embodiment, when the maintenance lamp is in the working position, the lamp plate is parallel to the bottom plate. In this way, the light spot area of ​​the maintenance light emitted by the light emitting part irradiating the human skin is maximized, so that the human skin can receive the radiation energy of the maintenance lamp to the greatest extent.

[0034] In one embodiment, when the maintenance lamp is in the working position, the maintenance lamp is located outside the fuselage. This arrangement makes it easier to set the functional modules on the bottom plate. When the maintenance lamp is in the working position, the maintenance lamp and the functional modules arranged on the bottom plate can operate simultaneously, and these functional modules are not affected by the maintenance lamp, and accordingly, the functional modules will not affect the maintenance lamp.

[0035] In one embodiment, when the maintenance lamp is in the working position, the maintenance lamp is located at the periphery of the bottom plate. With this arrangement, when the maintenance lamp is in the working position, the vertical space occupied by the ceiling-mounted electrical appliance with maintenance function does not change significantly compared to when the maintenance lamp is in the parking position, which is conducive to maintaining the adequacy of the internal space of the bathroom and is convenient for users.

The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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 introduced below by taking a heater equipped with maintenance lamp 20 as an example.

[0068] The fuselage 10 can be arranged on a ceiling plate, and the fuselage 10 includes a bottom side 121 facing the room when the fuselage 10 is arranged on the ceiling plate. Figure 1 to Figure 6 , Figure 14 to Figure 17 The body 10 includes a bottom plate 12, 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 121 includes a side of the bottom plate 12 facing the room. The maintenance lamp 20 is rotatably arranged relative to the body 10, and includes a light-emitting portion 201 for emitting maintenance light to radiate energy to human skin. The position of the maintenance lamp 20 relative to the body 10 at least includes a working position and a parking position. When the light-emitting portion 201 emits maintenance light, the maintenance lamp 20 is in the working position, and when the light-emitting portion 201 stops emitting maintenance light, the maintenance lamp 20 is in the parking position.

[0069] In some embodiments, the maintenance lamp 20 includes a lamp board 21 and a light-emitting body 22. The light-emitting body 22 may be one or more. A plurality of light-emitting bodies 22 may be randomly dispersedly laid on one side or both sides of the lamp board 21, or may be arranged in a queue or array on one side or both sides of the lamp board 21. The light-emitting portion 201 includes the light-emitting body 22 and a side surface of the lamp board 21 on which the light-emitting body 22 is disposed.

[0070] Optionally, in some embodiments, one or more light-emitting bodies 22 are provided on only one side of the lamp board 21 , and the maintenance lamp 20 further includes a backlight portion 202 disposed opposite to the light-emitting portion 201 , and the backlight portion 202 includes a side of the lamp board 21 facing away from the light-emitting body 22 .

[0071] The driving unit at least includes a commutator 40 connected to the maintenance lamp 20. The commutator 40 is used to drive the maintenance lamp 20 to at least rotate relative to the body 10 so as to switch between the working position and the parking position. The direction of the light emitting part 201 also changes as the maintenance lamp 20 rotates relative to the body 10, so that the irradiation direction and the irradiation area position of the maintenance light change as the position of the maintenance lamp 20 changes. The working position and the parking position of the maintenance lamp 20 correspond to the activation and termination of the maintenance and beauty function, respectively.

[0072] Specifically, see Figure 5-6 , Fig.14 When the maintenance lamp 20 is in the working position, the light emitting portion 201 and the bottom side 121 face the room, and the light emitting portion 201 can emit maintenance light into the room; see Figure 2 , Figure 4 , Figure 16-17 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 parked on the side of the bottom plate 12 away from the room and stops emitting maintenance light.

[0073] In some embodiments, when the maintenance lamp 20 is in the working position, the lamp board 21 is not perpendicular to the base plate 12. Optionally, when the maintenance lamp 20 is in the working position, the lamp board 21 is parallel to the base plate 12 and the ceiling plate. In some embodiments, when the maintenance lamp 20 is in the working position, the maintenance lamp 20 is located on the outside of the fuselage 10. In some embodiments, when the maintenance lamp 20 is in the working position, the maintenance lamp 20 is located on the peripheral edge 124 of the base plate 12. Preferably, the maintenance lamp 20 is adjacent to the peripheral edge 124 at this time.

[0074] 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 at a portion of the ground side of the ceiling panel, the ground 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 side of the ceiling panel facing away from the room.

[0075] It is worth noting that the maintenance lamp 20 can not only be used for maintenance and beauty, but also can be used as a regular lighting lamp in some occasions, that is, the maintenance lamp 20 has both the functions of maintenance and beauty and the regular internal lighting of the bathroom. Of course, an additional lighting lamp can also be provided for the ceiling appliance 100 with maintenance function.

[0076] In some embodiments, the bottom side 121 is exposed through the ceiling through hole on the ceiling plate and faces the ground, the bottom side 121 and the ceiling plate are parallel to the horizontal direction, and when the maintenance lamp 20 is in the working position, the bottom side 121 and the light-emitting portion 201 are horizontally extended toward the ground. In other embodiments, when the maintenance lamp 20 is in the working position, the light-emitting portion 201 can also be tilted relative to the horizontal direction.

[0077] The ceiling appliance 100 with maintenance function of the utility model allows the maintenance lamp 20 to rotate relative to the body 10 so that the light-emitting part 201 maintains different orientations under different usage conditions, and allows the maintenance lamp 20 to be removed from the bathroom when the maintenance and beauty function is not enabled, thereby reducing the exposure of the maintenance lamp 20 to the high temperature and high humidity environment in the bathroom, helping to improve the reliability and durability of the maintenance lamp 20, reducing the risk of failure of the maintenance lamp 20, and enabling the maintenance lamp 20 to improve or maintain performance and efficacy.

[0078] See also Figure 16-17 In some embodiments, the body 10 also includes a chassis 11. When the chassis 11 is arranged in place in the ceiling space, the bottom plate 12 is installed on a side of the chassis 11 relatively close to the room. The bottom side 121 includes a side of the bottom plate 12 away from the chassis 11. The bottom side 121 may further include an edge of the chassis 11 close to the room. An air drive unit 17 and an air duct 16 are provided in the chassis 11. The air drive unit 17 can drive and accelerate air to form airflow, and make the airflow flow along the air duct 16 to flow out of the body 10, and finally blow into the room to achieve the function of dispatching air to the indoor space.

[0079] The chassis 11 includes a side wall 111 for surrounding the wind drive unit 17 and the air duct 16. The side wall 111 is vertically or obliquely erected relative to the side of the bottom plate 12 away from the room. There are multiple side walls 111. When the chassis 11 is arranged in place on the ceiling panel, the side wall 111 is at least partially arranged in the ceiling space.

[0080] It should be noted that when the maintenance lamp 20 is parked at the side of the ceiling board away from the room at the parking position, the maintenance lamp 20 can be located outside the chassis 11 and exposed in the ceiling space. Preferably, the maintenance lamp 20 is parked at the outer wall surface of the side wall 111 at the parking position.

[0081] In some embodiments, the body 10 is provided with a vent, which includes an air inlet and / or an air outlet 125. The air inlet is connected to at least one of the upstream end of the air duct 16 and the wind drive unit 17, and the air outlet 125 is connected to the downstream end of the air duct 16 and the indoor space. Figure 14-15 The bottom side 121 is provided with an air outlet 125 connected to the air duct 16 and open to the indoor room. Driven by the wind driving unit 17, the air flow in the air duct 16 is discharged from the fuselage 10 through the air outlet 125 to blow into the indoor room.

