Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to an air dispatching device. Background Art

[0002] Yuba, also known as bathroom heater, is an air conditioning device that can transport, supply and transfer air indoors, along with ventilation fans and fresh air blowers. There is a type of Yuba equipped with an irradiator, which can be a lighting lamp or a beauty lamp with a therapeutic effect. The beauty lamp is used to emit a beauty light to radiate energy to the human skin and perform skin care treatments.

[0003] The irradiating element generates heat and heats up during operation, so it is necessary to dissipate heat and cool the irradiating element to avoid overheating of the irradiating element and weakening the lighting effect. The usual countermeasure is to add a cooling fan or a cooling blower to generate a cooling airflow, and remove the heat of the irradiating element through convection heat transfer between the cooling airflow and the irradiating element. The above heat dissipation means will increase the structural complexity and volume weight of the air dispatching device. Utility Model Content

[0004] In view of this, the utility model provides an air dispatching device which can dissipate heat and cool down an irradiating element without increasing the structural complexity, volume and weight of the entire device.

[0005] The air dispatching device provided by the utility model comprises an irradiating member, an air duct group and an air-driving member, the air duct group comprises a vortex section, an air supply duct and a heat dissipation duct, the air supply duct and the heat dissipation duct are both branched and extended from the vortex section; the irradiating member is thermally connected to the heat dissipation duct; the air-driving member comprises a wind wheel connected to the vortex section, the wind wheel is used to drive the gas to flow along the vortex section, so that the airflow is diverted by the air supply duct and the heat dissipation duct.

[0006] The beneficial effect of the utility model is that after the wind drive component is started, not only a part of the gas is driven from the vortex section into the air supply duct to start the air scheduling function, but also a part of the air is driven from the vortex section into the heat dissipation duct. The air entering the heat dissipation duct forms a heat dissipation airflow that can dissipate heat and cool the irradiated component. There is no need to add a heat dissipation fan or a heat dissipation blower to obtain the heat dissipation airflow, thereby avoiding the increase in volume and weight caused by the heat dissipation fan or the heat dissipation blower. Therefore, compared with similar products equipped with existing heat dissipation fans or heat dissipation blowers, the air scheduling device of the utility model has a simpler structure.

[0007] In one embodiment, the heat dissipation duct includes a diversion section branched from the vortex section and a heat absorption section connected to the diversion section. The diversion section and the air supply duct are arranged along the axial direction of the wind wheel, and the heat absorption section is thermally connected to the irradiation member.

[0008] Such an arrangement avoids the situation where the two airflows respectively flowing into the air supply duct and the diverter section have insufficient kinetic energy due to the diverter section and the air supply duct not being arranged along the axial direction of the wind wheel.

[0009] In one embodiment, the air duct group further includes an air flow dividing portion located between the air supply duct and the diversion section.

[0010] With such an arrangement, the two air flows respectively flowing into the air supply duct and the diversion section will not interfere with each other and reduce the kinetic energy.

[0011] In one embodiment, the air supply duct includes a blowing duct branched from the vortex section, the wind wheel includes a blowing wheel capable of driving gas into the blowing duct, and the diversion section and the blowing duct are both within the axial size range of the blowing wheel.

[0012] With such arrangement, when the blowing impeller rotates to enable the air dispatching device to operate the blowing function, the heat dissipation airflow will be received in the heat dissipation duct, thereby satisfying the heat dissipation and cooling needs of the irradiation component in the most basic usage scenario of the air dispatching device. The most basic usage scenario is that the user receives the blowing from the blowing duct and the irradiation of the irradiation component at the same time; the two airflows flowing into the blowing duct and the diversion section respectively from the vortex section can be driven by the same blowing impeller to generate and obtain kinetic energy, thereby simplifying the composition and structure of the air dispatching device.

[0013] In one embodiment, the heat absorption section is bent relative to the diversion section and is located at an end of the wind wheel close to the ground.

[0014] With such arrangement, the heat absorbing section is reasonably positioned, and the heat absorbing section is convenient to form a heat-conducting connection with the irradiating element, thereby reducing the structural complexity and assembly difficulty of the air dispatching device.

[0015] In one embodiment, the irradiating element is disposed at one end of the wind wheel close to the ground, and the heat absorbing section is located between the irradiating element and the wind wheel.

[0016] With this arrangement, the air conditioning device has a reasonable structural layout and is easy to assemble. The relative positions of the heat absorption section and the irradiation element can take into account both the heat dissipation requirements of the irradiation element and the light emission of the irradiation element into the room, thereby avoiding the overall structure of the air conditioning device being too flat.

[0017] In one embodiment, the heat dissipation duct also includes a guide portion arranged between the diversion section and the heat absorption section, the guide portion includes a starting end close to the diversion section and an outlet end close to the heat absorption section, and the distance from the guide portion to the ground decreases from the starting end to the outlet end.

[0018] With such arrangement, the guide part can provide steering assistance and guidance for the heat dissipation airflow flowing out of the diversion section so that the heat dissipation airflow can flow into the heat absorption section smoothly, with low resistance and low loss after turning.

[0019] In one embodiment, the air dispatching device further includes a chassis that at least accommodates the vortex section and the diverter section, and a blocking ring connected to the chassis, wherein the blocking ring connects the diverter section and the heat absorption section located outside the chassis.

[0020] Such a configuration can ensure that the heat dissipation airflow flowing out of the diversion section can flow smoothly into the heat absorption section through the blocking ring without being disturbed or impacted by the ambient airflow. In particular, the blocking ring can block the air flowing into the chassis from the heat dissipation airflow to avoid mutual impact and interference between the two airflows.

[0021] In one embodiment, the air dispatching device further comprises a heat collecting cover covering the irradiating member, a heat absorbing section is formed between the heat collecting cover and the irradiating member, and the heat collecting cover is penetrated to form an inlet connected to the blocking ring.

