Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an air conditioning device. Background Technology

[0002] There is a type of bathroom heater that uses a ring-shaped air outlet. Compared with a straight air outlet, the ring-shaped air outlet provides a larger air outlet coverage area, and the airflow is evenly distributed along the circumference of the ring-shaped air outlet. However, the ring-shaped air outlet is not suitable for use with a louvered blade, making it difficult to adjust the airflow speed and airflow cross-section of the bathroom heater. Utility Model Content

[0003] In view of this, the present invention provides an air dispatching device that can achieve airflow speed adjustment and airflow cross-sectional size adjustment without the need for leaf adjustment.

[0004] The air control device of this utility model includes a body, a first air duct and a second air duct. An adjustable-width end air gap is formed between the first air duct and the second air duct. At least one of the first air duct and the second air duct is rotatably disposed on the body about a preset pivot and has a guide slope for forming the end air gap. Different positions on the guide slope have different inclination angles.

[0005] Compared with the prior art, the air control device of this utility model can achieve the functions of airflow speed adjustment and airflow cross-section size adjustment without the need for a flap. It achieves the purpose of adjusting the airflow cross-section size by changing the width of the end air gap. It achieves the function of adjusting the airflow speed by driving at least one of the first and second air passage components to rotate relative to the body and changing the position of the guide slope. The different tilt angles of the guide slope result in airflows with different blowing tilt angles at different positions of the guide slope. By changing the position of the guide slope, users in a specific position can be blown by airflows with different blowing tilt angles in succession, so that users can perceive changes in wind direction.

[0006] In some embodiments, the guide slope has a different tilt angle relative to the surface of the air control device, and the first or second air passage forms an adjustable floating interval with respect to the surface. The width of the end air gap corresponds to and changes in relation to the height of the floating interval.

[0007] In some embodiments, a floating unit and an airflow control component disposed on the body are also included. The floating unit is connected to the airflow control component and carries the first airflow component. The airflow control component outputs a linear displacement to adjust the floating interval between the first airflow component and the provided surface.

[0008] In some embodiments, the floating unit includes a limiting portion extending to the bottom end of the first air vent, the bottom end of the first air vent being the end of the first air vent facing away from the air control device.

[0009] In some embodiments, the second air passage is disposed around the first air passage, the outer peripheral side of the first air passage forms a first sidewall of the end air gap, the inner peripheral side of the second air passage forms a second sidewall of the end air gap, and the guide slope includes the first sidewall and / or the second sidewall.

[0010] In some embodiments, a wind direction control component is also included on the fuselage. The wind direction control component includes a transmission gear. The first air passage component is rotatably disposed around the preset rotating shaft. The inner circumference of the first air passage component is provided with internal teeth to mesh with the transmission gear. The internal teeth and the teeth of the transmission gear slide in a sliding engagement along the height direction of the floating interval.

[0011] In some embodiments, a wind direction control component is also included on the fuselage. The wind direction control component includes a transmission gear. The second air passage component is rotatably disposed around the preset rotating shaft. The outer peripheral side of the second air passage component is provided with external teeth to mesh with the transmission gear.

[0012] In some embodiments, a diversion cover is also included connecting the fuselage to the top of the first air duct, the top of the first air duct being the end of the first air duct near the surface of the air control device.

[0013] In some embodiments, a light-transmitting cover located at the bottom of the first air duct is also included, wherein the diversion cover has a light-emitting element, the air volume control element, and the floating unit on the side relatively close to the light-transmitting cover.

[0014] In some embodiments, a wind direction control component is also included on the floating unit. The first air passage component is rotatably disposed on the floating unit and connected to the wind direction control component around the preset rotating axis.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] See Figure 1 and Figure 8 This utility model provides an air control device. The specific form and application of the air control device are not limited, and it can be a bathroom heater, a fresh air unit, a ventilation fan, an indoor air conditioning unit, etc. Figure 1 and Figure 8 The air control device is a bathroom heater that combines the functions of blowing air, ventilation, heating, and lighting. The composition, structure, and principle of the air control device are described below using a bathroom heater as an example.