[0082] The air inlet can be connected to both the indoor space and the outdoor space. When the air inlet is connected to the indoor space, the air inlet can be opened at the bottom side 121. When the air inlet is connected to the indoor space, the air drive unit 17 can drive the air to circulate between the indoor space and the fuselage 10. When the air inlet is connected to the outdoor space, the air drive unit 17 can obtain fresh air from the outdoor space and supply it to the indoor space.

[0083] Specifically, the air outlet 125 can be a through hole opened on the bottom plate 12 and penetrating the side of the bottom plate 12 close to the room and the side away from the room, or the air outlet 125 can be arranged adjacent to the edge 124 of the bottom plate 12. For example, the edge 124 of the bottom plate 12 can be spaced apart from the side wall 111 of the chassis 11, so that the air outlet 125 is formed between the edge 124 and the side wall 111.

[0084] Optionally, the wind driving unit 17 is a centrifugal fan. When the wind driving unit 17 is a centrifugal fan, the air duct 16 is arranged around the circumference of the centrifugal fan, and the wind wheel axis of the centrifugal fan is perpendicular to the bottom side 121 .

[0085] In some embodiments, the chassis 11 may be eliminated from the fuselage 10, and the side of the bottom plate 12 close to the indoor room forms the bottom side 121 of the fuselage 10. The elimination of the chassis 11 does not affect the arrangement of the air drive unit 17 and the air duct 16. For example, the air drive unit 17 is installed on the side of the bottom plate 12 away from the indoor room, the air duct 16 is arranged on the side of the bottom plate 12 away from the indoor room so that the air outlet of the air drive unit 17 is located at the upstream end of the air duct 16, and the air outlet 125 is opened on the bottom plate 12 to connect the downstream end of the air duct 16.

[0086] Furthermore, an air inlet connecting the air drive unit 17 and the indoor air is provided on the bottom side 121. Driven by the air drive unit 17, the indoor air is sucked into the chassis 11 through the air inlet, then accelerated in the air duct 16 to form an air flow, and then blown out from the air outlet 125. Optionally, the air inlet is provided on the bottom plate 12, and the bottom plate 12 provided with the air inlet is called an air collecting plate.

[0087] In other embodiments, the air inlet can also be opened at other positions of the fuselage 10 and does not have to be connected to the indoor space. For example, the air inlet can also be connected to the outdoor space. After the wind drive unit 17 is started, it can obtain air from the outdoors. The outdoor air passes through the air inlet - air duct 16 - air outlet 125 in sequence and then blows into the indoor space.

[0088] Optionally, the air outlet 125 can be opened on the bottom plate 12, or 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 of the chassis 11 to form an air outlet 125 adjacent to the bottom plate 12; the air inlet 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 of the chassis 11 to form an air inlet adjacent to the bottom plate 12.

[0089] Preferably, the air inlet and the air outlet 125 can be respectively opened on two opposite edges of the base plate 12, or the air inlet and the air outlet 125 can be respectively adjacent to two opposite edges of the base plate 12, so as to prevent the air entering the air inlet and the air flowing out of the air outlet 125 from interfering with each other.

[0090] Optionally, a heating device (not shown) for heating the airflow is further provided in the fuselage 10. The heating device can be arranged in the air duct 16, in the wind drive unit 17, or in the air outlet 125. The heating device is used to heat the airflow about to flow out of the air outlet 125 to make it warm air.

[0091] In some embodiments, a storage space 13 is provided in the body 10. Figure 5-6 , Figure 16-17 The storage space 13 is located on the side of the bottom plate 12 away from the room. The storage space 13 penetrates the body 10 to form an entrance 123 for the maintenance lamp 20 to pass through. The maintenance lamp 20 passes through the entrance 123 when switching positions. When the maintenance lamp 20 is in the parking position, at least part of the maintenance lamp 20 is withdrawn into the storage space 13, and when the maintenance lamp 20 is in the working position, the maintenance lamp 20 leaves the storage space 13 and is located outside the body 10. Therefore, when the maintenance and beauty function is not enabled, the exposure of the maintenance lamp 20 to the indoor environment can be reduced, which helps to extend the service life of the maintenance lamp 20.

[0092] 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 accommodated in the storage space 13.

[0093] Furthermore, the storage space 13 is formed by the inner cavity of the case 11, and the bottom plate 12 disposed on the side of the case 11 relatively close to the indoor part closes the storage space 13, and the bottom side 121 is provided with an entrance 123 connecting the storage space 13 with the indoor space. Specifically, the entrance 123 may be a through hole disposed on the bottom plate 12, and the entrance 123 connects the side of the bottom plate 12 close to the indoor part with the other side of the bottom plate 12 away from the indoor part, and the maintenance lamp 20 is partially or completely withdrawn into the storage space 13 on the side of the bottom plate 12 away from the indoor part when in the parking position, and is moved out of the case 11 when in the working position.

[0094] Optionally, when the fuselage 10 is arranged in place in the ceiling space, the side wall 111 and the maintenance lamp 20 that is in the docked position and withdrawn into the storage space 13 are stacked side by side, and an angle is formed between the side wall 111 and the bottom plate 12. The side wall 111 can be erected vertically relative to the side of the bottom plate 12 away from the room, or can be erected approximately vertically relative to the side of the bottom plate 12 away from the room. At this time, the maintenance lamp 20 can be spaced apart from the side wall 111, or can be attached to the side wall 111.

[0095] It can be understood that in other embodiments, when the fuselage 10 is arranged in place in the ceiling space, the side wall 111 is stacked side by side with the maintenance lamp 20 that is in the parking position and withdrawn into the ceiling space outside the fuselage 10. At this time, the maintenance lamp 20 can be spaced apart from the side wall 111 or attached to the side wall 111.

[0096] The present utility model does not limit whether the maintenance lamp 20 is located in the chassis 11 when it is in the docked position. As long as the maintenance lamp 20 is docked on the side of the bottom plate 12 away from the indoor room when it is in the docked position, the maintenance lamp 20 in the docked position can be upright on the bottom plate 12 or stacked with the bottom plate 12. When the maintenance lamp 20 is upright on the side of the bottom plate 12 away from the indoor room when it is in the docked position, the lamp panel 21 of the maintenance lamp 20 can be perpendicular to the bottom plate 12 or form a non-90° angle with the bottom plate 12.

[0097] Figure 16-17 In the illustrated embodiment, the chassis 11 includes four side walls 111, which form four sides of the rectangular fuselage 10. When the fuselage 10 is arranged in place in the ceiling space, the four side walls 111 extend in the vertical direction and are perpendicular to the bottom plate 12. In other embodiments, the side walls 111 may also form a non-90° angle with the bottom plate 12.

[0098] Optionally, the peripheral edge 124 of the bottom plate 12 is spaced from the edge of the chassis 11 relatively close to the room to form an entrance 123 for the maintenance lamp 20 to pass through. Compared with the entrance 123 formed by a through hole in the bottom plate 12, the entrance 123 formed between the peripheral edge 124 and the edge of the chassis 11 can make the maintenance lamp 20 closer to the side wall 111 when in the docked position, so as to leave space in the chassis 11 for arranging other components.

