[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the air guide plate of the air conditioner provided by the embodiment of the utility model includes an air guide plate body 100 and a sealing component 200. The air guide plate body 100 is provided with a cavity 110 and an opening 120. The end of the cavity 110 along the air supply direction of the air conditioner is connected to the opening 120, and the sealing component 200 is sealed in the opening 120.

[0027] The air guide plate of the air conditioner of the embodiment of the utility model is arranged at the air outlet 310 of the air conditioner. The air guide plate can open and close the air outlet 310 by rotating. When the air outlet 310 is opened, the cold air or hot air in the inner cavity of the air conditioner is discharged through the air outlet 310. The air guide plate is mainly composed of an air guide plate body 100 combined with a sealing component 200. The air guide plate body 100 itself forms a cavity 110 and an opening 120 connected to the cavity 110. The sealing component 200 is sealed at the opening 120 to make the cavity 110 a sealed cavity. Thus, the air guide plate forms a structure with a sealed cavity inside. The sealed cavity can change the heat conduction effect of the air guide plate, reduce the heat conduction performance of the air guide plate, prevent the difference in temperature and humidity inside and outside the air conditioner from causing condensation on the outer surface of the air guide plate, and at the same time reduce the cold or heat loss of the air supply of the air conditioner on the air guide plate, thereby improving the cooling or heating effect of the air supply of the air conditioner.

[0028] Furthermore, the air guide plate body 100 is made into a structure that can enclose a cavity 110 having an opening 120, and then the opening 120 is sealed with a sealing component 200, which simplifies the injection molding of the air guide plate, makes the manufacturing process simple and reliable, and facilitates assembly.

[0029] According to an embodiment provided by the utility model, the air guide plate body 100 includes a first guide plate 130 and a second guide plate 140, the first end of the first guide plate 130 is closed and connected with the first end of the second guide plate 140, the second end of the first guide plate 130 and the second end of the second guide plate 140 surround an opening 120, and the first guide plate 130 is arranged on a side of the second guide plate 140 facing the inner cavity of the air conditioner.

[0030] In this embodiment, the main part of the air guide plate body 100 is the first guide plate 130 and the second guide plate 140. When the air guide plate closes the air outlet 310 of the air conditioner, the first guide plate 130 is located in the inner cavity of the air conditioner, and the second guide plate 140 is located on the surface of the air outlet 310 of the air conditioner. When the air guide plate opens the air outlet 310 of the air conditioner, cold air or hot air flows out along the surface of the first guide plate 130.

[0031] The first end and the second end of the first guide plate 130 are sequentially arranged along the air supply direction of the air conditioner, and the first end and the second end of the second guide plate 140 are sequentially arranged along the air supply direction of the air conditioner. The first end of the first guide plate 130 is closed and connected with the first end of the second guide plate 140, and there is a certain distance between the second end of the first guide plate 130 and the second end of the second guide plate 140, that is, an opening 120 is formed, so the first end of the first guide plate 130 is connected to the second guide plate 140, and then gradually tilts away from the second guide plate 140 along the air supply direction until the second end of the first guide plate 130 and the second guide plate 140 form an opening 120, so that the cross-section of the air guide plate body 100 perpendicular to its length direction is fan-shaped, and the space between the first guide plate 130 and the second guide plate 140 forms a cavity 110.

[0032] In this embodiment, the structures of the first guide plate 130 and the second guide plate 140 cooperate to construct the design of the cavity 110, so that the air guide body 100 forms a structure with thickness variation along the air supply direction. In other embodiments, the relative distance between the first guide plate 130 and the second guide plate 140 and the inclination angle of the first guide plate 130 relative to the second guide plate 140 can be changed accordingly according to the thickness variation requirement of the air guide body 100 and the size requirement of the cavity 110.

[0033] According to an embodiment provided by the utility model, the first guide plate 130 is convexly curved toward the second guide plate 140, and the second guide plate 140 is convexly curved toward the outside of the air conditioner. In this embodiment, both the first guide plate 130 and the second guide plate 140 are arc-shaped plates, and are arc-shaped plates that convex toward the outside of the air conditioner compared to the inner cavity of the air conditioner.

[0034] The second guide plate 140 is bent at a certain curvature, and its main function is to match the appearance style of the air conditioner. When the air supply outlet 310 of the air conditioner is closed, it can better fit the outer shape of the air conditioner. The first guide plate 130 is also bent at a certain curvature. The surface of the first guide plate 130 away from the second guide plate 140 is the air supply cover through which the air conditioner passes when supplying air. The air supply surface 131 is in the form of a convex and curved outward, and can guide the airflow of the air supply outlet 310 when the air supply outlet 310 of the air conditioner is opened, so that the airflow can flow out smoothly to the external environment.

