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 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 a fuselage, an air drive component and an irradiation component, the fuselage is formed with an air drive flow channel and a heat dissipation flow channel, the air outlet of the air drive component is connected to the air drive flow channel, the irradiation component and the heat dissipation flow channel form a heat-conducting connection, an exhaust fork and an air cooling fork are provided at the end of the air drive flow channel away from the air outlet, the exhaust fork is connected to the outside of the fuselage, and the air cooling fork is connected to the heat dissipation flow channel.

[0006] After the wind driving component is started, the airflow in the wind driving channel is divided into at least two tributaries through the exhaust fork and the air cooling fork. The tributary airflow flowing out of the exhaust fork forms an exhaust airflow blowing to the outside of the fuselage, and the tributary airflow flowing out of the air cooling fork enters the heat dissipation duct to form a heat dissipation airflow, and convective heat transfer occurs with the inner wall of the heat dissipation duct to dissipate heat and cool the irradiated component. The above exhaust airflow and heat dissipation airflow are both formed by the wind driving component to accelerate the air. There is no need to add an additional cooling fan to obtain the cooling airflow, thus avoiding the increase in volume and weight caused by the cooling fan. Compared with similar products equipped with existing cooling fans, the air dispatching device of the utility model has a simpler structure.

[0007] In one embodiment, the heat dissipation air duct includes an inlet and an outlet, wherein the inlet is connected to the air cooling fork, and the outlet is connected to the air inlet of the wind driving member. With such a configuration, the heat dissipation airflow can flow into the air inlet of the wind driving member after flowing out of the outlet, and thus be driven and accelerated again by the wind driving member, thereby realizing the circulation of the heat dissipation airflow in the wind driving flow duct and the heat dissipation air duct, which is conducive to maintaining the flow rate and wind force stability of the exhaust airflow flowing out of the exhaust fork.

[0008] In one embodiment, the heat dissipation air duct includes an inlet and an outlet, wherein the inlet is connected to the air cooling fork, and the outlet is connected to the outside of the fuselage. In this way, the heat dissipation airflow can be discharged from the fuselage after flowing out of the outlet to avoid the heat in the heat dissipation airflow from accumulating in the fuselage, thereby avoiding the interference and threat of the accumulated heat to other components in the fuselage.

[0009] In one embodiment, the fuselage is provided with a movable switching member, the exhaust branch includes a blowing branch and a ventilation branch respectively located on both sides of the switching member, the air cooling branch includes a first air cooling port connected to the heat dissipation air duct, the switching member can reciprocate to approach one of the blowing branch and the ventilation branch, so that one of the blowing branch and the ventilation branch that is relatively close to the switching member is blocked from the wind-driving flow channel, and the other is connected to the wind-driving flow channel, the first air cooling port is located on the side of the switching member away from the ventilation branch, and can be connected with the blowing branch or blocked from the wind-driving flow channel. With such arrangement, the air dispatching functions of the air dispatching device include a blowing function and a ventilation function. When the switching component blocks the wind-driving flow channel and the ventilation branch, the wind-driving flow channel is connected to the blowing branch and the wind-driving flow channel is connected to the first air cooling port. At this time, the air dispatching device performs the blowing function and can generate a heat dissipation airflow to dissipate heat and cool the irradiated component. When the switching component blocks the wind-driving flow channel and the blowing branch, the wind-driving flow channel is connected to the ventilation branch. At this time, the air dispatching device performs the ventilation function.

[0010] In one embodiment, the air cooling fork also includes a second air cooling port connected to the heat dissipation air duct, the second air cooling port is located on the side of the switching member away from the blowing fork, and can be connected to the ventilation fork or blocked from the wind-driving channel. In this way, the air dispatching device can generate a heat dissipation airflow while performing the ventilation function to dissipate heat and cool the irradiated member.

[0011] In one embodiment, the fuselage includes an obstruction ring connected to the heat dissipation air duct and a chassis accommodating the wind-expelling member, the chassis is formed with a wind-expelling flow duct and is provided with an air collecting port to connect to the air inlet of the wind-expelling member, and the obstruction ring is connected to the chassis and connected to the air-cooling fork. Such an arrangement can ensure that the heat dissipation airflow flowing out of the air-cooling fork can flow smoothly into the heat dissipation air duct through the obstruction ring without being disturbed and impacted by other ambient airflows, especially when the wind-expelling member is activated so that the air outside the fuselage enters the air inlet through the air collecting port, the obstruction ring can block the heat dissipation airflow from the air flowing to the air collecting port to avoid poor airflow between the two.

