Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a bottom air outlet mechanism and a cabinet-type air conditioner indoor unit. Background Technology

[0002] In related technologies, the decorative panel of the bottom air outlet mechanism in a cabinet air conditioner with a bottom air outlet function can rotate in the bottom air outlet state. This decorative panel simultaneously functions as an outlet and a guide, and its rotation also causes the grille fixed to it to swing, achieving a left-right airflow function. However, this structural design results in ineffective airflow when the grille on the decorative panel rotates to a position on the chassis that is not an air outlet, reducing the air volume output of the air conditioner in the bottom air outlet state. Utility Model Content

[0003] To overcome the problem in related technologies where cabinet air conditioner indoor units with down-discharge function experience partially ineffective airflow and reduced air volume during the left-right sweeping process caused by the rotation of the decorative panel of the down-discharge mechanism, this utility model proposes a down-discharge mechanism and a cabinet air conditioner indoor unit: A first aspect of this application provides a downward air outlet mechanism applied to an air conditioning device, the downward air outlet mechanism comprising: The chassis includes a disc-shaped main body; A support frame assembly is disposed on the disc-shaped body.

Detailed Implementation

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0028] The following describes this embodiment in detail with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and examples can be combined with each other.

[0029] In related technologies, the decorative panel 211 of the lower air outlet mechanism of a cabinet air conditioner with a lower air outlet function can rotate in the lower air outlet state, and the decorative panel 211 of the lower air outlet mechanism has both air outlet and air guiding functions. While the decorative panel 211 rotates, it also drives the grille fixed to it to swing, achieving a left-right air sweeping function. However, this structural design has the following problems: the width of the chassis air vent 13 of the lower air outlet mechanism is limited and fixed. When the width of the open area 213 of the decorative panel (i.e., the decorative panel air vent) is larger than the width of the chassis air vent 13, the left-right swing of the decorative panel 211 will inevitably rotate to the non-air outlet blind area of ​​the chassis, as shown in the example below. Figure 1 The location shown in the figure results in a portion of the open area 213 being unable to supply air.

[0030] To address the above technical problems, this embodiment proposes a downward air outlet mechanism applied to an air conditioning device. The downward air outlet mechanism includes: The chassis includes a disc-shaped main body; A support frame assembly is disposed on a disc-shaped main body. The support frame assembly includes a support frame main body and an air guide plate. The support frame main body is provided with a first air outlet. The air guide plate is rotatably disposed on the support frame main body and located inside the first air outlet. A decorative panel assembly is disposed on a disc-shaped body and is rotatable along the circumferential direction of the disc-shaped body. The decorative panel assembly includes a decorative panel extending along the circumferential and height directions of the disc-shaped body. The decorative panel includes a closed area and an open area. The decorative panel has a first rotational position that aligns the closed area with a first air vent and closes the first air vent, and a second rotational position that aligns the open area with the first air vent and opens the first air vent. The decorative panel is configured to switch between the first rotational position and the second rotational position.

[0031] In this embodiment, a support frame assembly is installed on the disc-shaped main body of the chassis, and this support frame assembly does not rotate with the decorative panel assembly. By placing the air guide plate inside the first air vent of the support frame, the air guiding function in the downward air outlet state is achieved. This solves the problem of ineffective air outlet in the open area caused by rotating the decorative panel to achieve left and right air sweeping in the downward air outlet state. Furthermore, the decorative panel can switch between a first position with the first air vent of the support frame assembly closed and a second position with the first air vent open. In this way, the open area always corresponds to the first air vent in the downward air outlet state, and their relative positions do not change, effectively ensuring the air volume in the downward air outlet state. In addition, the closed area corresponding to the first air vent in the downward air outlet mechanism's non-air outlet state seals the first air vent, achieving consistency in the overall structure of the air conditioning device and improving its aesthetics.

[0032] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following implementation methods and examples can be combined with each other.

[0033] This embodiment proposes a bottom air outlet mechanism 100, which is applied to an air conditioning device, such as an air conditioner, humidifier, or dehumidifier. The bottom air outlet mechanism 100 includes a chassis 1, a support frame assembly 3, and a decorative panel assembly 2.

