[0032] In the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The panel 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, according to the panel 100 of the embodiment of the utility model, the panel 100 is applied to the air-conditioning indoor unit 1000, and the panel 100 includes a panel body 10 and a heating element 20. The panel body 10 has an edge portion 10a, and the edge portion 10a is located on the long side of the panel body 10 and close to the air outlet 200a of the air-conditioning indoor unit 1000; the heating element 20 is arranged on the panel body 10 and is arranged close to the edge portion 10a.

[0036] The panel body 10 may refer to a plate-shaped component, which is used to be installed on the casing 200 of the air conditioner indoor unit 1000. Since the edge portion 10a is located on the long side of the panel body 10 and close to the air outlet 200a of the air conditioner indoor unit 1000, when the air outlet 200a discharges hot air or cold air, the edge portion 10a is more likely to have uneven heat and cold than other positions of the panel body 10, that is, the area where the edge portion 10a is located on the panel body 10 is more likely to have a temperature difference and form condensation. By arranging a heating element 20 close to the edge portion 10a on the panel body 10, the heating element 20 is powered on to generate heat to heat the edge portion 10a, so that the temperature of the edge portion 10a is kept uniform, and the occurrence of uneven heat and cold is reduced, thereby reducing the probability of temperature difference in the edge portion 10a, reducing the occurrence of condensation in the edge portion 10a, and further reducing the probability of condensation in the panel body 10.

[0037] Since the heating element 20 can heat the edge portion 10a, compared with heating other positions of the panel body 10, the temperature difference can be eliminated by heating the position where the uneven temperature first occurs on the panel body 10, so that the condensation can be eliminated more timely and the condensation elimination effect is better. The heating element 20 can be, but is not limited to, a heating wire (see Figure 1 )、Heating belt (reference Figure 2 ), heating tubes and graphene heating elements, etc.

[0038] According to the panel 100 of the embodiment of the utility model, a heating element 20 is arranged on the panel body 10 near the edge portion 10a. The heating element 20 can heat the position of the edge portion 10a, thereby reducing the temperature difference generated by the edge portion 10a when the air outlet 200a of the air-conditioning indoor unit 1000 discharges air, which is beneficial to improving the problem of uneven heating and cooling at the edge portion 10a, reducing the probability of condensation on the panel 100, and reducing the probability of dripping risk.

[0039] In some embodiments of the present invention, the heating element 20 extends along the length direction of the edge portion 10 a , and any end of the heating element 20 extends to a short side close to the panel body 10 .

[0040] It can be understood that the length directions of the heating element 20 and the edge portion 10a are consistent. The length of the heating element 20 and the length of the edge portion 10a can be equal, or the two ends of the heating element 20 are respectively close to the short sides of the two ends of the length direction of the panel body 10, that is, the length of the heating element 20 is slightly smaller than the length of the edge portion 10a.

[0041] In the above technical solution, the heating element 20 is a component with a longer length, which can heat the edge portion 10a along the length direction of the edge portion 10a. The overall heating speed of the edge portion 10a is relatively fast, and the uneven temperature can be eliminated more timely, which can further shorten the time for eliminating condensation and is beneficial to improving the effect of eliminating condensation.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the panel body 10 is provided with a receiving groove 10b, the heating element 20 is arranged in the receiving groove 10b, and the panel 100 further includes a cover plate 30, which is covered at the notch of the receiving groove 10b.

[0043] The receiving groove 10b can provide the installation space required by the heating element 20. The heating element 20 can be fixed in the cavity formed by the receiving groove 10b and the cover plate 30 by covering the notch of the receiving groove 10b with the cover plate 30. The above-mentioned method for installing the heating element 20 is relatively simple, and can improve the installation reliability of the heating element 20 and reduce the probability of the heating element 20 being separated from the panel body 10.

[0044] Moreover, in the above technical solution, the cover plate 30 and the receiving groove 10b can be easily assembled in a detachable manner, which is convenient for the later installation or removal of the heating element 20 and is conducive to the maintenance of the heating element 20 when the heating element 20 is damaged.

[0045] In some embodiments of the present invention, the cover plate 30 and the receiving groove 10 b may be detachably connected by, but not limited to, bonding, snap connection, screw connection, and the like.

[0046] In some embodiments of the present invention, the panel body 10 has an inner side close to the air outlet 200 a , and the receiving groove 10 b and the cover plate 30 are disposed on the inner side.

