Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to a three-dimensional air guide component and a top-mounted air conditioning indoor unit. Background Technology

[0002] A ceiling-mounted air conditioner indoor unit, also known as a ceiling-mounted air conditioner, recessed ceiling air conditioner, or ceiling-mounted air conditioner, is an air conditioning system installed on the indoor ceiling. Specifically, a ceiling-mounted air conditioner indoor unit includes a casing and an air guide panel located below the casing. The casing is installed in an embedded manner within the indoor ceiling. The air guide panel has air outlets and return air inlets. The casing houses a fan and a heat exchanger, which blows cool or warm air through the air outlets on the air guide panel into the indoor space, thereby achieving the purpose of regulating indoor temperature, humidity, and ventilation.

[0003] The advantages of a roof-mounted air conditioner indoor unit are:

[0004] (1) Saves space: Installed in the ceiling, it does not occupy floor and wall space, making the interior space more open;

[0005] (2) Uniform air supply: It usually adopts a multi-directional air supply design, so that hot and cold air can be evenly distributed throughout the room, providing a comfortable temperature environment;

[0006] (3) Quiet design: It usually has a complete quiet design, with low operating noise, which can ensure a quieter indoor environment;

[0007] (4) Multifunctional: It is easy to integrate electric heating, air purification, dehumidification and other functions, and is suitable for use under various climatic conditions.

[0008] Currently, in pursuit of a gentle and comfortable airflow, manufacturers typically design the air guide panel of the indoor unit of a top-mounted air conditioner as follows: the center of the panel is set as the return air inlet, and four air outlets are set around the return air inlet. Each air outlet is equipped with an air guide plate, which can achieve airflow in four directions and more uniform air temperature.

[0009] However, in current market, the air outlet and return air inlet of ceiling-mounted air conditioner indoor units are both located on a single panel, on the same plane and close together. This results in low air delivery efficiency during cooling and heating, mainly because the air blown out by the air outlet is directly drawn back into the return air grille. Figure 1 As shown by the middle arrow, this causes a short circuit in the gas flow field, resulting in some of the blown-out cold and hot air being recycled before it can act on the indoor space. Therefore, the cooling and heating performance is poor, especially in cooling mode. Utility Model Content

[0016] As a specific technical solution, each air supply channel corresponds to a set of air supply channel limiting plates. Each set of air supply channel limiting plates includes a pair of first limiting plates and a pair of second limiting plates. The pair of first limiting plates is used to limit a first air outlet path between the air inlet and the first air outlet, and the pair of second limiting plates is used to limit a second air outlet path between the air inlet and the second air outlet.

[0017] As a specific technical solution, the first air guide plate assembly includes a first air guide plate and a first driving mechanism.

[0021] The second objective of this invention is to provide a top-mounted air conditioning indoor unit that improves air delivery efficiency and flexibility.

[0022] The second objective of this utility model is achieved by the following technical solution:

By transforming the existing single-panel air guide panel into a three-dimensional air guide frame, various types of air outlets can be opened to achieve three-dimensional air guidance. In specific use, the supplied air volume enters from the air inlet and can be discharged through the first air outlet and / or the second air outlet, thereby achieving flexible control of downward and / or sideways airflow. Moreover, when all or part of the airflow is selected for sideways airflow, the distance between the second air outlet and the return air outlet is large and the directional angle interval is large, significantly reducing the situation where the air is retracted immediately after being discharged, resulting in a significant improvement in air supply efficiency compared to existing technologies. The roof-mounted air conditioner indoor unit provided by the above-mentioned technical solution of this utility model, by cooperating with the chassis of the existing roof-mounted air conditioner indoor unit, achieves flexible air supply while improving cooling or heating efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "setting," "fixing," and "assembly," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0043] like Figure 2 As shown, this utility model provides a three-dimensional air guide assembly 100, which can be used as a standard accessory to cooperate with the casing 200 of an existing roof-mounted air conditioner indoor unit. See [reference needed]. Figure 5 As shown, this design achieves flexible air delivery while improving cooling or heating efficiency. The specific structure of this three-dimensional air guide assembly is described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] See Figure 2 and Figure 3 As shown, the three-dimensional air guiding assembly 100 provided in this embodiment includes an air guiding frame 10. The air guiding frame 10 has a vertically penetrating return air inlet 101 in the middle. An air supply channel is provided on the side wall 102 of the return air inlet 101. The air supply channel has: an air inlet 121 opened on the upper end face of the side wall 102, a first air outlet 122 opened on the lower end face of the side wall 102, and a second air outlet 123 opened on the outer side of the side wall 102. The air inlet 121, the first air outlet 122, and the second air outlet 123 are connected to each other.

