Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] In order to achieve zero wind feeling air outlet in the current air conditioner indoor unit, the usual technical means is to open a hole in the air guide plate and make the air outlet closed. The air is discharged through the micro-holes on the air guide plate, reducing the direct blowing effect of the air outlet, thus achieving zero wind feeling air outlet.

[0003] The inventors' research revealed that existing zero-wind-sense airflow solutions, due to the air deflector typically closing the air outlet from bottom to top, result in a high flow at the top and a low flow at the bottom. This means that most of the airflow is close to the upper sidewall of the air outlet. Due to the wind-blocking effect of the air deflector, the airflow has a significant impact on the upper side of the air deflector, generating a large torque. The air guide door is subject to significant force and is prone to deformation over time. Furthermore, the air deflector is easily impacted by the airflow, preventing it from completely closing the air outlet. This creates a gap between the air deflector and the front panel, which easily forms condensation on the panel, impacting the user experience. Summary of the Invention

[0004] The problem solved by the present invention is how to prevent the air guide plate from being deformed and condensation from forming on the panel, thereby improving the user experience.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] In one aspect, the present invention provides an air conditioner, comprising a middle frame and a base, wherein the middle frame is arranged on the base, and a duct shell is also arranged on the base, an air outlet is arranged on the outside of the duct shell, and a first air guide plate is also rotatably arranged on the base, a first air guide hole is opened on the first air guide plate, and the first air guide plate is used to block the air outlet to achieve zero wind feeling air outlet, and a second air guide plate can also be rotatably arranged in the duct shell, a second air guide hole is opened on the second air guide plate, and the second air guide plate is used to be tilted in the duct shell when the first air guide plate blocks the air outlet, and the angle between the second air guide plate and the upper side wall of the duct shell is between 8°-20°, so that the air outlet can discharge air evenly.

[0007] The air conditioner provided by the present invention achieves zero-wind-feeling airflow by providing a first air guide hole on a first air guide plate, while the first air guide plate blocks the air outlet. Simultaneously, a second air guide plate is tiltedly arranged within the air duct housing, and a second air guide hole is provided on the second air guide plate. During actual airflow, the second air guide plate can partially block the airflow, preventing the airflow from directly impacting the upper side of the air guide plate. Furthermore, the second air guide hole is provided on the second air guide plate, and part of the airflow is obliquely blown out through the second air guide hole, thereby achieving a flow equalization effect and ensuring uniform airflow at the air outlet. Compared to the prior art, the present invention prevents the airflow from directly impacting the upper side of the air guide plate by tilting the second air guide plate with the second air guide hole, thereby preventing the air guide plate from deforming under stress, preventing the air guide plate from opening under stress, preventing a gap from forming between the air guide plate and the front panel, and preventing condensation from forming on the front panel, thereby improving the user experience. Furthermore, the flow equalization effect of the second air guide hole allows the air outlet to achieve uniform airflow, further ensuring the zero-wind-feeling requirement.

[0008] Furthermore, the angle between the second air guide plate and the upper side wall of the air duct shell is 15°.

[0009] The air conditioner provided by the present invention achieves better wind blocking and flow balancing effects by setting the second air guide plate to 15 degrees.

[0010] Furthermore, a distance L1 between an end of the second air guide plate close to the air outlet and the upper side wall of the air duct shell is smaller than a distance L2 between an end of the second air guide plate away from the air outlet and the upper side wall of the air duct shell.

[0011] In the air conditioner provided by the present invention, the end of the second air guide plate close to the air outlet is closer to the upper side wall of the air duct shell, so that a gradually decreasing air flow duct can be formed between the second air guide plate and the upper side wall of the air duct shell along the air outlet direction, squeezing the air flow and allowing part of the air flow to flow out along the second air guide hole, thereby achieving a better flow balancing effect.

[0012] Furthermore, a distance L1 between an end of the second air guide plate close to the air outlet and an upper side wall of the air duct shell is 5-15 mm.

