Description

Technical Field

[0001] This disclosure relates to the field of air treatment technology, and more specifically, to an air outlet device, an indoor unit, and an air conditioner. Background Technology

[0002] In related technologies, some air handling equipment, such as air conditioners, are equipped with air outlets, which have air vents. Currently, some air outlets are equipped with door panels that can open or close the air vents; however, when the air vents are open, the door panels are inconvenient to close, affecting the user experience. Utility Model Content

[0003] The purpose of this disclosure is to provide an air outlet device that facilitates the folding of the door panel when the air outlet is open.

[0004] To achieve the above objectives, this disclosure provides an air outlet device, comprising: An air outlet structure has an air outlet channel, the air outlet structure comprising a first air duct section and a second air duct section arranged at an angle, the first air duct section being provided with an air outlet, and the second air duct section being connected to the upper side of the first air duct section; and The opening and closing mechanism includes a door panel that is slidably disposed on the first air duct section to open or close the air outlet. When the air outlet is opened, at least a portion of the door panel is housed in an arrangement space located above the first air duct section.

[0005] Through the above technical solution, in the air outlet device provided in this disclosure, since the first air duct section and the second air duct section are arranged at an angle, and the second air duct section is connected to the upper side of the first air duct section, the first air duct section and the second air duct section can form an arrangement space located above the first air duct section and to the side of the second air duct section. This arrangement space is located outside the air outlet channel. Therefore, when the door panel opens the air outlet, at least part of the door panel can be stored using the arrangement space. Thus, the air outlet device of this disclosure facilitates the storage of the door panel when the air outlet is opened.

[0006] In addition, the air vents can be opened or closed by sliding the door panel, making the structure simple and easy to operate. Compared to rotating the air vents, the sliding air vent design takes up less space and is easier to assemble and maintain.

[0007] In some possible implementations, the first air duct section and the second air duct section are perpendicular to each other. The first air duct section is arranged in a front-to-back direction, and the second air duct section is arranged in a vertical direction. The air outlet is provided on the front side of the first air duct section. Thus, the air outlet channel can be constructed as an L-shaped air duct, the air outlet structure can be constructed as an L-shaped structure, and it is convenient for the air outlet to face forward, thereby realizing the front air outlet of the air outlet device.

[0008] In some possible implementations, the opening and closing mechanism includes a drive member and a transmission structure, the transmission structure being drively connected between the drive member and the door panel. The drive member is used to drive the door panel to slide via the transmission structure. Therefore, compared to a direct drive of the door panel by the drive member, this disclosure adds a transmission structure between the drive member and the door panel. On the one hand, the transmission structure can increase the transmission ratio, thereby allowing the door panel to slide smoothly. On the other hand, since there is insufficient space near the air outlet, the transmission structure can also increase the transmission distance between the drive member and the door panel, thus facilitating the installation of the drive member.

[0009] In some possible implementations, both the drive component and the transmission structure are arranged within the arrangement space. Therefore, the drive component and transmission structure can be arranged within the arrangement space, eliminating the need for additional space on the air outlet structure. This facilitates a more rational arrangement of the air outlet components, thereby reducing the size of the air outlet and achieving miniaturization.

[0010] In some possible implementations, the opening and closing mechanism includes a hinge structure hinged between the transmission structure and the door panel. This hinge structure is configured such that, when the lower end of the door panel slides downward to its limit position, the upper end of the door panel swings around the lower end towards the air outlet, causing the door panel to press against the first air duct section and close the air outlet. Thus, the hinge structure also allows the door panel to rotate, allowing the upper end of the door panel to swing towards the air outlet before closing the air outlet, thereby reliably pressing the upper end of the door panel against the air outlet and improving the sealing performance at the air outlet.

[0011] In some possible implementations, the first air duct section is provided with a first slide rail and a second slide rail. The upper end of the door panel is slidably connected to the first slide rail, and the lower end of the door panel is slidably connected to the second slide rail. Both the bottom of the first slide rail and the bottom of the second slide rail are provided with arc-shaped grooves, which are used to allow the upper or lower end of the door panel to rotate. Thus, the upper and lower ends of the door panel are respectively located in the first and second slide rails, allowing the upper end of the door panel to rotate around the lower end. The arc-shaped grooves facilitate the swinging of the upper end of the door panel around the lower end.