[0012] In one embodiment, the fuselage includes a heat collecting cover stacked on the chassis and provided with an obstruction ring, and the heat dissipation duct is located between the heat collecting cover and the irradiation member and passes through the heat collecting cover to form an inlet connected to the obstruction ring. With this arrangement, it is easier to connect the obstruction ring to the chassis and connect the air-cooling bifurcation. The obstruction ring is connected to the heat dissipation duct in advance, and the heat collecting cover and the chassis only need to be stacked and assembled to connect the obstruction ring to the chassis and connect the air-cooling bifurcation, thereby reducing the number of assembly steps.

[0013] In one embodiment, the irradiation member includes a light-emitting portion facing the room and a backlight portion opposite to the light-emitting portion, a heat collecting cover is provided on the backlight portion, and a heat dissipation duct is provided between the heat collecting cover and the backlight portion. With such a configuration, the heat generated by the irradiation member during operation can be basically stored between the heat collecting cover and the backlight portion, and after the heat dissipation airflow flows into the heat dissipation duct, the stored heat can be concentrated and driven away from the heat dissipation duct, and the heat will not diffuse and transfer to other components in the body.

[0014] In one embodiment, the exhaust fork includes a blowing fork connected to the room, and the air dispatching device also includes a heating element arranged at the blowing fork. In this way, the exhaust airflow flowing out of the blowing fork forms a blowing airflow, and the blowing airflow can be heated by the heating element to provide a heating or heat preservation function for the room, and the heating element basically does not increase the temperature of the heat dissipation airflow, ensuring that the temperature of the heat dissipation airflow flowing into the heat dissipation air duct is relatively low to meet the heat dissipation and cooling requirements of the irradiation element.

[0015] In one embodiment, the fuselage further includes a heat insulating member, which divides the end of the air-driving flow channel into at least two sub-ends, and the exhaust fork and the air-cooling fork are respectively formed by the two sub-ends, and the two are respectively located on both sides of the heat insulating member. In this way, the heat insulating member pre-divides the airflow to the end of the air-driving flow channel to facilitate the exhaust airflow and the heat dissipation airflow to flow out through the exhaust fork and the air-cooling fork respectively, and can also block the heat of the exhaust airflow from transferring to the heat dissipation airflow, thereby avoiding the temperature rise of the heat dissipation airflow.

[0016] In one embodiment, the fuselage further includes a heat insulating member, which divides the end of the wind-driving channel into at least two sub-ends, and the exhaust fork and the air-cooling fork are formed by the two sub-ends, respectively, and the two are located on both sides of the heat insulating member, and the heat insulating member has a heat insulating cavity inside. In this arrangement, the heat insulating cavity can further enhance the heat insulating capacity of the heat insulating member, thereby better preventing the heat of the exhaust airflow from transferring to the heat dissipation airflow.

[0017] In one embodiment, the heat dissipation duct is arranged on the side of the wind-driving flow channel close to the ground, and a heat dissipation guide is arranged in the fuselage, and the heat dissipation guide includes a starting end close to the air-cooling fork and an outlet end close to the heat dissipation duct, and the distance from the heat dissipation guide to the ground decreases from the starting end to the outlet end. In this way, the wind-driving flow channel and the heat dissipation duct are arranged in a stacked manner in the fuselage, which avoids the overall structure of the air dispatching device from being too flat, making the overall structure of the air dispatching device more compact and the use of the fuselage space more reasonable. The heat dissipation guide can provide steering assistance and guidance for the heat dissipation airflow flowing out of the wind-driving flow channel so that the heat dissipation airflow can flow into the heat dissipation duct smoothly and with low resistance after turning.

[0018] In one embodiment, the irradiation member is arranged on the side of the wind-driving member close to the ground, including a light board and a light-emitting body arranged on the side of the light board close to the ground, and the side of the light board facing away from the light-emitting body is thermally connected to the heat dissipation duct. In this way, the wind-driving flow duct, the heat dissipation duct and the irradiation member are arranged in a stacked manner in sequence, and neither the wind-driving flow duct nor the heat dissipation duct will affect the light emission of the irradiation member into the room, which can avoid the overall structure of the air dispatching device from being too flat, and further make the overall structure of the air dispatching device compact.