[0045] The above embodiment achieves three-dimensional air guidance by setting the existing single-panel air guide panel as a three-dimensional air guide frame, and opening the first air outlet 122 on the lower end face of the side panel 102 and the second air outlet 123 on the outer side face of the side panel 102. In specific use, the supplied air volume enters the air supply channel from the air inlet 121. The user can choose to discharge cold air or hot air from the first air outlet 122 and / or the second air outlet 123, thereby achieving flexible control of downward and / or side air outlets. Moreover, when all or part of the side air outlets are selected, since the second air outlet 123 is far from the return air outlet 101 and the directional angle is large, the situation of air being reclaimed immediately after being discharged can be significantly reduced, and the air supply efficiency is significantly improved compared with the prior art.

[0046] See also Figure 2 and Figure 3 As shown, in this embodiment, the side circumference 102 of the air guide frame 10 is a square ring structure, and the air supply channels are respectively provided on the four sides of the side circumference 102. As another feasible implementation, the side circumference 102 of the air guide frame 10 can also be a circular ring structure. In this case, the return air inlet 101 is circular, the side circumference is circular, and multiple air supply channels are provided on the side circumference at equal angles.

[0047] See also Figure 2 and Figure 3 As shown, in this embodiment, the side panel 102 includes an upper panel 11, a lower panel 12, an inner peripheral support plate 13, and an air supply channel limiting plate. The upper panel 11 and the lower panel 12 are respectively provided with central openings. The inner peripheral support plate 13 is longitudinally supported between the edge of the central opening of the upper panel and the edge of the central opening of the lower panel, thereby forming the return air vent 101. At the same time, the upper panel 11 and the lower panel 12 are arranged parallel to each other and spaced apart vertically. In addition, the air supply channel limiting plate is disposed between the upper panel 11 and the lower panel 12 and restricts the air supply channel.

[0048] Specifically, each air supply duct corresponds to a set of air supply duct limiting plates, and each set of air supply duct limiting plates includes a pair of first limiting plates 141 and a pair of second limiting plates 142; each pair of first limiting plates 141 is used to limit a first air outlet path between the corresponding air inlet 121 and the first air outlet 122, and each pair of second limiting plates 142 is used to limit a second air outlet path between the corresponding air inlet 121 and the second air outlet 123.

[0049] See also Figure 2 and Figure 3 As shown in this embodiment, each first air outlet 122 is provided with a first air guide plate assembly 20 with an adjustable air outlet angle, and each second air outlet 123 is provided with a second air guide plate assembly 30 with an adjustable air outlet angle.

[0050] The first air guide plate assembly includes a first air guide plate and a first driving mechanism. The two ends of the first air guide plate are rotatably mounted on a pair of first limiting plates, and the first driving mechanism drives the first air guide plate to rotate. The second air guide plate assembly includes a second air guide plate and a second driving mechanism. The two ends of the second air guide plate are rotatably mounted on a pair of second limiting plates, and the second driving mechanism drives the second air guide plate to rotate.

[0051] Based on this, the three-dimensional air guide assembly provided in this embodiment can operate in the following modes:

[0052] (1) Simple downward exhaust: The first air guide plate assembly 20 opens the first air outlet 122, and the second air guide plate assembly 30 closes the second air outlet 123, combined with Figure 7 As shown;

[0053] (2) Simple lateral exhaust: The first air guide plate assembly 20 closes the first air outlet 122, and the second air guide plate assembly 30 opens the second air outlet 123; see also Figure 3 and Figure 6 As shown, the first air guide plate of the first air guide plate assembly 20 is horizontal, at which time the first air outlet 122 is closed; at the same time, the second air guide plate assembly 30 is also horizontal, at which time the second air outlet 123 is opened.

