[0001] This application relates to the field of air guide plate technology, specifically to an air guide plate and an air conditioner. Background Technology

[0002] Air conditioners have air deflectors at their air outlets for directional airflow. However, in related technologies, switching the airflow direction using these deflectors requires complex mechanical structures, additional control circuitry, and sophisticated control algorithms. This results in complex motion structures, poor operational stability, and high costs. Utility Model Content

[0003] This application provides an air guide plate and an air conditioner, which can simplify the air guide structure, improve operational stability, and reduce the overall cost of the air conditioner.

[0004] On one hand, this application provides an air guide plate, comprising: a substrate layer; a moisture-absorbing deformable layer disposed on one side surface of the substrate layer, the moisture-absorbing deformable layer changing shape between a straight state and a bent state according to humidity changes; and a heat-sensitive deformable layer disposed on the substrate layer on the side surface away from the moisture-absorbing deformable layer, the heat-sensitive deformable layer changing shape between a straight state and a bent state according to temperature changes; when both the moisture-absorbing deformable layer and the heat-sensitive deformable layer are in a bent state, the bending directions of the moisture-absorbing deformable layer and the heat-sensitive deformable layer are the same.

[0005] In some embodiments, the moisture-absorbing deformable layer remains flat when its own humidity is lower than a first preset humidity, and bends and deforms when its own humidity is greater than or equal to the first preset humidity; the heat-deformable layer remains flat when its own temperature is lower than a first preset temperature, and bends and deforms when its own temperature is greater than or equal to the first preset temperature.

[0006] In some embodiments, the moisture-absorbing deformable layer bends and deforms when its own humidity is lower than a second preset humidity, and remains flat when its own humidity is greater than or equal to the second preset humidity; the heat-deformable layer bends and deforms when its own temperature is lower than a second preset temperature, and remains flat when its own temperature is greater than or equal to the second preset temperature.

[0007] In some embodiments, the air guide plate further includes a shape memory alloy layer disposed between the substrate layer and the moisture-absorbing deformation layer, wherein the moisture-absorbing deformation layer and the shape memory alloy layer have the same bending direction.

[0008] In some embodiments, the air guide plate further includes a shape memory alloy layer disposed between the substrate layer and the heat-deformable layer, wherein the heat-deformable layer and the shape memory alloy layer have the same bending direction.

[0009] In some embodiments, the shape memory alloy layer includes at least one shape memory alloy wire; when the shape memory alloy layer includes multiple shape memory alloy wires, the multiple shape memory alloy wires are spaced apart sequentially and arranged in the same layer.

[0010] On the other hand, embodiments of this application provide an air conditioner including the air guide plate described in any of the above embodiments.

[0011] In some embodiments, the air conditioner is provided with an air outlet, and the air guide plate is disposed at the air outlet and can be tilted and rotated to open or close the air outlet.

[0012] In some embodiments, when the air conditioner is in heating mode, the moisture-absorbing deformable layer and the heat-receiving deformable layer are bent downwards to make the air guide plate bend downwards, thereby causing the air guide plate to guide air downwards at an angle; when the air conditioner is in cooling mode, the moisture-absorbing deformable layer and the heat-receiving deformable layer remain straight to keep the air guide plate straight.

[0013] In some embodiments, when the air conditioner is in cooling mode, the moisture-absorbing deformable layer and the heat-receiving deformable layer are bent upwards to make the air guide plate bend upwards, thereby causing the air guide plate to guide air upwards at an angle; when the air conditioner is in heating mode, the moisture-absorbing deformable layer and the heat-receiving deformable layer remain straight to make the air guide plate remain straight.

[0014] This application embodiment, by setting a base layer, a moisture-absorbing deformation layer, and a heat-sensitive deformation layer, allows the moisture-absorbing deformation layer and the heat-sensitive deformation layer to change shape according to the temperature and humidity difference of the cold and warm air outlets in the air conditioner's cooling / heating modes. This allows the moisture-absorbing deformation layer and the heat-sensitive deformation layer to remain straight or bend, respectively, so that the air guide plate as a whole remains straight or bends towards a preset direction, thereby enabling the air guiding direction of the air guide plate to switch accordingly. Compared with related technologies, the air guide plate provided in this application embodiment does not require a complex air guiding mechanical structure, additional air guide plate control circuits, and relatively complex air guide plate control algorithms, which can simplify the air guiding structure, improve operational stability, and reduce the overall cost of the air conditioner.

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0029] like Figure 1 and Figure 2 As shown, in one aspect, this application provides an air guide plate 1, which includes a base layer 10, a moisture-absorbing deformation layer 20 and a heat-deformable layer 30, which can simplify the air guide structure, improve operational stability and reduce the overall cost of the air conditioner.

