Description

本発明は、浴室内を暖房する暖房装置であって、湯水を霧状にして噴霧する機能を備えたミスト機能付浴室暖房装置に関するものである。   The present invention relates to a heating device that heats the inside of a bathroom, and relates to a bathroom heating device with a mist function that has a function of spraying hot water in the form of a mist.

保湿浴と称される入浴法が知られている。保湿浴は、入浴者が霧状雰囲気に入る入浴方法で、ミストサウナも保湿浴の一種である。ただしミストサウナは浴室内を高温状態に保つのに対し、保湿浴は低温状態の霧を使用する場合もある点でミストサウナよりも広い概念であると言える。
保湿浴は、ミストノズルを浴室内に設置し、高温又は常温の湯水をミストノズルから浴室内に噴霧し、入浴者がこの霧状雰囲気内に入る行為である。
保湿浴は、入浴者の心をリラックスさせる効果や、肌の潤いを高める効果かあり、心身の健康増進に役立つ。

従って、屋外ユニット3の燃焼装置30を稼働させ、循環ポンプを運転し、浴室室内機2内の熱動弁4を開くと、暖房用熱交換器6を通過する流路に熱媒体が流れ、暖房用熱交換器6によって浴室5内を昇温することができる。   Therefore, when the combustion device 30 of the outdoor unit 3 is operated, the circulation pump is operated, and the thermal valve 4 in the bathroom indoor unit 2 is opened, the heat medium flows through the flow path passing through the heat exchanger 6 for heating, The inside of the bathroom 5 can be heated by the heating heat exchanger 6.

また屋外ユニット3の燃焼装置30を稼働させ、循環ポンプを運転し、浴室室内機2内のミスト熱媒用開閉弁16と、ミスト水用開閉弁17とを開くと、浴室5内に湯の霧が噴霧される。
即ちミスト熱媒用開閉弁16を開くと、ミスト用液液熱交換器15の一次側流路が開いてミスト用液液熱交換器15の一次側に高温の熱媒体が流れる。またミスト水用開閉弁17とを開くと、ミスト用液液熱交換器15の二次側流路が開いてミスト用液液熱交換器15の二次側に水道水が流れる。その結果ミスト用液液熱交換器15内で熱媒体と水道水とが熱交換され。水道水が昇温してミスト用液液熱交換器15から排出され、ミストノズル7に流れ込む。そのためミストノズル7から湯が霧状に噴霧される。
Further, when the combustion device 30 of the outdoor unit 3 is operated, the circulation pump is operated, and the mist heat medium opening / closing valve 16 and the mist water opening / closing valve 17 in the bathroom indoor unit 2 are opened, Mist is sprayed.
That is, when the mist heat medium opening / closing valve 16 is opened, the primary flow path of the mist liquid-liquid heat exchanger 15 is opened, and a high-temperature heat medium flows to the primary side of the mist liquid-liquid heat exchanger 15. When the mist water on-off valve 17 is opened, the secondary flow path of the mist liquid-liquid heat exchanger 15 is opened, and tap water flows to the secondary side of the mist liquid-liquid heat exchanger 15. As a result, the heat medium and tap water are heat-exchanged in the mist liquid-liquid heat exchanger 15. The tap water is heated and discharged from the mist liquid-liquid heat exchanger 15 and flows into the mist nozzle 7. Therefore, hot water is sprayed from the mist nozzle 7 in the form of a mist.

またミスト用液液熱交換器15の厚さ(高さ)は、前記した短辺Bよりも小さい。またミスト用液液熱交換器15の厚さ(高さ)は、暖房用熱交換器6のそれよりも薄い。従って筐体12の前面部とミスト用液液熱交換器15の正面部との間には隙間がある。そして本実施形態では、この隙間にミスト熱媒用開閉弁16が設けられている。
The mist liquid-liquid heat exchanger 15 is a plate heat exchanger as described above, and has a substantially rectangular parallelepiped shape. Therefore, on the basis of the mounting posture, the mist liquid-liquid heat exchanger 15 is a rectangle having a long side A and a short side B, and is mounted in a posture in which the long side A is vertical and the short side B is horizontal. Yes.
Further, the thickness (height) of the mist liquid-liquid heat exchanger 15 is smaller than the short side B described above. Further, the thickness (height) of the liquid heat exchanger 15 for mist is thinner than that of the heat exchanger 6 for heating. Accordingly, there is a gap between the front surface of the housing 12 and the front surface of the mist liquid-liquid heat exchanger 15. In the present embodiment, a mist heat medium opening / closing valve 16 is provided in the gap.