[0099] In some embodiments, the storage space 13 can be eliminated and the bottom plate 12 can be retained. When the maintenance lamp 20 is in the docking position, at least part of the maintenance lamp 20 is docked on the side of the bottom plate 12 away from the interior of the room. Finally, at least part of the maintenance lamp 20 is located in the ceiling space outside the fuselage 10.

[0100] See also Figure 2 , Figure 4-5 , Figure 14-15 , Figure 16-17 The periphery 124 of the bottom plate 12 includes a first edge 1241 and a second edge 1242 which are arranged opposite to each other, wherein the second edge 1242 is provided with a strip-shaped notch to form an entrance and exit 123, and the vent includes an air outlet 125 which is opened on the bottom plate 12 and connected to the air duct 16, and the distance from the air outlet 125 to the first edge 1241 is smaller than the distance from the air outlet 125 to the second edge 1242.

[0101] See also Figure 1 , Figure 3 , Figure 5-6 , Fig.16 In some embodiments, when the maintenance lamp 20 is in the working position, the maintenance lamp 20 and the bottom plate 12 are arranged adjacent to each other in the horizontal direction. Preferably, the bottom plate 12 is a flat plate structure, the side of the bottom plate 12 close to the room and the side of the bottom plate 12 away from the room are both horizontal planes, and the bottom side 121 is a horizontal plane. When the maintenance lamp 20 is in the working position, the maintenance lamp 20 is located at the periphery of the bottom plate 12, that is, the maintenance lamp 20 and the periphery of the bottom plate 12 are arranged adjacent to each other in the horizontal direction, and the light-emitting portion 201 is parallel to the horizontal direction.

[0102] It should be noted that the maintenance lamp 20 in the working position does not mean that the maintenance lamp 20 is at the same vertical height as the base plate 12. The light-emitting portion 201 can be coplanar with the bottom side 121, or can be located on the side of the base plate 12 away from the chassis 11, so that the light-emitting portion 201 protrudes from the bottom side 121 toward the ground when the maintenance lamp 20 is in the working position, so as to shorten the distance between the light-emitting portion 201 and the user under the body 10, thereby improving the absorption of the maintenance light energy by the human skin.

[0103] In some embodiments, when the maintenance lamp 20 is in the docked position, the distance from the light emitting portion 201 located on the side of the maintenance lamp 20 relatively close to the ground to the ground is greater than the distance from the bottom side 121 to the ground.

[0104] See also Figure 1 , Figure 3 , Figure 5 In some embodiments, the driving unit includes a commutator 40 and a shifter 30 connected to the maintenance lamp 20. The shifter 30 is used to drive the maintenance lamp 20 to move to change its position, so that the maintenance lamp 20 is at least partially withdrawn to the side of the bottom plate 12 away from the room, and the maintenance lamp 20 is moved away from the side of the bottom plate 12 away from the room. The commutator 40 is used to drive the maintenance lamp 20 to change its posture and adjust the direction of the light-emitting portion 201 to change the irradiation direction of the maintenance light.

[0105] The following describes the position switching process of the maintenance lamp 20 by taking the case where the entrance 123 is opened on the bottom side 121 as an example. When the maintenance lamp 20 switches from the parking position to the working position, the shifter 30 first drives the maintenance lamp 20 to move and pass through the entrance 123 to exit the side of the bottom plate 12 away from the room, and then the commutator 40 drives the maintenance lamp 20 to rotate so that the light-emitting part 201 faces the room; when the maintenance lamp 20 switches from the working position to the parking position, the commutator 40 first drives the maintenance lamp 20 to rotate so that the maintenance lamp 20 is aligned with the entrance 123, and then the shifter 30 drives the maintenance lamp 20 to move into the side of the bottom plate 12 away from the room.

[0106] In some embodiments, when the shifter 30 is actuated to move the maintenance light 20 into the side of the base plate 12 away from the room, the maintenance light 20 moves into the chassis 11, and when the maintenance light 20 moves out of the side of the base plate 12 away from the room, the maintenance light 20 moves out of the chassis 11 and then out of the entire body 10.

[0107] In other embodiments, when the shifter 30 is actuated to move the maintenance lamp 20 into the side of the base plate 12 away from the room, the maintenance lamp 20 moves into the ceiling space, and when the maintenance lamp 20 moves out of the side of the base plate 12 away from the room, the maintenance lamp 20 moves out of the ceiling space and is located under the ceiling plate.

[0108] Specifically, the shifter 30 includes an output member 32 and a driver 31 connected to the output member 32. The output member 32 is movably arranged relative to the fuselage 10 along a preset moving track. The commutator 40 is fixedly mounted on the output member 32. The maintenance lamp 20 is mounted on the commutator 40. The driver 31 is used to drive the output member 32 to move up and down relative to the fuselage 10 along the preset moving track, thereby driving the commutator 40 and the maintenance lamp 20 to move up and down together. The commutator 40 drives the maintenance lamp 20 to rotate relative to the output member 32 and the fuselage 10. When the maintenance lamp 20 is in the parking position, at least part of the output member 32 is parked on the side of the bottom plate 12 away from the room.

[0109] The driver 31 can drive the output member 32 to approach and move away from the room. Specifically, the driver 31 can drive the output member 32 to descend to increase the length of the output member 32 extending from the bottom side 121, so that the output member 32 is gradually moved out of the fuselage 10, and the driver 31 can drive the output member 32 to ascend to reduce the length of the output member 32 extending from the bottom side 121, so that the output member 32 is gradually moved into the side of the bottom plate 12 away from the room.

[0110] Preferably, the output member 32 can move in the entrance 123 under the drive of the driver 31 to approach and move away from the room and the ground. During the lifting and lowering process of the output member 32 along the preset moving trajectory, the commutator 40 does not move, and the output member 32 and the maintenance lamp 20 are relatively stationary.

[0111] Optional, see Figure 1 , Figure 3 , Figure 7 to Figure 13 The driver 31 includes a driving motor installed on the fuselage 10 and a gear 311 installed on the output shaft of the driving motor. The output member 32 may include a rack 321 meshing with the gear 311. The rack 321 forms a sliding connection with the fuselage 10 along a preset moving trajectory. The commutator 40 may be a commutation motor fixedly installed on the rack 321. The maintenance lamp 20 is connected to the output shaft of the commutation motor. The driving motor drives the rack 321 to move along the preset moving trajectory through the gear 311. The commutator 40 drives the maintenance lamp 20 to rotate relative to the rack 321 and the fuselage 10.

[0112] Optionally, the preset moving trajectory is a straight trajectory. When the fuselage 10 is arranged in place in the ceiling space, the preset moving trajectory is perpendicular to the ceiling panel and / or the bottom plate 12. The driver 31 drives the output member 32 to move vertically up and down along the preset moving trajectory. When the output member 32 includes a rack 321, the length direction of the rack 321 is the same as the extension direction of the preset moving trajectory. When the output member 32 includes other rod-shaped transmission members, the length direction of the output member 32 is the same as the extension direction of the preset moving trajectory.

[0113] Taking the output member 32 including the rack 321 as an example, one side of the rack 321 is provided with teeth for engaging the gear 311, and the other side is installed with a commutator 40. The driver 31 is installed on the side of the fuselage 10 relatively close to the indoor room. The commutator 40 is installed at the distal end of the output member 32 formed by the rack 321 or other rod-shaped transmission members, and can also be installed at the proximal end of the output member 32. The distal end and the proximal end are respectively one end of the output member 32 away from the indoor room and the ground and the other end of the output member 32 close to the indoor room and the ground.