[0022] With this arrangement, it is easier to connect the blocking ring to the chassis and connect it to the diversion section. The blocking ring and the chassis can be connected and the diversion section can be connected, which reduces the assembly operation steps of the air dispatching device.

[0023] In one embodiment, the blocking ring is integrally formed with the heat collecting cover; and / or, one end of the blocking ring away from the heat collecting cover is plugged into and extends into the chassis; and / or, the blocking ring is convexly arranged on a side of the heat collecting cover away from the irradiating element and close to the chassis.

[0024] With such arrangement, the connection between the obstruction ring and the diversion section is easier to achieve, the connection between the obstruction ring and the chassis is more secure, and the assembly operation of the air dispatching device is less difficult and involves fewer steps.

[0025] In one embodiment, the air supply duct at least includes a blowing duct branched from the vortex section, the wind wheel includes a blowing wheel capable of driving the gas from the vortex section into the blowing duct, and a heating element is provided in the blowing duct.

[0026] With such arrangement, a part of the airflow flowing along the vortex section can flow into the diversion section in advance to form a heat dissipation airflow. The heat dissipation airflow will not be heated by the heating element, thereby ensuring that the heat dissipation airflow maintains a low temperature to facilitate heat dissipation and cooling of the irradiated element. The other part of the airflow will be heated by the heating element to become warm airflow.

[0027] In one embodiment, the air supply duct includes a blowing duct branched from the vortex section and extending into the room; and / or, the air supply duct includes a ventilation duct branched from the vortex section and extending into the room.

[0028] In one embodiment, the wind wheel includes a blowing wind wheel and a ventilation wind wheel arranged along the axial direction, and the blowing wind wheel and the ventilation wind wheel are used to drive airflow into the blowing air duct and the ventilation air duct respectively.

[0029] With this arrangement, the air dispatching device is compatible with both the blowing function and the ventilation function, and the blowing impeller and the ventilation impeller operate in a division of labor to ensure that both the blowing function and the ventilation function can operate stably.

[0030] In one embodiment, the blowing wheel is coaxially fixed with the ventilation wheel. When the wind driving member rotates forward, the blowing wheel discharges wind. When the wind driving member rotates reversely, the ventilation wheel discharges wind. The airflow in the vortex section can be driven into the heat dissipation duct by the blowing wheel.

[0031] With such an arrangement, only one driving source needs to be installed in the wind driving member to connect and drive the blowing impeller and the ventilation impeller to rotate respectively. The wind driving member can drive the blowing impeller and the ventilation impeller to rotate respectively through forward rotation and reverse rotation, thereby respectively operating the blowing function and the ventilation function. When it is necessary to switch the mode of the air scheduling function, it is only necessary to change the operating direction of the wind driving member, thereby realizing the blowing function and the ventilation function running at different times.

[0032] In one embodiment, the air duct group includes a guide member and a special-shaped member arranged on the periphery of the wind wheel, the special-shaped member includes a guide plate, a first guide plate and a second guide plate respectively bent and connected to the two ends of the guide plate, the wind wheel is located between the guide member and the guide plate, at least a portion of the blowing air duct is formed between the guide member and the first guide plate, and at least a portion of the ventilation air duct is formed between the guide member and the second guide plate.

[0033] With such arrangement, the blowing air duct and the ventilation air duct are easier to obtain, the structure of the air duct group is simpler, and the structural complexity and assembly difficulty of the air dispatching device are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0045] The utility model provides an air regulation device 100 equipped with a wind-driving member 60 and an irradiating member 20, which has both air regulation function and light irradiation function. The air regulation function is realized based on the wind-driving member 60, including a blowing function of blowing air into the room and a ventilation function of exhausting indoor air to the outdoors; the light irradiation function is realized based on the irradiating member 20, and the irradiating member 20 can be / include a lighting lamp that provides conventional lighting, can also be / include an atmosphere lamp that adjusts the indoor color tone, and can also be / include a maintenance lamp with a beauty and recuperation function, which is also called a beauty lamp, which emits maintenance light to radiate energy to human skin for skin care and treatment.

[0046] The air dispatching device 100 of the utility model can be used in the bathroom or in other indoor places. In some embodiments, the air dispatching device 100 of the utility model is a heater equipped with an irradiation member 20 and having both a blowing function and a ventilation function. At least a part of the air dispatching device 100 can be arranged in the ceiling space between the bathroom ceiling and the ceiling board. It can be understood that the air dispatching device 100 can also be installed in other ways so as to be suspended relative to the ground, and is not limited to being installed between the ceiling and the ceiling board. For the convenience of description, the air dispatching device 100 is introduced below by taking a heater equipped with an irradiation member 20 as an example.

[0047] The air driving member 60 is used to drive the air flow to accelerate and form an airflow. When the air dispatching device 100 operates the blowing function, the airflow driven by the air driving member 60 includes the blowing airflow flowing into the room; when the air dispatching device 100 operates the ventilation function, the airflow driven by the air driving member 60 includes the exhaust airflow flowing outdoors. In some embodiments of the present utility model, the air dispatching device 100 can operate the blowing function and the ventilation function at the same time, and in other embodiments, the blowing function and the ventilation function are not operated at the same time.

[0048] The luminous irradiation function includes a conventional lighting function, an atmosphere adjustment function, and a beauty maintenance function. In some embodiments, the air dispatching device 100 is compatible with the conventional lighting function, the atmosphere adjustment function, and the beauty maintenance function, and the irradiation part 20 accordingly includes a lighting lamp, an atmosphere lamp, and a maintenance lamp; in other embodiments, the air dispatching device 100 has any one or any two of the conventional lighting function, the atmosphere adjustment function, and the beauty maintenance function, and the irradiation part 20 accordingly includes any one or any two of the lighting lamp, the atmosphere lamp, and the maintenance lamp.

