PROBLEM TO BE SOLVED: To provide a bathroom heating device with a mist sauna function which accurately determines the preparation completion of a mist sauna, and in which notification accuracy has been improved.SOLUTION: A bathroom heating device with a mist sauna function includes: bathroom temperature detection means for detecting the temperature in a bathroom 5 humidity detection means for detecting the humidity inside the bathroom a timer 20(16) for starting to count time when a mist sauna operation starts and notification control means 18(16) for notifying the preparation completion of the mist sauna at least when time of the timer is up. The notification control means 18 includes time-up delaying means 22(16). The time-up delaying means 22 delays the time-up of the timer 20, between the time the timer 20 starts counting and the time of time-up, when at least one of detection values of the temperature in the bathroom and the humidity in the bathroom changes from increase to decrease, in response to a period between the time the detection value changes to decrease and the time it restores to the value right before changing to decrease.COPYRIGHT: (C)2014,JPO&INPIT【課題】ミストサウナの準備完了を正確に判断して報知精度を向上させたミストサウナ機能付き浴室暖房装置を提供する。【解決手段】浴室5内の温度を検出する浴室温度検出手段と、浴室内の湿度を検出する湿度検出手段と、ミストサウナ運転の開始時に計時を開始するタイマ20(16)と、少なくともタイマがタイムアップしたとき、ミストサウナの準備完了を報知する報知制御手段18(16)とを備える。報知制御手段18は、タイムアップ遅延手段22(16)を備える。タイムアップ遅延手段22は、タイマ20が計時を開始してタイムアップするまでの間に、浴室の温度と浴室の湿度との少なくとも何れか一方の検出値が上昇から下降に転じたとき、その検出値が下降に転じてから下降に転じる直前の値に復帰するまでの時間に対応してタイマ20のタイムアップを遅延させる。【選択図】図1