[0054] (3) Simultaneous side and downward exhaust: the first air guide plate assembly 20 opens the first air outlet 122, and the second air guide plate assembly 30 opens the second air outlet 123;

[0055] (4) Close the non-exhaust air: the first air guide plate assembly 20 closes the first air outlet 122, and the second air guide plate assembly 30 closes the second air outlet 123;

[0056] In the above modes (1), (2), and (3), the opening and closing of the first air outlet 122 and the second air outlet 123 and the exhaust angle can be specifically controlled by the first air guide plate assembly 20 and the second air guide plate assembly 30.

[0057] In another feasible implementation, the side panel 102 includes an upper panel 11, a lower panel 12, an inner peripheral support plate 13, and an outer peripheral support plate. The upper panel 11 and the lower panel 12 are respectively provided with central openings. The inner peripheral support plate 13 is longitudinally supported between the inner peripheries of the upper panel 11 and the lower panel 12, and the outer peripheral support plate is longitudinally supported between the outer peripheries of the upper panel 11 and the lower panel 12, so that the upper panel 11 and the lower panel 12 are arranged parallel to each other and spaced apart vertically. A second air outlet is opened on the outer peripheral support plate. In this implementation, it is not necessary to provide an air supply channel limiting plate for forming a dedicated air supply channel, but the space between the inner peripheral support plate and the outer peripheral support plate is used as a shared air supply channel.

[0058] Combination Figures 4 to 7 As shown, this embodiment also provides a top-mounted air conditioner indoor unit, including: a casing 200, a heat exchange assembly 300, a fan assembly 400, and the three-dimensional air guide assembly 100 described in the above embodiment. The casing 200 has a downward-facing air supply cavity; the heat exchange assembly 300 and the fan assembly 400 are disposed within the casing 200; the three-dimensional air guide assembly 100 is assembled at the opening of the casing 200, and the air inlet 121 and air return outlet 101 of the three-dimensional air guide assembly 100 are respectively connected to the air supply cavity.

[0059] Combination Figure 5 , Figure 6 and Figure 7 As shown, the three-dimensional air guide assembly 100 and the roof-mounted air conditioner indoor unit provided in this embodiment also include a return air grille (not shown in the figure) and a filter 50, which are disposed at the aforementioned return air inlet.

[0060] The rooftop air conditioner indoor unit provided in the embodiment, by combining the above-mentioned three-dimensional air guide component 100 with the chassis of the existing rooftop air conditioner indoor unit, achieves flexible air supply while improving cooling or heating efficiency. The specific working modes can be found in the four modes (1), (2), (3), and (4) mentioned above.

[0061] As an example of a preferred control method, the details are as follows:

[0062] During heating, the second air guide plate assembly 30 closes the second air outlet 123, and the first air guide plate assembly 20 opens the first air outlet 122. Indoor air flows through the filter 50, the fan assembly 400, and the heat exchange assembly 300, then enters the three-dimensional air guide assembly 100 through the air inlet 121, and then blows out from the first air outlet 122 downwards or at a downward angle. This distinguishes it from the effect of side-discharged air during cooling. When blowing downwards, the hot air blows directly to the ground, providing a better feeling for people; blowing hot air at a small angle can expand the range of hot air diffusion.

[0063] During cooling, the second air guide plate assembly 30 opens the second air outlet 123, and the first air guide plate assembly 20 closes the first air outlet 122. Indoor air flows through the filter 50, the fan assembly 400, and the heat exchange assembly 300, then enters the three-dimensional air guide assembly 100 through the air inlet 121, and is finally blown out from the second air outlet 123. This air delivery method avoids some cold air being directly drawn back, reduces short-circuiting of the cold air flow field, and blows the air outwards, accelerating the cooling effect and saving energy.

[0064] The above embodiments are merely a full disclosure and not a limitation of this utility model. Any substitution of equivalent technical features based on the creative intent of this utility model without creative effort should be considered as within the scope of this application.