[0019] In one embodiment, the heat dissipation duct penetrates the heat collecting cover to form an outlet, and at least a portion of the outlet faces the air inlet of the wind-driving member. With this arrangement, the heat dissipation airflow can flow into the air inlet of the wind-driving member after flowing out of the outlet, and is then driven and accelerated again by the wind-driving member, and the loss of the heat dissipation airflow due to the failure to flow into the air inlet is reduced, thereby realizing the circulation of the heat dissipation airflow in the wind-driving flow duct and the heat dissipation air duct, which is conducive to maintaining the flow rate and wind force stability of the exhaust airflow flowing out of the exhaust fork.

[0029] 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.

[0030] 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.

[0031] The utility model provides an air regulation device 100 equipped with a wind-repelling member 20 and an irradiating member 60, which has both air regulation function and light irradiation function. The air regulation function is realized based on the wind-repelling member 20, including the blowing function of conveying air indoors and the ventilation function of transferring indoor air to outdoors; the light irradiation function is realized based on the light emitted by the irradiating member 60, and the irradiating member 60 can be a lighting lamp that provides conventional lighting function, or an atmosphere lamp that adjusts the indoor color tone, or a maintenance lamp with beauty and recuperation function, which is also called a beauty lamp, which radiates energy to human skin by emitting maintenance light to perform skin care treatment.

[0032] The air dispatching device 100 of the utility model can be used in a bathroom or in other indoor places. When the air dispatching device 100 is a heater installed in a bathroom, at least a part of the air dispatching device 100 can be arranged in the ceiling space between the bathroom ceiling and the ceiling plate. It can be understood that the air dispatching device 100 can also be suspended relative to the ground by other installation methods, and is not limited to being installed between the ceiling and the ceiling plate.

[0033] The air conditioning device 100 of the utility model can be a heater equipped with an irradiation element 60, a ventilation fan equipped with an irradiation element 60, or a fresh air blower equipped with an irradiation element 60. For the convenience of description, the air conditioning device 100 is introduced below by taking a heater equipped with an irradiation element 60 as an example.

[0034] The wind driving member 20 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 wind driving member 20 includes the blowing airflow flowing into the room; when the air dispatching device 100 operates the ventilation function, the airflow driven by the wind driving member 20 includes the exhaust airflow flowing outdoors. In some embodiments, the air dispatching device 100 is compatible with the blowing function and the ventilation function, and in other embodiments, the air dispatching device 100 has one of the blowing function and the ventilation function.

[0035] According to the type of the irradiation element 60 and the type of light emitted, 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, that is, the irradiation element 60 includes an illuminating lamp, an atmosphere lamp, and a maintenance lamp. In other embodiments, the irradiation element 60 includes any one or any two of the illuminating lamp, the atmosphere lamp, and the maintenance lamp, and 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.

[0036] The air conditioning device 100 of the present invention further comprises a body 10, and the wind driving member 20 and the irradiating member 60 are both mounted on the body 10. Figure 1 and Figure 3 In some embodiments, the body 10 includes a chassis 13 accommodating the wind-repelling member 20 and a panel 18 on which the irradiating member 60 is installed. The chassis 13 includes a box body 131 with an opening for accommodating the wind-repelling member 20, and a wind collecting plate 132 covering the opening of the box body 131. At least a portion of the box body 131 can be installed in the ceiling space between the ceiling and the ceiling panel. When the box body 131 is installed in place in the ceiling space, the wind collecting plate 132 is located on the side of the box body 131 close to the ground and closes the opening facing the ground.

[0037] Furthermore, the irradiation member 60 and the panel 18 are arranged on the side of the wind collecting plate 132 away from the box 131, and the light-emitting part of the irradiation member 60 faces the room and the ground when the box 131 is installed in place in the ceiling space, and the side of the panel 18 away from the chassis 13 faces the room and the ground when the box 131 is installed in place in the ceiling space. Preferably, the irradiation member 60 and the panel 18 are spliced ​​and installed to form a panel assembly in the shape of a plate, and the box 131, the wind collecting plate 132 and the panel assembly are installed in a stacked manner in the vertical direction.

[0038] Optional, Figure 1 and Figure 3 The air dispatching device 100 shown has a blowing function, and the air collecting plate 132 is provided with an air collecting port 1321 and a first outlet 1322. The air collecting port 1321 is connected to the air inlet of the wind driving component 20. After the wind driving component 20 is started, the air in the room can flow from the air collecting port 1321 into the chassis 13 and then into the air inlet. A part of the airflow driven by the wind driving component 20 is defined as exhaust airflow, and at least a part of the exhaust airflow flows out of the chassis 13 from the first outlet 1322 and flows into the room, so the part of the exhaust airflow flowing out from the first outlet 1322 forms a blowing airflow.