[0013] In the air conditioner provided by the present invention, the distance between the second air guide plate and the upper side wall is set between 5-15 mm, wherein the distance can be determined by setting the width of the second air guide plate. If the second air guide plate is too wide, it will interfere with the first air guide plate, and if the second air guide plate is too narrow, it will affect the wind-shielding and flow-balancing effect. The present invention limits the appropriate distance so that the second air guide plate can have both structural dimensions and wind-shielding and flow-balancing effects, thereby avoiding interference with the first air guide plate.

[0014] Furthermore, a connecting plate is provided on the second air guide plate, a rotating shaft is provided on the connecting plate, and the rotating shaft is rotatably provided in the middle of the air duct shell for driving the second air guide plate to rotate.

[0015] The air conditioner provided by the present invention drives the connecting plate to rotate through the rotating shaft, and then drives the second air guide plate to rotate, thereby realizing angle adjustment of the second air guide plate, so that the second air guide plate can be adjusted to the optimal angle to better achieve the effect of wind blocking and uniform flow.

[0016] Furthermore, one end of the connecting plate is connected to the second air guide plate, and the other end of the connecting plate is also provided with a guide reinforcement plate, the guide reinforcement plate and the second air guide plate are spaced apart, and a guide channel is formed between the guide reinforcement plate and the second air guide plate, and the guide channel faces the air outlet.

[0017] The air conditioner provided by the present invention utilizes a flow guide reinforcement plate to divert airflow, redirecting it and ensuring better flow into the second air guide hole. Furthermore, a flow guide channel is formed between the second air guide plate and the flow guide reinforcement plate, allowing some air to flow toward the first air guide plate through the channel, ensuring zero draft from the first air guide plate. Furthermore, the flow guide reinforcement plate enhances the overall structural strength of the second air guide plate and the connecting plate, improving the rigidity of the overall structure.

[0018] Furthermore, the air guide reinforcement plate is parallel to the second air guide plate, and the width of the air guide reinforcement plate is smaller than the width of the second air guide plate.

[0019] The air conditioner provided by the present invention avoids the air flow disorder in the air duct shell caused by excessive wind blocking by the air guide reinforcement plate by arranging the air guide reinforcement plate to be parallel to the second air guide plate and the air guide reinforcement plate is narrower, thereby ensuring smooth outflow of the air flow.

[0020] Furthermore, the guide reinforcement plate is also provided with guide reinforcement ribs.

[0021] In the air conditioner provided by the present invention, the guide reinforcement plate is provided with guide reinforcement ribs, which can enhance the structural strength of the guide reinforcement plate and prevent the guide reinforcement plate from being deformed by stress.

[0022] Furthermore, a plurality of brackets are provided between the air guide reinforcement plate and the second air guide plate, and two ends of each bracket are respectively connected to the air guide reinforcement plate and the second air guide plate.

[0023] The air conditioner provided by the present invention has a large span between the air guide reinforcement plate and the second air guide plate. By adding a bracket between the two, the connection structure strength of the second air guide plate and the air guide reinforcement plate can be further enhanced, thereby improving the overall structural rigidity.

[0024] Furthermore, the guide reinforcement plate is arranged on the leeward side of the second guide plate.

[0025] The air conditioner provided by the present invention avoids the loss of air volume caused by the air guide reinforcement plate being arranged on the windward side and directly blocking the air flow by arranging the air guide reinforcement plate on the leeward side.

[0026] Furthermore, each of the second air guide holes passes through the second air guide plate, and the apertures at both ends of the second air guide hole are larger than the aperture in the middle of the second air guide hole.

[0027] The air conditioner provided by the present invention has a second air guide hole that penetrates the second air guide plate, and the second air guide hole presents an hourglass structure with large ends and a small middle, so that the air flow can better converge into the second air guide hole and flow out quickly, and at the same time, it can be easily demolded, which is convenient for the manufacture of the second air guide plate.