[0031] The air conditioning unit includes a housing 10 and a fan. The housing 10 can be installed on a suspended ceiling, indoor ceiling, or vertical wall. The housing 10 has an internal air duct 122, and the fan is installed on the housing 10 and drives airflow through the air duct 122. Figure 1 and Figure 8 As shown, the casing 10 includes a housing 12 and an air collecting plate 11. The air collecting plate 11 covers the opening of the housing 12. The fan includes a volute 121 and a rotor 13 disposed within the housing 12. The volute 121 and the rotor 13 constitute a centrifugal fan. An air duct 122 is formed inside the volute 121. The air collecting plate 11 has an air collecting port 111 and an air outlet 112 connecting the air duct 122. The side wall of the housing 12 also has an exhaust port (not labeled in the figure) connecting the outside and the air duct 122. An air damper (not labeled in the figure) is also provided inside the air duct 122, which can control the airflow in the air duct 122 to flow out from the air outlet 112 or the exhaust port. It can be understood that in other embodiments, the form of the fan is not limited to a centrifugal fan composed of a rotor 13 and a volute 121.

[0032] Optionally, when the unit 10 is installed on a suspended ceiling or indoor ceiling, the opening of the casing 12 faces the ground, and the air collecting plate 11 covering the opening of the casing 12 is horizontally arranged, with the air collecting port 111 and the exhaust port facing the ground. The surface of the suspended ceiling or indoor ceiling is the surface where the air conditioning device is installed. When the unit 10 is installed on a vertical wall, the edge of the opening of the casing 12 is located in a vertical plane, and the air collecting plate 11 covering the opening of the casing 12 is vertically arranged, with the air collecting port 111 and the exhaust port facing the room. The vertical wall is the surface where the air conditioning device is installed. Preferably, the air collecting plate 11 is parallel to the surface where the air conditioning device is installed. (See reference...) Figures 3-4 , Figures 6-7 , Figures 10-11 The direction indicated by arrow H in the figure is parallel to the surface where the air control device is located.

[0033] In some embodiments, the air control device also includes a heating element 21, which is used to heat the airflow generated when the fan is running to obtain warm air. Therefore, the heating element 21 is a necessary structure for an air control device with a warm air function.

[0034] The air control device of the present invention further includes an air outlet unit disposed on the body 10. The air outlet unit has a terminal air gap 20 communicating with the air outlet 112. The terminal air gap 20 serves as the final channel through which the airflow leaves the air control device and enters the indoor space. The airflow leaving the terminal air gap 20 and entering the indoor space is simply referred to as the outflow airflow. Optionally, the heating element 21 can be disposed in the terminal air gap 20 to keep the heating element 21 as far away as possible from important components inside the chassis 12, thereby preventing the important components inside the chassis 12 from being damaged by heat. In other embodiments, the heating element 21 can also be disposed in the air outlet 112, the air duct 122, or even at the air collection port 111.

[0035] See Figures 2-3 , Figures 9-10 The air outlet unit includes a first air passage 30 and a second air passage 40 that are relatively movable. An end air gap 20 is formed between the first air passage 30 and the second air passage 40. The width of the end air gap 20 can be adjusted as needed by moving the first air passage 30 relative to the second air passage 40. Expanding the width of the end air gap 20 increases the cross-section of the airflow passing through the end air gap 20, while narrowing the width of the end air gap 20 decreases the cross-section of the airflow passing through the end air gap 20. Changing the airflow cross-section can change the size of the area on the user's body that is blown by the airflow, so that the air control device has the function of adjustable air volume.

[0036] Since users do not remain in a specific position while using the air conditioning device, at least one of the first air duct 30 and the second air duct 40 is rotatably mounted on the body 10 around a preset pivot and has a guide slope. The guide slope forms the inner wall of the end air gap 20, guiding the airflow through the end air gap 20. The guide slope is inclined relative to the surface on which the air conditioning device is installed, so the airflow through the end air gap 20 is guided by the guide slope to obtain a flow velocity direction inclined relative to the surface. For example, when the air conditioning device is installed on a ceiling panel or indoor ceiling, and the surface is horizontal, the blown airflow blows on the user in a flow direction inclined relative to the surface and the air collecting plate 11. The user does not need to be directly below the air conditioning device, thus freeing up the user's head space and improving ease of use.

[0037] The oblique direction of the blown airflow allows for greater coverage of the user's body surface. To achieve adjustable airflow velocity and direction, thus enabling the air control device to adjust wind direction, the inclination angles relative to the surface at different positions on the guide slope are differentiated; that is, the inclination angles relative to the air collecting plate 11 and the surface differ at different positions on the guide slope. After being guided by the guide slope, the airflow forms multiple airflow bundles with inconsistent velocity directions. Different airflow bundles can cover different positions on the user's body surface, and the farthest positions they can reach are different. The angle between the guide slope and the surface is the inclination angle of the guide slope, and the angle between the velocity direction of the blown airflow and the surface is the blowing inclination angle of the blown airflow. The smaller the inclination angle at a certain position on the guide slope, the smaller the blowing inclination angle of the blown airflow passing through that position, the larger the velocity vector parallel to the surface in this blown airflow, and the farther the farthest position that the blown airflow can ultimately reach is horizontally from the air control device.

