Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly to a dew prevention structure, an air deflector structure and an indoor air conditioner. Background Art

[0002] In the hot summer, air conditioners have become one of the essential household appliances in modern families. Installing an air deflector at the air outlet of the air conditioner can effectively adjust the air outlet direction, achieve the effect of directional air supply, and also increase the air supply range. Currently, the indoor units of wall-mounted air conditioners usually use double or single air deflectors, and basically all the air deflectors are long strips with a certain curvature. Taking wall-mounted air conditioners as an example, while the air conditioner brings a comfortable environment to users, it will also bring certain troubles to users.

[0003] When the air conditioner is in the cooling condition, cold air flows over the air guiding surface of the air deflector (the side of the air deflector facing the air outlet). The low-temperature air outlet gas can quickly cool the air deflector, resulting in the temperature on the side of the air deflector facing away from the air outlet being lower than the dew point temperature of the ambient temperature, and the temperature difference between it and the surrounding ambient temperature is relatively large. Therefore, dew condensation is more likely to occur on the side of the air deflector facing away from the air outlet. The accumulated dew condensation will form water droplets, and the water droplets falling indoors will reduce the user experience.

[0004] Common existing methods to solve the problem of dew condensation on the air deflector: The first is to make the air deflector in the middle of the air outlet when it is opened. However, this treatment method can only be applied to air deflectors with a relatively small surface curvature, and this method will reduce the rotation angle of the air deflector, affecting the air volume and having a poor dew prevention effect. The second is to perform special treatment on the material of the air deflector, such as adding flocked cloth on the surface of the air deflector, filling thermal insulation materials inside the air deflector, spraying hydrophobic films on the surface of the air deflector, etc. However, these methods can only delay the condensation phenomenon to a certain extent, cannot avoid the formation of condensed water, and have a poor dew prevention effect.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] Embodiment 1

[0038] Refer to Figures 1-4 as shown, wherein, Figure 2 and Figure 3The direction of the arrow in the figure indicates the direction of air flow, i.e., the direction of air outlet; the present embodiment provides an anti-condensation structure, including a drainage device 2, wherein the drainage device 2 is arranged at the air outlet end of the air guide plate 1, and the drainage device 2 cooperates with the air guide plate 1 to form a drainage air duct 100 that can guide part of the wind to pass through the inside thereof and blow toward the side of the air guide plate 1 away from the air outlet 6 and / or the bottom shell 7 of the air conditioner.

[0039] The air guide plate 1 is usually arranged at the air outlet 6 of the air conditioner. When used in a wall-mounted air conditioner, it is usually rotatably arranged at the air outlet of the air conditioner, and is usually in the shape of an arc-shaped long plate. The wind flowing out of the air outlet 6 flows along the surface of the air guide plate 1 toward the air outlet 6, playing a role in guiding the wind direction. Usually, along the wind outlet direction, one end of the air guide plate 1 used to be connected to the air conditioner housing is the connection end, and the other free end is the wind outlet end. After the airflow passes through the wind outlet end of the air guide plate 1, it flows away from the air guide plate 1 and is discharged into the room.

[0040] The anti-condensation structure of this embodiment is provided with a guide device 2 at the air outlet end of the air guide plate 1. The guide device 2 cooperates with the air guide plate 1 to form a guide air duct 100 which can guide the cold air to pass through the inside thereof and blow to the side of the air guide plate 1 away from the air outlet 6 and the bottom shell 7 of the air conditioner. Figure 3 As shown, part of the wind flowing along the side of the air guide plate 1 toward the air outlet 6 enters the drainage duct 100, and after flowing out through the drainage duct 100, it blows away the hot air near the above-mentioned position. At the same time, a layer of "cold air wall" is formed in the drainage duct 100 to prevent the hot air from adhering to the side of the air guide plate 1 away from the air outlet 6 and the bottom shell 7 of the air conditioner to form condensation, and the anti-condensation effect is good.

[0041] As an alternative embodiment, see Figure 2 and Figure 3 As shown, at least part of the air guiding device 2 is covered outside the air outlet end of the air guiding plate 1 , and the air guiding duct 100 is formed between the inner wall of the air guiding device 2 and the surface of the air guiding plate 1 .