[0012] In some possible implementations, both the first and second slide rails extend downwards at an angle towards the air outlet, wherein the angle between the first slide rail and the vertical plane is smaller than the angle between the second slide rail and the vertical plane. Thus, as the door panel slides downwards, the upper end of the door panel gradually approaches the second slide rail, thereby facilitating the upper end of the door panel to swing around the lower end towards the air outlet when the lower end of the door panel slides to its limit.

[0013] In some possible implementations, the hinge structure includes at least one link section that extends downwards and towards the side closest to the air outlet when the door panel is closed. Thus, at least one link section can serve to press the upper end of the door panel against the air outlet.

[0014] In some possible implementations, the transmission structure includes a gear and a rack connected in a transmission manner. The gear is connected to the drive component, and the rack extends vertically and is connected to the door panel. Thus, the drive component can drive the gear to rotate, thereby causing the rack to move up and down, which in turn causes the door panel to slide up and down, opening or closing the air vent.

[0015] In some possible implementations, the opening and closing mechanism includes a connecting frame comprising a first plate and a second plate perpendicular to each other. The first plate extends vertically and is connected to the rack, while the second plate is connected to the door panel, with the second plate extending in the same direction as the door panel. Thus, the first plate and the rack are reliably connected. Compared to a direct connection between the first plate and the door panel, the connection area between the connecting frame and the door panel is increased because the second plate extends in the same direction as the door panel, thereby improving the reliability of the connection between the connecting frame and the door panel.

[0016] In some possible implementations, the air outlet device includes a main air duct structure, the air outlet structure includes a mounting plate, the air outlet structure is mounted to the main air duct structure via the mounting plate, and the air outlet channel is connected to the main air duct of the main air duct structure. Thus, the mounting plate allows for the assembly of the main air duct structure and the air outlet structure, allowing airflow from the main air duct to flow into the air outlet channel, thereby facilitating air outlet.

[0017] In some possible implementations, the main air duct structure includes a volute, and the air outlet structure is mounted to the volute via a mounting plate. This allows the air outlet duct to be positioned close to the volute, thereby shortening the airflow path.

[0018] In some possible implementations, the air outlet device includes an electrical control box, which is arranged above the first air duct section and in front of the second air duct section. This allows the space above the first air duct section and in front of the second air duct section to be used to arrange the electrical control box, thereby facilitating a rational arrangement of components and achieving a compact design for the air outlet device.

[0019] According to a second aspect of this disclosure, an indoor unit is provided, including the air outlet device as described above.

[0020] According to a third aspect of this disclosure, an air conditioner is provided, including the air outlet device as described above.

[0021] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "left," "right," "front," and "back" are used for reference. Figure 1 , Figure 2 and Figure 4 The terms "up," "down," "front," "back," "left," and "right" are used in the following description, where the up / down, left / right, and front / back directions are mutually perpendicular. The up / down direction can refer to the direction of gravity of the air outlet device or a direction perpendicular to the direction of gravity of the air outlet device; this disclosure does not limit this. "Inner" and "outer" refer to the inside and outside of the contours of each component itself. "Upstream" and "downstream" are defined based on the direction of airflow. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which this disclosure will not repeat.

[0026] According to some embodiments of this disclosure, an air outlet device is provided, with reference to... Figures 1 to 6 As shown, the air outlet device includes: an air outlet structure 1 having an air outlet channel 10, the air outlet structure 1 including a first air duct section 11 and a second air duct section 12 arranged at an angle, the first air duct section 11 being provided with an air outlet 13, and the second air duct section 12 being connected to the upper side of the first air duct section 11; and an opening and closing mechanism 2 including a door panel 21, the door panel 21 being slidably disposed on the first air duct section 11 to open or close the air outlet 13, and when the door panel 21 opens the air outlet 13, at least a portion of the door panel 21 is housed in the arrangement space 100 located above the first air duct section 11.