[0030] The substrate layer 10 serves as the main layer of the air guide plate 1, and can support the moisture-absorbing deformable layer 20 and the heat-deformable layer 30. The material of the substrate layer 10 can be determined according to actual needs, and can be a material with elastic deformation properties, such as metal or plastic. This application embodiment does not limit this.

[0031] A moisture-absorbing deformable layer 20 is disposed on one side surface of the substrate layer 10 and can change shape between a flat state and a curved state according to changes in humidity. The moisture-absorbing deformable layer 20 can absorb moisture from the surrounding air and change shape after absorbing moisture, so that the moisture-absorbing deformable layer 20 remains flat or is bent and deformed along a preset direction. The material of the moisture-absorbing deformable layer 20 can be determined according to actual needs, and moisture-absorbing deformable materials such as shape memory polymers that are sensitive to humidity can be used. This application embodiment does not limit this.

[0032] The heat-deformable layer 30 is disposed on the surface of the substrate layer 10 away from the moisture-absorbing deformable layer 20, and can change shape between a straight state and a bent state according to temperature changes. Accordingly, the moisture-absorbing deformable layer 20 and the heat-deformable layer 30 are located on opposite side surfaces of the substrate layer 10. The heat-deformable layer 30 can respond to changes in the ambient air temperature and undergo corresponding volume expansion and contraction and shape changes after absorbing or releasing heat, so that the heat-deformable layer 30 remains straight or bends and deforms along a preset direction. The material of the heat-deformable layer 30 can be determined according to actual needs, and can be heat-deformable materials such as temperature-sensitive shape memory polymers and carbon-based materials, etc., which are not limited in this embodiment. When both the moisture-absorbing deformable layer 20 and the heat-deformable layer 30 are in a bent state, the bending directions of the moisture-absorbing deformable layer 20 and the heat-deformable layer 30 are the same, so that the air guide plate 1 bends in the same bending direction to ensure the structural stability and consistency of the air guide plate 1.

[0033] like Figures 1 to 5As shown, when the air guide plate 1 provided in this embodiment is applied to an air conditioner, the moisture-absorbing deformation layer 20 and the heat-receiving deformation layer 30 can change shape according to the temperature and humidity difference between the cold and warm air outlets in the air conditioner's cooling / heating modes. This allows the moisture-absorbing deformation layer 20 and the heat-receiving deformation layer 30 to remain straight or bend, respectively, so that the air guide plate 1 as a whole remains straight or bends towards a preset direction. In this way, the air guide plate 1 can guide the cold and warm air in different directions according to their different properties, allowing the cold air to be discharged horizontally or tilted upwards to avoid direct cold air blowing on the human body and causing discomfort, while allowing the warm air to be discharged tilted downwards or horizontally to deliver the warm air to the area where the human body is located as quickly as possible or to increase the delivery distance of the warm air. Compared with related technologies, the air guide plate 1 provided in this embodiment has the ability to self-deform according to changes in temperature and humidity and switch the air guiding direction accordingly. It does not require a complex air guiding mechanical structure, additional air guide plate 1 control circuit, or a relatively complex air guide plate 1 control algorithm, which can simplify the air guiding structure, improve operational stability, and reduce the overall cost of the air conditioner.

[0034] The deformation characteristics of the moisture-absorbing deformable layer 20 in response to humidity and the deformation characteristics of the heat-deformable layer 30 in response to temperature can be determined according to actual needs, and this application embodiment does not limit them. In some embodiments, the moisture-absorbing deformable layer 20 can remain flat when its own humidity is lower than a first preset humidity, and bend and deform when its own humidity is greater than or equal to the first preset humidity; in other words, the moisture-absorbing deformable layer 20 gradually bends and deforms as the humidity increases, and gradually returns to flatness as the humidity decreases. The heat-deformable layer 30 can remain flat when its own temperature is lower than a first preset temperature, and bend and deform when its own temperature is greater than or equal to the first preset temperature; in other words, the heat-deformable layer 30 gradually bends and deforms as the temperature increases, and gradually returns to flatness as the temperature decreases. Thus, when the air conditioner is in heating mode and blowing warm air, the warm air causes the moisture-absorbing deformation layer 20 and the heat-sensitive deformation layer 30 to bend and deform respectively, so that the air guide plate 1 is bent as a whole; while when the air conditioner is in cooling mode and blowing cold air, the moisture-absorbing deformation layer 20 and the heat-sensitive deformation layer 30 remain straight, so that the air guide plate 1 is straight as a whole.

