[0033] This application provides an electrical device 100 equipped with a therapeutic function, which may be a heater equipped with a therapeutic function, a ventilation fan equipped with a therapeutic function, or a fresh air unit equipped with a therapeutic function. The electrical device 100 equipped with a therapeutic function of this application includes a main body 10, a nursing lamp 30 provided on the main body 10, and a heat dissipation structure 40 connected to the nursing lamp 30, wherein the nursing lamp 30 is used to realize a therapeutic function which includes one or more of the following: physical therapy / nursing care, beauty, skin care, and body care.

[0034] In addition to heating the room by blowing warm air into it using the air distribution device 20, the panel 12 is equipped with a care lamp 30 with beauty functions, and based on this, the panel 12 may be further equipped with a functional module to provide more auxiliary functions, the functional module including one or more of the following: lighting lamps, status indicator units and heating lamps.

[0035] The Nourishing Lamp 30 is used to generate light of special wavelengths such as blue light, red light, yellow light, and infrared light. These lights can directly or indirectly provide various cosmetic effects to the skin, such as brightening the skin tone, improving skin condition, making skin color lighter, and tightening pores. Therefore, the Nourishing Lamp 30 is also called a beauty lamp or therapeutic lamp. Blue light has antibacterial, anti-inflammatory, and sebum secretion suppression effects, which can alleviate problems such as acne and pimples, and also has some effect in improving problems such as acne scars, blemishes, and yellowish dullness of the skin. Red light has effects such as promoting collagen production and improving skin firmness, which can improve problems such as wrinkles and sagging. Infrared light not only promotes blood circulation but also has functions such as reducing body pain, resolving or reducing inflammation in the body, and suppressing body spasms.

[0036] The selectable wavelengths for blue light are 400-500nm, red light are 600-700nm, yellow light are 570-600nm, and infrared light are 850-1500nm. The specific wavelength depends on the different cosmetic function and treatment purpose.

[0037] Blue light has a wavelength of 400-470nm and has some effect in treating acne, inflammation, and allergies. Blue light reduces the occurrence of acne and inflammation by destroying the DNA structure of bacteria and killing them.

[0038] Red light has a wavelength of 630-700nm and has certain effects such as promoting the metabolism of skin cells, improving skin firmness and tightness, and improving skin pigmentation and blood circulation, thus brightening the skin tone. Red light can stimulate collagen production, reducing wrinkles and sagging.

[0039] Yellow light can not only promote blood circulation and lymphatic detoxification, but also improve the elasticity of capillaries, enhance the skin's immune function, reduce skin sensitivity, break down pigments, lighten blemishes, and tighten pores.

[0040] Figure 1 shows a partial structure of a heater with therapeutic functions after the air distribution device 20 has been omitted. The heater with therapeutic functions realizes the warm air heating function by the air distribution device 20, and the main body 10 includes a housing (not shown) and further includes a panel 12 that matches the housing.

[0041] Referring to Figure 1, the panel 12 includes a frame 121, a rear cover 122, and a lens 33, the frame 121 being used to house at least some of the components for mounting the care lamp 30 and having upward and downward openings, the lens 33 closing the opening on one side of the frame 121 and the rear cover 122 closing the opening on the other side of the frame 121.

[0042] Optionally, the lens 33 may be a part that is integrally molded with the frame 121.

[0043] The care lamp 30 is provided within the frame 121 of the panel 12, and referring to Figure 1, the care lamp 30 includes a plate-shaped circuit board 34 and a heat sink 35. The care lamp 30 is located on the lens 33 side, where the lens 33 forms the light-emitting portion 31 of the care lamp 30, and the heat sink 35 is located on the rear cover 122 side. At least a portion of the heat sink 35 is in contact with the surface of the circuit board 34, and the heat sink 35 is connected to the surface of the circuit board 34 via thermally conductive silicone grease, and the circuit board 34 forms the heat storage portion 32 of the care lamp 30.

[0044] The heat sink 35 is usually made of a metal material, such as aluminum, copper, and aluminum alloys. These materials have excellent thermal conductivity and can quickly absorb the heat generated in the care lamp 30, and quickly release the heat through surface heat dissipation, thereby maintaining the normal operation of the care lamp 30.

[0045] The material of the heat sink 35 may be ceramic or glass, as selectable.

[0046] Generally, the power and irradiation angle of the protective lamp 30 affect the range of light emission. When the power is low, the irradiation range is relatively small, and a person's face needs to be relatively close. This is not very convenient in practice. Therefore, the power of the protective lamp 30 needs to be increased. After increasing the power, the heat generated becomes relatively larger and is transferred to the circuit board 34 and the casing.

[0047] Therefore, a heat dissipation structure 40 is required for the care lamp 30 and the panel 12, the heat dissipation structure 40 includes at least a fluid drive unit 42 and further has a heat dissipation path, at least a portion of the care lamp 30 is located in the heat dissipation path, and the fluid drive unit drives a refrigerant to flow along the heat dissipation path through the care lamp 30 to absorb and carry away the heat from the care lamp 30.

[0048] Optionally, the fluid drive unit 42 includes an air drive unit 421, which may be a fan or another air blowing assembly. The heat dissipation structure 40 further includes an inlet that functions as an air intake 411 and an outlet that functions as an exhaust port 412, with a heat dissipation path formed between the air intake 411 and the exhaust port 412 for air to flow.

[0049] Optionally, the air-driven unit 421 is provided at the air intake 411 of the rear cover 122, and at least a portion of the protective lamp 30 is located in the heat dissipation path.

[0050] Selectively, the heat sink 35 of the care lamp 30 is located in the heat dissipation path. Upstream of the care lamp 30, a fluid drive unit 42 is provided, which outputs a fluidized refrigerant and transports the fluidized refrigerant into the heat dissipation path. As the refrigerant passes over the location of the heat sink 35, it carries away the heat generated in the care lamp 30 through the exhaust port 412.

[0051] Referring to Figures 1 and 2, in order to enhance the heat dissipation effect, the heat dissipation structure 40 further includes a heat dissipation member 44 provided between the rear cover 122 and the heat sink 35, the heat dissipation member 44 being located in the heat dissipation path and at least a portion of it in contact with the surface of the protection lamp 30, and the heat dissipation member 44 may specifically be in contact with the surface of the heat sink 35.

[0052] For the option of selection, the heat dissipation member 44 may be made of the same material as the heat sink 35, and specifically, it may be made of aluminum.

[0053] Referring to Figure 2, the heat dissipation member 44 includes a substrate 442 and fins 441. The substrate 442 is fixed to the surface of the heat sink 35, and multiple fins 441 are located on the substrate 442. Fin gaps 4411 are provided between adjacent fins 441, or between each fin 441, which are located in the heat dissipation path, and these fin gaps 4411 form a heat dissipation passage 443. The refrigerant can increase the heat dissipation area by passing through the heat dissipation passages 443 in the multiple fins 441, and is transferred from the circuit board 34 to the heat sink 35, improving heat dissipation efficiency by dissipating heat from the surface of the multiple fins 441.

[0054] The heat dissipation passage 443 can be selected to be straight, bent, arc-shaped, or wavy. Any of these shapes can increase the contact area with the airflow and enhance the heat dissipation effect.

[0055] The heat dissipation passage 443 is optionally provided extending in the direction of the heat dissipation path to reduce the flow resistance of the refrigerant, increase the flow velocity of the refrigerant, improve the heat transfer exchange efficiency, and thereby improve the heat dissipation efficiency.

[0056] Referring to Figures 1 and 3, the intake port 411 and exhaust port 412 are provided in the rear cover 122. When the rear cover 122 is provided in an elongated shape, the intake port 411 and exhaust port 412 are located at both ends of the rear cover 122 in the longitudinal direction.

[0057] Selectively, a heat dissipation chamber 41 is provided between the rear cover 122 and the protection lamp 30, that is, between the rear cover 122 and the heat sink 35, forming a heat dissipation path. Since the intake port 411 and exhaust port 412 communicate with the heat dissipation chamber 41, the heat dissipation member 44 is provided inside the heat dissipation chamber 41.

[0058] If the air-driven unit 421 is a fan, its impeller rotates to transport a flowing airflow into the heat dissipation path. By blowing air through the air-driven unit 421, heat is quickly removed, allowing the frame 121, heat sink 35, fins 441, and circuit board 34 to dissipate heat more quickly, thereby improving the stability of the placement of the high-power protective lamp 30. Additionally, by blowing air through the air-driven unit 421, the surface of the heat sink 35 can be kept dry, preventing corrosion problems caused by moisture.