[0114] See also Figure 7-Figure 8 , Figure 10 to Figure 13When the output member 32 is a rack 321 or other rod-shaped transmission member, the connection position of the output member 32 and the driver 31 is transferred from the end of the output member 32 close to the room to the end of the output member 32 away from the room as the driver 31 drives the output member 32 to descend in the direction close to the room, and is transferred from the end of the output member 32 away from the room to the end of the output member 32 close to the room as the driver 31 drives the output member 32 to rise in the direction away from the room. The shifter 30 may also include a friction wheel provided on the driver 31, and the output member 32 may also be replaced by a friction strip or other rod-shaped transmission element in contact with the friction wheel.

[0115] Furthermore, the opening of the entrance and exit 123 is roughly strip-shaped. When the fuselage 10 is arranged to be located in the ceiling space, when the maintenance lamp 20 is in the docked position, the lamp panel 21 extends in the vertical direction, and at least one of the light-emitting portion 201 and the backlight portion 202 is perpendicular to the bottom plate 12. At this time, the side of the maintenance lamp 20 close to the room and the side of the maintenance lamp 20 away from the room are arranged in sequence in the vertical direction. The driver 31 can drive the maintenance lamp 20 to move vertically downward along a preset moving trajectory so as to gradually move out of the fuselage 10 through the entrance and exit 123.

[0116] Optionally, the entrance and exit 123 is adjacent to one side of the base plate 12, and the entrance and exit 123 may also be formed by a notch opened on one side of the base plate 12. When the maintenance lamp 20 is in the docked position, the side of the maintenance lamp 20 relatively close to the room is at least partially exposed through the entrance and exit 123 and faces the room, and is arranged adjacent to the edge of the base plate 12 adjacent to the entrance and exit 123. Preferably, when the maintenance lamp 20 is in the docked position, the side of the maintenance lamp 20 close to the room occupies the entrance and exit 123 and is adapted to the edge of the base plate 12 adjacent to the entrance and exit 123.

[0117] The position of the maintenance lamp 20 relative to the fuselage 10 also includes a middle position. When the maintenance lamp 20 is in the middle position, the maintenance lamp 20 is completely removed from the fuselage 10 and is located on the side of the bottom plate 12 close to the room. At the same time, the lamp board 21 is still extended in the vertical direction, and the side of the maintenance lamp 20 close to the ground and the other side away from the ground are arranged in sequence in the vertical direction. The commutator 40 is activated when the maintenance lamp 20 reaches the middle position to drive the maintenance lamp 20 to rotate until the light-emitting portion 201 faces the room and the ground so that the maintenance lamp 20 is switched to the working position.

[0118] When the maintenance lamp 20 switches from the working position to the parking position, the commutator 40 first drives the maintenance lamp 20 to rotate relative to the output member 32 to restore the maintenance lamp 20 to the middle position. The maintenance lamp 20 in the middle position is vertically aligned with the opening of the entrance and exit 123, and then the commutator 40 stops running to keep the posture of the maintenance lamp 20 unchanged. The driver 31 drives the maintenance lamp 20 to rise vertically along a preset moving trajectory to pass through the entrance and exit 123 and gradually enter the storage space 13 until the maintenance lamp 20 is switched to the parking position again.

[0119] Furthermore, the maintenance lamp 20 has at least one intermediate stopping position relative to the rotational stroke of the commutator 40 and the output member 32, and the intermediate stopping position is located between the two extreme positions of the rotational stroke. When the maintenance lamp 20 is at one of the extreme positions of the rotational stroke, the maintenance lamp 20 is in the working position, and when the maintenance lamp 20 is at the other extreme position, the maintenance lamp 20 is in the middle position. When the maintenance lamp 20 reaches any intermediate stopping position, the commutator 40 can suspend operation to maintain the maintenance lamp 20 stationary at the intermediate stopping position.

[0120] Optionally, when the maintenance lamp 20 is in any intermediate docking position, the light-emitting part 201 is tilted toward the room and the ground. At this time, the light-emitting part 201 forms an angle with the horizontal direction and the vertical direction. Such a setting can further meet the user's diverse needs for the radiation direction of the maintenance light.

[0121] See also Fig.14 In some embodiments, after the fuselage 10 is arranged in the ceiling space, the peripheral edge 124 of the bottom plate 12 includes a first side 1241 and a second side 1242 that are arranged opposite to each other in the horizontal direction, the air outlet 125 is adjacent to the first side 1241, the inlet 123 is opened at the second side 1242, and the maintenance lamp 20 in the docking position is arranged in sequence with the bottom plate 12 in the horizontal direction, and the maintenance lamp 20 is adjacent to the second side 1242. Therefore, the warm air flow blown out from the air outlet 125 will not affect the maintenance lamp 20.

[0122] It is understood that in other embodiments, the air outlet 125 may also be opened on the first side 1241, and the inlet 123 may also be adjacent to the second side 1242. In particular, when the air outlet 125 is adjacent to the first side 1241 and the inlet 123 is adjacent to the second side 1242, 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.

[0123] In other embodiments, Fig.14 The air outlet 125 shown in the figure can also be replaced by an air inlet, and the air inlet can still be arranged according to Fig.14 The layout position of the air outlet 125 shown is opened.

[0124] 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. The two action modes are based on two different embodiments of the commutator 40 with maintenance function. Figure 7-Figure 8 , Figure 10 to Figure 13 :

[0125] The first action mode:

[0126] See also Figure 7 to Figure 9 The installation position of the commutator 40 on the rod-shaped output member 32 is located at the end of the output member 32 that is relatively far from the room. Figure 7 In the docking position shown, the bottom plate 12 is docked 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, and the rack 321 and the maintenance lamp 20 pass through the entrance 123 to switch to the working position. Figure 8 In the state shown, the maintenance lamp 20 is moved out of the fuselage 10 and is in the middle position. Figure 7 Towards Figure 8 During the switching period of the position shown, the commutator 40 does not move, the maintenance lamp 20 and the rack 321 are relatively stationary, Figure 8 At the beginning of the state shown, the driver 31 stops moving, the output member 32 remains stationary, the commutator 40 starts running and drives the maintenance lamp 20 to rotate relative to the rack 321 and the body 10 until it switches to Fig. 9 The state shown, at this time the maintenance lamp 20 is in the working position;

[0127] The second action mode:

[0128] See also Figure 10 to Figure 13 The installation position of the commutator 40 on the rod-shaped output member 32 is located at the end of the output member 32 relatively close to the room. Fig.10 In the docking position shown, the bottom plate 12 is docked on the side away from the room, and the lamp panel 21 extends vertically and overlaps 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 track, and the rack 321 and the maintenance lamp 20 pass through the entrance 123 to switch to the working position. Fig.11 In the position shown, the maintenance lamp 20 is moved out of the fuselage 10 and is in the middle position. Fig.10 Towards Fig.11 During the switching period of the position shown, the commutator 40 does not move, the maintenance lamp 20 and the rack 321 are relatively stationary, Fig.11 At the beginning of the state shown, the driver 31 stops moving, the output member 32 stops temporarily, the commutator 40 starts running and drives the maintenance lamp 20 to rotate relative to the rack 321 and the body 10 until it switches to Fig.12The state shown, at this time, the light-emitting portion 201 faces the room, and then the commutator 40 stops moving, and the driver 31 moves again and drives the rack 321 and the maintenance lamp 20 to move vertically upward along the preset moving trajectory for a certain distance to reduce the length of the rack 321 protruding from the bottom side 121, and the maintenance lamp 20 is vertically lifted along the rack 321 by the same distance, and finally the maintenance lamp 20 switches to Fig.13 Working position shown.