[0038] When at least one of the first air-passing component 30 and the second air-passing component 40, which has a guide slope, rotates relative to the main body 10 around a preset axis, different positions on the guide slope with different inclination angles shift positions as the guide slope rotates around the preset axis. This changes the orientation of each part on the guide slope relative to the preset axis, allowing the first air-passing component 30 and / or the second air-passing component 40 to rotate the portion of the guide slope with a specific inclination angle to a suitable position. This allows the airflow passing through this portion to blow onto the user at a specific blowing angle. With this configuration, a user in a certain location within the bathroom can be successively blown by airflow passing through two positions on the guide slope with different inclination angles, thus allowing the user to perceive a change in airflow direction without the need for a flap.

[0039] It is understandable that changing the blowing angle of the airflow to make the user feel the change in wind direction is unrelated to the installation position of the air control device. Whether the air control device is installed on the ceiling, ceiling or vertical wall, it will not affect the rotation of the first air passage 30 and / or the second air passage 40 around the preset position.

[0040] Specifically, at least one of the first air-passing component 30 and the second air-passing component 40, which has a guide slope, forms an adjustable floating gap with the surface where the air control device is located. The height of the floating gap is related to the width of the end air gap 20; changing the height of the floating gap changes the width of the end air gap 20. Increasing the floating gap to move the first air-passing component 30 and / or the second air-passing component 40 away from the surface increases the width of the end air gap 20, thereby increasing the airflow volume. Decreasing the floating gap to move the first air-passing component 30 and / or the second air-passing component 40 closer to the surface decreases the width of the end air gap 20, thereby decreasing the airflow volume.

[0041] Optionally, at least one of the first airflow member 30 and the second airflow member 40, which has a guide slope, is movable along a straight line direction perpendicular to the provided surface, and the height direction of the floating interval is perpendicular to the provided surface. See reference. Figures 3-4 , Figures 6-7 , Figures 10-11 In the diagram, arrow V represents the height direction of the floating interval and is perpendicular to the direction indicated by arrow H, and also perpendicular to the set surface. Figures 1 to 7 In the air control device shown, the first airflow component 30 has a guide slope, which is the first sidewall 31 of the first airflow component 30. The first airflow component 30 is movable relative to the fuselage 10 in the direction indicated by arrow V, and is rotatable relative to the fuselage 10 about a preset pivot. Figures 8-11 In the air control device shown, the first air passage 30 and the second air passage 40 both have a guide slope. The guide slope includes the first side wall 31 of the first air passage 30 and the second side wall 41 of the second air passage 40. The first air passage 30 is movable relative to the body 10 in the direction indicated by arrow V, and the second air passage 40 is rotatable relative to the body 10 around a preset rotating axis.

[0042] Furthermore, the preset rotating shaft for rotating the first air passage 30 and / or the second air passage 40 to change the air direction is parallel to... Figures 3-4 , Figures 6-7 , Figures 10-11The direction indicated by arrow V is that the preset rotating axis is perpendicular to the surface of the air control device and the air collecting plate 11. Specifically, the air control device also includes a floating unit 50 and an airflow control component 60 disposed on the body 10. The airflow control component 60 can output linear displacement. The floating unit 50 is connected to the output end of the airflow control component 60 and carries the first airflow passer 30. The first airflow passer 30 has a guide slope and can be driven by the airflow control component 60. Thus, the floating interval between the first airflow passer 30 and the surface can change as the airflow control component 60 drives the first airflow passer 30 to translate relative to the second airflow passer 40. The direction of the linear displacement velocity is the direction indicated by arrow V in the figure.

[0043] The floating unit 50 and the first airflow element 30 move synchronously under the drive of the airflow control element 60. (See reference...) Figure 2 and Figure 9 The floating unit 50 includes a limiting part 51 extending to the bottom end of the first air passage 30. The bottom end of the first air passage 30 is the end of the first air passage 30 facing away from the air conditioning device. When the air conditioning device is installed on the ceiling or indoor ceiling, the bottom end of the first air passage 30 is the end of the first air passage 30 facing the ground. The limiting part 51 and the bottom end of the first air passage 30 form a sliding contact. The floating unit 50 and the first air passage 30 move up and down and translate in the vertical direction in response to the power output of the air volume regulating component. The limiting part 51 contacts the bottom end of the first air passage 30 to support the first air passage 30 and prevent the first air passage 30 from falling. When the first air passage 30 rotates relative to the body 10 around a preset pivot to change the air direction, the limiting part 51 slides relative to the bottom end of the first air passage 30.