[0035] According to an embodiment provided by the utility model, the curvature of the first guide plate 130 is greater than that of the second guide plate 140. In this embodiment, the curvature of the second guide plate 140 is adapted to the shape of the shell of the air conditioner, and the curvature of the first guide plate 130 is adapted to the air supply angle requirement of the air conditioner. The curvature of the first guide plate 130 is greater than that of the second guide plate 140. When the length and width of the first guide plate 130 are constant, the size of the opening 120 can be further increased, that is, the volume of the cavity 110 is increased, and then the thickness of the sealed cavity of the air guide plate is increased.

[0036] In other embodiments, the curvature of the first guide plate 130 and the curvature of the second guide plate 140 may be selected according to actual needs.

[0037] According to an embodiment provided by the utility model, the air guide plate body 100 further includes side plates 150, which are arranged at both ends of the first guide plate 130 perpendicular to the air supply direction of the air conditioner, and the side plates 150 are closed and connected to both the first guide plate 130 and the second guide plate 140. In this embodiment, a side plate 150 is further arranged between the first guide plate 130 and the second guide plate 140, and the two side plates 150 are respectively arranged at both ends of the first guide plate 130 along its length direction, and one side edge of the side plate 150 is closed and connected to the first guide plate 130, and the other side edge of the side plate 150 is closed and connected to the second guide plate 140, that is, the first guide plate 130, the second guide plate 140 and the two side plates 150 jointly enclose a cavity 110, and an opening 120 is enclosed at the end of the first guide plate 130 along the air supply direction.

[0038] The side plate 150 is shaped to fit the fan shape of the first guide plate 130 and the second guide plate 140 , thereby improving the structural strength of the connection between the first guide plate 130 and the second guide plate 140 , and at the same time improving the connection strength between the first guide plate 130 and the second guide plate 140 , supporting the cavity 110 and ensuring the sealing effect of the cavity 110 .

[0039] According to an embodiment provided by the utility model, a plurality of guide plates 160 are provided on the surface of the first guide plate 130 close to the inner cavity of the air conditioner, the guide plates 160 are vertically connected to the first guide plate 130, and the plurality of guide plates 160 are evenly distributed. In this embodiment, the surface of the first guide plate 130 close to the inner cavity of the air conditioner is the air supply surface 131, that is, when the air conditioner supplies air, the airflow passes through the air supply surface 131 and enters the external environment, and a plurality of guide plates 160 are provided on the air supply surface 131, the guide plates 160 are vertically arranged on the first guide plate 130, and a channel is formed between two adjacent guide plates 160, that is, the extension direction of the channel is the air supply direction of the air conditioner.

[0040] The air supply surface 131 of the first guide plate 130 is designed with a guide plate 160 to form a guide structure. The multiple guide plates 160 are evenly distributed in the length direction of the first guide plate 130 to form multiple channels with the same width and length. When the air flow passes through the air supply surface 131, it can be divided by each channel, which effectively improves the guidance of the air flow, so that it can be blown more evenly and farther.

[0041] In other embodiments, the number of guide plates 160 and the shape and size of the guide plates 160 can be designed and adjusted according to actual air supply needs.

[0042] According to an embodiment provided by the utility model, the sealing component 200 includes an insulating portion 210, and the cavity 110 is divided into a first insulating cavity 111 and a second insulating cavity 112 along the air supply direction of the air conditioner. The insulating portion 210 is inserted into the first insulating cavity 111 through the opening 120, and the second insulating cavity 112 is in a vacuum or air-filled state.

[0043] In this embodiment, the sealing component 200 is inserted into the cavity 110 to seal the opening 120. The cavity 110 is divided into two parts, one part is the second insulation cavity 112 close to the first end of the first guide plate 130 and the second guide plate 140, and the other part is the first insulation cavity 111 close to the second end of the first guide plate 130 and the second guide plate 140. That is, when the air conditioner is supplying air, the airflow passes through the air supply surface 131 of the first guide plate 130, that is, it passes through the first insulation cavity 111 and the second insulation cavity 112 corresponding to the air supply surface 131 in sequence. The first insulation cavity 111 and the second insulation cavity 112 can effectively reduce the heat and cold transfer of the airflow, thereby avoiding the increase of the temperature and humidity difference between the second guide plate 140 and the outside world to generate condensation.