[0039] Specifically, see Figure 1 and Figure 3 The panel 18 is provided with an air outlet window 182 and an air inlet 181, the air outlet window 182 penetrates the side of the panel 18 away from the chassis 13 and toward the indoor room, and the air outlet window 182 is connected to the first outlet 1322, and the blowing air flow is blown into the indoor room through the first outlet 1322 and the air outlet window 182 in sequence, and the air inlet 181 penetrates the side of the panel 18 away from the chassis 13 and toward the indoor room, and a gap connected to the air inlet 181 is provided between the panel 18 and the air collecting plate 132. After the air driving member 20 drives, the air in the room flows into the air collecting port 1321 through the air inlet 181 and the gap in sequence.

[0040] It can be understood that in other embodiments, the air collecting port 1321 and the first outlet 1322 can also be opened at other positions of the fuselage 10 and are not limited to being opened at the air collecting plate 132. The air outlet window 182 and the air intake port 181 can also be opened at other positions of the fuselage 10 and are not limited to being opened at the panel 18. The air intake port 181 does not have to be formed in a manner of penetrating both sides of the panel 18. In some embodiments, the air intake port 181 is formed by the gap between the panel 18 and the air collecting plate 132.

[0041] Specifically, in some embodiments, the irradiation member 60 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 60. 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 60. When the box 131 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 and the air collecting plate 132 are spaced apart to prevent the backlight portion from burning the chassis 13 and the components in the chassis 13, and the spacing between the backlight portion and the air collecting plate 132 is conducive to the heat dissipation of the backlight portion.

[0042] Optionally, the illuminating element 60 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 60 .

[0043] In some embodiments, the panel 18 can also be omitted. After the panel 18 is omitted, the irradiating member 60 is separately installed on the side of the wind collecting plate 132 away from the box body 131, and the irradiating member 60 and the wind collecting plate 132 can be spaced apart. The irradiating member 60 and the wind collecting plate 132 are spaced apart to prevent the irradiating member 60 from burning the chassis 13 and components inside the chassis 13, and the spacing between the irradiating member 60 and the wind collecting plate 132 is conducive to the heat dissipation of the irradiating member 60, and also provides space for arranging a heat sink.

[0044] See also Figure 1 In some embodiments, the wind driving member 20 includes a centrifugal wind driving portion 21 disposed in the chassis 13, the centrifugal wind driving portion 21 includes a centrifugal wind wheel, and when the chassis 13 is arranged in place in the ceiling space, the axis of the centrifugal wind wheel extends vertically and is perpendicular to the wind collecting plate 132, the air inlet of the wind driving member 20 includes an end of the centrifugal wind driving portion 21 close to the wind collecting plate 132, the air collecting port 1321 is arranged opposite to the end of the centrifugal wind driving portion 21 close to the wind collecting plate 132, and the air outlet of the wind driving member 20 includes the peripheral side of the centrifugal wind driving portion 21, specifically, the peripheral side of the centrifugal wind wheel is provided with a plurality of spaced blades. In other embodiments, the centrifugal wind driving portion 21 can also be replaced by other wind driving members 20.

[0045] In the utility model, the fuselage 10 is formed with an air drive channel 11 and a heat dissipation channel 12. The air outlet of the air drive member 20 is connected to the air drive channel 11, so that when the air drive member 20 is in operation, air flows out from the air outlet and flows along the air drive channel 11. A thermal connection is formed between the inner wall of the heat dissipation channel 12 and the irradiation member 60. Specifically, the inner wall of the heat dissipation channel 12 and the heat storage part of the irradiation member 60 are thermally connected. An exhaust fork 111 and an air cooling fork 112 are provided at the end of the air drive channel 11 away from the air outlet of the air drive member 20. The exhaust fork 111 is connected to the outside of the fuselage 10, and the air cooling fork 112 is connected to the heat dissipation channel 12.

[0046] After the wind driving component 20 is driven, the air flowing along the wind driving channel 11 is divided into at least two airflows through the exhaust branch 111 and the air cooling branch 112, namely the exhaust airflow and the heat dissipation airflow. The exhaust airflow flows out from the exhaust branch 111 and blows to the outside of the fuselage 10, and the heat dissipation airflow flows out from the air cooling branch 112 and enters the heat dissipation duct 12 to dissipate heat and cool the irradiation component 60. The heat of the irradiation component 60 is conducted to the inner wall of the heat dissipation duct 12, and convective heat transfer is carried out between the heat dissipation airflow and the inner wall of the heat dissipation duct 12, thereby the heat of the irradiation component 60 is taken away by the heat dissipation airflow, and the accumulated heat conducted from the irradiation component 60 to the heat dissipation duct 12 is also taken away by the heat dissipation airflow.