[0059] Optionally, the rear cover 122 is further provided with a confluence passage 451, the confluence passage 451 and the heat dissipation chamber 41 are in communication with each other and are positioned perpendicular to each other, and the intake port 411 is located at the distal end of the confluence passage 451 away from the heat dissipation chamber 41.

[0060] Optionally, the rear cover 122 is further provided with a confluence passage 451 that communicates with the heat dissipation chamber 41, the confluence passage 451 and the heat dissipation chamber 41 are inclined relative to each other, and the air drive unit 421 is located either at the intake port 411 or within the confluence passage 451.

[0061] When the confluence passage 451 and the heat dissipation chamber 41 are in communication with each other and are positioned perpendicular to each other, the air drive unit 421 is located at the air intake port 411. The air drive unit 421 and the heat dissipation chamber 41 are spaced apart. The length of this space is determined according to the design air velocity of the air drive unit 421.

[0062] When the air drive unit 421 is close to the bottom wall on the side of the heat dissipation chamber 41 closest to the protective lamp 30, the blown air velocity is high, the resistance acting on the bottom wall of the heat dissipation chamber 41 is large, a vortex region is formed in the corner of the heat dissipation chamber 41, and the vortex region prevents the airflow from entering the heat dissipation chamber 41.

[0063] By adding the confluence passage 451, a certain distance is formed between the air drive unit 421 and the heat dissipation chamber 41. The airflow blown in by the air drive unit 421 must travel a certain distance before entering the heat dissipation chamber 41 or reaching the bottom wall of the heat dissipation chamber 41. The confluence passage 451 acts as a buffer passage, reducing the air velocity reaching the heat dissipation chamber 41. This significantly reduces the formation of vortex regions, thus avoiding resistance caused by vortex regions and increasing the intake air volume.

[0064] The fluid drive unit 42 may be a water source, and the refrigerant may be cooling water or a chemical coolant.

[0065] Referring to Figures 4 to 10, the electrical equipment 100 with therapeutic functions may be a heater with therapeutic functions, and the main body 10 includes a housing 11, a spiral casing 14, a panel 12, a wind collector plate 13, and a movable partition plate 18, the nursing lamp 30 is provided on the panel 12, and the air distribution device 20 includes a centrifugal fan provided inside the housing 11.

[0066] Selectively, the spiral casing 14 is provided inside the housing 11, and the spiral casing 14 has a spiral passage 141, the panel 12 is further provided with an air inlet 123 which communicates with the spiral passage 141, and the air collecting plate 13 is provided between the spiral casing 14 and the panel 12, and there is a cavity between the panel 12 and the air collecting plate 13, which forms a heat dissipation chamber 41 of the heat dissipation structure 40.

[0067] The heat dissipation structure 40 further includes heat dissipation holes 133 provided in the air collecting plate 13, and the air in the spiral passage 141 is suitable for entering the cavity between the panel 12 and the air collecting plate 13 through the heat dissipation holes 133, and the movable partition plate 18 is suitable for opening and closing the heat dissipation holes 133.

[0068] Optionally, the centrifugal fan includes a centrifugal impeller 201, and the spiral casing 14 is a casing formed on the circumferential side of the centrifugal fan, with a spiral passage 141 formed between the spiral casing 14 and one bottom surface of the housing 11, and the air collecting plate 13 and the spiral casing 14 are provided separately, with the end of the sealed spiral passage 141 furthest from the bottom surface of the housing 11 forming an air passage through which gas flows.

[0069] The air collection plate 13 may be integrally molded with the spiral casing 14, or the air collection plate 13 may be part of the centrifugal fan.

[0070] Referring to Figure 4, the panel 12 is provided to cover the upper end of the spiral casing 14, and the air collecting plate 13 is provided between the panel 12 and the spiral casing 14. The air collecting plate 13 can isolate the panel 12 and the spiral casing 14, and the air collecting plate 13 and the panel 12 form a cavity surrounding it. At least three side surfaces of the circumferential side of the panel 12 are provided with air inlets 123.

[0071] Referring to Figure 6, air inlets 123 are provided on the lower side and both sides of the panel 12, and the spiral passage 141 is in communication with the air inlets 123, so that air enters the spiral passage 141 through the air inlets 123. Since the air collecting plate 13 is provided with heat dissipation holes 133, the air in the spiral passage 141 enters the cavity through the heat dissipation holes 133, the back surface of the protection lamp 30 is the heat storage part 32 of the protection lamp 30, and the back surface of the protection lamp 30 is located in the cavity, so that the flowing air that enters the cavity carries away some of the heat generated in the protection lamp 30, allowing the protection lamp 30 to dissipate heat.

[0072] The movable partition plate 18 is rotatably provided within the spiral passage 141 and is located at the lower end of the heat dissipation hole 133. The upper end surface of the movable partition plate 18 can be in close contact with the lower end of the heat dissipation hole 133, thereby closing the heat dissipation hole 133 and preventing air within the spiral passage 141 from entering the cavity.

[0073] Selectively, the movable partition plate 18 can be rotated clockwise to disengage contact with the heat dissipation vent 133, opening the heat dissipation vent 133 and thereby allowing air in the swirling passage 141 to enter the cavity through the heat dissipation vent 133. The care lamp 30 is electrically connected to a switch, and the movable partition plate 18 is also electrically connected to a switch.

[0074] When the switch is turned on, the care lamp 30 lights up, and the movable partition plate 18 rotates clockwise, allowing air in the spiral passage 141 to enter the cavity and dissipate heat from the care lamp 30. When the switch is turned off, the care lamp 30 turns off, and the movable partition plate 18 rotates counterclockwise, causing the upper end surface of the movable partition plate 18 to come into close contact with the lower end of the heat dissipation hole 133, blocking the heat dissipation hole 133 and preventing air from entering the cavity.

[0075] The movable partition plate 18 may be optionally slidably mounted on the air collection plate 13. When the switch is turned on, the care lamp 30 lights up, and the movable partition plate 18 slides to open the heat dissipation holes 133, allowing air in the swirling passage 141 to enter the cavity and dissipate heat from the care lamp 30. When the switch is turned off, the care lamp 30 turns off, and the movable partition plate 18 slides to close the heat dissipation holes 133, blocking the heat dissipation holes 133 and preventing air from entering the cavity.

[0076] Selectively, the spiral passage 141 has an air duct 24, the movable partition plate 18 is provided within the air duct 24, and the heat dissipation holes 133 are provided corresponding to the movable partition plate 18. Referring to Figures 5 and 7, the left side of the spiral passage 141 is the air duct 24, the movable partition plate 18 is provided within the air duct 24, and the heat dissipation holes 133 are provided corresponding to the movable partition plate 18.

[0077] Optionally, the panel 12 is further provided with an air outlet 124, and a heating device 50 is further provided within the air duct 24, the heating device 50 including a heating structure 51 and an output pipe 52, the open end of the heating structure 51 communicating with the air duct 24, the output end of the heating structure 51 communicating with one end of the output pipe 52, the other end of the output pipe 52 connected to the air outlet 124 of the panel 12, and a movable partition plate 18 in the air duct 24 is provided in front of the open end of the heating structure 51.

[0078] As shown in Figures 4 and 5, a heating device 50 is provided in the air duct 24, and the heating device 50 includes a heating structure 51 for heating air and an output pipe 52 for discharging the heated air. The open end of the heating structure 51 is in communication with the air duct 24, and the air in the air duct 24 can enter the heating structure 51 and be heated. The output pipe 52 is provided at the rear end of the heating structure 51, and one end of the output pipe 52 is connected to the output end of the heating structure 51, and the heated air enters the output pipe 52 from the output end of the heating structure 51, and the other end of the output pipe 52 is connected to the air outlet 124 of the panel 12, and the heated air can be discharged from the air outlet 124.

[0079] Referring to Figure 6, the air outlet 124 is located on the upper side of the panel 12. As shown in Figures 5 and 7, the movable partition plate 18 is located to the right of the opening end of the heating structure 51.

[0080] The air collection plate 13 is further provided with air outlets 135, which are provided in accordance with the output pipe 52, and the other end of the output pipe 52 passes through the air outlets 135 and is connected to the air outlet 124.

[0081] Selectively, the heating structure 51 is a PTC heater.

[0082] When using the heater, you can normally turn on the fan mode with the safety lamp 30 turned on, and in ventilation mode, you can turn off the safety lamp 30, or of course, use the fan mode with the safety lamp 30 turned off.