[0049] The air conditioning device 100 includes a body, and the air driving element 60 and the irradiating element 20 are both installed on the body. Figure 1 and Figure 6In some embodiments, the fuselage includes a chassis 10 accommodating a wind-repelling member 60 and a panel 30 on which an irradiating member 20 is installed. The chassis 10 includes a box body 12 having an opening and accommodating the wind-repelling member 60, and a wind collecting plate 11 covering the opening of the box body 12. At least a portion of the chassis 10 including the box body 12 can be installed in a ceiling space between a ceiling and a ceiling panel. When the box body 12 is installed in place in the ceiling space, the wind collecting plate 11 covers a side of the box body 12 close to the ground and closes the opening of the box body 12 facing the ground.

[0050] Further, the irradiation member 20 and the panel 30 are arranged on the side of the wind collecting plate 11 away from the box 12, and the light-emitting part of the irradiation member 20 faces the room and the ground when the box 12 is installed in place in the ceiling space, and the side of the panel 30 away from the chassis 10 faces the room and the ground when the box 12 is installed in place in the ceiling space. Preferably, the irradiation member 20 and the panel 30 are spliced ​​and installed to form a panel assembly in the form of a plate, wherein the box 12, the wind collecting plate 11 and the panel assembly are installed in a stacked manner in the vertical direction.

[0051] Optional, Figure 1 and Figure 6 The air dispatching device 100 shown has both blowing function and ventilation function. The air collecting plate 11 is provided with an air collecting port 111 and an air blowing port 1122. The air collecting port 111 is connected with the air inlet of the wind driving member 60. The housing 12 is provided with an air exchange port 121 connected with the outdoors. After the wind driving member 60 is started, the indoor air can flow from the air collecting port 111 into the chassis 10 and then into the air inlet. When the air dispatching device 100 operates the blowing function, a part of the airflow driven by the wind driving member 60 is defined as the blowing airflow, which flows out of the chassis 10 from the air blowing port 1122 and then blows into the indoor room; when the air dispatching device 100 operates the ventilation function, a part of the airflow driven by the wind driving member 60 is defined as the exhaust airflow, which flows out of the chassis 10 from the air exchange port 121 and then blows to the outdoors.

[0052] See again Figure 1 and Figure 6 The panel 30 is provided with an air outlet window 32 and an air inlet 31. The air outlet window 32 penetrates the side of the panel 30 away from the chassis 10 and toward the indoor room, and the air outlet window 32 is connected to the air blowing port 1122. The blowing air flow is blown into the indoor room through the air blowing port 1122 and the air outlet window 32 in sequence. The air inlet 31 penetrates the side of the panel 30 away from the chassis 10 and toward the indoor room. A gap connected to the air inlet 31 is provided between the panel 30 and the air collecting plate 11. After the air driving member 60 drives, the air in the room flows into the air collecting port 111 through the air inlet 31 and the gap in sequence.

[0053] It can be understood that in other embodiments, the air collecting port 111 and the air blowing port 1122 can also be opened at other positions of the fuselage and are not limited to being opened on the air collecting plate 11, and it is not necessary to form the air intake port 31 in a manner of penetrating both sides of the panel 30. In some embodiments, the air intake port 31 is formed by the gap between the panel 30 and the air collecting plate 11.

[0054] Specifically, in some embodiments, the irradiation member 20 includes a lamp board and a light emitter disposed on one side of the lamp board, the light emitting portion includes the light emitter, and the side of the lamp board where the light emitter is not disposed forms the backlight portion of the irradiation member 20. When the light emitter emits light, the backlight portion accumulates heat and the temperature rises, so the backlight portion is equivalent to the heat storage portion of the irradiation member 20. When the box 12 is arranged in place in the ceiling space, the backlight portion is the side of the lamp board away from the room and the ground, and the backlight portion is spaced apart from the air collecting plate 11 to prevent the backlight portion from burning the box 10, and the space between the backlight portion and the air collecting plate 11 allows the backlight portion to dissipate heat.

[0055] Optionally, the illuminating element 20 further includes a heat sink thermally connected to the backlight portion, and the heat sink includes heat sink fins protruding from the backlight portion, thereby increasing the heat dissipation area of ​​the illuminating element 20 .

[0056] In some embodiments, the panel 30 can also be omitted, and the irradiation member 20 is separately installed on the side of the air collecting plate 11 away from the box body 12, and the irradiation member 20 and the air collecting plate 11 are spaced apart. The space between the irradiation member 20 and the air collecting plate 11 can prevent the irradiation member 20 from burning the chassis 10, and the space between the irradiation member 20 and the air collecting plate 11 can allow the irradiation member 20 to dissipate heat, and also provide space for arranging a heat sink.

[0057] See also Figure 1-2 In some embodiments, the wind driving member 60 includes a wind wheel disposed in the chassis 10, and the wind wheel includes a blowing wind wheel 61 and a ventilation wind wheel 62. When the wind driving member 60 is running and drives the blowing wind wheel 61 to rotate, the blowing wind wheel 61 will drive the air to flow and form a blowing airflow, and the air dispatching device 100 will perform a blowing function at this time. When the wind driving member 60 is running and drives the ventilation wind wheel 62 to rotate, the ventilation wind wheel 62 will drive the air to flow and form an exhaust airflow, and the air dispatching device 100 will perform a ventilation function at this time.

[0058] The blowing impeller 61 and the ventilation impeller 62 are both centrifugal impellers, and they can drive air flow by rotating when the wind driving member 60 is in operation. It can be understood that in other embodiments, any one or both of the blowing impeller 61 and the ventilation impeller 62 can also be replaced by other types of wind driving structures.