[0034] Specifically, such as Figures 2-6 As shown, the chassis 1 has a disc-shaped main body 11, the support frame assembly 3 is disposed on the disc-shaped main body 11 and fixedly connected to the disc-shaped main body 11, and the decorative panel assembly 2 is disposed on the disc-shaped main body 11 and can rotate in the circumferential direction of the disc-shaped main body 11.

[0035] In a preferred embodiment, refer to Figure 2 and Figure 4 The chassis 1 also includes a baffle 12, which is disposed on the disc-shaped body 11 and located near the outer edge of the disc-shaped body 11. The baffle 12 extends along the circumferential direction of the chassis 1 body and encloses a portion of the circumferential area of ​​the disc-shaped body 11 to form a chassis vent 13 on the disc-shaped body 11.

[0036] Reference Figure 4 The chassis 1 also includes a limiting boss 15, which is located on the disc-shaped body 11. The limiting boss 15 includes an arc-shaped limiting wall, at least a portion of which is correspondingly provided with the baffle 12. A limiting track 16 is formed between the baffle 12 and the arc-shaped limiting wall. At least a portion of the decorative panel assembly 2 is located within the limiting track 16. During the rotation of the decorative panel assembly 2 along the circumferential direction of the disc-shaped body 11, the limiting track 16 radially limits the decorative panel assembly 2.

[0037] The support frame assembly 3 includes a support frame body 31 and an air guide plate 32. The support frame body 31 is provided with a first air vent 312. The air guide plate 32 is rotatably disposed on the support frame body 31 and located inside the first air vent 312.

[0038] Specifically, refer to Figure 4 The support frame body 31 is a frame structure, and the support frame body 31 includes at least two support side plates and a support top plate. The two support side plates are arranged relatively apart, and the support top plate is located at the top of the two support side plates and connected to the two support side plates. The bottom ends of the two support side plates are directly set on the disc-shaped body 11. The two support side plates, the support top plate, and the disc-shaped body 11 enclose and form a first air vent 312. Alternatively, the bottom ends of the two support side plates are connected to the disc-shaped body 11 through a support bottom plate, and the two support side plates, the support top plate, and the support bottom plate are connected together.

[0039] In a preferred embodiment, refer to Figure 4 The supporting top plate is an arc-shaped plate that matches the curvature of the disc-shaped main body 11, so as to reduce the volume of the supporting frame main body 31 and avoid interfering with the rotation of the decorative panel assembly 2.

[0040] The air guide plate 32 includes multiple air guide blades arranged along the height direction of the support frame body 31. The upper ends of the multiple air guide blades are rotatably connected to the top support plate, and the lower ends of the multiple air guide blades are rotatably connected to the disc-shaped body 11, or rotatably connected to the bottom support plate of the support frame body 31. The support frame assembly 3 also includes an air guide plate motor 33. The top support plate is provided with a mounting groove for mounting the air guide plate motor 33. The air guide plate motor 33 is used to drive the air guide blades to swing left and right in the air outlet state of the lower air outlet mechanism 100, so as to realize the left and right sweeping air in the air outlet state of the lower air outlet mechanism 100, which solves the problem of partially ineffective air outlet caused by the rotation of the decorative plate 211 to achieve the sweeping function.

[0041] Reference Figure 2 The decorative panel assembly 2 is disposed on the disc-shaped body 11 and can rotate in the circumferential direction of the disc-shaped body 11. The decorative panel assembly 2 can be disposed on the inner side of the disc-shaped body 11 and circumferentially disposed on the disc-shaped body 11, or the decorative panel assembly 2 can be disposed on the outer edge of the chassis 1 and sleeved on the outer side of the disc-shaped body 11 in the circumferential direction.

[0042] The decorative panel assembly 2 includes a decorative panel 211 extending along the circumferential and height directions of the chassis 1. The decorative panel 211 includes a closed area 212 and an open area 213. The closed area 212 is a smooth wall surface of the decorative panel 211, and the open area 213 is an opening structure formed in the decorative panel 211.

[0043] In a preferred embodiment, the open area 213 includes an air outlet grille 2131 disposed within the opening structure to disperse the concentrated airflow blown out by the first air outlet 312 into multiple smaller airflows, so that the air enters the room more evenly and avoids the situation of excessive or insufficient local airflow, thereby improving the comfort of indoor air conditioning.