DETAILED DESCRIPTION

[0035] As disclosed in the background technology, the conventional method for achieving zero wind sensation is to directly use an air guide door with micro-holes to block the air outlet, and lean against the lower edge of the front panel, so that the airflow from the air outlet is forced to flow out from the micro-holes to achieve zero wind sensation or a breeze sensation, and avoid direct wind blowing. However, through wind duct simulation and actual experience, the air volume of conventional air outlets is small at the top and bottom, that is, the airflow is more concentrated on the upper side wall of the air duct for outlet, which will cause the upper part of the air guide door to be subjected to relatively large wind pressure. For an air guide door that closes from bottom to top, its rotating shaft is usually close to the lower edge of the air outlet, that is, its driving force point is usually close to the lower edge of the air outlet. The upper side of the air guide door is subjected to force, which will form a large torque, causing the rotating shaft to be subjected to a large torsional force, which will place higher requirements on the torsional resistance of the motor. Because the air guide door motor is typically small, it can easily reverse direction under prolonged stress, creating a gap between the air guide door and the front panel. This can lead to condensation on the front panel, which can then easily drip and affect the user experience. Furthermore, the air guide door can also deform under prolonged stress, similarly causing a gap between the door and the front panel. This deformation can also affect the product's appearance.

[0036] In order to solve the above problems, the present invention provides an air conditioner, which can prevent the air guide plate from deforming and prevent condensation from forming on the panel, thereby improving the user experience of the air conditioner. In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] First embodiment

[0038] See Figures 1 to 4 This embodiment provides an air conditioner 100, which can prevent the airflow from directly impacting the air guide structure in the zero wind feeling state, thereby avoiding the condensation problem caused by the gap, and can achieve uniform air flow, and the zero wind feeling effect is more uniform, thereby improving the user experience.

[0039] The present embodiment provides an air conditioner 100, including a middle frame 110 and a base 130. The middle frame 110 is set on the base 130, and the base 130 is further provided with an air duct shell 150. The outer side of the air duct shell 150 is provided with an air outlet 151. The base 130 is further rotatably provided with a first air guide plate 170, and the first air guide plate 170 is provided with a first air guide hole 171. The first air guide plate 170 is used to block the air outlet 151 to achieve zero wind feeling air outlet. A second air guide plate 180 is also rotatably provided in the air duct shell 150, and the second air guide plate 180 is provided with a second air guide hole 181. The second air guide plate 180 is used to be tilted in the air duct shell 150 when the first air guide plate 170 blocks the air outlet 151, and the angle between the second air guide plate 180 and the upper side wall of the air duct shell 150 is between 8° and 20°, so that the air outlet 151 can discharge air evenly.

[0040] In this embodiment, the air conditioner 100 is an indoor unit. The specific structures of the middle frame 110 and base 130 can be referenced from existing indoor units. The air duct housing 150 is disposed below the base 130 and is tilted downward to discharge air. The air duct housing 150 and the base 130 are integrally formed. The middle frame 110 is also provided with a front panel on the front side. The first air guide door engages with the front panel when it blocks the air outlet 151.

[0041] The air conditioner 100 provided in this embodiment realizes zero-wind-feeling air outlet by opening a first air guide hole 171 on the first air guide plate 170, and at the same time, the second air guide plate 180 is tiltedly arranged in the air duct shell 150, and the second air guide hole 181 is opened on the second air guide plate 180. When the air is actually outlet, the second air guide plate 180 can play a partial shielding role to prevent the airflow from directly impacting the upper side of the first air guide plate 170, and the second air guide hole 181 is opened on the second air guide plate 180, and part of the airflow is blown out obliquely through the second air guide hole 181, thereby realizing the effect of flow equalization and ensuring uniform air outlet 151. At the same time, because the airflow doesn't directly impact the upper side of the first air deflector 170, it prevents deformation and expansion of the first air deflector 170. This prevents the formation of gaps between the first air deflector 170 and the front panel, thus preventing condensation on the front panel and improving the user experience. Furthermore, the flow distribution through the second air guide holes 181 ensures uniform airflow from the air outlet 151, further ensuring a zero draft sensation.

