Definitions

  • the present invention relates to a display box, in particular to an improved display box in which condensation is prevented even in a place including high humidity such like a bath room so that a display screen can be visualized clearly.
  • the display device In case of where a display device having display screen such like a television is set within the bath room, the display device has been put in the display box and has been set in order to protect the display device from the mois­ture.
  • the display box contains a transparent panel with which the display screen of the display device faces. In such kind of display box, condensation is generated on the outer surface of the transparent panel, so that the display screen becomes difficult to be visualized.
  • the object of the present invention is to provide an improved display box, wherein condensation of the transpar­ent panel is prevented and the display screen is always visualized clearly.
  • the present invention provides a display box containing a display device having a display screen and comprising a transparent panel at the position opposed to the display screen, wherein an ultrasonic oscillator for driving the transparent panel is provided.
  • micro water droplet adhered or is going to adhere to the transparent panel surface is diverged by that the transpar­ent panel is driven by the ultrasonic wave, thereby prevent­ing moisture condensation on the transparent panel.
  • Fig. 1 is a plane view of the display box according to one embodiment of the present invention
  • Fig. 2 is a sectional view according to II-II line of Fig. 1.
  • a display box 1 has an opening at the front surface thereof and a transparent panel 2 is attached to the opening.
  • a step is provided at the back side of a margin of the opening and is engaged with the step of the margin of the panel.
  • a display device 4 is set at the back side of the transparent panel 2 in which a display screen 4a is faced with the transparent panel 2.
  • the reference numeral 3 shows a bracket for supporting the display device 4.
  • a circuit board 5 is provided at the back surface of the display device 4 within the display box 1, and the circuit board 5 is coupled to the display device 4 by means of a lead line 6.
  • the circuit board 5 is coupled to a supersonic oscillator 11 through a lead line 7.
  • the super­sonic oscillator 11 is adjacent to the back surface of the transparent panel 2 and is supported in the state of being pressed to the back surface of the transparent panel 2 by means of a support angle 12.
  • a switch 9 for controlling sound volume and for switch­ing channel is provided at side portion of the transparent panel 2 as shown in Fig. 1, and the switch 9 is coupled to the circuit board 5 by means of the lead line (not shown).
  • a reference numeral 10 of Fig. 2 shows a power cable.
  • the supersonic oscillator 11 is actuated to vibrate the trans­parent panel 2 with fine and high frequency. So, the micro water droplet adhered or is going to adhere to the outer surface of the transparent panel 2 is diverged, thereby preventing condensation on the transparent panel 2. There­fore, even if such display box is set in the place where it includes high humidity such like the bath room, the display screen 4a can be visualized clearly at all times.
  • Fig. 3 is a plane view of the display box according to another embodiment of the present invention.
  • Fig. 4 is a sectional view according to IV-IV line of Fig. 3.
  • a frame 2a is fixed at the margin of the transparent panel 2, and the supersonic oscillator 11 is adjacent to the back surface of the frame 2a.
  • the supersonic oscil­lator 11 in this embodiment has a long shape extending along each edge of the transparent panel 2.
  • the other structure is same as that in Figs. 1 and 2, and the same mark shows the same portion respectively.
  • the present invention can use other shaped box than that as shown in Figs. 1 to 4.
  • the switch 9 can be provided at other position than that as shown in the drawings.
  • the display box can be composed of the transparent material at the portion other than the transparent panel, and the whole of the box can be composed of the transparent material.