[0044] The decorative panel 211 has a first rotational position that aligns the closed area 212 with the first air vent 312, closing the first air vent 312, and a second rotational position that aligns the open area 213 with the first air vent 312, opening the first air vent 312. The decorative panel 211 is controlled to switch between the first and second rotational positions. Thus, when the lower air outlet mechanism 100 is in the air outlet state, the decorative panel 211 opens the first air vent 312 through the open area 213. Furthermore, it optimizes the situation where the positions of the open area 213 and the first air vent 312 do not change when the lower air outlet mechanism 100 is in the air outlet state, thereby further ensuring airflow. When the lower air outlet mechanism 100 is not in the air outlet state, the first air vent 312 is closed through the closed area 212, and the closed area 212 has a smooth wall surface, ensuring the consistency of the overall appearance structure, improving aesthetics, and preventing external dust from entering the first air vent 312.

[0045] Preferably, the shape and size of the closed area 212 and the open area 213 should be adapted to the first air vent 312, or the size of the closed area 212 and the open area 213 should be larger than the first air vent 312, so that the first air vent 312 is completely closed when the decorative panel 211 is in the first rotation position and the first air vent 312 is completely opened when the decorative panel 211 is in the second rotation position.

[0046] Figure 7a This is a simulation cloud map of the airflow at the bottom air outlet mechanism 100 of the air conditioner indoor unit in the background technology. Figure 7b This is a simulation cloud map of the airflow at the bottom air outlet mechanism 100 of the air conditioner indoor unit in this application. According to... Figure 7a and Figure 7b It can be seen that the air volume of the indoor unit of the air conditioner in this application in the downward air outlet state is significantly greater than that of the indoor unit of the air conditioner in the prior art in the downward air outlet state. Therefore, it can be seen that the downward air outlet mechanism 100 of this application can significantly improve the downward air outlet volume.

[0047] In one possible implementation, such as Figures 2-4 As shown, the decorative panel 211 covers a portion of the circumferential area of ​​the disc-shaped main body 11. The decorative panel 211 and the uncovered area of ​​the disc-shaped main body 11 form a non-closed spatial structure. At this time, the decorative panel 211 is an arc-shaped plate, which can reduce the material consumption of the decorative panel 211 and reduce the weight of the whole machine, thereby reducing production costs.

[0048] In one possible implementation, the top of the support frame body 31 is slidably connected to the top of the decorative panel 211. The support frame body is provided with one of a first roller and a first roller track, and the decorative panel is provided with the other of a first roller and a first roller track, the first roller being capable of rolling along the first roller track.

[0049] Since the decorative panel 211 is an arc-shaped plate with a small circumferential dimension, there is a problem of poor stability when the decorative panel 211 rotates along the circumferential direction of the disc-shaped main body 11. In this embodiment, a rolling assembly is set between the top of the decorative panel 211 and the top of the support frame main body 31 to improve the stability of the decorative panel 211 during rotation, and at the same time, it can effectively avoid the problem of the decorative panel 211 shaking when the air is vented.

[0050] For example, refer to Figure 4 and Figure 5 Multiple first rollers 51 are rotatably disposed on the top of the decorative panel 211 and spaced apart along the circumferential extension direction of the decorative panel 211 in the disc-shaped body 11. A first roller track 52 is disposed on the top of the support frame body 31 near the decorative panel 211, and the trajectory of the first roller track 52 is adapted to the curvature of the top of the decorative panel 211. Preferably, the first roller track 52 is a downward-facing groove, and the top of the decorative panel 211 engages with the first roller track 52. This achieves sliding engagement between the first rollers 51 and the first roller track 52, and ensures the reliability of the sliding connection between the support frame body 31 and the decorative panel 211.

[0051] In addition, since the support frame body 31 where the first roller track 52 is located is directly fixedly assembled on the disc-shaped body 11, the error accumulated from indirect assembly can be avoided, which can lead to abnormal running gaps and cause jamming or stuttering problems.

