The door 1 includes a handle groove 3 and a handle groove wall 30 defining the handle groove 3, and fingers of a user may be inserted into the handle groove 3 to grasp the door 1 to pull the door 1 open.
In the present embodiment, the handle groove 3 is provided at a longitudinal side of the door 1. It should be understood that in further embodiments, the handle slot 3 may also be located on a lateral side of the door 1 (e.g., an upper or lower side of the door).
The door 1 includes a heat dissipation duct 5 to discharge heat generated from the display device 2 to the outside of the door 1.
In the present embodiment, the handle groove wall 30 is provided with a first ventilation opening 31 for communicating the heat dissipation air duct 5 and the handle groove 3.
In the present embodiment, the first ventilation opening 31 is provided in the bottom wall facing the entrance of the handle groove 3.
The handle slot wall 30 may be provided with a plurality of first ventilation openings 31, and these first ventilation openings 31 are distributed at one end of the bottom wall 301. In this embodiment, the first ventilation openings 31 are distributed at the lower end of the bottom wall of the handle slot wall 30.
The door 1 includes a second ventilation opening 51 communicating the heat dissipation duct 5 with the outside. The second ventilation opening 51 is located at a lateral side of the door, perpendicular to a longitudinal side of the door 1 where the handle groove 3 is provided. The two ends of the heat dissipation duct 5 communicating with the outside are distributed on the two vertical sides of the door 1, which is advantageous to increase the contact/cooling path between the heat dissipation duct 5 and the display device 2. In the present embodiment, the second ventilation opening 51 is located at the top wall of the door 1 to increase the distance between the second ventilation opening 51 and the first ventilation opening 31 located at the lower end of the bottom wall 301 of the handle groove 3. It is understood that when the first ventilation opening 31 is located at the upper end of the handle groove 301, the second ventilation opening 51 may be provided at the bottom wall of the door 1.
As shown in fig. 4, the installation chamber 140 is divided into a first chamber section 1401 and a second chamber section 1402 with respect to the center plane X thereof, the door 1 is divided into a first door section 1a having the first chamber section 1401 and a second door section 1b located on the other side with respect to the center plane X of the installation chamber 140, and an end surface of the first door section 1a is connected to an end surface of the second door section 1 b.
