Description

Technical Field

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

[0002] When the indoor unit of a wall-mounted air conditioner is cooling, the temperature at its air outlet is much lower than the indoor temperature. Due to this temperature difference, hot and cold air can easily mix at the lower edge of the air guide plate, where the cooling airflow is not easily reached. This causes condensation to form at the lower edge of the air guide plate. When the condensation droplets are large or the air guide plate moves again, the condensate will drip onto the ground, affecting the user experience. Utility Model Content

[0003] This application provides an air guide plate and an air conditioner to solve the problem of condensation easily generated by existing air guide plates.

[0004] In a first aspect, embodiments of this application provide an air guide plate, the air guide plate including an air guide plate body, the air guide plate body having a first edge and a second edge, the first edge and the second edge being disposed opposite to each other in the width direction of the air guide plate body; the air guide plate body having a cavity, the cavity being disposed in an hourglass shape along the direction from the first edge to the second edge, and a movable medium that can move under the action of gravity being disposed inside the cavity.

[0005] Optionally, the cavity includes a first cavity, a second cavity, and a channel. The first cavity, the channel, and the second cavity are arranged sequentially along the direction from the first edge to the second edge and form an hourglass-shaped structure. The channel connects the first cavity and the second cavity, and the width L1 of the channel is 0.25mm to 0.35mm.

[0006] Optionally, the air guide plate body is a transparent structure.

[0007] Optionally, the air guide plate body includes an inner surface and an outer surface arranged opposite to each other along its own thickness direction, and the cavity includes a first side surface arranged close to the outer surface, wherein the average distance L2 between the first side surface and the outer surface is 1mm to 1.5mm.

[0008] Optionally, the air guide plate further includes a rotating arm, one end of which is rotatably connected to the air guide plate body, and the other end of which is rotatably connected to the air conditioner casing.

[0009] Optionally, the air guide plate body is provided with a connecting part, the connecting part is located near the first edge, and the air guide plate body is connected to one end of the rotating arm through the connecting part.

[0010] Optionally, the air guide plate body has a driving part and a rotating part at both ends along its length. The rotating part is used to rotately connect with the housing of the air conditioner, and the driving part is used to connect with a driving component, which can drive the air guide plate body to rotate.

[0011] Secondly, this application also provides an air conditioner, which includes a housing and the aforementioned air guide plate. The housing has an air outlet, and the air guide plate is rotatably disposed at the air outlet.

[0012] Optionally, the air conditioner further includes a drive unit, which is disposed on the housing and can drive the air guide plate to rotate.

[0013] Optionally, the air guide plate has a lower air guide position and a closed position during rotation. The air conditioner is configured such that: when the air conditioner is in cooling mode, the air guide plate is in the lower air guide position so that the airflow is sent downward, and the position of the second edge of the air guide plate body is lower than the position of the first edge of the air guide plate body; when the air conditioner is in the off state, the air guide plate is in the closed position, and the position of the second edge of the air guide plate body is higher than the position of the first edge of the air guide plate body.

[0014] The air guide plate and air conditioner provided in this application embodiment have a cavity set on the air guide plate body. The cavity is hourglass-shaped along the direction from the first edge to the second edge of the air guide plate body, and a movable medium that can move under the action of gravity is provided in the cavity. So when the air conditioner is cooling, the free movement of the movable medium causes the air guide plate body to become unbalanced, so that the air guide plate body automatically adjusts the air guiding angle under the influence of gravity, thereby changing the space for the mixing of hot and cold air, avoiding condensation at the lower edge of the air guide plate body, and thus improving the user experience.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0035] This application provides an air guide plate 100, which can be installed at the air outlet 201 of the air conditioner housing 200 to change or guide the direction of the airflow from the air conditioner, thereby improving the comfort and efficiency of indoor temperature regulation.

[0036] like Figures 1-6As shown, the air guide plate 100 provided in this embodiment includes an air guide plate body 110, which has a first edge 111 and a second edge 112. The first edge 111 and the second edge 112 are disposed opposite to each other in the width direction of the air guide plate body 110. The air guide plate body 110 is provided with a cavity 120, which is hourglass-shaped along the direction from the first edge 111 to the second edge 112 of the air guide plate body 110. A movable medium 130 that can move under the action of gravity is provided inside the cavity 120. The movable medium 130 can be solid particles (e.g., sand) or liquid.

[0037] Specifically, the air guide plate body 110 includes an inner surface 113 and an outer surface 114, which are arranged opposite to each other along the thickness direction of the air guide plate body 110. The inner surface 113 of the air guide plate body 110 refers to the side of the air guide plate body 110 facing the inside of the air conditioner housing 200 when the air conditioner is in the off state, and the outer surface 114 of the air guide plate body 110 refers to the side of the air guide plate body 110 facing the outside of the air conditioner housing 200 when the air conditioner is in the off state. The outer surface 114 of the air guide plate body 110 can guide the airflow of the air conditioner.