[0047] Specifically, the heat dissipation duct 12 includes an inlet 121 and an outlet 122. The inlet 121 is connected to the air cooling fork 112 so as to receive the heat dissipation airflow from the air cooling fork 112. The outlet 122 is used to discharge the heat dissipation airflow that has absorbed heat from the heat dissipation duct 12. In some embodiments, the outlet 122 is connected to the air inlet of the wind driving member 20, and the heat dissipation airflow discharged from the heat dissipation duct 12 can be driven and accelerated again by the wind driving member 20, and this part of the air continues to flow along the wind driving channel 11, so that a part of the airflow circulates in the heat dissipation duct 12 and the wind driving channel 11. In other embodiments, the outlet 122 is connected to the outside of the fuselage 10, and the heat dissipation airflow discharged from the heat dissipation duct 12 from the outlet 122 can eventually flow out of the fuselage 10.

[0048] Further, see Figure 1-2 The air dispatching device 100 also includes a heating element 40 disposed at the exhaust fork 111. The heating element 40 may be a PTC heater or other types of heating elements 40. The heating element 40 is used to heat the air so that the exhaust airflow blown out from the exhaust fork 111 becomes a warm airflow. When the warm airflow is delivered to the room, the room temperature can be raised or kept warm. It should be noted that the heating element 40 needs to be disposed at the end of the wind-expelling flow channel 11. Otherwise, if the heating element 40 is closer to the air outlet of the wind-expelling element 20, the heating element 40 will heat the air used to form the heat dissipation airflow, and the heated heat dissipation airflow is obviously not conducive to the heat dissipation of the irradiation element 60.

[0049] Specifically, see Figure 1-2 , Figure 4 , Figure 6-7 The exhaust fork 111 includes a blowing fork 1111, which is connected to the first outlet 1322 opened on the air collecting plate 132, and the heating element 40 is arranged at the blowing fork 1111, so that the wind-driving channel 11, the blowing fork 1111, the first outlet 1322, and the air outlet window 182 are connected to form a passage for a part of the exhaust air flow to flow to the indoor space, so the part of the exhaust air flow that is sequentially transported to the indoor space through the blowing fork 1111, the first outlet 1322, and the air outlet window 182 becomes the blowing air flow. Of course, in other embodiments, the blowing fork 1111 can also penetrate other positions of the fuselage 10 to connect to the indoor space, without having to connect to the indoor space in a way of penetrating the panel 18.

[0050] Optional, in Figure 1-2 Based on the illustrated embodiment, the heating element 40 arranged at the blowing fork 1111 can also be transferred to the first outlet 1322 or the outlet window 182, or a heating element 40 can be further added in at least one of the first outlet 1322 and the outlet window 182 to improve the heating effect of the blowing airflow.

[0051] Specifically, see Figure 1-2 The air-driving channel 11 is formed in the chassis 13, and the peripheral side of the centrifugal air-driving part 21 has a plurality of spaced-apart blades, and an exhaust gap connected to the air inlet of the centrifugal air-driving part 21 is formed between any two blades, and a plurality of exhaust gaps are arranged along the peripheral side of the centrifugal air-driving part 21 and are connected to the air-driving channel 11. The fuselage 10 also includes a heat insulating member 50 arranged in the chassis 13, and the heat insulating member 50 is located at the end of the air-driving channel 11 relatively away from the peripheral side of the centrifugal air-driving part 21, and divides the end of the air-driving channel 11 into at least two sub-ends, and the two sub-ends form an exhaust fork 111 and an air-cooling fork 112 respectively located on both sides of the heat insulating member 50.

[0052] See also Figures 4 to 8 The air cooling fork 112 includes a first air cooling port 1121 connected to the heat dissipation air duct 12. The first air cooling port 1121 and the air blowing fork 1111 are respectively opened on both sides of the heat insulating member 50. The heat insulating member 50 is arranged in this way to prevent the heat generated by the heating member 40 located at the air blowing fork 1111 from being transferred to the first air cooling port 1121, thereby preventing the heat dissipation airflow from being heated by the heating member 40 and thus weakening the heat dissipation and cooling effect. In order to improve the heat blocking effect of the heat insulating member 50, the heat insulating member 50 is made of a material with low thermal conductivity. Figure 7 An insulating cavity 51 may be provided inside the insulating member 50. The insulating cavity 51 has a low heat transfer characteristic and may be a vacuum or filled with gas.