[0083] Referring to Figures 8 and 9, after the safety lamp 30 is turned on, the movable partition plate 18 rotates clockwise to release contact with the heat dissipation holes 133 and simultaneously turns on the fan mode. Air enters the swirling passage 141 through the air inlet 123 and then enters the fan duct 24. Some of the air enters the cavity through the heat dissipation holes 133 to dissipate heat from the safety lamp 30, and the remaining air enters the heating structure 51 and is heated. After the safety lamp 30 is turned off, the movable partition plate 18 rotates counterclockwise to make close contact with the heat dissipation holes 133 and close them. At this time, all the air in the fan duct 24 enters the heating structure 51 and is heated.

The limiting structure 61 is fixed to the inner wall of the spiral passage 141. When the movable partition plate 18 rotates clockwise, the limiting structure 61 restricts the movable partition plate 18, preventing a large amount of air from entering the cavity due to an excessively large opening of the movable partition plate 18, which would reduce the amount of heated air and affect the airflow function.

[0086] Selectively, the limiting structure 61 is a protruding structure.

[0087] Selectively, the opening height of the movable partition plate 18 is h ≤ H / 6, where H is the height of the spiral passage 141.

[0088] As shown in Figure 10, the opening height of the movable partition plate 18 is set to h ≤ H / 6 to avoid excessive airflow loss, which would affect the airflow or airflow thermal performance.

[0089] Optionally, a power structure 62 is provided on the side wall of the spiral casing 14, and the output end of the power structure 62 is connected to the movable partition plate 18.

The output end of the power structure 62 is connected to a transmission shaft 63, which is rotatably mounted within the air duct 24. A through hole is provided at the upper end of the movable partition plate 18, which is fixed to the transmission shaft 63 via the through hole. The power structure 62 is electrically connected to a switch. When the switch is turned on, the output end of the power structure 62 rotates, causing the transmission shaft 63 to rotate clockwise, which in turn rotates the movable partition plate 18 clockwise, releasing contact between the movable partition plate 18 and the heat dissipation holes 133. When the switch is turned off, the output end of the power structure 62 rotates, causing the transmission shaft 63 to rotate counterclockwise, which in turn rotates the movable partition plate 18 counterclockwise, closing the heat dissipation holes 133 to the movable partition plate 18.

[0092] The power structure 62 is selectable to be a stepping motor.

[0093] Selectively, one side of the centrifugal impeller 201 is an air supply passage 24, and the other side of the centrifugal impeller 201 is a ventilation passage 23. The air collecting plate 13 is provided with ventilation holes 134, which are provided corresponding to the air intake of the centrifugal impeller 201, and the ventilation holes 134 are connected to the air inlet 123.

The air collecting plate 13 is provided with ventilation holes 134, which are provided corresponding to the air intake port of the centrifugal impeller 201, and the ventilation holes 134 are connected to the air inlet 123, so that air passes through the air inlet 123, the ventilation holes 134 and the air intake port of the centrifugal impeller 201 in order before entering the spiral passage 141.

[0095] In blower mode, the centrifugal impeller 201 rotates clockwise, accelerating the air and blowing it into the blower air passage 24. In ventilation mode, the centrifugal impeller 201 rotates counterclockwise, blowing the air into the ventilation air passage 23.

[0096] The care lamp 30 can be selected from a planar lamp or an LED lamp having a special wavelength, for example, the selectable wavelengths of the care lamp 30 include a blue light wavelength of 400-500 nm, a red light wavelength of 600-700 nm, and a yellow light wavelength of 570-600 nm.

[0097] In some embodiments, the spiral passage 141 includes an air supply passage 24 and a ventilation passage 23, and there are at least two movable partition plates 18, with at least one movable partition plate 18 in the air supply passage 24 and at least one movable partition plate 18 in the ventilation passage 23, and the heat dissipation holes 133 are provided corresponding to the movable partition plates 18.

The panel 12 is provided on the side of the main body that is relatively closer to the interior of the room, that is, the main body is provided on the side of the panel 12 that is relatively far from the interior of the room. The housing 11 is a hollow structure having a cavity 111, and is installed in the area between the ceiling of the room and the suspended ceiling panel, and is supported by the suspended ceiling panel, and an air distribution device 20 for distributing air is provided in the cavity 111.

[0100] The spacing section 17 includes a wind-collecting plate 13 attached to the side of the housing 11 closer to the ground. The side of the wind-collecting plate 13 away from the ground, together with the housing 11, forms a structure surrounding the cavity 111. The panel 12 and the safety lamp 30 are provided on the other side of the wind-collecting plate 13, i.e., the panel 12 and the safety lamp 30 are provided on the side of the wind-collecting plate 13 closer to the ground. The panel 12 may be connected to the housing 11, or it may be connected to a suspended ceiling panel, a keel, a support structure that supports the housing 11, etc.

[0101] The main body 10 has a roughly rectangular parallelepiped structure, and the panel 12 has a roughly rectangular plate structure.

[0102] Optionally, the enclosure 15 is provided with a mounting space 152 for housing an air-driven unit 421, the mounting space 152 having an air outlet 153 leading to the heat storage unit 32 of the care lamp 30, the heat dissipation structure 40 includes the air-driven unit 421, and at least a portion of the air-driven unit 421 is provided within the mounting space 152.

[0103] As the air drive unit 421 operates and drives air to form a heat dissipation airflow, the mounting space 152 further functions as a location for forming the heat dissipation airflow, and the air drive unit 421 is used to drive air to flow out of the mounting space 152 through the air outlet 153 and further to form a heat dissipation airflow that flows to the heat storage unit 32.

[0104] Optionally, the side of the air collector 13 away from the housing 11 may face the interior wall, in which case the panel 12 is provided on the side of the air collector 13 that faces the interior and away from the housing 11, and the panel 12 does not need to face the ground, as long as the mounting space 152 can communicate with the cavity 111 and the mounting space 152 has an air outlet 153 that leads to the panel 12.

[0105] Selectively, the mounting space 152 is adjacent to the side of the air collection plate 13 that is away from the interior, the mounting space 152 penetrates both the side of the air collection plate 13 that is away from the interior and the other side that is facing the interior, and the air outlet 153 opens toward the panel 12, thus reducing the flow path and resistance of the heat dissipation airflow from the air outlet 153 toward the panel 12.

[0106] Selectively, the air drive unit 421 may be a fan, a blower, or any other type of device capable of disturbing and accelerating air. The air drive unit 421 is used to drive air to form a heat dissipation airflow, which is used to dissipate heat and cool the care lamp 30 and the panel 12, thereby improving the lifespan and operational reliability of the panel 12, the care lamp 30 provided on the panel 12, and the functional modules provided on the panel 12.

[0107] Referring to Figures 11-12 and 13-14, the panel 12 is positioned at a predetermined location on the side of the air collection plate 13 closest to the ground, and after being matched and combined with the housing 11, the housing 11, the air collection plate 13, and the panel 12 are stacked in order.

[0108] Selectively, the housing 11 is positioned in a predetermined location within the suspended ceiling space between the room's ceiling and the suspended ceiling panel. After the housing 11 is supported by the suspended ceiling panel, the housing 11, the air collection plate 13, and the panel 12 are stacked vertically in sequence, with both the air collection plate 13 and the panel 12 extending horizontally parallel to the suspended ceiling panel.

[0109] Referring to Figures 12 and 14, the cavity 111 and panel 12 of the housing 11 are located on either side of the air collection plate 13, the mounting space 152 penetrates both sides of the air collection plate 13, and the cavity 111 communicates with the area of ​​the air collection plate 13 away from the housing 11 via the mounting space 152.

[0110] As a result, when the air drive unit 421 operates, the air in the cavity 111 is drawn into the air drive unit 421 and flows through the mounting space 152, then flows out of the mounting space 152 through the air outlet 153, the air flowing out from the air outlet 153 forms a heat dissipation airflow, and finally the heat dissipation airflow flows to the heat storage section 32 of the care lamp 30 and carries away the heat from the care lamp 30.

[0111] Optionally, the enclosure 15 includes a hollow boss 151 which protrudes from the panel 12 of the air collection plate 13 and away from the ground and has a hollow passage which forms a mounting space 152, and at least a portion of the air drive unit 421 is located within the hollow passage and is enclosed and fitted within the side walls of the hollow boss 151.