[0059] Specifically, the air inlet and the air outlet of the blowing wheel 61 are respectively the end of the blowing wheel 61 and the peripheral side of the blowing wheel 61, the air inlet and the air outlet of the ventilation wheel 62 are respectively the end of the ventilation wheel 62 and the peripheral side of the ventilation wheel 62, and the air collecting port 111 connects the air inlet of the blowing wheel 61 with the air inlet of the ventilation wheel 62. Optionally, when the air collecting port 111 is opened on the air collecting plate 11, the axis of the blowing wheel 61 and the axis of the ventilation wheel 62 are both perpendicular to the air collecting plate 11 so that the air collecting port 111 connects the air inlet of the blowing wheel 61 with the air inlet of the ventilation wheel 62.

[0060] Indoor air flows into the box body 12 through the air collecting port 111. When the air flowing into the blowing wheel 61 is discharged from the peripheral side of the blowing wheel 61, part of the air forms a blowing airflow; when the air flowing into the ventilation wheel 62 is discharged from the peripheral side of the ventilation wheel 62, part of the air forms an exhaust gas airflow.

[0061] Optional, see Figure 1 and Figure 2 In some embodiments, the blowing wheel 61 and the ventilation wheel 62 are coaxially arranged, and the axes of the two are the axes of the wind wheels. The indoor air flows into the box body 12 through the air collecting port 111, and then can flow into the blowing wheel 61 and the ventilation wheel 62 in sequence along the extension direction of the axis of the wind wheel, or flow into the ventilation wheel 62 and the blowing wheel 61 in sequence along the extension direction of the axis of the wind wheel.

[0062] Optional, in Figure 1 to Figure 6 In the air dispatching device 100 shown, the blowing impeller 61 and the ventilation impeller 62 are coaxial and fixedly connected, and the wind driving member 60 includes a driving part connected to the impeller, and the driving part can run forward to drive the blowing impeller 61 and the ventilation impeller 62 to rotate forward, and can also run reversely to drive the blowing impeller 61 and the ventilation impeller 62 to rotate reversely. When the forward transport behavior rotates clockwise, the reverse operation rotates counterclockwise, and when the forward transport behavior rotates counterclockwise, the reverse operation rotates clockwise. The driving part changes the running direction according to the user's selection of switching different air dispatching functions.

[0063] It is worth noting that when the blowing impeller 61 and the ventilation impeller 62 rotate synchronously, only one of the two can effectively drive the air flow. For example, in some embodiments, when the impeller rotates forward, only the blowing impeller 61 effectively drives the air flow to generate the blowing airflow, and when the impeller rotates reversely, only the ventilation impeller 62 effectively drives the air flow to generate the exhaust airflow; in other embodiments, when the impeller rotates forward, only the ventilation impeller 62 effectively drives the air flow to generate the exhaust airflow, and when the impeller rotates reversely, only the blowing impeller 61 effectively drives the air flow to generate the blowing airflow.

[0064] Specifically, see Figure 2The circumferential side of the blowing wheel 61 has a plurality of first blades 611 arranged at intervals, and a first air outlet gap 612 for exhausting air is formed between any two of the first blades 611. The circumferential side of the ventilation wheel 62 has a plurality of second blades 621 arranged at intervals, and a second air outlet gap 622 for exhausting air is formed between any two of the second blades 621. The first blades 611 and the second blades 621 have opposite rotation directions, so the wind wheel will selectively operate the blowing function and the ventilation function instead of operating the blowing function and the ventilation function at the same time.

[0065] In some embodiments, one end of each first blade 611 close to the axis of the wind wheel is located on the clockwise side of the middle of the first blade 611, and the other end of the first blade 611 away from the axis of the wind wheel is located on the counterclockwise side of the middle of the first blade 611; one end of each second blade 621 close to the axis of the wind wheel is located on the counterclockwise side of the middle of the second blade 621, and the other end of the second blade 621 away from the axis of the wind wheel is located on the clockwise side of the middle of the second blade 621;

[0066] In other embodiments, one end of each first fan blade 611 close to the axis of the wind wheel is located on the counterclockwise side of the middle part of the first fan blade 611, and the other end of the first fan blade 611 away from the axis of the wind wheel is located on the clockwise side of the middle part of the first fan blade 611; one end of each second fan blade 621 close to the axis of the wind wheel is located on the clockwise side of the middle part of the second fan blade 621, and the other end of the second fan blade 621 away from the axis of the wind wheel is located on the counterclockwise side of the middle part of the second fan blade 621.

[0067] In other embodiments, the blowing wheel 61 and the ventilation wheel 62 may also be arranged non-coaxially. For example, the wind driving part 60 includes a blowing drive unit and a ventilation drive unit. The blowing drive unit is connected to the blowing wheel 61 and independently drives and controls the rotation of the blowing wheel 61. The ventilation drive unit is connected to the ventilation wheel 62 and independently drives and controls the rotation of the ventilation wheel 62. The blowing drive unit and the ventilation drive unit can be started and operated at the same time to generate power, or they can be started and operated at different times.

[0068] In the present invention, the fuselage is formed with an air duct group 40 , which includes a vortex section 401 , an air supply duct branched and extended from the vortex section 401 , and a heat dissipation duct 50 branched and extended from the vortex section 401 . Figure 1 to Figure 6 In the illustrated embodiment, the wind wheel, the vortex section 401 and the air supply duct are all located in the chassis 10, the irradiation member 20 and the panel 30 are both located on the side of the wind wheel and the vortex section 401 close to the ground, and at least a portion of the heat dissipation duct 50 is located between the irradiation member 20 and the wind wheel so as to be thermally connected to the irradiation member 20, that is, at least a portion of the heat dissipation duct 50 is located on the side of the irradiation member 20 facing away from the ground.

