DETAILED DESCRIPTION

(6) One embodiment of the disclosure will be described in detail below with reference to the attached drawings, so that the advantages and features of the disclosure can be more easily understood by those skilled in the art. It will be understood that the description of these embodiments is used to help understand this disclosure, and does not constitute a limitation on this disclosure. In addition, the technical features referred to in the various embodiments of the disclosure described below can be combined with each other as long as they do not constitute conflicts with each other.

For example, upper and lower correspond respectively to the upper side and the lower side of the page in FIG. 1.

(8) An embodiment provides an outdoor device, in particular a control panel suitable for the outdoor device and for preventing water accumulation. Referring to FIGS. 1-4, the outdoor device includes a housing 1 which is a box body formed by sheet metal forming or die casting. The housing 1 is provided with a window 10 in which a circuit board and/or component for displaying the state of the outdoor device and for operating the outdoor device is arranged. In this embodiment, the circuit board is specifically a display circuit board 5. The control panel is fixedly arranged on the housing 1, and is used for sealing and covering the display circuit board 5, in order to protect the same. The protection rating of the housing 1 is IP65. The control panel is connected to the housing 1 of outdoor device through sealant and is installed outdoors together with the device, subjecting to outdoor weather conditions such as sunshine and rain.

(9) The control panel for preventing water accumulation specifically includes a display sheet 2, an interface label 3 and an adhesive layer 4 which is connected between the display sheet 2 and the interface label 3 to adhere these two together. The display sheet 2 is transparent or translucent, and in one embodiment made of transparent PC (polycarbonate) material. The display sheet is arranged on the wall of the housing 1 by a sealant, and seals the window, thus protecting the display circuit board 5 from water in the outside atmosphere. The interface label 3 is marked and formed with one or more functional areas through screen printing, and the functional areas allow the user to observe or operate the circuit board and/or component. The material of the interface label 3 is PET (polyethylene terephthalate) or PC. The adhesive layer 4 consists of double-sided tape only filled between the areas of the display sheet 2 and the interface label 3 expect for the functional areas, so that cavities 40 are formed between the functional areas of the interface label 3 and the corresponding areas of the display sheet 2. That is to say, the cavities 40 are a display window, key windows, and indicator windows. The adhesive layer 4 is provided with water guiding grooves 41 for communicating the cavities 40 with the outside so as to drain the accumulated water.

(10) As for the outdoor device of this embodiment, the display circuit board 5 specifically includes an LCD screen 51, four touch sensitive keys 52, and three LEDs 53, which is convenient for the user to check the status of the device or operate the device as needed. Correspondingly, the functional areas on the interface label 3 include a display screen area 31, four key areas 32, and three indicator areas 33. There is no adhesive between the portions of the display sheet 2 and the interface label 3 corresponding to these areas. Therefore, the numbers, shapes, sizes and positions of cavities 40 on the adhesive layer 4 are the same as or correspond to those of functional areas. Thus, the user can observe the information displayed on the LCD screen 51 through the display screen area 31, the cavity 40 corresponding to the display screen area 31, and the display sheet 2. The touch sensitive keys 52 can be operated by pressing the key areas 32, the cavities 40 corresponding to the key areas 32, and the display sheet 2, so as to change the status of the outdoor device. The status of each LED 53 can be observed through the indicator area 33, the cavity 40 corresponding to the indicator area 33, and the display sheet 2, and in combination with the status tags printed on the interface label 3, the current status of the outdoor device can be obtained.

(11) The control panel is, in one embodiment, arranged non-horizontally, i.e. vertically or obliquely. That is to say, the plane where the display sheet 2 is located and the plane where the interface label 3 is located form an angle greater than 0 degrees with respect to the horizontal plane, respectively. The water guiding groove 41 is arranged below the cavity 40 and is communicating with the lower end of the cavity 40. The water guiding groove 41 is, in one embodiment, communicating with the lowest part of the cavity 40 so that under the effect of gravity, the accumulated water in the cavity 40 can flow into the water guiding groove 41. The center line of the water guiding groove 41 is a straight line so that the water flows along the shortest path and is discharged quickly in the direction of the straight line. The water guiding groove 41 is, in one embodiment, strip-shaped and formed by a die cutting process. The length of the water guiding groove 41 is equal to the shortest distance from the lower end of the cavity 40 to the outside. In this embodiment, a special arrangement mode is provided in which the control panel is vertically arranged on the housing 1 and hence the center line of the water guiding groove 41 also extends in the vertical direction, that is, the outlet of the water guiding groove 41 is located directly below the inlet thereof, so that the water flow path is the shortest path.

(12) As shown in FIGS. 3 and 4, as for the cavity 40 corresponding to the display screen area 31, the left and right sides of the lower end of this cavity are directly communicating with the outside through water guiding grooves 41. As for the cavities 40 corresponding to the indicator areas 33, each cavity 40 is communicating with the outside through a water guiding groove 41. As for the upper and lower cavities 40 which are spaced apart in an up-down direction and correspond to the two key areas 32 on the same side, the lower end of the upper cavity 40 and the upper end of the lower cavity 40 are communicating with each other through a first water guiding groove 41a therebetween, and the lower end of the lower cavity 40 is communicating with the outside through a second water guiding groove 41b. The areas corresponding to the LCD screen 51, the touch sensitive keys 52 and the LEDs 53, and the water guiding grooves 41 are free of adhesive, and all these adhesive-free areas are in communication with the outside atmosphere, thus ensuring that all these adhesive-free areas will not form a closed structure after the interface label 3 is pasted.

(13) The display sheet 2 and the interface label 3 are arranged in parallel and spaced apart by 0.1 to 0.3 mm, that is, the thickness of the adhesive layer 4 is 0.1 to 0.3 mm, and hence the thickness of each cavity 40 is 0.1 to 0.3 mm.

(14) The control panel is adapted to be used on the housing 1 of the outdoor device as a control panel of a human-computer interaction interface display window. Such control panel can rapidly and timely discharge accumulated water infiltrated into the adhesive of the interface label 3, eliminating the adverse effects of the accumulated water on the adhesive property, preventing failure of touch sensitive keys, and preventing the display window from being obscured due to immersion in water.

(15) The embodiments described above are merely for illustrating the technical concept and characteristics of this disclosure. These embodiments are embodiments which do not limit the protection scope of this applicant, and the purpose thereof is to enable those skilled in the art to understand the contents of this disclosure and implement it accordingly. Any equivalent transformation or modification made according to the spirit of the disclosure shall fall in the protection scope of the disclosure.