[0042] The air guide plate 1 in this embodiment is an arc-shaped plate that is convex as a whole in the direction away from the air outlet 6. In the prior art, the side of the air guide plate 1 facing the air outlet 6 is a guide surface for guiding air. In this embodiment, when at least part of the guide device 2 is covered outside the air outlet end of the air guide plate 1, the inner wall of the guide device 2 and the concave surface of the air outlet end of the air guide plate 1 (that is, the side of the air guide plate 1 facing the air outlet 6, that is, Figure 2 and Figure 3 The upper surface of the middle air guide plate 1) and the convex surface of the air outlet end of the air guide plate 1 (i.e. the side of the air guide plate 1 facing away from the air outlet 6, i.e. Figure 2 and Figure 3 A guide air duct 100 is formed between the lower surface of the middle air guide plate 1. Figure 2 and Figure 3As shown, the air discharged from the air outlet 6 is diverted by the concave surface of the air deflector 1. A part of the air enters the diversion air duct 100 and flows therein. After reaching the edge position of the air outlet end of the air deflector 1, the air changes direction. Under the guiding of the inner wall of the diversion device 2 and the convex surface of the air outlet end of the air deflector 1, the air blows towards the convex surface part of the air deflector 1 outside the diversion device 2 and the position of the air conditioner bottom shell 7, dispersing the nearby hot air. Another part of the air continues to flow and diffuse away from the air deflector 1 along the concave surface of the air deflector 1 and the outer surface of the diversion device 2 in sequence.

[0043] Considering that the boundary layer separation phenomenon occurs when the air flow passes through the concave surface of the air outlet end of the air deflector 1, in order to enable the diversion device 2 to achieve the diversion effect while preventing the deterioration of noise; as an optional implementation manner, at the air outlet end part of the air deflector, the diversion device covers 1 / 8 - 1 / 2 part of the side of the air deflector facing the air outlet and covers 1 / 8 - 1 / 2 part of the side of the air deflector facing away from the air outlet; the part of the diversion device 2 covering the air deflector 1 within the above range can achieve a good diversion effect while preventing the deterioration of noise. Preferably, referring to Figure 2 and Figure 3 As shown, at the air outlet end part of the air deflector 1, when the diversion device 2 covers 1 / 4 part of the side of the air deflector 1 facing the air outlet 6 and covers 1 / 4 part of the side of the air deflector 1 facing away from the air outlet 6, the diversion effect and the effect of preventing noise deterioration are better.

[0044] In the air outlet direction, when the diversion device 2 covers the air deflector 1 with too large a distance, the diversion effect may not be achieved, and the air flow directly flows out through the concave surface of the air deflector 1 and the upper surface of the diversion device 2; when the covering area of the diversion device 2 at the air outlet end of the air deflector 1 is too small, the air flow detaches from the concave surface of the air deflector 1 and impacts with the diversion device 2, which will deteriorate the noise and affect the user experience. Therefore, through theoretical analysis, at the air outlet end of the air deflector 1, when the part of the diversion device 2 covering the concave surface of the air deflector 1 accounts for 1 / 4 of the entire concave surface and the part covering the convex surface of the air deflector 1 accounts for 1 / 4 of the entire convex surface, the air flow will flow along the surface of the air deflector 1, which can achieve the diversion effect while reducing the impact and reducing the noise deterioration.

[0045] In order to reduce the influence of the above diversion device 2 on the air supply effect and take into account the air supply distance of the air deflector 1; as an optional implementation manner, referring to Figure 3 As shown, the inner diameter of the diversion air duct 100 shows a decreasing trend from its air inlet to its air outlet. In other words, the distance between the inner wall of the diversion device 2 and the surface of the air deflector 1 shows a decreasing trend along the air flow direction in the diversion air duct 100; preferably, the inner diameter of the diversion air duct 100 gradually decreases from its air inlet to its air outlet.

[0046] The shape of the above diversion air duct 100 forms a gradually shrinking and accelerating flow channel. The cold air increases in speed after passing through the diversion air duct 100 in the diversion device 2, and the blowing distance is farther. At the same time, it can better cool the area below the air conditioner.