[0129] The action mode of the maintenance lamp 20 switching from the working position to the parking position is opposite to the action mode of the maintenance lamp 20 switching from the parking position to the working position, and will not be described here. It should be noted that the output member 32 is not limited to the rack 321, and the gear 311 installed on the output shaft of the driver 31 can also be replaced by other transmission elements, that is, the movement of the commutator 40 and the maintenance lamp 20 relative to the fuselage 10 along the preset moving trajectory can also be achieved through other transmission mechanisms, not limited to the gear 311 rack 321 transmission form, for example, the shifter 30 can be a push rod motor, and the commutator 40 is installed on the push rod of the push rod motor. After the push rod motor is started, it can control the push rod to extend and retract along the preset moving trajectory.

[0130] The maintenance lamp 20 generates a large amount of heat while emitting maintenance light, so the maintenance lamp 20 also includes a heat storage part 203 that accumulates heat. In some embodiments, the heat storage part 203 includes a backlight part 202, and specifically, the heat storage part 203 includes a side of the lamp board 21 that is away from the light emitter 22; in other embodiments, the maintenance lamp 20 includes a heat sink that is thermally connected to the lamp board 21, and the heat sink can be a fin or a convex column that is thermally connected to the backlight part 202. The heat storage part 203 includes the backlight part 202 and the heat sink, and the heat sink provides a larger heat dissipation surface area to help the heat dissipate quickly.

[0131] Furthermore, the body 10 also has a heat dissipation channel 15 connected to the storage space 13. The heat dissipation channel 15 can pass through the body 10 to communicate with the outside of the body 10, or can be connected to the air duct 16 to indirectly communicate with the outside of the body 10. When the maintenance lamp 20 is in the docking position, at least a portion of the maintenance lamp 20 is located in the storage space 13. More specifically, in some embodiments, when the maintenance lamp 20 is in the docking position, at least the heat storage portion 203 is located in the storage space 13.

[0132] With such arrangement, the residual heat of the maintenance lamp 20, i.e., mainly the heat of the heat storage part 203, can be diffused into the storage space 13 when the maintenance lamp 20 is in the docked position, and then the heat is directly dissipated to the outside of the fuselage 10 through the heat dissipation holes 15, or is dissipated to the air duct 16 and finally dissipated to the outside of the fuselage 10, or is dissipated to the outside of the fuselage 10 and the air duct 16 at the same time, thereby preventing the heat storage part 203 from continuously accumulating heat to reduce the temperature of the maintenance lamp 20, and can eliminate or alleviate overheating in the storage space 13, thereby preventing the residual heat of the maintenance lamp 20 from scorching some components inside the fuselage 10.

[0133] In some embodiments, at least a portion of the body 10 can be located in the ceiling space after the body 10 is arranged to be located on the ceiling panel, and the heat dissipation duct 15 is opened in the portion of the body 10 located in the ceiling space and communicated with the ceiling space. Specifically, the heat dissipation duct 15 can be opened in the chassis 11 and communicated with the storage space 13 in the chassis 11. When the body 10 is arranged in place in the ceiling space, the storage space 13 is communicated with the ceiling space outside the chassis 11 through the heat dissipation duct 15.

[0134] See also Figure 16-17 The side wall 111 includes a ventilation wall 1111 with a heat dissipation hole 15. Like other side walls 111, the ventilation wall 1111 is also perpendicular or approximately perpendicular to the bottom plate 12. When the maintenance lamp 20 is in the parking position, the heat storage part 203 including the backlight part 202 is located on the side of the maintenance lamp 20 relatively close to the ventilation wall 1111. Preferably, the backlight part 202 is arranged opposite to the ventilation wall 1111, and the light-emitting part 201 is located on the side of the maintenance lamp 20 away from the ventilation wall 1111.

[0135] Optionally, when the maintenance lamp 20 is in the docked position, it is stacked side by side with the air-permeable wall 1111 , and at this time, the lamp board 21 is approximately perpendicular to the bottom plate 12 , and the lamp board 21 is approximately parallel to the air-permeable wall 1111 .

[0136] Furthermore, the body 10 includes a partition 14 located inside the chassis 11, and the partition 14 divides the internal space of the chassis 11 into at least two parts. The space between one side of the partition 14 and the air-permeable wall 1111 forms a storage space 13, and the space of the chassis 11 located on the side of the partition 14 away from the air-permeable wall 1111 forms an air duct 16, which can be used to set up a wind drive unit 17. The heat dissipation channel 15 is opened in the partition 14 and passes through both sides of the partition 14 so that the air duct 16 and the storage space 13 are connected.

[0137] After airflow is formed in the air duct 16, the air pressure on the side of the partition 14 away from the storage space 13 decreases, that is, the air pressure in the storage space 13 is higher than the air pressure on the side of the partition 14 away from the storage space 13, and higher than the air pressure in the air duct 16. When a pressure difference is formed on both sides of the partition 14, the heat of the heat storage part 203 and the heat diffused into the storage space 13 will be transferred to the air duct 16 along with the air in the storage space 13 through the heat dissipation holes 15 opened in the partition 14, and finally flow out of the fuselage 10 along with the airflow in the air duct 16.

[0138] See also Figure 1 , Figure 3 and Figure 6 The partition 14 is a plate member perpendicular to or approximately perpendicular to the bottom plate 12, and the partition 14 is parallel to and spaced from one of the side walls 111, so that the partition 14, the maintenance lamp 20 in the parking position and the side wall 111 are stacked side by side in sequence. Preferably, the side wall 111 includes a ventilated wall 1111 with a heat dissipation hole 15, and the partition 14 also has a heat dissipation hole 15, and the partition 14, the maintenance lamp 20 in the parking position and the ventilated wall 1111 are arranged side by side in sequence.

[0139] When any two or three of the partition 14 , the maintenance lamp 20 in the parking position and the side wall 111 are arranged side by side, any one of the three can be perpendicular to the bottom plate 12 or approximately perpendicular to the bottom plate 12 .

[0140] In some embodiments, the chassis 11 can be eliminated and the bottom plate 12 and the partition 14 with the heat dissipation duct 15 can be retained. The heat dissipation duct 15 can still be connected to the air duct 16 on one side of the partition 14. The maintenance lamp 20 in the docking position is docked on the other side of the partition 14 and can still be stacked side by side with the partition 14. The heat dissipation duct 15 also runs through the side of the partition 14 away from the air duct 16.

[0141] Optionally, when the partition 14 is provided with a heat dissipation hole 15, when the maintenance lamp 20 is in the docked position, the heat storage portion 203 including the backlight portion 202 is arranged facing the side of the partition 14 away from the air duct 16, thereby reducing the difficulty and resistance of heat transfer and diffusion to the air duct 16.

[0142] Optionally, the vent includes an air outlet 125 opened on the bottom side 121, and the air outlet 125 connects the downstream end of the air duct 16 with the indoor space. After the heat of the heat accumulation part 203 is transferred to the air duct 16, the heat is discharged from the fuselage 10 through the air outlet 125 and flows into the room along with the air flow in the air duct 16.

[0143] In some embodiments, the body 10 includes a partition 14 located on the side of the bottom plate 12 away from the indoor room and inside the chassis 11, the heat dissipation channel 15 includes a first heat dissipation channel 15 opened in the partition 14, and also includes a second heat dissipation channel 15 opened in the side wall 111 of the chassis 11, part of the heat of the heat storage part 203 is transferred to the air duct 16, and the other part of the heat is transferred to the ceiling space.