[0044] In this embodiment, the heat insulating part 210 can be made of heat insulating materials such as foam. After the heat insulating part 210 is inserted into the cavity 110, the part of the cavity 110 filled with the heat insulating part 210 is the first heat insulating cavity 111, and the remaining part of the cavity 110 is the second heat insulating cavity 112, that is, the first heat insulating cavity 111 is filled with foam, and the second heat insulating cavity 112 is not filled with other materials, and is sealed in an air state, so that the air guide plate forms a structure of first air insulation and then foam insulation. Since the air environment is in a sealed state, it also has a lower thermal conductivity and can also achieve a better insulation effect. With the heat insulating material filled in the first heat insulating cavity 111, on the one hand, sealing is achieved while reducing the amount of insulation material used, and on the other hand, the insulation effect can be improved.

[0045] In other embodiments, a vacuum insulation can be formed in the second insulation cavity 112, and the vacuum insulation can also achieve a good insulation effect. The insulation part 210 can also use other types of insulation materials.

[0046] According to an embodiment provided by the utility model, the sealing component 200 also includes a transition portion 220, which is connected to the insulation portion 210, and the transition portion 220 is located outside the cavity 110. The transition portion 220 is provided with a transition surface 221, and the transition surface 221 connects the first guide plate 130 and the second guide plate 140 to enable a smooth transition between the first guide plate 130 and the second guide plate 140.

[0047] In this embodiment, the sealing component 200 is mainly composed of two parts: an insulation part 210 and a transition part 220. After the insulation part 210 is inserted into the cavity 110, the transition part 220 is exposed outside the cavity 110. The transition part 220 has an arc-shaped transition surface 221, and the arc-shaped transition surface 221 is convex and curved in the direction away from the cavity 110. One side edge of the transition surface 221 is connected to the end of the air supply surface 131 of the first guide plate 130, and the other side edge of the transition surface 221 is connected to the edge of the second end of the second guide plate 140, and the arc-shaped transition form makes the end connection transition between the first guide plate 130 and the second guide plate 140 in the air supply direction smoother.

[0048] When the air outlet 310 of the air conditioner supplies air, the airflow passes through the air supply surface 131 of the first guide plate 130 and then flows to the transition surface 221. The arc-shaped smooth transition of the transition surface 221 can further improve the guiding effect of the air guide plate on the airflow, so that the airflow can be smoothly delivered downward and to a farther direction.

[0049] According to an embodiment provided by the utility model, a plurality of convex strips 230 are provided on the transition surface 221, and the extension direction of each convex strip 230 is perpendicular to the air supply direction. In this embodiment, a convex strip 230 is also provided on the transition surface 221 of the transition portion 220, and the convex strip 230 is a strip-shaped protrusion with a certain length, and the length extension direction of the convex strip 230 is the length direction of the air guide plate body 100, and each convex strip 230 is arranged parallel to each other. When the air conditioner is supplying air, in the process of the airflow passing through the transition surface 221, since the transition surface 221 is an outwardly convex arc surface, the airflow will also produce an upward flow part while flowing downward along the transition surface 221, and the setting of the convex strip 230 can interrupt the upward flow of the airflow and prevent the airflow from flowing upward.

[0050] In this embodiment, the surface of the convex strip 230 is an arc surface, which ensures smooth downward airflow and interrupts the upward airflow, while also ensuring a smooth surface to avoid airflow in other directions caused by the convex strip 230, affecting the air supply effect.

[0051] The air conditioner provided by the present invention is described below. The air guide plates of the air conditioner described below and the air conditioner described above can correspond to each other.

[0052] An embodiment of the utility model further provides an air conditioner, comprising an air guide plate of the air conditioner as described in the above embodiment.

[0053] The air guide plate of the air conditioner of the embodiment of the utility model is a heat-insulating air guide plate, which is connected to the air outlet 310 of the air conditioner casing 300, in order to prevent condensation from falling on the surface of the air guide plate, thereby improving the heating effect while being compatible with the appearance.

[0054] In this embodiment, the second guide plate 140 is provided with a rotating shaft 170, and the rotating shaft 170 is connected to the air conditioner housing 300 at the air outlet 310. The rotating shaft 170 is driven to rotate, which can drive the entire air guide plate to rotate, thereby opening or closing the air outlet 310. When the air guide plate closes the air outlet 310, the entire air guide plate is reset, the second guide plate 140 and the air conditioner housing 300 are integrated, and the first guide plate 130 moves to the top of the water receiving tray 320, so that the condensed water in the first guide plate 130 drips into the water receiving tray 320.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