[0047] refer to Figure 1 and Figure 2 The “inside” may be the rear side of the panel body 10 in the figure. In the above technical solution, by arranging the receiving groove 10b and the cover plate 30 on the inner side of the panel body 10, the receiving groove 10b and the cover plate 30 can be hidden, thereby ensuring the flatness of the outer side of the panel body 10 and improving the aesthetics of the panel 100.

[0048] In some embodiments of the present invention, Figure 2 As shown, the heating element 20 has a first plane 20a, the first plane 20a faces the panel body 10, and a first adhesive layer 40 is provided between the first plane 20a and the receiving groove 10b.

[0049] It can be understood that the heating element 20 is a component with a long length, and can contact the panel body 10 through the first plane 20a. The adoption of this solution can realize surface contact connection between the heating element 20 and the panel body 10, and the heating element 20 and the panel body 10 can be fully in contact with each other, and have a large heat exchange surface, which can reduce the time for the heating element 20 to heat the panel body 10 and improve the heating efficiency of the heating element 20 to the panel body 10. Secondly, the first plane 20a can be bonded to the receiving groove 10b through the first adhesive layer 40, which can improve the heat conduction efficiency between the heating element 20 and the panel body 10 on the one hand, and improve the connection reliability between the heating element 20 and the receiving groove 10b on the other hand, and the heating element 20 is not easy to separate from the panel body 10, which can improve the reliability of the panel 100.

[0050] In some embodiments of the present invention, the first adhesive layer 40 may be, but is not limited to, a 3M adhesive layer, a structural adhesive layer, thermal conductive silicone grease, and the like.

[0051] In some embodiments of the present invention, Figure 2 As shown, the heating element 20 has a second plane 20 b , the second plane 20 b faces the cover plate 30 , and a heat insulating member 50 is disposed between the second plane 20 b and the cover plate 30 .

[0052] It can be understood that the second plane 20b of the heating element 20 can be parallel to the cover plate 30, and the cover plate 30 can fix the heating element 20 by acting on the second plane 20b. With this solution, there is a larger contact surface between the cover plate 30 and the heating element 20, and the cover plate 30 has a better fixing effect on the heating element 20, and the fixing is also more firm. The heat insulation 50 can play a role of heat preservation and heat insulation between the second plane 20b and the cover plate 30, reduce the heat transfer to the cover plate 30, so that the heat generated by the heating element 20 can be used to heat the edge portion 10a as much as possible, and improve the anti-condensation effect of the panel 100.

[0053] In some embodiments of the present invention, the thermal insulation member 50 may be, but is not limited to, aluminum foil, rock wool board, glass wool, asbestos, and the like.

[0054] In some embodiments of the present invention, the heating element 20 may be in the shape of, but not limited to, a plate or a strip.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the panel body 10 includes a first plate body 101 and a second plate body 102. The second plate body 102 is arranged on a side of the first plate body 101 close to the air outlet 200a. The second plate body 102 and the first plate body 101 jointly define a receiving groove 10b.

[0056] It can be understood that by configuring the panel body 10 to include a first plate body 101 and a second plate body 102, the panel body 10 is a split structural design. Compared with the panel body 10 being an entire component, the split design can reduce mold complexity and help reduce manufacturing costs.

[0057] Since the second plate body 102 and the first plate body 101 jointly define a receiving groove 10b, a through hole is opened on the second plate body 102 to form the receiving groove 10b with the first plate body 101. When the heating element 20 is placed in the receiving groove 10b, the distance between the heating element 20 and the outer side surface of the first plate body 101 can be reduced. Since the receiving groove 10b is formed on the panel body 10, the thickness of the portion corresponding to the heating element 20 on the panel body 10 is relatively small. When the heating element 20 generates heat, the heat can be transferred to the outer side surface of the first plate body 101 relatively quickly, which is beneficial to reduce the probability of condensation forming on the outer side surface of the first plate body 101.

[0058] In some embodiments of the present invention, the first plate 101 and the second plate 102 may be connected by, but not limited to, snap connection, screw connection, bonding, etc. Exemplarily, a second adhesive layer 60 is provided between the first plate 101 and the second plate 102 .

[0059] In some embodiments of the present invention, the first plate body 101 may be, but is not limited to, a glass plate, a metal plate, a rock plate, etc., and the second plate body 102 may be, but is not limited to, a plastic plate, a sheet metal plate, etc.

[0060] In some embodiments of the present invention, Figure 2 As shown, the edge portion 10a has a first edge line 10c, and the heating element 20 has a second edge line 20c. The second edge line 20c is close to the edge portion 10a, and the distance between the second edge line 20c and the first edge line 10c is 10 mm to 15 mm.