[0044] Optionally, Figures 1 to 7 The air conditioning device shown is installed on a suspended ceiling or indoor ceiling. The surface is a horizontal plane. The preset rotating shaft is perpendicular to the surface and extends in the vertical direction. The second air passage 40 is fixedly installed on the body 10, specifically it can be fixedly installed on the air collection plate 11. The first air passage 30 can rotate relative to the body 10 around the preset rotating shaft to change the air direction of the air conditioning device. It can also move up and down relative to the body 10 along the extension direction of the preset rotating shaft under the drive of the air volume control component 60 and the floating unit 50, so as to change the width of the terminal air gap 20 and thus change the air volume of the air conditioning device.

[0045] Furthermore, Figures 1 to 7In the air control device shown, the first air duct 30 and the second air duct 40 are both coaxially arranged annular structures. A preset rotating shaft serves as the common axis of the first air duct 30 and the second air duct 40. The second air duct 40 surrounds the outer periphery of the first air duct 30. The end air gap 20 is an annular gap formed between the outer periphery of the first air duct 30 and the inner periphery of the second air duct 40. The outer periphery of the first air duct 30 and the inner periphery of the second air duct 40 respectively form the first sidewall 31 and the second sidewall 41 of the end air gap 20. The guide slope includes the first sidewall 31 and / or the second sidewall 41. (See reference...) Figure 4 The first sidewall 31, which serves as a flow guiding slope, includes a first flow guiding slope 311 and a second flow guiding slope 312. The inclination angle of the end of the first flow guiding slope 311 away from the set surface is β1, and the inclination angle of the end of the second flow guiding slope 312 away from the set surface is β2, where β1 > β2.

[0046] Further, see Figures 2-3 , Figures 6-7 The air control device also includes an airflow direction control component 70 located on the fuselage 10. The airflow direction control component 70 includes an airflow direction adjustment motor 72 and a transmission gear 71. The inner circumference of the first airflow component 30 is provided with internal teeth 32 that mesh with the transmission gear 71. The internal teeth 32 and the teeth of the transmission gear 71 form a sliding fit along the height direction of the floating interval, which is the extension direction of the preset rotating shaft. The significance of the sliding fit between the internal teeth 32 and the transmission gear 71 is that when the first airflow component 30 is driven by the airflow control component 60 to move up, down, or horizontally along the preset rotating shaft, the internal teeth 32 and the transmission gear 71 can always mesh, avoiding the situation where the airflow direction control component 70 cannot output power to the first airflow component 30.

[0047] In other embodiments, the transmission gear 71 can be replaced by a friction wheel, which forms a static friction transmission connection with the inner circumference of the first air passage 30. Alternatively, the transmission gear 71 and the friction wheel can be omitted, and the first air passage 30 can be directly connected to and driven by the wind direction adjustment motor 72.

[0048] Optionally, see Figures 2-3The air conditioning device also includes a diversion cover 80 connected to the body 10. The diversion cover 80 covers the top of the first air passage 30. The top of the first air passage 30 is the end of the first air passage 30 facing the air conditioning device. When the air conditioning device is installed on a ceiling panel or indoor ceiling, the top of the first air passage 30 is the end of the first air passage 30 facing away from the ground. Specifically, the diversion cover 80 can be located at the air outlet 112. The airflow flowing along the air duct 122 to the air outlet 112 is blocked by the diversion cover 80 and then diverted and diffused to the outer peripheral edge of the diversion cover 80, and then flows into the terminal air gap 20. Therefore, the diversion cover 80 can evenly disperse small streams of airflow into the terminal air gap 20, and the airflow blown into the room finally forms a ring-shaped flow field. The wind direction control component 70 can be installed on the end of the diversion cover 80 facing away from the set surface. When the floating interval increases, the first air passage component 30 moves away from the diversion cover 80, and when the floating interval decreases, the first air passage component 30 moves closer to the diversion cover 80.