[0069] Optionally, the vortex section 401 is arranged around the circumferential side of the wind wheel along the circumference of the wind wheel. More specifically, the blowing wind wheel 61 and the ventilation wind wheel 62 are coaxially arranged, and the vortex section 401 is an annular flow channel surrounding the blowing wind wheel 61 and the ventilation wind wheel 62.

[0070] In some embodiments, the wind wheel includes a blowing wheel 61 and a ventilation wheel 62, the air supply duct includes a blowing duct 41 connected to the blowing port 1122 for conveying blowing air flow to the indoor room, and also includes a ventilation duct 42 connected to the ventilation port 121 for conveying exhaust gas flow to the outdoors, and the blowing duct 41 and the ventilation duct 42 are both extended from the vortex section 401.

[0071] Furthermore, the air outlet of the blowing wheel 61 and the air outlet of the ventilation wheel 62 are both connected to the vortex section 401, that is, the first air outlet gap 612 and the second air outlet gap 622 are connected to the vortex section 401, and the blowing wheel 61 is responsible for driving the air from the vortex section 401 into the blowing duct 41, and the ventilation wheel 62 is responsible for driving the air from the vortex section 401 into the ventilation duct 42.

[0072] Figure 1 to Figure 6 In the illustrated embodiment, the blowing wheel 61 is coaxially fixedly connected with the ventilation wheel 62. When the blowing wheel 61 rotates counterclockwise, air is discharged from the first air outlet gap 612, and when the ventilation wheel 62 rotates clockwise, air is discharged from the second air outlet gap 622. When the air-driving member 60 rotates forward, the blowing wheel 61 rotates counterclockwise synchronously with the ventilation wheel 62, and when the air-driving member 60 rotates reversely, the ventilation wheel 62 rotates clockwise synchronously with the blowing wheel 61. When the blowing wheel 61 rotates counterclockwise, a part of the air is driven into the heat dissipation duct 50, while when the ventilation wheel 62 rotates clockwise, no airflow enters the heat dissipation duct 50.

[0073] Furthermore, the heat dissipation duct 50 is thermally connected to the irradiation member 20, and specifically, the inner wall of the heat dissipation duct 50 is thermally connected to the heat storage part (such as the backlight part) of the irradiation member 20. When the wind driving member is in operation, the air is driven out of the vortex section 401 by the wind wheel, and then these airflows are divided by the air supply duct and the heat dissipation duct 50, a part of the airflow is driven into the air supply duct to form a blowing airflow and / or an exhaust airflow, and the other part is driven into the heat dissipation duct 50 to form a heat dissipation airflow, and the heat dissipation airflow is used to dissipate heat and cool the irradiation member 20.

[0074] The principle of heat dissipation and cooling of the irradiation component 20 by the heat dissipation airflow includes: 1) the heat dissipation airflow uses kinetic energy to drive out the heat generated from the irradiation component 20 and conducted into the heat dissipation duct 50 from the heat dissipation duct 50; 2) convection heat transfer occurs between the heat dissipation airflow and the inner wall of the heat dissipation duct 50, and heat conduction occurs between the inner wall of the heat dissipation duct 50 and the irradiation component 20, and the heat of the irradiation component 20 is removed through the flow contact between the heat dissipation airflow and the inner wall of the heat dissipation duct 50.

[0075] Specifically, the airflow driven by the wind wheel from the vortex section 401 into the blowing air duct 41 forms a blowing airflow, and the airflow driven by the wind wheel from the vortex section 401 into the ventilation air duct 42 forms an exhaust airflow. Part or all of the blowing airflow is generated by the rotation of the blowing wind wheel 61, and part or all of the exhaust airflow is generated by the rotation of the ventilation wind wheel 62. The heat dissipation airflow can be partially or completely generated by the rotation of the blowing wind wheel 61, and can also be partially or completely generated by the rotation of the ventilation wind wheel 62.

[0076] Preferably, in some embodiments, the heat dissipation airflow comes from the blowing wheel 61. When the blowing wheel 61 rotates, the air is driven out from the vortex section 401. Then, the air is diverted by the blowing duct 41 and the heat dissipation duct 50 to form a blowing airflow and a heat dissipation airflow. The blowing function and the heat dissipation of the irradiation part 20 are performed simultaneously. When the ventilation wheel 62 rotates, the air is driven out from the vortex section 401 and then flows into the ventilation duct 42 to form an exhaust gas airflow.

[0077] See also Figure 3-4 In some embodiments, the blowing duct 41 and the ventilation duct 42 are arranged along the axis of the wind driving member 60, and the axis of the wind driving member 60 is the axis of the wind wheel. The axis of the blowing wheel 61 is parallel to or coincides with the axis of the ventilation wheel 62, that is, the blowing wheel 61 and the ventilation wheel 62 are arranged along the axial direction of the wind driving member 60.

[0078] In some embodiments, when the chassis 10 is arranged in place in the ceiling space, the axis of the wind wheel is perpendicular to the wind collecting plate 11, and the blowing wind wheel 61 and the ventilation wind wheel 62 are arranged coaxially with the axis of the wind wheel, the blowing air duct 41 and the ventilation air duct 42 are stacked in the vertical direction. Optionally, the blowing air duct 41 is arranged between the ventilation air duct 42 and the wind collecting plate 11, and the blowing air duct 41 penetrates the wind collecting plate 11 to form a blowing port 1122. When the chassis 10 is arranged in place in the ceiling space, the vertical height of the flow trajectory of the blowing air flow is lower than the vertical height of the flow trajectory of the exhaust gas flow.

[0079] Specifically, see Figure 3 to Figure 5 The air duct group 40 includes a guide member 43 and a special-shaped member 44 which are arranged in the box body 12 and on the peripheral side of the wind wheel. The guide member 43 is an arc-shaped plate structure, and the center line of the curvature of the guide member 43 is located on the side of the guide member 43 close to the wind wheel. The special-shaped member 44 includes an arc-shaped guide plate 443, a first guide plate 441 bent and connected to one end of the guide plate 443, and a second guide plate 442 bent and connected to the other end of the guide plate 443. The wind wheel is located between the guide member 43 and the guide plate 443, and the center line of the curvature of the guide plate 443 is located on the side of the guide plate 443 close to the wind wheel.