[0112] Referring to Figures 12 and 14, the air-driven unit 421 includes an axial fan located in a hollow passage and surrounded by a hollow boss 151, the ends of the axial fan that are away from the panel 12 and the ground and the ends of the hollow boss 151 that are away from the panel 12 and the ground are on the same plane as each other.

[0113] Selectively, the hollow boss 151 is integrally molded with the air collection plate 13, the outer wall of the axial fan and the inner wall surface of the hollow passage have the same shape and dimensions, and are fitted together to form a profile fit, thereby fixing the position and orientation of the axial fan relative to the enclosure 15 and the air collection plate 13.

[0114] As selectable, referring to Figures 11 and 13, the hollow boss 151 and the air drive unit 421 provided in the hollow passage are both located in the cavity 111 and surrounded by the housing 11, the mounting space 152 is in communication with the cavity 111, and a heat dissipation intake port 112 is further opened in the housing 11, the heat dissipation intake port 112 is in communication with the outside of the housing 11 and the cavity 111.

[0115] As a result, after the housing 11 is positioned in a predetermined location within the suspended ceiling space, the suspended ceiling space is connected to the cavity 111 via the heat dissipation intake 112, and further connected to the mounting space 152 and the air outlet 153. Air within the suspended ceiling space is drawn into the cavity 111 by the air drive unit 421, then flows through the mounting space 152, and finally flows out through the air outlet 153 to the heat storage unit 32.

[0116] Optionally, the hollow boss 151 may be provided in parallel with the housing 11 on the side of the air collection plate 13 away from the panel 12, in which case the hollow boss 151 is located outside the housing 11 and the hollow passage communicates with the outside of the housing 11. The enclosure 15 is not limited to the hollow boss 151, and the enclosure 15 may be other structures provided inside or outside the housing 11.

[0117] Referring to Figures 11, 13, and 15, the main body 10 further includes a grille 113 formed in the housing 11, a heat dissipation intake 112 is opened in the grille 113, and the grille 113 includes a drain surface 1131 provided on the opposite side from the cavity 111, and after the housing 11 is placed in the suspended ceiling space, the drain surface 1131 is provided at an inclination with respect to the vertical and faces the ground.

[0118] Optionally, the grille 113 is integrally molded with the housing 11, each grille 113 extends horizontally, the side wall of the housing 11 is located between the top wall of the housing 11 and the air collector 13, the top wall of the housing 11 is the side of the housing 11 that is far from the ground and close to the ceiling of the room, and the air collector 13 and the top wall of the housing 11 are spaced apart and facing each other.

[0119] As a result, when mist droplets in the suspended ceiling space come into contact with the grille 113, they flow along the drain surface 1131 toward the ground, and if a water leak occurs on an upper floor, the liquid leaking from the ceiling of the room flows along the drain surface 1131 toward the ground, so that the grille 113 can provide waterproof protection to the air-driven unit 421 and the internal devices of the housing 11.

[0120] Referring to Figures 11-12 and 13-14, the heat dissipation structure 40 further includes a heat dissipation member 44 that is heat conductably connected to the care lamp 30, and the air outlet 153 leads to the heat dissipation member 44.

[0121] The heat dissipation member 44 and the care lamp 30 form a heat-conductive connection through direct contact, bonding with a thermally conductive adhesive, or connection via a heat transfer element, thereby conducting the heat generated when the care lamp 30 is operating to the heat dissipation member 44. After the air drive unit 421 operates, the heat dissipation airflow flows over the heat dissipation member 44, forming convective heat transfer with the heat dissipation member 44, thereby carrying away the heat from the heat dissipation member 44.

[0122] Optionally, the main body 10 further includes a lid-fitting member 16 connected to the panel 12, the lid-fitting member 16 and the panel 12 forming a surrounding heat dissipation chamber 41, the lid-fitting member 16 having a butt joint port 162 that connects the heat dissipation chamber 41 and the air outlet 153, and the heat dissipation member 44 is provided inside the heat dissipation chamber 41. Therefore, the heat dissipation airflow that leaves the housing 11 from the air outlet 153 can be concentrated on blowing the heat dissipation member 44 and is less likely to diffuse into areas outside the heat dissipation chamber 41, thereby improving the utilization rate of the heat dissipation airflow.

[0123] Referring to Figures 12 and 14, the heat dissipation member 44 includes a plurality of fins 441 arranged in parallel and spaced apart within the heat dissipation chamber 41, the fins 441 being heat conductably connected to the side of the heat storage unit 32 away from the room and the ground, that is, the fins 441 and the care lamp 30 are provided on both sides facing the back of the panel 12, the heat dissipation member 44, the heat storage unit 32 of the care lamp 30 and the light-emitting unit 31 of the care lamp 30 are stacked in order, a heat dissipation gap is formed between any two adjacent fins 441, which is connected to the air outlet 153 and into which a heat dissipation airflow flows, the lid fitting member 16 is interposed between the air collecting plate 13 and the panel 12, and covers the side of the panel 12 away from the room and the ground, thereby forming the heat dissipation chamber 41 located between the air collecting plate 13 and the panel 12, the mounting space 152 is located on the side of the heat dissipation chamber 41 far from the panel 12.

[0124] Selectively, each fin 441 extends from the first end of panel 12 to the second end of panel 12, and panel 12 is rectangular in shape, with the first and second ends being the two ends along the length of panel 12, respectively.

[0125] Optionally, the mounting space 152 includes a hollow passage formed in the hollow boss 151, the direction of extension of the hollow passage being the same as the stacking direction of the three components: the air collection plate 13, the lid fitting member 16, and the panel 12; the hollow passage penetrates both sides of the air collection plate 13, connecting the heat dissipation chamber 41 and the cavity 111; the opening at the end of the hollow passage closest to the panel 12 forms an air outlet 153 that opens toward the heat dissipation member 44 and the heat storage section 32; the spacing section 17 further includes a hollow flange 171, which protrudes toward the panel 12 and the interior of the air collection plate 13 away from the housing 11; the lid fitting member 16 includes a butt joint 161 through which the butt joint opening 162 is formed; and the air outlet 153 communicates with the hollow portion of the hollow flange 171.

[0126] Selectively, one of the hollow flange 171 and the butt joint 161 is fitted onto the other and interlocked with each other, thereby establishing a state of interconnection between the mounting space 152, the air inlet 153, the hollow section of the hollow flange 171, the butt joint 162, and the heat dissipation chamber 41, and the heat dissipation airflow flowing out from the air inlet 153 is less likely to leak to the outside.

[0127] Referring to Figure 13, the lid fitting member 16 is further provided with a heat dissipation exhaust port 114. After the heat dissipation airflow absorbs heat from the heat dissipation member 44, it flows out of the heat dissipation chamber 41 through the heat dissipation exhaust port 114. The heat dissipation exhaust port 114 may also lead directly to the outside of the main body 10, thereby discharging the heat dissipation airflow after heat absorption into the suspended ceiling space. Of course, it may also lead into the housing 11, and the heat dissipation airflow after heat absorption is discharged outdoors or indoors using the air distribution device 20 inside the housing 11.

[0128] Alternatively, the housing 11 may be configured without a heat dissipation intake 112, in which case the air for forming the heat dissipation airflow may be provided by the housing 11, with some of the fresh air from outside entering the cavity 111 of the housing 11, then entering the mounting space 152, being driven and accelerated by the air drive unit 421, and then being blown out from the air outlet 153 to form the heat dissipation airflow. Alternatively, the housing 11 may draw in indoor air through an air collection port opened in the air collection plate 13, with some of the drawn-in indoor air entering the mounting space 152, being driven and accelerated by the air drive unit 421 to form the heat dissipation airflow.

[0129] Optionally, the hollow boss 151 may be omitted, and the enclosure 15 is formed of a plate or housing that forms the housing 11, and the housing 11 and the air collecting plate 13 surround the cavity 111 of the housing 11, with a portion of the cavity 111 forming a mounting space 152 for installing the air drive unit 421, and the remaining portion of the cavity 111 being used to house the air distribution device 20. The air collecting plate 13 has air outlets 153 that connect both sides of the air collecting plate 13, with the openings of the air outlets 153 facing the heat storage unit 32, and only a portion of the air drive unit 421 may be provided in the cavity 111.

[0130] Conventional heaters have the problem of an unreasonable weight distribution. Because the heat dissipation airflow generating device for generating heat dissipation airflow is integrated into the panel 12, the center of gravity of the entire structure formed by the panel 12 and the heat dissipation airflow generating device differs from the center of gravity of the panel 12 itself. This makes the panel 12 prone to tilting and shifting when installation staff lift and install it, and further increases the risk of the heat dissipation airflow generating device colliding with and damaging structures such as suspended ceiling panels and keels.