[0053] In some embodiments, the exhaust fork 111 also includes a ventilation fork 1112 for connecting to the outdoors. The ventilation fork 1112 is arranged so that at least a portion of the airflow in the wind-driving flow channel 11 can be discharged to the outdoors through the ventilation fork 1112, thereby removing the waste air in the room. Therefore, the portion of the exhaust airflow that is transported to the outdoors through the ventilation fork 1112 becomes the waste airflow. Figure 1-2 Optionally, the ventilation fork 1112 is provided in the box 131. Figures 1 to 8 In the illustrated embodiment, the exhaust branch 111 includes a blowing branch 1111 and a ventilation branch 1112 . It is understandable that in other embodiments, the exhaust branch 111 may be only one of the blowing branch 1111 and the ventilation branch 1112 .

[0054] Further, Figures 1 to 8 The air dispatching device 100 shown also includes a switching member 30 movably arranged on the fuselage 10, and the switching member 30 includes a damper 31 and a switching driving unit 32 connected to the damper 31, and the switching driving unit 32 is fixedly installed on the fuselage 10, and is used to drive the damper 31 to move relative to the fuselage 10. The blowing fork 1111 and the ventilation fork 1112 are respectively located on both sides of the damper 31, and the first air cooling port 1121 and the blowing fork 1111 are located on the same side of the damper 31, that is, both are located on the side of the damper 31 away from the ventilation fork 1112. The switching member 30 can make the air dispatching device 100 selectively operate the blowing function and the ventilation function through reciprocating movement, that is, Figures 1 to 8 The air dispatching device 100 shown is compatible with the blowing function and the ventilation function, but does not have the property of operating the blowing function and the ventilation function at the same time.

[0055] See also Figure 1 The switch drive unit 32 is fixedly mounted on the air collecting plate 132. The damper 31 rotates around an axis perpendicular to the air collecting plate 132 under the drive of the switch drive unit 32. The heat insulating member 50 between the blowing fork 1111 and the first air cooling port 1121 is located on the side of the damper 31 away from the inner wall of the box body 131 where the ventilation fork 1112 is opened. Figure 2 , Figure 4 , Figure 6-7 When the switch driving unit 32 drives the damper 31 to the first position, one end of the damper 31 abuts against the inner wall of the box body 131 on which the ventilation fork 1112 is opened, so that the ventilation fork 1112 and the air-driving channel 11 are blocked by the damper 31, and the blowing fork 1111 is connected to the air-driving channel 11, and at this time, the first air-cooling port 1121 is connected to the air-driving channel 11;

[0056] See also Figure 5 and Figure 8When the damper 31 is driven to the second position, one end of the damper 31 abuts against the volute tongue 113 of the wind-driving channel 11, and the volute tongue 113 is arranged opposite to the inner wall of the box body 131 on which a ventilation fork 1112 is provided. Therefore, the blowing fork 1111 and the wind-driving channel 11 are blocked by the damper 31, and the first air cooling port 1121 and the wind-driving channel 11 are blocked by the damper 31, and at this time, the ventilation fork 1112 is connected to the wind-driving channel 11.

[0057] Further, see Figure 8 , compared to Figure 1 to Figure 7 The air dispatching device 100 shown, Figure 8 In the air dispatching device 100 shown, the air cooling fork 112 also includes a second air cooling port 1122 connected to the heat dissipation air duct 12. The second air cooling port 1122 and the ventilation fork 1112 are both located on the side of the damper 31 away from the blowing fork 1111. When the damper 31 is driven to the first position, the second air cooling port 1122 and the air driving channel 11 are blocked by the damper 31. When the damper 31 is driven to the first position, the second air cooling port 1122 and the air driving channel 11 are blocked by the damper 31. Figure 8 In the second posture shown, the second air cooling port 1122 is connected to the wind driving channel 11 .

[0058] So set up, Figure 8 The air dispatching device 100 shown can ensure that the wind-driving channel 11 is connected to the heat dissipating air channel 12 through one of the first air-cooling port 1121 and the second air-cooling port 1122 regardless of whether it is running the blowing function or the ventilation function, thereby forming a heat dissipating airflow flowing into the heat dissipating air channel 12.

[0059] In some embodiments, the switching component 30 can also be omitted. After omitting the switching component 30, the air scheduling function is only one of the blowing function and the ventilation function, and the exhaust branch 111 is only one of the blowing branch 1111 and the ventilation branch 1112. When the exhaust branch 111 is the blowing branch 1111, the air scheduling function is the blowing function, and when the exhaust branch 111 is the ventilation branch 1112, the air scheduling function is the ventilation function.