[0080] See also Figure 3 to Figure 5The vortex section 401 is formed between the guide member 43 and the guide plate 443. More specifically, the blowing impeller 61 and the ventilation impeller 62 are coaxially arranged, and the first arc-shaped interval between the guide member 43 and the peripheral side of the impeller and the second arc-shaped interval between the guide plate 443 and the peripheral side of the impeller are connected to form the vortex section 401.

[0081] See also Figure 3 to Figure 5 The first guide plate 441 is bent toward the side of the guide plate 443 away from the guide member 43, so that the bending portion between the first guide plate 441 and the guide plate 443 forms a blowing volute tongue 444, and the second guide plate 442 is bent toward the side of the guide plate 443 away from the guide member 43, so that the bending portion between the second guide plate 442 and the guide plate 443 forms a ventilation volute tongue 445, and at least a part of the blowing air duct 41 is formed between one end of the guide member 43 and the first guide plate 441, and at least a part of the ventilation air duct 42 is formed between the other end of the guide member 43 and the second guide plate 442. The blowing impeller 61 is coaxially fixedly connected with the ventilation impeller 62. When the impeller rotates counterclockwise, the blowing impeller 61 discharges air from the side and drives the air to form a blowing airflow, such as Figure 4 As shown, when the wind wheel rotates clockwise, the ventilation wind wheel 62 discharges air from the side and drives the air to form an exhaust gas flow, as shown in FIG. Figure 3 shown.

[0082] See also Figure 1 , Figure 3 to Figure 6 Optionally, in some embodiments, when the wind driving component 60 rotates and drives the blowing wheel 61 to rotate to perform the blowing function, a part of the airflow driven by the blowing wheel 61 flows from the vortex section 401 to the blowing duct 41 to away from the blowing wheel 61, and then flows to the blowing port 1122. This part of air is the blowing airflow that will flow from the blowing port 1122 to the room, and another part of the airflow driven by the blowing wheel 61 flows from the vortex section 401 into the heat dissipation duct 50 to dissipate heat and cool the irradiation component 20.

[0083] Such a setting is in line with the usage scenario when the hair-drying function is enabled: usually the user will turn on the irradiation part 20 when the hair-drying function is enabled, and when the ventilation function is started, the installation place of the air dispatching device 100 is generally unmanned, for example, the bathroom is generally unmanned, that is, the irradiation part 20 is almost never turned on when the ventilation function is enabled.

[0084] In other embodiments, there may be two heat dissipation ducts 50. When the wind-driving member 60 drives the blowing wheel 61 to rotate so that the blowing wheel 61 discharges air from the side and operates the blowing function, the blowing wheel 61 drives part of the air from the vortex section 401 into one of the heat dissipation ducts 50 to form a heat dissipation airflow. When the wind-driving member 60 drives the ventilation wheel 62 to rotate so that the ventilation wheel 62 discharges air from the side and operates the ventilation function, the ventilation wheel 62 drives part of the air from the vortex section 401 into the other heat dissipation duct 50 to form a heat dissipation airflow. Of course, only one heat dissipation duct 50 may also be provided. When the wind-driving member 60 drives the ventilation wheel 62 to rotate so that the ventilation wheel 62 discharges air from the side and operates the ventilation function, the ventilation wheel 62 drives part of the air from the vortex section 401 into the heat dissipation duct 50 to form a heat dissipation airflow.

[0085] See also Figure 1 and Figure 6 Optionally, the heat dissipation duct 50 includes a flow splitter section 51 and a heat absorption section 52. The flow splitter section 51 is formed by branching off from the vortex section 401. The heat absorption section 52 is connected to one end of the flow splitter section 51 that is relatively far from the vortex section 401. The heat absorption section 52 is thermally connected to the irradiation member 20. The inner wall of the heat absorption section 52 may be thermally connected to the heat storage part (such as the backlight part) of the irradiation member 20. The flow splitter section 51 forms the upstream of the heat dissipation duct 50, and the heat absorption section 52 forms the downstream of the heat dissipation duct 50 and serves as a place for the heat dissipation airflow to dissipate heat and cool down the irradiation member 20. The heat dissipation airflow first flows through the flow splitter section 51 and then flows through the heat absorption section 52.

[0086] Optionally, the diverter section 51 is located in the chassis 10, and the diverter section 51 and the air supply duct are arranged along the axial direction of the wind wheel. Figure 1 to Figure 6 In the illustrated embodiment, the flow splitting section 51 is branched from the upstream of the vortex section 401, the air supply duct includes the blowing duct 41 branched from the downstream of the vortex section 401, and the wind driving member 60 drives the blowing impeller 61 to rotate so that when the blowing impeller 61 discharges air from the side, the air flow in the vortex section 401 first flows through the upstream of the vortex section 401 and then flows through the downstream of the vortex section 401. A heating member 70 is provided downstream of the vortex section 401.

[0087] Optionally, in some other embodiments, the heating element 70 may also be disposed in the blowing duct 41, for example, may be disposed near the blowing port of the blowing duct 41. Figure 8 As shown, after the wind driving member 60 is started, it drives the blowing fan wheel 61 to rotate clockwise. A part of the airflow flowing clockwise around the axis of the blowing fan wheel 61 in the vortex section 401 first flows into the diversion section 51 from the upstream of the vortex section 401 to form a heat dissipation airflow, and the other part continues to flow clockwise until it flows into the blowing duct 41 from the downstream of the vortex section 401 to form a blowing airflow.