[0042] It should be noted that the air conditioner 100 mentioned in this embodiment has a zero-wind-sense function. When the air conditioner 100 is in the zero-wind-sense state, the first air guide plate 170 blocks the air outlet 151 and closes the air outlet 151. The air outlet 151 achieves zero-wind-sense air discharge through the multiple first air guide holes 171 on the first air guide plate 170. The specific principle can be referred to the existing zero-wind-sense air conditioner. Of course, the air conditioner 100 in this embodiment also has other different air outlet modes such as sweeping air and direct blowing. This embodiment only uses the structure of the air conditioner 100 in the zero-wind-sense state as an example for explanation. When in other air outlet modes, the specific structure and position of the first air guide plate 170 and the second air guide plate 180 can be set or changed according to actual conditions and will not be described in detail here.

[0043] It should also be noted that in this embodiment, the second air guide plate 180 is disposed inside the air duct housing 150 and is tilted inside the air duct housing 150 when the first air guide plate 170 blocks the air outlet 151 to achieve zero-wind-feeling airflow. This ensures flow balancing and wind blocking within the air duct housing 150, slowing down the airflow from directly hitting the first air guide plate 170. Here, the upper sidewall of the air duct housing 150 has the same outlet direction as the airflow not in contact with the second air guide plate 180. A large amount of airflow is discharged along the upper sidewall of the air duct housing 150. The angle between the second air guide plate 180 and the upper sidewall of the air duct housing 150 refers to the angle between the windward surface of the second air guide plate 180 and the upper sidewall of the air duct housing 150. By limiting this angle to 8-20°, the inclination of the second air guide plate 180 is ensured to achieve the function of wind blocking and flow balancing.

[0044] In this embodiment, the angle between the second air guide plate 180 and the upper side wall of the air duct housing 150 is 15 degrees. By setting the second air guide plate 180 at 15 degrees, the wind blocking and flow distribution effects are better.

[0045] It is worth noting that in this embodiment, the first air guide plate 170 can be rotatably connected to the base 130 through the air guide frame 173, and driven by a motor to open or close the air outlet 151. Its specific driving principle and driving structure can refer to the existing air guide door structure.

[0046] In this embodiment, each second air guide hole 181 extends through the second air guide plate 180. The second air guide holes 181 are circular, with the diameters at both ends of the second air guide hole 181 being larger than the diameter in the middle of the second air guide hole 181. Specifically, the plurality of second air guide holes 181 are evenly distributed on the second air guide plate 180, each extending through the second air guide plate 180. The second air guide holes 181 form an hourglass structure with larger ends and a smaller center. This allows for better airflow converging into the second air guide holes 181 and faster outflow. This also facilitates demolding and facilitates manufacturing of the second air guide plate 180.

[0047] It should be noted that the first air guide hole 171 on the first air guide plate 170 may also adopt an hourglass structure with large ends and a small middle, so as to facilitate demoulding of the first air guide plate 170 .

[0048] In this embodiment, the distance L1 between the end of the second air guide plate 180 near the air outlet 151 and the upper sidewall of the air duct housing 150 is smaller than the distance L2 between the end of the second air guide plate 180 away from the air outlet 151 and the upper sidewall of the air duct housing 150. The end of the second air guide plate 180 near the air outlet 151 is closer to the upper sidewall of the air duct housing 150, allowing the second air guide plate 180 and the upper sidewall of the air duct housing 150 to form a gradually decreasing airflow channel along the air outlet direction, squeezing the airflow and causing part of the airflow to flow out through the second air guide holes 181, thereby achieving a better flow uniformity.

[0049] In this embodiment, the distance L1 between the end of the second air deflector 180 near the air outlet 151 and the upper sidewall of the air duct housing 150 is 5-15 mm. Specifically, the distance between the second air deflector 180 and the upper sidewall of the air duct housing 150 can be determined by setting the width of the second air deflector 180. If the second air deflector 180 is too wide, it will interfere with the first air deflector 170, while if the second air deflector 180 is too narrow, it will affect the wind blocking and flow balancing effect. In this embodiment, by setting the distance between the second air deflector 180 and the upper sidewall between 5-15 mm, the second air deflector 180 can achieve both structural size and wind blocking and flow balancing effect, while avoiding interference with the first air deflector 170.

