FIG. 1 is an exploded perspective view of an in-wall type multi-functional television set according to an embodiment of the present invention.FIG. 2 is a partial cross-sectional view of the in-wall type multi-functional television set shown inFIG. 1 . - The in-wall type
multi-functional television set 100 includes a fixedcase 110, amain body 130 accommodated in the fixedcase 110, a horizontal adjustingpart 120 provided between themain body 130 and the fixedcase 110 and coupled to each of themain body 130 and the fixedcase 110, and adisplay device 170 coupled to themain body 130 with ahinge assembly 150. - The fixed
case 110 includes anopening 111 and an inner space so that themain body 130 can be accommodated. A plurality ofscrew connection holes 112 for connection with the horizontal adjustingpart 120 is formed on an inner surface of the fixedcase 110. The fixedcase 110 is provided on awall 10 of a room, such as a wall of a kitchen or a bath. For this purpose, a mounting recess 11 having a size corresponding to the size of thefixed case 110 is formed on thewall 10. Thefixed case 110 is accommodated and fixed in themounting recess 11. Thefixed case 110 may be fixed to the mounting recess 11 with cement or the like. A lattice-like recess (not shown) may be formed on a rear surface of the fixedcase 110 so that the fixedcase 110 can be more securely fixed to themounting recess 11. Aframe 115 is stably fixed to the fixedcase 110 to support the edge of themain body 130. - The
main body 130 is equipped with acontroller 141 for controlling the entire system, and includes anaccommodating part 131 formed to accommodate thedisplay device 170. Thedisplay device 170 includes apanel 171 which is provided to display an image, andspeakers 172 which are provided on both sides of thepanel 171. Thedisplay device 170 is mechanically coupled to themain body 130 with thehinge assembly 150. For this purpose, screw connection holes are formed on a rear surface of thedisplay device 170 to be coupled with afirst fixing bracket 151 of thehinge assembly 150, and afirst connection part 175 is provided so that thefirst fixing bracket 151 can be inserted. In addition, screw connection holes are formed in theaccommodating part 131 of themain body 130 to be coupled with asecond fixing bracket 152 of thehinge assembly 150, and asecond connection part 132 is provided so that thesecond fixing bracket 152 can be inserted. Preferably, screws fastened to thesecond fixing bracket 152 are fastened to thesecond connection part 132 and at least one of the screws is fastened to the horizontal adjustingpart 120 through thesecond connection part 132. Hence, thedisplay device 170 can be prevented from sagging downwards due to its weight when it is withdrawn from theaccommodating part 131. Themain body 130 is electrically connected to thedisplay device 170 through aconnection cable 180 such as a flexible printed circuit board.

device 170 coupled to themain body 130 with thehinge assembly 150 is indirectly coupled to the fixedcase 110. Thus, in case the fixedcase 110 is not exactly horizontally fixed when it is provided in thewall 10, thedisplay device 170 is not exactly horizontally adjusted. As a result, thedisplay device 170 may be inclined when viewed by users. This can be adjusted to be level by thehorizontal adjusting part 120 provided between the fixedcase 110 and themain body 130. - Referring to
FIG. 3 , thehorizontal adjusting part 120 has a plate shape and includes a plurality of adjustingholes 121 which is fastened with screws to the screw connection holes 112 of the fixedcase 110. Each of the adjusting holes 121 has a shape corresponding to a movement trajectory of thescrew connection hole 112, which is caused by relative rotation between thehorizontal adjusting part 120 and the fixedcase 110. That is, the adjustinghole 121 is formed such that even though thehorizontal adjusting part 120 rotates about the fixedcase 110 at a predetermined angle, thescrew connection hole 112 remains located in the adjustinghole 121 and screws are connected to both of thescrew connection hole 112 and the adjustinghole 121. Preferably, the adjustinghole 121 has a trajectory so that thedisplay device 170 can be freely horizontally adjusted. Even though the fixedcase 110 is not exactly horizontally provided in thewall 10, thedisplay device 170 is not exactly horizontally adjusted. As a result, thedisplay device 170 may be inclined when viewed by users. This can be adjusted to be level by thehorizontal adjusting part 120 provided between the fixedcase 110 and themain body 130. - Referring to
FIG. 3 , thehorizontal adjusting part 120 has a plate shape and includes a plurality of adjustingholes 121 which is fastened with screws to the screw connection holes 112 of the fixedcase 110. Each of the adjusting holes 121 has a shape corresponding to a movement trajectory of thescrew connection hole 112, which is caused by relative rotation between thehorizontal adjusting part 120 and the fixedcase 110. That is, the adjustinghole 121 is formed such that even though thehorizontal adjusting part 120 rotates about the fixedcase 110 at a predetermined angle, thescrew connection hole 112 remains located in the adjustinghole 121 and screws are connected to both of thescrew connection hole 112 and the adjustinghole 121. Preferably, the adjustinghole 121 has a trajectory so that thedisplay device 170 can be freely horizontally adjusted. Even though the fixedcase 110 is not exactly horizontally provided when it is provided in thewall 10, thedisplay device 170 can be adjusted to be horizontal by means of the adjustinghole 121 formed in thehorizontal adjusting part 120. - The
