Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a dual air guide plate assembly and an air conditioner. Background Technology

[0002] Nowadays, air conditioners have become an indispensable household appliance in people's daily lives, especially during the hot summer months when their usage is extremely high. Most families have air conditioners installed in both their living rooms and bedrooms. Traditional air conditioners typically have an air outlet at the bottom of the front panel of the indoor unit. Airflow is adjusted vertically by controlling the rotation of a guide vane located at the outlet. However, this airflow method only delivers air along the side of the outlet, resulting in a narrow airflow range and limiting the choice of installation location for the indoor unit. Furthermore, the single-outlet design leads to a slow response time for adjusting indoor temperature, failing to meet the diverse needs of users.

[0003] Therefore, existing technology discloses an air conditioner with dual air guide plates, comprising an air guide assembly and a square-structured middle frame assembly. The middle frame assembly has a first air outlet and a second air outlet, the first air outlet facing a different direction than the second air outlet. The air guide assembly is installed in the first and second air outlets to adjust the airflow direction of the indoor unit of the air conditioner. The air guide assembly includes a first air guide plate and a second air guide plate. The first air guide plate is rotatably installed in the first air outlet, and the second air guide plate is rotatably installed in the second air outlet. Thus, the rotational cooperation of the first and second air guide plates can achieve various airflow modes in different directions to improve the user experience.

[0004] However, the second air guide plate in the aforementioned air conditioner is generally small in size and has low structural strength. After the air conditioner has been used for a long time, the second air guide plate is prone to deformation due to frequent rotation, which causes gaps to form between the second air guide plate and the first air guide plate. Air leakage will frequently occur at the gaps, affecting the air outlet direction of the air conditioner and impacting the user experience. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above in the prior art, the present invention provides a dual air guide plate assembly and an air conditioner. The suspension structure enhances the structural strength and connection reliability of the first and second air guide plates, thereby preventing deformation and ensuring the normal operation of the air conditioner in various air supply modes, thus ensuring the user experience.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A dual air guide plate assembly, comprising:

[0008] An air guide assembly includes a first air guide plate and a second air guide plate that are rotatably coaxial. The first air guide plate and the second air guide plate are arranged adjacent to each other, and in the initial state, the corresponding end faces of the first air guide plate and the second air guide plate are in contact.

[0009] The suspension structure includes a shaft, a first hanger, and a second hanger. The shaft is located on the rotation axis of the first and second air guide plates. The first hanger is fixed to the first air guide plate and rotatably sleeved on the shaft. The second hanger is fixed to the second air guide plate and rotatably sleeved on the shaft.

[0010] In a preferred embodiment, the first air guide plate and the second air guide plate are arranged correspondingly in length, the shaft is located in the middle of the extension direction of the rotation axis, and the first hanger and the second hanger are spaced apart and sleeved in the middle of the extension direction of the shaft.

[0011] In a preferred embodiment, in this utility model, the shaft extends axially to correspond to the first air guide plate and the second air guide plate, and the corresponding first and second hanger rods are arranged in multiple groups at intervals along the length of the shaft.

[0012] In a preferred embodiment, in this invention, multiple sets of suspension rods are arranged at equal intervals, and the interval between the first suspension rod and the second suspension rod in the multiple sets of suspension rods is equal.

[0013] In a preferred embodiment of the present invention, the first air guide plate and the second air guide plate can rotate relative to each other or rotate synchronously, and the first air guide plate and the second air guide plate are driven by two motors respectively.

[0014] In a preferred embodiment, the dual air guide plate assembly further includes a middle frame, which has a first air outlet and a second air outlet. The first air outlet and the second air outlet are arranged adjacent to each other and have different orientations. The first air guide plate is rotatably installed at the first air outlet, and the second air guide plate is rotatably installed at the second air outlet.

[0015] In a preferred embodiment of the present invention, a third hanger is provided in the middle frame corresponding to the first hanger and the second hanger. The third hanger is sleeved on the shaft and is rotatably connected to the shaft.

The panel can be moved away from the air outlet surface to open the first air outlet and is spaced apart from the air outlet surface.

[0018] An air conditioner includes: a dual air guide plate assembly.

[0019] The beneficial effects of the dual air guide plate assembly and air conditioner provided by this utility model are as follows:

[0020] The air guide assembly is equipped with a suspension structure.

[0031] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] 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.

[0034] Example 1

[0035] See Figure 2-4 This embodiment provides a dual air guide plate assembly, including an air guide assembly 1. The air guide assembly 1 includes a first air guide plate 11 and a second air guide plate 12 that are rotatably coaxial. The first air guide plate 11 and the second air guide plate 12 are arranged adjacent to each other, and in the initial state, the corresponding end faces of the first air guide plate 11 and the second air guide plate 12 are in contact.