[0049] To reduce the kinetic energy loss when the airflow encounters the airflow cover, the side of the diverter cover 80 facing away from the first airflow component 30 is a conical surface. The distance between the side of the diverter cover 80 facing away from the first airflow component 30 and the surface is reduced in the direction close to the preset rotation axis. The conical surface can guide the airflow away from the preset rotation axis and diffuse towards the outer peripheral edge of the diverter cover 80, which is conducive to forming multiple airflows entering the end air gap 20.

[0050] Optionally, see Figures 2-4 , Figures 9-11 The heating element 21 is annular and surrounds the outer periphery of the first air vent 30, and the heating element 21 is located in the end air gap 20.

[0051] Optionally, see Figure 5 The air volume control component 60 includes an air volume regulating motor 62 and a lead screw 61. The air volume regulating motor 62 can be directly installed on the body 10 or on the side of the diverter cover 80 facing away from the surface. The axial direction of the lead screw 61 is perpendicular to the surface of the air control device. The lead screw 61 can make a spiral movement along the axial direction of the lead screw 61 under the drive of the air volume regulating motor 62. The spiral movement includes the translational movement of the lead screw 61 along the axial direction of the lead screw 61. The floating unit 50 is rotatably installed at the end of the lead screw 61 and can make a linear translation along the axial direction of the lead screw 61 when the lead screw 61 makes a spiral movement. Due to the supporting and receiving effect of the limiting part 51 on the bottom end of the first air passage component 30, the first air passage component 30 moves away from the surface synchronously with the floating unit 50, or moves closer to the surface synchronously with the floating unit 50.

[0052] As a preferred option Figure 5The airflow control component 60 shown is a motor ball screw mechanism. In other embodiments, the airflow control component 60 can also be a lifting mechanism composed of a motor, gears, and racks, or a cylinder mechanism, an electric push rod mechanism, or a scissor lifting mechanism, etc. When the airflow control component 60 is installed on the side of the diffuser cover 80 facing away from the surface it is installed on, airflow can be prevented from affecting the airflow control component 60, reducing the space occupied by the airflow control component 60 inside the housing 12 or on the surface of the air collection plate 11.

[0053] Furthermore, the wind direction control component 70 can be directly installed on the fuselage 10, or on the side of the diffuser cover 80 facing away from the intended surface, or on the floating unit 50. Taking the wind direction control component 70, which includes a wind direction adjustment motor 72 and a transmission gear 71, as an example:

[0054] When the air direction control component 70 is installed on the side of the body 10 or the diverter cover 80 facing away from the set surface, the air direction adjustment motor 72 is installed on the side of the body 10 or the diverter cover 80 facing away from the set surface, and the transmission gear 71 is connected to the output end of the air direction adjustment motor 72. At this time, the transmission gear 71 and the internal gear 32 of the first air passage component 30 form a sliding engagement that slides along the preset rotating shaft. Even if the first air passage component 30 moves up and down or horizontally along the preset rotating shaft, the internal gear 32 and the transmission gear 71 remain in a meshing state. Therefore, the air direction and air volume of the air dispatching device can be adjusted at the same time.

[0055] When the wind direction control component 70 is installed on the floating unit 50, the wind direction adjustment motor 72 is installed on the floating unit 50, and the transmission gear 71 is connected to the output end of the wind direction adjustment motor 72. At this time, there is no need to form a sliding fit between the transmission gear 71 and the internal gear 32 of the first air passage component 30. The first air passage component 30, the transmission gear 71 and the wind direction adjustment motor 72 can rise and fall synchronously with the floating unit 50. That is, the air volume control component 60 is used to generate the power to drive the first air passage component 30, the floating unit 50 and the wind direction control component 70 to move synchronously in a straight line. With this setting, the wind direction and air volume can be adjusted simultaneously for the air dispatching device.

[0056] like Figure 1 , Figure 3 , Figures 6-7As shown, when the airflow control component 70 is installed on the side of the splitter cover 80 facing away from the designated surface, and the airflow adjustment motor 72 and the transmission gear 71 are both surrounded by the first airflow component 30, the airflow adjustment motor 72 does not need to be installed on the air collection plate 11. This saves the layout space of the air collection plate 11, allowing it to accommodate other functional devices, while also preventing airflow from affecting the airflow control component 70. In summary, the airflow control component 70 can be directly installed on the side of the splitter cover 80 facing away from the designated surface, or it can be directly installed on the floating unit 50, with the floating unit 50 driven to connect to the airflow control component 60, and the airflow control component 60 installed on the side of the splitter cover 80 facing away from the designated surface.