[0047] This embodiment provides a specific implementation of the drainage device 2. Figures 1-3 As shown, the air guiding device 2 includes a cover body 21 , which is disposed on the air outlet end of the air guide plate 1 and is gap-matched with the surface of the air guide plate 1 to form an air guiding duct 100 .

[0048] Preferably, see Figure 1 The cover 21 covers the entire outlet end of the air guide plate 1 in a direction perpendicular to the air outlet direction, that is, the cover 21 covers the entire outlet end of the air guide plate 1 in the length direction of the air guide plate 1. The shape of the cover 21 is adapted to the shape of the outlet end of the air guide plate 1. Preferably, the corresponding position of the cover 21 and the end edge of the outlet end of the air guide plate 1 is in an arc shape to ensure smooth reversal of the airflow.

[0049] As an optional implementation, combining Figures 1-3 As shown, the cover body 21 has an open portion 211 (as shown in FIG. Figure 1 ), the open portion 211 of the cover body 21 (such as Figure 1 ) forms an air inlet of the drainage duct 100 with the side of the air guide plate 1 facing the air outlet 6 (the concave side of the air guide plate 1), and forms an air outlet 6 of the drainage duct 100 with the side of the air guide plate 1 facing away from the air outlet 6 (the convex side of the air guide plate 1).

[0050] The above-mentioned cover body 21 only includes the above-mentioned open part 211, which makes it convenient for the air flow to enter the guide air duct 100 from the air inlet after being guided by the concave surface of the air guide plate 1, and then flow out through the air outlet 6 and blow to the part of the convex surface of the air guide plate 1 located outside the cover body 21 and the air conditioner bottom shell 7, thereby reducing the accumulation of hot air near the above-mentioned position and preventing the formation of condensation.

[0051] As an optional implementation, the flow guide device 2 in this embodiment is rotatable, and a closed air duct state is formed between the flow guide device 2 and the air guide plate 1, where the flow guide device 2 and the concave surface of the air guide plate 1 are in close contact with each other. Figure 2 ; and the air duct opening state where the concave gap between the air guide plate 1 and the air guide device 2 cooperates, such as Figure 3 .

[0052] The drainage device 2 is rotatably arranged at the air outlet end of the air guide plate 1 to realize the above-mentioned air duct closed state and air duct open state. When condensation is difficult to form on the convex surface of the air guide plate 1 and the bottom shell 7 of the air conditioner, the drainage device 2 is rotated until the drainage device 2 and the concave surface of the air guide plate 1 are tightly attached to close the drainage air duct 100, and the air flow no longer enters the drainage air duct 100, preventing the drainage device 2 from being still open to affect the air supply capacity.

[0053] As an alternative embodiment, see Figure 2 and Figure 3, the drainage device 2 further includes a shaft 22 which is rotatably arranged on the air guide plate 1 to drive the entire drainage device 2 to rotate to form a closed air duct state and an open air duct state. The shaft 22 is arranged at the air outlet end of the air guide plate 1, and the cover body 21 is also connected to the air outlet end of the air guide plate 1 through the shaft 22; when the shaft 22 rotates, the cover body 21 rotates around the shaft 22 within a certain range. The shaft 22 can rotate itself by being connected to a driving device. The driving method for the driving device to drive the shaft 22 to rotate is a conventional setting in the art and is not shown here. For example, commonly, the shaft 22 can be driven by a motor, and the shaft 22 can be connected to the output shaft of the motor through a connecting rod to facilitate setting the motor outside the drainage device 2 without occupying the internal space of the drainage device. Details are not described here, and those skilled in the art can select the driving method according to the actual situation.

[0054] As an optional embodiment, the drainage device 2 further includes: the above-mentioned driving device which is drivingly connected to the shaft 22 and drives the shaft 22 to rotate (such as the motor drives the shaft 22 to rotate through a connecting rod); a temperature detection device 4 which is located inside the air guide plate 1 and is used to detect the temperature of the side of the air guide plate 1 facing away from the air outlet 6; a controller 5 which is located inside the air guide plate 1 and is connected to the driving device and the temperature detection device 4, and is used to receive the temperature signal of the temperature detection device 4 and control the operation of the driving device according to the received temperature signal.