[0131] The electrical equipment 100 with therapeutic functions shown in Figures 11 to 15 integrates the air drive unit 421 into the housing 11 rather than the panel 12. This makes it less likely for the panel 12 to tilt and shift when installation staff lift and install it, eliminating the risk of collision damage due to instability of the air drive unit 421 and the panel 12 itself.

[0132] Furthermore, the air drive unit 421 can not only be integrated into the housing 11 but also be protected by the enclosure 15, which can isolate structures that could cause collision damage to the air drive unit 421. For example, when transporting the housing 11 into a suspended ceiling space, structures such as suspended ceiling panels and keels can be prevented from colliding with the air drive unit 421. Based on this, the housing 11 surrounds and shields the air drive unit 421 with the enclosure 15, thereby reducing the accumulation of mist in the suspended ceiling space mixed with dust and debris on the surface of the air drive unit 421, and delaying erosive damage to the air drive unit 421 caused by a mixture of mist, dust, and debris.

[0133] The electrical equipment 100 with therapeutic functions shown in Figures 16 to 18 is also a heater with therapeutic functions, and the main body 10 includes a housing 11 and a panel 12 provided on the side of the housing 11 that is relatively close to the room and the ground, the housing 11 may be installed in an opening in the suspended ceiling of the bathroom, the panel 12 is provided facing the user, the nursing lamp 30 is provided on the panel 12, the panel 12 has a frame 121 provided on its periphery, the frame 121 surrounds the periphery of the nursing lamp 30.

[0134] The panel 12 is substantially flat, and after the housing 11 is attached, the panel 12 is parallel to the horizontal direction.

[0135] The enclosure 11 is equipped with an air distribution device 20 for blowing warm air, heated air, or ambient temperature air into the room, and the heat dissipation structure 40 is connected to the care lamp 30 and is used to absorb the heat generated in the care lamp 30, and can carry away this heat from the care lamp 30.

[0136] Referring to Figure 16, the heat dissipation structure 40 includes a heat dissipation air passage 43 provided on the panel 12 and connected to the care lamp 30, the heat dissipation air passage 43 having a first air outlet 431 and a second air outlet 432 that are in communication with each other.

[0137] Taking the example that the electrical appliance 100 with therapeutic functions is a bathroom heater with therapeutic functions, one of the first air outlet 431 and the second air outlet 432 forms an air intake 411 for drawing in gas, and the other forms an exhaust port 412 for discharging gas. The gas enters the heat dissipation air passage 43 through the air intake 411 and forms a heat dissipation airflow. As the heat dissipation airflow flows through the heat storage section 32 of the care lamp 30, the heat from the care lamp 30 is conducted to the heat dissipation air passage 43 and absorbed into the heat dissipation airflow. The airflow after heat absorption continues to flow and is finally discharged from the exhaust port 412.

[0138] The cooling air passage 43 is optionally located on the side of the panel 12 that is relatively far from the ground and relatively close to the housing 11.

[0139] Referring to Figures 17 and 18, the heat dissipation structure 40 further includes a heat dissipation member 44, the heat dissipation member 44 includes fins 441, the fins 441 are arranged in parallel and spaced apart on the side of the panel 12 far from the ground, the fins 441 are located in a heat dissipation air passage 43, or the gaps between the fins 441 form a heat dissipation air passage 43, the side of the care lamp 30 far from the room is heat conductably connected to the fins 441, and the side of the care lamp 30 far from the room forms a heat storage section 32. First air inlets 431 and second air inlets 432 for forming an air intake 411 and an exhaust 412 are provided at both ends of the fins 441, respectively.

[0140] Referring to Figures 17 and 18, the gap between any two adjacent fins 441 is abbreviated as the fin gap 4411, and the opposing side walls of the two adjacent fins 441 form part of the inner wall of the heat dissipation air passage 43. Heat generated in the care lamp 30 is absorbed by the fins 441, and the airflow flows through the fin gap 4411, where it absorbs heat from the fins 441. The airflow is then discharged through the exhaust port 412 into the heat dissipation air passage 43, where fresh air continuously enters the air gap and continuously absorbs heat. The care lamp 30 is cooled by repeating the above process.

[0141] The use of fins 441 is optional, and the heat dissipation air passage 43 may be obtained by other means, for example, a structure having a pipe or cavity may be used as the heat dissipation air passage 43.

[0142] Referring to Figures 16 and 17, the heat dissipation structure 40 further includes an air drive unit 421 provided at the air intake 411, and the air drive unit 421 may be a fan. When the air drive unit 421 is in operation, it increases the air volume and velocity entering the heat dissipation air passage 43, provides thrust to the airflow entering the heat dissipation air passage 43, and can move the airflow to the exhaust port 412 faster. As the airflow velocity in the heat dissipation air passage 43 increases, more heat is absorbed and carried by the airflow, and the cooling efficiency increases.

[0143] Selectively, the inner wall of the heat dissipation air passage 43 and the opening edge of the intake port 411 are transitionally connected via a curved surface. Taking the embodiment shown in Figures 16 and 17 as an example, if the opening direction of the intake port 411 is away from the panel 12, and the mounting space is limited, the intake port 411 opened in the direction away from the panel 12 can be made larger, which is advantageous for improving the intake volume.

[0144] The air distribution device 20 includes at least a first fan 21, referring to Figures 16-17, which may be a centrifugal fan located within the housing 11 and on the side of the panel 12 that is relatively far from the interior and the ground. If the first fan 21 is a centrifugal fan, the center 2011 of the impeller of the first fan 21 is also called the center 211 of the first impeller, and the center 211 of the first impeller is located opposite the opening of the exhaust port 412.

[0145] In other words, when the first fan 21 operates, the airflow in the heat dissipation air passage 43 is discharged from the exhaust port 412 and then blown directly out to the center 211 of the first impeller. The heat-absorbing airflow discharged from the exhaust port 412 enters the first fan 21 directly and is finally discharged from the exhaust port of the spiral casing of the first fan 21.

[0146] The first fan 21 may be a centrifugal fan including a centrifugal impeller 201, which includes a rotating disk and a plurality of blades attached to the rotating disk, the center of the impeller 2011 being the axis of the rotating disk, and the plurality of blades being spaced apart in the circumferential direction of the rotating disk around the center of the impeller 2011. The rotating disk has pores that allow air to enter, and air gaps are formed between the blades. The airflow is discharged from the exhaust port 412, enters the centrifugal impeller 201 through the pores, and is then discharged through the air gaps between the blades.

[0147] When the first fan 21 is operating, a low-pressure region is formed near the center 2011 of the impeller, and the pressure within this region is significantly lower than the ambient pressure and significantly lower than the pressure around the outer periphery of the first fan 21.

[0148] The fact that the opening of the exhaust port 412 is positioned opposite the center 2011 of the impeller of the first fan 21 means that the orientation of the opening of the exhaust port 412 places the exhaust port 412 and the area around it within the low-pressure region formed by the first fan 21. On the other hand, the air pressure at the intake port 411 and the area around it is still at or above ambient pressure, which may result in a pressure difference being formed between the intake port 411 and the exhaust port 412, creating a pressure drop in the heat dissipation air passage 43.

[0149] Due to the effects of the pressure difference and pressure drop, the gas that enters the heat dissipation air passage 43 no longer maintains a static steady state and spontaneously flows away from the intake port 411 along the heat dissipation air passage 43 to the exhaust port 412, forming a heat dissipation airflow. In other words, the generation of airflow for cooling the protection lamp 30 no longer depends on the air drive unit 421, and even without the air drive unit 421, a heat dissipation airflow can be formed using the first fan 21.

[0150] Compared to the air-driven unit 421 blowing air into the heat-dissipating air passage 43, the heat-dissipating airflow formed by the first fan 21 has a stronger airflow force and a higher wind speed.

[0151] Based on the operating characteristics of the first fan 21, the airflow discharged from the heat dissipation air passage 43 through the exhaust port 412 is ultimately absorbed and taken in by the first fan 21. In other words, the first fan 21 can not only facilitate the rapid flow of gas in the heat dissipation air passage 43 to form a heat dissipation airflow, but can also expel the airflow that has absorbed the heat from the protective lamp 30 from the heat dissipation air passage 43 in a timely manner, thereby emptying the heat dissipation air passage 43. This reduces the resistance to new air entering the heat dissipation air passage 43 and increases the total amount of gas entering the heat dissipation air passage 43.