[0060] In some embodiments, the heat dissipation duct 12 is formed on the side of the wind-driving duct 11 close to the ground. When the chassis 13 is arranged in place in the ceiling space, the height of the heat dissipation duct 12 is lower than that of the wind-driving duct 11. In order to allow the heat dissipation airflow flowing out of the air-cooling fork 112 to better play a heat dissipation role and to allow sufficient convection heat transfer between the heat dissipation airflow and the inner wall of the heat dissipation duct 12, a heat dissipation guide 16 is further provided in the fuselage 10. The heat dissipation guide 16 is used to assist the heat dissipation airflow that has just flowed out of the air-cooling fork 112 to change the flow trajectory and flow direction of the heat dissipation airflow, and guide the heat dissipation airflow flowing out of the air-cooling fork 112 to flow into the heat dissipation duct 12 in sufficient quantity and smoothly.

[0061] See also Figure 1-2The heat dissipation guide 16 includes a starting end 161 and an outlet end 162. The starting end 161 is the part where the heat dissipation guide 16 makes initial contact with the heat dissipation airflow that has just flowed out of the air-cooling fork 112 and begins to assist in guiding. The outlet end 162 is the part where the heat dissipation airflow leaves the heat dissipation guide 16. The starting end 161 is located at one end of the heat dissipation guide 16 close to the air-cooling fork 112, and the outlet end 162 is located at one end of the heat dissipation guide 16 close to the heat dissipation duct 12 and away from the air-cooling fork 112. When the chassis 13 is arranged in place in the ceiling space, the distance from the heat dissipation guide 16 to the ground decreases from the starting end 161 to the outlet end 162.

[0062] Specifically, Figures 1 to 8 In the illustrated embodiment, the heat dissipation guide 16 is disposed in the chassis 13, and the air collecting plate 132 is disposed horizontally when the chassis 13 is arranged in place in the ceiling space, and the distance from the heat dissipation guide 16 to the air collecting plate 132 gradually decreases from the starting end 161 to the outlet end 162. The heat dissipation guide 16 can be a curved plate 18-shaped structure, or a flat plate-shaped structure that is inclined relative to the air collecting plate 132 and in the vertical direction.

[0063] Further, see Figure 1 and Figure 3 The irradiation member 60 is a plate-shaped member arranged on the side of the wind-driving member 20 and the chassis 13 relatively close to the ground, including a light board and a light-emitting body arranged on one side of the light board, the light-emitting body is located on the side of the light board away from the wind-driving member 20 and the chassis 13, and the side of the light board close to the wind-driving member 20 and the chassis 13 is arranged opposite to the ground to form a backlight portion of the irradiation member 60, which is also a heat-storing portion of the irradiation member 60 where heat is significantly generated. The inner wall of the heat dissipation duct 12 is thermally connected to the backlight portion, and the heat dissipation duct 12 is located between the irradiation member 60 and the wind collecting plate 132.

[0064] Specifically, see Figure 3 The body 10 also includes a heat collecting cover 14 located between the irradiation member 60 and the air collecting plate 132. The heat collecting cover 14 is covered on the backlight portion. The space between the heat collecting cover 14 and the backlight portion forms a heat dissipation duct 12. When the chassis 13 is arranged in place in the ceiling space, the chassis 13, the heat collecting cover 14, the heat dissipation duct 12 and the irradiation member 60 are stacked in sequence along the vertical direction. The heat collecting cover 14 is provided with an inlet 121 for receiving a heat dissipation airflow and an outlet 122 for discharging the heat dissipation airflow that has absorbed heat. The heat generated by the irradiation member 60 during operation can be accumulated between the heat collecting cover 14 and the backlight portion. The heat is not easily transferred and diffused into the chassis 13 or other components on the body 10. The airflow flowing into the heat dissipation duct 12 can concentrate the heat away from the heat dissipation duct 12.

[0065] Figures 1 to 8The air dispatching device 100 shown has a box-shaped body 10 that is approximately in the shape of a rectangular parallelepiped. The wind-driving duct 11, the wind-collecting plate 132, the heat-collecting cover 14, the heat-dissipating duct 12, and the irradiating element 60 are stacked in sequence in the vertical direction when the chassis 13 is arranged in place in the ceiling space. This avoids excessive flattening of the body 10 due to the arrangement of the wind-driving duct 11 and the heat-dissipating duct 12 adjacent to each other in the horizontal direction, and does not occupy too much space on the ceiling board for arranging other electrical appliances. The overall structure of the air dispatching device 100 is more compact and convenient for transportation, packaging and installation.

