Description

Soundproof and heat reserving door

The present invention relates to a sound insulation thermal insulation door, and more particularly, to a sound insulation thermal insulation door having a new configuration that minimizes noise inflow, foreign matter penetration, and indoor heat loss.

In general, the structure of a door used as an entrance door to a house, department store, shopping mall, etc. is fixed by means of a fixing means that can rotate the door to the frame so that the door can be opened and closed by rotating around one side. The means are provided with hinge shafts on the upper and lower sides, and there are couplings for fixing and hinges.

If the soundproof door is described as an example among the various types of doors described above, the soundproof door is a door that borders the exterior and the interior, such as an apartment or a detached house, and is made by embedding a soundproof member inside the front and rear door plates. One side of the door is hinged to the door frame provided on the wall, or a hinge is used to open and close the doorway.

However, in the case of the existing soundproof door, a mutual gap occurs between the door frame and the door in contact with it, so that the soundproof and airtight are not maintained as desired due to the gap, and at the same time, the inflow of external air is made, resulting in a lot of energy loss during heating and cooling. There is this. In addition, there are many cases in which external dust or the like flows into the room and adversely affects the indoor environment.
