Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an air guide structure and an indoor air conditioner unit. Background Technology

[0002] Air conditioners have become an indispensable electrical appliance in our lives. Their basic function is to regulate the indoor environment by cooling or heating. In order to improve the user experience, the air supply performance of air conditioners, especially the air supply direction and the comfort of the airflow, has become an important direction for technological improvement.

[0003] Currently, most air conditioner indoor units on the market generally use a single air guide plate structure to adjust the air outlet direction. For example, Chinese patent "CN222783692U" discloses "an air guide plate assembly and an air conditioner having the same". This air conditioner opens or closes the air outlet by rotating the first end of the first air guide plate to one end of the housing in the width direction of the air outlet. This allows the first air guide plate to close the air outlet and guide the airflow from the air outlet to blow out at different angles, thus achieving different air supply states of the air conditioner. Although the single air guide plate structure can guide the airflow to different directions by changing its angle, due to the limited air guiding angle, in cooling mode, some cold air will still blow directly into the user's activity area without being fully guided, which can easily cause discomfort to the human body. Moreover, in heating mode, it is difficult to concentrate the hot air upward to promote indoor air circulation, affecting the overall heating efficiency of the room. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an air guiding structure and an indoor air conditioning unit, which solves the problem that existing indoor air conditioning units using a single air guiding plate structure cannot accurately guide air.

[0005] On the one hand, according to the embodiments of this utility model, the present utility model adopts the following technical solution:

[0006] An air guide structure, installed on an air conditioner housing, for opening and closing the air conditioner outlet, includes:

[0007] The first air guide plate and the second air guide plate are both equipped with a rotating shaft. Both rotating shafts are rotatably mounted on the air conditioner housing and located on opposite sides of the air conditioner outlet.

[0008] The driver is located in the air conditioner housing and is connected to two rotating shafts respectively. It is used to control the rotation of the first air guide plate and the second air guide plate to open and close the air conditioner outlet.

[0009] Preferably, the driver consists of two motors, both of which are located in the air conditioner housing, and the output shafts of the motors are connected to the corresponding rotating shafts.

[0010] Preferably, the end of the rotating shaft is provided with a slot, and the output shaft of the motor is provided with a retaining shaft, which is engaged with the slot.

[0011] Preferably, the first air guide plate and / or the second air guide plate have a plurality of air outlet holes that penetrate through them.

[0012] Preferably, the air outlets are evenly spaced.

[0013] Preferably, both the first and second air guide plates are made of plastic.

[0014] On the other hand, the present invention also adopts the following technical solution:

[0015] An indoor unit for an air conditioner includes an air guiding structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By independently controlling the coordinated rotation of the first and second air guide plates, an air guiding angle much larger than that of a single air guide plate can be formed. That is, during cooling, the first and second air guide plates can rotate together to an angle close to vertical downwards, completely guiding the cold airflow to the ground and allowing it to diffuse along the ground, completely eliminating the problem of cold air blowing directly on people. During heating, the first and second air guide plates can rotate together to an angle closer to the ceiling, completely guiding the hot airflow to the ceiling. Utilizing the principle of natural sinking of hot air, this promotes air circulation throughout the room, achieving rapid and uniform heating, avoiding the accumulation of hot air at the top of the room, and greatly improving the user's comfort experience.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] This utility model embodiment proposes an air guiding structure, installed on the air conditioner housing 1, for opening and closing the air conditioner outlet 101, including:

[0031] The first air guide plate 2 and the second air guide plate 3 are both provided with a rotating shaft 201. The two rotating shafts 201 are rotatably mounted on the air conditioner housing 1 and located on opposite sides of the air conditioner outlet 101.

[0032] The driver is located in the air conditioner housing 1 and is connected to two rotating shafts 201 respectively. It is used to control the rotation of the first air guide plate 2 and the second air guide plate 3 to open and close the air conditioner outlet 101.

[0033] In this embodiment, both the first air guide plate 2 and the second air guide plate 3 are rotatably mounted on the air conditioner housing 1 via their respective pivot shafts 201, such as... Figure 1 As shown, the first air guide plate 2 and the second air guide plate 3 are located on the upper and lower sides of the air conditioner outlet 101. Under the action of the driver, the first air guide plate 2 and the second air guide plate 3 can be controlled respectively. And by independently controlling the first air guide plate 2 and the second air guide plate 3 to rotate together, they can be combined to form an air guiding angle that is much larger than that of a single air guide plate structure.

[0034] During cooling, the first air guide plate 2 and the second air guide plate 3 can rotate together to a near-vertical downward angle under the action of the driver, such as... Figure 3 As shown, the cold airflow is completely directed to the ground, allowing it to diffuse along the ground, thus completely eliminating the problem of cold air blowing directly onto the human body.

