。Conventionally, hot air generators heated a heat exchange part using electric heat or combustion heat, and circulated air thereto to obtain warm air. Electricity is preferable from a safety standpoint, but the energy cost of electricity is higher than that of other sources, and in order to improve the startup of the heat exchanger, the scale of the heat source must be made larger than necessary. This results in poor thermal efficiency and increased equipment costs.

３は熱交換部分で、立上りパイプ２の途中から水平方向
へ分岐した多数のパイプからなっており、各パイプには
熱交換効率を向上させるためにフィン４が設けられてい

５は下降パイプで、熱交換部分３のパイプが連結してお
り、傾斜バイブロを経てタンクｌに戻る。Reference numeral 5 denotes a descending pipe, to which the pipe of the heat exchange section 3 is connected, and returns to the tank 1 via the inclined vibro.
エチレンクリコールは熱交換部分３の全部に行き亘るよ
うに満たされている。Ethylene glycol is filled throughout the heat exchange section 3.
７は電気ヒータで、タンク１内のエチレンクリコールを
所定温度まで加熱する。An electric heater 7 heats the ethylene glycol in the tank 1 to a predetermined temperature.
８はコックバルブでエチレングリコールの循環を停止す
る。8 is a cock valve to stop the circulation of ethylene glycol.
９は補助タンクで、連絡パイプ１０により下降パイプ５
の下端部に連通し、熱交換部分３のエチレングリ５−ル
の上限水位に対応する位置に設けである。9 is an auxiliary tank, and a descending pipe 5 is connected by a connecting pipe 10.
It communicates with the lower end of the heat exchange section 3, and is provided at a position corresponding to the upper limit water level of the ethylene grill 5 of the heat exchange section 3.
下降パイプ５の上端部と補助タンク９の上端部には大気
に通じる通気孔１１が設けられている。A vent hole 11 communicating with the atmosphere is provided at the upper end of the descending pipe 5 and the upper end of the auxiliary tank 9.
１２はファンで、モータ１３により回転し、熱交換部３
を流過して空気を送風する。Reference numeral 12 denotes a fan, which is rotated by a motor 13 and is connected to the heat exchanger 3.
The air is blown through the air.
このように構成されていて、コックバルブ８を閉じたま
ま電気ヒータ７をＯＮにすると、タンク１内のエチレン
グリコールは所定温度まで次第に加熱される。この場合
エチレングリコールの沸点が高いので電気ヒータ７のパ
ワーが小さくても長時間の間に大量の熱が蓄熱される。With this structure, when the electric heater 7 is turned on with the cock valve 8 closed, the ethylene glycol in the tank 1 is gradually heated to a predetermined temperature. In this case, since ethylene glycol has a high boiling point, a large amount of heat is stored over a long period of time even if the power of the electric heater 7 is low.

果を良くする。When the cock valve 8 is opened to start blowing air to the fan 1r-2, the heated ethylene glycol rises in the riser pipe 2, passes through the heat exchange section 3, and flows from the descender pipe 5 through the inclined vibro to the tank. Natural convection returns to l. In this case, if the substantially horizontal pipe of the heat exchange section 3 is inclined slightly downward in the direction in which the heat medium advances, the convection effect will be further improved.

によって内圧が上昇するのを防止するものである。The heat exchange portion 3 rapidly becomes high in temperature, and the fan 12 blows air to immediately obtain hot air at the required temperature. The auxiliary tank 9 is a gauge that can externally detect the upper limit liquid level of the heat medium in the heat exchange section, and is also an ethylene glycol injection port. Further, the vent holes 11 are provided to prevent internal pressure from increasing due to thermal expansion of ethylene glycol.

しも必要ではない等の著効を奏する。As mentioned above, since the hot air generator according to the present invention uses ethylene glycol as a heat medium, it has a heat storage effect even if it supplies thermal energy in small amounts, and the hot air supply starts up quickly, and when necessary. can extract high-temperature air,
It is especially effective when used for purposes such as drying, and has excellent thermal efficiency at high temperatures.The high boiling point means less evaporation of the heating medium itself, and the low freezing point prevents freezing, and there is no problem with rust on pipes, etc. Since the specific heat is small, heat exchange is good, and although natural convection occurs, forced RAM is not necessarily necessary.
