PROBLEM TO BE SOLVED: To provide a device for heating washing liquid, capable of heating a large amount of washing liquid in a short time and highly accurately detecting the amount of supplied liquid.SOLUTION: The device 1 for heating washing liquid includes: a sealing type heat insulating chamber 3 for accommodating a washing liquid container 2 reserving a washing liquid a hot wind supply means 4 for circulating heated air A into the heat insulating chamber 3 and a weight measuring section 5 arranged in the heat insulating chamber 3 and used to hold the washing liquid container 2 by a hanging-down method to measure the weight of the washing liquid container 2 reserving the washing liquid. In the device 1, the hot wind supply means 4 is equipped with an inlet port 13 of the heated air A at a position where the washing liquid container 2 is not arranged on an extension line in the inflow direction of the heated air A into the heat insulating chamber 3.COPYRIGHT: (C)2012,JPO&INPIT【課題】大量の洗浄液を短時間で加温し、かつ、その供給量を精度よく検出する。【解決手段】洗浄液を貯留した洗浄液容器2を収容する密閉式の保温室3と、該保温室3内に加熱された空気Aを流動させる温風供給手段4と、保温室3内に配置され、洗浄液容器2を吊り下げ式に保持して洗浄液を貯留した洗浄液容器2の重量を測定する重量測定部5とを備え、温風供給手段4が、保温室3内への加熱空気Aの流入方向の延長線上に洗浄液容器2が配置されない位置に、加熱空気Aの流入口13を備える洗浄液加温装置1を提供する。【選択図】図1
