The present invention relates to a greenhouse having improved hot air supplying efficiency and drying efficiency. The greenhouse of the present invention includes: a greenhouse body which has a work space formed therein, has at least one ventilating hole formed in one top side thereof, and is made of a transparent material to enable light to penetrate; a hot air supplying means which is installed on the outside of or inside the greenhouse body and supplies hot air; a side direction hot air supplying unit which is installed in the length direction of the greenhouse body in the greenhouse body, has one side connected with the hot air supplying means, includes a plurality of discharging holes which are separately formed at particular intervals along a length direction, and supplies hot air into the greenhouse body through the discharging holes; and an ascending air flow forming unit which is installed at one bottom side in the greenhouse body, has one side connected with the hot air supplying means, includes at least one spraying hole in one side thereof, and sprays hot air to the top thereof. According to the present invention, hot air is horizontally supplied to the ground in the greenhouse body, and hot air is upwardly sprayed from the bottom surface of the greenhouse body, so that an ascending air flow is formed. Hot air is uniformly supplied to the overall inside of the greenhouse body, so that drying efficiency can be maintained irrespective of the position in which a material to be dried is disposed. Also, ventilating efficiency is improved, so that the inside of the greenhouse body can be cleanly maintained. |