[0052] In other possible implementations, when the decorative panel 211 is arranged along the circumferential direction of the disc-shaped body 11 and forms a closed ring structure, the top of the decorative panel 211 is slidably connected to the top of the support frame body 31, which also improves the rotational stability of the decorative panel 211.

[0053] In this embodiment, the first roller track 52 can be set independently of the support frame body 31, and can be connected to the support frame body 31 by one of the following methods: snap-fit, plug-in, connector, or adhesive; or it can be integrally formed with the support frame body 31.

[0054] In one possible implementation, such as Figure 5As shown, the disc-shaped main body 11 is provided with a chassis air duct 14, and the support frame main body 31 has an air inlet end and an air outlet end. The air inlet end is sealed to the outlet end of the chassis air duct 14 to form an extension of the chassis air duct 14. The airflow from the chassis air duct 14 will be directly discharged from the first air outlet 312. The air inlet end is sealed to the outlet section of the chassis air duct 14 to prevent the airflow in the chassis air duct 14 from flowing out through the gap between the support frame main body 31 and the chassis air duct 14, thereby effectively ensuring the airflow volume.

[0055] In one possible implementation, such as Figure 4 As shown, the decorative panel assembly 2 includes an outer ring layer 21 and an inner ring layer 22. The outer ring layer 21 is fitted over the inner ring layer 22 and fixedly connected to it. The decorative panel 211 is located on the outer ring layer 21. A second air vent 221 is provided at the position corresponding to the open area 213 of the inner ring layer 22. This ensures the maximum overlap between the open area 213 and the first air vent 312 when the open area 213 rotates to correspond with the first air vent 312, thereby further ensuring the airflow. This embodiment, by adopting a decorative panel assembly 2 with a double-layer structure including an outer ring layer 21 and an inner ring layer 22, can improve the stability of the decorative panel assembly 2 in the overall rotation state, while also improving the structural strength and the reliability of the assembly between the decorative panel assembly 2 and the chassis 1.

[0056] In one possible implementation, such as Figure 4 As shown, the lower air outlet mechanism 100 also includes a drive mechanism for driving the decorative panel assembly 2 to rotate. The drive mechanism includes a drive motor 61, a gear 62, and a rack 63. The drive motor 61 is mounted on the chassis 1, the gear 62 is driven by the drive motor 61, and the rack 63 is located on the side of the inner ring 22 opposite to the outer ring 21, meshing with the gear 62. In the prior art, to ensure that the decorative panel 211 can rotate and accelerates the transmission with less effort, the drive mechanism usually adopts a two-stage transmission method. However, this two-stage transmission method will lead to increased play (moveability). When the decorative panel 211 frequently swings back and forth to sweep the air, coupled with the strong air outlet effect, there is a tendency for obvious vibration and abnormal noise. The drive mechanism of this embodiment adopts a single-stage transmission and maintains the same transmission ratio as the two-stage transmission, thereby effectively reducing play and avoiding obvious vibration and abnormal noise problems.

[0057] In one possible implementation, a rolling assembly is provided between the chassis 1 and the decorative panel assembly 2; The rolling assembly includes a second roller and a second roller track. The chassis is provided with one of the second roller and the second roller track, and the decorative panel assembly is provided with the other of the second roller and the second roller track. The second roller is capable of rolling along the second roller track. In this embodiment, by providing the second roller 42 assembly, the reliability and stability of rotation between the decorative panel assembly 2 and the chassis 1 can be improved.

[0058] And / or, the rolling assembly includes balls and ball tracks, the chassis is provided with one of the balls and ball tracks, the trim assembly is provided with the other of the balls and ball tracks, and the balls are capable of rolling along the ball tracks.

[0059] Since the ball bearing 41 can roll in all directions, by setting the ball bearing 41 between the decorative panel assembly 2 and the chassis 1, the problem of side slipping and abnormal noise caused by the rollers only rolling in one direction when the decorative panel assembly 2 is supported vertically by the rollers can be avoided.