[0027] Through the above technical solution, in the air outlet device provided in this disclosure, since the first air duct section 11 and the second air duct section 12 are arranged at an angle, and the second air duct section 12 is connected to the upper side of the first air duct section 11, the first air duct section 11 and the second air duct section 12 can form an arrangement space 100 located above the first air duct section 11 and to the side of the second air duct section 12. This arrangement space 100 is located outside the air outlet channel 10. Therefore, when the door panel 21 opens the air outlet 13, at least part of the door panel 21 can be stored using the arrangement space 100. Thus, the air outlet device of this disclosure facilitates the storage of the door panel 21 when the air outlet 13 is opened.

[0028] In addition, the air outlet 13 can be opened or closed by sliding the door panel 21, which is simple in structure and easy to operate. Compared with the method of opening and closing the air outlet 13 by rotation, the method of opening and closing the air outlet 13 by sliding takes up less space and is convenient for assembly and maintenance.

[0029] It should be noted that the airflow within the air outlet duct 10 can flow sequentially through the second air duct section 12 and the first air duct section 11, and then exit from the air outlet 13. In other words, the second air duct section 12 is located upstream of the first air duct section 11. Furthermore, when the door panel 21 is fully opened to the air outlet 13, all door panels 21 can be arranged within the arrangement space 100, and this disclosure does not impose any restrictions on this arrangement.

[0030] In some embodiments of this disclosure, reference is made to Figure 2 and Figure 4 As shown, the first air duct section 11 and the second air duct section 12 can be perpendicular to each other, that is, the angle between the first air duct section 11 and the second air duct section 12 is a right angle. The air outlet duct 10 can be constructed as an L-shaped air duct, and the air outlet structure 1 can be constructed as an L-shaped structure. The first air duct section 11 is arranged in the front-to-back direction, and the second air duct section 12 is arranged in the up-down direction. This facilitates the arrangement of the first air duct section 11 and the second air duct section 12. An air outlet 13 can be provided on the front side of the first air duct section 11. This facilitates the air outlet 13 to discharge air forward, thereby realizing the front air discharge of the air outlet device. Of course, in other embodiments, the angle between the first air duct section 11 and the second air duct section 12 can also be an obtuse angle or an acute angle, and this disclosure does not limit this.

[0031] It should be noted that the first air duct section 11 and the second air duct section 12 are perpendicular to each other. This can be understood as the extension direction of the first air duct section 11 being perpendicular to the extension direction of the second air duct section 12. In addition, since the air outlet 13 is located in front of the first air duct section 11, when the door panel 21 opens the air outlet 13, the door panel 21 can be located on the front side of the arrangement space 100, so as to facilitate the door panel 21 to open and close the air outlet 13 by sliding.

[0032] In some embodiments of this disclosure, reference is made to Figures 1 to 5 As shown, the opening and closing mechanism 2 may include a driving member 22 and a transmission structure 23. The transmission structure 23 is drivingly connected between the driving member 22 and the door panel 21. The driving member 22 is used to drive the door panel 21 to slide through the transmission structure 23. In this way, compared with the door panel 21 being directly driven by the driving member 22, this disclosure adds a transmission structure 23 between the driving member 22 and the door panel 21. On the one hand, the transmission structure 23 can increase the transmission ratio, thereby making the door panel 21 slide smoothly. On the other hand, since the space near the air outlet 13 is insufficient, the transmission structure 23 can also increase the transmission distance between the driving member 22 and the door panel 21, thereby facilitating the installation of the driving member 22.

[0033] In some implementations, reference Figures 1 to 6 As shown, both the drive component 22 and the transmission structure 23 can be arranged in the arrangement space 100. Thus, the drive component 22 and the transmission structure 23 can be arranged within the arrangement space 100, eliminating the need for additional space on the air outlet structure 1 to accommodate them. This facilitates a more rational arrangement of the air outlet device components, thereby reducing the size of the air outlet device and achieving miniaturization. The drive component 22 can be constructed as a motor; this disclosure does not limit its application.