[0038] The air guide plate 100 provided in this embodiment of the application has a cavity 120 provided on the air guide plate body 110. The cavity 120 is hourglass-shaped along the direction from the first edge 111 to the second edge 112 of the air guide plate body 110, and a movable medium 130 that can move under the action of gravity is provided inside the cavity 120. Thus, when the air conditioner is cooling, the free movement of the movable medium 130 causes the air guide plate body 110 to become unbalanced, so that the air guide plate body 110 automatically adjusts the air guiding angle under the influence of gravity, thereby changing the space for the mixing of hot and cold air (i.e., disrupting the space for the mixing of hot and cold airflows), avoiding condensation at the lower edge of the air guide plate body 110, and thus improving the user experience. Here, the lower edge of the air guide plate body 110 refers to the lower of the first edge 111 and the second edge 112 when the air conditioner is cooling.

[0039] Specifically, the cavity 120 includes a first cavity 121, a second cavity 122, and a channel 123. The first cavity 121, the channel 123, and the second cavity 122 are arranged sequentially along the direction from the first edge 111 to the second edge 112, forming an hourglass-shaped structure. The channel 123 connects the first cavity 121 and the second cavity 122. The first cavity 121 is located near the first edge 111, and the second cavity 122 is located near the second edge 112.

[0040] Optionally, the width L1 of channel 123 is 0.25mm to 0.35mm. This allows control over the movement speed of the medium within a reasonable range, preventing it from moving too fast or too slow, thus achieving a better anti-condensation effect. For example, the width L1 of channel 123 can be 0.2mm, 0.21mm, 0.22mm, 0.23mm, 0.24mm, 0.25mm, 0.26mm, 0.27mm, 0.28mm, 0.29mm, 0.3mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, or any range between two values, and can be set according to actual needs. Experimental verification shows that when the width L1 of channel 123 is 0.3mm, no condensation occurs on the lower edge of the air guide plate body 110 during 4 hours of continuous cooling by the air conditioner, and the movable medium 130 is completely moved from one of the first cavity 121 to the other of the second cavity 122.

[0041] In some embodiments of this application, the air guide plate body 110 is a transparent structure, that is, the air guide plate body 110 is made of a transparent material. By making the air guide plate body 110 a transparent structure, the movable medium 130 inside the cavity 120 is visible. Thus, after the air conditioner has finished cooling and the air guide plate 100 has closed the air outlet 201, the air conditioner's operating time can be inferred by observing the amount of movable medium 130 in the second cavity 122.

[0042] Optionally, the cavity 120 includes a first side surface 124 disposed near the outer surface 114 of the air guide plate body 110. The average distance L2 between the first side surface 124 and the outer surface 114 of the air guide plate body 110 is 1mm to 1.5mm, so as to ensure both the visualization effect of the movable medium 130 and the structural strength of the air guide plate body 110.

[0043] For example, the average distance L2 between the first side 124 of the cavity 120 and the outer surface 114 of the air guide plate body 110 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm or any range between two values, and can be set according to actual needs.

[0044] In some embodiments of this application, the air guide plate 100 further includes a rotating arm 140, one end of which is rotatably connected to the air guide plate body 110, and the other end of which is rotatably connected to the air conditioner housing 200. By providing the rotating arm 140, the rotation amplitude of the air guide plate body 110 can be increased, thereby improving the air guiding effect of the air guide plate body 110.

[0045] Optionally, the other end of the rotating arm 140 is bent toward the second edge 112 away from the air guide plate body 110 to form an arc structure, which can further increase the rotation range of the air guide plate body 110 and improve the air guiding effect of the air guide plate body 110.

[0046] Optionally, the air guide plate body 110 is provided with a connecting part 151, which is located near the first edge 111. The air guide plate body 110 is connected to one end of the rotating arm 140 through the connecting part 151. Specifically, the connecting part 151 is provided on the inner surface 113 of the air guide plate body 110, and the connecting part 151 is provided with a first shaft hole. One end of the rotating arm 140 is provided with a first rotating shaft, which is rotatably inserted into the first shaft hole to achieve a rotatable connection between the rotating arm 140 and the air guide plate body 110. Alternatively, the connecting part 151 may be provided with a first rotating shaft, and one end of the rotating arm 140 may be provided with a first shaft hole, which is rotatably inserted into the first shaft hole. This also achieves a rotatable connection between the rotating arm 140 and the air guide plate body 110.

[0047] In some embodiments of this application, the air guide plate body 110 is provided with a driving part 152 and a rotating part 153 at both ends along its length direction. The rotating part 153 is used to rotatably connect with the air conditioner housing 200, and the driving part 152 is used to connect with a driving component, which can drive the air guide plate body 110 to rotate. By providing the driving part 152 and the rotating part 153, it is convenient to rotatably install the air guide plate body 110 on the air conditioner housing 200, and to rotate around an axis parallel to the length direction of the air guide plate body 110 under the drive of the driving component, so as to realize the functions of closing the air outlet 201 and guiding the air.