[0066] Optionally, in some embodiments, the wind driving member 20 includes a centrifugal wind driving portion 21, and one end of the centrifugal wind driving portion 21 close to the wind collecting plate 132 forms the wind inlet of the wind driving member 20 and is exposed through the wind collecting port 1321. The figure formed by the orthogonal projection of the flow outlet 122 on a plane parallel to the wind collecting plate 132 and the figure of the orthogonal projection of the wind collecting port 1321 on the plane have an overlapping part, so that at least a part of the flow outlet 122 is arranged opposite to the wind inlet through the wind collecting port 1321, and the heat dissipation airflow that has absorbed heat and is discharged from the flow outlet 122 can be more obtained by the wind driving member 20.

[0067] It can be understood that in other embodiments, the outlet 122 can also be connected to the indoor or outdoor environment, or the outlet 122 can also be connected to the ceiling space.

[0068] Optionally, in some embodiments, the outlet end 162 of the heat dissipation guide 16 points to the inlet 121, and the figure formed by the orthogonal projection of the outlet end 162 on a plane parallel to the air collecting plate 132 is entirely or partially located within the figure of the orthogonal projection of the inlet 121 on the plane. In this way, the heat dissipation airflow flowing along the heat dissipation guide 16 has an initial velocity of flowing toward the inlet 121 after leaving the outlet end 162, so that the heat dissipation airflow can flow into the heat dissipation air duct 12 through the inlet 121 in sufficient quantity, with low loss and smoothly.

[0069] Furthermore, in some embodiments, the body 10 further includes a hollow blocking ring 15, one end of which is connected to the heat dissipation air duct 12, and the other end of which is connected to the chassis 13 and communicates with the air cooling fork 112. Figure 5The obstruction ring 15 is protruding from the side of the heat collecting cover 14 away from the irradiation member 60. The hollow through hole of the obstruction ring 15 is connected to the inlet 121 and thus connected to the heat dissipation duct 12. The air collecting plate 132 is also provided with a second guide outlet 1323. The second guide outlet 1323 runs through the side of the air collecting plate 132 close to the irradiation member 60 and is connected to the cavity in the box body 131. Preferably, the second guide outlet 1323 is connected to the air cooling fork 112. One end of the obstruction ring 15 protruding from the heat collecting cover 14 is connected to the air collecting plate 132 so that the second guide outlet 1323 is connected to the hollow through hole of the obstruction ring 15. Optionally, the obstruction ring 15 is integrally formed with the heat collecting cover 14; the obstruction ring 15 can be either a circular ring structure or a polygonal prism-shaped hollow structure.

[0070] Optionally, one end of the blocking ring 15 protruding from the heat collecting cover 14 is inserted through the second outlet 1323 and then extends into the chassis 13 to communicate with the air cooling fork 112. Preferably, the outer peripheral wall of the blocking ring 15 is fixedly adapted to the inner wall surface of the second outlet 1323 and forms a certain sealing fit.

[0071] Optionally, the outlet end 162 of the heat dissipation guide 16 is connected to one end of the obstruction ring 15 protruding from the heat collecting cover 14; or, the outlet end 162 of the heat dissipation guide 16 points to the hollow through hole of the obstruction ring 15. In this way, the heat dissipation airflow flowing along the heat dissipation guide 16 has a speed direction toward the hollow through hole of the obstruction ring 15 when leaving the outlet end 162, so the heat dissipation airflow can flow into the heat dissipation duct 12 in a sufficient amount, with low loss, and smoothly in sequence through the hollow through hole of the obstruction ring 15, the second outlet 1323, and the inlet 121.

[0072] When the wind driving component 20 is in operation, when the air outside the fuselage 10 flows from the gap between the irradiation component 60 and the wind collecting plate 132 to the wind collecting port 1321 to flow into the air inlet of the wind driving component 20, the air can be blocked by the blocking ring 15 between 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 into the heat dissipation air duct 12, and also ensuring that the air outside the fuselage 10 can flow smoothly into the air collecting port 1321.

[0073] Optional, see Figure 1-2 In some embodiments, the fuselage 10 further includes a blowing guide portion 17, which is used to provide steering assistance and guidance for the blowing airflow, thereby changing the flow trajectory and flow direction of the blowing airflow that has just left the blowing fork 1111. Under the guidance of the blowing guide portion 17, the blowing airflow flows in a direction close to the ground, and then blows into the room through the first guide outlet 1322 and the air outlet window 182 in sequence.