[0036] In this embodiment, as Figure 2 As shown, the first air guide plate 11 and the second air guide plate 12 are arranged vertically. In the initial state, the bottom surface of the first air guide plate 11 is in close contact with the top surface of the second air guide plate 12 so that the air outlet of the air conditioner can be closed when the air guide assembly 1 is applied in the air conditioner.

[0037] The first air guide plate 11 and the second air guide plate 12 are prone to deformation due to frequent rotation over a long period of time, which can cause gaps to form between the second air guide plate 12 and the first air guide plate 11. Frequent air leakage will occur at the gaps, affecting the air outlet direction of the air conditioner and impacting the user experience.

[0038] Therefore, the dual air guide plate assembly of this embodiment includes a hanging structure 2. The hanging structure 2 includes a shaft 21, a first hanging rod 22 and a second hanging rod 23. The shaft 21 is located on the rotation axis of the first air guide plate 11 and the second air guide plate 12. The first hanging rod 22 is fixed to the first air guide plate 11 and rotatably sleeved on the shaft 21. The second hanging rod 23 is fixed to the second air guide plate 12 and rotatably sleeved on the shaft 21.

[0039] The air guide assembly 1 is equipped with a hanging structure 2. The shaft 21 of the hanging structure 2 is located on the rotation axis of the air guide assembly 1 to ensure that the first air guide plate 11 and the second air guide plate 12 can rotate normally. The first air guide plate 11 is suspended from the shaft 21 by the first hanging rod 22, and the second air guide plate 12 is suspended from the shaft 21 by the second hanging rod 23. This not only improves the structural strength of the first air guide plate 11 and the second air guide plate 12, but also avoids deformation problems caused by long-term rotation. This ensures the reliability of the positional relationship between the first air guide plate 11 and the second air guide plate 12, prevents gaps from causing air leakage, ensures the normal operation of various air supply modes of the air conditioner, and thus ensures the user experience.

[0040] Furthermore, the first air guide plate 11 and the second air guide plate 12 are correspondingly arranged in length, the shaft 21 is located in the middle of the extension direction of the rotation axis, and the first suspension rod 22 and the second suspension rod 23 are spaced apart and sleeved in the middle of the extension direction of the shaft 21. The suspension structure 2 is located in the middle of the length direction of the air guide assembly 1, which makes the structural strength of the air guide assembly 1 more uniform and the stress more uniform, which is more conducive to avoiding deformation.

[0041] The shaft 21 extends axially to correspond to the first air guide plate 11 and the second air guide plate 12. Multiple sets of suspension rods, consisting of the first suspension rod 22 and the second suspension rod 23, are spaced apart along the length of the shaft 21. The arrangement of multiple suspension structures 2 helps to improve the structural strength of the air guide assembly 1 from all directions, thereby ensuring the reliability of the positional relationship between the first air guide plate 11 and the second air guide plate 12.

[0042] Furthermore, multiple sets of suspension rods are evenly spaced, with the first suspension rod 22 and the second suspension rod 23 in each set being equally spaced. This evenly spaced suspension structure ensures that the first air guide plate 11 and the second air guide plate 12 are uniformly strengthened from all directions, essentially eliminating the possibility of deformation. The spacing between the first suspension rod 22 and the second suspension rod 23 prevents mutual interference between the rotation of the first air guide plate 11 and the second air guide plate 12, thereby improving the smoothness and accuracy of rotation.

[0043] Based on the above structure, the dual air guide plate assembly also includes a middle frame 3. The middle frame 3 has a first air outlet 31 and a second air outlet 32. The first air outlet 31 and the second air outlet 32 ​​are arranged adjacent to each other and have different orientations. The first air guide plate 11 is rotatably installed in the first air outlet 31, and the second air guide plate 12 is rotatably installed in the second air outlet 32. An air supply assembly is provided inside the middle frame 3 to deliver air from the first air outlet 31 and the second air outlet 32.

[0044] The middle frame 3 is provided with a third hanger 24 corresponding to the first hanger 22 and the second hanger 23. The third hanger 24 is sleeved on the shaft 21 and is rotatably connected to the shaft 21. The setting of the third hanger 24 further improves the structural strength and installation reliability of the suspension structure for the air guide assembly 1, and makes the position of the first air guide plate 11 and the second air guide plate 12 more accurate.