[0144] The heat dissipation hole 15 is provided on the partition 14 so that the heat dissipation hole 15 is connected to the air duct 16. Not only can the residual heat of the heat storage part 203 be taken away promptly and quickly by the airflow in the air duct 16, but the residual heat of the heat storage part 203 can also be used to heat the airflow in the air duct 16, or the heat of the heat storage part 203 can be used as a supplement to indoor heating and heat preservation, so that the operating power of the heating device can be reduced to achieve the effect of saving power consumption in the warm air condition. In some use occasions, the heating device does not even need to be operated, and the airflow in the air duct 16 is heated by the residual heat of the heat storage part 203 to meet the user's needs.

[0145] In some embodiments, the wind drive unit 17 includes a centrifugal fan arranged in the chassis 11, and the partition 14 includes a volute surrounding the circumference of the centrifugal fan. The gap between the circumference of the centrifugal fan and the volute forms the air duct 16. The volute is provided with a heat dissipation channel 15 and forms the partition 14. After the centrifugal fan is started, it can drive the air to flow along the side of the volute close to the centrifugal fan. When the maintenance lamp 20 is in the docked position, it is located on the side of the volute away from the centrifugal fan.

[0146] In some embodiments, the maintenance lamp 20 also includes a decorative portion 204 and a functional part 23 arranged on the decorative portion 204. The functional part 23 is used to provide more auxiliary functions to enhance the ease of use of the ceiling appliance 100 with maintenance function. The functional part 23 may include any one or more of a lighting module, a status display module, and a touch module, and may also include other types of modules.

[0147] The lighting module is used to illuminate the room and generate light of a specific color to adjust the indoor tone and atmosphere. The status display module displays the various operating parameters and status indicators of the ceiling appliance 100 with maintenance function. The touch module allows users to touch and operate to switch the functional mode of the maintenance lamp 20, such as adjusting the energy radiation intensity and wavelength of the maintenance light, and adjusting the wind direction and temperature of the airflow blown out by the air outlet 125.

[0148] In some embodiments, the functional part 23 can be movably provided on the decorative portion 204, and can move relative to the decorative portion 204 to change its own position. For example, the functional part 23 can be a lighting module movably provided on the decorative portion 204, and the illumination direction of the lighting module can be changed by moving relative to the decorative portion 204. In some embodiments, the functional part 23 can be detachably provided on the decorative portion 204, so that the user can select the functional part 23 of personal preference and install it on the decorative portion 204.

[0149] In some embodiments, the functional part 23 may be removed from the decorative part 204, and the fuselage 10 is provided with an entrance 123 for the maintenance lamp 20 to pass through. When the maintenance lamp 20 is in the working position, it withdraws from the storage space 13 from the entrance 123 and reaches the outside of the fuselage 10, and the light-emitting part 201 faces the indoor. When the maintenance lamp 20 is in the docking position, it is at least partially stored in the storage space 13, and the decorative part 204 is located at the entrance 123 when the maintenance lamp 20 is in the docking position. Optionally, the entrance 123 is opened on the bottom side 121, for example, the bottom plate 12 is provided with an entrance 123 connecting the indoor space and the storage space 13.

[0150] In some embodiments, the functional part 23 may be removed from the decorative part 204, and the bottom side 121 is provided with an entrance 123 for the maintenance lamp 20 to pass through. When the maintenance lamp 20 is in the working position, it is withdrawn from the side of the bottom plate 12 away from the room and reaches the outside of the fuselage 10 through the entrance 123, and the light-emitting part 201 faces the room. When the maintenance lamp 20 is in the parking position, it is at least partially parked on the side of the bottom plate 12 away from the room, and the decorative part 204 is located at the entrance 123 when the maintenance lamp 20 is in the parking position. Optionally, the maintenance lamp 20 is at least partially withdrawn into the ceiling space when it is in the parking position.

[0151] Specifically, the entrance 123 can be opened on the bottom plate 12 and pass through both sides of the bottom plate 12, or it can be adjacent to the peripheral edge 124 of the bottom plate 12. For example, the fuselage 10 also includes a chassis 11, and the side of the bottom plate 12 facing away from the chassis 11 and the edge of the side wall 111 relatively close to the room together form the bottom side 121, and the peripheral edge 124 and the edge of the side wall 111 relatively close to the room are spaced apart to form the entrance 123.

[0152] In some embodiments, the modification portion 204 includes a water guide portion. When the maintenance lamp 20 is in the docked position, the water guide portion is connected to the opening edge of the entrance and exit 123, and the water guide portion now forms a water guide surface that extends and protrudes obliquely toward the room relative to the bottom side 121, so that droplets attached to the bottom side 121 can flow along the water guide surface and eventually drip, thereby reducing moisture near the opening of the entrance and exit 123. With this arrangement, the maintenance lamp 20 is not easily adhered to water droplets the next time it is extended from the entrance and exit 123 and switched to the working position.

[0153] In some embodiments, the decoration portion 204 includes a water guide portion. When the maintenance lamp 20 is in the docked position, the water guide portion is connected to the surface of the fuselage 10 and extends and protrudes outward at an angle relative to the fuselage 10. For example, the water guide portion is connected to a side of the bottom plate 12 close to the room, or is connected to an edge of the side wall 111 close to the room so as to protrude downward at an angle relative to the bottom side 121.

[0154] Due to the presence of the entrance 123, the area of ​​the bottom plate 12 close to the indoor side is limited, and the number and scale of other functional components or structures arranged on the bottom plate 12 are limited. The decorative portion 204 provides a layout position for the functional components 23, so that the ceiling appliance 100 with maintenance function can carry more functional components 23. Figure 2 , Figure 4 , Figure 14-15 In some embodiments, when the maintenance lamp 20 is in the docked position, the trimming portion 204 is disposed on the edge of the lamp panel 21 close to the interior and the ground.

[0155] Optionally, when the maintenance lamp 20 is in the parking position, the trimming portion 204 is matched with the opening edge of the entrance 123, and the trimming portion 204 closes the entrance 123, thereby preventing water mist and dust inside the bathroom from entering the body 10 through the entrance 123. The trimming portion 204 is arranged at the edge of the lamp panel 21 close to the room and the ground, and the opening shape of the entrance 123 is substantially the same as the edge shape of the trimming portion 204.

[0156] Optionally, when the maintenance lamp 20 is in the docked position, the trimming portion 204 does not protrude beyond the opening edge of the entrance and exit 123. Preferably, the trimming portion 204 does not protrude beyond the bottom side 121 when the maintenance lamp 20 is in the docked position, and the trimming portion 204 is flush with the opening edge of the entrance and exit 123.

[0157] Optionally, the side of the bottom plate 12 close to the indoor room and the ground is a plane, and when the maintenance lamp 20 is in the docking position, the decorative portion 204 and the side of the bottom plate 12 close to the indoor room are located in the same horizontal plane.

[0158] See also Fig.15 In some embodiments, the peripheral edge 124 includes a first edge 1241 and a second edge 1242 that are arranged opposite to each other in a horizontal direction, and the air outlet 125 is adjacent to the first edge 1241. When the maintenance lamp 20 is in the docked position, the entrance and exit 123 and the decorative portion 204 occupying the entrance and exit 123 are adjacent to the second edge 1242, and the air outlet 125 and the entrance and exit 123 are spaced apart in the horizontal direction.