[0088] The heating element 70 may be a PTC heater or other types of heating elements 70. The heating element 70 is used to heat the blowing airflow to turn it into warm airflow. The warm airflow can heat or keep the room warm after it is blown into the room.

[0089] Optionally, the heat absorbing section 52 is bent relative to the diverter section 51, and the heat absorbing section 52 is located on the side of the wind wheel and the vortex section 401 close to the ground. In some embodiments, when the chassis 10 is arranged in place in the ceiling space, the blowing duct 41, the ventilation duct 42, the air collecting plate 11, the heat absorbing section 52, and the irradiation member 20 are arranged in sequence along the vertical direction close to the ground, and the diverter section 51 is located in the chassis 10 and is at the same or substantially the same height as the blowing duct 41.

[0090] In other embodiments, when the chassis 10 is arranged in place in the ceiling space, the ventilation duct 42, the blowing duct 41, the air collecting plate 11, the heat absorption section 52, and the irradiation element 20 are arranged in sequence along the vertical direction close to the ground, and the diversion section 51 is located in the chassis 10 and is at the same or substantially the same height as the blowing duct 41.

[0091] Optionally, no matter the blowing duct 41 is located between the ventilation duct 42 and the air collecting plate 11, or the ventilation duct 42 is located between the blowing duct 41 and the air collecting plate 11, the diverter section 51 and the blowing duct 41 are bifurcated from the vortex section 401 in the same height interval in the vertical direction of the air collecting plate 11, and the vertical direction of the air collecting plate 11 is the axial direction of the wind wheel. Specifically, the diverter section 51 and the blowing duct 41 are both in the axial dimension interval of the blowing wheel 61 in the vertical direction of the air collecting plate 11. With such a configuration, when the wind driving member 60 runs and drives the blowing wheel 61 to rotate so that the blowing wheel 61 discharges air from the side, part of the gas will inevitably be driven into the heat dissipation duct 50 by the blowing wheel 61 to form a heat dissipation airflow.

[0092] Optionally, the diverter section 51 is formed on the side of the air collecting plate 11 away from the irradiation member 20, the heat absorption section 52 is formed in the interval space between the irradiation member 20 and the air collecting plate 11, and the heat absorption section 52 is thermally connected to the irradiation member 20. When the box body 12 is arranged in place in the ceiling space, the diverter section 51 is higher than the heat absorption section 52 in the vertical direction, and the air collecting plate 11 is further provided with a guide outlet 1121, which penetrates the two sides of the air collecting plate 11 to connect the diverter section 51 and the heat absorption section 52.

[0093] See also Figure 1The heat dissipation duct 50 further includes a guide portion 53 disposed between the diverter section 51 and the heat absorption section 52. The guide portion 53 is used to provide a steering assist to the heat dissipation airflow flowing out of the diverter section 51 to guide the heat dissipation airflow to flow smoothly into the heat absorption section 52. The guide portion 53 includes a starting end 531 and a leading end 532. The starting end 531 is a portion where the guide portion 53 makes initial contact with the heat dissipation airflow just flowing out of the diverter section 51 and guides the heat dissipation airflow. The leading end 532 is a portion where the heat dissipation airflow leaves the guide portion 53. The starting end 531 is located at one end of the guide portion 53 close to the diverter section 51, and the leading end 532 is located at one end of the guide portion 53 close to the heat absorption section 52 and away from the diverter section 51. When the chassis 10 is arranged in place in the ceiling space, the distance from the guide portion 53 to the ground tends to decrease from the starting end 531 to the leading end 532.

[0094] Optionally, the air guide 53 is arranged in the chassis 10, and the air collecting plate 11 is arranged horizontally when the box body 12 is arranged in place in the ceiling space, and the distance from the air guide 53 to the side of the air collecting plate 11 facing away from the ground gradually decreases from the starting end 531 to the outlet end 532. The air guide 53 can be a curved plate 30-like structure, or a flat plate-like structure that is inclined relative to the air collecting plate 11 and the vertical direction. Preferably, the outlet end 532 points to the outlet 1121 opened on the air collecting plate 11, or the outlet end 532 is adapted to the opening edge of the outlet 1121.

[0095] In some embodiments, the air duct group 40 also includes an air flow separator 45 located between the air supply duct and the diversion section 51. The air supply duct and the diversion section 51 are arranged in sequence along the axis of the wind wheel. The air flow separator 45 can be a flat plate structure perpendicular to the axis of the wind wheel. The air supply duct and the diversion section 51 are respectively formed on both sides of the air flow separator 45.

[0096] See also Figure 1 and Figure 5 The airflow separator 45 connects the guide piece 43 and the special-shaped piece and is parallel to the air collecting plate 11. The airflow separator 45 is located in the chassis 10 and is provided with a through hole for the wind wheel to pass through. The diversion section 51 is formed on the side of the airflow separator 45 away from the air collecting plate 11. The blowing duct 41 and the ventilation duct 42 are formed on the other side of the airflow separator 45 close to the air collecting plate 11. The distance from the blowing duct 41 to the air collecting plate 11 is greater than the distance from the ventilation duct 42 to the air collecting plate 11.

[0097] In other embodiments, the airflow divider 45 may not necessarily be parallel to the air collecting plate 11. For example, the airflow divider 45 may be perpendicular to the air collecting plate 11, the diversion section 51 is formed on one side of the airflow divider 45, and the blowing duct 41 and the ventilation duct 42 are formed on the other side of the airflow divider 45.

[0098] In some embodiments, the fuselage further includes a heat collecting cover 80 located between the irradiating member 20 and the wind collecting plate 11. The heat collecting cover 80 can be covered on the backlight portion. The space between the heat collecting cover 80 and the backlight portion forms a heat absorbing section 52. The heat absorbing section 52 penetrates the heat collecting cover 80 to form an inlet 81 and an outlet 82. The inlet 81 is used to connect to the outlet 1121 to receive the heat dissipation airflow from the diversion section 51, and the outlet 82 is used to discharge the heat dissipation airflow that has absorbed heat.