[0045] The number of third hangers 24 is equal to that of the first hangers 22 and the second hangers 23, and their positions correspond one-to-one. The spacing between adjacent pairs of the corresponding first hangers 22, second hangers 23, and third hangers 24 is equal. The relative positional relationship between each part of the first air guide plate 11 and the second air guide plate 12 along the length direction and the middle frame 3 is the same, ensuring the structural stability of the double air guide plate assembly.

[0046] In addition, the first air guide plate 11 and the second air guide plate 12 are both located in the air outlet of the middle frame 3. The air outlet surface 33 of the air outlet is provided with a panel 5. In the initial state, the panel 5 overlaps with the projection of the first air guide plate 11 on the air outlet surface. The panel 5 can be moved away from the air outlet surface to open the first air outlet 31 and is spaced apart from the air outlet surface.

[0047] In this embodiment, the air outlet of the middle frame 3 is located at the front, and the first air outlet 31 and the second air outlet 32 ​​are located at the lower part of the air outlet and are vertically arranged. The air outlet surface 33 is located on the front end face of the middle frame 3, the first air outlet 31 is located at the lower part of the air outlet surface 33, and the second air outlet 32 ​​is located below the air outlet surface 33 and the two are vertically connected. The panel 5 is located on the front side of the air outlet surface 33 and can be driven to move forward and upward relative to the air outlet surface 33 and return to its original position.

[0048] Meanwhile, the first air guide plate 11 and the second air guide plate 12 can rotate relative to each other or rotate synchronously. The first air guide plate 11 and the second air guide plate 12 are driven by two motors 4 respectively.

[0049] Thus, when the dual air guide vane assembly of this embodiment is applied in an air conditioner, the air conditioner has the following states:

[0050] See Figure 5The first air guide plate 11 of the air conditioner is vertically arranged to close the first air outlet 31, and the second air guide plate 12 of the air conditioner is horizontally arranged to close the second air outlet 32. The panel 5 is located on the front side of the air outlet surface 33, and the panel 5 and the first air guide plate 11 overlap in the orthographic projection of the air outlet surface 33 to avoid air leakage. At this time, the air conditioner is in the off state.

[0051] See Figure 6 Compared to Figure 5 The second air guide plate 12 remains in the same position, while the first air guide plate 11 rotates 90° clockwise to a horizontal position. The panel 5 is driven forward and upward to create a gap between the periphery of the panel 5 and the middle frame 3. At this time, the first air guide plate 11 divides the first air outlet 31 into upper and lower parts to split the horizontal airflow. A portion of the airflow flows upward, left, and right along the gap between the panel 5 and the air outlet surface 33 to achieve four-way airflow. In this state, the air conditioner is in four-way airflow mode, resulting in more uniform airflow and facilitating faster changes in indoor temperature uniformity.

[0052] See Figure 7 Compared to Figure 5 With panel 5 remaining unchanged, the first air guide plate 11 rotates clockwise by less than 90°, and the second air guide plate 12 rotates counterclockwise by the same angle as the first air guide plate 11, so that the first air guide plate 11 and the second air guide plate 12 are parallel and tilted downwards at intervals, thereby achieving diverted and tilted airflow. At this time, the air conditioner is in a tilted airflow state, and the airflow passes through the double guidance of the first air guide plate 11 and the second air guide plate 12, which helps to improve the diffusion of the airflow and thus accelerate the temperature change.

[0053] See Figure 8 Compared to Figure 5 With panel 5 remaining unchanged, the first air guide plate 11 rotates 180° clockwise, and the second air guide plate 12 rotates 90° clockwise, so that the first air guide plate 11 and the second air guide plate 12 are parallel and perpendicular downwards, thereby achieving downward airflow. At this time, the air conditioner is in a downward airflow state, and the airflow passes through the double guidance of the first air guide plate 11 and the second air guide plate 12, which helps to improve the diffusion of the airflow and thus accelerate the temperature change.

[0054] Example 2

[0055] See Figure 1 This embodiment provides an air conditioner, which includes the dual air guide plate assembly of Embodiment 1. Applying the dual air guide plate assembly of Embodiment 1 to an air conditioner enables multiple air supply modes, such as four-way air outlet mode, inclined air outlet mode, and downward air outlet mode.

[0056] Because the dual air guide plate assembly is equipped with a hanging structure 2, it not only improves the structural strength of the first air guide plate 11 and the second air guide plate 12, but also avoids the deformation problem caused by long-term rotation. This ensures the reliability of the positional relationship between the first air guide plate 11 and the second air guide plate 12, and prevents gaps from causing air leakage. This, in turn, ensures the normal operation of the air conditioner's various air supply modes and the user experience.

[0057] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