[0159] With such arrangement, the warm air flow blown out from the air outlet 125 will not substantially affect the finishing portion 204 . When a functional component 23 is disposed on the finishing portion 204 , the warm air flow can also be prevented from burning the functional component 23 .

[0160] In some embodiments, the trimming portion 204 further includes a sealing edge. When the maintenance lamp 20 is in the docked position, the sealing edge is provided at the edge of the lamp board 21 relatively close to the room and the ground, and at this time, the sealing edge seals and closes the entrance 123. The sealing edge can be integrally formed on the lamp board 21, or it can be a convex edge formed by a sealing rubber ring or a sealing strip connected to the edge of the lamp board 21. Preferably, the sealing edge is adapted to the opening edge of the entrance 123 when the maintenance lamp 20 is in the docked position.

[0161] Optionally, when the sealing edge is a structure formed by a sealing rubber ring and a sealing strip and is formed separately from the light board 21 , the sealing edge is detachably connected to the edge of the light board 21 .

[0162] With such arrangement, the sealing edge can block water mist, dust, etc. in the indoor space from entering the body 10 through the entrance 123, thereby improving the service life and reliability of the ceiling appliance 100 with maintenance function.

[0163] In some embodiments, the maintenance lamp 20 is vertically erected relative to the bottom plate 12 and the bottom side 121 when in the docked position, and in other embodiments, the maintenance lamp 20 is approximately vertically erected relative to the bottom plate 12 and the bottom side 121 when in the docked position. In this way, when the maintenance lamp 20 moves downward from the side of the bottom plate 12 away from the room and switches to the working position, the edge of the entrance 123 will not interfere with the decoration part 204, so that the decoration part 204 and the functional parts 23 provided on the decoration part 204 can be prevented from being damaged.

[0164] exist Figure 1 to Figure 17 On the basis of the illustrated embodiment, the number of maintenance lamps 20 can also be increased to two, three or more. In some embodiments, the number of maintenance lamps 20 is two, the side wall 111 includes a first side wall 111 and a second side wall 111 that are opposite to each other and spaced apart, and when the two maintenance lamps 20 are in the docked position, they are respectively stacked on the side of the first side wall 111 close to the second side wall 111 and the side of the second side wall 111 close to the first side wall 111, and when the two maintenance lamps 20 are in the working position, the two maintenance lamps 20 are respectively adjacent to the two edges of the bottom plate 12 that are away from each other, and in the extension direction of the bottom side 121, the bottom plate 12 is located between the two maintenance lamps 20, and the three are arranged in sequence along the horizontal direction.

[0165] Figure 1 to Figure 17 In the illustrated embodiment, the figure of the light-emitting portion 201 projected onto the horizontal plane when the maintenance lamp 20 is in the working position does not overlap with the figure of the base plate 12 projected onto the same horizontal plane, so that the base plate 12 and the maintenance lamp 20 in the working position are side by side and adjacent in the horizontal direction.

[0166] Figure 18 to Figure 21In the illustrated embodiment, when the maintenance lamp 20 is in the working position, the pattern of the light-emitting portion 201 projected onto the horizontal plane and the pattern of the base plate 12 projected onto the same horizontal plane at least partially overlap and form an overlapping area, so that the maintenance lamp 20 and the base plate 12 are stacked in the vertical direction. Figure 18 to Figure 21 The ceiling appliance 100 with maintenance function shown in FIG. Figure 10 to Figure 13 The same as the ceiling appliance 100 with maintenance function shown in the figure, the commutator 40 drives the maintenance lamp 20 to rotate relative to the rack 321 at an angle of 90°. The difference lies in the action mode of the two. Figure 18 to Figure 21 The action mode of the embodiment shown is:

[0167] The installation position of the commutator 40 on the rod-shaped output member 32 is located at an end of the output member 32 that is relatively close to the room and the ground. Fig.18 In the docking position shown, the bottom plate 12 is docked in the storage space 13 away from the indoor and ground side, and the lamp panel 21 is kept vertically extended and stacked side by side with the side wall 111 of the chassis 11. 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, and the rack 321 and the maintenance lamp 20 pass through the entrance 123 to switch to the working position. Fig.19 In the position shown, the maintenance lamp 20 is moved out of the fuselage 10 and is in the middle position. Fig.18 Towards Fig.19 During the position switching period shown, the commutator 40 does not move, and the maintenance lamp 20 and the rack 321 are relatively stationary;

[0168] from Fig.19 The driver 31 stops moving, the output member 32 temporarily remains stationary, the commutator 40 starts running and drives the maintenance lamp 20 to rotate relative to the rack 321 and the body 10, so that the maintenance lamp 20 switches to Fig. 20 The light emitting portion 201 is facing the room and the ground. Next, the commutator 40 stops moving, and the driver 31 moves again and drives the rack 321 and the maintenance lamp 20 to move vertically upward along the preset moving trajectory for a certain distance to reduce the height of the rack 321 protruding from the bottom side 121. The maintenance lamp 20 is vertically lifted along the rack 321 by the same distance. Finally, the maintenance lamp 20 switches to Fig.21 Working position shown.

[0169] Figure 18 to Figure 21In the illustrated embodiment, an air outlet 125 connected to the air duct 16 is further provided on the bottom side 121 for blowing air into the room. When the maintenance lamp 20 is in the working position, the air flow beam flowing out from the air outlet 125 is closer to the light-emitting portion 201 in the horizontal direction, and the maintenance light and the air flow beam are more concentrated. When the temperature of the air flow blown out from the air outlet 125 is slightly higher than the room temperature, such an arrangement helps the user to receive the irradiation of the maintenance light while receiving the air flow, so as to obtain heat preservation and maintenance and beauty at the same time, and the air flow beam has a weak effect on the thermal radiation of the maintenance lamp 20 and can be ignored.

[0170] exist Figure 10 to Figure 13 , Figure 18 to Figure 21 On the basis of the illustrated embodiment, the following adjustments can be made: light-emitting bodies 22 are arranged on both sides of the lamp board 21, the light-emitting part 201 includes a first light-emitting part 201 and a second light-emitting part 201 arranged opposite to each other, the first light-emitting part 201 includes one side of the lamp board 21 and the light-emitting body 22 arranged on this side, the second light-emitting part 201 includes the other side of the lamp board 21 and the light-emitting body 22 arranged on the other side, the lamp board 21 serves as the heat storage part 203 of the maintenance lamp 20, the commutator 40 drives the maintenance lamp 20 to rotate relative to the rack 321 to expand the angular stroke to 180°, and the working positions include the following: Fig.13 The first working position shown in FIG. Fig.21 The second working position is shown.

[0171] For example, when the temperature of the air flow blown out of the air outlet 125 is significantly higher than the room temperature, the maintenance lamp 20 is driven by the commutator 40 to switch to Fig.13 In the first working position shown, the first light-emitting portion 201 is located at the peripheral edge 124 of the bottom plate 12 and faces the room, and the second light-emitting portion 201 faces away from the room and the ground, thereby eliminating or weakening the baking of the high-temperature airflow on the maintenance lamp 20; when the temperature of the airflow blown out of the air outlet 125 drops, the maintenance lamp 20 can be driven by the commutator 40 to rotate 180° to switch to Fig.21 In the second working position shown, the entire maintenance lamp 20 is stacked on the side of the bottom plate 12 close to the room, and the second light-emitting portion 201 is facing the room, and the first light-emitting portion 201 is away from the ground and arranged opposite to the bottom plate 12. At this time, the influence of the temperature of the air flow on the maintenance lamp 20 is weakened and can be ignored; when the air outlet 125 stops blowing warm air into the room, the maintenance lamp 20 can be driven by the commutator 40 to Fig.13 The position state shown can also be driven to Fig.21 The position status shown.