[0048] Optionally, the drive unit 152 is provided with a connecting hole, and the drive component is a motor. The motor shaft of the motor passes through the connecting hole so that the drive component can drive the air guide plate body 110 to rotate. Specifically, the side of the motor shaft is provided with at least one first plane, and the wall of the connecting hole is provided with at least one second plane. The motor shaft is inserted into the connecting hole, and the first plane and the second plane are in one-to-one correspondence to fit together, so as to realize the connection between the motor shaft and the air guide plate body 110, so that the air guide plate body 110 can rotate synchronously with the motor shaft.

[0049] Optionally, the rotating part 153 is provided with a second rotating shaft 154, and the air conditioner housing 200 is provided with a second shaft hole. The second rotating shaft 154 is rotatably inserted into the second shaft hole to achieve a rotatable connection between the air guide plate body 110 and the air conditioner housing 200. Alternatively, the rotating part 153 may be provided with a second shaft hole, and the air conditioner housing 200 may be provided with a second rotating shaft 154. The second rotating shaft 154 is rotatably inserted into the second shaft hole, which also achieves a rotatable connection between the air guide plate body 110 and the air conditioner housing 200.

[0050] This application also provides an air conditioner, such as... Figures 7-14 As shown, the air conditioner includes a housing 200 and an air guide plate 100. The specific structure of the air guide plate 100 is as described in the above embodiments. The housing 200 is provided with an air outlet 201, and the air guide plate 100 is rotatably disposed at the air outlet 201. Since this air conditioner adopts all the technical solutions of all 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.

[0051] The casing 200 contains an air duct 202 and a heat exchanger 400. The air inlet and outlet of the air duct 202 are connected to the air inlet and air outlet 201, respectively. The heat exchanger 400 is located between the air inlet and the air inlet of the air duct 202. A fan 300 is installed in the air duct 202. When the fan 300 is running, it guides the airflow formed in the casing 200 to the air outlet 201 through the air duct 202. The air guide plate 100 is rotatably installed at the air outlet 201 to open and close the air outlet 201.

[0052] Optionally, the air conditioner also includes a drive unit, which is mounted on the housing 200 and can drive the air guide plate 100 to rotate. By including the drive unit, the rotation of the air guide plate 100 can be electrically controlled, making the control of the air guide plate 100 more intelligent.

[0053] In some embodiments of this application, the air guide plate 100 has a lower air guide position and a closed position during rotation, that is, the air guide plate body 110 can switch between the lower air guide position and the closed position; the air conditioner has a cooling mode and a shutdown state.

[0054] like Figures 9-14 As shown, the air conditioner is configured such that when the air conditioner is in cooling mode, the air guide plate 100 is in the lower air guide position. At this time, the inner surface 113 of the air guide plate body 110 faces the upper front of the housing 200, and the outer surface 114 of the air guide plate body 110 faces the lower rear of the housing 200, so that the airflow is sent downward (i.e., downward airflow). The position of the second edge 112 of the air guide plate body 110 is lower than the first edge 111 of the air guide plate body 110. It can be understood that during the air conditioning cooling process, the movable medium 130 will move in the direction from the first edge 111 to the second edge 112, that is, the movable medium 130 moves from the first cavity 121 to the second cavity 122. The free movement of the movable medium 130 causes the air guide plate body 110 to become unbalanced, so that the air guide plate body 110 automatically adjusts the air guide angle under the influence of gravity, so as to change the space for the mixing of cold and hot air (i.e., to disrupt the space for the mixing of cold and hot airflow), and avoid condensation on the air guide plate body 110.

[0055] Specifically, when the air conditioner first starts operating in cooling mode, the air guide plate 100 is in its initial position, and its state at this time is as follows: Figure 9 and Figure 10 As shown, while the air conditioner continues to operate in cooling mode, the air guide vane 100 will rotate in a clockwise direction (i.e., Figure 10 (In the direction of the arrow) rotates; after the air conditioner has been running in cooling mode for time T1, the air guide plate 100 rotates clockwise by a first angle θ1. At this time, the state of the air guide plate 100 is as follows. Figure 11 and Figure 12 As shown; after the air conditioner has been running in cooling mode for time T2, the air guide plate 100 has rotated clockwise by a second angle θ2, where θ2 > θ1 and T2 > T1. At this time, the state of the air guide plate 100 is as follows: Figure 13 and Figure 14 As shown. For example, time T1 can be 2 hours and time T2 can be 4 hours.

[0056] like Figure 7 and Figure 8 As shown, the air conditioner is configured such that when the air conditioner is off, the air guide plate 100 is in the closed position. At this time, the air guide plate body 110 closes the air outlet 201 and its inner surface 113 faces the rear upper part of the casing 200. The second edge 112 of the air guide plate body 110 is higher than the first edge 111 of the air guide plate body 110. Therefore, the movable medium 130 within the cavity 120 moves in the direction from the first edge 111 to the second edge 112, i.e., the movable medium 130 moves from the second cavity 122 to the first cavity 121. Specifically, when the air conditioner receives a shutdown command, the air guide plate 100 rotates counterclockwise to the closed position.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0058] 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.