[0057] See Figures 9-11 In some embodiments, the air control device further includes a light-transmitting cover 90 and a light-emitting element 14. The light-transmitting cover 90 is disposed on the bottom end of the first air-passing element 30 and is fixedly connected to the first air-passing element 30, such as... Figures 10-11 The diversion cover 80, the first air passage component 30, and the light-transmitting cover 90 are arranged sequentially in the direction indicated by arrow V in the figure. That is, the distance from the diversion cover 80, the first air passage component 30, and the light-transmitting cover 90 to the surface increases sequentially. The side of the diversion cover 80 facing away from the surface is the side of the diversion cover 80 that is relatively close to the first air passage component 30 and the light-transmitting cover 90. The light-emitting component 14 is set on the side of the diversion cover 80 facing away from the surface. The light-transmitting cover 90 allows the light from the light-emitting component 14 to pass through and enter the indoor space, thereby enabling the air control device to have a lighting function.

[0058] Optionally, the diversion cover 80, the first air passage component 30, the second air passage component 40, the light-transmitting cover 90, and the air outlet 112 are coaxially arranged, and the preset pivot is the common axis of the diversion cover 80, the first air passage component 30, the second air passage component 40, the light-transmitting cover 90, and the air outlet 112.

[0059] The width of the end air gap 20 is the width at the outlet of the end air gap 20. The outlet of the end air gap 20 is annular. The outlet of the end air gap 20 is formed between the outer peripheral edge of the bottom end of the first air passage 30 and the inner peripheral edge of the bottom end of the second air passage 40. The bottom end of the second air passage 40 is the end of the second air passage 40 that faces away from the surface it is set on. Figure 1 As shown, in some embodiments, the second air passage 40 is installed on the side of the air collecting plate 11 facing away from the surface and surrounds the air outlet 112, and the bottom end of the second air passage 40 is the end of the second air passage 40 facing away from the air collecting plate 11.

[0060] See Figure 6The guide slope includes a first guide slope 311 and a second guide slope 312, which belong to the first sidewall 31. The width of the end air gap 20 is L1 at the first guide slope 311 and L2 at the second guide slope 312. L1 is the distance from the first guide slope 311 to the inner peripheral edge of the bottom end of the second air passage 40, and L2 is the distance from the second guide slope 312 to the inner peripheral edge of the bottom end of the second air passage 40. When the air volume control component 60 drives the floating unit 50 and the first air passage component 30 to translate a certain distance away from the set surface, the width of the end air gap 20 increases. At this time, the width of the end air gap 20 is L3 at the first guide slope 311 and L4 at the second guide slope 312. L3 is the distance from the first guide slope 311 to the inner peripheral edge of the bottom end of the second air passage component 40, and L4 is the distance from the second guide slope 312 to the inner peripheral edge of the bottom end of the second air passage component 40. L3 > L1, L4 > L2.

[0061] See Figures 8-9 , Figures 10-11 In the second embodiment of this utility model, the second air passage 40, surrounding the first air passage 30, is rotatably mounted on the body 10 around a preset rotating shaft, specifically rotatably mounted on the air collecting plate 11. The guide slope includes the second sidewall 41 of the second air passage 40, and the second sidewall 41 includes a third guide slope 411 and a fourth guide slope 412. The inclination angle of the third guide slope 411 relative to the set surface and the inclination angle of the fourth guide slope 412 relative to the set surface are different. The air direction control component 70 includes an air direction adjusting motor 72 mounted on the air collecting plate 11 and a transmission gear 71 connected to the air direction adjusting motor 72. The outer periphery of the second air passage 40 is provided with external teeth 42 meshing with the transmission gear 71. The air direction adjusting motor 72 drives the second air passage 40 to rotate relative to the body 10 through the transmission gear 71, thereby adjusting the air direction. The air volume control component 60 drives the first air passage 30 to translate relative to the body 10 along the extension direction of the preset rotating shaft, thereby adjusting the air volume.

[0062] See Figure 1 and Figure 8 The air outside the body 10 is first drawn into the housing 12 through the air inlet 111 by the fan. Then the airflow is driven by the impeller 13 and flows along the air duct 122 to the air outlet. Next, the airflow flows into the end air gap between the first air passage 30 and the second air passage 40. Finally, the airflow is blown out from the end air gap 20 and blown into the indoor space. Figure 1 and Figure 8 The arrows in the diagram indicate the direction of airflow.

For the sake of brevity, not all possible combinations of the technical features in the above 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.