[0172] See also Figure 24-25The maintenance lamp 20 includes a lamp board 21 and a plurality of light-emitting bodies 22 laid on one side of the lamp board 21, the light-emitting portion 201 includes a plurality of light-emitting bodies 22 and a side of the lamp board 21 on which the light-emitting bodies 22 are provided, the maintenance lamp 20 also includes a backlight portion 202, the backlight portion 202 includes a side of the lamp board 21 away from the light-emitting bodies 22; the maintenance lamp 20 can be rotatably mounted on the fuselage 10 and can be switched between a working position and a docking position by rotating relative to the fuselage 10; the fuselage 10 includes a chassis 11 and a bottom plate 12 installed on the indoor side of the chassis 11, the bottom side 121 includes a side of the bottom plate 12 away from the chassis 11, and a rotating space 131 is provided in the chassis 11 for the maintenance lamp 20 to rotate therein, the rotating space 131 penetrates the bottom side 121 to form a light outlet 122, and the light outlet 122 can be a through hole opened in the bottom plate 12.

[0173] Specifically, the axis of rotation of the maintenance lamp 20 relative to the fuselage 10 is not perpendicular to the bottom side 121.

The axis of rotation of the maintenance lamp 20 relative to the body 10 is parallel to the bottom side 121 and the ceiling panel. The axis of rotation of the maintenance lamp 20 may be the output shaft axis of the commutator motor. When the maintenance lamp 20 is in the parked position, the light-emitting portion 201 faces away from the room, and the backlight portion 202 faces toward the room through the light outlet 122. When the maintenance lamp 20 is in the working position, the backlight portion 202 faces away from the room.

[0174] Figure 24-25 In the illustrated embodiment, the maintenance lamp 20 is always located in the rotating space 131. When the maintenance lamp 20 is in the working position, the light-emitting portion 201 faces the indoor room through the light outlet 122 and does not protrude from the bottom side 121. When the maintenance lamp 20 is in the docking position, the backlight portion 202 faces the indoor room through the light outlet 122 and does not protrude from the bottom side 121, and the light-emitting portion 201 is docked on the side of the bottom plate 12 away from the indoor room.

[0175] In other embodiments, when the maintenance lamp 20 is switched to the working position, the maintenance lamp 20 can extend from the rotation space 131 so that the light-emitting portion 201 protrudes from the bottom side 121 and extends into the room to shorten the distance between the light-emitting portion 201 and the human body, thereby increasing the human body's absorption rate of the energy of the maintenance light.

[0176] exist Figure 24-25On the basis of the shown embodiment, a shifter 30 can be further provided. The shifter 30 includes an output member 32 and a driver 31 connected to the output member 32. The output member 32 can be raised and lowered relative to the chassis 11 along a preset moving trajectory. The commutator 40 can be installed on the output member 32. The preset moving trajectory can be a vertical trajectory. The commutator 40 is responsible for the rotation of the maintenance lamp 20 in the rotating space 131 to adjust the orientation of the light-emitting part 201. The shifter 30 is used to drive the maintenance lamp 20 to rise and fall to adjust the distance between the light-emitting part 201 and the human body. The energy absorption of the maintenance light by the human body increases as the light-emitting part 201 moves downward.

[0177] See also Figure 22-23 The ceiling appliance 100 with maintenance function includes a commutator 40, which can be a commutation motor installed on the body 10. The maintenance lamp 20 includes a lamp board 21 and a plurality of light-emitting bodies 22. The plurality of light-emitting bodies 22 are laid on one side of the lamp board 21. The light-emitting part 201 includes the light-emitting body 22 and a side of the lamp board 21 on which the light-emitting body 22 is provided. The maintenance lamp 20 is rotatably installed on the body 10, and the axis of rotation of the maintenance lamp 20 is not perpendicular to the bottom side 121. The body 10 includes a chassis 11 and a bottom plate 12 installed on the side of the chassis 11 close to the indoor room. The bottom side 121 includes a side of the bottom plate 12 away from the chassis 11. A rotating space 131 is provided in the chassis 11 for the maintenance lamp 20 to rotate therein. The bottom side 121 is provided with a light outlet 122 connected to the rotating space 131. The light outlet 122 can be a through hole passing through both sides of the bottom plate 12.

[0178] Specifically, the axis of rotation of the maintenance lamp 20 relative to the fuselage 10 is parallel to the bottom side 121 and the ceiling plate, and the axis of rotation of the maintenance lamp 20 may be the axis of the output shaft of the commutation motor. Figure 24-25 The difference between the shown embodiments is that Figure 22-23 In the illustrated embodiment, a rotatable shield 50 is further provided on the body 10, and the axis of rotation of the shield 50 relative to the body 10 is not perpendicular to the bottom side 121 and the horizontal direction. When the maintenance lamp 20 is in the docked position, the shield 50 closes the light outlet 122. At this time, the shield 50 can prevent the water mist in the bathroom from invading the body 10 or contacting the maintenance lamp 20 through the light outlet 122. When the maintenance lamp 20 is in the working position, the shield 50 opens the light outlet 122 to allow the maintenance light to be projected into the room.

[0179] Further, Figure 24-25 In the illustrated embodiment, the axis of rotation of the maintenance lamp 20 relative to the fuselage 10 is located in the middle of the lamp board 21. The lamp board 21 includes two edges disposed opposite to each other. The two edges are approximately symmetrical about the axis of rotation of the maintenance lamp 20 relative to the fuselage 10. Figure 24-25 The embodiment shown, Figure 22-23The difference of the illustrated embodiment is that the distance from the axis of rotation of the maintenance light 20 relative to the fuselage 10 to the first edge is significantly smaller than the distance from the axis of rotation of the maintenance light 20 relative to the fuselage 10 to the second edge.

[0180] Optional, Fig. 22 and Fig.23 In the illustrated embodiment, the maintenance lamp 20 and the shielding member 50 rotate alternately relative to the body 10 to alternately rotate to a position where the light outlet 122 is closed. Fig. 22 In the parking position shown, the shield 50 closes the light outlet 122 and does not protrude from the bottom side 121, and the maintenance lamp 20 is parked on the side of the bottom plate 12 away from the room. Fig.23 In the working position shown, the maintenance lamp 20 occupies the light outlet 122, the light emitting portion 201 does not protrude from the bottom side 121, and the shielding member 50 rests on the side of the bottom plate 12 away from the room and the ground.

In this way, the bottom of the ceiling appliance 100 with maintenance function close to the human body is flat.

[0182] Figure 22-23 In the illustrated embodiment, the maintenance lamp 20 rotates at an angle of 90° relative to the fuselage 10, and the maintenance lamp 20 remains horizontal and vertical in the working position and the docked position, respectively. It can be understood that the maintenance lamp 20 rotates at an angle of 180° relative to the fuselage 10, so that the maintenance lamp 20 remains horizontal in both the working position and the docked position. In the working position, the light-emitting portion 201 faces the ground, and in the docked position, the backlight portion 202 faces the ground. The maintenance lamp 20 is now stacked on the bottom plate 12.