[0035] During heating, the first air guide plate 2 and the second air guide plate 3 can rotate together under the action of the driver to an angle closer to the ceiling, such as... Figure 2As shown, the hot airflow is directed entirely to the ceiling, utilizing the principle of natural sinking of hot air to promote air circulation throughout the room, achieving rapid and uniform heating. This avoids hot air accumulating at the top of the room, greatly enhancing the user's comfort experience. The entire process, due to the more precise and concentrated airflow direction, reduces energy waste in ineffective spaces, thereby accelerating the room temperature adjustment and achieving energy-saving and efficiency-enhancing effects.

[0036] Specifically, the actuator can adopt an electric telescopic rod structure, connecting the telescopic end of the electric telescopic rod to the first air guide plate 2 and the second air guide plate 3. The movement of the first air guide plate 2 and the second air guide plate 3 is controlled by the telescopic rod's extension and retraction. To improve transmission efficiency, the actuator structure is optimized, such as... Figure 6 As shown, the driver consists of two motors 4, both of which are located on the air conditioner housing 1. The output shaft of each motor 4 is connected to the corresponding rotating shaft 201. The two motors 4 are driven independently, connecting to the first air guide plate 2 and the second air guide plate 3 respectively. Each motor 4 can precisely control the first air guide plate 2 or the second air guide plate 3 to stay at any angle, making the adjustment more stable.

[0037] Secondly, the rotating shaft 201 is fixedly connected to the output shaft of the motor 4. The fixed connection can be achieved through bonding or screw connection. Furthermore, for ease of assembly and disassembly, a slot 203 is provided at the end of the rotating shaft 201, and the output shaft of the motor 4 is provided with a retaining shaft 401, which engages with the slot 203. During assembly on the production line, simply align the retaining shaft 401 of the motor 4 with the slot 203 of the rotating shaft 201 and insert it axially to complete the power connection assembly, improving production efficiency. The engaging end of the slot 203 has a rectangular structure, and the slot 203 itself is a corresponding rectangular groove, ensuring strong engagement.

[0038] Specifically, such as Figure 5 As shown, the first air guide plate 2 and / or the second air guide plate 3 have a plurality of air outlet holes 202 penetrating through them. When the first air guide plate 2 or the second air guide plate 3 has a plurality of air outlet holes 202 penetrating through them, the first air guide plate 2 or the second air guide plate 3 is rotated to the specified position by the corresponding motor 4. Figure 4 As shown, several air outlets 202 disperse and cut the concentrated cold air stream into countless small, slow airflows, making the blown air very gentle and soothing, i.e., the gentle breeze mode. When the first air guide plate 2 and the second air guide plate 3 have several air outlets 202 penetrating through them, as... Figure 4 As shown, the position of the first air guide plate 2 remains unchanged, while the second air guide plate 3 is gradually raised, allowing more air outlets 202 to participate in the airflow, further improving the effect of gentle breeze.

[0039] Meanwhile, when the first air guide plate 2 or the second air guide plate 3 has several air outlet holes 202 that penetrate it, and it needs to close the air conditioner outlet 101, in order to prevent dust, the corresponding motor 4 controls the air guide plate structure with air outlet holes 202 to first fasten to the air conditioner outlet 101, and finally controls another air guide plate structure to close each air outlet hole 202. When the first air guide plate 2 and the second air guide plate 3 have several air outlet holes 202 that penetrate it, the air outlet holes 202 of the first air guide plate 2 and the air outlet holes 202 of the second air guide plate 3 are staggered. When the first air guide plate 2 and the second air guide plate 3 are closed at the air conditioner outlet 101, the air outlet holes 202 of the first air guide plate 2 are blocked by the second air guide plate 3, and the air outlet holes 202 of the second air guide plate 3 are blocked by the first air guide plate 2.

[0040] Moreover, the air outlets 202 are evenly spaced, and the uniform array of holes can stably and continuously disperse the concentrated airflow into countless uniform micro-airflows, avoiding airflow disturbance and fluctuation, and ensuring the stability and consistency of the soft wind output.

[0041] Specifically, such as Figures 1 to 5 As shown, both the first air guide plate 2 and the second air guide plate 3 are made of plastic, which can be produced by injection molding. This results in less waste and can significantly reduce the manufacturing cost of parts and the material cost of the whole machine. At the same time, the plastic material is lightweight, which reduces the load on the motor 4.

[0042] like Figure 1 As shown in the figure, this utility model embodiment also proposes an air conditioner indoor unit, including the above-mentioned air guide structure. The specific structure of the air guide structure is as described in the above embodiment. Since this air conditioner indoor unit adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