[0055] The above temperature detection device 4 can adopt an existing temperature sensor, and the controller 5 can adopt a single-chip microcomputer, etc. Refer to Figure 2 and Figure 3 , the temperature sensor is wire-connected to the controller 5 and is fixed inside the air guide plate 1 in an embedded manner and is located at the middle position of the air guide plate 1 to facilitate detecting the temperature of the surface of the air guide plate 1. Preferably, the temperature detection device 4 includes a first temperature sensor for detecting the temperature of the convex surface of the air guide plate 1 and a second temperature sensor for detecting the temperature of the convex surface of the air guide plate 1 and the environment temperature of the air conditioner bottom shell 7. The first temperature sensor and the second temperature sensor are both connected to the controller 5.

[0056] It should be noted that the number of the above temperature detection devices 4 can be one or more to facilitate detecting the temperatures at multiple places on or near the convex surface of the air guide plate 1. The controller 5 can receive the data output by the temperature detection device 4, and compare the temperature data output by the temperature detection device 4 with the dew point temperature of the environment. And it can control the rotation of the shaft 22 of the drainage device 2 (control the rotation of the shaft 22 by controlling the operating state of the driving device) to realize the on-off state of the drainage air duct 100.

[0057] In an embodiment of the present invention, when the refrigeration mode is turned on, the cold air blown out by the wall-mounted air conditioner indoor unit is directionally sent through the air deflector 1. The temperature detection device 4 also starts to work simultaneously to detect the temperature of the back surface of the air deflector 1 and the air nearby. The controller 5 receives the temperature data detected by the temperature detection device 4, compares the detected temperature data with the dew point temperature of the environment. Once it is found that the temperature of the surface of the air deflector 1 is close to the dew point temperature of the environment while the temperature of the air near the air deflector 1 is higher than the dew point temperature, the controller 5 will rotate the shaft 22 (the controller 5 controls the operation of the driving device, such as controlling the rotation of the motor), so that the drainage device 2 is in the air duct opening state. When in the air duct opening state, the cold air can pass through the tapered acceleration type drainage air duct 100 inside the drainage device 2 and directly blow the convex surface of the air deflector 1 and the air conditioner bottom case 7, which can quickly disperse the hot air agglomerated near the convex surface of the air deflector 1 and the air conditioner bottom case 7, and at the same time form a "cold air wall" to isolate the hot air and prevent the occurrence of condensation phenomenon.

[0058] Embodiment 2

[0059] This embodiment is an improvement based on the above embodiment. Refer to Figures 1-3 As shown, the drainage device 2 further includes a flow disturbing part 3. The flow disturbing part 3 is located at the part of the drainage device 2 facing away from the air deflector 1 and forms a flow disturbing gap 200 allowing air flow to pass between the flow disturbing part 3 and this part, so as to disturb the air flow passing through the surface of the drainage device 2. Specifically, the above-mentioned flow disturbing part 3 is fixedly connected to the cover body 21 through a connecting rod 31, and a flow disturbing gap 200 allowing air flow to pass is formed between the part of the cover body 21 corresponding to the edge of the air outlet end of the air deflector 1 and the flow disturbing part 3.

[0060] The above-mentioned flow disturbing part 3 is in clearance fit with the drainage device 2. Refer to Figure 3 As shown, a part of the air guided by the concave surface of the air deflector 1 enters the drainage air duct 100, and another part flows over the upper surface of the drainage device 2. After this part of the air flow reaches the flow disturbing part 3, a part of it flows through the above-mentioned flow disturbing gap 200, and there is still a part that flows around the surface of the flow disturbing part 3. Due to the setting of the flow disturbing part 3, the disturbance of the air around the air deflector 1 and the heat transfer rate are strengthened, and it also plays a part of the drainage role, reducing the generation of condensation on the air deflector 1, and can play a certain beneficial effect on keeping the surface of the air deflector 1 dry.