[0060] In one example, refer to Figure 4 and Figure 6 The rolling assembly includes multiple balls 41 and multiple second rollers 42. The balls 41 are disposed on the disc-shaped body 11, and some of the second rollers 42 are disposed on the disc-shaped body 11 and some on the baffle wall 12. The multiple second rollers 42 and balls 41 disposed on the disc-shaped body 11 are alternately arranged along the circumferential direction of the disc-shaped body 11, thereby ensuring circumferential rotation of the decorative panel assembly 2 while avoiding lateral slippage. Adjacent balls 41 and second rollers 42 are staggered along the radial direction of the disc-shaped body 11, thus preventing interference between the positions of the ball 41 tracks and the roller tracks.

[0061] The ball bearing track 41 and the second roller track 43 are located at positions on the outer ring layer 21 and / or the inner ring layer 22 corresponding to the ball bearing 41 and the roller. The ball bearing track 41 can be a smooth wall surface along the circumferential direction of the disc-shaped body 11, or a groove along the circumferential direction of the base 1. The second roller track 43 is a groove along the circumferential direction of the base 1. The ball bearing track 41 and the second roller track 43 can be independently set on the outer ring layer 21 and / or the inner ring layer 22, and connected to the outer ring layer 21 and / or the inner ring layer 22 through a snap-fit, plug-in, connector, or adhesive method, or they can be integrally formed with the outer ring layer 21 and / or the inner ring layer 22.

[0062] This embodiment also provides a cabinet-type air conditioner indoor unit, such as... Figure 8 and Figure 9 As shown, the indoor unit of the cabinet air conditioner includes a housing 200, a main air duct, and the lower air outlet mechanism 100 mentioned above. The bottom end of the housing 200 is connected to the lower air outlet mechanism 100, and the main air duct is located inside the housing 200 and connected to the first air outlet 312.

[0063] In this embodiment, when the air outlet mechanism 100 is in the air-discharging state, the decorative panel assembly 2 rotates to a second rotation position that opens the first air vent 312 and then stops rotating, ensuring the air volume in the air-discharging state. Simultaneously, by separating the air guide plate 32 from the decorative assembly and fixing it to the chassis 1, the air guide plate 32 does not rotate with the decorative panel 211, thus achieving air sweeping in the air-discharging state. When the air outlet mechanism 100 is not discharging air, the decorative panel assembly 2 rotates to a first rotation position to close the first air vent 312, preventing external dust from entering and maintaining the aesthetic appearance of the entire unit.

[0064] In one possible implementation, the outer casing 200 includes a first outer casing portion 201, a second outer casing portion 202, and a third outer casing portion 203 arranged circumferentially along the disc-shaped main body 11. The bottom ends of the first outer casing portion 201 and the third outer casing portion 203 are connected to the disc-shaped main body 11, and the bottom end of the second outer casing portion 202 is connected to the top end of the support frame main body 31. Thus, the lower parts of the first outer casing portion 201 and the second outer casing portion 202 cover the area of ​​the chassis 1 circumferentially. The bottom ends of the first outer casing portion 201 and the second outer casing portion 202, the second outer casing portion 202, and the disc-shaped main body 11 enclose a downwind opening, which corresponds to and avoids the first air vent 312. The size of the open area 213 and / or the closed area 212 is greater than or equal to the downwind opening, so as to achieve complete opening or complete closure of the downwind opening.

[0065] When the decorative panel 211 is in the second rotating position, such as Figure 8 As shown, the open area 213 is located at the leeward opening. Opening the leeward opening allows air to exit through the first vent 312, at which point the closed area 212 is blocked by the second outer casing 202. When the decorative panel 211 is in the first rotating position, as... Figure 9 As shown, the enclosed area 212 is located at the downwind end, and the enclosed area 212 and the second outer shell 202 form a smooth plane. At this time, the open area 213 is blocked by the first outer shell 201 to ensure the consistency of appearance.

[0066] This embodiment also proposes a control method for a cabinet-type air conditioner indoor unit. The control method is applied to the cabinet-type air conditioner indoor unit mentioned above, and the control method includes: When the lower air outlet mechanism 100 is in the air outlet state, the control decorative panel 211 is in the second rotation position; When the lower air outlet mechanism 100 is in a non-air outlet state, the control decorative panel 211 is in the first rotation position.

[0067] The control method of the cabinet air conditioner indoor unit in this embodiment has similar technical effects to the corresponding features of the cabinet air conditioner indoor unit, and will not be described again here.