[0152] The first fan 21 and the air drive unit 421 may be provided simultaneously as an option, and the first fan 21 and the air drive unit 421 can work together to significantly improve the airflow velocity and wind force in the heat dissipation air passage 43, thereby significantly improving the ability of the heat dissipation airflow to absorb and carry away the heat from the protection lamp 30.

[0153] Alternatively, the air drive unit 421 may be removed, and the protection lamp 30 may be cooled by dissipating heat using only the first fan 21.

[0154] Referring to Figures 16 and 17, the first fan 21 and the heat dissipation air passage 43 are located on the same side of the panel 12, that is, both are located on the side of the panel 12 that is relatively far from the ground. After the enclosure 11 is mounted on the suspended ceiling, the first fan 21 is located on the side of the suspended ceiling that is relatively far from the ground and is not visible to users below the panel 12.

[0155] The first fan 21, the heat dissipation air passage 43, the safety lamp 30, and the panel 12 are optionally arranged in a stacked manner, and after the housing 11 is attached to the suspended ceiling, the first fan 21, the heat dissipation air passage 43, the safety lamp 30, and the panel 12 are arranged in a vertical direction close to the ground.

[0156] Referring to Figures 16 and 17, the centerline of the opening of the exhaust port 412 and the center 2011 of the impeller of the centrifugal impeller 201 of the first fan 21 are arranged parallel to each other, and the center 2011 of the centrifugal impeller 201 of the first fan 21 is the center 211 of the first impeller shown in Figures 16 and 17. The center 211 of the first impeller extends into the opening of the exhaust port 412.

[0157] The centerline of the opening of the exhaust port 412 is a single imaginary straight line, which passes through the geometric center of the opening of the exhaust port 412, and the direction of extension of this line is the same as the direction of the instantaneous velocity of the airflow flowing out of the exhaust port 412.

[0158] Refer to Figures 16 and 17 as selectable, the opening direction of the exhaust port 412 is away from the panel 12, and after the housing 11 is mounted on the suspended ceiling of the bathroom, the exhaust port 412 is opened vertically upward, the center 211 of the first impeller extends vertically, and in this case the opening centerline of the exhaust port 412 is a vertically extending straight line. The opening shape of the exhaust port 412 is not limited and may be rectangular, square, or other shapes.

[0159] If we define a plane perpendicular to the center 211 of the first impeller as the airflow cross plane, then the point obtained by orthogonally projecting the center 211 of the first impeller onto the airflow cross plane lies within the figure obtained by orthogonally projecting the exhaust port 412 onto the airflow cross plane. As a result, more of the airflow discharged from the exhaust port 412 can be blown out to the centrifugal impeller 201, absorbed by the centrifugal impeller 201, and taken in.

[0160] Optionally, the heat dissipation structure 40 further includes an exhaust member 46 provided in the heat dissipation air passage 43, the exhaust member 46 being provided with an exhaust passage 461, one end of which communicates with the fin gap 4411 and the heat dissipation air passage 43, and the other end forming an exhaust port 412. Referring to Figure 16, the exhaust passage 461 includes an upstream segment extending along the panel 12 and the protection lamp 30, and further includes a downstream segment extending toward the housing 11 and the first fan 21 in a direction away from the panel 12 and the protection lamp 30.

[0161] The upstream segment is connected to the fin gap 4411 and the heat dissipation air passage 43, and the end of the downstream segment forms an exhaust port 412. Since the inner walls of the upstream segment and the downstream segment transition with curved surfaces, the inner wall of the exhaust passage 461 and the opening edge of the exhaust port 412 also transition with curved surfaces, thereby reducing the flow resistance of the heat dissipation airflow and thereby reducing the loss of kinetic energy of the heat dissipation airflow.

[0162] Optionally, the heat dissipation structure 40 further includes an air guide 462 provided in the heat dissipation air passage 43, the air guide 462 protruding outward along the exhaust direction of the exhaust port 412, extending toward and approaching the first fan 21, and the inner wall of the exhaust passage 461 and the opening edge of the exhaust port 412 transition via the air guide 462.

[0163] The exhaust member 46 and the air guide section 462 provide final guidance and control of the flow trajectory of the airflow immediately before and after it exits the exhaust port 412, thereby concentrating the airflow and ensuring it flows sufficiently to the first fan 21.

[0164] As an option, referring to Figure 16, the air guide 462 is formed at the end of the exhaust member 46 that is relatively close to the first fan 21 and away from the panel 12, the exhaust member 46 is a hollow sleeve-like structure and protrudes relative to the panel 12 in a direction away from the panel 12, the care lamp 30 and the room.

[0165] The exhaust member 46 and the air guide section 462 can not only guide the heat-dissipating airflow just before it enters the first fan 21 and control its flow trajectory, but can also reduce and suppress the entry of gas from outside the heat-dissipating air passage 43 into the first fan 21. This ensures that as much of the heat-dissipating airflow after heat absorption as possible is taken into the first fan 21, and that the gas in the heat-dissipating air passage 43 is sufficiently discharged. Furthermore, it improves the power utilization efficiency of the first fan 21, allowing more of the power of the first fan 21 to be used for absorbing and discharging the heat-absorbed gas in the heat-dissipating air passage 43.

[0166] Figures 19 to 22 also show a heater with therapeutic functions, and compared to the electrical equipment 100 with therapeutic functions shown in Figures 16 to 17, in the embodiment shown in Figures 19 to 22, the air distribution device 20 further includes a second fan 22 and an airflow passage 202 provided within the housing 11, and the main body 10 has an exhaust window 125 that communicates with the room. One of the first air outlet 431 and the second air outlet 432 faces the intake of the first fan 21, and the other faces the intake of the second fan 22, and at least the exhaust of the first fan 21 is located within the airflow passage 202, and the airflow passage 202 includes at least one exhaust end 203, each exhaust end 203 communicating with either the exhaust window 125 or the outdoors.

[0167] When the first fan 21 operates, a low-pressure region is formed near the intake of the first fan 21, and the pressure is particularly low near the center 211 of the first impeller. As a result, the pressure at one of the first or second air outlets 431 toward the first fan 21 is lower than the pressure at the other, thereby creating a pressure difference at both ends of the heat dissipation air passage 43. The gas enters the heat dissipation air passage 43 under the influence of the pressure difference and then flows toward the one of the first or second air outlets 431 toward the first fan 21, forming a heat dissipation airflow.

[0168] The second fan 22 may be a centrifugal fan including a centrifugal impeller 201, which includes a rotating disc and a plurality of blades attached to the rotating disc, the center of the impeller 2011 being the axis of the rotating disc, the plurality of blades being spaced apart around the center of the impeller 2011 in the circumferential direction of the rotating disc, the rotating disc having pores to allow airflow in, and an air gap being formed between the blades. The intake of the centrifugal fan is the end of the centrifugal impeller 201, i.e., the end face of the rotating disc, and the exhaust of the centrifugal fan is the outer circumference of the centrifugal impeller 201, the end of the centrifugal fan having an intake opening for gas to enter the centrifugal fan, and the air gap passing through the outer circumference of the centrifugal fan facilitates the gas to move away from the outer circumference of the centrifugal fan.

[0169] Optionally, the centrifugal fan further includes a spiral casing corresponding to the outer circumference of the centrifugal impeller 201, and the heat-dissipating airflow after heat absorption flows out of the heat-dissipating air passage 43, flows through the cross section of the rotating disc into the centrifugal fan, then flows into the air gap between the blades, and finally flows out from the outer circumference of the centrifugal impeller 201 and is discharged from the exhaust port of the spiral casing of the centrifugal fan.

[0170] For the sake of explanation, the following explanation will be based on the structure shown in Figures 19 to 20. In the structure shown in Figures 19 to 20, the first air outlet 431 faces the intake of the first fan 21, and the second air outlet 432 is located relatively far from the first fan 21. If the air distribution device 20 further includes a second fan 22 provided in the housing 11, the second air outlet 432 faces the intake of the second fan 22.

[0171] When the first fan 21 is operating and the second fan 22 is not, it is difficult for the gas that enters the heat dissipation air passage 43 to be kept static. As a result, the gas spontaneously moves away from the second air outlet 432 and flows along the heat dissipation air passage 43 towards the first air outlet 431. Therefore, it is not necessary to install a heat dissipation fan at the second air outlet 432 to form a heat dissipation airflow. Compared to the airflow formed by a heat dissipation fan, the heat dissipation airflow formed by the first fan 21 has a stronger wind force and a higher wind speed.