[0035] In other embodiments, the moisture-absorbing deformable layer 20 can bend and deform when its own humidity is lower than a second preset humidity, and remain flat when its own humidity is greater than or equal to the second preset humidity; in other words, the moisture-absorbing deformable layer 20 gradually bends and deforms as the humidity decreases, and gradually returns to flatness as the humidity increases. The heat-deformable layer 30 can bend and deform when its own temperature is lower than a second preset temperature, and remain flat when its own temperature is greater than or equal to the second preset temperature; in other words, the heat-deformable layer 30 gradually bends and deforms as the temperature decreases, and gradually returns to flatness as the temperature increases. Thus, when the air conditioner is in cooling mode and blowing cold air, the cold air causes the moisture-absorbing deformable layer 20 and the heat-deformable layer 30 to bend and deform respectively, making the air guide plate 1 as a whole curved shape; while when the air conditioner is in heating mode and blowing warm air, the moisture-absorbing deformable layer 20 and the heat-deformable layer 30 remain flat, making the air guide plate 1 as a whole flat shape.

[0036] like Figure 6 As shown, in some embodiments, the air guide plate 1 may include a first shape memory alloy layer 40, which is disposed between the substrate layer 10 and the moisture-absorbing deformable layer 20. The first shape memory alloy layer 40 expands and bends when heated. The moisture-absorbing deformable layer 20 and the first shape memory alloy layer 40 bend in the same direction, further enhancing the deformability of the air guide plate 1. In some examples, the first shape memory alloy layer 40 includes at least one shape memory alloy wire; when the first shape memory alloy layer 40 includes multiple shape memory alloy wires, the multiple shape memory alloy wires are spaced apart sequentially and arranged in the same layer.

[0037] In some embodiments, the air guide plate 1 may include a second shape memory alloy layer 50, which is disposed between the substrate layer 10 and the heat-deformable layer 30. The second shape memory alloy layer 50 expands and bends when heated, and the heat-deformable layer 30 and the second shape memory alloy layer 50 bend in the same direction, further enhancing the deformability of the air guide plate 1. In some examples, the second shape memory alloy layer 50 includes at least one shape memory alloy wire; when the second shape memory alloy layer 50 includes multiple shape memory alloy wires, the multiple shape memory alloy wires are spaced apart sequentially and disposed in the same layer.

[0038] In some embodiments, the air guide plate 1 may include an ear 60 for mounting the air guide plate 1 on an air conditioner.

[0039] like Figures 1 to 6As shown, on the other hand, this application embodiment provides an air conditioner that includes the air guide plate 1 of any of the above embodiments. The type of air conditioner can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, etc., and this application embodiment does not limit this. The air conditioner having the above-mentioned air guide plate 1 can simplify the air guiding structure, improve operational stability, and reduce the overall cost of the air conditioner.

[0040] In some embodiments, the air conditioner may be provided with an air outlet. The air guide plate 1 may be disposed at the air outlet and may be tilted and rotated to open or close the air outlet.

[0041] like Figure 4 As shown, in some examples, when the air conditioner is in cooling mode, the moisture-absorbing deformable layer 20 and the heat-sensitive deformable layer 30 can be bent upwards respectively, so that the air guide plate 1 bends upwards, thereby causing the air guide plate 1 to tilt upwards and guide the airflow, so that the cold air is discharged tilted upwards, avoiding the cold air blowing directly on the human body and causing discomfort; for example Figure 3 As shown, when the air conditioner is in heating mode, the moisture-absorbing deformable layer 20 and the heat-receiving deformable layer 30 remain straight to keep the air guide plate 1 straight, allowing the warm air to be discharged horizontally and increasing the air delivery distance. Here, the moisture-absorbing deformable layer 20 gradually bends and deforms as the humidity decreases, and gradually returns to a straight position as the humidity increases; the heat-receiving deformable layer 30 gradually bends and deforms as the temperature decreases, and gradually returns to a straight position as the temperature increases.

[0042] like Figure 5 As shown, in other examples, when the air conditioner is in heating mode, the moisture-absorbing deformable layer 20 and the heat-receiving deformable layer 30 can be bent downwards respectively, so that the air guide plate 1 bends downwards, thereby causing the air guide plate 1 to guide the air downwards at an angle, so that the warm air is delivered to the area where the human body is located as quickly as possible at an angle downwards, improving heating comfort; such as Figure 3 As shown, when the air conditioner is in cooling mode, the moisture-absorbing deformable layer 20 and the heat-sensitive deformable layer 30 remain straight to keep the air guide plate 1 straight, allowing the cold air to be discharged horizontally and preventing the cold air from blowing directly on the human body and causing discomfort. Here, the moisture-absorbing deformable layer 20 can gradually bend and deform as the humidity increases, and gradually return to a straight position as the humidity decreases; the heat-sensitive deformable layer 30 gradually bends and deforms as the temperature increases, and gradually returns to a straight position as the temperature decreases.

[0043] The air guide plate and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
