Referring to fig. 1 and 2, in order to provide an air conditioner 2000 and a panel assembly 1000 according to an embodiment of the present invention, the panel assembly 1000 is installed on the air conditioner 2000, for example, in a bathroom air conditioner. The bathroom air conditioner includes a housing 2100, a fan 2110, an electric control board (not shown) and other components are disposed in the housing 2100, and the panel assembly 1000 can be connected to the housing 2100 to protect the fan 2110 and the electric control board. The bathroom air conditioner is generally installed on a ceiling, and the panel assembly 1000 includes a panel 100 generally facing the ground or in a state generally parallel to the ground. Since the humidity of the air inside the bathroom is high, when the temperature difference between the inside and the outside of the panel 100 is large, the condensation is easily generated. And the utility model discloses panel assembly 1000 can improve the homogeneity of panel heating, reduces the condensation phenomenon.

Referring to fig. 2, 3 and 4, in an embodiment of the present invention, a panel assembly 1000 includes a panel 100, a heating belt 300 and a cover plate 200. The panel 100 has a substantially square plate shape, the heating tape 300 is located inside the panel 100, and the inside of the panel 100 means: when the panel 100 is connected to the housing 2100, the panel 100 is close to the inner side of the housing 2100, or close to the fan 2110. The heating temperature of the heating belt 300 is too low to have a dewing prevention effect, and too high heating temperature easily causes the panel 100 to be deformed and increases power consumption, so the heating temperature of the heating belt 300 may be between 30 to 60 ℃. The cover plate 200 is substantially in the shape of a square plate, the cover plate 200 covers a side of the heating belt 300 away from the panel 100 and is fixedly connected to the panel 100, and the cover plate 200 is used for fixing the heating belt 300 between the panel 100 and the cover plate 200. It is understood that the panel 100 and the cover plate 200 may also be other shapes, such as a circle, a triangle, a trapezoid, etc., and the suitable scheme is selected according to the actual situation, and the invention is not limited in detail herein.

Referring to fig. 2 and 5, in an embodiment of the present invention, the panel 100 is provided with a clip 110, the clip 110 is located on one side of the panel 100 facing the cover plate 200, and the cover plate 200 is provided with an avoiding hole 230 and a blocking pillar 220. When the cover plate 200 is fastened to the panel 100, the fastening member 110 is inserted into the avoiding hole 230 and fastened to the fastening post 220, so that the cover plate 200 is fixedly connected to the panel 100. Wherein, joint spare 110, dodge hole 230 and screens post 220 and all have a plurality ofly, and a plurality of joint spare 110, a plurality of dodge hole 230 and a plurality of screens post 220 equally divide and do not follow the extending direction interval setting of heating band 300, or say so along the extending direction interval setting of holding tank 210, and it is inseparabler to enable laminating between heating band 300 and the panel 100, improves the heating efficiency of heating band 300 and improves the homogeneity that panel 100 heated. It should be noted that the cover plate 200 may also be provided with the avoiding hole 230 instead of the positioning column 220, and the clamping member 110 is directly connected to the cover plate 200. The utility model discloses the concrete scheme of selecting according to actual conditions, the utility model discloses no longer specifically limit herein.

It can be understood that the heating belt 300 can heat the panel 100 to reduce the temperature difference between the inside and the outside of the panel 100, thereby reducing the occurrence of condensation and improving the user experience. The cover plate 200 covers the heating band 300, so that the influence of water vapor in a bathroom on the heating band 300 can be reduced, the heating band 300 can be protected, and the safety and the service life of the heating band 300 can be improved.