[0172] Based on the operating characteristics of the centrifugal fan, the first fan 21 can quickly discharge the heat-absorbing gas in the heat dissipation air passage 43, emptying the heat dissipation air passage 43, reducing the resistance to new air entering the heat dissipation air passage 43, and also increasing the total amount of new air entering the heat dissipation air passage 43.

[0173] The first air outlet 431 is optionally positioned opposite the center 211 of the first impeller, and the orientation of the opening of the first air outlet 431 positions the first air outlet 431 within the low-pressure region formed when the first fan 21 is operating.

[0174] Selectively, the opening centerline of the first air outlet 431 and the center 211 of the first impeller are parallel to each other, and the center 211 of the first impeller extends into the opening of the first air outlet 431. The opening centerline of the first air outlet 431 is a single imaginary straight line that passes through the geometric center of the opening of the first air outlet 431, and the direction of extension of this line is the same as the instantaneous velocity direction of the heat dissipation airflow flowing out of the first air outlet 431.

[0175] Optionally, after the housing 11 is installed in the suspended ceiling space of the bathroom, the first fan 21, the heat dissipation air passage 43, and the care lamp 30 are sequentially installed in a vertical direction close to the ground.

[0176] Referring to Figures 19 to 20, the opening direction of the first air outlet 431 and the second air outlet 432 is away from the ground, and after the housing 11 is attached to the suspended ceiling of the bathroom, the first air outlet 431 and the second air outlet 432 are opened vertically upward, and the center 2011 of the first impeller extends vertically.

[0177] If the second fan 22 is a centrifugal fan, the center of the impeller of the second fan 22 extends vertically after the housing 11 is mounted on the suspended ceiling of the bathroom.

[0178] Selectively, the opening centerlines of the first air outlet 431 and the second air outlet 432 are both straight lines extending vertically, and the opening shapes of the first air outlet 431 and the second air outlet 432 are not limited and may be circular, square, or other shapes.

[0179] If we define a plane perpendicular to the center 211 of the first impeller as the first airflow cross plane, then the point obtained by orthogonally projecting the center 211 of the first impeller onto the first airflow cross plane lies within the figure obtained by orthogonally projecting the first air outlet 431 onto the first airflow cross plane. In this way, more of the heat-dissipating airflow discharged from the first air outlet 431 can be blown out to the intake of the first fan 21 and absorbed and taken in by the first fan 21 more sufficiently.

[0180] Selectively, the airflow passage 202 includes a ventilation air passage 23, and the exhaust end 203 includes a ventilation exhaust end 2031, which is located at the end of the ventilation air passage 23 that is relatively far from the main body 10 and communicates with the outdoors, and the airflow that enters the ventilation air passage 23 is ultimately discharged to the outdoors from the ventilation exhaust end 2031.

[0181] Selectively, the airflow passage 202 includes a blower air passage 24, the exhaust end 203 includes a blower exhaust end 2032 which communicates with an exhaust window 125 and thereby with the interior space, and the airflow entering the blower exhaust end 2032 is ultimately discharged into the interior space through the exhaust window 125.

[0182] As selectable, referring to Figures 19 to 20 and Figure 22, the airflow passage 202 simultaneously includes a ventilation passage 23 and a blower passage 24, and the exhaust end 203 includes a ventilation exhaust end 2031 and a blower exhaust end 2032.

[0183] The exhaust section of the first fan 21 is abbreviated as the first exhaust section 212, and the exhaust section of the second fan 22 is abbreviated as the second exhaust section 222. The heat dissipation airflow flows into the first fan 21 and then out through the first exhaust section 212. When both exhaust ends 203 are connected to the exhaust window 125, these airflows flow to the exhaust ends 203 and are finally discharged into the bathroom through the exhaust window 125. At this time, the airflow passages 202 are all air supply passages 24, the first exhaust section 212 is located within the air supply passage 24, the first fan 21 provides an air supply function, and the air distribution device 20 operates in air supply mode.

[0184] When all exhaust ends 203 are connected to the outdoors, these airflows flow to the exhaust ends 203 and are eventually discharged outdoors. At this time, all airflow passages 202 are ventilation air passages 23, the first exhaust section 212 is located within the ventilation air passage 23, the first fan 21 performs a ventilation exhaust function, and the air distribution device 20 operates in ventilation mode.

[0185] If there are multiple exhaust ends 203, and some exhaust ends 203 are connected to the exhaust window 125 while the remaining exhaust ends 203 are connected to the outdoors, these airflows are divided into two parts: some airflow is discharged into the room through the exhaust window 125, and the remaining airflow is discharged outdoors. In this case, the first fan 21 can simultaneously perform both air supply and ventilation / exhaust, and the air distribution device 20 operates in both supply mode and ventilation mode.

[0186] Therefore, the first fan 21 can not only function as a power source for generating a heat dissipation airflow, but can also realize at least one of either a ventilation exhaust function or an air supply function.

[0187] Selectively, the airflow passage 202 includes a ventilation passage 23, a supply passage 24, and a common passage, with at least the first exhaust section 212 located within the common passage, both the ventilation passage 23 and the supply passage 24 communicating with the common passage, and the exhaust end 203 includes a ventilation exhaust end 2031 and a supply exhaust end 2032, with the ventilation exhaust end 2031 located at the end of the ventilation passage 23 furthest from the common passage, and the supply exhaust end 2032 located at the end of the supply passage 24 relatively furthest from the common passage.

[0188] The heat-dissipating airflow, having left the heat-dissipating air passage 43, first flows into the common air passage in a concentrated manner. After the first fan 21 operates, these airflows quickly flow into the intake section of the first fan 21, then exit the first fan 21 through the first exhaust section 212. Subsequently, these airflows are divided into two parts: one flows into the ventilation air passage 23 and is eventually discharged outdoors, while the other flows into the air supply air passage 24 and is eventually discharged into the bathroom. Thus, the first fan 21 combines two functions: ventilation exhaust and air supply exhaust.

[0189] Selectively, the intake of the first fan 21 is located within the common air duct. When the first fan 21 operates, it first lowers the air pressure in the common air duct, and under the action of the internal-external pressure difference, the airflow that has left the heat dissipation air duct 43 flows into the common air duct, thus quickly emptying the heat dissipation air duct 43, thereby allowing more air to form a heat dissipation airflow and flow in concentrated into the heat dissipation air duct 43.

[0190] Selectively, the air distribution device 20 further includes a gate that is movable within a common air passage, the gate which can close either the ventilation passage 23 or the air supply passage 24, or open both the ventilation passage 23 and the air supply passage 24 simultaneously.

[0191] The gate may operate the air distribution device 20 in either a blower mode or a ventilation mode by opening one of the ventilation air passage 23 and the blower air passage 24, or it may operate the air distribution device 20 in both a blower mode and a ventilation mode simultaneously by opening both the ventilation air passage 23 and the blower air passage 24 at the same time.

[0192] In the embodiments shown in Figures 19 to 22, the airflow passage 202 includes a ventilation air passage 23 and a blower air passage 24, and the exhaust end 203 includes a ventilation exhaust end 2031 and a blower exhaust end 2032, the ventilation exhaust end 2031 being located at the end of the ventilation air passage 23 relatively far from the main body 10 and communicating with the outdoors, and the blower exhaust end 2032 communicating with the exhaust window 125 and thereby communicating with the interior space of the bathroom. The first exhaust section 212 is located within the ventilation air passage 23, and the air distribution device 20 further includes a second fan 22, the second exhaust section 222 is located within the blower air passage 24.

[0193] As a result, the first fan 21 and the second fan 22 operate in a division of labor, with the first fan 21 functioning as a power source to discharge exhaust gases from the bathroom to the outside, and the second fan 22 functioning as a power source to transport airflow into the bathroom, and even if one fails, it does not interfere with the normal operation of the other.

[0194] Selectively, the first fan 21 and the second fan 22 are provided in parallel along the direction of extension of the heat dissipation air passage 43, the second fan 22 is a centrifugal fan, and the second air outlet 432 faces the intake of the second fan 22. The second exhaust section 222 is the outer circumference of the centrifugal impeller 201 of the second fan 22, and the intake section of the second fan 22 is the end of the centrifugal impeller 201 of the second fan 22. The second air outlet 432 is provided opposite the center 2011 of the impeller of the second fan 22, the center 2011 of the impeller of the second fan 22 is the axis of the rotating disc of the centrifugal impeller 201 of the second fan 22, and is abbreviated as the center 221 of the second impeller.