[0061] The distance between the second sideline 20c and the first sideline 10c may be H, where H may be, but is not limited to, 10 mm, 10.5 mm, 11 mm, 11.2 mm, 11.8 mm, 12 mm, 12.4 mm, 12.7 mm, 13 mm, 13.5 mm, 14 mm, 14.3 mm, 14.8 mm, 15 mm, and the like.

[0062] If the distance between the second sideline 20c and the first sideline 10c is less than 10 mm, the distance between the heating element 20 and the edge portion 10a is relatively small, and the installation margin of the heating element 20 on the panel body 10 is relatively small, which is not conducive to the installation of the heating element 20 on the panel body 10. If the distance between the second sideline 20c and the first sideline 10c is greater than 15 mm, the distance between the heating element 20 and the edge portion 10a is relatively large, which affects the heating effect of the heating element 20 on the edge portion 10a. If the heating power of the heating element 20 is increased, the fire protection requirements will be increased, and the safety risks and power consumption will increase.

[0063] In the above technical solution, by setting the distance between the second edge line 20c and the first edge line 10c within the range of 10mm to 15mm, on the one hand, a suitable space can be reserved in the panel body 10 to facilitate the installation of the heating element 20, and on the other hand, the heating effect of the heating element 20 on the edge portion 10a can be ensured, so that the heating element 20 can heat the edge portion 10a more quickly.

[0064] In some embodiments of the present invention, the heating power of the heating element 20 is less than or equal to 15W.

[0065] It can be understood that the heating power of the heating element 20 can be but not limited to 15W, 14W, 13W, 12W, 11W, 10W, 9W, 8W, 7W, 6W, 5W, 4W, etc. In the above technical solution, by setting the heating power of the heating element 20 to be less than or equal to 15W, the heating element 20 can have a suitable heating power, so that the edge portion 10a can be quickly heated. On the other hand, the electrical components with a power of less than 15W do not need to be provided with a separate fireproof device, which is safe and reliable, and the cost is relatively low, which can improve the safety of the panel 100.

[0066] like Figure 3 and Figure 4 As shown, the air conditioner indoor unit 1000 according to the embodiment of the utility model includes a casing 200 and a panel 100, the casing 200 is provided with an air outlet 200a; the panel body 10 is arranged on the casing 200, and the edge portion 10a is arranged close to the air outlet 200a.

[0067] According to the air-conditioning indoor unit 1000 of the embodiment of the utility model, by adopting the panel 100, the uneven heating and cooling of the panel 100 near the air outlet 200a can be improved, the probability of condensation on the panel 100 can be reduced, the probability of water dripping on the panel 100 can be reduced, and the working reliability and safety of the air-conditioning indoor unit 1000 can be improved.

[0068] In some embodiments of the utility model, the air conditioning indoor unit 1000 also includes a temperature detection element and a humidity detection element, which are arranged on the casing 200. The air conditioning indoor unit 1000 also includes a controller, which is electrically connected to the heating element 20, the temperature detection element and the humidity detection element.

[0069] In the air conditioner indoor unit 1000, the controller can jointly control the heating element 20 to work according to the detection information of the temperature detection element and the humidity detection element. It can be understood that when the detection values ​​of the temperature detection element and the humidity detection element are the set values, the controller controls the heating element 20 to turn on and heat. For example, when the temperature detection element detects that the outdoor temperature is 16 degrees and the humidity detection element detects that the outdoor humidity is 70%, the controller controls the heating element 20 to turn on.

[0070] It should be noted that if Figure 3 and Figure 4As shown, the air conditioner indoor unit 1000 also includes a heat exchanger 300, a wind wheel 400, a pipeline system, an air guide plate mechanism 500, etc. The housing 200 is also provided with an air inlet 200b. When the air conditioner indoor unit 1000 is working, the wind wheel 400 drives the air to enter the air duct in the housing 200 from the air inlet 200b, and heat exchange is performed through the heat exchanger 300. Then the wind wheel 400 drives the air after heat exchange to blow out from the air outlet 200a, and the air guide plate mechanism 500 is arranged at the air outlet 200a to guide the blown air. Among them, the panel 100 can be provided with a display component, and the display component can be connected to the controller to display information of the air conditioner indoor unit 1000.

[0071] Other structures and operations of the air-conditioning indoor unit 1000 according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.

[0072] In the description of this specification, the description with reference to the terms "embodiment", "example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