[0050] Preferably, in this embodiment, the distance L1 between the outer end of the second air guide plate 180 and the upper side wall of the air duct shell 150 is 10 mm, that is, the minimum distance between the second air guide plate 180 and the upper side wall of the air duct shell 150 is 10 mm, and the distance between the inner end of the second air guide plate 180 and the upper side wall of the air duct shell 150 can be determined according to the width of the second air guide plate 180, so as not to interfere with the lower side wall of the air duct shell 150.

[0051] In this embodiment, a connecting plate 185 is provided on the second air guide plate 180, and a rotating shaft 183 is provided on the connecting plate 185. The rotating shaft 183 is rotatably disposed in the middle of the air duct housing 150 and is used to drive the second air guide plate 180 to rotate. The rotating shaft 183 drives the connecting plate 185 to rotate, and then drives the second air guide plate 180 to rotate, thereby achieving angle adjustment of the second air guide plate 180, so that the second air guide plate 180 can be adjusted to the optimal angle to better achieve the effect of wind blocking and uniform flow. Specifically, in this embodiment, the rotating shaft 183 can be driven by a stepper motor, so that the second air guide plate 180 can be adjusted to a suitable angle when the first air guide plate 170 is in a zero wind sense state. Alternatively, the angle between the second air guide plate 180 and the upper side wall of the air duct housing 150 can be adjusted between 8-20 degrees by using a stepper motor to achieve multiple gears and a variety of different zero wind sense air outlet effects.

[0052] Of course, in other preferred embodiments of the present invention, the rotating shaft 183 can also be fixedly set in the middle of the air duct shell 150, so that the position angle of the second air guide plate 180 is fixed, for example, it is fixed at an angle of 15° with the upper side wall of the air duct shell 150, so that no matter what mode the first air guide plate 170 is in, it can play the role of wind blocking and flow equalization, thereby achieving uniform air discharge from the air outlet 151.

[0053] It should be noted that in this embodiment, the second air deflector 180 is a straight plate structure, which can achieve a good wind-blocking and flow-distributing effect. Of course, the second air deflector 180 can also adopt a curved plate structure. The curvature and convex direction are not specifically limited here, as long as it can achieve the wind-blocking and flow-distributing effect.

[0054] In this embodiment, one end of the connecting plate 185 is connected to the second air guide plate 180, and the other end of the connecting plate 185 is further provided with a deflector reinforcement plate 190. The deflector reinforcement plate 190 is spaced apart from the second air guide plate 180, and a deflector channel is formed between the deflector reinforcement plate 190 and the second air guide plate 180, which faces the air outlet 151. The provision of the deflector reinforcement plate 190 serves to guide the air flow, redirecting it so that it flows more efficiently into the second air guide hole 181. Furthermore, the deflector channel formed between the second air guide plate 180 and the deflector reinforcement plate 190 allows some of the air to be discharged toward the first air guide plate 170 through the deflector channel, ensuring a zero-draft airflow outflow from the first air guide plate 170. Furthermore, the provision of the deflector reinforcement plate 190 enhances the overall structural strength of the second air guide plate 180 and the connecting plate 185, improving the rigidity of the overall structure.

[0055] It should be noted that the air guide reinforcement plate 190, the connecting plate 185 and the second air guide plate 180 are integrally formed here, and the distance between the air guide reinforcement plate 190 and the second air guide plate 180 should not be too large, so as to ensure that the second air guide plate 180 and the air guide reinforcement plate 190 can rotate freely in the air duct shell 150 without interfering with the upper and lower side walls of the air duct shell 150.

[0056] In this embodiment, the air guide reinforcement plate 190 is parallel to the second air guide plate 180, and the width of the air guide reinforcement plate 190 is smaller than the width of the second air guide plate 180. By arranging the air guide reinforcement plate 190 parallel to the second air guide plate 180 and making the air guide reinforcement plate 190 narrower, the air guide reinforcement plate 190 is prevented from excessively blocking the wind and causing turbulence in the air flow within the air duct housing 150, thereby ensuring smooth outflow of air.