[0034] In some implementations, reference Figures 1 to 5 As shown, the transmission structure 23 includes a gear 231 and a rack 232 connected by transmission. The gear 231 is connected to the driving member 22, and the rack 232 extends in the vertical direction and is connected to the door panel 21 by transmission. In this way, the driving member 22 can drive the gear 231 to rotate, thereby driving the rack 232 to move up and down, thereby driving the door panel 21 to slide up and down, realizing the opening or closing of the air outlet 13. Of course, in other embodiments, the transmission structure 23 may also include a lead screw and a lead nut connected by transmission, wherein the lead screw is connected to the driving member 22 by transmission, and the lead nut is fixed to the door panel 21, thereby also realizing the up and down sliding of the door panel 21.

[0035] In some embodiments, reference Figures 1 to 5 As shown, the opening and closing mechanism 2 may include a connecting frame 25, which includes a first plate 251 and a second plate 252 that are perpendicular to each other. The first plate 251 extends vertically and is connected to a rack 232, while the second plate 252 is connected to a door panel 21, and the extension direction of the second plate 252 is the same as that of the door panel 21. In this way, the first plate 251 and the rack 232 are reliably connected. Compared to a direct connection between the first plate 251 and the door panel 21, the connection area between the connecting frame 25 and the door panel 21 is increased because the extension direction of the second plate 252 is the same as that of the door panel 21. Therefore, the reliability of the connection between the connecting frame 25 and the door panel 21 can be improved.

[0036] In some implementations, reference Figures 1 to 5As shown, the opening and closing mechanism 2 may include a hinge structure 24 hinged between the transmission structure 23 and the door panel 21. The hinge structure 24 may be configured such that when the lower end 211 of the door panel 21 slides downward to its limit position, the upper end 212 of the door panel 21 swings around the lower end 211 of the door panel 21 toward the side closer to the air outlet 13, so that the door panel 21 presses against the first air duct section 11 and closes the air outlet 13. In this way, the hinge structure 24 can also allow the door panel 21 to rotate. Thus, before the door panel 21 closes the air outlet 13, the hinge structure 24 can allow the upper end 212 of the door panel 21 to swing toward the side closer to the air outlet 13, thereby reliably pressing the upper end 212 of the door panel 21 against the air outlet 13, thereby improving the sealing performance at the air outlet 13.

[0037] In some embodiments, the door panel 21 may be provided with a sealing ring. The swinging of the door panel 21 can cause the upper end 212 of the door panel 21 to press against the sealing ring. Thus, such a arrangement also helps to reliably seal the air outlet 13 with the door panel 21.

[0038] In some embodiments, reference Figures 1 to 6 As shown, the first air duct section 11 can be provided with a first slide rail 14 and a second slide rail 15. The upper end 212 of the door panel 21 can be slidably connected to the first slide rail 14, and the lower end 211 of the door panel 21 can be slidably connected to the second slide rail 15. Both the bottom of the first slide rail 14 and the bottom of the second slide rail 15 are provided with arc-shaped grooves 16, which are used to allow the upper end 212 or the lower end 211 of the door panel 21 to rotate. In this way, the upper end 212 and the lower end 211 of the door panel 21 are respectively located in the first slide rail 14 and the second slide rail 15, meaning the upper end 212 and the lower end 211 of the door panel 21 are in different slide rails, thus allowing the upper end 212 of the door panel 21 to rotate around the lower end 211. The arc-shaped grooves 16 facilitate the swinging of the upper end 212 of the door panel 21 around the lower end 211.

[0039] In some embodiments, reference Figure 2 , Figure 4 and Figure 6 As shown, both the first slide rail 14 and the second slide rail 15 can extend downwards at an angle towards the air outlet 13. This allows the door panel 21 to gradually approach the air outlet 13 as it slides downwards. The angle between the first slide rail 14 and the vertical plane can be smaller than the angle between the second slide rail 15 and the vertical plane. Thus, as the door panel 21 slides downwards, its upper end 212 gradually approaches the second slide rail 15. This allows the upper end 212 of the door panel 21 to swing around its lower end 211 towards the air outlet 13 when the lower end 211 of the door panel 21 slides to its limit. In some embodiments, reference... Figure 2 , Figure 4 and Figure 6 As shown, the bottom of the first slide 14 can be positioned closer to the air outlet 13 than the second slide 15, and the bottom of the first slide 14 can be higher than the bottom of the second slide 15 and lower than the top of the second slide 15. This disclosure does not impose any limitations on this.