即ち本実施形態では、図4の様にミスト用液液熱交換器15の4個の開口たる熱媒入口20、熱媒出口21、湯水入口22、湯水出口23は、いずれも取付け姿勢を基準として正面側に向いて開口している。
ミスト用液液熱交換器15を単独で観察すると、ミスト用液液熱交換器15の上に、熱媒入口20、熱媒出口21、湯水入口22、湯水出口23があるとも言える。
なお本実施形態では、取付け姿勢を基準として下側の短辺側に熱媒入口20と湯水出口23があり、上側の短辺側に熱媒出口21、湯水入口22がある。
That is, in this embodiment, as shown in FIG. 4, the four heating medium inlets 20, the heating medium outlet 21, the hot water inlet 22, and the hot water outlet 23 of the mist liquid-liquid heat exchanger 15 are all based on the mounting posture. It opens toward the front side.
When the mist liquid-liquid heat exchanger 15 is observed alone, it can be said that the heat medium inlet 20, the heat medium outlet 21, the hot water inlet 22, and the hot water outlet 23 are provided on the mist liquid liquid heat exchanger 15.
In the present embodiment, the heat medium inlet 20 and the hot water outlet 23 are provided on the lower short side with respect to the mounting posture, and the heat medium outlet 21 and the hot water inlet 22 are provided on the upper short side.

本実施形態では、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。そしてミスト熱媒用開閉弁16は、前記したミスト用液液熱交換器15の長方形形状に沿って縦置きされている。即ちミスト熱媒用開閉弁16は、その長手方向軸x−xがミスト用液液熱交換器15の長軸X−Xと平行になる姿勢で配置されている。また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。本実施形態では、ミスト熱媒用開閉弁16の全てがミスト用液液熱交換器15の長方形の部位と重なっているが、必ずしも全てが重なる必要はないが、ミスト熱媒用開閉弁16の80%以上の部位がミスト用液液熱交換器15の長方形の部位と重なることが推奨される。   In the present embodiment, the mist heat medium opening / closing valve 16 is directly connected to the heat medium inlet 20 among the four openings. The mist heat medium opening / closing valve 16 is vertically arranged along the rectangular shape of the mist liquid-liquid heat exchanger 15 described above. That is, the mist heat medium opening / closing valve 16 is arranged in such a posture that its longitudinal axis xx is parallel to the long axis XX of the liquid heat exchanger 15 for mist. Further, most of the solenoid part 51 and the valve body part 52 of the mist heat medium opening / closing valve 16 overlap with the rectangular part of the mist liquid-liquid heat exchanger 15. In the present embodiment, all of the mist heat medium opening / closing valves 16 overlap the rectangular portion of the mist liquid-liquid heat exchanger 15, but not all of them need to overlap. It is recommended that 80% or more of the parts overlap the rectangular part of the mist liquid-liquid heat exchanger 15.

前記した様に、ミスト用液液熱交換器15は、厚さの薄い直方体であり、その上部(取付け姿勢を基準とすると正面側)にミスト熱媒用開閉弁16が重なっているから、ミスト用液液熱交換器15の正面側の空間が有効利用される。   As described above, the mist liquid-liquid heat exchanger 15 is a thin rectangular parallelepiped, and the mist heat medium opening / closing valve 16 overlaps the upper part thereof (the front side when the mounting posture is used as a reference). The space on the front side of the liquid-liquid heat exchanger 15 is effectively used.

