PROBLEM TO BE SOLVED: To reduce the size of an outdoor unit by retaining a space to install a liquid-liquid heat exchanger and a solenoid valve in a bathroom indoor unit relating to a bathroom heating apparatus with a mist function which has the bathroom indoor unit installed in a bathroom and the outdoor unit installed outside the bathroom for supplying a heating medium to the bathroom indoor unit.SOLUTION: In the bathroom heating apparatus 1 with a mist function, an indoor unit 2 has a function for generating warm water for spraying, and the liquid-liquid heat exchanger 15 for mist, an opening/closing valve 16 for a mist heating medium, and an opening/closing valve 17 for mist water are provided inside a casing 12. The opening/closing valve 16 for a mist heating medium is directly connected to a heating medium inlet 20 from among four openings of the liquid-liquid heat exchanger 15 for mist. The most part of a solenoid part 51 and a valve body 52 of the opening/closing valve 16 for a mist heating medium overlaps a rectangular region of the liquid-liquid heat exchanger 15 for mist.COPYRIGHT: (C)2010,JPO&INPIT【課題】浴室内に設置される浴室室内機と、浴室外に設置され浴室室内機に熱媒体を供給する屋外ユニットとを備えたミスト機能付浴室暖房装置に関するものであり、浴室室内機内に液液熱交換機や電磁弁を設置する空間を確保し、屋外ユニットを小型化することを課題とする。【解決手段】ミスト機能付浴室暖房装置1では、浴室室内機2に噴霧用の温水を作る機能を持たせており、筐体12内に、ミスト用液液熱交換器15と、ミスト熱媒用開閉弁16と、ミスト水用開閉弁17とを備えている。ミスト用液液熱交換器15の4個の開口の内、熱媒入口20にミスト熱媒用開閉弁16が直接的に接続されている。ミスト熱媒用開閉弁16のソレノイド部51及び弁体部52の大部分は、ミスト用液液熱交換器15の長方形の部位と重なる。【選択図】図4