[0040] In some embodiments, reference Figures 1 to 6 As shown, a first slide rail 14 and a second slide rail 15 can be provided on both the left and right sides of the first air duct section 11, and this disclosure does not impose any restrictions on this.

[0041] In some implementations, reference Figures 1 to 5 As shown, the hinge structure 24 may include at least one connecting rod 241. When the door panel 21 closes the air outlet 13, at least one connecting rod 241 extends downwards and tilts towards the side closer to the air outlet 13. In this way, at least one connecting rod 241 can serve to press the upper end 212 of the door panel 21 against the air outlet 13. Of course, the hinge structure 24 may also include multiple connecting rods 241 to improve the smoothness of the upper end 212 of the door panel 21 when swinging, and this disclosure does not limit this.

[0042] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 3 and Figure 5 As shown, the air outlet device includes a main air duct structure (not shown in the figure). The air outlet structure may include a mounting plate 3. The air outlet structure 1 is mounted on the main air duct structure via the mounting plate 3. The air outlet channel 10 is connected to the main air duct of the main air duct structure. In this way, the main air duct structure and the air outlet structure 1 can be assembled using the mounting plate 3. The airflow from the main air duct can flow into the air outlet channel 10, thereby facilitating air outlet.

[0043] In some embodiments, the mounting plate 3 can be connected to the main air duct structure by fasteners, and this disclosure does not limit this.

[0044] In some embodiments, the main air duct may be connected to the second air duct section 12, that is, the second air duct section 12 is connected between the first air duct section 11 and the main air duct, and this disclosure does not limit this.

[0045] In some embodiments, the main air duct structure may include a volute (not shown in the figure), and the air outlet structure 1 can be mounted on the volute via a mounting plate 3. In this way, the air outlet duct 10 can be located close to the volute, thereby shortening the airflow path.

[0046] In some embodiments of this disclosure, reference is made to Figure 2 and Figure 4As shown, the air outlet device may include an electrical control box 4, which is arranged on the upper side of the first air duct section 11 and in front of the second air duct section 12. In this way, the space above the first air duct section 11 and the space in front of the second air duct section 12 can be used to arrange the electrical control box 4, thereby facilitating the rational arrangement of components and achieving a compact design of the air outlet device.

[0047] The opening and closing process of the opening and closing mechanism 2 will now be described in detail with reference to the specific embodiments described above. Figure 2 and Figure 4 As shown, when the air outlet 13 needs to be opened, the drive unit 22 drives the gear 231 to rotate, which in turn drives the rack 232 to move upward. Thus, the door panel 21 can be slid upward through the connecting frame 25. At this time, the upper end 212 of the door panel 21 first swings around the lower end 211 of the door panel 21 to the side away from the air outlet 13. Then, the upper end 212 and the lower end 211 of the door panel 21 slide upward along the first slide rail 14 and the second slide rail 15 respectively. During this process, the door panel 21 is gradually housed in the arrangement space 100 above the first air duct section 11.

[0048] When it is necessary to close the air outlet 13, the upper end 212 and the lower end 211 of the door panel 21 slide downwards along the first slide rail 14 and the second slide rail 15 respectively. When the lower end 211 of the door panel 21 moves to the limit position, the upper end 212 of the door panel 21 swings around the lower end 211 of the door panel 21 towards the side closer to the air outlet 13, thereby achieving reliable closure of the air outlet 13.

[0049] According to a second aspect of this disclosure, an indoor unit is provided, including the air outlet device as described above. This indoor unit possesses all the beneficial effects of the aforementioned air outlet device, which will not be elaborated upon here. In some embodiments, the indoor unit of this disclosure can be constructed as a vertical indoor unit, i.e., the aforementioned vertical direction can be the direction of gravity of the vertical indoor unit.

[0050] According to a third aspect of this disclosure, an air conditioner is provided, including the air outlet device as described above. This air conditioner has all the beneficial effects of the described air outlet device, which will not be elaborated upon herein.

[0051] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0052] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0053] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