[0061] As an optional implementation manner, refer to Figures 1-3 As shown, the above-mentioned flow disturbing part 3 is a columnar structure extending along the length direction of the air deflector 1. The flow disturbing part 3 with the above structure can enable the air flow passing through the concave surface of the air deflector 1 and the surface of the drainage device 2 in the air outlet direction to be affected by the flow disturbing part 3, strengthening the disturbance effect of the air flow and the air heat transfer rate. Even when the drainage air duct 100 is in the air duct closed state, the flow disturbing part 3 can still enhance the heat exchange capacity of the air near the air deflector 1 and play a certain role in preventing the hot air from agglomerating on the back surface of the air deflector 1 and causing the condensation phenomenon.

[0062] Preferably, the length of the spoiler portion 3 is not less than the extension length of the air deflector 1.

[0063] Considering that the shape of the spoiler portion 3 should facilitate the outflow of the outgoing air flow, preferably, the cross-section of the spoiler portion 3 is circular or rhombic or elliptical.

[0064] Since the setting of the spoiler portion 3 has a spoiler effect while also having a certain resistance to the outgoing air flow, in order to balance the spoiler effect and reduce the resistance to the air flow, the air deflector 1 is arc-shaped. Preferably, the center of the cross-section of the above-mentioned spoiler portion 3 is located on the tangent line of the edge of the air outlet end of the corresponding air deflector 1.

[0065] The above setting position of the spoiler portion 3 can not only have a spoiler effect on the outgoing air flow flowing on the surface of the air deflector 1, strengthen the heat exchange with the surrounding air, but also reduce the interception resistance of the spoiler portion 3 to the outgoing air flow, preventing insufficient air supply distance.

[0066] Also considering both the spoiler effect of the spoiler portion 3 and reducing the resistance to the air flow, preferably, the above-mentioned spoiler portion 3 is cylindrical, the cross-sectional diameter of the spoiler portion 3 is between 6 mm and 12 mm, and the gap between the spoiler portion 3 and the air outlet end of the air deflector 1 is between 6 cm and 12 cm, which can optimize the spoiler effect while minimizing the resistance to the air flow as much as possible.

[0067] Embodiment 3

[0068] See Figures 1-4 As shown, this embodiment provides an air deflector structure, which is arranged at the air outlet 6 of the air conditioner. The air deflector structure includes the above-mentioned anti-condensation structure and the air deflector 1, and the anti-condensation structure is located on the air deflector 1. Due to the above-mentioned anti-condensation structure, the air deflector structure of this embodiment can prevent condensation from occurring on the side of the air deflector 1 facing away from the air outlet 6, and prevent the condensed water from dripping indoors and affecting the user experience.

[0069] In order to reduce the noise generated by the air flow impacting the air deflector 1 at the air outlet 6, as an optional implementation manner, see Figure 4 As shown, the number of air deflectors 1 at the air outlet 6 is one, and the size of the air deflector 1 can completely cover the air outlet 6. Only one air deflector 1 is arranged at the above-mentioned air outlet 6, which can prevent the relatively large noise generated by the air flow impacting multiple air deflectors 1 at the air outlet 6. One end of the air deflector 1 is rotatably connected to the air conditioner housing, and the rotation of the air deflector 1 can open and close the air outlet 6; among them, the rotation connection method of the air deflector 1 is a mature technology in the art, such as a connecting rod assembly can be used, etc., which will not be elaborated here.

[0070] Embodiment 4

[0071] This embodiment provides an air conditioner indoor unit, including the above-mentioned air deflector structure. An evaporator 9, a cross-flow fan blade 8, etc. are arranged inside the air conditioner housing. The air heated by the evaporator 9 is blown out from the air outlet 6 under the action of the cross-flow fan blade 8. The air deflector structure is located at the position of the air outlet 6, and the anti-condensation structure is used to prevent condensation from occurring on the side of the air deflector 1 facing away from the air outlet 6, so as to prevent the condensed water from dripping indoors and affecting the user experience. Refer to Figure 4 , and there is also an electric auxiliary heating device 10 in the indoor unit housing, which is convenient to change the heating amount according to the change of the room temperature and the size of the indoor unit air volume, and improve the heat exchange efficiency.

[0072] A wall-mounted air conditioner includes the above-mentioned air conditioner indoor unit.