[0195] As a result, if the first fan 21 operates but the second fan 22 does not, a low-pressure area is formed only near the center 211 of the first impeller, allowing air to enter the heat dissipation air passage 43 from the second air outlet 432, then flow to the first air outlet 431, and finally flow out of the heat dissipation air passage 43 into the first fan 21. The heat dissipation airflow that flows out of the first air outlet 431 is finally discharged outdoors under the suction of the first fan 21. If the second fan 22 operates but the first fan 21 does not, a low-pressure area is formed only near the center 221 of the second impeller, allowing air to enter the heat dissipation air passage 43 from the first air outlet 431, then flow to the second air outlet 432, and finally flow out of the heat dissipation air passage 43 into the second fan 22. The heat dissipation airflow that flows out of the second air outlet 432 is finally discharged into the bathroom under the suction of the second fan 22.

[0196] The first fan 21 or the second fan 22 may be selected to generate a heat dissipation airflow. However, when the first fan 21 and the second fan 22 operate simultaneously, both the first air outlet 431 and the second air outlet 432 may be in a low-pressure state. In this case, it is difficult to form a large pressure difference at both ends of the heat dissipation air passage 43, and therefore, it is difficult to generate a heat dissipation airflow within the heat dissipation air passage 43.

[0197] Referring to Figures 19 to 20, the heat dissipation structure 40 further includes an exhaust member 46, which is provided at the first air outlet 431 and protrudes outward from the heat dissipation air passage 43, extending toward the first fan 21 in a direction away from the ground, thereby making the distance d between the exhaust member 46 and the intake of the first fan 21 smaller than the distance c between the second air outlet 432 and the intake of the second fan 22.

[0198] This ensures that the majority of the air flowing into the second fan 22 comes from inside the bathroom, reducing the amount of gas flowing out of the heat dissipation air passage 43 and into the second fan 22. At the same time, the exhaust member 46 guides more of the heat dissipation airflow in the heat dissipation air passage 43 to flow out of the first air outlet 431 and into the first fan 21. The exhaust member 46 exerts a certain blocking effect, preventing gas from inside the bathroom from flowing into the first fan 21, thus achieving the objective of forming a heat dissipation airflow that relies mainly on the first fan 21.

[0199] The exhaust member 46 may optionally be provided in the second air outlet 432, specifically, the exhaust member 46 is provided in the one of the two air outlets 432 that faces the first fan 21.

[0200] When the air distribution device 20 operates in fan mode, it can either discharge room temperature air (15°C to 25°C) into the bathroom or a heated airflow at a temperature higher than 25°C into the bathroom. In order for the air distribution device 20 to discharge a heated airflow into the bathroom, the air distribution device 20 further includes a heater, which is located in the airflow passage 24 and is used to heat the airflow that enters the airflow passage 24 to form a heated airflow.

[0201] If the air distribution device 20 includes a heater located in the air supply passage 24, the first exhaust section 212 is located in the ventilation passage 23, and the care lamp 30 and the first fan 21 are coupled together. When the care lamp 30 operates, it can trigger the operation of the first fan 21. Therefore, when the care lamp 30 operates, the first fan 21 always operates, and the air distribution device 20 operates in both a fan mode and a ventilation mode. At this time, the second fan 22 discharges a heated airflow into the bathroom, but at least a portion of the hot air in the bathroom can be discharged to the outside. Thus, the temperature inside the bathroom can be maintained at a relatively low level. In this way, it is possible to prevent the temperature of the heat-dissipating airflow flowing through the heat-dissipating air passage 43 from becoming too high due to excessively high ambient temperatures, thus preventing the problem of poor cooling effect of the care lamp 30.

[0202] Selectively, the main body 10 is provided with a first airflow inlet 131 that communicates with the airflow passage 202. Referring to Figures 19 to 20, the intake portion of the first fan 21 is exposed from the first airflow inlet 131, and the first air outlet 431 faces the intake portion of the first fan 21 and is thus positioned opposite the first airflow inlet 131. The opening area of ​​the first air outlet 431 is larger than the area of ​​the intake portion of the first fan 21.

[0203] Selectively, the opening area of ​​the first air outlet 431 is larger than the opening area of ​​the intake port 411 of the intake section of the first fan 21.

[0204] In the embodiment shown in Figure 20, both the first air outlet 431 and the first air inlet 131 are circular openings, the opening diameter of the first air outlet 431 is b, and the opening diameter of the first air inlet 131 is a, where b > a.

[0205] Selectively, the exhaust member 46 has an annular structure, and an opening for the first air outlet 431 is formed at the opening edge of the end of the exhaust member 46 that is relatively close to the first fan 21, and the diameter b is the inner diameter of the end of the exhaust member 46 that is relatively close to the first fan 21.

[0206] This ensures that all of the heat-dissipating airflow flowing out of the heat-dissipating air passage 43 flows into the first fan 21 due to the suction force of the first fan 21, which is advantageous for maximizing the flow velocity of the heat-dissipating airflow, increasing the amount of heat-dissipating airflow entering the heat-dissipating air passage 43, and obtaining a more pronounced heat dissipation effect.

[0207] In the embodiments shown in Figures 19 to 20 and Figure 22, the airflow passage 202 includes a supply air passage 24 and a ventilation air passage 23 that are isolated from each other, and the first airflow inlet 131 communicates with the ventilation air passage 23. The main body 10 is further provided with a second airflow inlet 132 that communicates with the supply air passage 24, at least a portion of the ventilation air passage 23 is located inside the main body 10, and at least a portion of the supply air passage 24 is also located inside the main body 10, and both the first airflow inlet 131 and the second airflow inlet 132 are located on the side of the housing 11 that is relatively close to the ground.

[0208] Selectively, the first air inlet 131 and the second air inlet 132 are opened on the side of the housing 11 that is relatively closer to the panel 12, the safety lamp 30, and the interior of the room.

[0209] In the embodiments shown in Figures 19 to 21 and 22, some of the air in the bathroom enters the airflow passage 24 directly from the second airflow inlet 132, then forms an airflow under the operation of the second fan 22, and the airflow is discharged back into the bathroom from the exhaust window 125. Most of the air forming the airflow does not flow through the heat dissipation passage 43, and the remaining air in the bathroom first flows into the heat dissipation passage 43 to form a heat dissipation airflow, which absorbs heat from the protective lamp 30 and then exits the heat dissipation passage 43. These airflows then flow into the ventilation passage 23 from the first airflow inlet 131 under the operation of the first fan 21 and are finally discharged outdoors.

[0210] Optionally, after the housing 11 is mounted on the suspended ceiling of the bathroom, both the first fan 21 and the second fan 22 are provided inside the housing 11, and the housing 11, the heat dissipation air passage 43, and the care lamp 30 are arranged in a vertical direction close to the ground, with the opening direction of the second air outlet 432 being away from the ground, and after the housing 11 is mounted on the suspended ceiling of the bathroom, the second air outlet 432 is opened facing vertically, and the center 221 of the second impeller extends vertically.

[0211] Selectively, the opening centerline of the second air outlet 432 and the center 221 of the second impeller are parallel to each other, and the center 221 of the second impeller extends into the opening of the second air outlet 432. The opening centerline of the second air outlet 432 is a single imaginary straight line that passes through the geometric center of the second air outlet 432, and the direction of extension of this line is parallel to the opening centerline of the first air outlet 431.

[0212] If we define a plane perpendicular to the center 221 of the second impeller as the second airflow cross plane, then the point obtained by orthogonally projecting the center 221 of the second impeller onto the second airflow cross plane lies within the figure obtained by orthogonally projecting the second air outlet 432 onto the second airflow cross plane. In this way, when the second fan 22 is responsible for generating the heat dissipation airflow, the heat dissipation airflow discharged from the second air outlet 432 can be blown out to the intake of the second fan 22 to a greater extent and taken into the second fan 22 more sufficiently.

[0213] Selectively, the first fan 21, the second fan 22, at least a portion of the ventilation air passage 23, and at least a portion of the blower air passage 24 are all located on the side of the panel 12 away from the ground, and as shown in Figure 22, at least a portion of the ventilation air passage 23 and at least a portion of the blower air passage 24 are both located inside the housing 11.

[0214] The exhaust window 125 may be selectively located in the housing 11, in the panel 12, or between the housing 11 and the panel 12, for example, between the bottom of the housing 11 and the side of the panel 12 that is relatively closer to the bottom of the housing 11.