また本実施形態では、ミスト水用開閉弁17は、ミストノズル7の近傍に取り付けられている。
即ち本実施形態で採用する浴室室内機2は、筐体12内の向かって左寄りの位置にミスト用液液熱交換器15が内蔵されており、筐体12の右寄りの位置の下部に張り出し筐体55が設けられ、当該張り出し筐体55にミスト水用開閉弁17及びミストノズル7が配されている。
そのため前記した様にミスト水用開閉弁17は、ミストノズル7の近傍にある。
In the present embodiment, the mist water on-off valve 17 is attached in the vicinity of the mist nozzle 7.
That is, the bathroom indoor unit 2 employed in the present embodiment has a built-in mist liquid-liquid heat exchanger 15 at a position on the left side in the housing 12 and a projecting housing at a lower portion on the right side of the housing 12. A body 55 is provided, and the mist water on-off valve 17 and the mist nozzle 7 are arranged in the overhanging housing 55.
Therefore, as described above, the mist water on-off valve 17 is in the vicinity of the mist nozzle 7.

具体的には、ミスト用液液熱交換器15の下側短辺の位置に湯水出口23が設けられており、湯水出口23にノズル往き流路47の基端側が接続され、筐体12の張り出し筐体55に配されたミスト水用開閉弁17にノズル往き流路47の先端側が接続されている。そしてミスト水用開閉弁17の吐出側に、二本の接続管48が設けられ、当該接続管48にミストノズル7が接続されている。
ここで接続管48の長さは、ノズル往き流路47の長さに比べて十分に短く、具体的には、接続管48の長さは、ノズル往き流路47の長さの3分の1以下である。

Two connecting pipes 48 are provided on the discharge side of the mist water on-off valve 17, and the mist nozzle 7 is connected to the connecting pipe 48.
Here, the length of the connecting pipe 48 is sufficiently shorter than the length of the nozzle going flow path 47. Specifically, the length of the connecting pipe 48 is 3 minutes of the length of the nozzle going flow path 47. 1 or less.

前記した様に、屋外ユニット3の燃焼装置30を稼働させ、循環ポンプを運転し、浴室室内機2内のミスト熱媒用開閉弁16と、ミスト水用開閉弁17とを開くと、浴室5内に湯の霧が噴霧されるが、本実施経形態では、噴霧された霧状の湯水に雑菌が混入している可能性が低い。
即ち本実施形態では、ミストノズル7の近傍にミスト水用開閉弁17があり、霧の噴霧を停止している際には、ミスト水用開閉弁17が閉止され、ミスト水用開閉弁17を境として接続管48とノズル往き流路47側の間が遮断される。そのため、外部開放口たるミストノズル7の開口と接触し得る水は、接続管48の部分だけであり、例え外部開放口たるミストノズル7の開口から雑菌が混入したとしても、ミスト水用開閉弁17の上流側に雑菌が回り込むことはない。
そして本実施形態では、接続管48の長さが短いから、汚染された可能性のある湯水の量は微量であり、ミストノズル7から排出される湯水に雑菌が混入している可能性は低い。
As described above, when the combustion device 30 of the outdoor unit 3 is operated, the circulation pump is operated, and the mist heat medium opening / closing valve 16 and the mist water opening / closing valve 17 in the bathroom indoor unit 2 are opened, the bathroom 5 Hot water mist is sprayed inside, but in this embodiment, there is a low possibility that various germs are mixed in the sprayed mist of hot water.
That is, in this embodiment, there is a mist water on-off valve 17 in the vicinity of the mist nozzle 7, and when the spray of mist is stopped, the mist water on-off valve 17 is closed, and the mist water on-off valve 17 is opened. As a boundary, the connection pipe 48 and the nozzle going flow path 47 side are blocked. Therefore, the water that can come into contact with the opening of the mist nozzle 7 serving as the external opening is only the portion of the connecting pipe 48. Even if germs are mixed in from the opening of the mist nozzle 7 serving as the external opening, the on-off valve for mist water No bacteria enter the upstream side of 17.
In this embodiment, since the length of the connecting pipe 48 is short, the amount of hot water that may be contaminated is very small, and there is a low possibility that various bacteria are mixed in the hot water discharged from the mist nozzle 7. .