[0099] Optionally, in some embodiments, the air inlet of the blowing wheel 61 and / or the air inlet of the ventilation wheel 62 is connected to the outflow port 82, and the heat-absorbing heat dissipating airflow discharged from the heat absorption section 52 can be sucked into the air duct group 40 again by the wind driving member 60. In other embodiments, the outflow port 82 is connected to the outside of the fuselage.

[0100] See also Figure 1 and Figure 6 When the box body 12 is arranged in place in the ceiling space, the chassis 10, the heat collecting cover 80, the heat absorbing section 52 and the irradiating element 20 are stacked in sequence in the direction close to the ground. The heat collecting cover 80 makes the heat generated by the irradiating element 20 when emitting light accumulate between the heat collecting cover 80 and the backlight part, preventing the heat from being transferred and diffused into the chassis 10 or other components. The heat dissipation airflow flowing into the heat absorbing section 52 can drive out the accumulated heat in the heat absorbing section 52, and can also conduct convection heat transfer with the inner wall surface of the heat absorbing section 52. The heat of the inner wall surface of the heat absorbing section 52 is conducted from the irradiating element 20, so the heat of the irradiating element 20 can be taken away by convection heat transfer and heat conduction.

[0101] Figure 1 to Figure 6 The air dispatching device 100 shown has a body structure similar to a rectangular parallelepiped. When the box 12 is arranged in place in the ceiling space, the vortex section 401, the air collecting plate 11, the heat collecting cover 80, the heat absorbing section 52, and the irradiation element 20 are stacked in sequence in the vertical direction. Compared with arranging the heat dissipation duct 50 and the irradiation element 20 adjacent to each other in the horizontal direction, Figure 1 to Figure 6 The overall structure of the air handling device 100 shown is not too flat, which is convenient for transportation, packaging and installation.

[0102] Optionally, in some embodiments, the outlet end 532 of the air guide 53 points to the outlet 1121 and the inlet 81, and the figure of the outlet end 532 being projected on the plane parallel to the air collecting plate 11 is entirely or partially located in the figure of the outlet 1121 being projected on the plane, and the figure of the outlet end 532 being projected on the plane parallel to the air collecting plate 11 is entirely or partially located in the figure of the inlet 81 being projected on the plane. With such a configuration, the heat dissipating airflow leaving the diversion section 51 can obtain a flow velocity close to the outlet 1121 and the inlet 81 under the guidance of the air guide 53, so that the heat dissipating airflow can enter the heat absorbing section 52 in sufficient quantity, with low loss and smoothly.

[0103] See also Figure 7 In some embodiments, the fuselage further includes a hollow blocking ring 83 , one end of which is connected to the heat absorption section 52 , and the other end of which is connected to the chassis 10 and communicates with the diversion section 51 in the box body 12 . Figure 1 , Figure 6-7 In the illustrated embodiment, the obstruction ring 83 is convexly disposed on the side of the heat collecting cover 80 away from the irradiation member 20 and close to the air collecting plate 11, one end of the obstruction ring 83 is connected to the heat absorbing section 52 through the inlet 81, and the other end of the obstruction ring 83 is connected to the air collecting plate 11 so that the diversion section 51 in the box body 12 is connected to the hollow through hole of the obstruction ring 83. Optionally, the obstruction ring 83 is integrally formed with the heat collecting cover 80, and the obstruction ring 83 can be either a circular ring structure or a polygonal prism-shaped hollow structure.

[0104] Optionally, one end of the obstruction ring 83 protruding from the heat collecting cover 80 is inserted through the outlet 1121 and then extends into the chassis 10 to communicate with the diversion section 51. In the case where a guide portion 53 is provided in the chassis 10, the outlet end 532 of the guide portion 53 can point to the hollow through hole of the obstruction ring 83, or can be matched with the edge of the hollow through hole on the obstruction ring 83, so that the heat dissipation airflow can enter the hollow through hole of the obstruction ring 83 immediately after leaving the outlet end 532, and then smoothly flow into the heat absorption section 52; in the case where the guide portion 53 is not provided in the chassis 10, the hollow through hole of the obstruction ring 83 is directly connected to the diversion section 51, so that the heat dissipation airflow can be directly received. Preferably, the outer peripheral wall of the obstruction ring 83 is fixedly matched with the inner wall surface of the outlet 1121 to form a certain degree of sealing fit.

[0105] When the wind driving component 60 is in operation, the air outside the fuselage flows from the gap between the irradiating component 20 and the wind collecting plate 11 to the wind collecting port 111 to flow into the chassis 10. The air can be blocked by the blocking ring 83 between the air and the heat dissipation airflow, thereby avoiding conflict and disturbance between the air and the heat dissipation airflow, ensuring that the heat dissipation airflow can flow smoothly from the diversion section 51 into the heat absorption section 52, and also ensuring that the air outside the fuselage can flow smoothly into the chassis 10 and be obtained by the wind driving component 60.

[0106] In some embodiments not shown in the figures, the air supply duct only has a blowing duct branched off from the vortex section 401, and the wind wheel only has a blowing wheel. After the wind driving part is started, the blowing wheel drives a part of the air from the vortex section into the blowing duct, and the other part of the air is driven from the vortex section into the heat dissipation duct.

[0107] In some embodiments not shown in the figures, the air supply duct only has a ventilation duct branched off from the vortex section 401, and the wind wheel only has a ventilation wind wheel. After the wind driving component is started, the ventilation wind wheel drives a part of the air from the vortex section into the ventilation duct, and the other part of the air is driven from the vortex section into the heat dissipation duct.

[0108] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention.