[0057] It should be noted that in this embodiment, only the second air guide holes 181 are provided on the second air guide plate 180, while the air guide reinforcement plate 190 is a complete, unperforated structure, thereby serving to redirect the airflow. Furthermore, the air guide reinforcement plate 190, the rotating shaft 183, and the connecting plate 185 are all located on the leeward side of the second air guide plate 180. This allows the airflow between the second air guide plate 180 and the upper sidewall of the air duct housing 150 to first pass through the second air guide plate 180 before flowing through the guide channel or directly to the first air guide plate 170. This avoids the problem of airflow loss caused by the air guide reinforcement plate 190 being located on the windward side and directly blocking the airflow, as well as the problem of airflow loss caused by the rotating shaft 183 and the connecting plate 185 being located on the windward side and blocking the airflow.

[0058] See also Figure 5 In this embodiment, the guide reinforcement plate 190 is further provided with guide reinforcement ribs 191. Specifically, the guide reinforcement ribs 191 are provided on the guide reinforcement plate 190 near the connecting plate 185. On the one hand, providing the guide reinforcement ribs 191 on the guide reinforcement plate 190 can enhance the structural strength of the guide reinforcement plate 190 and prevent deformation thereof under stress. On the other hand, the strength of the connection structure between the guide reinforcement plate 190 and the connecting plate 185 can also be enhanced.

[0059] In this embodiment, a plurality of brackets 193 are further disposed between the air guide reinforcement plate 190 and the second air guide plate 180. Each bracket 193 has two ends connected to the air guide reinforcement plate 190 and the second air guide plate 180. Because the air guide reinforcement plate 190 and the second air guide plate 180 have a relatively large span, the addition of brackets 193 between them can further enhance the structural strength of the connection between the second air guide plate 180 and the air guide reinforcement plate 190, thereby improving the overall structural rigidity.

[0060] In this embodiment, two deflector reinforcement plates 190 are arranged along the same straight line. Three or four connecting plates 185 are provided on the second air deflector 180, with every two connecting plates 185 connected to a deflector reinforcement plate 190, thereby forming a deflector frame structure. Because a single deflector reinforcement plate 190 is relatively narrow and has low structural strength, the separate deflector reinforcement plates 190 prevent the span of each deflector reinforcement plate 190 from being too large, thereby increasing the overall structural strength of the resulting deflector frame structure.

[0061] The air conditioner 100 provided in this embodiment has the following working principle for achieving zero wind feeling: the air conditioner 100 is adjusted to the zero wind feeling mode, and the first air guide plate 170 is driven by the motor to cover the air outlet 151 to block the air outlet 151, and the upper edge of the first air guide plate 170 is engaged with the lower side of the front panel. At this time, the second air guide plate 180 is driven by the stepper motor to adjust the angle with the upper side wall of the air duct shell 150, and is adjusted between 8° and 20°. It is preferred to adjust the second air guide plate 180 to an angle of 15° with the upper side wall of the air duct shell 150, and the air starts to be discharged at this time. Airflow is transported from the internal wind wheel toward the air duct housing 150 and directly impacts the second air guide plate 180. Some of the airflow is blocked and flows out from both sides of the second air guide plate 180. Under the action of wind pressure, some of the airflow flows out through the second air guide holes 181 on the second air guide plate 180 and flows directly to the middle and lower portion of the first air guide plate 170, achieving uniform flow. At the same time, some of the airflow does not directly impact the second air guide plate 180, but instead flows directly to the first air guide plate 170 through the guide channel between the second air guide plate 180 and the air guide reinforcement plate 190. The second air guide plate 180 and the air guide reinforcement plate 190 achieve wind-blocking and uniform flow. The airflow that evenly impacts the first air guide plate 170 flows out through the first air guide holes 171, thereby slowing down the airflow speed and preventing direct airflow, achieving a zero-wind sensation effect.

[0062] The air conditioner 100 provided in this embodiment achieves uniform air outlet through the second air guide plate 180 and the guide reinforcement plate 190. Since the airflow does not directly impact the upper side of the first air guide plate 170, the first air guide plate 170 is prevented from being deformed by force, and the first air guide plate 170 is prevented from being forced to open, thereby preventing a gap from being formed between the first air guide plate 170 and the front panel, and preventing condensation from forming on the front panel, thereby improving the user experience.

[0063] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
